Xorg vesa driver stopped working after kernel upgrade
 

Hi there,
I'm a firstposter, hope this is the right place to ask.
Excuse me if I'm verbose, I hope too much is better than too few.

I use Debian for a few years now (since Sarge was Testing), the Testing
distribution, regularly dist-upgrading it. I have an ATI Radeon X1300
graphics card, hence "vesa" driver in Xorg ("ati" and "radeon" don't
seem to work, will look into the proprietary ATI driver in the near
future). FWIW, I have an AMD Sempron PC, 512 MiB RAM, 1152x864x24bpp
screen mode.


All worked just fine on this box until a kernel update in Testing after
Etch, and it just works if I stuck with linux-image 2.6.18 486. With
later kernels (was it since 2.6.22?) when X starts it shows a black
screen, with a red pattern on top of the screen (depending on the screen
resolution, other patterns at 1024x768 for example, seems garbage from
console).


I'd say all my system is aligned with the current Testing distribution
except linux, and since later kernels support my USB wireless dongle,
I'm trying to keep the pace. I have installed just the basic linux-image
package, with no console framebuffer, logos and the like.


Any suggestion?
Thanks,
Salvo

Have you tried the radeonhd driver?

Aptitude install xserver-xorg-video-radeonhd

I'll try it this evening, thanks for the hint.

But, in any case, isn't it strange that just running a kernel newer than
2.6.18 makes *vesa* stop working?

I've just tried the radeonhd driver, and I experience a problem
similar to the vesa driver: if I boot linux 2.6.18 it runs fine,
but if I run a later kernel, such as 2.6.25, I see KDM with no text,
wrong colors, wrong mouse cursor and, if I manage to login in my KDE
session anyway, I just see the white background of windows of my last
sessions and a gray panel on bottom, on a black desktop.
I've dist-upgraded yesterday.

Since I've read Xorg 7.3 is able to figure out a default configuration
with no xorg.conf, I tried to delete it. Both tests have been run with
this default configuration. Here is the unified diff of the two
Xorg.0.log files:

I don't know why with 2.6.25 a different address is assigned to the
graphic card and if this could be the problem.
Look forward to any comment.
Thanks,
Salvo

Xorg vesa driver stopped working after kernel upgrade
 

Hi,
it seems I have solved the following problem, or at least I have found
a workaround.

Putting vga=870 (1280x1024x32bpp) in the kernel command line for
2.6.25 lets Xorg run flawlessly with the radeonhd driver.

Thanks to anyone who helped.
