For a number of years I have happily used Ubuntu. However, I am having all sorts of problems now since I upgraded my video card and monitor. My monitor is a Benq 4k monitor, but I decided to upgrade my video card to a AMD R9 270.
I have installed the latest drivers from AMD, fglrx. This is when my problems started as follows:
- I can no longer play flash in firefox, the Adobe Flash plugin keeps crashing.
- Playing Youtube videos at full screen is like watching a slideshow, really slow, it seems like there is no hardware acceleration. Flash or HTML5 both are slow.
- I tried switching to Chrome as a workaround for the flash issue, which worked fine at the start, but now Chrome is unusable as all it does its keep flickering on my desktop when I start it up.
Is this all fixable? Or is a combination of 4k, AMD etc unusable on Ubuntu?
