using an older thinkpad x40 and karmic and having this same problem. it seems Alessandro Arrichiello is correct and now i've got things working with compiz. the trick seems to be you have to settle for lowering the resolution so that neither width nor height sums to < 2048.
for example this won't work (except if screens stacked vertically): vga1: 1024x768 lvds1: 1024x768 this will work no matter how screens are positioned: vga1: 1024x768 lvds1: 800x600 i did not use the script above, i just made settings in System->Preferences->Display that followed the < 2048 rule. excuse me while i revel in my dual screen awesome. :-) -- karmic gnome-display-properties hangs for external monitor mode 1280x1024 https://bugs.launchpad.net/bugs/445100 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
