How am I supposed to edit Silverblue kernel arguments with a touchscreen?

Hello. I have Fedora Silverblue installed on a tablet, and I’m having a nightmare of a time trying to do something as simple as change the kernel arguments. I know it can be done via rpm-ostree kargs --editor. My problem is that I’m using a touchscreen, which means I’m using GNOME’s touch keyboard, which for some bizarre reason has no Escape, Ctrl, Alt, etc. keys.

Running rpm-ostree kargs --editor launches it in Vi. I can enter insert mode and make my changes, but then I have no way to save and exit, since I lack an Escape key!

Running EDITOR="flatpak run org.gnome.gedit" rpm-ostree kargs --editor launches Gedit, but with a blank file open, so there’s nothing for me to edit.

Nano isn’t installed by default, and I could install it temporarily (albeit with a reboot before and after), but as far as I know that needs the Ctrl key to save and exit, which also isn’t on the GNOME touch keyboard.

This seems very ridiculous. Am I missing something? Is there a simple way to change these kernel arguments without digging out an entire keyboard to plug into my tablet?

Thanks.

rpm-ostree kargs append=$1=$2
man rpm-ostree

Thanks. I did read the man page previously, which is how I learned of the --editor argument. For some reason I thought that was the only option it gave and didn’t go back and double check. Sorry about that! In my case I want to change an existing argument rather than append, but it seems --replace will probably do the job. Thanks again.

A GUI would be nice but kernel arguments maybe is not the usual thing that should be tweaked if everything is working properly (else it’s a bug).

Realise this is a late reply but this might help. There is an extension for an improved onscreen keyboard available via extension manager. Not sure it was there when this topic was originally opened. In the extension manager search for onscreen keyboard and it will come up. It’s a full keyboard so no fussing about. Hope this helps.
