Using Nvidia Graphics Drivers With Initial Optimus Support In Ubuntu 13.10 Got Easier With Nvidia-Prime

<div style="text-align: justify;">As you probably know, the Nvidia graphics drivers have received <a href="http://www.webupd8.org/2013/04/nvidia-releases-linux-graphics-drivers.html">initial Optimus support</a> a while back. Currently, the Nvidia GPU can be used to render the desktop, but there's no power saving yet. That means you can for instance play games or watch videos using hardware acceleration.</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">But to be able to take advantage of this feature in the latest Nvidia drivers, you need up-to-date dependencies (such as Randr 1.4, Xorg 1.13 - that's what the initial Nvidia release notes mention, but it seems you actually need 1.14 -, Linux Kernel 3.9 with some special flags enabled), as well as a custom xorg.conf file and some other bits.</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">That means that out of the box, the only Ubuntu version that can use this initial <a href="http://en.wikipedia.org/wiki/Nvidia_Optimus">Optimus</a> support in the Nvidia graphics drivers is Ubuntu 13.10 Saucy Salamander, but even in Saucy, you need to configure some things to get it to work.</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;"><b>If you're using Ubuntu 13.10 Saucy Salamander, things got a lot easier and you don't need to configure anything to be able to take advantage of this Optimus feature in the Nvidia graphics drivers 319.12+: a package called "<a href="https://launchpad.net/ubuntu/+source/nvidia-prime">nvidia-prime</a>", which comes with a set of tools that enable Nvidia's Prime on MUXless systems, has been uploaded to the Ubuntu 13.10 Saucy Salamander repositories</b> about a month ago and it has currently reached version 0.4 (released today).</div><br /><a name='more'></a><div style="text-align: justify;">This package automatically checks if your system supports Nvidia Optimus and the required packages, creates the xorg.conf file and tweaks the LightDM configuration to support this.</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">In my test, I've installed the Nvidia 319.32 drivers and the "nvidia-prime" package (both from the Ubuntu 13.10 repositories) and after a reboot, the Nvidia card was used on my Optimus laptop (Dell XPS L702X):</div><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto;

Bumblebee 3.2.1 Released With Ubuntu 13.04 Fixes, New Options

<div style="text-align: justify;"><b>Bumblebee 3.2 has been released a few days ago but there was an issue and it didn't work on a lot of setups o version 3.2.1 has been released to fix this. The new version also fixes the Primus backend for Ubuntu 13.04 and adds some new options.</b></div><div style="text-align: justify;"><br /></div><div style="text-align: justify;"><i><a href="http://bumblebee-project.org/">Bumblebee</a> is an unofficial tool that brings Nvidia Optimus GPU switching to Linux. It's useful to increase battery life by only switching the dedicated GPU (Nvidia) on when needed. Nvidia has added <a href="http://www.webupd8.org/2013/04/nvidia-releases-linux-graphics-drivers.html">initial Optimus support</a> in their latest 319.12 beta drivers, but it doesn't have GPU switching yet.</i></div><br /><a name='more'></a><b>Bumblebee 3.2 comes with the following changes:</b><br /><ul><li style="text-align: justify;">new option: "-b" to disable injection of any render offloading bridge (primus or VirtualGL). Use this to invoke nvidia-settings (optirun -b none nvidia-settings -c :8)<i>;</i></li><li style="text-align: justify;">new option: "--no-xorg" for optirun to disable starting secondary X server. Use this to run CUDA or OpenCL applications that do not need the graphics rendering capabilities. Implies "-b none";</li><li style="text-align: justify;">Bumblebee no longer depends on the primusrun script anymore for the Primus backend. However, "primusrun" and "optirun -b primus" have different behaviors: the first one powers on the discrete GPU when needed while the second one will immediately do this; the difference in behavior is most noticeable with WebGL content in Firefox;</li><li style="text-align: justify;">Added support for passing <i>-configdir</i> to X, defaulting to <i>/etc/bumblebee/xorg.conf.d</i>,<i> --xconfdir</i> option added to bumblebeed and XorgConfDir added to <i>bumblebee.conf</i>; this finally fixes a long-standing annoyance with SNA config option for the Intel driver;</li><li style="text-align: justify;">the BusID is added automatically on Ubuntu 13.04 so users no longer need to do this manually. Without this, Bumblebee failed to work on Ubuntu 13.04;</li><li style="text-align: justify;">fix: added <i>/usr/$LIB/mesa/libGL.so.1</i> to default primus libGLd for supporting Ubuntu 13.04;</li><li style="text-align: justify;">fix: fixed a "buffer overflow" issue in bumblebeed;</li><li style="text-align: justify;">fix: removed accesses to PCI config space from the daemon process.