# Direct Rendering not detected

Hi everyone,

I have problems with my gnome3. I am working with fedora 18 in a dell xps with nvidia card. Before it was working pretty well but for some stupid reason I remove bumblebee and after that now I can ONLY log in with the Classic Gnome. After that, this message appears:

Warning: Direct Rendering not detected. Audio only mode enabled.


First, I think I reinstall bumblebee following this instructions: fedoraproject.org/wiki/Bumblebee Since running

 optirun glxgears -info


seems to work. I think I reinstalled it correctly. Then, I reinstall gnome-desktop (just in case) running:

sudo yum reinstall @gnome-desktop


and nothing else happen. Finally, this is what I got with

 algomez@adelle:~\$ glxinfo
name of display: :1.0
Error: couldn't find RGB GLX visual or fbconfig
Error: couldn't find RGB GLX visual or fbconfig


any ideas???

Well, it looks like removing bumblebee caused the direct rendering support to break. I'd have expected reinstalling bumblebee to fix it. Peek into /var/log/Xorg.0.log and check if there are any errors. Could be a missing module. Also check your yum history to see what pacakages were removed along with bumblebee when you removed it. See if undoing the transaction works?
