Hi, folks,

I recently installed Slackware 12.0 on a new Thinkpad R61i. Shortly thereafter, I installed the 2.6.25 kernel, to get the Intel wireless drivers. Things work swimmingly, for the most part. The most critical problem I've come across deals with OpenGL.

Whatever OpenGL application I attempt to use (thus far) locks up my system. I can't exit X, I can't three-finger reboot. I just have to shut the system down. This happens when coming across the GL-enabled screensavers in xscreensaver, as well as other applications, such as the POV modeler.

I haven't tried disabling 3d acceleration yet; I may try that. But I'm kind of at a loss as to where else to start looking for symptoms and clues. If someone has some pointers as to where to start looking (nothing I can discern in /var/log/), I'd be appreciative.

Thanks,

Daniel

Did you re-compile and re-install your OpenGL driver (Nvidia or Ati proprietary driver)? Forgetting that after a kernel upgrade is a common cause of your symptoms.

I've had the same problem on a T21 since I first got it. Anything using OpenGL will freeze the system. It uses the savage driver:

01:00.0 VGA compatible controller: S3 Inc. 86C270-294 Savage/IX-MV (rev 13)

Don't know if your uses the same card but I've never got it to work for 3D.

Hi, AlienBoB,

Nope. I'll look into recompiling the intel driver for the X3100. For some reason, I thought that'd be in modules. I assume that intel_agp is working with agpgart to control the agp interface, and is not the actual video driver. However, I'm not sure *what* driving the video, then, given that I have direct rendering enabled.

Thanks for the note.

DO NOT RECOMPILE the intel drivers (never works for some reason...lol). Get/reinstall the xf86-video-i810-1.7.4-i486-1.tgz package.

Read this post

I pulled the source/x/x11 stuff, dumped the xf86-video-intel tarball in src/, did
...and then installed the resulting .tgz package in /tmp/x11-build/. Still freezing.

I've just pulled the i810 package, and will give it a shot. Thanks for the tip.

As I said: For whatever reason, it seems compiling the Intel drivers from source just doesn't usually work.

I've heard tell that I should uninstall the i810 driver to get the driver for the X3100 (GM965) to work correctly.

I think I might be running up against some issues with the 2.6.25 kernel, and my default kernel--the one that worked fine for quite a while before I compiled 2.6.25--won't boot correctly. So, I'm going to install Slackware 12.1, which uses the 2.6.24.3 kernel as the default, which includes the iw3945 firmware and drivers, and is apparently a bit less likely to cause conflicts than 2.6.25 might.

Thanks for the help, again.

Daniel
