After much struggle with all clients known to me, I now use Thunderbird.
I might not keep using it for a longer time, so I kept the old
configuration and disabled it, so it can be reused at a later time.
Because Thunderbird doesn’t support nice declarative configuration, I
don’t see much sense in configuring the accounts declaratively, when the
settings for the accounts (which is much more) have to be configured
manually.
This is needed for Intel Arc support (Mesa 22.3+).
This also makes changes so the nixpkgs system evaluates without
errors/warnings (caused by my configuration).
Things are not very smooth yet. Hwmon only works with Kernel 6.2 and
only supports energy monitoring (and even that doesn’t look too good).
Fan control and temperature is not supported. To get at least usage
statistics, intel_gpu_top can be used. Mangohud in its newest unreleased
version also supports getting stats from it. However, intel_gpu_top
needs cap_perfmon, which is a pain to get working inside the double
bubblewrap sandbox for steam, therefore it is not yet available.
On the positive side, OpenCL works well and oneAPI also works with
blender-bin from nix-warez (nixpkgs doesn’t yet have blender with oneAPI
support).
This replaces the default style sheet that gets overridden with a custom
one from scratch.
One thing that is still not ideal is that notifications with action
buttons have a scoll area for the action buttons, which shouldn’t be the
case.
After the update to the new Iosevka version, the font was smaller
horizontally on non-HiDPI screens. Increasing the font size by .5px
ensures a display that reproduces the behaviour of the old Iosevka
version on all screens I tested.
This does not use the home-manager provided account module, because it
does not support notmuch, LOGIN authentication and special characters in
user names.
