When I run:
sudo apt-get update && sudo apt-get install octave
it froze about 5 minutes into that. Now when I boot up it freezes almost instantly after I log in. It's happened 3 times in a row now.
Switching to a different workspace doesn't unfreeze it.
I think I may have to do this:
i915.modeset=1
but I don't know where to do that.
Also, I think I may need to paste a log file here but I'm not sure which one.
