[SOLVED]i915 problems with 2 external monitors(ultra dock)

I've set monitors to go to sleep after 10 minutes when i wake up my laptop one of the monitors fails to wake up.
Prints this out to journal/dmesg:

both monitors are connected with displayport cables.

Any idea what might be the issue here? Is this kernel or hardware issue?

when that happens i need to reboot. reattaching cables, powercycling monitor doesn't work. xrandr sees the monitor but trying to disable/enable it and/or change resolution ends up with freeze

Please help

Re: [SOLVED]i915 problems with 2 external monitors(ultra dock)

FWIW if only heard of that specific stack trace/error in conjuntion with the xf86-video-intel ddx. Are you currently using that? What happens if you remove it in order to use the built-in modesetting driver instead?

Removed xf86-video-intel, looks ok for now, thanks!

Re: [SOLVED]i915 problems with 2 external monitors(ultra dock)

That driver is in somewhat of a perpetual limbo, it's not entirely dead yet, but also really doesn't see enough activity in relation to the known issues it has and it has some functionality that might be more useful depending on your needs. FWIW as far as I know most of the intel graphics devs do more actively contribute to the modesetting ddx, and many of the more mainstream distributions have switched over.

If you are happy with that and intend to use it that way, please mark the topic as [SOLVED] by editing the title in your first post.
