I have yet to narrow down the exact conditions, but this problem has existed across different kernel versions on Fedora 42 and 43, so I’m unsure if it’s an OS or Framework hardware issue; however:
Frequently, when in “tablet” mode, I can’t get the onscreen keyboard to display when clicking/touching/using the pen on in an input, trying to sign in after X-minutes of inactivity and auto-locking of the desktop, and even if I open the laptop back up into “laptop” mode and then back, it’s a 50/50 shot whether the onscreen keyboard will display.
I do frequently use the Framework pen and Xournal++, so I’m not sure if there is some confusion or issues related to a connected stylus.
No trouble here with Debian or Windows 11. But I’ve only be using it for 2-3 days. Might want to try another OS or a clean install of Fedora. Easy to do if you have enough disk space and can set it up as a dual boot system.
FWIW I did experience some funky behaviors before updating the BIOS & Debian, and loading the FW driver bundle in Windows. After that everything was fine.
GNOME’s built-in OSK has exactly the problem you describe, even on other hardware (Star Labs StarLite Mk. V tablet). The “fix” is to use a different OSK or a different desktop environment.
