Hi, thanks for the suggestion. I didn't removed the
proprietary drivers yet.

...you should try the openSource driver instead of fglrx.Maybe your card
isn't supported with all its features by the fglrx-driver.

There are two openSource drivers for ati cards availible: 1. "radeon"
and 2. "radeonhd". The first one is for older cards: => R100/R200
(Radeon 7000 – Radeon 9250) and R300/R400/R500 (Radeon 9500 – Radeon
X1950) class chips, the second one for all newer chipsets => R500 and
newer. I suppose you need the radeonhd driver

To determine which chipset is yours run:

"lspci -v | grep VGA"

In the output you can finds the chipset class of your ati card.

Remove the fglrx-driver by running "apt-get purge fglrx".
Install the openSource driver by running "apt-get install
xserver-xorg-video-radeonhd" and also "apt-get install
xserver-xorg-video-radeon" Additionally you can install the
radeontool-package by "apt-get install radeontool" to manage
backgroundlight etc.

Try this and report.
Additionally information about the openSource drivers are availible


After this you probably have to adjust your "/etc/X11/xorg.conf" (if you
have one)
in the section "device" The driver must be
"Driver" "radeonhd" (radeon).
If you don't have a /etc/X11/xorg.conf file and you need it because
something doesn't work as you expected you can "produce" an appropriate
xorg.conf file for your card  by switching to runlevel 1
and run:

"X -configure"

After this you'll find an "xorg.conf.new" file under "/root" with all
availible options for this card and driver.You can use this file for
further editing and finally copying it to "/etc/X11". But first try if
your card wasn't automatically configured during Boot-up.
