Transcripts
hey everyone this is Nick and welcome to
this week's edition of the Linux and
open source news show and this week we
have Nvidia making their open-source
kernel modules the way forward for their
recent gpus instead of the proprietary
drivers we also have a new attack that
makes all vpns basically useless and it
does affect Linux Mac OS Windows the
only OS that isn't affected is Android
apparently and we also have some more
news about Cosmic we have valve
contributing to the nvk drivers and a
lot more including this segue to our
sponsor this video is sponsored by
proton mail they make a suite of online
tools focused on privacy with end and
zero access encrypted email an online
storage space a calendar a VPN and a
password manager the goal is to offer an
all-in-one Suite of services that
respect your privacy and give you the
tools to avoid being tracked in your
inbox and buy the tools you use every
day to get work done and if you're
wondering why that's so important here
is a perfect example if you use Outlook
you might have seen this screen pop up
informing you that from now on Microsoft
will use and share your data with
801 different partners and with that
data they can precisely locate you
identify you through fingerprinting and
they can display ads straight inside ins
your inbox looking like regular email if
you use the new Outlook email app with
other email Services than Outlook you
will also Grant access to all of your
data to Microsoft including the ability
to read your emails and this will all be
stored in their Cloud you can create a
free proton account by clicking the link
in the description below and if you ever
need more Advance features or more
storage space they have paid plans you
can use to I use Pro on mail and I can
definitely recommended so the link is
down there so let's talk about Nvidia
and their drivers and it looks like
Nvidia is moving towards making their
open-source modules the default for
recent gpus so for RTX 2000 series gpus
and up in the Nvidia 560 driver series
which is not released yet they're
planning to use their open-source cural
modules instead of the proprietary
driver that's not nvo that's not nvk
it's the open source driver Nvidia
develops themselves and that isn't part
of the Linux kernel meaning you will
still have to install an additional
package or you'll have to run a do run
installed file from nvidia's website or
alternatively this Ros will have to
package these modules and decide whether
they want to ship them as part of their
default install which shouldn't be that
problematic anymore because well they're
open source you will still be able to
pick the proprietor driver instead but
Nvidia said that in the future chances
are some gpus will only be supported by
their open source modules now before you
get excited do note that this is only
for the kernel drivers the user space
drivers that handle openg GL or Vulcan
or Cuda these are still closed Source
here as is the generic firmware for
these gpus still it is good progress and
with Nvidia developers contributing to
Novo and nvk it's not entirely
unreasonable to think that at some point
on top of these open source kernel
modules from Nvidia you might be able to
just run nvk and have that full
opensource stack which would be really
cool we have more news about the cosmic
desktop their developers have now almost
finished implementing display mirroring
which apparently also supports cases
where the resolution the orientation or
the refresh rates are different between
your displays system 76 is also building
arm 64 variants of their packages and
their brand new app store is now
completed apart from some minor ux
issues although it just looks like any
other app store it's apparently really
fast though they say they found it more
efficient than using the command line
the file manager gained integration with
gnome's virtual file system to handle
all the external file storage the login
manager is now done as well and they've
also created a new widget in their lib
Cosmic library to let developers
Implement context menus some fixes were
applied to theming as well and a bunch
of other issues were dealt with with the
compositor with the screenshot tool with
scrolling and other things and Cosmic is
also getting some attention from the
community even though it's not out yet
with a new GitHub template being created
to Kickstart the creation of cosmic apps
and a new web app manager being created
as well and in the process of being
added to flath hop an input sources
Outlet was also created to change
keyboard layouts and settings from the
top panel of cosmic so I do hope the
alpha is still planned for the end of
this month I booked a video slot to demo
what they've accomplished I'm not
expecting it to be as full featured as
KD or not even as gnome especially in
terms of the default applications but it
does look like they have covered all the
basics and it will be interesting to
look at a new desktop environment built
from scratch with the modern Linux tack
in mind instead of carrying around a lot
of old Legacy code for X11 and stuff
that's been here for like decades by now
now there's a new attack that renders
most vpns completely useless and when I
say new I mean it has been found by
researchers recently but it potentially
could have existed and been used since
2002 the new method called tunnel vision
lets an attacker read drop or modify any
traffic that tries to go through a VPN
all the while maintaining that
connection to the VPN and to the
internet meaning you wouldn't even know
that it's happening it works by running
a DHCP server in Gateway mode on the
same network as the VPN user and then by
using traffic forwarding rules to pass
