[Solved] System Freezes after resuming from Hibernation

phoenix324 · 2024-06-11 00:28:28

I saw https://wiki.archlinux.org/title/Power_ … nsistently but in my case the behaviour dosen't matches any of them.

OS: Arch Linux x86_64
Host: GL65 Leopard 9SDK (REV:1.0)
Kernel: Linux 6.9.2-zen1-1-zen
Shell: bash 5.2.26
WM: Hyprland (Wayland)
CPU: Intel(R) Core(TM) i7-9750H (12) @ 4.50 GHz
GPU: Intel UHD Graphics 630 @ 1.15 GHz [Integrated]
Memory: 3.50 GiB / 15.42 GiB (23%)
Swap: 0 B / 24.00 GiB (0%)
Disk (/): 267.98 GiB / 451.44 GiB (59%) - btrfs

So the behaviour i am facing is like this, i hibernate my systemd ( automatically or using manually ), when i resume after several hours. I see my lockscreen ( hyprlock ), my keys are not regestering, i can't change tty. So i do SysReq+R, this gives me back control of the keyboad. Now i can switch to different tty's. The Screen froze on tty1. So when i switch to other tty's. I am not able to come back to tty1. For example i am in tty3, If i do Ctrl+Alt+F1, the screen of the tty3 will still be showing but no keystrokes that i press will update the screen, then i switch to tty3 and input gets registered in tty3.

From the https://wiki.archlinux.org/title/Power_ … nsistently,

A problem may arise when using the hardware watchdog timer...

i have disabled watchdog timer ->

[phoenix@ArchLinux ~]$ cat /proc/cmdline 
initrd=\intel-ucode.img initrd=\initramfs-linux-zen.img root=UUID=ff5d4ba3-25ce-46cd-9bab-dc98091801b1 rw rootflags=subvol=@ quiet splash loglevel=3 mitigations=off nowatchdog modprobe.blacklist=iTCO_wdt fbcon=nodefer vt.global_cursor_default=0
[phoenix@ArchLinux ~]$ cat /proc/sys/kernel/watchdog
0
[phoenix@ArchLinux ~]$ wdctl
wdctl: No default device is available.: No such file or directory

Sometimes the screen goes black due to device initialization from within the initramfs

I do have kms in hook, but my screen dosen't go black. So not sure if this is what affecting me.

HOOKS=(systemd autodetect microcode modconf kms keyboard keymap consolefont block filesystems)

For NVIDIA users, blacklisting the module nvidiafb might help.

i have integrated + dedicated (nvidia) but i have disabled nvidia using `udev rule` https://wiki.archlinux.org/title/Hybrid … screte_GPU

Laptops with an Intel CPU that load the intel_lpss_pci module for a touchpad may face kernel panic on resume (blinking caps lock)

i can still access other tty's after doing SysRq+R and loginto those tty and run any command or DE.

My journalctl since i hybernated, hibernation starts at `Jun 10 22:07:40`, `journalctl --since '2024-06-10 21:54:00` http://0x0.st/XbCH.txt

P.S - is it Hyprland fault?

Disable zswap.

Does https://wiki.archlinux.org/title/Intel_ … Intel_CPUs help ?
https://bbs.archlinux.org/viewtopic.php … 2#p2175242

What happens if you kill hyprland/isolate the multi-user.target?
Is this strictly limited to hibernation or is suspend to RAM (S3 or S2idle) also affected?
What if you omit hyprlock?

Sorry, totally forgot about this. The problem is solved, it must be on Hyprland side as i didn't do anything explicit to fix this.
