I'm a pretty big fan of Linux, so I've been trying to make a full switch. Recently, though, I've hit a bit of a snag with running some of my games. I play most of my games through Steam, and most of them work fine. However, all games that were made in Valve's Source Engine (Portal 2, Team Fortress 2, GMod) will run for about 5-10 minutes before crashing to desktop. Launching the games from the console reveals they end with a nice old segmentation fault.
I run UbuntuMATE 16.04 x64 edition. Here are my computer's "specs" if you wish to have them:
Lenovo Yoga Laptop
256GB SSD (Where Ubuntu is)
1TB HDD (Where the games are)
2.5 GHz Intel Processor
Intel Video Card
I've tried reinstalling mesa and installing the 32-bit packages for mesa and OpenGL. Is there anything I can do to fix this issue?
