I’m not certain if this is a hardware problem or an Ubuntu problem but I’m asking here in case it’s an issue someone else has dealt with:
I have a Dell Latitude E6420 laptop running Ubuntu 18.04.1 and it will often freeze when running graphical applications. Dungeon Crawl Stone Soup and sometimes DosBox are examples of programs that are sometimes running when things just lock up and a hard reboot is the only thing I can do. The only clue at all is that the mouse can still move sometimes but it can’t interact with anything.
For all you experts, where do I start to begin solving this problem? What do I look for in the logs? How do I rule out a hardware issue? If this is too vague please delete the post and I’m sorry, but I don’t know where to ask this one.
Okay so the last error message after hard rebooting is this every time it happens:
nouveau 0000:01:00.0: INTR 00800000
Edit: Anybody? Even the smallest clue would be nice. I am pretty tech savvy and can do some digging if I could figure out where to start looking.
