Ubuntu 14.01 LTS (Trusty Tahr)

After months of clicking the “remind me later” button when prompted to upgrade, I finally too the plunge.
And as I feared, things went wrong 🙁

  • Once the upgrade complete, I was greeted with a grey screen when opening VNC (I do everything “headless”)
    • Even with changes to the vnc startup file, I’d end up with no unity launcher and no task bar
  • The keyboard was messed up:
    • Impossible to type ‘s’
    • Typing ‘d’ minimised everything
    • ‘up’ maximized the window (no access to previous command in the terminal)
  • Apache was not working anymore

Needless to say I was not a happy bunny.

After hours of “googling” (I know there’s no such word), endless changes to vnc config, dconf, and reboot, I finally managed to fix everything:

  • The fix for the grey screen / lack of unity launcher / lack of task bar was settled by changing my ~/.vnc/xstartup with the below:
    • #!/bin/sh
      export XKL_XMODMAP_DISABLE=1
      vncconfig -iconic &
      x-window-manager &
      gnome-panel &
      gnome-settings-daemon &
      metacity &
      nautilus -n &
      gnome-terminal &
      gnome-session -session=ubuntu &
    • This didn’t fully resolve the issue as the look and feel is the old, pre-unity desktop, with top and bottom bars, no side launcher. But at least I can work with that for now.
  • I fixed the keyboard layout with the dconf tool:
    • If not yet installed, type
      sudo apt-get install dconf-tools
    • Then type

      and you should get this:

    • dconf-01Go to desktop > ibus > general and tick the box “use-system-keyboard-layout“:
    • dconf-02Then go to org > gnome > desktop > vm > keybindings and replace any entry with the work “super” with “[]”:
  • dconf-03Websites have a new path under Apache. Whereas it used to be under /var/www/, the default path is now /var/www/html/.
      • Of course as I upgraded, I decided to keep my settings, which pretty much rendered everything useless.
      • I ended up completely removing Apache and reinstalling it with these commands:
      • sudo apt-get update
        sudo apt-get purge apache2
        sudo apt-get install apache2
      • All I had left to do was to more the content of /var/www/ to /var/www/html/

Everything is now working again 🙂
