As asked on #5 I tried to use this command: xrandr --output LVDS1 --mode 1024x768 and this one xrandr --output LVDS1 --mode 800x600
But when I launch these commands from a terminal, the screen goes black, I tried to wait for about 2 miniutes, but seeing nothing happen, I typed in CTRL+ALT+F1 and then CTRL+ALT+F7, doing this I get the resolution I typed in the command line ( 1024x768 in the first command an 800x600 in the second). But if I go back to 1366x768 using the monitor settings in system settings and try again to change to 1024x768 or 800x600 I get the same problem, the screen goes black for about 20 seconds and comes back to 1366x768. ** Changed in: gnome-control-center (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/840974 Title: configuration of external monitor on laptop does not work properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/840974/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
