I'll give that a try. Just a note: .xsessionrc is debian-specific IIRC -- Best regards, Andrew Tropin signature.asc Description: PGP signature

So it appears that the SDDM service needs to be tweaked to use xinitrc or such. It appears that SDDM supports xinitrc files, but it looks for them (see data/scripts/Xsession) in $HOME/.xsessionrc and /etc/X11/xinit/xinitrc.d, which do not exist in Guix. There is no option for overriding the xinitrc. However, it is possible to override the Xsession script used, so we can give SDDM a modified Xsession script that uses Guix' xinitrc. I'll give that a try. Greetings, Maxime OpenPGP_0x49E3EE22191725EE.asc Description: OpenPGP public key OpenPGP_signature Description: OpenPGP digital signature

retitle 56661 SDDM does not do the equivalent of 'login shell --login', unlike other login managers thanks A digged a little, and found that: For GDM, things work, for SDDM, they don't. There is a 'xinitrc' procedure in gnu/services/xorg.scm that generates a configuration file that has a fallback .xsession that does a --login.

I'm not sure how your login/display manager works, but for X11 session
sourcing ~/.profile from ~/.xsession should do the trick.
Put the following content to your ~/.xsession:
--8<---cut here---start->8---
. ~/.profile
--8<---cut here---end--->8---
Or add the following service to your home environment:
--8<---cut here---start->8---
(simple-service
'xsession-init-file
home-files-service-type
`((".xsession" ,(plain-file "xsession" ". ~/.profile"
--8<---cut here---end--->8---
Tweaking .xsession was not necessary in my previous Guix System without
Home setup, so this seems like a work-around to me, not a solution.
However, possibly this is a bug in the setup of the login manager I used
(previously I used another one), so I will try a different login manager
as possibly Guix Home is not related here.
They do. Also, shouldn't ~/.bash_profile point to
~/.guix-home/files/.bash_profile instead of directly to the store, to be
more atomic (unrelated to #56661 though), like done for symlinks in /etc
in Guix System?
No.
Activation is not atomic process anyway.
I know it is not atomic. That's the issue I noted, an issue that seems
to have a partial solution I also noted.
With current file system APIs, it cannot be made fully atomic, but as
done for Guix System things, it can at least be made _partially_ atomic
-- i.e., when no files are added or removed relative to the previous
generation, the symlink switching is atomic.
(A form of 'Perfect enemy of the good' -- if perfect (= 100% atomic)
cannot be found, then that's no reason to throw away good (= mostly
atomic).)
(Also an instance of is-ought: it is not atomic, but that doesn't mean
it should be non-atomic.)
Greetings,
Maxime.
