Hello I have a problem with ubuntu. Visual fatigue is the problem. After using my pc, my eyes feel really tired. The problem? I have an LED monitor so it's not the technology that's the problem, ubuntu is the problem. Xorg to be more specific. This actually only happens in linux. In windows 7 I don't have any problem with this. It is very strange and I don't know what to do. Please help I want to use ubuntu again... without my eyes burning D: The only thing that I know is this: https://veuwer.com/i/3kgn But this seems specialized. Is a 59 framerate normal? Is my monitor incompatible? Thanks for your help. My monitor is a samsung s19d300
59.79 is really 60. Sometimes refresh rates are off of 60 by a tiny bit, but it shouldn't matter. Any visual fatigue you're experiencing could be fixed by using a different desktop environment, such as GNOME, MATE, KDE, or LXDE. You could also try using a background with slightly dimmer colors.
However, I feel that eye fatigue is somewhat subjective. If you experience it while using your computer, I recommend maybe seeing an eye doctor or taking a break from the screen for a while. There really isn't a catchall fix (and I've honestly never heard of anyone complain of this before), but here are some more things you can try:
F.lux -- Puts a yellow tint over whatever the computer is displaying - good at night.
Lower your screen brightness -- Ubuntu might actually make your screen brighter than Windows or something weird like that.
Suggestion from hbdgaf: If you have a webcam, you can try this program, which adjusts your screen brightness automatically based on the amount of light your webcam sees. For people that have a problem focusing on two different lighting conditions, this problem would happen mostly at night/in dark surroundings. Darker colors do the same thing. Dull the differential between your screen and the background.
I said it before, but a different desktop environment really might help. GNOME and MATE both use darker colors than Unity.
Increase your font size. Maybe your computer's font is too small. Refer here for more info.
Hopefully one of those helps. Since it's really a problem with your eyes or configuration, we can't provide a definitive answer.
