kernel module (fglrx.ko) may be missing or incompatible
According to /usr/share/ati/fglrx-install.log, the kernel module didn't compile
because the headers were missing for Xen kernel.
---------------------------------
Solution:
I installed headers for Xen kernel:
apt-get install linux-headers-2.6.32-5-xen-amd64 build-essential
It also works for normal kernel:
apt-get install linux-headers-2.6.32-5-amd64 build-essential
Installed ATI drivers for normal kernel:
./ati-driver-installer-11-10-x86.x86_64.run
For xen kernel, I compiled like so:
cd /lib/modules/fglrx/build_mod/2.6.x/
I added '#define COMPAT_ALLOC_USER_SPACE arch_compat_alloc_user_space' in
kcl_ioctl.c and ran
make -C /lib/modules/2.6.32-5-xen-amd64/build SUBDIRS=/lib/modules/fglrx/
build_mod/2.6.x modules
mkdir -p /lib/modules/2.6.32-5-xen-amd64/kernel/drivers/char/drm/
cp fglrx.ko /lib/modules/2.6.32-5-xen-amd64/kernel/drivers/char/drm/
depmod
modprobe fglrx
