Touchbar is displaying the buttons but it is not correctly functional

[Ahmed97i]

I've recently upgraded to big sur. After some unsuccessful boot attempts into Arch Linux (it crashed during boot several times) it booted and keyboard was functional a entered my login credentials and started gnome desktop environment by typing systemctl start gdm  It started and my touchpad was also functional but unfortunately my touchbar was not functioning correctly although it was functional before upgrading to big sur... @aunali1 what do you advising me to do? And please help me should I remove Arch Linux and install it virtually on macOS or should I deal with these inconsistencies that arch Linux on Mac has? Thank you @aunali1 in advance...

If the touchbar doesn't change mode (i.e. fn keys to special keys), try resetting the smc, which should make it go back to normal, but it will probably get stuck after a reboot.
