Hi I saw lots of posts here regarding Ubuntu eye strain issue. But none could answer my question. I use Intel i5 processor, AMD radeon Graphics card.
When I use my Win 7, there is no issue with my eyes for long time, but as soon as I use Ubuntu for even less than 1.5 or 2 hours, it makes my eyes dull. It makes eye strain, causes dryness of eyes.
When I try the
xrand -r 120, it says that the refresh rate is not available for the size.
I use a sony vaio 15 inch led laptop
