Greetings,
The system is Acer Aspire V3-772G with NVIDIA GeForce GT 750M and Intel graphics controller. I've set things up with the open source drivers as directed at https://wiki.archlinux.org/index.php/PRIME.
I get some nouveau errors after boot:
journalctl -b | grep nouveau

Should I worry?

Look at this:
Bug 70354 - [NVE6,NVE7] HUB_INIT timeout on graph init, blob fw doesn't help
https://bugs.freedesktop.org/show_bug.cgi?id=70354
And try proprietary drivers https://wiki.archlinux.org/index.php/NVIDIA

Looking at that bug I see the final comments reporting the same or similar errors as I'm getting, but there's no follow up for several months and I didn't find these errors mentioned elsewhere.
I may try with proprietary drivers at some point, but wanted to know the impact of the issue.
