Linux on the RCA Cambio 10.1 Tablet

Model #W101V2

Distro support

Generally any Linux distribution will work with some alteration. Very few distros currently work out of the box on this tablet due to the use of a 32 bit firmware on an amd64 Atom CPU.

./isorespin.sh -i ubuntu-18.04.4-desktop-amd64.iso --atom

dd if=linuxium-atom-ubuntu-18.04.4-desktop-amd64.iso of=/dev/sdc bs=4M

  • Void (needs custom ISO)

    Need to create the custom ISO with Void's mklive and PR102

  • OpenBSD, not a Linux distro but includes support for bootia32.efi on the install media (install61.fs).

Linux larry-W101-V2-TH2 5.3.0-51-generic #44~18.04.2-Ubuntu SMP Thu Apr 23 14:27:18 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

Configuration

By default the RCA Cambio runs in portrait mode, but before booting you'll want to add video=efifb fbcon=rotate:1 to your kernel command line.

I needed to set vga=normal to disable the frame buffer on boot.

Linux Kernel 4.11 and higher is needed for DRM video acceleration.

To turn off screen rotation there are simple instructions here https://askubuntu.com/questions/1035209/how-to-turn-off-screen-rotation-in-ubuntu-18-04-lts and here https://askubuntu.com/questions/1083870/automatic-screen-rotation-problem-on-ubuntu-18-04

I edited /etc/default/grub to rotate the screen during boot and remove the quiet and splash screen.

GRUB_CMDLINE_LINUX_DEFAULT="video=efifb fbcon=rotate:1"

I also added

$ cat /etc/xdg/autostart/screen.desktop

[Desktop Entry]

Name=Name
Exec=/bin/bash -c "xrandr -o 3"
Type=Application

To roate the X window on login.
