Hi *,

at work I just received a new display. As I have just
changed from crt to tft at home, I thought, I could do the
same at work.

At home I use a 19'' tft with 1280x1024 resolution. In
order to get more desktop space, I use xrandr to use the
lcd of the x31 and the tft in a dualview configuration:

 xrandr --output VGA-0 --right-of LVDS --mode 1280x1024 --rate 60

At the same time I've changed the Virtual setting in
xorg.conf to (1024 + 1280 =3D 2304):

 Virtual 2304 1024
=20
Everything works as expected. With a windowmanager, which
supports xrandr (xmonad), windows can be moved between
screens but can display different virtual desktops as well.

Now the problem: Changing the virtual line taking into
account the display size (1680x1050) of the tft at work, X
no longer starts. The virtual line in question is=20

 Virtual 2704 1818
=20
"X no longer starts" is probably wrong. Actually the lcd
of the x31 becomes dark, but if I look really close, I see
a dialog box (probably from gdm), but I cannot read the
error message.

Any ideas? Is there anybody out there, who uses an x31
with a 1680x1050 tft in a dualview configuration?

Thx for any hints.
