Hi Koba,

I got these warnings during apt install linux-image-oem-20.04-edge:
W: Possible missing firmware /lib/firmware/i915/tgl_huc_7.5.0.bin for
module i915
W: Possible missing firmware /lib/firmware/i915/tgl_huc_7.5.0.bin for

dunlap@lt9:~/Desktop$ uname -a
Linux lt9 5.10.0-1008-oem #9-Ubuntu SMP Tue Dec 15 14:22:38 UTC 2020 x86_64
x86_64 x86_64 GNU/Linux
dunlap@lt9:~/Desktop$

With 5.10.0-1008-oem the external monitor does not turn on when first
booted.  It does turn on with 5.6.0-1036-oem but not in the configuration
I had previously chosen.

By fiddling with the "Display" GUI from the "Settings" menu I can finally
get it turned on but that state is not maintained on boot.

Also, the external display is off for perhaps 30 to 60 s after booting
during which time the dock seems to be off because I finally get a notice
that the Ethernet connection comes on.

The dock seems to be turned off and then on during some of my interactions
with the "Display" GUI.  All quite slowly.
I will go back to 5.6.0-1036-oem for now.

Thanks for your help.  Regards, John
