Ubuntu 21.10 boots to black screen

Yestarday I upgraded from Ubuntu 21.04 to Ubuntu 21.10 but when I rebooted my laptop (Asus X505BA) and tried to login with Xorg I got a blackscreen. After that, I restarted my laptop again and I tried to login with Wayland but I got a blackscreen too.

I thought this could be caused by an upgrade error so I reinstalled Ubuntu 21.10 but the problem persists. However, I can "avoid" this problem if I login to text mode and then run startx. Unfortunately if I do this, the system starts in low resolution and some applications don't work.

Is this a bug?

According to many bug reports it's a kernel bug in kernel version 5.13. Upgrading to kernel version 5.14 or downgrading to kernel version 5.12 solves the problem.
