Undistract-me Notifies You When Terminal Commands Are Completed

<div style="text-align: justify;"><b><a href="http://mumak.net/undistract-me/">Undistract-me</a> is a simple tool that notifies you when a command you run in a terminal which takes longer than ten seconds to finish is done.</b><br /><br />Besides letting you know that the command has finished running, the notifications sent by Undistract-me display the command you ran (useful if you run multiple commands in the same time) and the number of seconds it took for the command to finish.</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">This can be useful e.g. when you start to compile something and then you switch to some other window to read your emails or whatever and get distracted and forget about the command you ran: Undistract-me displays a notification when the command / job you ran in the terminal is done so you can go back to the terminal and see the final result, etc.</div><div style="text-align: justify;"><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="http://2.bp.blogspot.com/-2Jcyk-sJOac/UPFpoEgr5KI/AAAAAAAAMnQ/e9nw7-kOP18/s1600/undistract-me-notification-update.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="command completed notification" border="0" height="161" src="http://2.bp.blogspot.com/-2Jcyk-sJOac/UPFpoEgr5KI/AAAAAAAAMnQ/e9nw7-kOP18/s320/undistract-me-notification-update.png" title="command completed notification" width="320" /></a></div><br /><a name='more'></a><br /><div style="text-align: justify;"><b>There is another way of doing this: using an "alert"</b>, about which we've <a href="http://www.webupd8.org/2010/07/get-notified-when-job-you-run-in.html" title="Get Notified When A Job You Run In A Terminal Is Done, Using NotifyOSD [Ubuntu]">written a while back</a> (or a simple notify-send command added after the actual command you want to run) - which by the way is now available by default in Ubuntu, simply use "some command; alert". <b>However, using the "alert" alias, you must add "alert" at the end of each command you want to be notified for and you may forget to do this sometimes</b>, while using Undistract-me, this is not required and any command that takes more than 10 seconds to complete will trigger a notification.<br /><br /><b>Undistract-me only works with Bash (default in Ubuntu) and should display notifications on any desktop environment</b> - here's a GNOME Shell screenshot:</div><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/-fuJcsscl2rw/UPF5gObhAwI/AAAAAAAAMoo/UJTTNp1p0f8/s1600/undistract-me-gs.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="undistract-me notification GNOME Shell" border="0" height="207" src="http://4.bp.blogspot.com/-fuJcsscl2rw/UPF5gObhAwI/AAAAAAAAMoo/UJTTNp1p0f8/s320/undistract-me-gs.png" title="undistract-me notification GNOME Shell" width="320" /></a></div><br /><br /><b>By default, Undistract-me notifies you when any command that takes longer than 10 seconds to complete is done, </b>so you don't get flooded with notifications for simple commands like "ls" or "cd",<b> but you can change this: </b>edit the <i>/usr/share/undistract-me/long-running.bash</i> file as root and changing the "LONG_RUNNING_COMMAND_TIMEOUT=" variable value from 10 to whatever you want.<br /><br /><div style="text-align: justify;">Update: in a later release, Undistract-me  has added a "LONG_RUNNING_COMMAND_CUSTOM" variable which you can use to send a command other than "notify-send".

