The original idea behind this change (described in ticket #11064) was to
improve the assertions to avoid that users of the X server accidentally
forget to configure a DM or WM.
However this caused several issues with setups that require X, but no DM
or WM. The keymap testcases became instable as well as now disabling DMs
needs to be done explicitly.
(see https://github.com/NixOS/nixpkgs/pull/31268#issuecomment-347080036)
In the end the idea behind the change and #11064 was obviously a
mistake, so reverting it completely for now should be fine.
Commit 1f2b938 introduced a module for evilwm as a window-manager, but
did not actually add this module to window-manager's default.nix which
renders it useless.
Sawfish is a versatile, Lisp-based window manager
In that commit I include all Sawfish stack:
- librep, a lisp system;
- rep-gtk, bindings for gtk
- sawfish, the window manager
This commit updates the stumpwm to version 0.9.8. Futhermore, it
refactors the expression quite a lot:
* stumpwm has been moved from lisp modules to window-managers.
* stumpwm has been added to the window managers NixOS knows about, this
enables the user to add stumpwm as a default window manager in his
NixOS configuration like with Xmonad or i3.
* the package has been split into stumpwm and stumpwmContrib. This is
due to the fact that development of stumpwm and its extension modules
has been split into two repositories. As of today, the release is the
last one before this split. This split into two packages only reflect
those upcoming upstream changes already.
It is planned to make the addition of the extension modules voluntarily,
like with Xmonads option "enableContribAndExtras". Furthermore it might
be possible to add an option to compile stumpwm with clisp instead of
sbcl.
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.
