Acer Chromebook R11

Out of the box everything works except no touchscreen support. I had done google searches trying to solve this since I first installed Q4OS Gemini in 2023. I briefly moved to Linux Mint XFCE which did have touchscreen support, so I knew it was possible. Today I asked Perplexity "What driver do I need for the touchscreen on an Acer Chromebook R11 running Debian 12". The answer "Debian 12 (Bookworm) ships with kernel 6.1 by default, but touchscreen support for Chromebooks like the R11 (codename CYAN) requires kernel 6.6+ for native driver inclusion"

The solution "Update the Kernel via Backports".

sudo apt install -t bookworm-backports linux-image-amd64

Reboot and verify with uname -r (should show 6.6.x+). Mine shows 6.12.9.

Before I could get this to run without error I needed to uncomment a line in etc/apt/sources.list.d.

deb http://deb.debian.org/debian bookworm-backports main contrib non-free-firmware

All is working well without installing anything else. There was other instructions to install additional drivers but they do not appear to be need in my case.

Q4OS Aquarius Plasma is ideal for the eol Acer Chromebook R11.

Re: Acer Chromebook R11

Thats interesting as I  have a friend who uses the R11 with Q4OS 5.7 and is running the stock 6.1 kernel. The R11 was released in 2016 so it surprises me that a 6.6 kernel was needed to get touchscreen support. He didnt have any issues with his touchscreen.
