Hello all,
First sorry for my bad english (I'm French).
Since Ubuntu Jaunty, I have some problems with dual-head on my ATI HD4850.
The problem appears to come from RandR 1.2. Aticonfig can't use --dtop or desktopsetup when randR 1.2 is enabled.
Catalyst 9.5 doesn't resolve this issue.
I disabled RandR (with this line : EnableRandR12=SFALSE in the /etc/ati/amdpcsdb file, under the right section).
But --dtop options are no more available.
I finally successfully set the dual-head via : aticonfig --xinerama=on
It works, but xinerama is not perfect (the mouse is drawed on each screen.
Is there a good way to use --dtop options with catalyst 9.5? A way to use amdcccle to set screen 2 at right of screen 1, and screen 1 at left of the screen 2 as it was easy to do with Ubuntu Intrepid 8.10?
Thank you very much for your help.