</li></ul><br /><br /><div style="text-align: justify;">Also, <b><a href="http://www.webupd8.org/2013/04/set-up-bumblebee-with-bumblebee.html">Bumblebee Configurator GUI</a></b>, a tool that allows you to easily setup Bumblebee, has been <b>updated recently with support for the latest Bumblebee 3.2</b>. <b>The latest version also adds an option to install Bumblebee in Ubuntu</b>.</div><br /><br /><br /><h2>Install Bumblebee Configurator GUI in Ubuntu</h2><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjFH2WxRju9zKCfbGmfS_LUX2vUKBq57qoqO_aFakjIfyjwLK3e_NnzaiN7gYAgdK8viUdFBzXn3hjrH1LepblhUDYjRIUB4KIeO1yhKqkw6URIl4lz3ZIItRpzNVlVZierePzJTsn2LbAI/s1600/bumblebee-config_1.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="Bumblebee Configurator GUI" border="0" height="231" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjFH2WxRju9zKCfbGmfS_LUX2vUKBq57qoqO_aFakjIfyjwLK3e_NnzaiN7gYAgdK8viUdFBzXn3hjrH1LepblhUDYjRIUB4KIeO1yhKqkw6URIl4lz3ZIItRpzNVlVZierePzJTsn2LbAI/s320/bumblebee-config_1.png" title="Bumblebee Configurator GUI" width="320" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgkZPW9pWgovei-2iC0KDqI4fgcwSvKBp8LRS51JHWIgXjsiZrch55BqhlsTrajQgLYBHoEy8yqnsBnHoDcb49mPVrbaA2KuSBySodCSSUxI1TBtiIZf34VNEVSvEVtnUcRtCm5IMz0nRAj/s1600/bumblebee-config_2.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="Bumblebee Configurator GUI" border="0" height="222" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgkZPW9pWgovei-2iC0KDqI4fgcwSvKBp8LRS51JHWIgXjsiZrch55BqhlsTrajQgLYBHoEy8yqnsBnHoDcb49mPVrbaA2KuSBySodCSSUxI1TBtiIZf34VNEVSvEVtnUcRtCm5IMz0nRAj/s320/bumblebee-config_2.png" title="Bumblebee Configurator GUI" width="320" /></a></div><div style="text-align: justify;"><br /></div><div style="text-align: justify;"><br /></div><div style="text-align: justify;"><b>To install Bumblebee Configurator GUI in Ubuntu, use the following commands:</b></div><pre class="linux-code"><code>sudo add-apt-repository ppa:alessandrofac93/bumblebee-config-gtk-dev<br />sudo apt-get update<br />sudo apt-get install bumblebee-config-gui</code></pre><br /><div style="text-align: justify;">Then, you launch the application and use it to install and set up Bumblebee.

<div style="text-align: justify;"><b>Nvidia has released a new beta version of their Linux graphics today: <a href="http://www.nvidia.com/object/linux-display-ia32-319.12-driver.html">319.12</a>, which includes quite a few changes, including initial Optimus support.</b></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjYMPp4yChvWxSm7h-qiVPVCJtnnUmmx74LQZfilcPp9sTXeIyhCXOqnVo5gZb_lxO02pLcIumIeZgNGaRfse2V74ZP2p3bCXKkOf7f1H3AJ9wfHWVxKXlAd2DStvatfBiic68LbV1B3CHR/s1600/nvidia-logo.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="nvidia logo" border="0" height="171" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjYMPp4yChvWxSm7h-qiVPVCJtnnUmmx74LQZfilcPp9sTXeIyhCXOqnVo5gZb_lxO02pLcIumIeZgNGaRfse2V74ZP2p3bCXKkOf7f1H3AJ9wfHWVxKXlAd2DStvatfBiic68LbV1B3CHR/s200/nvidia-logo.jpg" title="nvidia logo" width="200" /></a></div><br /><div style="text-align: justify;"><i><a href="http://en.wikipedia.org/wiki/Nvidia_Optimus">Nvidia Optimus</a> is a technology used to increase battery life by switching the dedicated GPU (Nvidia) off when it's not needed; when the dedicated GPU is off, the integrated graphics chip (Intel) is used. Until now, Linux users could take advantage of this technology through an unofficial project called <a href="http://www.webupd8.org/2013/02/bumblebee-31-released-with-primus.html">Bumblebee</a>.