Dualhead with Xgl (NVidia) and Non-Xgl (old Matrox)

[thielmann]

I'm now using Xgl/Xorg with my AGP card (GeForce4 MX 420).

I found a old Matrox PCI card, which I'm trying to use with a second X-server (without Xgl), to run MythTV on it.

I red a lot of howtos and manpages, but it still doesn't work.

thielmann@diabolus:~ $ lspci | grep VGA
0000:01:00.0 VGA compatible controller: nVidia Corporation NV17 [GeForce4 MX 420] (rev a3)
0000:02:01.0 VGA compatible controller: Matrox Graphics, Inc.: Unknown device 050b

I tried then "X -configure" which created the following xorg.conf:

This doesn't work as expected, there's only one X-server started (on my AGP card).

I managed to start the second Xserver with: X :1 -config /etc/X11/xorg2.conf
with the following xorg2.conf:

But the problem is, that the second screen only shows content, when I switch to it (using Ctrl-F. If I switch back, the monitor shows a black screen. Same for the main monitor.

Any ideas?

Finally got it working (some rubbish in my xorg.conf...).

But when I try to start some programs on the second screen, i get:

thielmann@diabolus:~ $ xterm -display :0.1
xterm Xt error: Can't open display: :0.1

Which kind of rubbish you removed? I have the same problem but I don't even get the card displaying any image.

But when I try to start some programs on the second screen, i get:

thielmann@diabolus:~ $ xterm -display :0.1
xterm Xt error: Can't open display: :0.1

I guess you have to use:

thielmann@diabolus:~ $ xterm -display :1

since you have two X-Server.

Hello and welcome to the forums, bibodo!

If you are having any problems with Linux, please feel free to start a fresh thread of your own with all the details. This one is well over 5 years old, so I'm locking it down.

Thank you.
