Package: x2goserver Version: 4.0.1.19 When I connect to a x2go server that has an nVidia GPU using nVidia's binary drivers most software (such as Firefox, Thunderbird, Cheese, Transmission GUI etc.) will segfault on launch. This can seemingly be fixed by setting the LD_LIBRARY_PATH variable to wherever the nVidia drivers are (i.e. for nVidia-361 drivers just run LD_LIBRARY_PATH=/usr/lib/nvidia-361" in the server's terminal. Alternatively it seems that you can switch to the Noveau driver and the issue won't occur, but this might not always be an option. There's also a thread on ubuntuforums (https://ubuntuforums.org/showthread.php?t=2337814) that also has a video of this bug in action. I'm using Ubuntu 16.04 with MATE.