</i><br /><br /><a name='more'></a><br />The Nvidia 319.12 beta Linux display driver changelog doesn't explicitly mention Optimus support, however, the following can be found in the <a href="http://www.nvidia.com/object/linux-display-amd64-319.12-driver.html">release notes</a>: </div><br /><blockquote class="tr_bq">"Added initial support for RandR 1.4 Provider objects with the Source Output capability, which can be used to render the desktop on an NVIDIA GPU and display it on an output connected to a provider with the Sink Output capability, such as an Intel integrated graphics device or a DisplayLink USB-to-VGA adapter". </blockquote><br /><div style="text-align: justify;">Furthermore, the Nvidia 319.12 beta graphics drivers <a href="http://us.download.nvidia.com/XFree86/Linux-x86/319.12/README/randr14.html">README</a> gives some extra info on the graphics display offloading with RandR 1.4:</div><br /><blockquote class="tr_bq">"Version 1.4 of the X Resize, Rotate, and Reflect Extension (RandR 1.4 for short) adds a way for drivers to work together so that one graphics device can display images rendered by another. This can be used on Optimus-based laptops to display a desktop rendered by an NVIDIA GPU on a screen connected to another graphics device, such as an Intel integrated graphics device or a USB-to-VGA adapter."</blockquote><br /><br /><div style="text-align: justify;">To be able to make use of the initial Optimus support in the latest Nvidia Linux graphics drivers, you'll need Xorg 1.13 or higher, xrandr command line utility version 1.4.0, a custom <i>xorg.conf</i> configuration which you can find in the drivers <a href="http://us.download.nvidia.com/XFree86/Linux-x86/319.12/README/randr14.html">README</a>, Linux Kernel with CONFIG_DRM enabled and the appropriate driver interfaces present (more on that, in the same README) and obviously, an Optimus-based laptop.</div><br /><div style="text-align: justify;">For now, the latest Nvidia 319.12 beta drivers don't work in Ubuntu by default, not even in Raring, because while Ubuntu has RandR 1.4, the xrandr command line utility version is 1.3.5. Furthermore, I'm not sure if the Ubuntu Kernel supports it (see above).<br /><br />Update: TiborB has pointed out in a <a href="http://www.webupd8.org/2013/04/nvidia-releases-linux-graphics-drivers.html#comment-858631862">comment</a> that xrandr 1.3.5 that's available in Ubuntu Raring already has some 1.4 features so it might be enough for this to work but I haven't looked too much into this. I've tried the drivers yesterday in Ubuntu Raring on my Optimus-based laptop but I couldn't get it to work. I'll give it another try sometime (hopefully soon) to see if Ubuntu 13.04 Raring Ringtail users can get the initial Optimus support that's available in the Nvidia 319.12 graphics drivers.<br /></div><br /><b>Other changes in Nvidia 319.12 beta Linux graphics drivers:</b><br /><ul><li style="text-align: justify;">added support for GeForce GTX 650 Ti BOOST;</li><li style="text-align: justify;">added initial support for restoration of efifb consoles on UEFI systems; where the primary display is driven over VGA or TMDS (e.g. DVI, HDMI, or LVDS);</li><li style="text-align: justify;">added support for the xorg.conf Monitor section options "Ignore", "Enable", "Primary", and "Rotate";</li><li style="text-align: justify;">added an Underscan feature in the nvidia-settings X Server Display Configuration page which allows the configuration of an underscan border around the ViewPortOut.This feature was formerly known as Overscan Compensation;</li><li style="text-align: justify;">added support for application profiles to the NVIDIA client-side GLX implementation;</li><li style="text-align: justify;">added support to nvidia-installer for crytographically signing the NVIDIA kernel module;</li><li style="text-align: justify;">added nvidia-modprobe, a setuid root utility, to the driver package. nvidia-modprobe can be used by user-space NVIDIA driver components to make sure the NVIDIA kernel module is loaded and that the NVIDIA character device files are present;</li><li style="text-align: justify;">added a VDPAU page to the nvidia-settings control panel, to display information about the decoding capabilities of VDPAU-capable GPUs</li><li style="text-align: justify;">various other improvements and bug fixes; for the complete changelog, see the <a href="http://www.nvidia.com/object/linux-display-amd64-319.12-driver.html">Nvidia Linux Drivers 319.12 Beta</a> page.</li></ul><br /><br /><b>Download Nvidia Linux Graphics Drivers 319.12 Beta: <a href="http://www.nvidia.com/object/linux-display-ia32-319.12-driver.html">32bit</a> | <a href="http://www.nvidia.com/object/linux-display-amd64-319.12-driver.html">64bit</a></b><br /><br /><br /><div style="text-align: right;"><i>via <a href="http://www.phoronix.com/scan.php?page=news_item&px=MTM0NzE">phoronix</a></i></div>

