Got a newer nvidia driver (470) to work with this kernel over the
holidays.
The issue still applies, regardless of the GPU selected in prime-select.
I started getting new ACPI errors with it, which could be unrelated
(empty lines are in actual output):
[ 196.405777] ACPI Error: Thread 25047680
@koba
nvidia module won't even build against oem kernel 5.14, so I can't test
that. Removing i915.enable_psr=0 is not really a supported configuration
on this machine. Keeping PSR on causes it to occasionally hard freeze
after hours of work.
tbh after all this time I've lost any hope of this
let's just focus on stock linux for this

@Georgi, could try these
1. prime-select intel and reboot, check the issue.
2. prime-select nvidia and reboot, check the issue.
please remove "i915.enable_psr=0 i915.modeset=1 nvidia_drm.modeset=1" from
cmdline

If that would help, I could run the same scenario on a 9560 laptop to
maybe see what's different in the logs?
The 9560 does not have this problem, although it comes with a previous-
gen Intel GPU, HD630 vs UHD630 on the 9500.

@koba, the issue still present on that one. Logging seems borked in that
RC, it only started ~1s into boot.
In the attached log,
1. the affected monitor (BenQ) "went away" after logging in at boot
2. came back after getting power cycled
3. suspended and woke fine on first Super+L
4. went away
@Georgi, would you please try 5.15, please get the ARCH=amd generic files and a
header with "all" postfix file.

@koba, would it be better to move this issue to

likely related to Thunderbolt in this generation of XPS going to Titan
Ridge?

@koba, the latest drm-tip triggers it more reliably. When I lock the
screen, the issue triggers every single time after the external monitor
goes into standby, and it needs to be power-cycled to wake up.

A couple of other behaviours I have observed now that may be useful for
figuring this one out:
1. When this monitor (Benq EX2780Q) goes to standby, it stops showing
signs of life on the signal line. This manifests as it disappearing
completely from the system, including the sound output and the

Yes. Even if I disconnect everything but the monitor from TB16 and the
remaining USB-Cs on the laptop, keep the laptop lid open and use the built-in

lid open, the laptop screen wakes up, but the external

if you only plug the external monitor on tb16, would the issue be seen?

@koba,
5.12 logs attached.
It was triggered a few times during boot, but I checked dmesg before
locking the screen and triggering the issue - it was at timestamp
20:18:43, so the lines you are interested in will be shortly after that.

@Georgi,
would you please also collect dmesg(drm.debug=0x10e) after issue is
triggered?
Thanks a lot

@Koba,
Not sure what you meant by that, could you elaborate? Do you want me to
send the laptop into s2idle suspend?
That is not necessary to trigger the issue; merely locking the screen or
letting the monitor go blank after a timeout triggers it, although it
may take a couple of attempts
@Georgi,
Would you please dump a log for s2idle that triggers the issue with
5.10-oem-1025 kernel?
Please also enable drm.debug=0x10e

In this instance, it took several monitor power cycles and reopenings of
the lid for it to put output on the external monitor after logon, even
though it was clearly showing up in Display Settings.

Please help to collect another one.

The apport-collect run for this was actually perfect: the external
screen didn't wake for LUKS and didn't wake for the greeter afterwards,
so I had to get the laptop out of the stand and open the lid to be able
to finish booting. I hope the logs have captured all relevant
information.
