Laptop monitor issue.

Link to this post 13 Sep 13

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
