I have tried some things to change the first day of week to monday. But, first of all, locale doesn't seem to work. I tried
$ sudo export LC_TIME=en_GB
but it gives error.....
bash: warning: setlocale: LC_TIME: cannot change locale (en_GB)
The locale I uncommented is se_SV.UTF-8, and that should have monday as first day of week.
$ locale
LANG=C
LC_CTYPE="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_COLLATE="C"
LC_MONETARY="C"
LC_MESSAGES="C"
LC_PAPER="C"
LC_NAME="C"
LC_ADDRESS="C"
LC_TELEPHONE="C"
LC_MEASUREMENT="C"
LC_IDENTIFICATION="C"
LC_ALL=
How can I fix this? Mostly just want the first day of week to be monday and also for it to use metric system as default.
apart from localtectl you can look at https://wiki.archlinux.org/index.php/Locale
Ok, so I tried many things and had apparently missunderstood how locale worked this entire time. Because I almost gave up I tried things I did not expect from there.
My missunderstanding was that the locales have to be uncomented to be exported in /etc/locale.conf and that locale-gen did not export /etc/locale.gen as my default locale.
After enabling the locales in locale.gen, running "sudo locale-gen", then I could edit the locale.conf file with the locales I enabled in locale.gen. Changed that and rebooted.
