Don’t worry about it. We don’t think that.
My reply lists the commands step by step, unfortunately I cannot be anymore clear than that. Make sure you type everything as I suggested (except of course [user@dom0 ~]$
which was just to show you where the command begins).
Open the terminal and type every command I listed here, in order: Dark theme - #4 by BEBF738VD
Why don’t you begin by checking the contents of the files you created with my commands?
Type the following in a terminal in dom0:
[user@dom0 ~]$ cat $HOME/.gtkrc-2.0
And check if the output is the same as below:
include "/usr/share/themes/Arc-Dark/gtk-2.0/gtkrc"
style "user-font"
{
font_name="DejaVu Sans Book"
}
widget_class "*" style "user-font"
gtk-font-name="DejaVu Sans Book 12"
gtk-theme-name="Arc-Dark"
gtk-icon-theme-name="gnome"
Then type:
[user@dom0 ~]$ cat $HOME/.config/gtk-3.0/settings.ini
And check if it matches the following:
[Settings]
gtk-font-name=DejaVu Sans Book 12
gtk-theme-name=Arc-Dark
gtk-icon-theme-name=gnome
Finally, verify this last file:
[user@dom0 ~]$ cat /etc/environment
Which should have the following line:
QT_QPA_PLATFORMTHEME=gtk2
Remember, everything matters: dots, dashes, underscores, and letter casing.
