X locking when switching back to console

Thanks to this great forum, I have finally got mostly everything on my laptop working in Slackware, I faught with the ATI driver for days. I got the ATI driver working after upgrading to kernel 2.6.10 and am currently getting over 4,500FPS in glxgears.

One problem remains. When I am in X I cannot go back to the console using CTRL + ALT + F1 for example, I get a black screen and my computer locks. I first thought it may have been a problem with frame buffer, so I recompiled my kernel without it, but the problem continued.

If I do not load the FGLRX driver before starting X everything works fine, I can switch back to the console without issues. This leads me to believe that there is a problem with the FGLRX driver on my system.

System Info:
Averatec 6100HS, P4 3ghz HT, 512DDR, Radeon Mobility 9600 M10
Slackware 10 current, Kernel 2.6.10, Xorg 6.8.1
Have a SIS chipset, kernel is compiled for sis_agpgart support.

I have patched the fglrx driver with the 2.6.10 patch before compiling it.

Below is my xorg config:

I wonder if it's a problem with using the external AGPgart kernel module instead of internal? I have tried using the internal, however it doesn't work right and ends up using the Mesa drivers.

I'm not sure where to even begin troubleshooting as the computer is locking up.. would any of the logs help me here?

Any advice is appreciated.

I ran into the same problem myself and I would take another look because it may turn out to be a framebuffer issue. Assuming you're using lilo, edit your lilo.conf file and comment out whatever "vga=" parameter that's active, then uncomment the "vga=normal" entry so it becomes active. Rerun lilo (/sbin/lilo as root) I can't promise that will solve the problem but it's worth a shot. Good luck with it -- J.W.
