View Full Version : [ubuntu] compiz (core) - Fatal: Root visual is not a GL visual

April 9th, 2011, 02:05 AM

Getting the following errors. It's a 64bit laptop that was preinstalled with windows 7, but I had to roll back to XP and I'm dual booting Ubuntu 10.10.

desktop effects could not be enabled

Xlib: extension "GLX" missing on display ":0.0".
compiz (core) - Fatal: Root visual is not a GL visual
compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :0.0

Thanks for any help in advance,

Found this compiz check program:


Gathering information about your system...

At least one check had to be skipped:

You're using open-source nvidia drivers (aka nouveau), and the ones included with Maverick aren't current enough to support 3D on your card. Either install nvidia binary driver or update your kernel/graphics stack: https://launchpad.net/~xorg-edgers/+archive/ppa

Not positive how do complete your recommendations.

Also, I wasn't getting the "desktop effects could not be enabled" error the first time I installed ubuntu. (this is the 2nd time I've installed ubuntu) Trying to figure out what changed.

The easiest way is to go to System -> Administration -> Hardware Drivers and install the nvidia proprietary driver.

This is what I ended up doing and it worked for me. Installed a fresh copy of ubuntu 10.10 64bit edition.

installed compiz from link below

sudo apt-get install simple-ccsm compiz-fusion-plugins-extra compiz-fusion-plugins-main compiz-plugins emerald

Did smart update via command line
sudo apt-get update
sudo apt-get dist-upgrade

I have the same problem. Could you guys please give some more information? Do you know what the error means? So do you mean it is a problem with the driver?

I did apt-get install fglrx fglrx-amdcccle for my ATI driver, but I don't see anything in the proprietary driver menu.
