The VESA driver only allows you to use 4:3 modes, with none of the nice
features (acceleration, power management) that the Evergreen hardware
has to offer.
The proprietary ATI fglrx driver only works with versions of the X
server before 1.7. What version of Debian are you using? What version
of the X server do you have installed? (Try 'apt-cache policy
xserver-xorg-core'.)
Open source support (via "radeon", but not "radeonhd") for Evergreen
cards has been starting to appear since February. Debian Sid has very
recent versions of the "radeon" driver (xserver-xorg-video-radeon, v.
6.13.0-1) which includes all of the X support made available so far
upstream; but you will really want a very new kernel if you want to take
advantage of kernel mode setting. The Debian Kernel Team has backported
a lot of DRM support from 2.6.33 into recent 2.6.32 kernels, and also
has made available experimental 2.6.33 kernels. (I'm actually using
2.6.34-rc3 compiled from upstream because some Evergreen specific
commits appeared yesterday which update Evergreen support, and I am
testing a Radeon HD 5750 card which I own.)
Some of this open source software has probably trickled into
Squeeze/testing by now, if you are not using Sid and don't want to move
to it.
I've tried to install the ATI driver from AMD's website but when I specify
fglrx in xorg.conf X doesn't launch, but the module loads.
dmesg | grep fglrx
[ 12.403952] [fglrx] module loaded - fglrx 8.71.4 [Mar 2 2010] with 1
minors
lsmod | grep fglrx
fglrx 2236840 0
Does anyone have one of these working @ 1920x1080 resolution?
Or maybe offer some pointers to help me get up to 1920x1080?
You need an old (pre-1.7) X server to use 'fglrx', and you have to make
sure to install kernel headers matching the same version of the kernel
you are using, for 'fglrx'. It's possible that ATI will release a new
'fglrx' this month (or next) which is compatible with X server 1.7.X.
(I haven't been using 'fglrx', though; I'm only interested in testing
the open drivers, and helping to get them to work. If you just want to
use the card in a normal way, you should probably try to get 'fglrx' to
work until more features are provided by the "radeon" driver later this
year.)
