Thank you for taking the time to report this bug and helping to make
Ubuntu better. We are sorry that we do not always have the capacity to

Ubuntu 16.04 (xenial) reached end-of-standard-support on April 29, 2021.
I'm setting the status of this bug to 'Incomplete' as it's not seen any
activity for some time. If this is still an issue when using a currently
maintained release of Ubuntu then please let us know which one(s)
otherwise this bug report can be left to expire in approximately 60 days

Title:
Xorg freezes regularly on login, more likely immediately after boot
Status in xorg package in Ubuntu:
Incomplete
Bug description:
I regularly get Xorg freezes if I log in immediately after booting,
and only when when running dual 4k displays (internal and external).
If I alt-ctrl-F1 to virtual console, login and enter a catchall
$ sleep 20 && kill -9 -1 0
and then alt-ctrl-F7 to attempt an X login, the Xorg freezes seem to
happen less often. When the freezes do happen, the kill statement
returns the X login prompt. Typically (but not always) when repeating
this process a second time, the X login succeeds.
