ati radeon : hangs between CTRL+ALT+Fx's

[Sebastian Glita]

Hi,

I removed all. Still hangs. I disabled Accel. No hangs. I enabled Accel and XAA. Hangs. I disabled RenderAccel and use EXA. No hangs... until now, again :(

What I am sure of is that xf86-video-ati 6.9.0 scrambles VGA output, so that forced me to use the version from git; with this, agpgart+radeon+drm kernel modules are loaded, which did not with 6.9.0, and I am sure that because of them the Xorg server hangs, except when enabling "NoAccel", when they are not loaded. The modules are loaded by libdrm package from git, I guess? As in: http://lists.freedesktop.org/archives/xorg/2008-October/039623.html ?

Also, there is a noise, probably the fan of the graphics display, which I did not here before 6.9.0 on the laptop !!! Booting another OS the noise resumes. i hope this does not become a support forum for "the other OS's windows' server" :) too...

Thanks -- S.

Try removing all of the options in your config and see if that helps.
Also, this option:
Option          "AGPFastWrite"          "1"
Will almost always cause problems.  Remove that.
