I don't know how to call it anything else. I installed Mint about a week ago and began installing stuff, alright. While doing that, I figured I should upgrade the system through apt and did so, getting a kernel upgrade and whatever in doing so.
After a reboot, however, the screen got this phenomenon, basically some red to white colors began appearing cyan. At first, occasionally the colors flickered and even fixed itself for a bit but reverted into the broken state later. Even as I write this, this text box has a cyan background.
The problem seems to be hardware-related since the color fault is present both on both Mint as well as my Debian and Win7 installations. Any help with this?
