Hi,
I was given a bunch (10) of CB Drawcia / HP Chromebook x360 11 G4 EE.
I installed Fedora and my students (highschool) are quite happy with them.
Everything works except touchscreen.
Do you know if it’s possible to make the touchscreen to work ?
I tried other distribution like Ubuntu, Manjaro, PopOS.
Codename drawcia
Board Names dedede
SoC Intel Celeron N4500 Jasper Lake dual core @ 1.1 GHz
Thanks.
Are you using RW_LEGACY or full rom firmware?
I always used full UEFI rom firmware.
I can try to revert back to stock than go RW_LEGACY.
Is there a way to go full rom to RW_LEGACY directely ?
Thx
we don’t want you to go back to RWL, bc touchscreens are known to be problematic there due to Google’s fw / use of custom kernel extensions.
provide cbmem and dmesg logs from Linux please

Here my debug-logs.tar.gz from a fresh install, updated and with the audio script.
kernel 6.9.8-200.fc40
The touchscreen is not being detected by the firmware.
DRAWCIA has 4 different touchscreen options, and the firmware probes each during boot to see which (if any) is present. It’s not finding any. Are you sure the cable wasn’t accidentally disconnected when you opened the device to disable WP?
No the connector is connected.
Maybe I got a weird version of a Drawcia.
Even without touchscreen there are nice small laptop.
I will try to unmount the screen to see the touchscreen model.
The chip seem to be a Goodix GT7375P
that’s a valid option for DRAWCIA. no idea why the detection isn’t working though - might need a custom debug build to troubleshoot further
Thanks anyway for your time.
I will try to go deeper now that you told it’s a valid option.
I’m experiencing the same on my DRAWCIA-CFUL, though with Win11.
Thanks I’m not alone. I stopped looking at the problem thinking that was cause I have prototype models.
I will try in the week with the latest firmware and fedora 41.
Let us know if it works out for you then, as I have two of these I may donate to a library soon and it would be cool if that touchscreen worked.
no luck with fedora 41 and the newest kernel.
@s31bz @nico_fedora please provide cbmem and dmesg logs
My apologies. I have donated one of them and sold the other to a friend. Nico might be able to provide.
Hi,
here my logs.

It’s not on the latest firmware and as the WeirdTreeThing audio fix.
Thanks.
For enyone comming after. I got my hands on a drawcia x360 11 G4 chromebook a few months ago. managed to put full UEFI rom firmware thanks to instructions on this forum and instructions on mrchromebox.tech. (huge thanks btw).
Been trying to figure out how to use the touch every now and then screen since i was sure it worked in ChromeOS before flashing the device.
Turned out its just as simple as activating the GTCH7503 option in the boot options for touchscreen type input, and now it just works for me, i have not tried really to do anything else on this install, running EndeavourOS Linux but tried also on Manjaro boot disk.
TLDR: In boot menu option for “Touchscreen Type” - use GTCH7503 option.
Hi,
I didn’t had time to try out the new firmware and thought to change to new touch screen menu in the UEFI.
I’m glad to say everything works. Thank you MrChromebox.
Quickly my students updated the firmware of our DRAWCIA fleet. Many flashed bricked the startup maybe cause of Ubuntu 25.10. So they wrote the BIOS directly with the USB Programmer.
(they gonna build a shrine to MrChromebox).
