[Nix-dev] Gnome 3.22 hit master

[Alexander Ried]

Hi,

With today's merge of staging to master, gnome 3.22 was merged. gnome3 now
defaults to gnome3_22.


GDM was finally updated from ancient 3.14 to current 3.22 and now uses
wayland instead of X for the login. After logging in, gnome-session will
likely still start a user X session for you (no more X running as root).


Note that the gnome modules changed in a backward-incompatible way.
For gnome users this means: if you have environment.gnome3.packageSet
manually defined to gnome3_20, please remove this line or your grapical
environment will be broken.


Sadly I have not yet found time for a proper fix for
https://github.com/NixOS/nixpkgs/commit/c2922a9157a8d8db62cee763e254113c3766461e
This commit affects all users of X and may enabled TCP, so it should be
fixed as soon as possible.
Probably the fix is easy: reenable the commented options and override
xserverArgs from the gdm module.
If someone want's to take care of it, please do.


Please report any breakage or general feedback on the mailing list or in
https://github.com/NixOS/nixpkgs/issues/19896

Thanks
