I am experiencing screen brightness issues on Lenovo Yoga Slim 7 14ITL05 with Fedora 36 operating system:
- at the installation phase, I configured the system encryption → there, after each character I type for the password prompt to decrypt the disk, the screen gets completely dark for a second
- at normal operation of the laptop, when browsing Internet pages with Firefox, I can sense that the brightness changes, especially on white-background pages
I have just migrated my laptop from Arch Linux, where last update made my screen completely dark and unusable.
Could you please suggest how to debug such an issue?
I thank you in advance.
