Resolution external VGA

after searching this forum and editing my xorg.conf i still have a problem.

my external 19" widescreen tft won't work in its native resolution (1440x900)

executing in the terminal

Code:

xrandr --output VGA --mode 1440x900 --output LVDS --off

shuts the internal monitor down, the external runs on 1152x870
(which is not that good looking)

any ideas how to get 1440x900 working?
(with Linpus Lite)

 

Try adding a ModeLine for 1440x900. I was going to suggest adding it to the Monitor section of xorg.conf, but I have some vague recollection that Linpus re-creates some of its config files on boot. If that's the case you can add it by running the following from a terminal:

# this is just from memory, not on a Linux box atm...
xrandr --newmode "1440x900" <modeline>
xrandr --addmode VGA "1440x900"

As for the contents of the modeline - try google... or probing your monitor using either read-edid or ddcprobe (no idea if either is included in Linpus tho).

 

A bit late for an answer...but you need to change the Virtual line in xorg.conf to 1440 900 if you want to just use your external.
