Description Trond Eivind Glomsrød 2002-11-27 08:38:15 UTC
01:00.0 VGA compatible controller: Silicon Integrated Systems [SiS] SiS630 GUI Accelerator+3D (rev 31) When you hit ctrl-alt-backspace to exit X, the system turns off (in a second, not the controlled shutdown way). The system runs 1024x768, 16 bpp and seems to work normally other than that.... even accelerated 3D works. All updates applied. XFree86-4.2.0-72 kernel-2.4.18-18.8.0
Comment 1 Michael Lee Yohe 2002-11-27 14:37:40 UTC
Is your system entering a suspend/sleep mode? In other words, if you turn your system back on - does it pop up back into X? Or does the system execute as if it's been powered off? Does your XFree86.0.log contain anything useful? Does your /var/log/messages contain any kernel OOPSes or useful messages?
Comment 2 Trond Eivind Glomsrød 2002-11-27 14:46:10 UTC
No, the system is not just hibernating. Nothing in logs, or I would have written it. It just shuts off hard and immediately :) (Hah - I know you love broken hardware. Oh, and before you ask: No binary kernel modules. Pretty vanilla setup, too...)
Comment 3 Michael Lee Yohe 2002-11-27 15:01:09 UTC
Here's something you can do to isolate it within the driver for your video card. Override the video card settings configured for your system to use the basic SVGA X server. CTRL+ALT+BKSP to see if it sends your system spiraling into the abyss. That'll help Mike figure out where your problem is.
Comment 4 Trond Eivind Glomsrød 2002-12-02 09:45:16 UTC
Tested it last week with the vesa driver - same thing happens.
Comment 5 Mike A. Harris 2002-12-02 11:30:49 UTC
Hi Trond, Could you attach your config file, and the log from the X session that conks out, as well as /var/log/messages Could be DRI related. I presume you probably tried disabling DRI already though. If not, try that to see if it goes away. Also try noaccel. If any of those options change anything, we can try some other things to hopefully narrow narrow it down. I've added Alan, as he is a big SiS fan. ;o) TTYL
Comment 6 Trond Eivind Glomsrød 2002-12-02 11:43:51 UTC
Better SiS than MediaGX... >:-> I've tried without DRI (obviously one of the first things I tried...), and it wouldn't have effected VESA anyway. Nothing interesting in any of the logs
Comment 7 Alan Cox 2002-12-02 12:29:10 UTC
ctrl-alt-backspace is a powerdown hotkey on some SiS boards/bios setups. I don't believe you can change that. I don't know if X lets you change the key combination
Comment 8 Trond Eivind Glomsrød 2002-12-02 13:22:16 UTC
Well, broken BIOSes are hardly the fault of X....
Comment 9 Mike A. Harris 2002-12-02 14:50:56 UTC
Good thing I added Alan. I've never heard of this SiS issue before so it could have sent me on a wild goose chase. ;o) /me owes Alan a nice pint of ale at OLS 2003 for this one Trond, there are plans for XFree86 to allow configuration of the various hotkey sequences that might get into 4.3.0, and might even be in it already. If you're up to it, give rawhide X a shot. If it isn't in currently, you can also rebuild the X server with modified hotkey manually. The code is somewhere in the hw/xfree86/common directory IIRC. Let me know if you need a hand fiddling with it, and I'll try to come up with some hack if it isn't currently configurable. TTYL
Comment 10 Trond Eivind Glomsrød 2002-12-02 15:05:46 UTC
I don't miss ctrl-alt-backspace as much as hate the system turning off in an unplanned manner, so configurable key combinations aren't going to help that much I'm afraid. Thanks, Alan.
Comment 11 Mike A. Harris 2002-12-04 22:40:20 UTC
Understood... Just thought I'd mention the configurable keys are now in CVS builds, however I haven't investigated how to configure them. Just thought I'd let you know in case it is of some use anyway. Take care, TTYL
