Description Chris Rankin 2009-05-20 13:27:01 UTC

I have just tried the latest git build of xf86-drv-ati and the cursor is not being rendered in the correct place on the screen. (There is a rectangle of corruption where the cursor hotspot is.)

The latest commit that works is:

commit 1429133ffdbfe046249fcaaa4cbee432a1012e55

    EXA: Set new EXA_SUPPORTS_OFFSCREEN_OVERLAPS flag when we have a 2D engine.

so it's probably this commit which is the culprit:

    Pre-atom: Improve engine clock setup code
    
    Also remove SetMemoryClk() for pre-atom cards for now
    as it requires quite a bit more asic specific work.
    To set the mclk we'll need to use the mem reset/dll tables
    in the bios.

This is my graphics card:

Are you using any of the new power management options?  Please attach your xorg log and config.

Xorg.0.log from session with screen corruption

I rebuilt the driver from scratch first, and the problem was still there. So I'm confident it's not a build error.

xorg.conf file

Additionally, when I rebooted the machine after getting this problem, I noticed that my framebuffer console had been "shifted"/"rotated" a few characters to the left.

Specifically, there was a column of text saying "StartingSt" down the RHS of the screen. Similarly, all of the "Starting sendmail" etc messages from the init.d scripts had had the "Starting" part removed.

Comment 4 Alex Deucher 2009-05-25 08:20:38 UTC

Changing the engine clock on r1xx does not work reliably at the moment.

Corrupted screen caused by corrupted cursor

I have the same problem. I am using Ubuntu 9.04 with a git snapshot of the radeon driver from 2009-06-22.

The problems started after activating DynamicPM in xorg.conf. There is no cursor corruption till the monitor goes blank (xset dpms force standby) for the first time. After then the cursor corruption occurs. Sometimes the screen gets corrupted, too. On some positions, the cursor is correct, but on others it's corrupted.
