I just received my 12th gen intel laptop and installed Ubuntu 22. It seems that the brightness keys aren’t working out of the box. The media and volume keys work, and I’m able to change the brightness from the system menu. Does anyone have an idea of how to fix this?
I’m totally new to linux and I’m having the same problem - can someone walk me through how to actually do these steps for the fix? I assume I have to put something in the command terminal but I really don’t know what specifically to type or look for, so I’d really appreciate some help
Nevertheless, I have a (un)related problem. For some reason I can’t change my brightness with above or below a 8% since a few days. I have no idea what triggered that. If I use the keys or even the adjustment with the mouse, it directly jumps back to 8% after I let go the slider. Anybody has an idea what could be the reason for that odd behavior?
No it did not happen after an update. I think it happened after I started using an external screen via HDMI a few weeks ago. Otherwise I did not do/change anything. I tried to find a solution but all the threads I found where related to backlight not workin in ubuntu.
@LEEH Since it’s working at some level, let’s set aside the brightness keys and take this approach instead.
Scroll down for the Ubuntu package install, then follow the directions to try different brightness settings in the terminal.
@Paul_Walker Didn’t catch the distro you were using. Regardless, if this is a 12th gen Framework, please try removing the modprobe blacklisting, then add it directly to grub instead. If Ubuntu or related, follow the Ubuntu guide.
Thank for the suggestion! The “light” package and adjusting the brightness in the terminal works. It is odd that it doesn’t work with the keyboard keys or in the GUI settings. Nevertheless, it works in the terminal, good enough for me.
I am a student who is new to linux. I successfully installed ubuntu 22.04 on windows 11 a few days ago. I want to adjust the brightness of the screen, but the “Display” in the “Settings” does not have a brightness slider. I checked the information on the Internet but it didn’t work.
Can anyone help me? Thanks
