[Thomas Antepoth <544496@xxxxxxxxxxxxxxxxxx>]

Situation here: Clean install of 10.04 Lucid Lynx with a current kernel
of:

2.6.32-24-generic #41-Ubuntu SMP Thu Aug 19 01:38:40 UTC 2010 x86_64

"lspci | grep VGA"

reports a

01:00.0 VGA compatible controller: ATI Technologies Inc RV610 video
device [Radeon HD 2400 PRO]

The setting of

GRUB_CMDLINE_LINUX="radeon.modeset=0"

in /etc/default/grub resolves the performance issues discussed here for
me but xrandr reports a max. screen resolution of 1280x1024 which is
nothing compared to the

   2048x1536      80.0*    75.0     75.0     60.0

at which X is running with KMS enabled right now. The proprietary fglrx
shipped with Lucid also had some issues regarding performance (resizing
windows) as well as screen resolution ("unable to read edid
information").
