Can't see OpenGL output after installing amd fglrx driver.
 

Just installed AMD fglrx 8.42.3 driver on my Debian system with XOrg 7.2 and 2.6.22 kernel, and got a strange problem.
After successful installation all windows with opengl output display no output at all, only a black screen, with no errors, as they are working properly. glxgears prints FPS number, Quake and Danger from the Deep reacts on my (blind) actions - but I can see no picture.
What's the matter? And how can I fix it?
P.S. My video card is Radeon1300 (R515 chip).

Never seen that issue before. Have you used a previous version of the fglrx driver on this machine that worked. If so then I would downgrade back to that one to see if it returns to normal. If it does then I would look into contacting the ATI Linux driver team to see if they are aware of this. If not then maybe they can get info from you on your setup. The newest driver should have support even for AIGLX which is now in 7.10 xorg. Maybe you need to upgrade Xorg to 7.10. If you move to 2.6.23 kernel tree you will have issue getting ATI to compile unless patched. I would stay in the 2.6.22 tree for now.

edit:
Forget the part about 7.10. You have 7.20 already.

You've checked Xorg.0.log, right? Is everything good there, no errors & no significant warnings? fglrxinfo is showing:

OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ...
OpenGL version string: ...

right? or does it say "Mesa"?


There was a problem with some of the Debian packaging scripts, the result of which was one of the symbolic links to libGL wasn't getting created. I'm using a "multilib" setup (which is essentially a 64-bit kernel with a complete 64-bit userland and a functionally complete 32-bit userland). On the 32-bit side, libGl.so.1.2 was installed, as was the symbolic link libGl.so (which -> libGl.so.1), but libGl.so.1 (which should have -> libGl.so.1.2) was created.

I created the link manually and every driver with which that was a problem worked fine from that point forward.

Unfortunately, official 2.6.23 support has been lagging in flgrx; there is no release level verion of the driver, currently, that will compile at all w a 2.6.23 kernel.

I've seen a few patches kicking around; the one that seems to be the most prominent will (usually) get the current drivers to build against a 2.6.23 kernel, that's about all they do.

Hopefully, there will be 2.6.23 support in the next version of the driver.

Hope that helps.

I have current kernel 2.6.23.1 with ati 8.40 driver working fine with 3d and dri. Some buggy issues with ati 8.42.3 though. it may only be card specific. Now dri does not seem to work with 8.42.3 when patched. Like Larry says just enough to get basic fglrx drivers working. I can use say 3ddesktop with the latest kernel and ati 8.40 driver but does not work under the 8.42.3. Have not tried to work any further into it yet. I would say the AMD/ATI team will get it working.

Never mind on post number 2 about xorg 7.10 you are running 7.2 which would be 7.20.
Sorry about that.

I'm not at liberty to discuss this to the extent that I'd like to, but I can tell you that there were a number of top priorities, all of which had to be "fixed yesterday" - AIGLX support, and 2.6.23 kernel support, and so on. And while a number of them were addressed (and some of them more or less dispensed with), there are only so many hours in a day.

That said, I would check back on the ATI/AMD web site when release time rolls around again later this month.

Ummm .. I was just wondering ... where can I get the ATI patches you are talking about so that I can successfully install the fglrx 8.42.3 driver into the 2.6.23.1 kernel?
(I'm on Slackware 12 if that matters).

Cheers if anyone can help :)
