Since 11.4 (?) we have the following info in the release notes (time to add
this to the official docs now--13.2 and later). Frank, please reassign as
appropriate:
Initializing Graphics with KMS (Kernel Mode Setting)
With openSUSE 11.3 we switched to KMS (Kernel Mode Setting) for Intel, ATI
and NVIDIA graphics, which now is our default. If you encounter problems with
the KMS driver support (intel, radeon, nouveau), disable KMS by adding
nomodeset to the kernel boot command line.
To set this permanently using Grub 2, the default boot loader, add it to
the GRUB_CMDLINE_LINUX_DEFAULT kernel default load
options line in your /etc/default/grub text file as
root and running the terminal command
sudo /usr/sbin/grub2-mkconfig --output=3D/boot/grub2/grub.cfg
for the changes to take effect. Else, for Grub Legacy, add it to the kernel
command line in /boot/grub/menu.lst, also done as root.
This option makes sure the appropriate kernel module (intel, radeon,
nouveau) is loaded with modeset=3D0 in
initrd, i.e. KMS is disabled.
In the rare cases when loading the DRM module from initrd
is a general problem and unrelated to KMS, it is even possible to disable
loading of the DRM module in initrd completely. For this
set the NO_KMS_IN_INITRD sysconfig variable to
yes via YaST, which then recreates
initrd afterwards. Reboot your machine.
On Intel without KMS the Xserver falls back to the
fbdev driver (the intel driver
only supports KMS); alternatively, for legacy GPUs from Intel the
"intellegacy" driver
(xorg-x11-driver-video-intel-legacy package) is
available, which still supports UMS (User Mode Setting). To use it,
edit /etc/X11/xorg.conf.d/50-device.conf and change
the driver entry to intellegacy.
On ATI for current GPUs it falls back to radeonhd. On
NVIDIA without KMS the nv driver is used (the
nouveau driver supports only KMS). Note, newer ATI
and NVIDIA GPUs are falling back to fbdev, if you
specify the nomodeset kernel boot parameter.
