Dual monitor setup screwed after upgrade to jessie

[ReinerS]

Well, I still use this oldfashioned xorg.conf file for my two-monitor setup under the prop nvidia-driver:

Code Auswählen Erweitern

Section "ServerLayout"
   Identifier     "Layout0"
   Screen      0  "Screen0" 0 0

It works fine with kde. Xfce has the, earlier mentioned, trouble.
Only Problem I have currently with X is that it doesn't (again) handles my PS/2 Logitech Trackman FX right. It used to work just without any entries in xorg.conf but has stopped since a while. I have to look deeper into that as I remember some issue with vmmouse but am not sure what it was.

I wonder if adding an input device to xorg.conf would help?

Code Auswählen Erweitern

Section "InputClass"
   Identifier   "Logitech Trackball"
   MatchProduct "Trackball"
   Option       "ButtonMapping"      "1 8 3 4 5 6 7 2 9"
   Option       "EmulateWheel"       "True"
   Option       "EmulateWheelButton" "9"
   Option       "XAxisMapping"       "6 7"
EndSection
I got that from the Arch wiki.

input devices are not handled by xorg any more, or am i wrong?


ReinerS, have you tried to cut down the configuration file to just the relevant things only by removing extensions, server layout and files sections?

[ReinerS]

Yes, input devices are normally handled by xorg itself.
Therefore I had removed all input entries quite a while ago and it had worked quite well until a week or two ago.

To taylor the xorg.conf I used the at that time current one and removed all for input relevant entries. My PS/2 Logitech Trackman Marble FX worked then with all buttons.

Well,
while fiddling around with my new installation I experimented again with xrandr, Xfce and nouveau.

For the moment it looks like I have succeeded to configure XFCE/xrandr with my dual-monitors as I wanted it to behave.

One big 3200x1200 framebuffer with two monitors with phys.resolution each and each of them panning in an area of 1600x1200  
The actual command for that has been:

Code Auswählen Erweitern

xrandr --fb 3200x1200 --output DVI-I-1  --mode 1280x1024 --panning 1600x1200 --pos 0x0 --output DVI-I-2  --mode 1280x1024 --panning 1600x1200+1600+0 --right-of DVI-I-1

I hope it stays that functional !!
