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

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.

alias ssh-x='ssh -c arcfour,blowfish-cbc -XC'
xset fp+ /Applications/Mathematica.app/SystemFiles/Fonts/Type1/
x11vnc -rfbauth /etc/x11vnc.pass -o /tmp/x11vnc.log -forever -bg -noxdamage -rfbport 5900 -avahi -display :0

Functions: ps read

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

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.

xvkbd -xsendevent -text $(date +%Y%m%d)

Functions: date

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 :


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/

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.

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 :)
