Title:
Dual monitor display does not work when secondary is on the left side
Status in nvidia-graphics-drivers package in Ubuntu:
Invalid
Bug description:
Hi guys,
KUbuntu 10.04 here, 64bit.
I have two identical NVidia cards GT 9400. I have set up XInerama and
both monitors are "up". Logged into KDE just fine. The secondary
display is physically located to the left of the primary display.
The problem is that if I want to move the mouse on the second screen,
as soon as it "gets" there, it starts a "Brownian motion" - it
literally jumps in all directions with a very high frequency although
all its movements are confined in a roughly 2 inches area. No matter
how much I try to move it to the left, it won't go beyond that
invisible margin (not that having it in the middle of the secondary
screen would help in any way given its oscillating behavior). I can
"drag it back" to the primary screen where everything is fine again.
Sometimes, not always and not sure exactly when and why, doing this
experiment and/or clicking in the secondary screen kills the X server
completely and I am back to the login step.
The interesting thing is that is if I configure the secondary screen
to be on the "right side", there are no problems - everything works.
Now I know I could physically move the secondary screen to the right
... but the LCDs are slightly different in size (22" versus 23") so it
would be great if I should not have to do that.
Likewise I guess I could swap the connectors/cables and thus the
monitors roles but the one that's primary now is a better monitor and
I need it for gaming ... :-)
If you need anything else let me know. Thank you for reading this !
Best regards,
Obi1
