  • This gets a bit messy. Here’s a python code snippet that gives you some idea what I’m up to with my Debian/Gnome desktop:

    if while_tweaking('all', 'default browser', '√'):
        ChangeSymbolicLink(
            name='gnome-www-browser',
            action='Make Tor the default browser.',
            old=f'~ccrhode/tor-browser_en-US/{TBB_SCRIPT}',
            new='/etc/alternatives/gnome-www-browser',
            )
        ChangeSymbolicLink(
            name='x-www-browser',
            action='Make Tor the default browser.',
            old=f'~ccrhode/tor-browser_en-US/{TBB_SCRIPT}',
            new='/etc/alternatives/x-www-browser',
            )
        ChangeGConf(
            name='http handler',
            action='Change default Gnome http handler.',
            path='/desktop/gnome/url-handlers/http',
            key_values={'command': 'gnome-www-browser "%s"'},
            )
        ChangeGConf(

            action='Change default Gnome https handler.',
            path='/desktop/gnome/url-handlers/https',
            key_values={'command': 'gnome-www-browser "%s"'},

    if while_tweaking('personal', 'desktop_icons', 'all', 'default browser', '√'):

    In other words, in place of your browser invocation, you want a script that applies the -new-tab option to the browser invocation and you have to correct a bunch of Gnome configs, symlinks, and MimeTypes to get that to stick.



  • GNOME is entirely adequate.

    Yes it is except when it isn’t. Maybe there’s a reason practically no Adwaita theme alternatives ship with Debian. Maybe not. But, using Gnome, it’s the default theme or nothing. I have to admit I don’t know from themes. However, there are lots of Gnome themes available from theme peddlers.

    Recently I became fed to the teeth with claws-mail, which is a GTK app. In Adwaita the foreground font color is too dark (gray) on top of the background highlight (blue). My eyesight had deteriorated to the point that I just couldn’t read the Subject of the current eMail, so I shopped for a new theme that would be … adequate. I didn’t have time to try them all.

    I settled on Ant by EliverLara. In this theme foreground font color (white) on background highlight (salmon) is just barely visible. I use it only for claws-mail:

    > env GTK_THEME=Ant claws-mail
