Bug#606604: xorg: High memory usage when setting "radeon, modeset=0" in /etc/modprobe.d/radeon-kms.conf
I tried to do a check with /proc/dri/0/gem_objects, but with "radeon
modeset" disabled it does not exist.
And i use htop for memory usage monitoring. Even if it displays not
actual memory usage of xorg, then total system memory usage is still
much higher with kms=0.
