Title:
after upgrade to 5.4.0-66 monitor remains black after off/on cycle
Status in linux package in Ubuntu:
Confirmed
Bug description:
i updated today to linux kernel 5.4.0-66-generic.
since then the monitor (HDMI) remains black when switched off and on again.
this can be corrected once, if a virtual text console hasn't been used so far
by switching to a virtual text console and then back to the desktop.
