tl;dr: I upgraded from 12.04 to 14.04. And now on boot up there's a wolf on the screen and says 'Ubuntu Kylin' and my touchpad doesn't work. How do I fix these issues?

I upgraded from 12.04 to 14.04 just an hour ago. I configured the update manager to show only LTS updates. Then I did "sudo apt-get install update-manager-core" followed by "sudo do-release-upgrade -d". It showed me that the updates are being pulled from 'trusty' version. When I restated after update I saw that boot screen is no longer saying 'Ubuntu' with those moving dots while booting, instead a wolf is there on the screen with text 'Ubuntu Kylin'.

Next, the desktop loads but my Touchpad is no longer working. I press 'Alt+ctrl+F6' but am unable to write anything because some messages are printing, like : "ieee80211 phy0: rt2800_wait_wpdma_ready: Error - WPDMA TX/RX busy" "ieee80211 phy0: rt2800pci_set_device_state: Error - Device failed to enter state 4"

Then I notice that my Wi-Fi is also not working....Wait a second my Wi-Fi has stared working - i don't know how. But earlier the output for 'nm-tool' was showing state-unavailable and 'rfkill list" was showing both soft blocked and hard blocked as 'no'. Please help.

My issue has been fixed. Putting this answer here for visitors from the future.

To remove Ubuntu Kylin. I did following :

  • Remove everything kylin

    sudo apt-get purge ubuntukylin-theme ubuntukylin*

  • Change the default plymouth in alternatives

    sudo update-alternatives --config default.plymouth

  • To fix theme and icon pack

    sudo update-initramfs -u

  • Remove grub background

    sudo update-grub

  • In software center remove things that are related to Kylin from your system.

To fix touch pad:

Upon checking in the software updates I noticed that upon updating most of my software resources have been disabled. So, I enabled them. Then did following:

  • Search for 'Synaptic' in the software center
  • Click "show technical items" in the bottom
  • Install everything that is related to touchpad, input or trusty (i.e. your Ubuntu version name)

Hope that helps you dear visitor.
