#WINDOWS BRIGHTNESS NOT CHANGING PATCH#
Pretty sure I need to somehow patch the i915 driver. I have also tried those parameters before and they did nothing. My kernel parameters did not contain either 'acpi_osi=linux, acpi_backlight=vendor' when I added 'i915.enable_dpcd_backlight=1'. Removing the lines and doing a cold reboot restored backlight function. Click on device installation settings (i had to translate the buttons name from dutch to english), click on no and restart the laptop. Maybe doesn't apply to your Legion unit, but have you tried removing these kernel parameters 'acpi_osi=linux, acpi_backlight=vendor' ? I added these on a test Thinkpad T14s (AMD) uni and the backlight stayed constant and couldn't be changed by the buttons FN+F5/F6. I had to search in for sysdm.cpl (remove quotes before use) and go to the hardware tab. I have seen the bug report regarding the sound before.
I probably have to patch the kernel, but I'm not too familiar with doing that. Just adding the kernel parameter didn't work. Like you mentioned Legion 5Pi is a different device and the brightness issue is still present:

After some time you will also get updated drivers from upstream and then you will also not be required to add this kernel parameter. You only need to add `i915.enable_dpcd_backlight=1` as kernel parameter and your backlight issue will be resolved. Legion 7i backlight issue is already resolved: Ī friend of mine has this laptop so I have already confirmed this with him and it is working. I only get sound with external speakers or bluetooth. Off topic, but do you guys have working internal speakers? Mine doesn't work. Just adding that I have a different laptop with similar specs.
