Question kill X = kill computer!

Using the full install off the slack 9 iso. When I kill X, (ctrl-alt-backspace) it causes the computer to power down. Not halt, or suspend, but a complete and instant loss of power.

I was initally having problems when I logged out (wm is KDE), but disabled the frame buffer and that seems to have gotten rid of that problem.

I'm running a Radeon 9700Pro and thinking it must just be a driver issue. Any thoughts? I'd eventually like to re-enable the frame-buffer mode (hey it's pretty), and definately like to keep X users from being able to bring the entire server down. Thanks in advance.

Hi jd243
Actually, the problem you mentioned is caused by the BIOS. I have the same problem. The BIOS interprets ctrl-alt-backspace as a command to switch off the computer. To kill X I have to switch to another terminal (if you're using GDM only 6 will be open, otherwise use ctrl-alt-Fsomething), ps -axu | grep X and then kill that process. it's the only way i've found. There are apparently settings in your BIOS that can stop the ctrl-alt-bkspace shutdown under APM options or something similar, but i could never get that to change anything, and i got sick of disk checks every subsequent boot. Anyway, its so rare you have to do it that it doesn't really matter.
Oops, i've just seen that you're wanting non-root users to be able to kill X. In that case, investigate the BIOS options for your system. sorry... hope i was some kind of help.

If you are using a SiS 645 chipset there is no fix for this. it is part of the chipset functionality

I think this is a problem with Xwindows 4.3 and Radeon Cards. If you go to the Xfree site and look at the change log this was fixed after Slackware 9.0 was released. One work around is to disable dri. If you want to keep dri for games you can open a terminal and execute a shutdown any number of ways from the command line safely. Bug is #981

Your other option is to wait till an update comes out in current or compile from the Xfree CVS

Lastly this patch from gatos is reported to fix the problem
