xrandr - force resolution in linux

xrandr.txt

Most netbooks including the Acer Aspire One (zg5) have a native screen resolution of 1024x600 which can be a pain with some applications that require 1024x768 minimum .. some setting dialogs also seem to be larger than the screen allows.

Well you CAN get Peppermint 4 (or any distro based on >= Ubuntu 12.10) to give you 1024x768

This should work for Peppermint 4 .. and possibly for a FULLY updated Peppermint 3 (I can't currently test it in Peppermint 3 .. Ubuntu 12.04 based distros *used* to need a patched version of xorg but I *think* the patch was added in ubuntuupdates)

Run this in a terminal:
Code: [Select]

xrandr --output LVDS1 --panning "1024x768" --scale "1x1.28"

you can go back to 1024x600 with:
Code: [Select]

xrandr --output LVDS1 --panning "1024x600" --scale "1x1"



Once you've tested that in a terminal AND IT WORKS .. if you want to autostart that at bootup ..

Run:
Code: [Select]

mkdir ~/.config/autostart

then:
Code: [Select]

gedit ~/.config/autostart/monitor-adjust.desktop

when an empty file opens, make it read:-
Code: [Select]

[Desktop Entry]
Name=Monitor Auto Adjust
Comment=Change LCD resolution to 1024x768
Exec=lxterminal --command xrandr --output LVDS1 --panning "1024x768" --scale "1x1.28"
Terminal=true

SAVE the file, and log off/on to test.

BE SURE to test it in a terminal first, because if anything goes wrong a reboot will put you back to 1024x600


[EDIT]

If you have any problems with the wallpaper not stretching .. try making the commands:
Code: [Select]

xrandr --output LVDS1 --panning "1024x768" --scale "1x1.28" && pcmanfm --wallpaper-mode=fit && pcmanfm --wallpaper-mode=stretch

and
Code: [Select]

xrandr --output LVDS1 --panning "1024x600" --scale "1x1" && pcmanfm --wallpaper-mode=fit && pcmanfm --wallpaper-mode=stretch


obviously adjust the "Exec" line in the autostart file accordingly.


You can even go nuts and go to 1152x864 if you wish.....

For 1152x864 the command would be:
Code: [Select]

xrandr --output LVDS1 --panning "1152x864" --scale "1.125x1.44"
