And right now I'm using Ubuntu 9.10 64bit.
Having Ubuntu 9.04, openSuSe 11.1 and Linux Mint, and after the intallation of the Ati drivers (using the Hardware Manager either the manual installation) I was not able to setup a resolution of 1920x1080 in my monitor. Also for a reason unknown to me (and everyone else I asked) when I typed in the terminal "aticonfig" or "aticonfig --initial) the response was: "aticonfig: no supported adapters detected".
Not to mention the watermark in the down-left corner of my screen saying: "AMD Not supported hardware"
I just installed Ubuntu 9.10 Karmic Koala and what is changed is that the command "aticonfig" works!!! But the command "aticonfig --initial" does NOT!!! :'( :'( :'(
Also I don't get the annoying watermark anymore.
After I installed the FGLRX driver though the Hardware Drivers section my xornf.conf looks like this:
Identifier "Default Screen"
Identifier "Default Device"
Also I have to say that I have the same problem in Windows, only the problem is fixed when I install the Monitor Driver from Samsung. Before the installation of the monitor driver, the max reso I can have is again 1600x1200 but after that I can have 1920x1080. So I suppose that I have to force the monitor the reso I want somehow...
please, PLEASE, help deal with this really frustrating problem. Excuse my english and thank you in advance...
