Can you bisect? I'm not familiar with git, but I can try to learn how to do that. I'll tell you! For now, I just can say that the problem appears to have started with an update providing: - Linux kernel 4.3.0-3 - xf86-video-amdgpu ~git20151105 - xf86-video-ati ~git201501122 everything being obtained on openSUSE repos. (Sorry if this is only a very rough information.) FWIW, xf86-video-ati is irrelevant for Tonga. (Probably won't help much, but the problem is still present with kernel 4.4.0 and the latest version of amdgpu. For the bug itself, I also forgot to mention that the mouse pointer leaves trails all over the screen.) I also add a link to a bug submitted by someone else on bugzilla.opensuse.org, so the bug can be confirmed. Please attach the Xorg log file and the output of xrandr when the problem occurs.

Does the problem persist if you actually use xf86-video-amdgpu (preferably a newer snapshot than from last November)? Thanks for your answer. Yes, the log is quite strange about that, since xf86-video-amdgpu is indeed installed, but doesn't seem to be found... (Is there a way to 'force' the use of amdgpu?) Btw, the problem occurs even with a Live USB of the latest snapshot of openSUSE Tumbleweed for example (with kernel 4.4.0-2 too), so it should be easily reproducible by owners of Tonga GPUs. (Well... I hope the problem is not openSUSE-specific...)

Maybe 10-amdgpu.conf isn't installed in /usr/share/X11/xorg.conf.d . > (Is there a way to 'force' the use of amdgpu?) Yes, you can force it in Section "Device" in /etc/X11/xorg.conf . If there is no such file yet, creating it with only something like this should work: Section "Device" Identifier "Device0" Driver "amdgpu" EndSection Created attachment 200391 [details]

Can you find out what changed in 4.3.0-3 compared to the previous kernel you were using that worked OK?

Even when booting with old kernels that should have worked fine (e.g., 4.2), the problem persists... 2. We found (Comment #10) that amdgpu was not found/activated during boot: when 'forcing' its use by creating this /etc/X11/xorg.conf file, everything is OK, with all kernels I have tested (4.4, 4.3, 4.2). To put it in a nutshell, no matter the kernel we use, we have the same behavior: it works if and only if we add this /etc/X11/xorg.conf file. Maybe an Xorg autodetection problem that doesn't come from the kernel itself? (Is it possible?) (In reply to Fred Santos from comment #14) > 2.

If /etc/X11/xorg.conf.d/10-amdgpu.conf / /usr/share/X11/xorg.conf.d/10-amdgpu.conf isn't enough, then it sounds like maybe the amdgpu kernel driver isn't loaded yet the first time Xorg starts up during boot. Also, it sounds like there's a bug in the Xorg modesetting driver causing the artifacts you described. Probably no kernel bug here though. |
