Re: external monitor?

yesterday I upgraded my system

Now I've got a problem to get
an external monitor working.

Earlier with 'etch I had no problems.
It worked just by plugging it in.

I used a few hours reading other people's
posts about this problems and tried
tinkering this and that, but no solution.

My laptop is HP nx9500 and the
external monitor is a normal 'Compaq',
which worked ok. earlier with 'etch'.

Now the external monitor stops
when gdm starts.

Does anybody have a clue what to do.

Is there such a tool for reconfiguring
'xserver-xorg' so that I could use just one
tool to get it working?

I tried  "dpkg-reconfigure xserver-xorg"
a few times, but that is only reconfiguring
the keyboard and keymaps and stops there.

If I'll do it by hand,

what should I write
onto 'xorg.conf' to get the external
monitor  working with the same
rates as the internal display (, which
was the earlier case)?

Need I do something else
for some other files?

I tried a few times to do something
with/for 'xrandr', but it was
of no help.

xrandr does work on Lenny. We've got two laptops using it with no problems. Studying http://www.thinkwiki.org/wiki/Xorg_RandR_1.2 was really helpful, particularly understanding the 2048x2048 concept in the Virtual screen section.  With xrandr you keep your xorg.conf file to a minimum.

Obviously your mileage may vary but if it's any help, my xrandr command is:

$ xrandr --output LVDS --mode 1024x768 --output VGA-0 --mode 1024x768 --left-of LVDS.

I had to change VGA to VGA-0. You can find your own display types with:

$ xrandr -q

That's it, although in Xfce I have to log out and then back in again to get the extra widths showing in the desktop workspaces.

Hope it helps
