Hi, I have problems to correctly configure my dualhead setup. I am using the default software of Opensuse 11.0. I have a laptop with a 1400x1050 (121 DPI) internal display and an external monitor with 1600x1200 (100 DPI).
I would like to have the following configuration: 1. If the external display is attached I want 1600x1200 with 100 DPI. 2. If there is no external display I want 1400x1050 with 121 DPI. Additionally I would like to rotate the external display if possible. How can I achieve this? I've tried the setup at http://wiki.debian.org/XStrikeForce/HowToRandR12. The xorg.conf is: http://www.pontohonk.de/example/radeon/xorg.conf.exp The resulting logfile is: http://www.pontohonk.de/example/radeon/Xorg.0.log.exp The problems are: 1. Only 1400x1050 are shown. There is no way to get the full virtual desktop on the external screen. 2. On some starts the display is flickering 3. The server uses 66 DPI. After lots of trial and error I got the following xorg.conf: http://www.pontohonk.de/example/radeon/xorg.conf with the following logfile: http://www.pontohonk.de/example/radeon/Xorg.0.log Here I can switch between 1400x1050 and 1600x1200 but: 1. The DPI settings do not change. 2. The laptop always starts with 1600x1200 even without an external monitor. 3. The visible screen cannot be rotated. The output of xrandr -o left X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 154 (RANDR) Minor opcode of failed request: 2 (RRSetScreenConfig) Serial number of failed request: 12 Current serial number in output stream: 12 xrandr --verbose gives me: Screen 0: minimum 1400 x 1050, current 1600 x 1200, maximum 1600 x 1200 default connected 1600x1200+0+0 (0x4d) normal (normal) 0mm x 0mm Identifier: 0x4c Timestamp: 28128 Subpixel: horizontal rgb Clones: CRTC: 0 CRTCs: 0 1600x1200 (0x4d) 74.9MHz *current h: width 1600 start 0 end 0 total 1600 skew 0 clock 46.8KHz v: height 1200 start 0 end 0 total 1200 clock 39.0Hz 1400x1050 (0x4e) 73.5MHz h: width 1400 start 0 end 0 total 1400 skew 0 clock 52.5KHz v: height 1050 start 0 end 0 total 1050 clock 50.0Hz Is there a way to solve the problems and get a usable setup? Where do I have to look? Greetings Christoph _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
