Two displays with different resolution are joint
-
Install arandr
sudo apt-get install arandr
-
Run xrandr.
If your chosen resolution exists (regardless of which monitor it appears by) then skip the next step
-
If your resolution does not exist, create it by doing the following:
-
In this example the resolution I want is 1280x1024 cvt 1280 1024. This will create a modeline like this:
"1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync
-
Create the new mode:
xrandr --newmode "1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync
-
-
Add the mode (resolution) to the desired monitor (VGA-1):
xrandr --addmode VGA-1 "1280x1024_60.00"
Run arandr and position your monitors correctly
- Choose 'layout' then 'save as' to save the script
-
I found the best place to load the script (under Xubuntu) is the settings manager:
xfce4-settings-manager
OR
Menu -> Settings -> Settings Manager -> Session and Startup -> Application Autostart
If you have also take problem must comment me.....:)

After the last update, I am having this problem with two monitors resolution:
GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._gnome_2drr_2derror_2dquark.Code2: could not set the configuration for CRTC 63
I can see how
nvidia-settings
just detect one screen with with a resolution equal to 3286x1080 which is 1366 + 1920 (I have two screens 1366x768 of my laptop and 1920x1080 of an external monitor). The problem appears in the second screen. I can see 1/3 of the left part on the right size of the screen.Edit: If I run
xrandr
display:Screen 0: minimum 8 x 8, current 3286 x 1080, maximum 16384 x 16384 LVDS1 connected 1366x768+1920+0 344mm x 193mm 1366x768 60.0*+ 1360x768 59.8 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected HDMI1 connected 1920x1080+0+0 509mm x 286mm 1920x1080 60.0*+ 1680x1050 59.9 1280x1024 75.0 60.0 1440x900 59.9 1280x960 60.0 1280x800 59.9 1152x864 75.0 1280x720 60.0 1024x768 75.1 70.1 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 640x480 75.0 66.7 60.0 720x400 70.1 DP1 disconnected VIRTUAL1 disconnected
Also I noticed that the refresh rate to the second screen is very low.
