Hey everyone. I seem to keep getting random segfaults and I'm pretty sure the graphics card is the culprit but I'm not sure how to troubleshoot any further. This has been happening for 2 to 3 years and doesn't seem exclusive to Ubuntu (I dual-boot windows and occasionally get blue screens). The faults only result in the application terminating and requiring a restart. I've seen it across Steam, Dota2, Chrome, and the window manager which all would seem to have graphics utilization. I'm just looking to have a bit more of a smoking gun before purchasing a new graphics card. Any help is appreciated! Here's a sample of kern.log outputs from different crashes:
