nVidia direct rendering... [SOLVED]

[jonrpick]

doing this:

glxinfo |grep direct



produces this:

Error: glXCreateContext failed



I have an nVidia G100 card. The drivers are loaded and functioning...

How should I proceed in order to get direct rendering working so I can use 3D desktop effects via compiz-fusion???

Thanks,

Try the suggestion in Leigh's NVIDIA How-To/Guide: blacklist the 'nouveau' kmod. And then re-build the kernel boot image as instructed.

Sorry, I've not been doing my homework... I thought nouveau was specific to F11. I'm running F10. does that matter?

[Hlingler]

Yes, you are correct: the "nouveau' kmod syndrome is specific to F11+.

What NVIDIA driver RPMs are installed? If this is the same machine that had the "vanilla" kmods instead of required PAE kmods, then: remove them ("vanilla" kmods) first, if you have not already done so. Re-boot. More if that fails, or if that's not the case....

I removed all the "vanilla" kmods before installing the PAE stuff...

OK: try Leigh's suggestion to add the extra PATHs to the "Files" section. Post current xorg.conf - if same as old one in other thread, try: remove 'Option "AIGLX" "on" '.

Also: fetch compiz-check and execute it as per instructions on web site: http://forlong.blogage.de/entries/pages/Compiz-Check

Adding the paths worked!

Here's the xorg file as it is now:

The NVIDIA driver seems to need a very specific road-map. Go figure. Glad it's fixed.

Thread marked '[SOLVED]'.

I will add that the nVidia configuration app is unable to save a new xorg.conf file. I clicked the "preview" option then just pasted it into a new gedit window, and saved that as xorg.conf. I did back up the old one.

That was prior to my last reboot--about 2 mins ago. Before it wouldn't save my resolution settings. Now it comes up as it should.

I'm slowly but surely getting this thing configured. Desktop effects and graphics drivers are a new world for me, as I've never had a decent enough GPU to merit installing special drivers.

Thanks for all the help.
