Have just installed LL on an older laptop via the DVD drive. No problem with the installation and the laptop is now at least as fast as my main machine, thanks for that.  Have checked the BIAS boot sequence and Sony DVD-RW DW-Q520A is shown, but it is not recognised by LL. I'm not conversant with LL and much internet searching has not provided any info on how to get the DVD drive mounted in LL. I would be grateful if you could point me in the right direction. Many thanks

What do you mean by mounted ?

Normally an optical drive doesn't show in a linux file-manager until it has a cd or dvd inserted into it.
It should then show and offer to open the appropriate program to view the contents, whether they be music, film or data.

Hi - Thanks for the response. The Sony DVD drive is not shown under drives and inserting a film/music DVD has no effect, but the drive is OK as I can insert the installation disc and run it on the laptop. At one time I did get a message 'Can't mount file' relating to the DVD drive, which is why I mentioned the term 'mounted'. Apologies for not being more specific, I'm feeling my way with LL. - Regards

@dapeba Ubuntu Bionic 18.04 which Linux Lite is based on won't play dvd's out of the box so extra software is needed,

In a terminal enter these 3 commands  one at a time:

Code: [Select]
sudo apt update

Enter your password, then

Code: [Select]
sudo apt install libdvdnav4 libdvdread4 gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly libdvd-pkg
Code: [Select]
sudo apt install ubuntu-restricted-extras
source: https://websiteforstudents.com/enable-dvd-and-copy-right-videos-support-on-ubuntu-18-04-lts-beta/

Reboot and you should be good to go.
Hope this helps :)

This is what I was looking for. It is the knowledge that I have always wanted to study.

Hi - Many thanks for your help. I carried out the steps you recommended, after I had discovered that typing your password in terminal doesn't show on the screen. The position is still the same, even with a dvd in situ the drive is not shown in drives. I connected an xtnl HD and this did show in drives, although attempting to play a dvd resulted in a system lock and I had to force release. Is the problem that there isn't a LL driver for this particular dvd drive? I have checked on line and there are drivers for it but they only seem to be for Windows, would they be of any use? Another thought, is it possible that there might have been a glitch in the installation, and would a uninstall and reinstall be advisable? - Regards

@dapeba  You could try Menu/Settings/Install Drivers and see if any proprietry drivers are needed or available.

Open a Terminal, do:

Code: [Select]
dmesg | egrep -i --color 'cdrom|dvd|cd/rw|writer'
and show us the output. Make sure your external drive IS NOT plugged in Let's start there.

Thanks for the reply, and apologies for being away from the workface for a while. Must also apologise for lack of LL knowledge. And this is possibly why I get the result below. The command prompt reverts back to the command line, and I tried this a few times.

Hi - Trying to play a DVD produces this message. New to LL but in Windows it would mean an unrecognised device, that would indicate a driver problem.

Playback failure:
DVDRead could not open the disc "/dev/sr0".
Your input can't be opened:
VLC is unable to open the MRL 'dvd:///dev/sr0'. Check the log for details.

Regards

Hi Jerry - Connected the Xtnl HD that I used to use with this laptop. VLC happily played .WAV files but locked the system when attempting to play a .mp4 video file. I mention this in case it throws some light on the problem. - Regards, D
