Linux 4.15-rc1 Kernel Released

[Masush5]

More likely it is that gnome is not compatible with Mesa. Or buggy configuration in the distro kernel. Use a custom kernel, Oibaf ppa Mesa dev and Xfce. My Ryzen 5 1600 & RX560 PC works rock solid, now for second day. I have played several hours Tomb Raider 2013 and Portal 2. Disable standby features from the kernel, turn you computer off when you are not using to make components last longer. A custom no debug kernel with ssd and Xfce boots ultra fast and shuts down immediately.

Startup finished in 2.001s (kernel) + 907ms (userspace) = 2.909s

No, setting gamma/color-temp is broken. Here is the patch which should fix it, but it hasn't made it into 4.15-rc1:

Do SI cards benefit from amdgpu.dc=1 now or will be in the future ?

I have a SI 7870 in a myth/steam box and with initial usage I haven't noticed any adverse side effects with running 4.15-rc1 with amdgpu.dc=1.

A quick update on my end: Night Light in GNOME is currently not working and I experienced a freeze (had to reset computer) a few seconds after resuming from Standby.

Yeah, setting gamma/color-temperature is broken for me as well.

I have to say, I'm a bit disappointed this (https://bugs.freedesktop.org/show_bug.cgi?id=103489) regression I reported a month ago, which causes my machine to lock-up 100% of the time when my 4k TV is enabled, made it into -rc1.

RX480 here and 4.15-rc1 on Ubuntu 17.10 and Mesa 17.2.4 is running buttery smooth for me with the amdgpu.dc=1 setting. HDMI Audio working as well. I can't wait til FreeSync makes it in.

So I just tried the spin from Ubuntus mainline repository, and DP audio from my Fury to my MG279Q is still not working unless I resample everything to 48khz.

debianxfce I know the timers api was refactored in 4.15, that's likely the source of your problem. Here's the patch that did the refactoring (there may be others): https://patchwork.kernel.org/patch/10074919/

Just upgraded, performance in actual OpenGL applications seems to be fine, but I noticed I couldn't even move windows around smoothly. Apparently this broke vsync'd window management with compton (a compositor for WMs), especially the opengl-swc and opengl-mswc methods of vsync. The other methods of vsync took a huge performance hit and results in windows not being able to be moved smoothy, no problems on 4.14. I know early release candidates can be pretty buggy, I'll give it some more time and wait for rc2. Maybe some userspace packages need to be updated too.
