Hey, Where's the Xfce panel restart option?

If the "Restart" option is missing from the "Action Buttons" on the Xfce panel, read below to get it back.

The restart option is missing in the left photo.

Fix

Open a terminal window and enter these two lines:

xfcommand="xfconf-query -c xfce4-panel -p /plugins/plugin-9/items"
eval $xfcommand"$(eval $xfcommand | tail -11 | sed 's/-restart/+restart/' | awk '{printf " -t string -s %s", $1}')"

Alternatively you can right-click the "Action Buttons" item on the Xfce panel and select properties.

And enable the "Restart" option on the following window.

[FIX] Enable wireless in Xubuntu 12.04

In Xubuntu 12.04 when I boot my laptop with the wireless switched off and then try to switch it on while the system is already running, won't work.

I click on the network indicator plugin and it says that wireless is disabled by hardware switch, which isn't true. Luckily the solution is quite simple.

Fix

Open a terminal window and run:

sudo rfkill unblock all

Install Tex Live 2011 in [X]Ubuntu

LateX is a collection of many tools so a few LateX distributions were created to make it easier to find and installed them. For Linux there are two main distributions: Tex Live and teTeX. Since teTeX is declared obsolete^[1], Tex Live is the better option.

Ubuntu 12.04 Precise Pangolin ships with the old Tex Live 2009. Below the installation process for the never version, Tex Live 2011, is described.

Install

There are several ways of installing Tex Live:

• Get Tex Live on DVD (more information)
• Installing TeX Live over the Internet (more information)
• Downloading one huge ISO file (more information)
• Downloading several big tarballs (more information)
• Mirroring/downloading the TeX Live repository (more information)

I'll describe the installation method with the collection ISO, because is the one I found to work better.

1. First download the texlive2011.iso from a nearby: CTAN mirror.

2. Mount the iso image using this command (adjust the path to iso):

   sudo mount -t iso9660 -o ro,loop,noauto /your/texlive2011.iso /mnt

3. Still in the terminal, navigate to the mount point and run install-tl:

   cd /mnt && ./install-tl

4. Now a menu will be presented with options to configure the installation. For example, use 'D' to change TEXDIR (installation directory), 'C' to select collections (if disk space is not a problem I advise to install them all) and 'L' to select language collections. Use 'I' to begin installation.
5. When installation is completed, add the directory TEXDIR/bin/x86_64-linux to your PATH and that's it, Tex Live 2011 is now installed!

Safely remove USB drive from command line

You can find the device name using the mount point (replace MOUNT_POINT with the appropriate mount point, eg, /media/disk):
