I have an embedded board with Ubuntu 12.04 LTS GNOME 3.4.1. With this board I am using LCD display 800x480 and HID resistive touchscreen. Everything works fine but I have a problem with some dialog windows - for example "System settings" - this box is bigger than my screen. It means that I can't see the lower part of this dialog box (Apply, save button and so on).
I tried this: How can I resize the System Settings window?
It looks cool but without success :(
Then I tried this:
In xorg.conf (in /etc/X11) I edited this:
Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" SubSection "Display" Virtual 1024 768 EndSubSection EndSection
then I ran
xrandr -s 1024x768 and it came back with the following error -
Size 1024x768 not found in available modes
I also tried:
xrandr --output default --fb 1024x768 --panning 1024x768
UPDATE: I found this (last post): How to detect and configure an output with xrandr?
so I ran this commnad to get the modeline of the monitor:
gtf 1024 768 60
The output of this command is:
Modeline "1024x768_60.00" .. some numbers .. -HSync +Vsync
After that I added new mode, add mode and change resolution:
xrandr --newmode "1024x768_60.00" .. some numbers .. -HSync +Vsync xrandr --addmode default 1024x768_60.00 xrandr --output default --mode 1024x768_60.00
and it did nothing. No change on the screen.
I also tried this after that (suggested by Ken Mollerup below):
xrandr --output default --rate 60 --mode 800x480 --fb 1024x768 --panning 1024x768
But that also did not work
