I have a Lenovo g470 with Windows 8 used for games only, and a Linux Distro used for development and as my main OS.
I used to have Elementary OS, it was working well, but I decided to try CrunchBang. I installed it and everything went fine with the installation, just some little problems about wifi that I solved easily. After some minutes setting OpenBox, conky and tint2 to my desires I had a big headache, and my eyes felt very sore. I could notice that the screen flickered a bit, like CTR with a low refresh rate. It's more noticeable on darker colors and on the corners of the screen.
I checked my refresh rate an resolution, and everything was fine, the resolution and refresh were set to the native ones (1366x768 60hz) I thought that it was a video card drivers related problem. My computer has two graphics cards, an integrated Intel HD3000 and a discrete Ati HD6370, I tried with both cards. Using the intel drivers, and for the ati, the privative and open source ones with no difference.
After looking for answers and trying some setting with xrandr, I gave up and tried with another distro. This time Arch Linux. I installed the base system, intel video drivers, the latest version of Xorg and OpenBox but I found the same problem. I don't have any idea of what's wrong with this. I'm already trying with Linux mint, and the problem is also present here, I'm sure that it's not a harware fault, because I can use it fine with Windows, Ubuntu and Elementary OS.
Any idea of what could be wrong? Or any different setting present on Ubuntu by default and that all other OS are missing that could be causing this?
Thanks in advance.
