Thanks especially to David Airlie for his 'drm-radeon-testing' branch, and Alex Deucher for his introductory Evergreen support.
I tried a week ago, and when I got black screens I gave up too quickly and pulled the HD 5750, replacing it with my slightly older HD 4850. This time I also got a black screen, but (as before) Windows Vista works perfectly, so I know the hardware is not defective. As it turns out, I use a KVM device that allows me to switch between 4 machines using Dsub VGA connectors. There are no VGA connectors on this HD 5750, so I was using a DVI-to-Dsub converter that came with the card so I could continue to switch between machines. After logging in via SSH, and making sure I saved 'dmesg' and 'Xorg.0.log', I thought about that converter possibly messing up the situation. I turned the monitor off, plugged in a DVI cable, and rebooted. Voila! Working KMS! No acceleration, of course, but I'm just glad to see the ball toward open source Evergreen support starting to roll! Switching between X and VT works fine, as well. And (unlike last week) I am getting the proper 1920x1200 resolution for my monitor. I have copies of 'dmesg' and 'Xorg.0.log' for both cases: WITH and WITHOUT the converter. The "radeon" driver seemed to be able to read the monitor info just fine even with the converter, but somehow DRM couldn't do the same -- the black screen occurs when the kernel switches from BIOS VGA to KMS radeondrmfb, and running X doesn't overcome the problem. Is it too early with regard to Evergreen support to file a bug report? I wouldn't even know what to file the bug against: DRM in 'drm-radeon-testing', I suppose. Now, after several hard months of getting acceleration to work on my HD 4850, I have a hard decision to make: leave the HD 5750 installed (no accel), or replace it with the HD 4850 (lots of accel) until the next round of support starts to appear? Much thanks, Dave W. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
