Trisquel on the OnePlus 6
I was shocked when I saw that Windows 11 can run on the OnePlus 6T. So I decided to try Trisquel 11 instead using the same method, shrinking the Android data partition. More work is needed to replace Android, I predict at least 5 years.
Just curious. Did you get Trisquel working? If you did, was it not a good experience and that's why you said it needs a lot more developing to make it a good experience or it doesn't work at all?
I did boot into a special UEFI/Linux kernel that exports the phones internal storage over USB to the host computer. Then I used gparted to shrink the userdata partition and created a new ext4 partition where I extract the Trisquel rootfs, which I downloaded from http://mirror.fsf.org/trisquel-images/trisquel-base_11.0.1_arm64.tar.bz2 to my computer. I also have a copy of the rootfs on my Talos II, which I use for software development. Now I have both lineageOS and Trisquel on my phone, was able to install phosh and apache2. But I'm still dependent on LineageOS and its Java based Android UI. My long term goal is to get phosh working.
That's really interesting. When you said 'More work is needed to replace Android, I predict at least 5 years.' you mend the user interface?
Regarding "My long term goal is to get phosh working.":
You could consider postmarketOS which offers Phosh:

OnePlus 6T is supported by the community:

But I want Trisquel so I do not switch to postmarketOS. But I may use parts of postmarketOS.
