[Bug 650539] Re: Launching QT apps under Xinerama crashes Xorg : affects SpeedCrunch, KeePassX, Lucky Backup, Pencil, Stellarium, Skype, Google Earth, VLC, Konqueror, VirtualBox, Opera ...

[kion]

nVidia just released new stable version of drivers - 260.19.12.

Among other changes there're few following related to Xinerama:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* Enhanced VDPAU to fully support Xinerama.
* Fixed a bug in the X driver that prevented operation of Xinerama when using
     multiple NVIDIA GPUs from different major hardware generations
     on X with ABI 4 or greater.
* Fixed a bug in the OpenGL driver's Xinerama support.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This would probably (hopefully) fix an issue.

PPA with fresh nVidia driver builds is here:
https://launchpad.net/~ubuntu-x-swat/+archive/x-updates

Can anyone test? (I'm currently fine with old versions of xorg/xserver -
see my solution posted above, so do not want to break anything until i'm
sure it will help - but it would be nice if someone who still has this
issue can test new version of nVidia drivers and report if it helps to
fix an issue)
