@Martin: I've got a NVIDIA Geforce 7900GS and experienced the same problems (resolution, refresh rate and keyboard layout changed) after activating the restricted driver so i did the steps in comment #9 (and rebooted after steps 1, 3 and 4).
After step 4 (+ reboot), the resolution and keyboard layout were still the same as after step 3 (so r-m hadn't messed up xorg.conf this time), but the refresh rate had changed. After installing Feisty: 60/75 Hz (which are the two modes supported by my screen) after using r-m the first time: 50/54 Hz + keyboard layout and resolution messed up after doing step 3: 60 Hz only after doing step 4: 50/54 Hz again (which is not the correct setting for my screen), but keyboard layout and resolution still O.K. ** Attachment added: "xorg.conf after step 4" http://librarian.launchpad.net/7030369/xorg.conf -- Restricted Driver manager changes keyboard layout and screen resolution https://launchpad.net/bugs/94549 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
