@Imre, any comments here?

If S3 is not the default state on your machine then I'm not sure we're supporting it.

Could you also send a drm.debug=0x1e log that also contains the suspend/resume sequence messages?

Could you try if you also see the corruption when using the FB console (switching to it when you see the corruption and doing a suspend/resume from the console)?

@Kloeckner 
We tried this issue on Dell Inspiron Ten generation i7-1065G7 with Ubuntu 19.10.
Can't reproduce this display issue.

We also upgrade the kernel to 5.4.0-rc5, still don't reproduce this issue.

Would you like to add i915.enable_psr=0 in cmdline in grub file?
And try to see whether you can reproduce this issue or not?
Thanks.

Thanks for your help, all!

> If S3 is not the default state on your machine then I'm not sure we're supporting it.

It is not the default. However, S3 support appears perfect aside from this issue--the machine is completely usable after resume on an externally attached screen. Just the internal display does not come back.

> Could you also send a drm.debug=0x1e log that also contains the suspend/resume sequence messages?

The dmesg debug log I sent earlier contained a suspend/resume cycle:

> Would you like to add i915.enable_psr=0 in cmdline in grub file?

With PSR disabled, the Dell logo does not get corrupted. It just stays in place. However, the content of my desktop still does not reappear on the built-in panel.

> Could you try if you also see the corruption when using the FB console (switching to it when you see the corruption and doing a suspend/resume from the console)?

FB console shows the same symptoms: external display comes back fine, internal display stays on Dell logo (or its corrupted version, depending on PSR state).

@Kloeckner 

Would you like to record a video again after you disable PSR in command line?
i915.enable_psr=0

Thanks.

@Kloeckner 

We use debian bullseye/sid with kernel 5.2.0.
After echo mem > /sys/power/state. And then awaken the system by keyboard.
The built-in display can recovery successfully, but the system hang.

It is not the same issue that you meet.
We still can't reproduce your issue.

Thanks.

I recorded another video with PSR disabled, see here:

https://ssl.tiker.net/nextcloud/s/8ZBQCMAHB6Hkg3q

Unlike before, the logo does not get corrupted, it just stays there. The machine appears unresponsive, but it is entirely usable from an externally attached display.

Note that I'm now running drm-tip, commit 41eb27f39e60d822edc75e6aaeb416b72bc1dcf2, and I have the required firmware blobs installed. The behavior hasn't changed though.

Likely a BIOS issue, as it also occurs in Windows, as pointed out by @arek.burdach in https://gitlab.com/emrose/xps13-7390_debian/merge_requests/4#note_242414579.
