Hi, currently only a part of this bug is reproducible. The error message does not appear anymore, but changing resolutions, enabling/disabling monitors etc. does not work. Whatever I do in this dialogue, absolutely nothing happens when I click "apply".
Changing resolutions etc. on the command line works well. My monitor setup is as follows: Screen 0: minimum 320 x 200, current 3200 x 1200, maximum 8192 x 8192 DVI-0 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 546mm x 352mm 1920x1200 60.0*+ 1600x1200 60.0 1680x1050 60.0 1600x1000 60.0 1280x1024 75.0 1280x960 60.0 1152x864 75.0 1024x768 75.1 60.0 832x624 74.6 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 DIN disconnected (normal left inverted right x axis y axis) DVI-1 connected 1280x1024+1920+0 (normal left inverted right x axis y axis) 376mm x 301mm 1280x1024 75.0*+ 60.0 1152x864 75.0 1024x768 75.1 70.1 60.0 800x600 72.2 75.0 60.3 640x480 72.8 75.0 60.0 720x400 70.1 I tried to produce the gsd-debug-randr.log, but didn't succeed (although I did a logout/login): philipp@pc-philipp:~$ ls -l gsd* -rw-r--r-- 1 philipp philipp 0 2011-10-22 16:43 gsd-debug-randr philipp@pc-philipp:~$ -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/863547 Title: Setting screen resolution fails with error message "null" Status in “gnome-control-center” package in Ubuntu: Incomplete Bug description: After upgrading from Natty to Oneiric, my second monitor was disabled on first login. I opened the resolution dialogue via the system menu and enabled it (both monitors and their resolutions were correctly shown in this dialogue). After clicking "apply", nothing changed but a popup box appeared saying "The chosen screen configuration could not be applied (null)". Obviously, changing the resolution should work (it did in Natty), and if it fails, the message should be more helpful than "null". I have a Radeon HD 4870 and use the usual radeon driver. Manually enabling the second monitor with xrandr led to a Compiz crash, but I'll file a separate bug about that if I can reproduce it.
