ThinkPad E14 Gen 2 (AMD Ryzen 7 4700U) issues

I have arch running almost flawlessly on this laptop. However, whenever I close the lid or use any of the keyboard hot keys (brightness, volume, etc.) nothing works. IF I manually put it to sleep in KDE, then wake it up, everything works fine. I made sure I added amdgpu to the modules in /etc/mkinitcpio.conf and any of the acpi_backlight options in /etc/grub/grub.cfg do nothing.

Any ideas?

Re: ThinkPad E14 Gen 2 (AMD Ryzen 7 4700U) issues

I have a Acer Swift 3 4700U laptop running almost flawlessly, but I also have problems on sleeping (gpu crash after waking up). I just propose that many suspend-related problems are caused by the new "modern standby" by Microsoft, while I an not very confident, as I also replied in
https://bbs.archlinux.org/viewtopic.php?id=256365

Can you try

cat /sys/power/mem_sleep

and check it is

s2idle [deep]

OR

[s2idle]

Also, you say that you suspend your laptop from KDE and your laptop wakes up correctly. Is it the s0ix sleep or the s3 sleep? s0ix state wakes up in ~1 second while s3 wakes in ~3s. Besides, you can touch your laptop after hours and check is it a bit warm, or simply use a power meter, since s0ix sleep consumes the same power as merely turning the monitor, on both Linux and Windows for my laptop.

Re: ThinkPad E14 Gen 2 (AMD Ryzen 7 4700U) issues

Hi, I've got the same laptop (thinkpad e14 gen2 ryzen 4700u), I have the same issue with keyboard that it works properly only after suspending and waking the laptop up.
However closing the lid does shut down the monitor and it seems that the laptop actually goes to sleep by doing so, but I have yet to check that.
If you come up with a solution, could you please share it here?
Thanks

Do you have xorg-xinit installed? I had exactly the same problem with ryzen laptops (arch+KDE) that I own. Removing xorg-xinit fixes the issue.

I do log in via xinit (I prefer logging in via tty), so yeah I do have it installed.
I'll try lightdm then.

Edit: removing xorg-xinit and logging in via display manager doesn't solve the issue

Did you manage to get the keyboard working properly?
Also, does your fingerprint reader work? I couldn't get mine to work with fprintd...
