I've just had something similar on Gutsy (updated as of 23rd September, it's a feisty upgrade done a few weeks ago) ona Toshiba Equium A100-306 (Intel chipset) that runs at 1280x800 on its internal LCD. After a reboot it had dropped back to 1024x768 - this may have been me editing the driver to intel from i810.
So I reconfigured with dpkg-reconfigure on the xserver-xorg and got it working having selected the resolution, and used a customer monitor (but accepted the defaults). However If I use the System->Administration->Screens and Graphics dialogue and select the Generic-> LCD Panel 1280x800 it lets me select some lower res (e.g. 1024x768) and higher res (1280x960) but not 1280x800. I've attached the Xlog and xorg.conf of my current (apparently working OK) X config from my dpkg-reconfigure. ** Attachment added: "Xorg log from a working 1280x800 session" http://launchpadlibrarian.net/9466904/Xorg.0.log -- Available resolutions incompletely set to 1024x768, 800x600, 640x480 https://bugs.launchpad.net/bugs/49827 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
