Unplugging the external monitor without disabling it from xrandr can cause problems.
type: xrandr and you will see a list of the connected outputs: LVDS, VGA, TMDS, TV (note: the names may vary). The external screen should be represented by either TMDS or VGA while your main screen should be LVDS. Before you unplug the external screen just type this to disable it: xrandr --output name_of_the_output --off and of course you will have to replace "name_of_the_output" with the name of the output. For example: xrandr --output VGA --off then, if xrandr doesn't complain, you can unplug the external monitor. -- Resolution wrong on laptop when unpluging external monitor https://bugs.launchpad.net/bugs/232087 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
