Describe the bug
Xiaomi Redmi Book 14 2022
Ubuntu 22.04 after update boots only in recovery mode or with kernel option nomodeset
ACPI patch stopped working, so can not adjust monitor brightness. ACPI Patch Reinstallation did not help. linux-firmware update to 2023-08-04 did not help, linux-kernel-6.1.46\6.2.11\5.15-79
for ubuntu 23.04
list all firmware version
sudo apt-cache showpkg linux-firmware - lists all available versions.
sudo apt-cache policy linux-firmware - shows just the installed and available versions.
sudo apt list -a linux-firmware - to find out what versions are available.
install old firmware
sudo apt-get install linux-firmware=20230323.gitbcdcfbcf-0ubuntu1.2
or
sudo apt-get -t=20230323.gitbcdcfbcf-0ubuntu1.2 install install linux-firmware
"holds" the package at the current version, preventing automatic upgrades.
sudo apt-mark hold linux-firmware
update linux-firmware in all initramfs
sudo update-initramfs -u -k all
linux-firmware=20230323.gitbcdcfbcf-0ubuntu1.2 breaks amd64-microcode pkg, but installation with --auto-deconfigure did not help
20230323.gitbcdcfbcf-0ubuntu1.2 - this pkg for ubuntu 23.04
for ubuntu 20.04 execute sudo apt-cache this will show all packages linux-firmware
maybe that 's the problem ?
i use ubuntu 23.04 without any patch (kernel 6.2.x)
