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.
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!
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?
