Symptoms
2 out of 4 monitors don't light up after suspend. This is a similar problem as this post but not quite the same.
Hardware
- Dell XPS 9320 plus (i7-1280P)
- UD22 Dock
- 4 monitors
OS
- LinuxMint 21.2 with kernel 5.19.0-50 (all is well except, 10-15% chance, 1 of the monitors doesn't revive after suspend and I just need to reboot)
- LinuxMint 21.2 with kernel 6.2.0-26 (where the problem occurs)
Software
- DisplayLink driver 5.6.1, 5.7.0, 5.8.0 Standalone Installer
Other info
Unlike this post, the service is always "loaded" and "active (running)" even when 2 monitors don't revive.

What I tried:
- Upgrade the DisplayLink driver to 5.7.0 then 5.8.0
- Upgrade evdi to 1.13.1 then 1.14.1
- Restart the service
Nothing worked. So far the most effective way is to logout/login, which is much faster than reboot. Somehow the DisplayLink driver causes a long hanging (120 secs) during startup/reboot.
