Not so good on reboot. External monitor came on first boot after changing
/etc/default/grub but not for subsequent reboots. Attached are dmesg
results for several reboots.

Hi Koba, Very good so far. Rebooted with both external and internal
displays running although in wrong modes which I changed. Will see how it
reboots shortly. -- John

Hi Koba,
5.6.0-1036-oem is much more polite than any of the 5.10 candidates you have
provided. 5.6.0-1036-oem boots to the correct configuration and usually
recovers from suspend to the correct configuration. Even better, it
doesn't turn off the dock when suspending or recovering from suspend.
changed /etc/default/grub and attached.
Also attached /var/log/dmesg
The external display does not turn on at boot but by requesting different
"Display" GUI settings the dock is rebooted (Ethernet connection is stopped
and started) and then sometimes the external display is started but usually
A while back that was some work-around. I'll run it without. Anything
else?

It's pretty jerky. Then after a number of cycles of blinking screen on the
laptop and the dock seemingly being restarted (the Ethernet kept going off
and on) the external screen came to life and now the system seems to be
operating normally. I did fiddle with the "Display" GUI a bit before it
I suppose these .deb files are the ones you'd like me to try:
-rw-rw-r-- 1 dunlap dunlap 11476820 2020-12-27 18:19
linux-headers-5.10.0-051000drmtip20201228_5.10.0-051000drmtip20201228.202012280203_all.deb

Thanks. I got -4007-oem to run. At boot it presented correctly with a
login box on the external screen and the laptop screen available. However
when I logged in both screens went blank for a bit after which only the
laptop screen was alive but it wasn't the primary so just blank. Right
Got all five .deb files then used this command:
sudo apt install ./*.deb
But, when choosing the -4007-oem kernel it says the signature is wrong and
quits.
The -1008-oem kernel still doesn't start the external display and the dock
doesn't run right away. (Ethernet doesn't work).
Back to
Apply all 5 modules?

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
module i915
W: Possible missing firmware
Although they all act a bit differently when restarting after suspend, none
of these kernels solve the problem:
Ubuntu, with Linux 5.6.0-1032-oem
Ubuntu, with Linux 5.6.0-1031-oem
Ubuntu, with Linux 5.4.0-52-generic
Ubuntu, with Linux 5.4.0-51-generic
The BIOS has been updated using:
When the two displays are mirrored the 5.4.0-51-generic kernel has come out
of suspend mode correctly about 10 times without any failures. I had
trouble earlier with that kernel when the displays were not mirrored. --

The above kernel works better than the oem kernel. 5.4.0-51-generic
usually (but not always) responds correctly from a suspend when I press
The oem kernel failed to display both the laptop screen and the external
monitor after a suspend. However the mouse did move the pointer around the
laptop screen. The only solution seemed to be to power cycle. -- John

So far so good with the oem kernel. I should have included in symptoms
that the problem is intermittent. -- John

Hi Koba, I don't know how to do that. I did make a recovery thumb drive.
