I have a Dell Chromebook 11 (3189). So far basically everything works on arch (using LTS kernel, and latest MrChromebox Bios update as of this post.)
But all the methods I have tried to look into just straight up dont work for two in one conversion on the hinge, it detects when closed, or open, but not if its flipped over.
I want to disable the keyboard input when its flipped over, rotate screen 90 degrees, and show an onscreen keyboard below the task bar (currently on KDE plasma, wayland, can go to x11)
It works on my Jinlon, so it should work on your Chromebook as well. Are you using keyd? Sometimes keyd can cause issues with tablet mode. Also, I doubt X11 would with better than Wayland for this.
I am infact using keyd, have a custom accessibility map for the chromebook that gives me chromeos control keys while still being able to access linux stuff such as tty.
But issue was noted before I used keyd, it would act as if the lid had two states, not three, open, and closed

Ran into the same issue/output on my Eldrid device:

I did try to troubleshoot it w/ Claude (AI) before I jumped onto the forums, and part of the area it was directing me towards might be related?

Does this mean that the sensor’s .service file is erroring out, and that’s why the tablet mode switch functionality never is an option?
I don’t think so, since the tablet mode and lid angle is working on Jinlon without that service even existing.

I got nothin, I reinstalled with endeavor due to bloat build up and wanted to clean up things
AFAIK it should be done using TBMC.
My eldrid has broken screen so I can’t fully test it, but KOHAKU (CML) switches to tablet mode successfully - running Fedora/KDE/Wayland.
Shared the snippet w/ Claude (AI) and it redirected me to look to see if it was configured via grep CHROMEOS_TBMC /boot/config-$(uname -r).
This returned: # CONFIG_CHROMEOS_TBMC is not set
Which is promising because it insinuates that it’s in the current kernel and just deactivated. It gave me some advice, but before I go into the weeds, I just wanted a gut check that I’m not about to break something lol. Here is the AI response to finding that the config wasn’t set:
This is actually good news because it means:
Your kernel recognizes the CHROMEOS_TBMC driver option.
The driver is available but just not currently enabled.
You likely won’t need to add any new code to your kernel source; you just need to enable this existing option.
Next steps:
Enable the driver: You can enable this driver without fully recompiling the kernel. You’ll need to:
a) Use make menuconfig or make xconfig to access the kernel configuration.
b) Find the CHROMEOS_TBMC option (likely under Device Drivers > Input Device Support).
c) Enable it (change from to [*] or [M] for module).
d) Save the configuration and compile only the new module.
Load the module: After compiling, you can load the new module with sudo modprobe chromeos_tbmc.
Make it permanent: Add chromeos_tbmc to /etc/modules to load it at boot.
My ELDRID successfully switches to tablet mode if I flip it, but of course no touchscreen for me. I think it’s working, @ninelore can verify as his ELDRID is in working condition
Yes, Debian is missing a lot of necessary modules - so does Ubuntu, that’s why we generally don’t recommend those distributions as you need to build your own kernel.
