Steam Machines: Valve Announces New Living-Room Hardware That Runs SteamOS

<div style="text-align: justify;"><b>Valve has announced a new category of living-room hardware today, that will be running <a href="http://www.webupd8.org/2013/09/valve-reveals-steamos-linux-based.html">Steam OS</a> and will be available in multiple configurations.

Once you complete these steps, you'll be awarded a special badge and be among the pool of people that can be chosen to test the new hardware.</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">According to Valve, the new Steam machines will be "completely upgradable and open" and starting next year, there will be multiple machines to choose from, made by different manufacturers.

The price may change in the future, but those who pre-order it now won't have to pay more if the price will increase and will get a refund if the final price will be lower.

We're an independent company developing a tablet which will ship with Canonical's software (which is GPL licensed).<br /><br />We've got the device currently under development, most of the work at the moment is getting the peripherals working under Ubuntu Touch. Obviously, we're highly dependent on when Canonical releases the final version of Ubuntu Touch, plus some time for us to test it before we start shipping.</blockquote><br />Peter has also said a video should be available on YouTube shortly, which he hopes will prove this is legit.</div><br /><a href="https://www.intermatrix.com.au/ubuntutablet/preorder.php">Pre-order the Intermatrix U7 Ubuntu Touch tablet</a><br /><br /><b>Update: the Intermatrix folks have changed their mind and are not shipping Ubuntu Touch anymore, at least for now!</b><br /><br /><br /><div style="text-align: right;"><i>via <a href="https://plus.google.com/u/0/101475532450986173690/posts/HM676HtZsqt">+Joshua Kiley</a> & <a href="https://plus.google.com/117353980479250980339/posts/LMFfZ1d2PZf">+Carl Draper</a></i></div>

I-Nex: Tool To List Hardware Information In Linux, Similar To CPU-Z

<div style="text-align: justify;"><b><a href="https://launchpad.net/i-nex">I-Nex</a> is an application that gathers information for hardware components available on your system and displays it using an user interface similar to the popular Windows tool CPU-Z.</b></div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">I-Nex can display information for the following components: CPU, GPU, Motherboard, Sound, Hard disks, RAM, Network and USB as well as some system info like the hostname, Linux distribution and version, Xorg, GCC, GLX versions and Linux Kernel info.</div><br /><div style="text-align: justify;">Besides being able to display hardware information, I-Nex can also generate an advanced report for which you can select what to include and optionally send the report to a service such as Pastebin (and others).

Get HDMI Working With Nvidia Optimus On Ubuntu By Using Bumblebee And Synergy

<div style="text-align: justify;"><b>HDMI doesn't work with Optimus hybrid graphics chipsets under Linux for most laptops, even if you use Bumblebee, but there is a way to get HDMI to work: by using a separate session.</b></div><br /><a name='more'></a><div style="text-align: justify;">Using the instructions below, you'll get an LXDE session (you can use XFCE or others, but the instructions below are for LXDE) to show up on the external monitor (which is connected via HDMI), and in this session, all the applications you launch use your laptop's Nvidia graphics card and you can play games, watch movies, etc. The LXDE session runs in the same time as your regular session, so on your laptop's screen you get your regular (main) session. Also, the mouse and keyboard are shared between the two sessions / monitors.</div><br />Here's how this looks like:<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgIhMFoyqJ4HOIo9ekkhWWhkZnxZx6Kqbe79OMRc51FDX1FzxQ7U_XJFA9-4AvYcJoSEBxx8IYN2GQK6VORmzOKPoUHneEYjQabfNovttvx24RlVE3RdT8NMLo2GI2iujlHIcQV6DHsFb67/s1600/dell-xps.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="180" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgIhMFoyqJ4HOIo9ekkhWWhkZnxZx6Kqbe79OMRc51FDX1FzxQ7U_XJFA9-4AvYcJoSEBxx8IYN2GQK6VORmzOKPoUHneEYjQabfNovttvx24RlVE3RdT8NMLo2GI2iujlHIcQV6DHsFb67/s320/dell-xps.png" width="320" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhhuSF1IFoGJIBYnPYbe02WfSXVRgq7-3Hy-V7Lmj9JetTP8u7y6Xw6FpJOkavi79N0kxrLT_XYHXits3kU6j31Q7qlx6cmw_CquMMxv5cvnx2L94_vnSSYzq-iU1JtyNKMXNavFrM24HIq/s1600/lxde-hdmi.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="180" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhhuSF1IFoGJIBYnPYbe02WfSXVRgq7-3Hy-V7Lmj9JetTP8u7y6Xw6FpJOkavi79N0kxrLT_XYHXits3kU6j31Q7qlx6cmw_CquMMxv5cvnx2L94_vnSSYzq-iU1JtyNKMXNavFrM24HIq/s320/lxde-hdmi.png" width="320" /></a></div><br /><div style="text-align: justify;">The first image above is from my laptop's screen (Dell XPS L702X which comes with Nvidia Optimus) while the second image is the separate LXDE session which is also running on my laptop, but is displayed on a TV connected via HDMI. As you can see, the first one is using the Intel graphics chip while the second one uses Nvidia.</div><br /><br />However, there are some things to consider when using this:<br /><ul><li style="text-align: justify;">the sound won't work (if you know a way to get it to work, please let us know in the comments!) through HDMI so you'll only get sound through your laptop's speakers</li><li style="text-align: justify;">you can't move a window from your current desktop to the monitor connected via HDMI. The only way to run applications on the device connected via HDMI is to either run it from its session menu, or by using "export DISPLAY=:8.0" (see the end of the post for more info on this). The mouse is however, shared between the two desktops.</li><li style="text-align: justify;">when loading the extra session, you may get double indicators / tray icons on your current (main) session. There is a way around this though (see the "tips" section at the end of the post)</li></ul><br /><br /><br /><h2>Get HDMI to work with laptops using the Optimus technology under Ubuntu using Bumblebee and Synergy</h2><br /><b>1.</b> <a href="https://wiki.ubuntu.com/Bumblebee">Install Bumblebee</a> if you haven't already.<br /><br /><div style="text-align: justify;"><b>2.</b> Unity doesn't work with Bumblebee (and I'm not sure if you can run two sessions using the same window manager without them interfering anyway), so you'll need to use a different desktop environment / session, like LXDE, XFCE and so on - use whatever you want. 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.
