2200u with Vega 3

[veggis]

So I recently bought an Acer Aspire 3 2200u with Vega 3. Installed debian on it, and everything seemed to work fine, except the screen brightness controll. I've installed nonfree linux firmware. I've tried changing GRUB_CMDLINE_LINUX_DEFAULT parameters with different combinations of acpi_backlight and acpi_osi. I tried directly changing brightness from '/sys/class/backlight/acpi_video0' (there's no other directories), and that didn't do anything, either.

I tried upgrading to testing, but that wouldn't even boot. (It stopped at "acpi AMDI0010:01: already enumerated").
I'm a total linux noob, but I suspected it had something to do with graphic support.

Then I updated from kernel 4.9, to 4.19

At first it didn't boot, but after adding 'pci=noacpi' to grub (as discussed here https://bugzilla.kernel.org/show_bug.cgi?id=200087), it booted (also booted with 'ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 spec_store_bypass_disable=on' but yield no different result). I installed firmware-amd-graphics, and it froze on boot again. Also i noticed alot of tearing before rebooting.

I also tried a live image from https://download.clearlinux.org/image (clear-x-live-desktop-beta.img.xz) but that froze on boot aswel.

Does anyone have any succesful experiences with Ryzen+Vega?
Suggestions are appriciated

Might need even more backports...can you try booting a Live USB of MX Linux, which is on a Stretch base with a load of backports already, to see if that works? I'm thinking you need the newer Mesa from backports.

Ok! So i booted up with MX Linux from usb. It froze on boot at first, but i suspected adding pci=noacpi to grub would work. And it did!
After that, everything seem to work out of the box! I can adjust brightness and everything (even though i had to echo brightness in amdgpu_bl0).

Now.. How do I go from here?

How do I go from here?

Either install MX or install Debian and use the same backported packages.

Find out exactly what the packages are with

Code: Select all

# apt install apt-show-versions
apt-show-versions | grep backports

Instructions here: https://backports.debian.org/Instructions/

After further inspection, I see there's still alot of problems. The machine does not shutdown properly (stays at a loading screen), hibernation makes the screen black and does not boot up again, reboot does the same thing, it shutsdown but screen goes black even though the machine is still on. This probably is because of ACPI.

[stevepusser]

Are there any BIOS updates for that machine? Ryzen support seems to be flaky in Linux with many earlier BIOS versions. We also added a bunch of Vega firmware to the non-free firmware in MX that Debian hadn't yet, though that's fixed now in Debian testing, the MX test repo, or my own OBS backports repo below...not yet in stretch-backports ATM: https://packages.debian.org/buster/firm ... d-graphics

And yes, all those problems in MX are due to to turning off acpi, so you need to have it enabled somehow. There are many other tweaks available at boot, such

Code: Select all

acpi_osi="!Windows 2015"

, so you may have to search the web to see if anyone with the same hardware has found a solution yet.

I do have the same hardware backports as MX Linux has in a separate OBS repository, which is a bit easier to use, since it doesn't have the low pinning that stretch-backports has, plus includes the non-free packages.
