Hello everyone, I'm having an issue where I get a segmentation fault while my screen is locked using xscreensaver. Though it doesn't seem to happen right away. I'll lock my desktop, walk away to go to a meeting or something along those lines. When I come back, my X session has been killed, and I'm back at the CLI. Here's some info:

I removed nouveau and installed the proprietary nvidia driver. Seems to be working for now. No issues so far. Don't know what the underlying cause was, though.
