Hi all,

Could you maybe provide support with this issue.

Thanks

Ubuntu Version:
25.10

Desktop Environment (if applicable):
GNOME

Problem Description:
After recovering from suspend fn functions (change volume…) are not working on f1-f12.
Before Keyboard was not working but adding
GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash i8042.reset i8042.nomux i8042.nopnp i8042.noloop”
to grub fixed this.

Relevant System Information:

Model: Lenovo Ideapad Slim 3 16ABR8

Asus ZenBook UX425 function keys and sound stop working after deep sleep

**Distribution (run `cat /etc/os-release`):** ``` NAME="Pop!_OS" VERSION="21.…10" ID=pop ID_LIKE="ubuntu debian" PRETTY_NAME="Pop!_OS 21.10" VERSION_ID="21.10" ``` ![image](https://user-images.githubusercontent.com/34136215/153936079-5a9f8e3e-44e9-49d9-89ba-25f5c6cc4bde.png) **Issue/Bug Description:** My function keys (brightness, volume, etc.) and Fn Lock (Fn+Esc) stop working after I wake my Asus ZenBook UX425 (Intel 11th generation) from deep sleep (with kernel option `mem_sleep_default=deep`), hybrid sleep or hibernation. The sound also stop working. I need a reboot to make them works again. This issue does not appear if I use shallow sleep (without `mem_sleep_default=deep` kernel option). `acpi_listen` reports event at key press before deep sleep, but nothing is printed in the terminal after deep sleep. **Steps to reproduce (if you know):** 1. Boot Pop!_OS : Fn keys and sound work properly 2. Deep sleep or hibernate computer 3. Wake computer 4. Fn keys and sound does not work **Expected behavior:** Deep sleep and/or hibernate should work since battery drain with shallow sleep is high (about 30% overnight) **Other Notes:** It may be a kernel problem. I've updated my Kernel to 5.15.23 and there is no improvement. Should I report a bug for linux kernel ? Same issue repported here for Ubuntu : https://askubuntu.com/questions/1326292/fn-keys-and-sound-not-working-after-resume-from-deep-suspend-ubuntu-20-04-2-lt And here for windows 10 : https://zentalk.asus.com/en/discussion/48290/zenbook-13-ux325-fn-keys-not-working-after-sleep-anyone
