I'm experiencing some interesting things when X starts. I have a dual-screen setup I recently upgraded to KDE4.3.1.
When X starts, KDM is showed on the side of the screen. It seems like it's cut off in the middel and my desktop can scroll to the side (like having a virtual desktop). When KDE starts, the display returns to normal, but the screens are cloned and the desktop size is exactly the resolution size. If I log out of KDE, kdm shows up split across my two monitors and when i log in KDE uses the screens like I had one with w*2xh resolution. I guess kdm is calling some XrandR functions when I log out, but how do I find out what and get it to do so at the start? I'm using the ati-driver for my Radeon HD 2400 XT Sorry if my description is a bit unclear. Regards Dirk
