I updated my IdeaPad-5-15ARE05 to 5.7.10 (https://kernel.ubuntu.com /%7Ekernel-ppa/mainline/?C=N;O=D) with NO LUCK! Brightness isn't working at all.
The brightness buttons change the value in this file: "/sys/class/backlight/ideapad/brightness" (from 1 to 21) but not effective. I noticed that when I hit the brightness button (either - or +) sometimes the icon of the microphone appears on the screen instead of the brightness icon (see attached) Finally, on this page > https://askubuntu.com/a/1251189/70172 one user suggests that updating the BIOS solved the issue for him (But I'm on Ubuntu, and Lenovo only provide Windows .exe updater > https://pcsupport.lenovo.com/us/en/products/laptops-and- netbooks/5-series/ideapad-5-15are05/downloads/DS544050) Any help would be much appreciated, as with max brightness makes it impossible to use the laptop in the evening. ** Attachment added: "mic pic when adjusting brightness.png" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1881462/+attachment/5395881/+files/mic%20pic%20when%20adjusting%20brightness.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1881462 Title: Brightness settings don't work on Lenovo Ideapad 5 15ARE05 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1881462/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
