I installed CloudCompare on my ubuntu machine using snap but I cannot launch the application. I get the following error message:
QXcbConnection: Could not connect to display :0 Aborted (core dumped)
If I enter $sudo cloudcompare.CloudCompare instead of just cloudcompare.CloudCompare, I get the same with one more line that is :
mkdir: cannot create directory '/run/user/0': Permission denied
Even when changing acces control and permissions this won't go away.
I have the following GPU: NVIDIA GF106GL (Quadro 2000)
And I am on ubuntu 16.04 LTS
I tried changing the access privileges, removing and re-installing both snapd and cloudcompare, updating my GPU drivers but nothing works.
If anyone has an idea, I would be relieved to hear it :)
Somehow installing Meshlab with snap fixed the issue for me : after the installing process was completed, I tried launching CloudCompare again and it works !
Hopefully, this will be useful to someone else :)
