I am getting a lot of Xorg crashes and hangs lately, which force me to restart the computer. I checked /var/log/Xorg.0.log and /var/log/Xorg.0.log.old but there are no errors.
Maybe you should upload the log files or at least the errors shown in the log so we can understand what's the problem
Here are the logs:

Xorg.0.log.old: http://paste.ubuntu.com/p/CmBp757xtY/
