Hi, I got a second monitor and have KDE running in xinerama big screen mode without problems. Most everything works great but every game that I tried was streched over both screens when in fullscreen and gets so unplayable for me.
Xinerama useflag is set and xinerama is loaded by X without error.
My card:
# lspci |grep VGA
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI
Barts PRO [Radeon HD 6800 Series]
I use the opensource drivers with KMS here.
# emerge --info |grep xinerama

Is there anything that can be done to fix this problems with fullscreen
games?
The best would be if I could configure X to use the monitors as seperate
screens 0:1 and 0:2 but when I try to configure this in Xorg.conf the
second screen is not found and both monitors are configured in clone mode.
This is the xorg.conf that I tried last, atm no xorg.conf is used at all.

I hope someone can help me.
