Grab X11 input and create an MPEG at 25 fps with the resolution 800x600

Have you ever had to scp a file to your work machine in order to copy its contents to a mail? xclip can help you with that. It copies its stdin to the X11 buffer, so all you have to do is middle-click to paste the content of that looong file :)

That works in all softs, CLI or GUI... I don't want to waste time to all the time typing the same stuff . So, I have that command in my window manager shortcuts ( meta+l ). All the window managers have editable shortcuts AFAIK. If not, or you don't want to use it that way, you can easily use the xbindkeys soft. I you're using kde4, you can run : systemsettings then open "inputs actions" and create a new shortcut. For Gnome take a look there : http://www.cyberciti.biz/faq/howto-create-keyboard-shortcuts-in-gnome/ A more advanced one, with strings and newlines : xvkbd -xsendevent -text "---8<-----\nToday date is: $(date +%Y%m%d)\n---8<-----" For complicated or long paste, you can feed xvkbd with a file : xvkbd -xsendevent -file <file> You can simulate ^C ( control+c ) too or others combinations of keys : xvkbd -text "\C\Ac" There's no man page nor help ( On my Archlinux distro ), but you can see online doc there : http://homepage3.nifty.com/tsato/xvkbd/ Show Sample Output

Requires: imagemagick and graphviz On Debian systems, displays a graph of package dependencies. Works also with other image formats, like svg : apt-cache dotty bash | dot -T svg | display

i spent way too many hours trying to fiddle with /etc/X11/xorg.conf trying to hook up various external projectors. too bad i didn't know this would solve all my problems.

This will save your open windows to a file (~/.windows). To start those applications: cat ~/.windows | while read line; do $line &; done Should work on any EWMH/NetWM compatible X Window Manager. If you use DWM or another Window Manager not using EWMH or NetWM try this: xwininfo -root -children | grep '^ ' | grep -v children | grep -v '<unknown>' | sed -n 's/^ *\(0x[0-9a-f]*\) .*/\1/p' | uniq | while read line; do xprop -id $line _NET_WM_PID | sed -n 's/.* = \([0-9]*\)$/\1/p'; done | uniq -u | grep -v '^$' | while read line; do ps -o cmd= $line; done > ~/.windows Show Sample Output

This starts a very basic X session, with just a simple xterm. You can use this xterm to launch your preferred distant session. ssh -X john@otherbox gnome-session Try also startkde or fluxbox or xfce4-session. To switch between your two X servers, use CTRL+ALT+F7 and CTRL+ALT+F8.

I'm not sure what apt this is, but it seems to work on most X screens, an is useful for saving power, and not straining your eyes Show Sample Output

Requires consolekit (works in e.g. Ubuntu). Here x11-display is DISPLAY Show Sample Output

This command first determines whether a second screen is connected. If this is the case, it sets the screen's RGB gamma via xrandr. Useful for cheap or slightly defective monitors with a tint. In this example a yellowing/champagne color deviation is compensated for by decreasing the red and the green portion of the image.

a typical X11vnc command

Useful for window managers like i3. With a plugin like Mailbox Alert on can run this command each time a new mail arrives and it will be lighlighted by the window manager.
