Dual screen issue on ATI Radeon HD 3200
Hello. I Just get a dual screen laptop (Kohjinsha DZ) with an ATI Radeon HD 3200 card. It seems to have a little problem with the dual screen. Here's my xorg.conf file: http://pastebin.ca/raw/1737837 Here's xrandr output: http://pastebin.ca/raw/1732437 I run X then I enable the second screen with xrandr: $ xrandr --output DVI-D_1 --right-of PANEL Then everything is fine, except that the right screen (just that one) is kind of blur. It's like if columns were missing. If I type "Hello world!" in a terminal, I can see something like "Hlowrd". Here's some pictures (screenshots are, of course, fine): Original: http://nyquil.org/uploads/IndianHeadTestPattern16x9.png Picture of my Kohjinsha: http://img709.imageshack.us/img709/2240/indiantest.jpg Perfect quality DivX: http://img31.imageshack.us/img31/2571/divxy.jpg cat /etc/services: http://img13.imageshack.us/img13/1877/catetcservices.jpg I use X.Org X Server 1.6.5 and radeonhd 1.3.0. I tried radeon (second screen not detected) and fglrx (X freezes at startup). Do you have any idea?

Wow. Never seen something similar. Looks like there are 8 correct pixels, then 8 pixels skipped, pattern repeats.
Do you have any idea?
Please try
Option "AccelMethod" "shadowfb"
in the Device section of xorg.conf. Maybe this is acceleration
dependent. Though I doubt so.
Also, what happens if you configure both monitors to show the same image
(cloned mode)?

I just tried "shadowfb", it didn't work.
The problem is exactly the same in clone mode, the right screen remains buggy.
Without X launched (and without any framebuffer), the right screen is
perfectly readable. So it's not a hardware problem.
