I plugged in a mouse and since then even though its unplugged now and system rebooted drop down menus toggle and sliders don't work it makes a noise like I'm changing it but theu don't move in steam deck image before it was working perfectly
Plugging the keyboard and mouse back in fixes the issue even after unplugging again but as soon as reboot it stops working unable to change any toggles in menus sliders or drop downs
if efibootmgr and uefi bootorder is not respected, then you can forcefully change it, not sure how the deck will handle this so you will be on your own if you do this on a deck, but you can rename the BOOTX64.EFI file (rename, dont delete, incase your machine for some reason dislikes this forceful change and you need to restore the original file) on the EFI partition and copy grubx64.efi into the same folder as BOOTX64.EFI and rename the grub efi to BOOTX64.EFI.
in theory that should force grub to be first until windows wipes the EFI partition to reinstall its own bootloader in a random update (and this is why we install windows and linux on separate disks)