Fix Wireless Or Wired Network Not Working After Resume From Suspend In Ubuntu

<div style="text-align: justify;"><b>It's time for another fix, this time for wired / wireless network not working after resume from suspend</b>. In Ubuntu, sometimes when resuming from sleep, the wired network doesn't work and I keep getting "disconnected" notifications. I've read that some users are having similar issue with the wireless connection but for me, it's always the Ethernet connection.</div><br /><a name='more'></a><div style="text-align: center;"><a href="http://img.netupd8.com/network-ubuntu.png"><img alt="Ubuntu network" src="http://img.netupd8.com/network-ubuntu_thumb.png" /></a></div><br /><div style="text-align: justify;">So here's a fix that has worked for me, under Ubuntu 12.10 (but it probably works with other Ubuntu versions as well as other Linux distributions).</div><br /><br /><h2>Get the wired / wireless network to work after resume from suspend in Ubuntu</h2><br /><div style="text-align: justify;"><b>1.</b> <b>To fix the Ethernet / WiFi network not working after resume from suspend</b>, firstly, you must <b>find out the kernel module used by your network hardware</b>. The <a href="http://www.techytalk.info/ubuntu-fix-network-stopped-working-after-resume-from-sleep/">article</a> where I've found this fix suggests using the following command:</div><pre class="linux-code"><code>sudo lsmod</code></pre><br /><div style="text-align: justify;">and then trying to figure out which module is the one used by your network interface. But that's not so easy to do, so here's an easier way. Firstly, <b>install "lshw"</b>, a tool to list your computer hardware - in Ubuntu, install it using the following command:</div><pre class="linux-code"><code>sudo apt-get install lshw</code></pre><br />Then, to <b>list the network interfaces</b>, use the following command:<br /><pre class="linux-code"><code>sudo lshw -C network</code></pre><br />The command output should look more or less like this:<br /><pre class="source-code"><code> *-network <br /> description: Wireless interface<br /> product: Centrino Wireless-N 1030<br /> vendor: Intel Corporation<br /> physical id: 0<br /> bus info: pci@0000:03:00.0<br /> logical name: wlan0<br /> version: 34<br /> serial: 4c:85:93:2d:34:61<br /> width: 64 bits<br /> clock: 33MHz<br /> capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless<br /> configuration: broadcast=yes <b>driver=iwlwifi</b> driverversion=3.5.0-22-generic firmware=18.168.6.1 latency=0 link=no multicast=yes wireless=IEEE 802.11bgn<br /> resources: irq:51 memory:f3b00000-f3b01fff<br /> *-network<br /> description: Ethernet interface<br /> product: RTL8111/8168B PCI Express Gigabit Ethernet controller<br /> vendor: Realtek Semiconductor Co., Ltd.<br /> physical id: 0<br /> bus info: pci@0000:0a:00.0<br /> logical name: eth0<br /> version: 06<br /> serial: 00:e0:3c:64:00:08<br /> size: 100Mbit/s<br /> capacity: 1Gbit/s<br /> width: 64 bits<br /> clock: 33MHz<br /> capabilities: pm msi pciexpress msix vpd bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation<br /> configuration: autonegotiation=on broadcast=yes <b>driver=r8169</b> driverversion=2.3LK-NAPI duplex=full firmware=rtl_nic/rtl8168e-2.fw ip=192.168.0.130 latency=0 link=yes multicast=yes port=MII speed=100Mbit/s<br /> resources: irq:53 ioport:2000(size=256) memory:f3004000-f3004fff memory:f3000000-f3003fff</code></pre><br /><div style="text-align: justify;">Depending on the network interface you're having problems with after resuming from suspend, look under "description: Wireless interface" (for WiFi obviously) or "description: Ethernet interface" (for wired network) and <b>under "configuration" you should see the kernel module used by that interface, as "driver="</b>, as you can see in the above example output (in bold). In my case, it's "r8169" (for RTL8111/8168B PCI Express Gigabit Ethernet controller).</div><br /><b>2.</b> The next step is to edit the <i>/etc/pm/config.d/unload_modules</i> file as root with a text editor:<br /><pre class="linux-code"><code>gksu gedit /etc/pm/config.d/unload_modules</code></pre><br />(the file may not exist in which case, an empty file will come up - that's ok)<br /><br />And inside this file, paste the following line:<br /><pre class="linux-code"><code>SUSPEND_MODULES="$SUSPEND_MODULES <b>MODULE_NAME_FOUND_UNDER_STEP_1</b>"</code></pre>replacing "MODULE_NAME_FOUND_UNDER_STEP_1" with the Kernel module name for your network interface found under step 1, "r8169" in my case.<br /><br />Example:<br /><pre class="source-code"><code>SUSPEND_MODULES="$SUSPEND_MODULES r8169"</code></pre><br /><div style="text-align: justify;">Then, save the file and that's it. Now even if the wireless / wired network wasn't working, if you set your computer to suspend, after resume the network should work.</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">Note: tested on Ubuntu 12.10 64bit with a <a href="http://www.amazon.com/gp/product/B0052F35I2/ref=as_li_tf_tl?ie=UTF8&tag=weup07-20&linkCode=as2&camp=1789&creative=9325&creativeASIN=B0052F35I2">Dell XPS 17</a> L702X with Ethernet not working after resume from suspend.

