Gnuplot crashed unexpectedly - ubuntu 18.04LTS
I've been having an issue with gnuplot (Version 5.2 patchlevel 2) on ubuntu 18.04.
When trying to zoom using the right click button, the window goes away.
I removed and reinstalled it but this didn't fix the issue.
My journal entries when it crashes are the following
Aug 17 12:20:23 xxx kernel: gnuplot[33387]: segfault at 0 ip 0000000000000000 sp 00007ffc90bb04f8 error 14

I'm not great at interpreting segfault errors so any help on that is more than welcome!
Also when plotting, before the canvas pops up I get the following on the terminal:

Solution 1:
I would recommend to reinstall GNUPlot and libraries from official repositories by
sudo apt-get install --reinstall gnuplot libwxgtk3.0-0v5 libpango-1.0-0
and check its functionality.
To fix the possible problem with video drivers install vainfo by sudo apt-get install vainfo and then check its output. To get video acceleration for Nvidia install the following package which provides nvidia_drv_video.so library by:
sudo apt-get install vdpau-va-driver
reboot and retry to launch GNU Plot.
