Created attachment 121304 [details] Xorg log file I have had multiple random xorg crashes occur at different times but almost always when I am away from my computer and the lock screen is started. Sometimes it is a few minutes after I have left my computer, sometimes multiple hours. I have attached my dmesg and Xorg.0.log file. I am using Kubuntu 15.10, with a vanilla 4.2.8 kernel.

fd_mitch@ptaff.ca, thank you for reporting this and helping make Ubuntu better. However, you are using a downstream version of the xorg stack, and kernel. Please follow these instructions to have apport report a new bug about your crash that can be dealt with by the automatic retracer. First, execute at a terminal: cd /var/crash && sudo rm * ; sudo apt-get update && sudo apt-get -y dist-upgrade && sudo service apport start force_start=1 If you are running the Ubuntu Stable Release you might need to enable apport in /etc/default/apport and restart. Now reproduce the crash, then open a terminal, navigate to your /var/crash directory and file your report with: sudo ubuntu-bug /var/crash/_my_crash_report.crash where _my_crash_report.crash is the crash you would like to report. By default, this sends the crash to the Ubuntu Error Tracker infrastructure, which is different than Launchpad. For more on this, please see https://wiki.ubuntu.com/ErrorTracker . However, if after doing this you would still like to have a crash report posted to Launchpad, for example to ease triage and add others to your report, one would need to open the following file via a terminal: sudo nano /etc/apport/crashdb.conf and comment out the line: 'problem_types': ['Bug', 'Package'], by changing it to: # 'problem_types': ['Bug', 'Package'], Save, close, and file the crash report via: sudo ubuntu-bug /var/crash/FILENAME.crash Where FILENAME is the actual name of the file found in the folder. However, this report is being closed since the process outlined above will deal with this issue more efficiently. Also, please do not attach your crash report manually to this report and reopen it. Thank you for your understanding. Helpful bug reporting tips: https://wiki.ubuntu.com/ReportingBugs
