Video card help

English Hardware

Hi,

I have an nvidia video card.
I am tired with the problems with nvidia driver. I do not want proprietary stuff no more.
I am reading from few days.
Nouveau driver is a little buggy. Nvidia did not help the mantainers at all.
Wayland is another problem. Nvidia was a big problem with wayland. Maybe in gnome will be solved sometimes but in KDE will not (until nvidia will be offer a patch).
I never had an AMD (ATI) video card. Only nvidia.

From what I read there is no big problems with amdgpu, wayland and kde (gnome). It should work.I would like to hear an opinion from a AMD video card owner.
I really appreciate any help.

Thank you.

Hello,
Welcome to the openSUSE forums…

Have you tried just running openSUSE to see how it runs on your hardware?
Here, next is the location of the LEAP 15 LiveCD images, you can run these from a CD or USB stick instead of installing on your main system disk. You’ll notice you can choose between KDE and Gnome.

https://download.opensuse.org/distribution/leap/15.0-Current/live/

By default, you’ll be running the nouveau driver, which should be fine for most Users. If you have a special need to install the proprietary nVidia driver, there are recommended procedures published as SDB

https://en.opensuse.org/SDB:NVIDIA

openSUSE is one of the leading distros of choice if you want to run Wayland, for both KDE and Gnome, you simply disable automatic login so that on the screen where you login, you choose the Desktop with or without Wayland.

If you have further questions or run into an issue, you should post in the regular Technical Help forums instead of this one, since questions in this Forum are generally those that don’t fit into those.

HTH,
TSU

Hi
I have three laptops running amdgpu (for awhile now infact, built my
own :wink: ) they are only Mullins R3, R4 and R5, There are some issues
with wayland and my touchscreen system (DELL Inspiron 5555) the other
two are running X11 due to my use of synergy and no wayland support yet
(but coming soon…).

So I would check the applications your planning to use and see where
they are at else stick with what you have and X11?

Thanks for your answer.
I did not have any applications than a standard one (I mean no touchscreen, no synergy etc.). No games.
My problems: I have a Ryzen CPU. With new kernels that CPU become better. With 4.17 kernel few problems of this CPU are gone. I installed 4.17.rc7 but nvidia driver not works. I suppose that if I will try new kernels I have problems with nvidia proprietary driver. Amdgpu will be not a problem because it is ships with the kernel.
If I understand well, wayland is the future. But there is a lot of problems with nvidia and wayland - nvidia wants to stick with EGLStreams.
I tried gnome with wayland, nouveau and kernel 4.17rc7. Works like a charm. Gnome-shell never bigger than 150 Mb.

I never had an AMD GPU (from 1995). In past there was some problems with AMD GPU and linux. It is a little hard to me to make the switch.
I only want to know if is there big problems with AMD video card and wayland?

Hi
Possibly the newer cards like AMD Vega… but those should run the
proprietary driver as well (too much hard work…) If I got a
standalone card of the AMD flavor it would only be a mid range one.

Thanks. That’s was what I was thinking. A RX 550 or 560 video card.

Hi,

I need a little help, please.
I change my video card. I have a RX 560.

linux-rnx8:~ # /sbin/lspci -nnk |grep -A3 VGA
0a:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Baffin [Radeon RX 460/560D / Pro 450/455/460/560] [1002:67ef] (rev e5)
    Subsystem: Sapphire Technology Limited Device [1da2:e348]
    Kernel driver in use: amdgpu
    Kernel modules: amdgpu

My problem is that screen is flickering. Only bottom of the screen.
I tried amdgpu.dc=1, amdgpu.dc=0 - nothing.

linux-rnx8:~ # cat /etc/X11/xorg.conf.d/20-amdgpu.conf
Section "Device"
   Identifier "AMD Radeon RX 560"
   Driver "amdgpu"
   Option "DRI" "3"
   Option "TearFree" "true"
EndSection

linux-rnx8:~ # cat /etc/X11/xorg.conf.d/10-amdgpu.conf
Section "OutputClass"
    Identifier "AMDgpu"
    MatchDriver "amdgpu"
    Driver "amdgpu"

Thank you.

Hi
What desktop environment(s) do you see this, are you running wayland or Xorg on the Desktop environment(s) is question?


echo $XDG_SESSION_TYPE"
9

Thank you.
Tumbleweed + Gnome

echo $XDG_SESSION_TYPE
x11

HDMI output.

10

There is the same flickering with wayland.

11

There seems to be numerous accounts online reporting similar flickering behaviour, and unfortunately not many describing definitive solutions.

Anyway, just in case setting the ‘AccelMethod’ is worth a shot, I wanted to share the following post with you…
https://bbs.archlinux.org/viewtopic.php?pid=1681512#p1681512
The OP decided to ditch Gnome as well. YMMV.

12

Since this thread has morphed in to a support thread, I’ll move it to the Hardware sub-forum.

13

Moved from ‘Looking For Something Other Than Support’ and open for posting again.

14

I happened to find a bug report and thread describing flickering behaviour with recent kernels where AMDGPU DC (display code) is enabled by default. Some users have found disabling it helps…

https://bugs.archlinux.org/task/58158
https://forum.manjaro.org/t/flickering-screen-on-amdgpu-with-new-kernel/44477/3

The following boot parameter can be used…

amdgpu.dc=0
15

Thank you.
amdgpu.dc=0 not work.
I search on ArchLinux forums. It seems that is a problem with amdgpu and hdmi.

16

Solution (not final).
It is fine with last kernel 4.17 and wayland.
But I need to change the refresh rate every time to stop flickering.

PS. I tried a lot of boot options (amdgpu.dc, amdgpu.aspm, amdgpu.runpm, amdgpu.dms…) but not work.

17

Well, sometimes such experimentation is necessary. Anyway, it reads you’re making progress. Thanks for the update.

18

You are welcome.
I hope that will help someone.
BTW, with DVI output no problems at all.

19

I’ve read of accounts where some users have apparently found that unplugging and re-plugging HDMI monitors have also worked. Not sure why that would cause such behaviour though.

The RX560 is around a year old, so may not have all the bugs pertaining to it flushed out yet.

There is another possible solution not mentioned in this thread. There is more than one competent FOSS userland driver for each of NVidia and AMD cards: modesetting, which is built into the server, and can be enabled as simply as uninstalling any other driver packages installed. Modesetting is the only driver I use with gfxchips it supports, which is most less than 8-10 years old and older than 6-9 months.

Another idea: is that RX560 using a separate power connector? Did the NVidia too? If yes to both, maybe the power supply is strained to keep up?
