Dual View (:0.0 and :0.1 displays)

[laludelala]

Hallo!

I have a ThinkPad A31p notebook.
I want to have two displays running independently from each other. One on :0.0 and one on :0.1 - so I can run two independent desktops, the mouse beeing "jailed" in each.

To achieve this, I had two device, two screen and two monitor sections.

Since an update some time ago, my configuration does not work any more.
It seems this is because of xrandr support.



Any hint how to get the old behaviour back?



Saluti!

It should work again with xf86-video-ati version 6.8.0 or newer. ^.9.0 is probably a better bet as some additional zaphod bugs were fixed since 6.8.0.

Hallo!

So I should move from Xorg to XFree86?

No. xf86-video-ati is part of xorg. The ati driver shipped with xfree86 is ancient.

Hallo!

This is what it tells me in the Xorg.0.log
---
(II) LoadModule: "radeon"
(II) Loading /usr/lib/xorg/modules/drivers//radeon_drv.so
(II) Module radeon: vendor="X.Org Foundation"

But this is the package I have installed

you should be fine. configure zaphod multi-head the same way you used to (two device/screen sections, etc.)

Hallo!

Actually, I have the Zaphod-configuration running, but I only get the same image on both heads.

Actually, since the monitor on the 2nd head has a lower resolution than the primary one, it shows only one part of the desktop the primary one displays completely.


I have two device-, two monitor- and two screen-sections. And the server layout has one "Screen 0" and one "Screen 1" entry.

can you pastebin your config and log?

Hallo!

My xorg.conf (actually, the 2nd head is disabled):

http://paste.debian.net/14227/

And the logfile when starting with 2nd head enabled:

http://paste.debian.net/14229/

As You can see in the pastebin, it seems like if the LVDS panel was detected as DVI-0.


Anyway, the result is in having :0.0 screen only, LVDS turned off and the VGA-0 activated.

In your case, since you system has LVDS, DVI (probably on a docking station), and VGA, it's ending up with DVI and VGA for each zaphod head. You'll have to force the connector table to get this to work. If you want to use LVDS and VGA, add this option to each device section:

Option "ConnectorTable" "0,0,0,7,96,1,0,1"
