Nowadays however, atomic modesetting is very much the norm - and support in userspace for non-atomic drivers is starting to bitrot a bit - leading to its own set of issues. At the same time, many of those issues are fixed by just turning on atomic in nouveau. Plus, I've been running nouveau with atomic modesetting on by default for most of the machines I work on, and I've already fixed quite a number of issues to the point where things seem quite stable (excluding a single screen flashing bug on my desktop, which I am not particularly convinced has anything to do with atomic modesetting). This patch series enables atomic modesetting by default, at least for NV50 and newer. NV04 is left unchanged, as atomic modesetting was never implemented for it. This series also enforces leaving atomic modesetting disabled on
