So, i can not run gpu tasks without running X even with installed catalyst drivers?
Is that true?

Yes, you require X-server to be able to detect a GPGPU under Linux.

Thanks, you saved me some hours of headache.
Is there a workaround to run gpu taks on a remote server?

e.g. vncserver

with a xstartup like this:

#!/bin/sh

xrdb $HOME/.Xresources
xsetroot -solid grey
xterm -ls -title "$VNCDESKTOP Desktop" &
dbus-launch startkde

instead of startkde you can use another desktop

I also installed X there and launched xdm, so X should be running now.
Boinc can not find ane useable gpu, according to event viewer

I am running debian 7, with boinc 7.2.47, catalyst 12-6+point-3

and have a Radeon HD 6350
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Cedar [Radeon HD 5000/6000/7350/8350 Series]

I got it to work if i give boinc a lohin shell, su to boinc and run startx.
But thats not really a permanent solution.
Just starting X via xdm for example wont help.
