Проблемы установки драйверов fglrx в Debian Squeeze

dpkg: error processing fglrx-driver_8.632-1_amd64.deb (--install):
 trying to overwrite `/usr/lib/xorg/modules/extensions/libglx.so', which is also in package xserver-xorg-core
dpkg-deb: subprocess paste killed by signal (Broken pipe)

Решение:

dpkg-divert --package fglrx-driver --add /usr/lib/xorg/modules/extensions/libglx.so

mv: cannot stat `/emul/ia32-linux/usr/lib/libGL.so.1.2': No such file or directory
dpkg: error processing fglrx-driver_8.64-1_amd64.deb (--install):
 subprocess new pre-installation script returned error exit status 1

Решение:

ln -s /usr/lib32/libGL.so /emul/ia32-linux/usr/lib/
ln -s /usr/lib32/libGL.so.1 /emul/ia32-linux/usr/lib/
ln -s /usr/lib32/libGL.so.1.2 /emul/ia32-linux/usr/lib/

Проблема: 3D-ускорение не работает, 2D жутко медленное, glxinfo выдаёт не информацию о драйвере, а сообщение об ошибке. В Xorg.0.log имеются следующие строки:

drmOpenByBusid: drmOpenMinor returns -1

Причина: несовместимость драйвера с libdrm2 версии 2.4.12 и выше.

Решение: установить libdrm2 версии 2.3.1 (из Lenny).
