Scrambled screen (Radeon HD 3650 + LCD tv over DVI->HDMI)
the screen in Linux is strange with my desktop pc:
AMD Athlon 64 x2 5400+
4 gigs RAM
Radeon HD 3650
LG3000 32-inch LCD tv connected through DVI->HDMI
The screen is somehow scrambled and it's very hard to read anything on the screen. Seems like the screen has different columns a few pixels wide: every other is at the same level vertically and every other "column" is some pixels off vertically. Hard to explain, but for example when moving the mouse horizontally the arrow seems to "dissappear" partially and then pops up at the next "column"... As I said, hard to explain. But something like that.
When booting, the texts are fine, but when the resolution is changed by the OS while entering the desktop, it goes bad. I found the display settings in Ubuntu and the resolution (as far as I could read the scrambled screen) seemed to be the correct one for my tv, 1360x768. I tried to change the resolution to something smaller and Ubuntu hung.
I've tried various Live CD's:
Ubuntu 8.10 32-bit and 64-bit, 8.04 32-bit & 7.10 32-bit
Kubuntu 8.10 32-bit
Fedora 10 64-bit
All have the same display problem. Any ideas? I'd love to get rid of Windows like I have with my laptop.
