I just setup ubuntu 11.10 on Dell XPS 15z by following the instruction from here:
Current status/known issues for DELL XPS 15z?
Everything seems ok until the point I failed to run openGL on chrome: http://get.webgl.org
This is the step I follow to setup the machine:
1) Add bumblebee ppa
2) install nvida-current from restricted drivers
3) install bumblebee (remember to "sudo usermod -a -G bumblebee YOURUSERNAME" as said by the bumblebee readme)
4) install mesa-utils
6) try intel card with terminal command "glxspheres"
7) try nvidia card with terminal command "optirun glxspheres"
While the step 7 is success, but step 6 was failed with following error message:
Xlib: extension "GLX" missing on display ":0".
When I run "glxinfo|grep OpenGL", it prompts
"Xlib: extension "GLX" missing on display ":0"."
This is my /etc/X11/xorg.conf
Section "Device" Identifier "Default Device" Option "NoLogo" "True" EndSection
I have turned on webgl support for chrome as well.
Fairly new to this, how could I fixed this?
