I have this issue on my Acer Extensa 5635G. Looking at the Xorg.0.log, it seems that the proper mode of 1366x768 at 60Hz is being discarded with this motivation:
Mode is rejected: This mode's horizontal sync end (1446) exceeds the horizontal total size (1437). After some experimentation, the fix (on my machine) was easy. Attached is my entire xorg.conf, the important line of which is the ModeValidation option. This disables the specific check that failed above. See the documentation for the nVidia driver for details. Note that I'm running driver version 190.42, but considering the nature of the problem, this may well apply to the older version pulled in by Jockey. ** Attachment added: "xorg.conf" http://launchpadlibrarian.net/36673713/xorg.conf -- NVIDIA® GeForce G 105M - 512MB, gives 6 screens, with nvidia drivers version 180 https://bugs.launchpad.net/bugs/483857 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers-180 in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
