blacklisting a driver (module)

cccc · 05-11-2011, 06:49 PM

Hi

I have really problems with i915 driver (module) and my graphic card on squeeze with gnome.
There is a BUG and there is no any solution at the moment:

https://bugs.archlinux.org/task/17705

So I'd like to disable i915 driver from the startup and load i810 module instead:

Code:

# modprobe i810
# modprobe i910
#

BTW I've tried to create /etc/X11/xorg.conf file with i810 module for the video card, but it doesn't work, i915 will be loaded.

Code:

Section "Device"
	Identifier	"i810"
	Driver		"i810"
EndSection

Is it any other way to blacklist i915 completely from the startup, for example in /etc/modprobe.d/blacklist.conf?

I'm a bit confused, at one point you are talking about kernel modules and then you start talking about xorg drivers.

To blacklist kernel modules in debian you can put a line like

Code:

blacklist i810

in /etc/modprobe.d/blacklist.conf

I have no idea how to "blacklist" xorg drivers, instead you can explicitly specify the "Driver" in the "Device" Section of your /etc/X11/xorg.conf

Cheers,

Evo2.

I've tried to blacklist i915 kernel module in /etc/modprobe.d/blacklist.conf:

Code:

blacklist i915

but it doesn't work, after restart i915 will be still loaded.

Code:

$ lsmod | grep i915
i915                  216538  2 
drm_kms_helper         18341  1 i915
drm                   111264  3 i915,drm_kms_helper
i2c_algo_bit            3489  1 i915
video                  14557  1 i915
i2c_core               12739  5 i915,drm_kms_helper,drm,i2c_algo_bit,i2c_i801
button                  3578  1 i915

Is it the driver or Kernelmodesetting causing the issue?
