set port I2C5 pull none

Thank you again for this sharing, I've also noticed that secure boot is now set on customised. ( Like when I've received my tablet. )
I think I's can be for Ubuntu compatibility but I'm not sure.

The problem is not in ubuntu
The problem is in unsupported GRUB version


Replacing grub with right one removes the problem totally

Hi,
I received my tablet two weeks ago and it has the BIOS version I2W6_AP135.037. According to S/N (1707XXXXX) its date is 17/07.
I bought the tablet thinking I could have a dual boot system with Linux. Following a Linux installation guide for this device, I tried to flash BIOS to v1.16 so I could have dual boot, but I had no success because of an "different hardware" or some similar message appeared (no info exists about the new BIOS version on the net and by the forums I though 1.16 was the latest version so I thought I was upgrading the older firmware).
Only later I found the option for OS selection (Linux/Windows) existed in my BIOS, so I tried and installed Ubuntu directly, with the default GRUB2, and it runs OK, except for the touchscreen (and maybe some other hardware, I didn't try extensively as I'm not interested if touchscreen doesn't work)
I tried also with Kubuntu (both 16.04.3 LTS and 17.04) with same success. Not even manually loading the goodix module worked (it's not loaded automatically at startup).
I was waiting for more info from experts to appear on the net about this new version I have so I could have a fully functional dual boot system when I saw this thread.
I'm glad to give you info about anything you want to know, specially if it helps other users with the same problem.

Hi

you have, my guess, 3rd hardware revision of Hi13 with different touchscreen sensor and for sure it is not goodix one. So you have to check if linux has a driver for it.

It seems that bios 1.16 doesn't properly work on tablets with 1.12-1.14 bios. So one could guess that there are 3 HW revisions:
1 - initial, with bios 1.12-1.14
2 - small hw changes (guess some updates on I2C ports), at least it breakes autorotation functionality on tablets with older bios
3 - newest one, different touch sensor and internal storage

From what I can see it looks like a new version from same manufacturer. I couldn't find information about it yet.
