I was able to see this flicker issue on the BIOS video-adjustment screen…  
which tells me that it’s a hardware or inherent software issue with the laptop 
itself, not Debian!  The unit is on its way back to Dell now.

Should have tried this first!!

Re: Iceweasel security updates?

The Firefox development process follows a type of cascading release:
http://www.askvg.com/mozilla-updates-firefox-update-channels-nightly-aurora-beta-and-release/

There are nightly builds, which are compiled every night from the public
source tree (assuming it actually builds at the moment), and made
available for developer use. These are bleeding-edge, potentially
unstable and buggy code.

There's the 'Aurora' release channel, which is the next stage of
stability after nightly builds. It's more or less the "experimental
release" niche, the first step towards designating something as a
release; think of it as comparable to an alpha release. After the old
'Aurora' becomes the new 'Beta', a version of the latest nightly code
becomes the new Aurora. Not every new patch gets into Aurora - only
patches which the developers agree are important for the coming release.

There's the 'Beta' release channel, which is the next stage of stability
after Aurora. After the old 'Beta' becomes the new 'Release' version,
the old Aurora becomes the new Beta. As with Aurora, not every new patch
gets into Beta - and the standards for what qualifies to get in are
tighter than with Aurora.

There's the 'Release' release channel, which is what gets published as a
new official Firefox version. Once every six weeks (or thereabouts), the
old Beta becomes the new Release. No patches at all are accepted into
Release, unless a critically urgent oh-shit-that's-bad issue is
discovered and the developers decide to make a "chemspill" point release
(e.g., the difference between 45.0 and 45.0.1).

There's the 'ESR' release channel, which is maintained over roughly a
year-long period. Once every seven Firefox major versions (which come
once every six weeks), a copy of the new Release version becomes the new
ESR. In theory, only security and stability patches make it into the
ESR; new features, and anything which might introduce a regression, are
verboten. (In practice, the developers sometimes don't live up to that
ideal.)


The more you need stability, the lower down this list you should go
with. The newer and faster you need new features and potential bug fixes
(at the risk of new bugs being _added_), the higher up the list you
should go with.

For myself, I always recommend that anyone not actively developing
Firefox should run the ESR.




Thanks for all the details, W!  This should definitely come in handy.

Hi all,

First, I'm asking for help on this list because I've observed this to
be a very august group :) and I'm actually a bit in awe to be in the
presence of Debian developers...  I've only been using Debian for a
few weeks -- I'm not new to Linux or Unix, although I'm still a
relative beginner.

Here's my problem -- when I stream certain videos on Youtube, I
consistently get choppy playback performance, whereby the video
freezes and restarts randomly, with the audio getting out of sync
from that point forward.  The problem is NOT due to the video still
being downloaded -- I know this because the progress bar shows that
the download is way ahead of my viewing progress.

Here are my specs:

- Debian Jessie 32-bit (I had installed 8.3 and subsequently ran some
updates, but I don't know how to check to see if I'm up to 8.4)
- Gnome 3
- Firefox 45.0.1
- Flash is NOT installed
- flashplugin-nonfree is NOT installed
- neither gnash nor pepper are installed
- example of a video that gets choppy:
https://www.youtube.com/watch?v=R6Tok9KUjTw (the problem seems to
start during the "man on the street" segments)
- When the choppiness is happening, System Monitor tells me that one
of my four CPUs is maxing out at 100% at least half the time

Hardware:
​- Dell Inspiron 15 3000 Series (Intel(R)) - 3551
- Intel Pentium CPU N3540 @ 2.16GHz x 4 (2M Cache, up to 2.66 GHz)
- 4GB Single Channel DDR3L 1600MHz (4GBx1)
- Graphics: Intel Bay Trail x86/MMX/SSE2

I would love to receive help from this list...  thanks much much in
advance!

Why did you install the 32-bit version?  You have a 64-bit system,
right?

A few months ago, I installed Jessie 32-bit LXDE desktop in VirtualBox
on a 64-bit host (Wheezy 64-bit) to test video streaming from different
sources. Videos ran awful like what you describe.  I reinstalled, but
the 64-bit version.  Videos streamed perfectly.  Everything else
remained the same.  I just let the installer do its thing.

Why GNOME3?  Could be it's the problem.  I've never been able to try it
on my systems.  It won't run.  My plain vanilla graphics cards just
don't have support for it. I get the "fallback" desktop. Also, GNOME3
has become a bloated resource hog, IMHO.

