Enabling direct rendering
 
Hi all,
I a complete newbie to Linux and I'm having trouble enabling direct rendering.
I'm running Ubuntu Hardy Heron on my laptop, a Dell Inspiron 6000, with a ATI MOBILITY RADEON X300 PCI video controller.

I did some searching but couldn't find a definate answer.

When executing glxinfo | grep rendering I get this:
Code:
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)
Here I'm stuck, since I have no idea how to set LIBGL_DEBUG=verbose.

Can someone help me out? I bet the answer is quite simple...

wget 08-23-2008 06:56 PM
export LIBGL_DEBUG=verbose

Then you'll probably have to run glxinfo without the "grep" part or you'll probably cut out the extra output.

Which driver do you use for your card? Is it the proprietary catalyst one?

Tried it, nothing happened. No text, nothing.

I think I messed up my setting. When I type glxinfo | grep rendering I get this:
Code:
libGL: XF86DRIGetClientDriverName: 1.9.0 i915 (screen 0)
libGL: OpenDriver: trying /usr/lib/dri/i915_dri.so
libGL error: dlopen /usr/lib/dri/i915_dri.so failed (/usr/lib/dri/i915_dri.so: undefined symbol: _glapi_Dispatch)
libGL error: unable to load driver: i915_dri.so
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)

I'm a noob. What is proprietary catalyst and how do I check my driver?

To check what driver is in use, you probably should look at /var/log/Xorg.0.log near the middle. Or, just do

grep fglrx /var/log/Xorg.0.log

if it doesn't output anything, you're not using the catalyst driver.

As to how to install it on Hardy Heron, here's a pretty good explanation:

Good Luck!

Well, it didn't output anything...

Thanks for the effort, but it didn't work. I followed the instructions (twice) but I get the error mentioned at the end of the ATI-guide. I guess it's because I have a Radeon x300 and not the Radeon x1200 the guide is made for? I also didn't get any output after typing in sudo depmod -a. All steps before that were finished successfully.

So, still no solution. Help?

Did you reboot? What does grep fglrx /var/log/Xorg.0.log say now?

I reinstalled Ubuntu fully, so the problem is gone too. Still don't know what caused it, but I'm satisfied now. Thanks for the effort, guys.
