The next items on my list are:
A) Try booting with "radeon.modeset=0". [Simple idea, but it didn't
occur to me until just now.]
[As mentioned in previous msg:]
Using "radeon.modeset=0" eliminates the pink line. This is not a
desirable solution, since I lose KMS and (on Evergreen) my virtual
terminals if I start X.
B) Pull the HD 5750 and install my HD 4850. The older card was working
perfectly with KMS (even with a KVM + Dsub connection!) before I bought
the new card to try out the Evergreen support. I can try VGA/Dsub, DVI,
and DVI-to-HDMI cables with the old card and see which permutations (if
any) cause the pink vertical line to disappear. If no pink line occurs
at all, then the problem would seem to be Evergreen related.
OK. Just swapped in the HD 4850 in place of the Evergreen card. Same
kernel (2.6.33 with drm-radeon-testing of 100223 [git 383be5d] merged)
and same DVI-to-HDMI converter cable. Result: no pink line.
The problem is with the Evergreen card only. This means some hardware
fault (doubtful) or something lacking in the current Evergreen support.
Please understand that none of these messages are a complaint. I am
actually ecstatic about all of the efforts of the people working on open
source driver support for ATI hardware. These messages are simply a
report about a problem I'm having using my new monitor with
drm-radeon-testing.
C) Try a real HDMI cable instead. I mentioned that I don't own one,
but one is in the mail and should be here early next week. :)
Will be a few days before I can test this. Until then, I'll probably
just leave the HD 4850 installed... and enjoy some 2D/3D acceleration
once again! ;)
Thanks,
Dave W.
