Hi,
I'm tring to set up my notebook and external monitor to work in a dual-head mode.
This is the configuration I use:
Graphic card - intel
Monitor - Samsung T260HD
- 1920x1200 @ 60Hz
- HorizSync 30.0 - 81.0
- VertRefresh 56.0 - 75.0
- Point Size 0,2865 mm
And some configuration files:
Code:
gontek@hapi:~/pxx$ cat xorg.conf
# xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg

I'm wondering why this command doesn't give the expected result:
Code:
xrandr --output LVDS --mode 1280x800 --pos 0x0 --output VGA --mode 1920x1200_60.00a --pos 0x800
After that the Samsung monitore (VGA) works in 1920x1200 mode but the desktop screen seems to be scaled (from 1920x1200 -> 1680x1200).
I solved it using the scale options:
Code:
xrandr --fb 1920x2000 --output LVDS --mode 1280x800 --pos 0x0 --output VGA --scale 1.143x1.0 --mode 1920x1200_60.00a --pos 0x800
I got the fallowing error as well: xrandr: specified screen 1920x2000 not large enough for output VGA (2195x1200+0+800)
but is there any other way? I don't want to scale screen size twice or even three times when I watch movies in e.g. HD ready resolution (1280x768).
Anyone can help? I'm using debian testing distribution.
