Reprint Ubuntu Custom Desktop Resolution

To modify a custom-sized desktop screen resolution on a ubuntu14.04 virtual machine, use the command: Cvt,xrandr

0. First look at the resolution settings that are currently available: Xrandr-q

[email protected]:/home/xxx/desktop# xrandr-q
Screen 0:minimum 1 x 1, 1504 x 768, maximum 8192 x 8192
Virtual1 Connected primary 1504x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm

VIRTUAL5 disconnected (normal left inverted right x axis y axis)
Virtual6 disconnected (normal left inverted right x axis y axis)
VIRTUAL7 disconnected (normal left inverted right x axis y axis)
Virtual8 disconnected (normal left inverted right x axis y axis)

The red Part I marked, VIRTUAL1 device name, will be used later, maximum 8192 x 8192 maximum support resolution;

1, in the terminal input: CVT 1920 1080, shown as follows:

[email protected]:/home/xxx/desktop# CVT 1920 1080
# 1920x1080 59.96 Hz (CVT 2.07m9) hsync:67.16 kHz; pclk:173.00 MHz
Modeline "1920x1080_60.00" 173.00 1920x1080 2048 2248 2576 1083 1088 1120-hsync +vsync

The red part is used in the--newmode command, and can be copied directly.

2, next through the--newmode 、--addmode 、--output command can be completed, as follows:

[email protected]:/home/xxx/desktop# xrandr--newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1 088 1120-hsync +vsync
[email protected]:/home/xxx/desktop# xrandr--addmode Virtual1 "1920x1080_60.00"
[email protected]:/home/xxx/desktop# xrandr--output Virtual1--mode "1920x1080_60.00"

At this point, the screen resolution has changed.

3. View by XRANDR-Q command:

Xrandr-q

Virtual6 disconnected (normal left inverted right x axis y axis)
VIRTUAL7 disconnected (normal left inverted right x axis y axis)
Virtual8 disconnected (normal left inverted right x axis y axis)

The red part is the resolution I added, and the addition of 1504x768 is omitted.

4. If you want to set your custom screen resolution to be permanent, append the following to the ~/.profile file:

Vim ~/.profile

CVT 1920 1080

Xrandr--newmode "1920x1080_60.00" 173.00 1920x1080 2048 2248 2576 1083 1088 1120-hsync +vsync

Xrandr--addmode Virtual1 "1920x1080_60.00"

Xrandr--output Virtual1--mode "1920x1080_60.00"

: x save to exit.
