Thanks, Alex. The kms-enabled radeon driver is only available in the
~.34 kernels, no?
Assuming that I were to pre-allocate a larger front buffer using a
Virtual directive in xorg.conf, how would I do that? Would this be
enough?:
Section "Screen"
Identifier "Default Screen"
Monitor "Generic Monitor"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1680x1050" "3360x1050" "1680x2100"
Virtual 3360 2100
EndSubSection
EndSection
The newer *buntus don't even have an xorg.conf file, and there are
some difficulties in getting it to read on that hte user puts in
there. I am basing my question on the content of this page:

Thanks.
