Recently, I had the opportunity to test both antiX 17.1 & MXLinux 17.1 AMD64 images on some unique & new hardware. I happened get my hands on a laptop with a Ryzen 7 2700U with Vega 10 embedded graphics (i.e., https://en.wikichip.org/wiki/amd/ryzen_7/2700u). Unfortunately, the X.org server could not start due to a lack of kernel support for my graphics.
The latest Refracta ISOs behaved better on my hardware and X11 started (i.e., a Devuan derivative). I installed and tested Refracta, updated the kernel to 4.15 backport and then compiled and installed Mesa3D 18.0.2. Liquorix latest kernel would not boot at all regardless of which boot parameters are set. After a few hours’ configuration, I had everything working as expected except backlight brightness & suspend/resume. It seems my display driver wasn’t detecting the monitor properly after resume. I suspect both issues were interrelated. lspci noticeably reported a lack of any Ryzen graphics even with linux 4.15. PCLinuxOS shared the same issues with Devuan. I soon became convinced newer hardware support was necessary.
PCLinuxOS latest, Devuan Ascii, and Fedora 28 will all boot properly on my hardware. XUbuntu 18.04, antiX 17.1, MXLinux 17.1, Calculate Linux 17.12.2, and Artix linux all fail to boot graphically. At least antiX and MXLinux could still boot to console. Ubuntu couldn’t make it that far with a series of dramatic kernel panic messages relating to my CPU.
After about 2 days’ testing time, I finally settled for Fedora 28. With the 4.16 kernel and Mesa 3d 18.0.1 drivers, everything was detected properly without additional configuration, suspend and resume worked flawlessly, and my backlight was finally working as acpi_video0 wasn’t the only driver available. Debian won’t have a stable 4.16 kernel for some time; for the time being, I’m staying with Fedora for the hardware support. I just wanted to post some of my testing results on this new hardware to draw some attention towards Ryzen mobile support on linux systems. I’ve lurked many years on these forums. Consider this my first contribution. Thank you anticapitalista, dolphin_oracle, fungalnet, fatmac, BobC, Xaver, greyowl, and the rest of the antiX/MX Linux Community. I appreciate your cumulative efforts over the years!
