Hi, i can’t seem to change brightness om my MSI Laptop, the slider is there and i can interact with it but it just aint doing anything, same with the f9 and f10 keys, they change the slider but my screen isnt getting any darker or lighter.
If it has any relevance, nightlight works as intended, just not brightness.
Here is my system info:

hi, welcome.
25.10 is a non-LTS version of kubunutu and may not have a complete set of the libraries and features of a full LTS release.
you can likely install from discover a GUI package called gddccontrol which can give you a brightness control and there is also a command line interface.
the next LTS release is going to be next month, so it might be less effort to just wait and see… then deal with fixing it then, if it’s still a problem.
Hi, thanks for the response!
I will likely just wait for when the next LTS release will be out, is it an automatic system update or do i have to upgrade my system manually due to it being a major release? (im relatively new to linux as a whole so i apologies if its a dumb question)
I tried the gddcontrol GUI package and got this, not sure if there’s something i can do about it since my monitor is the built in laptop screen.
you should get a system upgrade notice (orange button) in the system tray when the LTS package becomes available… just follow the instructions.
if the GUI tool does not recognize your screen then it will not be able to control it.
you can try the options given by the developer, or there may be some forums specific to your hardware running linux that you can search.
