[DEV] Multiboot Linux on Infinity tf700 (project closed)

• Unity has some problems with performance and ram eating - this is place for optimizations.
• In-device microSD really bad works.
• WiFi disabling is fail bcmdhd kernel module.
• vt1-only, if you try to switch to vt* (`chvt 2`) - your device is freezes and reboot.
• To use unity you need nux-tools, libnux-3.8-0 and libnux-3.8-common with version 3.8.0-0ubuntu1nexus7.1 (this packages are hold)
• Sometimes I can see really bad artifacts with fonts and background on the device screen (mostly if using chromium browser). Only reboot fixes it.

  1. Wakelock to emmc
  2. Wake up: echo "on" > /sys/power/state or powerbutton (maybe with kernel patching)
• Totem - now is not working
  gstreamer-properties and set Audio->Output=Custom, Audio->Output->Pipeline="nv_omx_audiosink" and Video->Output=Custom, Video->Output->Pipeline="nvxvimagesink"