Primus: Better Performance And Less Power Consumption For Bumblebee [Optimus Hybrid Graphics Chipsets]

Optimus GPU switching is officially only supported on Windows, but it's also unofficially available on Linux thanks to the Bumblebee project.</i></div><div style="text-align: justify;"><br /></div><div style="text-align: justify;"><b><a href="https://github.com/amonakov/primus">Primus</a> brings better performance and less power consumption when using <a href="http://www.bumblebee-project.org/">Bumblebee</a></b>, by replacing VirtualGL. According to the Bumblebee <a href="http://www.bumblebee-project.org/g+">G+</a> page, this has the following <b>advantages over the optirun (VirtualGL) solution</b> used by default in Bumblebee:</div><a name='more'></a><ul><li>Less overhead (better framerates) and cleaner solution (no networking or compression involved at all)</li><li>Fixes the "bug" that causes Bumblebee to shut down the GPU too early sometimes (no more need for the "optirun bash" workaround)</li><li>Less buggy/glitchy, easier to debug</li><li>Only uses/starts secondary GPU for OpenGL parts of applications - everything else remains on your main GPU (power savings)</li></ul><br />The Bumblebee developers explain what Primus does and the difference between Primus / optirun in simple terms in a comment on their G+ page:<br /><br /><blockquote>Bumblebee uses VirtualGL to copy the image generated by the second (faster) GPU to your display. VirtualGL was intended for use over a network though, so it takes a great many steps to enable this (compression, sending the image over a network link, decompression, etc).<br /><br />Primus doesn't perform all these "extra" steps, instead taking a more direct route (copying the rendered image in memory to the other GPU, then displaying there). In theory this should get you better performance as well as better compatibility. Running applications will "see" the OpenGL implementation of your real hardware, nothing virtual is presented to them.</blockquote><br /><div style="text-align: justify;">For comparison, here are the framerates I get on my laptop when using the integrated Intel graphics, when using the Nvidia graphics card using optirun and using primusrun (this is just for FPS and not an indicator for the whole performance!): </div><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody><tr><td style="text-align: center;"><a href="http://netupd8.com/w8img2/glxspheres-regular.png" rel="image_group" style="margin-left: auto; margin-right: auto;" title="Using integrated (Intel) graphics"><img alt="glxspheres intel gpu" src="http://netupd8.com/w8img2/glxspheres-regular_thumb.png" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Integrated (Intel) graphics</td></tr></tbody></table><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody><tr><td style="text-align: center;"><a href="http://netupd8.com/w8img2/glxspheres-optirun.png" rel="image_group" style="margin-left: auto; margin-right: auto;" title="Using optirun (default in Bumblebee) with Nvidia GPU"><img alt="glxspheres optirun bumblebee" src="http://netupd8.com/w8img2/glxspheres-optirun_thumb.png" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">optirun (default in Bumblebee) using the Nvidia GPU</td></tr></tbody></table><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody><tr><td style="text-align: center;"><a href="http://netupd8.com/w8img2/glxspheres-primus.png" rel="image_group" style="margin-left: auto; margin-right: auto;" title="Using Primus with Nvidia GPU - best performance of the 3"><img alt="glxspheres primusrun bumblebee" src="http://netupd8.com/w8img2/glxspheres-primus_thumb.png" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Primus using the Nvidia GPU</td></tr></tbody></table><br /><div style="text-align: justify;">As you can see, the FPS using  Primus is a lot better than using the integrated graphics or using optirun with the Nvidia GPU.</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">Note: I've used "vblank_mode=0 primusrun" instead of simply running "primusrun" because that was recommended by the Primus GitHub page for benchmarking.

