x log file
Using the radeon option "DDCMode" "on" seems to cause it to DTRT... You're using xorg-x11-drv-ati < 6.6.2-4, aren't you. I'm 99% sure that I grabbed -4 to try last night -- I can double check when I get home Yep, definitely have -4 and need the option in the config I believe i'm seing the same problem in a slightly different incarnation. I'm on 6.6.2-4 too, but running on an IBM ThinkPad T42 with a ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]. If doing a clean boot all the way to X, the resolution is fine. Any later restarts of X, logout, runlevel changes etc. that would cause X to restart triggers the problem for me and I also end in 800x600. option "DDCMode" "on" does not work around this problem for me. But i checked the Xorg.0.log file for interesting info and it looks like X for some reason believes that I have an external monitor connected to the system (which I don't - for the sake of clarity :o)). But since there really is no monitor, practically all usable resolutions are "out of range" and we end in 800x600. To let X know that i really have no external monitor connected, I added: option "MonitorLayout" "LVDS, NONE" to xorg.conf and problem is now successfully worked around.

T42 problematic X log file
Both Jeremy's and my own log file have : (WW) RADEON(0): Failed to detect secondary monitor DDC, default HSync and VRefresh used The problem is further that this faulty detection is used to find a common mode for MergedFB - leaving us in 800x600. Jeremy, have you seen this recently? |
