I mentioned this on Micheal's review thread, but this is probably a better place to come for support.
I'm running my RX Vega on the open-source stack, following the instructions here: http://www.phoronix.com/scan.php?pag...ga-setup&num=1
Performance is great, but the gamma is way off; far too low, both in X and in the console/Plymouth. Ubuntu's purple Plymouth background is practically black.
Setting the gamma to 2.2 using xrandr makes things look better; However, setting it in the Monitor section in xorg.conf seems to have no effect, even though I can see from the Xorg log that the gamma adjustment is requested.
Also, I'm not sure explicitly setting a gamma of 2.2 is the right thing to do; Xorg log shows that the default value is 1.0; and I'd assume this maps to 2.2 as opposed to there being an expectation that it will be set explicitly.
I have previously run an RX480 on the open-source stack and had no such issues; Windows with the Vega card also looks correct, so I don't think I can blame the monitor or card itself.
