Jan-Michael proposed mounting it in the sandbox in https://github.com/flatpak/flatpak/pull/3727, but this was rejected upstream. This means WebKit sends a desktop user agent even if a mobile user agent is required. 1700997 1 alicem 2020-10-23 07:03:58 -0700 Hmm right. Can we access hostnamectl somehow? 1701006 2 mcatanzaro 2020-10-23 07:56:33 -0700 I'm not sure what would be acceptable for upstream flatpak. My guess is a chassis type portal would probably be acceptable. We should figure out what upstream is willing to accept before we implement something. 1773748 3 mcatanzaro 2021-06-30 08:11:37 -0700 Note this bug is really specific to flatpak only. It's not a problem for our bubblewrap sandbox because all of /etc is available in the bubblewrap sandbox. 1919141 4 mcatanzaro 2022-12-14 05:59:18 -0800 We were discussing this today. Instead of implementing a portal to fix the ChassisType check, we should instead delete the code and stop using chassis type. Currently it's only used for setting a mobile user agent header. Instead, we should check window size and touchscreen presence to decide whether to pretend to be a mobile device. However, WebKit itself does not have enough info to decide whether we are in mobile mode because it doesn't know what window size the browser uses as cutoff to switch between mobile UI vs. desktop UI. So I'm not sure quite how to do this. Some new API will probably be needed. 1919142 5 alicem 2022-12-14 06:01:24 -0800 From my pov the ideal would be to just a flag to opt into using mobile UA for a particular tab. That's how it works in basically every single existing mobile browser, incl. Safari on iOS. Then the app can figure out if/when to show an option for it - e.g. when the window is small. 1926782 6 kdwkleung 2023-01-19 17:46:42 -0800 https://gitlab.gnome.org/GNOME/epiphany/-/issues/1951
