Comment 4 for bug 813809

I've investigate a little bit more this bug.

Actually, I haven't installed ATI proprietary driver. So I use only free drivers.

Here is the result of some command :

guillaume@guillaume-notebook:~$ glxinfo | grep enderer
OpenGL renderer string: Mesa DRI Intel(R) Ironlake Mobile

According to glxinfo, render is done by the Intel integrated card.

guillaume@guillaume-notebook:~$ grep /drivers/ /var/log/Xorg.0.log
[ 24.493] (II) Loading /usr/lib/xorg/modules/drivers/intel_drv.so
[ 24.519] (II) Loading /usr/lib/xorg/modules/drivers/vesa_drv.so
[ 24.540] (II) Loading /usr/lib/xorg/modules/drivers/fbdev_drv.so
[ 24.543] (II) Loading /usr/lib/xorg/modules/drivers/intel_drv.so

Here, no radeon or radeonHD driver is loaded.

Finally, lspci show the ATI graphic card and says : "Kernel driver in use: radeon"

What does it mean ? Does the ATI card is used or not ?

When I install proprietary driver, Catalyst says something like "no graphic card"...

I'm not sure this bug has really been solved : https://bugs.launchpad.net/ubuntu/+source/linux/+bug/727620 and https://bugzilla.kernel.org/show_bug.cgi?id=30052

I'm not a specialist... is it a Kernel bug ? or Xorg bug ? ....