I've used LXDE so using the instructions below, you'll get an LXDE session on the monitor connected via HDMI.</div><br /><div style="text-align: justify;">To get the mouse and keyboard working on the external monitor connected via HDMI we'll use Synergy, a tool that lets you share the mouse and keyboard between multiple computers.</div><br /><b>Let's install the required packages (LXDE and Synergy):</b><br /><pre class="linux-code"><code>sudo apt-get install synergy lxde lxde-common</code></pre><br /><div style="text-align: justify;"><b>3.</b> To be able to use Synergy, you'll need to create a configuration file. You can download mine from <a href="http://webupd8.googlecode.com/files/synergy.conf">HERE</a> - copy the file to your home folder and rename it to ".synergy.conf" (notice the dot in front of the filename - that makes the file become hidden).</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">The file I've provided above should be enough, but if you want to change it, you can read about the Synergy configuration file <a href="http://synergy2.sourceforge.net/configuration.html">here</a>.</div><br /><div style="text-align: justify;"><b>4.</b> To start LXDE on the external monitor connected via HDMI, you can use a script which you can download from <a href="http://webupd8.googlecode.com/files/hdmi-0.1.tar.gz">HERE</a>. Extract the archive, copy the "hdmi" script to your home folder and make it executable using the following command:</div><pre class="linux-code"><code>chmod +x ~/hdmi</code></pre><br />Now, to run the script, use the following command:<br /><pre class="linux-code"><code>~/hdmi</code></pre><br /><div style="text-align: justify;">LXDE should now start on the external monitor connected via HDMI. Give it some time (around 10 seconds) and moving your mouse to the left of your screen should make it show up on the HDMI device.</div><br /><div style="text-align: justify;">Here's what the script does (this is just an explaination, you don't need to run these commands, just use the above script):</div><br />- exports the display to the one we're going to use for the HDMI monitor (8):<br /><pre class="linux-code"><code>export DISPLAY=:8.0</code></pre><br />- runs LXDE with optirun (Bumblebee):<br /><pre class="linux-code"><code>optirun startlxde &</code></pre><br /><div style="text-align: justify;">- runs the Synergy server in the foreground on the main display (on your laptop's main session) with 127.0.0.1 as the address: </div><pre class="linux-code"><code>synergys -f -a 127.0.0.1 --display :0 -n ubuntu &</code></pre><br /><div style="text-align: justify;">- runs the Synergy client in the foreground on the HDMI display and it connects it to the 127.0.0.1 server address:</div><pre class="linux-code"><code>synergyc -f -n hdmi --display :8 127.0.0.1 &</code></pre><br /><div style="text-align: justify;">And finally, it exports the display back to your laptop's (main) display:</div><pre class="linux-code"><code>export DISPLAY=:0.0</code></pre><br /><div style="text-align: justify;">The script also uses some "sleep" commands which add a delay to make sure the commands have enough time to get executed before running the next command.</div><br /><br /><br /><h2>Tips</h2><br /><b>Launching applications:</b><br /><br /><div style="text-align: justify;">To launch an application on the monitor connected via HDMI, you can use the LXDE menu on the external monitor or use the following command on your main session:</div><pre class="linux-code"><code>export DISPLAY=:8.0 APPLICATION</code></pre>where "APPLICATION" is the executable name for the app you want to launch.<br /><br /><div style="text-align: justify;">Optionally, you can also run "export DISPLAY=:8.0" in a terminal window on your main session, and then all the applications you launch from that terminal window should show up on the external monitor.</div><br /><br /><b>Configuring your Nvidia graphics card:</b><br /><br /><div style="text-align: justify;">Using the above instructions to launch applications on the external monitor, you can launch "nvidia-settings" (if you're using the proprietary Nvidia graphics drivers):</div><pre class="linux-code"><code>export DISPLAY=:8.0 nvidia-settings</code></pre><div style="text-align: justify;">Launching this on your laptop session displays an error message saying that you're not using Nvidia drivers, but launching in on the HDMI-connected device (which uses Bumblebee with "optirun"), you can configure various Nvidia settings: the screen resolution, etc.</div><br /><br /><b>Fixing double autostart applications / tray icons:</b><br /><br /><div style="text-align: justify;">To avoid getting double indicators (two network indicators, etc.) in your regular session when launching the extra LXDE session, you can make all autostart applications / applets to not load in our LXDE session, using the following commands:</div><pre class="linux-code"><code>for f in /etc/xdg/autostart/*; do if [[ ! `grep "NotShowIn=LXDE" $f` ]]; then echo "NotShowIn=LXDE;" | sudo tee -a $f; fi; done<br />for f in ~/.config/autostart/*; do if [[ ! `grep "NotShowIn=LXDE" $f` ]]; then echo "NotShowIn=LXDE;" | tee -a $f; fi; done</code></pre><br /><div style="text-align: justify;">You can also do this manually, by going to <i>/etc/xdg/autostart</i> and <i>~/.config/autostart</i> and adding "NotShowIn=LXDE;" (without the quotes) to each .desktop file corresponding to the application(s) you don't want to start in LXDE.
