Mer on Nexus7
DISCLAIMER: This project is not endorsed or supported by any company. This is purely a community based effort.
This page describes the running Mer on Nexus 7 (see Community_Workspace/Tegra3 for common Tegra3 stuff).
The hardware adaptation is maintained in the project [1]
The Plasma active instructions are quite generic and can be easily adapted to other images as well.
Hardware Adaptation Status

Workarounds
Keyboard
If you have issues with the default keyboard you should give this one a try: To install it just:
zypper ar -G http://repo.pub.meego.com/home:/wonko:/branches:/Project:/KDE:/Trunk:/Testing/CE_UX_PlasmaActive_armv7hl/home:wonko:branches:Project:KDE:Trunk:Testing.repo zypper up maliit-active libmaliit-quick killall -9 maliit-server
Nemo Mobile
All the major things are working, including accelerated video, OpenGL ES, and window compositing.
Top issues
- FIXED: X.Org/VT problems, if the display blanks. Run "chvt 2 && sleep 1 && chvt 1" e.g. over ssh to recover.
- Tearing (doesn't seem to include video/OpenGL ES)
Hardware support
Accelerometer / Gyroscope
All files are in /sys/devices/platform/tegra-i2c.2/i2c-2/2-0068/iio:device0
mpu6050 (sensor in Nexus 7) configuration:
- configure buffer: "# echo 10 > buffer/length". 10 is choosen by me at random. -- Glueckself 23:49, 28 January 2013 (UTC)
- configure desired axes / values: "# echo 1 > scan_elements/in_*_en". This command has to be run on all desired values, "> in_*_en" is not a valid redirection.
- enable buffer: "# echo 1 > buffer/enable"
The data can then be read from in_{accel,anglvel}_{x,y,z}_raw.
Touchscreen rotation
There is a modified mtev driver that supports rotation (via the "Rotation" parameters).
Xinput <= 1.5.4 needs to be installed (>1.5.4 needs a newer xi library). xrandr/xinput values are: normal/3, left/2, inverted/1, right/0.
The UI can then be rotated via xrandr.
Please note that this doesn't support animations. There are also a few issues (half drawn background, some cursor issues).
