Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

I'm sure this belongs in another stack site, but I don't know which one.

Either way, I've been using Arch with dual monitors for a while, eventually, a system upgrade somehow ruined my video drivers, and I was stuck with only one monitor. I dealt with that for a while, but then it stopped booting. I love Arch but don't have the time.

I switched to Debian with Xfce, and can't seem to get the second monitor recognized, can someone point me to the right stack, or just give some help?

I managed to have this working on Arch, after a weekend of working, but was hoping Debian would be a little bit easier on me.

I can supply any more output. When I last loaded Arch, the CLI showed two monitors, but Xfce did not.

Thanks a million! I was about 1 day from delivering a friend a new simple business website (friend price -- free :)), he would also appreciate.

If someone tells me that Gnome will magically solve everything, I can reinstall, however I've grown to love xfce.

thanks!

Edit: I think the disconnect is that lspci sees the extra video card, while xandr doesn't...

1 Answer 1

I'm personnaly using the opensource nvidia driver with xrandr to handle my dual-screen.

THe only configuration is in my .xinitrc :

xrandr --output DVI-0 -s 3840x1080
xrandr --output DVI-0 --mode 1920x1080
xrandr --output DVI-1 --mode 1920x1080
xrandr --output DVI-0 --left-of DVI-1

You will probably have some modification to make it fit with your setup.

EDIT

In your home directory you have a .xinitrc file. This file is read by the startx command or connection manager like slim.

I don't know what connection manager you are using, but assuming you are using the startx command you have to edit your .xinitrc file and add the previous lines before you start xfce4.

Example of .xinitrc file I have on a archlinux box running xfce4 :

# ~/.xinitrc
#!/bin/bash

xrandr --output DVI-0 -s 3840x1080
xrandr --output DVI-0 --mode 1920x1080
xrandr --output DVI-1 --mode 1920x1080
xrandr --output DVI-0 --left-of DVI-1

exec startxfce4
