According to testing on the issue, reverting the driver bumps from PR #153994 isn't needed to fix the issues. (There are no newer releases for -ati and -nouveau.)

However, there's a newer release of xorg-server-1.20.14, but the affected people haven't tested it (yet), so I can't be confident that it didn't backport the regression. (There is some modesetting change.) You can try https://github.com/vcunat/nixpkgs/commits/p/xorg-server_bump

We've been using 1.20.13 for a very long time and I don't recall people reporting problems, so I'd hope it would be OK even without doing more testing beforehand.

Can confirm reverting to xorg-server-1.20.14 is solving the issue for me.

With the amounts of rebuilds we should target staging-next at least.

[vcunat]

I assume .14 will be preferable to .13, so I added that here now, but more testing would still be nice.

I just switched to this branch, and I can confirm that this still works, whereas the latest nixos-unstable still triggers the issue for me. Thanks!

[vcunat]

I think we have enough feedback to stage this at least for unstable.

Successfully created backport PR #175320 for staging-22.05.
