Running Ubuntu on Chuwi Hi10 Pro tablet

Chuwi Hi10 Pro (CW1529) tablet is sold for about $200 with an attachable keyboard, which makes it a potential candidate to replace my old Acer Aspire One and run Linux on it. It’s also equipped with a high-quality 10″, 1920×1200 IPS screen.

The tablet is based on Intel Atom x5-Z8350 Cherry Trail CPU, which requires a fresh Linux kernel. So I started with pre-release of Lubuntu 17.04 (Zesty Zapus).

So far, out of the box:

  • screen is oriented vertically, which makes it difficult to operate with the keyboard.
  • Touchscreen, sound, Bluetooth, and Wifi are not visible to the kernel.

Solving the screen orientation:

In /etc/default/grub, edit the following setting:

GRUB_CMDLINE_LINUX="fbcon=rotate:1"

Then, add the following to make lightdm rotate the screen automatically:

cat >/etc/lightdm/chuwi_hi10_screen_orientation.sh <<'EOT'  #!/bin/sh xrandr --orientation right  EOT  cat >/etc/lightdm/lightdm.conf.d/50_chuwi_hi10.conf <<'EOT'
[SeatDefaults]
display-setup-script=/etc/lightdm/chuwi_hi10_screen_orientation.sh
EOT
# this will apply the setting immediately:
systemctl restart lightdm

There is one bug though: for some reason, the display manager still thinks it’s the old resolution, e.g. 1920 on vertical resolution,  so all fonts look much smaller than they are, and window closing buttons are hardly visible. If I start lightdm without my customization and login, and then run “xrandr –orientation right”, all fonts and window controls are of normal size.

With Hopkins Kong’s kernel patches, Wifi adapter is now working. Touchscreen is responding, but acts randomly.

Things broken in Ubuntu 12.04

a list of annoying things that stopped working for me after upgrade:

  • Nokia 3G stick is not recognized (Bug #992639).
  • some ACPI problems on Acer AspireOne netbooks: now shutdown or reboot hangs much more often.
  • If I set the power manager not to suspend the netbook when the lid is closed, that applies to my session only. If no-one is logged in, the netbook suspends on lid close, whatever I tried.

Git repository with HTTPS write access

(this is to document a setup which was not used in the end, and was replaced with gitolite)

1. Rent a VPS. For example, at TOCICI a minimal VPS costs as little as $33 per year. The following tutorial is tested with Ubuntu 11.04 on such a minimal VPS.

2. Install and configure Lighttpd

aptitude install git-core lighttpd
