Unfortunately, I don't know any more about the image than you do. Here's the virtualbox docs on graphics adapters.

Fixed - turns out I need the binder patch: https://github.com/moto-SDM660/android_kernel_motorola_sdm660/commit/d6d8b51485eaf02933055e2d201c338bca1020f6

It sounds like a graphics issue, have you tried using different graphics adapters?
There's no such things as a "standard IMG" - img files are usually just raw, byte-for-byte copies of disks or partitions, so it's the filesystem/partition table that defines them. You should be able to use dd to write it to a disk/partition. (Try running fdisk -l /path/to/img for more info on its contents!)

Hi everyone, I've been trying to port Ubuntu Touch to my Xiaomi Redmi K20 Pro (raphael), using Halium 9 with the help of the GSI.

I'm almost there - but LightDM crashes, because unity-system-compositor crashes.
Below is the contents of /var/log/lightdm/unity-system-compositor.log:

Does anyone know what's happening here?

@bluekenny I got KDE Plasma Mobile working with this kernel patch! I think Ubuntu Touch is broken with Halium 7.1, and CAF devices atm, though.

To merge the patch, cd into the kernel directory, and run curl https://github.com/Halium/android_kernel_oneplus_msm8996/commit/3e019b8700b36aef379846a748e3a447a8c3dbe7.patch | patch -p1

@bluekenny I think that's a different issue. KDE Plasma Mobile has a special CAF rootfs, and graphics don't work on that either.

Hey, I 'm also trying to port to this device, and I just saw this thread. I'm having the same issues as you - did you ever get the graphics working?

I'm trying to port Halium to the Xiaomi Mi 5s Plus (natrium). It has a Snapdragon 821.
I can boot Ubuntu Touch, Plasma Mobile, and the Reference rootfs. My problem is, on all three, I can't get anything to show up on the screen. the MI logo splash screen just stays there, even after the system has booted. I get these errors in the logcat: https://hastebin.com/zosonidaxi.sql

Edit: I got it working with this kernel patch!
