Xorg.0.log with modesetting
I have 3 Dell WQHD Screens (2560x1440) screens, connected to a Radeon RX580
(XFX, RX-580 GTS Black Edition, 1425 MHz 8GB), running on Fedora 29.
My kernel is:
Linux edison 4.19.13-300.fc29.x86_64 #1 SMP Sat Dec 29 22:54:28 UTC 2018 x86_64
x86_64 x86_64 GNU/Linux
On 2/3 monitors I get periodic random black screens for 1-2 seconds. The
display comes back and all appears normal after this happens.
I have tried both with and without modesetting enabled. Nothing at all appears
in either the kernel log when this happens, or in Xorg.0.log. I have attached
complete Xorg.0.log's and the relevant parts of dmesg (from boot to the very
last drm-related message).
I was sure this was a hardware issue, and after a debugging process with XFX
support in which they had me swapping monitors and cables, they RMAed my card
and sent me a new one. However, the new card has very similar behavior (the old
card seemed to black screen only one monitor, the new seems to do two of them,
but in exactly the same way, and I have also updated my kernel and OS since
then, so its possible the hardware is completely unrelated to the minor change
in behavior).
Given the change in hardware, it seems likely to me this is a driver bug rather
than a hardware one.</pre>