So, first try the 64-bit version with GANOME3, and if that doesn't
solve the problem look to a lightweight desktop like LXDE or XFCE, or
just a window manager.

And, of course, check you've got the latest video driver installed.

B



Thanks to all of you who helped with this problem -- here are the 
results of my tests, if you're interested:


- I installed the 64-bit Jessie 8.4 with Gnome 3, but I still had the 
problem.

- I then tried LXDE and Xfce, but I experienced the same problem on both.
- I've noticed that the problem does not occur using Iceweasel 38 that 
ships with Jessie -- the problem only occurs in Firefox 45.  I also 
tried unchecking Hardware Acceleration in Firefox, but that did not help.
- I decided to go with Cinnamon, as I like it the best (I definitely got 
in a nice test of the various desktops during this investigation!) and 
it makes life with my particular trackpad the easiest -- all the other 
desktops were too quirky regarding natural scrolling.


Thanks again!

Unfortunately this didn't help -- the problem is still there in 
Firefox.  What's also interesting is that I observed in System Monitor 
that, with Chromium, the usage of my four CPUs is evidently much more 
balanced than with Firefox -- with Chromium, the line graph showing the 
four lines looks like a bunch of wires tightly wrapped together...

Very interesting -- the problem does NOT occur on Chromium!  I have the

8.4) and all videos I tried run perfectly...  I also notice that the 
browser performance overall is snappier than Firefox, so it looks like 
I'll stick with Chromium -- although as another poster suggested that 
moving from the 32 bit version of Jessie to 64 could make my video 
performance better (as well as a possible switch from Gnome 3 to LXDE or 
Xfce) I may decide to make these changes as well.


I didn't address your other questions, Sven, because this seems pretty

The reason why I went with Gnome3 is that I thought I may pursue Android

went with it.  Sure it's a disorienting way of working with your system

as I'm not sure about app development anyway, I don't mind going with 
LXDE or Xfce.


I don't know how to determine whether I've got the "latest video

Do you have your Intel video driver installed?? Video played back here 
just fine using HTML5. Ric


Okay, it looks like I was able to figure out how to detect my video 
driver, using the following command:​

lspci -nnk | grep -i vga -A3

my output is:
​
00:02.0 VGA compatible controller [0300]: Intel Corporation Atom 
Processor Z36xxx/Z37xxx Series Graphics & Display [8086:0f31] (rev 0e)

Subsystem: Dell Device [1028:06ab]
Kernel driver in use: i915
00:13.0 SATA controller [0106]: Intel Corporation Device [8086:0f23] 
(rev 0e)


I hope this helps... thanks in advance gang!

Choppy video on Youtube

[Harris Paltrowitz]

Hi all,

First, I'm asking for help on this list because I've observed this to be 
a very august group :) and I'm actually a bit in awe to be in the 
presence of Debian developers...  I've only been using Debian for a few 
weeks -- I'm not new to Linux or Unix, although I'm still a relative 
beginner.


Here's my problem -- when I stream certain videos on Youtube, I 
consistently get choppy playback performance, whereby the video freezes 
and restarts randomly, with the audio getting out of sync from that 
point forward.  The problem is NOT due to the video still being 
downloaded -- I know this because the progress bar shows that the 
download is way ahead of my viewing progress.


Here are my specs:

- Debian Jessie 32-bit (I had installed 8.3 and subsequently ran some 
updates, but I don't know how to check to see if I'm up to 8.4)

- Gnome 3
- Firefox 45.0.1
- Flash is NOT installed
- flashplugin-nonfree is NOT installed
- neither gnash nor pepper are installed
- example of a video that gets choppy: 
https://www.youtube.com/watch?v=R6Tok9KUjTw (the problem seems to start 
during the "man on the street" segments)
- When the choppiness is happening, System Monitor tells me that one of 
my four CPUs is maxing out at 100% at least half the time


Hardware:
​- Dell Inspiron 15 3000 Series (Intel(R)) - 3551
- Intel Pentium CPU N3540 @ 2.16GHz x 4 (2M Cache, up to 2.66 GHz)
- 4GB Single Channel DDR3L 1600MHz (4GBx1)
- Graphics: Intel Bay Trail x86/MMX/SSE2

I would love to receive help from this list...  thanks much much in advance!

Then, for those cases where html5 is not yet available, UNinstall
flashplayer-nonfree. Adobe has stopped Linux support for it, so it's too
old for those cases that require a newer version.

Hi,

So if Adobe is no longer supporting Flash for Linux, do you think there might 
be security risks to using the flashplayer-nonfree package?
