Hello, As suggested in the Xorg.0.log to contact radeonhd@opensuse.org, here is some data on my attempt to run radeonHD driver on my Sapphire HD2400pro AGP video card. When starting X the screen is actually switching to graphics mode and my monitor control confirm it's running at 1280x1024 @ 85Hz However, screen is almost all white and I see a lot of lines flickering, after ctrl-alt-backspace most of the screen turned blue ?! Attached Xorg.0.log file using RadeonHD driver as well as ATI's fglrx driver. The rhd_conntest tool reported this: -------- rhd_conntest: version 0.0.2, built from git branch master, commit dbb073b8.. Checking connectors on 0x94C4, 0x174B, 0x0028 (@01:00:00): Load Detection: RHD_OUTPUT_DACA HotPlug: RHD_HPD_1 DDC: RHD_DDC_0 DDC Line[0]: Slaves: 60 62 64 66 68 6a 6c 6e a0 -------- BTW for some reason this card doesn't seem to support DDC (also WindowsXP failed to get any info on the attached monitor). Any help would be appreciated, or ley me know if I can do some debugging or testing. Thanks, Ruud Linders
