    flatpak create-usb [OPTION…] MOUNT-PATH [REF…] - Copy apps or runtimes onto removable media

    I don’t think it has to be removable media despite the description. I’m also not exactly sure how to install the packages once they’re copied over.

    For more details, see flatpak create-usb --help and flatpak man pages.
























  • You can right now. If you are using KDE, it should work with mpv, though you might need to launch it from terminal with a few flags to tell mpv to use HDR.

    If you’re not using KDE, you can launch gamescope with the hdr flag in the tty and have it launch mpv.

    Though I’m not sure any browsers have working HDR. I think Chromium may have some stuff in progress. Gnome Web may get it since WebKit supports HDR and HDR is being worked on for GTK.




  • you can’t go and install apt packages without updating your system first

    You can use apt without updating first. You’ll just be installing potentially outdated versions if the cached repository information is old. Though you may run into issues if you do partial upgrades (updating the cached repository, but not running an upgrade, then installing something new). Though this is less of an issue on Ubuntu since they try not to do big updates.

    you also can’t use a GUI apt frontend as well as apt via the command line

    The error message should tell you that you can’t have multiple commands running at once. The error message is a bit too technical, citing the lock files.









  • True, although not in the same way. KDE is using its own GTK theme and uses ~/.config/gtk-3.0/gtk.css to override colors to the accent color. But this method is broken for sandboxed versions of Firefox since they can’t access ~/.config/gtk-3.0/gtk.css (though with flatpak you could create an override to allow it).

    I believe (and hope) Firefox is now following the standardized accent color portal for determining the accent color. If so, then this accent color change should work on Gnome, KDE, Pantheon, and other desktops that support the accent color portal. If true, then even sandboxed apps should follow the accent color without messing with the sandbox.
