Welcome to the Linux Foundation Forum!

Laptop monitor issue.


I'm not sure if this is in the right area but i have a question. Could someone explain to me how to setup any version of linux so that my 1366x768 resolution to run. right now the only way i can do that is to connect to an external monitor source. It boots and all but i cannot see login screen and i can't see the desktop without using external monitor which can be seen when using the external monitor to login. i was just wondering if there is a way that i can get this pc to just run otherwise because i honestly would prefer to run linux than windows 7 which is currently what i am running. i will probably run ubuntu because it just works.

    It sounds like your video card is sending incomplete data or something that is resulting in the autoconfigured Xorg configuration not working. You may have to manually configure the xorg.conf file(s). I recommend starting my checking the /var/log/Xorg.log.0 file for errors, writing a base xorg file from x and then customizing based upon the errors.

    May me wrong frequencies of GUI configuration tool set, had same issue using xfce-4. So me had to reset it using:

    Use xrandr command as follow and substitute <YOUR_MONITOR> with appropriate monitor name:

    Shows you available monitors:

    Enables output on monitor with highest resolution:
    xrandr --output <YOUR_MONITOR> --auto

    on my system eg.
    Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767
    eDP1 connected (normal left inverted right x axis y axis)
       1366x768      60.02 +
       1024x768      60.00  
       800x600       60.32    56.25
       640x480       59.94
    DP1 disconnected (normal left inverted right x axis y axis)
    HDMI1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 531mm x 299mm
       1920x1080     60.00*+  50.00    59.94  
       1680x1050     59.88  
       1600x900      59.98  
       1280x1024     75.02    60.02  
       1440x900      59.90  
       1280x800      59.91  
       1152x864      75.00  
       1280x720      60.00    50.00    59.94  
       1024x768      75.08    70.07    60.00  
       832x624       74.55  
       800x600       72.19    75.00    60.32    56.25  
       720x576       50.00  
       720x480       60.00    59.94  
       640x480       75.00    72.81    66.67    60.00    59.94  
       720x400       70.08  
    VGA1 disconnected (normal left inverted right x axis y axis)
    VIRTUAL1 disconnected (normal left inverted right x axis y axis)

    This would disable my built-in monitor
    xrandr --output eDP1 --off

    This enables my external monitor using HDMI:
    xrandr --output HDMI1 --auto
