I just tried an experiment. I started my xfce4 session twice, once
with Driver "radeon":
(II) LoadModule: "radeon"
[ 4055.387] (II) Loading /usr/lib64/xorg/modules/drivers/radeon_drv.so
[ 4055.387] (II) Module radeon: vendor="X.Org Foundation"
[ 4055.387] compiled for 1.17.2, module version = 7.5.0
[ 4055.387] Module class: X.Org Video Driver
[ 4055.387] ABI class: X.Org Video Driver, version 19.0
and again with Driver "ati":
(II) LoadModule: "ati"
[ 4444.981] (II) Loading /usr/lib64/xorg/modules/drivers/ati_drv.so
[ 4444.981] (II) Module ati: vendor="X.Org Foundation"
[ 4444.981] compiled for 1.17.2, module version = 7.5.0
[ 4444.981] Module class: X.Org Video Driver
[ 4444.981] ABI class: X.Org Video Driver, version 19.0
I grant you that tonight I don't see any difference in behavior between
the two "Driver"s, but I did yesterday. But that was 24 hours ago when
the moon was in a different phase and my evil computer spirits were in
a bad mood, apparently.
As I said, I find this whole subject so confusing that I can't explain
anything about it, even to myself.
