Issue with resume from suspend on asus vivobook x330ua

[rkunschke]

Describe the bug

When I have my laptop on battery and it goes to standby everything works like expected. But when it's on the power cord and goes to standby it doesn't. It reboots instead of going to standby and I am at the sddm login screen.
I've tested the bazzite-default and the bazzite-asus image.

With the default-image I get the well known blinking-shift kernel panic when entering/resuming from standby. That what i saw on arch, open suse and many other distros as well. With the asus image there is no kernel-panic but that weird reboot on power cord issue. That is something I never saw before.

What did you expect to happen?

The laptop should suspend and resume instead of rebooting.

Hardware

(Asus) VivoBook S13 X330UA

Extra information or context

I was really surprised no one else seems to have these kind of issues. I had them on every laptop/distro I've ever owned.
Which logs should I provide to figure out the issue?

What I noticed as well: When I log in after that forced reboot the screen goes black and I have to move the mouse so it turns on again. The screen brightness it lowered so it looks like the laptop thought it was out of battery. Maybe something with fedoras tuned deamon?

can you give me the output of cat /proc/acpi/wakeup

[rkunschke]

sure that's it:

Device  S-state   Status   Sysfs node
RP01      S4    *disabled
PXSX      S4    *disabled
RP06      S4    *enabled   pci:0000:00:1c.0

HDAS      S4    *disabled  pci:0000:00:1f.3

hmmm try each of these and see if it resolves the issue, if so you'd want to make them into part of a boot script

echo XHC | sudo tee /proc/acpi/wakeup

echo RP06 | sudo tee /proc/acpi/wakeup

They both didn't solve the issue. The second one makes my screen go black when switching between plugged and unplugged. The first changed nothing.
Edit:
Now the bug happened to me also while being on battery. It's always a bit random when it happens and it happens not every time.
I think it has to do with going to standby while the lit is closed. Manually activating the standby mode never resulted in that bug. I will test now if it happens when I go to standby an then close the lit.

[rkunschke]

I've tracked down the issue a bit the last few days.
The issue is related to to running on battery/power. When running on power cord it happens every time and on battery only sometimes.
The issue only happens when the screen is turned off due to closing the lit or because of idle.
When the laptop suspends while the screen is on it never reboots but when the screen is off it reboots every time instead of going to suspend.
I've disabled the option to turn of the screen while closing the lid or on being idle and the laptop suspends normally.

So weirdly the laptop is only able to suspend while the screen is turned on.

I've tried out different solutions and found out something interesting.
When I set the kernel parmeter i915.enable_dc=0 via rpm-ostree kargs --editor everything works like it should. The setting seems to control a power saving feature of the display controller. https://wiki.archlinux.org/title/Talk:Intel_graphics#Incorrect_statements_regarding_power_usage_penalty_of_enable_dc=0

Should we provide a device-specific workaround for that in any form?

@rkunschke drafted a ujust recipe to make this easier, would you mind testing it? you can save this file to your desktop, then in terminal

cd ~/Desktop

then

just --justfile 81-bazzite-fixes.just toggle-i915-sleep-fix

#2145

Okay thank you :) I will do the testing tomorrow/
