[Chromium-users] Chromium GLX problem at the slavenode: problem still there after fixing GLX

[Michelle C. <hap...@gm...>]

Hello, there,
First of all, I would like to thank Dale and Sean for your suggestions. I
downloaded MegaLib and installed it at my slave node. Now, I can run glxinfo
succesfully, glxgears command  generates a openGL window with spinning
gears. Command xdpyinfo | grep -i glx` gives NV-GLX


However, when i tried to run the demo atlantis at the slave node by typing:
python crdemo.conf atlantis &
it runs ok,
then i typed: crserver &
still shows: CR warning: oscarnode7: Render SPU: Display :0.0 doesn't
support GLX
CR warning: Render SPU: couldn't get a visual, renderspu_SystemInitVisual
failed
CR warning: Render SPU: couldn't create a window, renderspu_FindVisual
return NULL
CR error: Render SPU: Couldn't get a double-buffered RGB visual with Z!


I noticed that on one of my  chromium working slave node, xdpyinfo |grep -i
glx gives GLX, and NV-GLX.  Could the missing GLX cause the problem in the
above case?

BTW, i am using root account when typing these above commands.
