I have found that the display output on the LVDS screen on my 19" iMac (model 7,1) has a garbled display. The DVI output for my 2nd monitor seems to be fine. This has been a problem with the Radeon driver for a while and does not occur with the RadeonHD driver. It also seems to occur with the latest 6.12.4 version of the radeon driver (which I pulled from the Debian Experimental repositories). My graphics card is an ATI Radeon HD 2600.
Please attach your xorg log, xorg config, the output of lspci -vnn fr your video card, and a copy of your video bios. To get your video bios (as root): cd /sys/bus/pci/devices/<pci bus id> echo 1 > rom cat rom > /tmp/imac.rom echo 0 > rom

Does xf86-video-ati from git master work any better?
I have just compiled the latest version from git (http://cgit.freedesktop.org/xorg/driver/xf86-video-ati/commit/?id=f082b1693d6f7f763ccf5a8436a89890ca2c6129) and it appears that now I get no display at all from either my LVDS or DVI screen. X.org just displays a blank screen. Looking at the X.org log it seems to be starting ok though (I can attach the x.org log if required).
Can you try with the latest code from xf86-video-ati git master? I just committed some new PLL code that might help.
Hey, that seems to be working! Thats great! Not sure if this is caused by the changes, but there is a performance issue now, dragging windows for example seems to be slow and stuttery, but at least I can see what is on the screen now! Thanks for your hard work!
Make sure acceleration is enabled. If you are still having accel problems open a new bug for that issue.
