[Maksim Beliaev]

After sleep the monitor which is connected to HDMI does not wake up. Unplug->Plug helps, but not sustainable

Please try running the external monitor at a lower resolution like 1920x1080. If that prevents the bug then it means you might need a higher quality HDMI cable.

[Maksim Beliaev (beliaev-maksim)]

I do not think it could be related to HDMI cable. How then switching to TTY and to desktop resolves the issue?
why is the screen awake after the boot ?

[Daniel van Vugt (vanvugt)]

HDMI connection and bandwidth detection problems are intermittent. A higher quality cable (or lower bandwidth requirements like lower resolution or refresh rate) makes them less likely/frequent.

[Daniel van Vugt (vanvugt)]

Please test a lower resolution. If that works then we can group this with bug 2066129.
