[Wine] Counterstrike Source: Monitor turns off when starting

[LukasW]

Hi all, 
ive just installed wine1.3 on my kUbuntu 10.04 to check if CS:Source is running on my system - and it doesnt, as usual.

When i start CS:S in fullscreen, my Monitor turns off (no signal) and my terminals on F1-F6 are just black. The monitor is not to bring on again, the only thing i can do is to reboot by login into ssh from another machine or press the power button to turn off.

When i start CS:S with parameter "-startwindowed" everything runs fine - until i switch to fullscreen mode. 

Any suggestions?

My System: 
wine 1.3.0 beta
kUbuntu 10.04
Intel Core2Duo E8400 / 4GB
ATI HD4830 with fglrx 2:8.723.1 (newest from ubuntu repo)
