Linux for beginners

Hi,

So I've got a Dual Boot of Win10 + Kubuntu on my desktop PC. For some reason I can't get any sound while in Kubuntu while using Brave browser but it works fine in Firefox. Is there something I've missed?

Thanks.

 

Silly question; how to install Waterfox in Mint?
Saw the one or two links on google, did not work at least for a beginner.

I wonder if Kubuntu isn't supported.

 

I guess you tried this?

Working fine on Kubuntu 18.04.

 

Thanks.

Then it is probably hardware related. I just tried a live UFD of Solus Plasma and installed Brave = no audio. There's a music player on Solus called Elisa and I couldn't get any sound from it either, but as with the install of Kubuntu, Firefox audio worked fine.

 

VLC wouldn't work in Kubuntu for me either. It just wouldn't play a DVD, it just kept spinning. The drive works fine with VLC playing DVDs in Windows.

 

Maybe it was compiled with other PulseAudio version.

 

I'm not sure what that means or what I can do about it but when I had Kubuntu on this laptop the audio worked in Brave.

 

In Kubuntu, did you install libdvd?
In terminal (Konsole):

Code:

sudo apt install libdvd-pkg && sudo dpkg-reconfigure libdvd-pkg

No I didn't but I will look into it later when I have more time.

Thanks.

 

I just checked on this Mint machine and "Celluloid" plays DVDs without any intervention.

 

That is correct.
Linux Mint comes pre-installed with libdvdcss. (K)ubuntu does not come with libdvdcss pre-installed.
Linux Mint plays DVDs encrypted with CSS 'out of the box', (K)ubuntu first needs libdvdcss to be installed to be able to play DVDs encrypted with CSS.
See:
https://en.wikipedia.org/wiki/Libdvdcss#Distribution
And for installing libdvdcss, again, see:
https://help.ubuntu.com/community/RestrictedFormats/PlayingDVDs#Ubuntu_15.10_and_newer

Code:

sudo apt install libdvd-pkg && sudo dpkg-reconfigure libdvd-pkg

 

I understand. I'm in Kubuntu now and have run that command.

 

That worked! Thank you so much, @Stupendous Man .

 

Now I've just got to find out why Brave browser has no audio. VLC audio works as expected.

 

Great! And you're most welcome.
Now only to see if Disney/Pixar DVDs play correctly. Disney/Pixar DVDs have a particularly difficult protection. In my experience, on Windows, Disney/Pixar DVDs played correctly only in MPC-BE, MPC-HC and Windows Media Player, not in VLC media player (I never tried Pot Player). Only on Kubuntu for about a month, I haven't tested any Disney/Pixar DVDs, yet. However, as I read, not automatically playing the DVD, but using the DVDs own menu to start the movie, may do the trick. But this has nothing to do with Linux, only with Disney/Pixar DVD protection.

 

Just curious. In a dual-boot setup with Windows will a resident AV scan the Linux partition/s?

 

Provided filesystems on these partitions are mounted then yes, but Windows doesn't support them without third party drivers.

 

So booting into Windows doesn't mount the Linux partitions though, right?

 

@Krusty,

On Kubuntu, there's another thing you may encounter:
If you use K3b to try to burn some CD-R, you may get this error: "cdrecord has no permission to open the device".
To fix that, in terminal (Konsole):

Code:

sudo chmod 4711 /usr/bin/wodim
sudo chmod 4711 /usr/bin/cdrdao

Thanks again. I've booted into Windows at the moment but will run those next time I'm back in Kubuntu.

 

@Krusty,

Another Kubuntu 18.04 thing you may notice some time, is that Dolphin file manager does not allow to be launched as root.
That may be an issue if some directory that should be user's, instead has root permissions only. This can be the case when a directory was modified or created by partition manager, and also Clonezilla images save with root ownership, I noticed. If you need to handle such root ownership directories, or perhaps like to change ownership to user's, Kubuntu 18.04 Dolphin file manager does not allow that.
Some options to handle this issue were mentioned by Igor Ljubuncic, in this article:
https://www.dedoimedo.com/computers/kde-dolphin-as-root.html
I chose another option. I chose to install Krusader file manager. Krusader offers root mode (Tools/ Start Root Mode Krusader). In cases as I mentioned, I start Krusader's root mode, and make the modifications that I need. For normal use, I use Dolpin.

 

I think it is good thing root access is limited to command line commands. It is just to easy to break things in GUI with root privileges.

 

Something that I find a little odd is that in Kubuntu the dark theme doesn't extend into the Options / Preferences page nor the Add-ons page. On all other Operating Systems it does. Can this be changed on Kubuntu?
