Been a while since I have been over here. Here is the situation.
I am running up to date Fedora 22 x64 on a Lenovo x120e using Xfce. Install goes back to about when 22 shipped.
For some time now, the video would be dim, like at the powersaving setting, but if I ran on battery and did no input for ~5 min then moved the mouse, I would get full video.
This little trick has stopped working. Laptop display is dimmed. I should mention that the external monitor is running at max video brightness. On boot, if I <Alt-D>, the notebook video starts bright, but quickly dims.
If I boot into bios, the video is dim. There is no video brightness option.
I have gone into powermanagement settings and set everything for max brightness. No difference.
I have looked here for any messages like this and have tried looking for bug reports with nothing coming up. So any ideas? Recommendations?
Does your laptop have an ambient light sensor? I had one go bad on an Acer laptop that would cause trouble. In my case it was flaky and would randomly dim/brighten. It has been a while now, but I think I had to short it out to get things working well.

No ambient light sensor that I have ever discovered. I have a few of these in service and have taken them all apart at times, though not the monitor piece. But I have had to read the maint docs and they do not mention one.
Recently, I have had to have blackout tape over my camera to enter a facility where I have contract work. Since they got me a contracter ID, I no longer need to do that, but have not taken the tape off, as I do not use the camera...
I took that tape off and no change.
Need to find a program in Xfce that uses the camera to test it out again..,

I have multiple desktops installed so I have "cheese" installed as well. It is a gnome app and may bring in more dependencies than you wish...but may be worth a look.

I tried using dnfex to search for camera programs and it came up empty. It also did not find anything for video, so I think there is something wrong with my setup. Cheese is not available within Xfce, so I dread what it would install. I DO have k3b, so some kde program would not add too much.

I don't have a camera on this box, but I do use Xfce, so I tried installing it and dnf wants to install cheese, cheese-libs and gnome-video-effects, for a total of 1.3M downloaded and 2.9M installed. Naturally, I said No.

Well, you could install vlc from rpmfusion. It supports webcams.

I forgot about VLC supporting webcams, as it is part of my 'base install'. Started it up and figured out how to get the cam on. Cam works, but notebook screen dim and external working fine.
:(
Well off to the airport soon, may not be able to do much for a couple days. Welcome any advise!

Well, you say you're running an up-to-date F22. And, I think, you've said it used to work OK but has been giving you trouble at some point after the initial install.
If that is the case, then booting to a LiveCD of the original F22 should not fail. I would try that first as well as trying a LiveCD of F23 which is the current version.

Oh, one more thing.....
I just noticed that on a laptop that I have if I set the brightness to MAX in the system-settings (I'm using KDE) but I use the FN key of the laptop and use the brightness UP/DOWN keys on the laptop I can control the brightness of the screen even though the settings remain at MAX.
So, maybe you have a laptop HW Function that you can play with?
DAH moment....

I am sitting in the Delta lounge until boarding time (just flying down to my parents in VA Beach for a quick visit), and was working on this super dim notebook screen....
I looked at the hardware maint manual and there IS an ambient sensor integrated with the camera clip. In fact I can see it right next to the camera. I will open up my 'hanger queen' system when I get back and pull the clip from that one to switch into this.
Meanwhile, boy, one really tends to forget about function keys beyond turning wifi off and on. Your recommendation to use the brightness control worked like a charm.
Thanks. I am good for now. Probably won't be until next week that I can swap out the ambient sensor Will post back then.
