KnownIssues

This project is no longer maintained. You might be interested in Ubuntu Touch though.

Known Issues

Please note as of 12/7/2012 we strongly urge users to push to Raring 13.04

Fastboot failures

Occasionally, Fastboot will fail to run a command. If this happens, the installer will fail gracefully, and tell you to restart. The best way to get around this is to unplug the tablet, reboot into fastboot mode, plug back in, and run the installer again.

Low memory

In 13.04, the Nexus 7 is targeted as a development reference platform for the express purpose of optimizing Ubuntu core for CPU consumption, memory pressure, and power consumption.

By default, the desktop consumes too much RAM which can lead to crashes due to out of memory conditions.

If you are not a developer and simply wish to experiment with the Ubuntu desktop on the Nexus 7, you may wish to enable zram compression to slightly improve performance. To do so:

sudo apt-get install zram-config

and then reboot.

Warning /!\ Please Note: Enabling this will prevent you from helping us identify and resolve these issues. If you want to help make things better, do NOT enable zram compression Warning /!\

Sound

Sound does not work immediately upon boot. However, it does work after a suspend/resume cycle.

Bluetooth

Other

All ubuntu-nexus7 bugs.

Differences from Stock 13.04

The image is not preconfigured, so the user will have a desktop like experience after flashing. The user will configure their own username/password

We have merged many of the Nexus7 related packages into the Raring PPA so there is no need to add the public PPA as done with 12.10.

  • kernel image
  • firmware blobs for Broadcom WiFi and Bluetooth -- Awaiting Bug# 1087562

  • nvidia-tegra3 package tweaked to work around a library loading problem
  • patched Unity and Nux to work around a Tegra3 driver limitation


This heading below is specific to the Initial Release Nexus7 Image, 12.10

Differences from Stock 12.10

The image is a preconfigured ext4 filesystem image, so no installer is being run. The default user/pass are ubuntu/ubuntu and this user gets logged in automatically. The hostname is nexus7-$SOME-RANDOM-WORD to avoid naming collisions in the network.

The extra package changes and additions reside in a public PPA. These include:

  • kernel image
  • firmware blobs for Broadcom WiFi and Bluetooth

  • nvidia-tegra3 package tweaked to work around a library loading problem
  • patched Unity and Nux to work around a Tegra3 driver limitation
  • default settings for sound, autologin, etc.

While the image is aiming to be close to stock ubuntu-desktop, some packages are not included:

The rhythmbox-ubuntuone package is removed as it causes rhythmbox to crash on startup. LibreOffice and Thunderbird are removed in order to decrease the image size.
