Comment 8 for bug 144322

Hello,

I'm using my PAL modeline to drive my TV directly over the VGA connector. When upgrading from Ubuntu Feisty to Ubuntu gutsy, this stopped working for me. The first half of the screen is shown fine, then there's a horizontal black bar and then the first half of the screen is shown again in the lower half of my TV set. I can tell that it's divided in the middle because I see half of the mouse pointer which is usually placed in the middle of the screen.

When I downgraded from xserver-xorg-video-ati-6.7.193 to xserver-xorg-video-ati-6.6.3, it started to work again. In an attempt to narrow down the cause, I got xf86-video-ati from git. I have 82 revisions left for testing, but I'll provide my interim results here:

Commit 2618cf2aa8ed76411b943eb90c95869814c2f151 from May still works
Commit 0abce69f0d826a7ca1a41d963cd4730b6e01c145 from April is broken

I didn't use git-bisect for that because I'd keep hitting revisions which wouldn't compile properly or exhibited other problems.

So, if anyone has a fix or knows which revisions might be interesting, I'd appreciate any input. If not, I'll give git-bisect another try tomorrow (with my narrowed-down set of revisions this time).

Thanks,

Michael
