Package: x2goagent

When starting a new x2go session, the startup scripts modify the
LD_LIBRARY_PATH of all applications to include /usr/lib/nx/X11/Xrandr.
This replaces the system libXrandr with the NX/X2go  provided one.
Unfortunately, this breaks the xrandr utility:

echo $LD_LIBRARY_PATH
/usr/lib/nx/X11/Xrandr:/usr/lib/nx/X11/Xinerama:/usr/lib/nx/X11

xrandr
xrandr: symbol lookup error: xrandr: undefined symbol: XRRGetScreenSizeRange
zsh: exit 127   xrandr

this was done to work around a critical Ubuntu KDE bug in precise:
https://bugs.launchpad.net/ubuntu/+source/libx11/+bug/985202

The path add-on for Xrandr is only done for KDE sessions. I will be happy to revert that nasty hack, but before that, we need someone to dig into KDE and (if I recall correctly) the patches applied to libxfixes in Ubuntu 12.04 and beyond.

If you disable the LD_LIBRARY_PATH code for Xrandr (x2goruncommand), then you will find regularly kwin crashes on KDE in precise+.

Greets,
Mike
