Ubuntu version issues affecting brightness settings
Last night I reduced the screen brightness on my HP EliteBook 2540P using Ubuntu 18.10, as shown here. The issue is that I can't raise it beyond a low setting, and no articles have solved the problem. I don’t have another USB drive and worry about losing important data. Here’s a photo of the brightness level I reached: If you can offer any assistance in the comments, it would be greatly appreciated. It’s frustrating having to squint to see the screen. Thanks ahead! EDIT: I verified for the latest updates and everything looks up to date according to Ubuntu!
I've already tested this method, but it didn't resolve the issue. I also used xbacklight without success. With automatic brightness enabled, I disabled it and it worked again.
It seems the backlight hardware could be faulty, though reinstalling might resolve the issue. Start by booting from the live setup to check if the backlight functions correctly; if not, attempt a reinstall. Otherwise, it likely indicates a broader problem with your laptop.