The issue isn't limited to those who are using a SSD, but it's a lot more frequent when booting Ubuntu from a solid-state drive.</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">I too am experiencing this issue with Ubuntu 12.10 (not tested on older Ubuntu versions because I didn't have a SSD when I was using 12.04) and I've found <b>two possible workarounds which have worked for me so I thought I'd share them with you, in case you're experiencing the same issue</b>.</div><br /><a name='more'></a><br /><div style="text-align: justify;">It seems that the black screen with only a blinking cursor (though sometimes I've also seen the "System is running in low-graphics mode" error) issue occurs due to a race condition with LightDM and without any tweaks, the only way to load the desktop was to either switch to a tty (CTRL + ALT + F1), login and then restart Lightdm using the "sudo service lightdm restart" command or restart the computer. So here are two possible workarounds:</div><br /><br /><br /><b>1. Start LightDM with a delay</b><br /><br /><div style="text-align: center;"><a href="http://img.netupd8.com/lightdm-ubuntu12.10.png"><img alt="LightDM" src="http://img.netupd8.com/lightdm-ubuntu12.10_thumb.png" /></a></div><br /><div style="text-align: justify;">One way around this is to start LightDM with a delay. My system, with Ubuntu 12.10 64bit installed on a SSD boots in ~14 seconds so adding a 2 second delay isn't much, however, for some, a larger delay might be needed (it depends on the system / SSD). This isn't ideal but it's definitely better than having to manually start LightDM or restart the computer. </div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">I must also mention that from what I've read, this workaround doesn't always work, meaning that if before using it, LightDM wouldn't start 50% of the time, using this workaround doesn't necessary mean it will work 100% of the time. Since I've applied this tweak, LightDM has worked every time for me so this probably depends on the hardware / SSD and how fast the system boots.</div><br /><div style="text-align: justify;"><b>To start LightDM with a delay, edit the <i>/etc/init/lightdm.conf</i> file as root with a text editor (I'll be using Gedit below):</b></div><pre class="linux-code"><code>gksu gedit /etc/init/lightdm.conf</code></pre><br /><div style="text-align: justify;">And near the end of the file (line 47 for me under Ubuntu 12.10 with LightDM 1.4.0-0ubuntu2), <b>above "exec lightdm", add the following line and then save the file:</b></div><pre class="source-code"><code> sleep 2</code></pre><br /><div style="text-align: justify;">"2" is the number of seconds used to delay starting LightDM. Like I was saying above, "2" was enough for me, but depending on your system, you might need to add a higher value.</div><br />This is how the end of the <i>/etc/init/lightdm.conf</i> file should look like after editing it:<br /><br /><div style="text-align: center;"><a href="http://img.netupd8.com/lightdm.conf.png"><img alt="lightdm.conf delay" src="http://img.netupd8.com/lightdm.conf_thumb.png" /></a></div><br /><br /><br /><b>2. Use GDM instead of LightDM</b><br /><br /><div style="text-align: center;"><a href="http://img.netupd8.com/gdm-ubuntu12.10.png"><img alt="GDM" src="http://img.netupd8.com/gdm-ubuntu12.10_thumb.png" /></a></div><br /><div style="text-align: justify;">The issue did not occur for me while using GDM and booting Ubuntu from a SSD, so if you don't want to add a delay to LightDM, you can install and use GDM instead.</div><br /><b>To install GDM in Ubuntu, use the following command:</b><br /><pre class="linux-code"><code>sudo apt-get install gdm</code></pre><br />Or install it via Synaptic, Software Center, etc.<br /><br /><div style="text-align: justify;"><b>When installing GDM, you'll be prompted to select the display manager: here, select GDM instead of LightDM.</b></div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">If GDM was already installed but you were using LightDM, you can switch to GDM by using the following command:</div><pre class="linux-code"><code>sudo dpkg-reconfigure gdm</code></pre><br />And then select GDM when prompted.<br /><br />More about switching between LightDM, GDM, etc. in Ubuntu, <a href="http://www.webupd8.org/2011/07/how-to-switch-between-gdm-lightdm-or.html" title="How To Switch Between GDM, LightDM Or KDM In Ubuntu">HERE</a>.
