Back in January, I picked up a Lenovo Miix 310 a while back to play with Windows. It was an interesting experience, but I really can’t see myself shifting my development over to Windows any time soon, so I figured I’d throw Xubuntu on it and see if it’d be good as something I could use when travelling.
My first attempt was with 16.04 LTS. That didn’t go too well. The biggest issue was with screen distortion: the graphics looked interlaced. HDMI out worked, however, but I couldn’t get much further with it.
I figured I’d try 17.10, which might have slightly better luck, and it did!
While during boot, the same weird interlacing thing happened, I was able to get
to the point where I had a login screen, albeit one that was rotated, along
with the mouse pointer. To fix that, I made the following update to
sudo update-grub afterwards:
I then edited
/etc/lightdm/display-setup.sh, which I made executable:
#!/bin/sh # Fix screen rotation on login. xrandr --output DSI-1 --rotate right # Fix mouse. xinput set-prop "FTSC1000:00 2808:1015" --type=float "Coordinate Transformation Matrix" 0 1 0 -1 0 1 0 0 1
Then I did my usual setup:
apt install git tig ansible most vim-gnome tmux meld apt install debfoster zsh keepassx make openssh-server fonts-inconsolata ssh-keygen -t ed25519 -f ~/.ssh/id_primary chsh -s $(which zsh) mkdir projects cd projects git checkout firstname.lastname@example.org:kgaughan/dotfiles/ cd dotfiles make install
This would work in fits and start. Sometimes, I’d be able to boot it up without any issues, while other times I’d be presented with a black screen. At that point, I gave up, and the tablet was left sitting on a cupboard in my living room for a while. I suspected it was an issue with not being able to control the backlight, but didn’t know for sure, or how to solve it.
Recently, however, I came across
this post on the Lenovo forums
that gave me the missing part of the puzzle. I edited
pwm_lpss_platform, and ran
sudo update-initramfs -k all -u.
A reboot later, and everything’s been working almost flawlessly! There are still a few issues, such as the SD card reader not working (which I believe won’t be an issue in 18.04), and the Bluetooth support being broken, but I can live without those. The other small issue is that sometimes the device will hang for seemingly no reason.
