Compiz gives "Checking for Xgl: not present."

[carloshiga]

Hi friends,

I have upgraded from Gutsy to Hardy and boot stucked at some point. To fix it I had to edit xorg.conf changing

Section "Device"
Identifier "Generic Video Card"
Driver "nvidia"
EndSection

to

Section "Device"
Identifier "Generic Video Card"
Driver "nv"
EndSection

After that I loged in with no problems. So I notice that my OpenGL screensavers are not working and when I tried to test desktop effects nothing happened. When I run

compiz --replace

I got

Checking for Xgl: not present.
No whitelisted driver found
aborting and using fallback: /usr/bin/kwin

I tried to reinstall nvidia driver using Envy but I got an error too. I tried to reinstall compiz and all related packages but it not solved the problem.

Can anyone help me with this??

I had the same problem. Just install Xgl. I wish I could tell you how I did it, but I can't remember...

I tried

sudo apt-get install xserver-xgl

but the package is already installed.

Re: Compiz gives "Checking for Xgl: not present."

If you're running the Nvidia driver, then you DON'T want XGL. So the message from compiz "no xgl present" is exactly correct. If you installed XGL, remove it.

The main thing you need to see is glxgears working. If glxgears works, then probably you can install compiz and configure it and it will work. If no glxgears, then you've got work to do to configure glx on your Nvidia card.

glxgears

gives me
