At completely random times my screen starts flickering between dark and bright, the meter comes up in the top hand corner as if i'm changing it myself but i'm not. Any ideas?
Definitely a laptop problem, hopefully not a hardware problem.
When I try to adjust my laptops screen brightness, it goes to some very low brightness and then the screen starts flickering (ie changing between different brightness levels). When my laptop boots, it's at full brightness, and when I adjust that, flickering starts. After that I cannot get it back to any non-very-low brightness.
My brightness is stuck at 100% when I have the power cord plugged in, and using the hot keys to change the brightness, or changing the brightness through the system brightness app does nothing until I take the level to 0 where the screen will go black.
I started having an issue with my S4 's screen flickering bright and low whenever the battery saver mode is engaged or when screen is dimming for any reason. Anyone have any ideas on what could cause this. I checked for other apps, now I either have to have the auto brightness off or manual switch it when going indoors or when any reason to dim screen. Frustrating.
Hello, forum users!
I have a laptop Samsung 300v5a-s19 with NVIDIA GeForce GT 520MX.
I have just installed Ubuntu 12.04.1 and then Bumblebee 3.0.1.
Now it works well without any lags, but there is one problem: when I try to change the screen brightness (by Fn buttons or in the System Settings (Brightness and lock)), display starts flickering.
I've bought an Asus Eeeee netbook because I heard they are good with Linux. I'm very much a new Linux arrival after a long time with Windows.
I've installed Ubuntu on the machine.
If it boots 'normally' the screen emulates a dark tunnel. If I boot from 'recovery mode', then choose 'resume normal mode' (followed by 'exit recovery mode'), the screen is brightness itself.
I have a crazy pixel in the bottom right corner of my screen. What is phenomenon? When the screen content is changing that pixel starts to flash random colours, but it show the right colour with static images.
Sorry for the crap qualty. If you pay extra attention to to the bottom right corner (on the video it is the upper right corner) of my screen you will see it.
