One, add a new resolution for the monitor

There are two tools to use: xrandr and cvt

1. Use CVT to add a new resolution, the following is to create a 1280x1024, refresh frequency of 60hz Resolution

[Email protected]:~$ CVT 60# 1280x1024 59.89 Hz (CVT 1.31m4) hsync:63.67 kHz; pclk:109.00 mhzmodeline "1280x1024_60.00" 109.00 1368 1496 1712  1024x768 1027 1034 1063-hsync +vsync

2. Add the above modeline with Xrandr to the display's resolution list

[e-mail protected]:~$ xrandr--newmode "1280x1024_60.00" 109.00, 1368 1496 1712  1024x768 1027 1034 1063-hsync +vsync

3. Use Xrandr to see the newly added mode

[Email protected]:~$ xrandrscreen 0:minimum x 960, maximum 16384 x 16384vbox0 connected 1280x960+0+ 0 0mm x 0mm   1024x768       60.0 +   60.0     1600x1200      60.0     1440x1050      60.0     1280x960       60.0*    800x600        60.0     640x480        60.0    1280x1024_60.00 (0x14d)  109.0MHz        h:width  1280 Start 1368 end 1496 Total 1712 skew    0 clock   63.7KHz        v:height 1024x768 start 1027 end 1034 Total 1063           Cloc K   59.9Hz

4. Add the mode with the Xrandr –add-mode command:

[Email protected]:~$ xrandr--addmode VBOX0 "1280x1024_60.00" [email protected]:~$ xrandrscreen 0:minimum x, current x 960, maximum 16384 x 16384vbox0 connected 1280x960+0+0 0mm x 0mm   1024x768       60.0 +   60.0     1600x120 0      60.0     1440x1050      60.0     1280x960       60.0*    800x600        60.0     640x480        60.0     1280x1024_60.00   59.9  

As you can see, the resolution of 1280x1024 has been added to the display's resolution list.

5. Set the resolution:

[Email protected]:~$ xrandr-s 1280x1024_60.00

It's OK.

6. Persistent memory This newly added resolution add the following statement to the ~/.xprofilexrandr --output VBOX0 --mode 1280x1024_60.00

Second, write xorg.conf, solve the problem of Ubuntu resolution is not adjustable

Under the/etc/x11 directory, create a new xorg.conf file and write the following

Section "Screen"
Identifier "Default Screen"
Subsection "Display"
Virtual 1280 1024
Endsubsection
Endsection

Save the exit, and then restart your computer. If you still don't see a full screen, you can select the appropriate resolution in system settings-display.
