Error while quitting X in Slackware 12.1

Tkdrg · 07-10-2008, 03:15 PM

I've installed slackware 12.1 yesterday and it worked as expected. After some tests everything was working. When I tried to exit X with Ctrl-Alt-Backspace to change my WM, the system crashed and I could only see a totally black screen ( no it isn't bash, it is totally black ). Anything else do not show any problem. The same computer with Slackware 11 didn't have this error. Any ideas?

Hi,

Assuming your hardware is identical with both versions of slackware (11 & 12.1) , and it is still functioning correctly;
the only thing that comes to mind is a modified/different X configuration, or perhaps a change in video drivers (ATI/nVidia/...) you installed/configured.
What do your system and X logs write about the crash ?

Tkdrg · 07-10-2008, 04:25 PM

It is the same hardware, the same xorg.conf and the same driver with the same video. The X server logs the same as it logged in 11, too. The only difference is the crash. Maybe it is about software versions.

EDIT: Now I can't shutdown it by software on X. Only by pulling the energy cable from the PC. Everything is allright in console, so I can't see what's happening.

I think it's time for someone with more experience/knowledge to step in here, as I'm somewhat out of suggestions.
Only thing that comes to mind is perhaps running X with extra debug/verbosity flags and checking that output,
or perhaps modifying your xorg.conf to try and find the offending module/driver/option.

Hope this helps , and best of luck

I have the same problem when I try to use drivers from ATI. My vesa drivers work ok. Have you tried to disable DRI? Possibly glx too and see what happens.

Disable Ctrl+Alt+Backspace from Restarting X Windows and use GDM to select windowmanagers, by logout and login with gdm you can select an other wm.

And this line to your xorg.conf in the section "ServerFlags":

Option "DontZap" "yes"

and issue the command gdm on the commandline

(Slackware 11 was still using a very stable 2.4 kernel )

Tkdrg · 07-11-2008, 04:51 PM

Well, I've tried removing DRI and GLX, but nothing changed. I do not want to use login managers, I prefer using the console. Actually, I only use X for a few things, like playing some games or using Firefox (for flash, etc). I spend most of the time on the console. I'm testing the DontZap now.

EDIT: Now Ctrl-Alt-Backspace do not work, nothing happens. That was the idea?

That's what he meant.
But it sounds more like a console driver prob.
Can you boot into rl2 without anyprobs ?
Maybe add vga=normal to lilo.conf

Tkdrg · 07-21-2008, 09:28 AM

Well, I'm already using vga=normal. I think that it may have something to do with those drivers, since nethack, aalib, libcaca and svgalib are messing up my console.

heinblöd · 07-22-2008, 03:43 PM

But what happens when you boot into rl2, without having any X started?

symatic · 07-23-2008, 08:27 AM

This may not apply, but in -current they have a updated mesa driver 7.0.3 I would give that a try and see what happens. It does sound like a framebuffer issue, but like you said you do not use that. This is about all the advice I can give. Why are you using alt+ctrl+backspace?

Slackware does not use gdm, does not have gnome.

Tkdrg · 07-23-2008, 12:24 PM

Without X, the system works without any error. I only use X for playing a few games, most of time I use only the console, so I start and close X many times.

heinblöd · 07-23-2008, 11:21 PM

I had a similar prob when i used the open source ati driver. Everytime i switched back to console, the screen was black or sometimes scrambled.
I was gone with the closed-source ati driver .
What kind of Gpu do you have ?
If you use a ati or nvidia card maybe try another driver ,.

Tkdrg · 07-26-2008, 11:15 AM

I'm using an onboard SiS gpu.
