DVD Playback issues in 14.04 LTS

Well I came across a problem in my upgrade from 12.04 to 14.04 in that DVD's wouldn't play. I did all the usuals with reinstalling unrestricted extras, Libdvdread4, libdvdcss2, ran and none of it worked.

Someone suggest I head over to the #xubuntu channel on IRC. It turns out 12.04 was using /dev/dvd1 for the DVD drive and none of the media players were recognising this. In version 14.04 the DVD drive is now at /dev/sr0. In VLC it is only a matter of changing this in the preferences. Tools > Preferences > Input/Codecs.

Some other media players don't allow you to change the location so the partial solution is to put a systemlink fron /dev/dvd1 to /dev/sr0

Open up terminal and type:

sudo ln -s /dev/sr0 /dev/dvd

Flash support removed from Chromium

Flash content on Chrimium has stopped working in April 2014.

The reason for this is that Google have dropped support for the ‘Netscape Plugin API’ (NPAPI) – used by Adobe Flash – on Linux builds of Chromium. This ageing plugin allows for unrestricted access to a computer and is considered inefficient and insecure, with Google calling it ‘the leading cause of hangs, crashes, and security incidents’.

To install the new Pepper Flash plugin (which now comes with Chrome) open terminal and type.

sudo apt-get install pepperflashplugin-nonfree
sudo update-pepperflashplugin-nonfree --install

Restart Chromium and Flash will now be working.

Dropbox Requires Authentication

I recently upgraded from Xubuntu 12.04 LTS to 14.04 LTS. Everytime I logged on I got the following pop up box requiring my root password.

It would appear that the directory path in the dropbox file was showing the incorrect path:

PARENT_DIR = os.path.expanduser("/var/lib/dropbox") 
DROPBOXD_PATH = "%s/.dropbox-dist/dropboxd" % PARENT_DIR

I tried editing the file as per some online suggestions but this didn't work. However the following worked fine for me. Open Terminal and type:

sudo rm -rf /var/lib/dropbox/.dropbox-dist
dropbox start -i

This removes dropbox from your system and re-installs it.
