I have a similar problem. I'm using external monitor (native res. 1280x1024) connected via DVI to my laptop (native res. 1280x800).
When I start GDM and login to the X without external monitor connected, everything is ok (both screens have their native resolution). When I start GDM, when the external monitor is plugged in, GDM detects wrong resolution (1152x864) and when I log to the X, the resolution is still 1152x864. xrandr -q detects my external monitor correctly, but sets the resolution to 1152x864 instead of 1280x1024. Running xrandr --output TMDS-1 --fb 1280x1024 doesn't help. The same goes for setting virtual 1600 1200 in xorg.conf. The only workaround I found is to unplug the external monitor before GDM starts and plug in the monitor after I log in to the X. I don't use dual screen, laptop lid is closed when I use external monitor. Any ideas how to fix this? Should I provide some more information (like xrandr -q or xorg.conf listing)? -- [Hardy] GDM starts with wrong display resolution https://bugs.launchpad.net/bugs/194552 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
