Ctrl-Alt Backspace: Kill X or change run level?
« on: January 04, 2009, 03:57:47 pm »

What actually is going on when I do Ctrl-Alt Backspace once a desktop is running --- am I killing the X server, or dropping down to the non-graphical run level? Or are both actually indentical?

thanks,
Howard in FL

I have no clue.  I do know that I was warned once on this forum not to use cntl-alt-backspace as it might damage my reiser file system.  So now I use htop to eliminate the offending program.  And Logout/Restart/Shutdown.

Since adopting this course, I have had no problems worth speaking of.

Ctrl-Alt Backspace kills the X server, think of it like a user initiated crash.
any open programs could lose data and you could possibly cause corruption.
It will not change your runlevel. If you started X from init 2 then you will go back there if you are in init4 (GDM/KDM) it will restart X.

thanks for the replies  ;D

... it might damage my reiser file system.

any open programs could lose data and you could possibly cause corruption.

Interesting ... is the potential loss due to file buffers not being flushed, in which case the file system would be ok, but bad data ... or could it actually corrupt reiser?
