I recently built a new computer. First I installed Ubuntu 14.04, but I experienced repeated system lockups while playing tf2, as well as some other unrelated system stability issues, so I abandoned Ubuntu 14.04 for Kubuntu 14.04, since Kubuntu worked well for me (tf2 included) in the 12.04 release. Unfortunately I still experience the same system lockups with Kubuntu. I'm about 90% sure it's a steam / tf2 issue, and not an Ubuntu bug since I experience no instability outside of tf2, including when I play other graphics intensive games. Keep in mind these aren't game crashes or steam crashes, my entire system locks up and is unresponsive to any form of input, including the alt+sys+REISUB key combination, requiring a hard shutdown using either the reset or power button. When I restart there is no meaningful output in kern.log syslog dmesg or Xorg.0.log, I've starting steam from the console and redirecting stdout and stderr to a text file, which also contains no relevant output. I've run TF2 on the highest possible graphics settings and the lowest possible graphics settings and experience complete system lockups using both configurations.
