Re: [PLUG] VLC 3.0

[Jason Barnett]

I can vouch for Kubuntu 18.04 (upgraded from 17.10, Xorg) that the included
VLC 3.0.1 does NOT have any issues with the screensaver.
Not sure if this information is of any use to you, but now you know.

While I might not know what is Compiz, I certainly can recognize familiar
smell of major trouble coming - when I hear about upgrading U-buntu for the
last 12 releases AND not practicing regular clean installs.

Just a word of caution,

What you said is possible.

I have three computers:
1.  desktop built 2 mos ago, started with Xubuntu 17.10 and just
upgraded to 18.04. 
2.  Lenovo T61 laptop, had 12.04 when it was retired; recently
revived and dist-upgraded to 14.04 > 16.04 > 18.04
3.  System76 laptop, still running Xubuntu 14.04.5. Has VLC 2.2.5
which inhibits the screensaver as it should.

Both 1 and 2 have VLC 3.0.1 (from the dist-upgrades), which fails to
inhibit the screensaver. 

I wonder what pieces of Wayland are still on 1 and 2, and what kind of
exorcism is needed to get rid of them.

While VLC 3.0.1 is the current version in the 18.04 repositories,
version 3.0.2 has been released. I've looked everywhere for a change-log
to see if it addresses this issue, but can't find one.

Re: [PLUG] VLC 3.0

What did you dist upgrade from? If it was Ubuntu 17.10 you are probably
running Wayland, which is most likely the problem. They reverted back to
Xorg with 18.04, but if you upgraded from 17.10 it may have carried Wayland
as the default from that. Wayland breaks many things, not the least of
which is the screensaver API.

Very interesting observations.

Re turning off compiz on Ubuntu. I have a GUI called Settings Manager
which allows me to call up additional windows for specific settings.
One of them is called Window Manager Tweaks, and its window has tabs
for various functions, one of which is labeled Compositor. At the top
of the Compositor options tab is a button to turn it off. I just did so
on my desktop (18.04) and the shadows under windows immediately
disappeared. But note that all my computers have Xubuntu and have never
had any other DE - no Gnome, Unity, Mate, etc. ad nauseam. So maybe
that I can turn it off is a function of Xfce rather than Ubuntu.

Having said that, I am going to leave it turned off just to see if it
affects the fact that VLC's option to disable the screensaver is
broken. It probably won't make any difference, but what the heck.

You just hit the spot at the right pre-school level Ben,

This I understand perfectly - it is a yoke intended to make everything
looking cool - an it is firmly stuck between the desktop environment
and the screen.

Thanks, I get it now, it should not add to my Linux experience in any

Re: [PLUG] VLC 3.0

[Ben Koenig]

Compiz makes your desktop look cool.

Compiz can break certain applications.

As an analogy, if we compare VLC to a website... then Compiz is a module 
you enable in the web server to add graphical effects to VLC.


Now imagine if this web server module that you enable in http.conf was 
integrated into the webserver, and impossible to disable.
That is what ubuntu did with compiz. They included the graphical effects 
system at a level that can't be turned off. This results in applications 
such as VLC encountering problems that go back 10 years, because control 
over how the video is rendered to the screen has been taken away from 
the video player.


I hope that clarifies it. This is a topic worth keeping tabs on because 
it directly affects how server-side data is presented to the user on the 
client side.

Compiz is a window manager that enables desktop effects similar to
those
found in Mac OS X and Windows Aero. It accomplishes this by drawing
application windows to the screen using OpenGL and you graphics card.
It
is a component of your Desktop Environment.

Maximize, minimize, and window manipulation that we expect on a
desktop
computer is handed by a "Window Manager". Compiz provides these
features
using opengl on your GPU, so it can go nuts and arrange your desktop
in
3 dimensions. Windows Aero MacOS Expo/Mission Control...  or in
our
case the Compiz Desktop Cube.


Most DE's such as KDE and whatnot have the ability to run a
different
WM, therefore drastically changing the way windows are managed.

Compiz allows the user to add a bit of art to their desktop by
altering
the appearance of windows and objects. As a common example that I
use
myself, you can add a shadow around windows. I keep my shadow
thin and
not very dark so it is just a hint. If you're not artistically
inclined, then compiz is not for you.

Sorry, that was more than one sentence. Hopefully they were
digestible.
