By the looks of it (and there's no much to look at so I could be wrong) you're on a Nvidia system using the xorg-edgers PPA.
Even if you're not on that PPA, it seems possible that you've updated the Nvidia graphics driver recently and haven't yet rebooted. When you update the driver module it isn't automatically reloaded into the kernel. To do that you would need to shut down X, rmmod
and modprobe
for it (and in my experience that doesn't even work for the deb-installed Nvidia driver, only the manual install.
The fix is really simple though. Restart the computer.
Your computer should load the new copy of the Nvidia module on boot and then everything 3D should just work™ again.
As this is a Bumblebee-using computer, it might be enough to close anything using 3D then run:
sudo rmmod nvidia
sudo modprobe nvidia
But as I say, this doesn't work on normal computers with the deb installer for the driver. Not sure why but it's worth a shot. Otherwise: reboot.
This might actually be far more TBP-related than I originally thought. Here is a support thread suggesting that something needs renaming.
I think the suggestion involves editing /etc/bumblebee/bumblebee.conf
so that
KernelDriver=nvidia-current
and then running sudo restart bumblebeed
to restart bumblebee.
