Hello everyone,

I just experienced a crash while making some panoramas in Hugin. After opening
a project file in Hugin all I need to do is go to the "Crop" tab, grab a corner
of the crop rectangle and move it around for a few seconds and the X server is
sure to crash, taking me back to the login screen.

Looking into logs I see:

[845880.808] (EE)
Fatal server error:
[845880.808] (EE) WaitForSomething(): select: Invalid argument
[845880.808] (EE)

Please consult the The X.Org Foundation support
         at http://wiki.x.org
 for help.
[845880.808] (EE) Please also check the log file at "/var/log/Xorg.0.log" for
additional information.

I'm not sure whether it is related, but going through Google, I found some ~2
year old discussions:
https://lkml.org/lkml/2012/8/31/1

or suggestions to upgrade to a newer synaptics driver (Jessie seems to be using
1.6.2, which may be perhaps causing some problems? See
http://lists.x.org/pipermail/xorg/2013-May/055680.html ).

I'll try to include the project file and photos I'm using to reproduce this
thing.

Thanks and best regards,
Martin

It seems I was looking at Wheezy by mistake, Jessie uses
xserver-xorg-input-synaptics version 1.8.1 of course. So the problem is
probably not directly related to whatever may have been solved by the
synaptics upgrade.

Hi again,

I have another piece of (hopefully useful) information:

1) I was apparently not using the "right applications"; I just found out
that launching basically any 3D application causes xserver to crash
instantly. Easily reproduced e.g. by launching glxgears.

2) Also, I found out that it happens ONLY if I have an external display
connected (via HDMI, the laptop has no other reasonable outputs
available). The external display is set up by:
  xrandr --output HDMI1 -r 85 --mode 1024x768 --right-of eDP1
.

Best regards,
Martin
