[resending because I suspect something went wrong the first time, sorry if it's a duplicate] Hi, a few days ago I upgraded to the last 2.6.34 rc kernel and found that with KMS both the console and X were using a 800x600 resolution instead of my LCD display's native resolution of 1440x900 who was selected by default with 2.6.33 and previous kernels. 1440x900 also disappeared from the available resolution listed by GNOME display utility, and I could enable it again only with the xrandr command line tool. I tracked the problem to this patch, which causes the same issues also when manually applied to 2.6.33: apparently the kms radeon driver wrongly detects a TV connected to my card (I don't have one, only a LCD display connected to the DVI port) and forces the TV default resolution for all the outputs. Attached to the email the xrandr output I get with 2.6.33 and 2.6.34 and pasted after the actual text are the relevant portions of the dmesg output of 2.6.34. I'm using a Radeon RV370 card. Please tell me if you need other information. Best regards, Giacomo dmesg: [drm] Initialized drm 1.1.0 20060810 [drm] radeon kernel modesetting enabled.
