Editor wont start in Ubuntu-assertion failed

So i am trying to run UE4 on my linux machine. After folowing this unreal doc on how to make UE4 work on linux, i encounter this error when starting up the UE4Editor.

r: ‘Could not create GL context: GLXBadFBConfig’

I had exactly the same problem after doing a routine security update. I finally tried rebooting, and that did the trick for me. That was a couple three days ago, and it has been fine since.

Thank you for the answer. Unfortunately that did not help me…:frowning:

Come to think of it, I also compiled everything again. Maybe that did something after all.

I wish I had been taking notes as I experimented. At the time, I was just focused on getting UE4 running again, so I could get back to work.

Rrecompiled everything, still nothing.

The update I did replaced all the NVIDIA 346 stuff with NVIDIA 352 stuff. Researching the error suggests that it “is typically due to incompatible or obsolete video drivers being used by the X11 desktop.”

I have the following installed. Compare, and maybe there is a clue here:

ii  libcuda1-352                                                352.63-0ubuntu0.14.04.1                    amd64        NVIDIA CUDA runtime library

Excuse me. Wrong list. What I mean to show is that I have a bunch of 346 → 352 transitional packages that all have 352 version numbers. Maybe this is a clue somehow:
