Can't get 4k @ 60 hz with nouveau Open Source but NVIDIA "unfree" driver works

gr flag

Using the nouveau freedom driver xrandr lists 4k @ 30hz as maximum compatible resolution on DisplayPort.

With NVIDIA "proprietary" driver it magically does 4k @ 60hz out of the box, no config needed.

Tried forcing custom resolution:

$ xrandr --addmode DP-0 "3840x2160_60.00"
$ xrandr --output DP-0 --mode "3840x2160_60.00"
# monitor throws "No Signal"

Nouveau does work on HDMI @ 4k 60 but not DisplayPort.

Is DP 1.2 specification a limit of nouveau forcing users to unfree for using DP 1.4 on NVIDIA cards? Or is there a known workaround for 4k60 on DP?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
