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. guillaume@guillaume-notebook:~$ lspci -v | grep -A 12 VGA 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Device 163c Flags: bus master, fast devsel, latency 0, IRQ 43 Memory at c0000000 (64-bit, non-prefetchable) [size=4M] Memory at b0000000 (64-bit, prefetchable) [size=256M] I/O ports at 5050 [size=8] Expansion ROM at <unassigned> [disabled] Capabilities: <access denied> Kernel driver in use: i915 Kernel modules: i915 00:16.0 Communication controller: Intel Corporation 5 Series/3400 Series Chipset HECI Controller (rev 06) Subsystem: Hewlett-Packard Company Device 163c -- 01:00.0 VGA compatible controller: ATI Technologies Inc Robson CE [AMD Radeon HD 6300 Series] (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Device 163c Flags: bus master, fast devsel, latency 0, IRQ 45 Memory at a0000000 (64-bit, prefetchable) [size=256M] Memory at c4400000 (64-bit, non-prefetchable) [size=128K] I/O ports at 4000 [size=256] Expansion ROM at c4440000 [disabled] [size=128K] Capabilities: <access denied> Kernel driver in use: radeon Kernel modules: radeon 01:00.1 Audio device: ATI Technologies Inc Manhattan HDMI Audio [Mobility Radeon HD 5000 Series] Subsystem: Hewlett-Packard Company Device 163c guillaume@guillaume-notebook:~$ 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"...
