I recently upgraded some debian installations to the currently newest Version (wheezy).
While most of the upgrades went very smooth, I ran into some trubles updating a system running on a Intel Atom Board.
As I reboted the mentiond system to boot the new kernel the VGA signal droped.
In the end it seems to be a bug in the 'gma500_gfx' module witch caused the Graphic-Blackout.
After blacklisting the mentiond modul, it worked again as it should.
Recently i blogged about how to get a process list if you aren’t able to fork any processes . Also a process list is allways handy, i allways find cat a very usefull tool too. But as you might have noticed cat is not a shell builtin. So everytime cat is called a new process needs to be forked. In case you can’t fork processes it’s a problem, and even if you can fork them you may save resources by “creating” a shell builtin cat.
So lets do this,
open your .profile for usage with your user only or /etc/profile for global usage (You may also use your .bashrc or .zshrc instead).
Append the following lines to the file:
#pseudo bash builtin cat function
function cat { echo “$(< $1)" }

Sometimes i don’t want to put my macbook air asleep because of some job that is running. But i have to leave the room so i need to lock it.
So there is a shortcut for locking the screen:
Shift+Crtl+Eject
This works on the most macs, but the macbook air has no Eject button on the Keyboard. So on systems without an Eject button you have to use:
Shift+Crtl+Power