that traffic to a real Gateway spying
everything that goes through the DHCP
server in the meantime these routes are
never encrypted through the VPN in that
process this attack works on any OS
apart from Android apparently because it
doesn't implement the option which is
what is being used in the attacker DHCP
server on Linux you can minimize the
effects of the attack but not entirely
prevented and other operating systems
are completely affected the attacker
still needs to have admin privileges
over your network like for example
having access to the admin interface of
your router which isn't too hard at
least in France because most of the ISP
routers are just using admin as a login
and a password untrusted public networks
could also be very easily targeted and
this is where you would be most likely
to use a VPN so you would connect to a
very basic hotel or airport or cafe
Wi-Fi you would turn on your VPN and
feel like everything is safe and secure
but it wouldn't be and you wouldn't even
be able to know someone somewhere has a
DHCP server that is getting all your
traffic and then passing it back to a
regular server that then passes it to
the VPN and everything looks encrypted
it's a man in the- Middle attack
basically now open source is really cool
because everyone can contribute but
sometimes it also means we reach Peak
stupidity because some Pokémon go
players are apparently modifying real
open street map data to add beaches
where these don't exist in real life
because this will never them increase
chances of catching some rare Pokemon in
their game now since Pokémon go uses
real map data from osm to make their
virtual creatures available in their app
and to pinpoint certain points of
interest that let you refill your Poke
Balls and stuff like that some players
just thought it would be acceptable to
just change the real map the worst thing
is that Pokemon go might not even update
their open street map data regularly or
at all meaning that first these
modifications aren't even guaranteed to
help people catch these Pokémon in their
game and second they're actually
modifying real mapping data something
that is used by actual useful
applications and programs all across the
world sometimes the Griefers even draw
their own pseudonym on the map and it
also seems that some anti- pookemon go
people are now removing real points of
interest just because they are used in
game to give certain game advantages to
Pokémon go players obviously do not
change real map data just to fit a game
that might not even pull that data for 5
months it's stupid this is real data
that has been contributed over the years
by a dedicated Community do not do that
but also apparently since Pokémon go
moved to osm in 2017 I think a lot of
people started implementing more data
into osm because they want their CD to
have the points of interest that could
be used in game and so the quality of
the data in osm has improved thanks to
an influx of Pokémon go contributors
which I mean that's okay doesn't give
you the excuse to actually destroy the
real map though now it looks like valve
is taking an interest in the nvk open
source Vulcan drivers for NVIDIA they've
been working on bringing explicit sync
to these drivers this is a feature that
is needed to get better performance less
latency and less graphical glitches on
Nvidia it's something that both gnome
and KY are working on as well to make
sure that they can support it once the
drivers actually have that feature so
now thanks to valve the nvk driver will
support that and the gamec scope
compositor that valve users in Steam OS
will also be able to make use of that
the newvo kernel driver also received
updates to support the feature so it
will definitely make nvk a more viable
option in the near future but what is
really interesting here is that it's
valve contributing to an Nvidia driver
because valve generally just uses AMD
stuff their steam deck and Steam OS is
for now only rated to run on an AMD Apu
so them contributing to some Nvidia code
might mean they're getting ready to
either open up steam o to more computers
or to maybe start onboarding partners
that might want to ship Nvidia gpus in
their devices that could run Steam OS we
not there yet but them contributing to
Nvidia only stuff it's cool maybe they
were just waiting for an open- Source
driver to not have any licensing
problems and legal issues by having to
ship an Nvidia proprietary driver and
let's finish this with the gaming news
first we have Ste o 3.6 it's now in
preview and it updates the entire Arch
base of the distribution with the kernel
6.5 the latest Mesa 24.1 and so
basically improved performance overall
in terms of Steam OS specific features
they apparently improved how the display
looks on the steam Deck with better
colar balance and better gamma
uniformity the steam UI should also be
more responsive which is an issue I've
had on my steam deck where things are
not stuttery but they're not that smooth
either but the desktop mode of Steam OS
is still stuck to KD 5.27 it doesn't get
plasma 6 for now the BIOS was also
updated for the steam deck bringing
overclocking controls to the steam deck
LCD there are a bunch of other
interesting changes as well first
pairing with airpods is improved you can
now wake the device using a controller
meaning it should now behave like a
proper console where you can turn on the
controller and start playing instead of
having to turn on the device manually
and the steam deck doc also supports TV
remote input TV wake up and TV input
switching over HDMI so technically you
could you just put your steam deck to
sleep in its deck dock you turn off your
TV and when you turn on the controller
it wakes up the steam deck it wakes up
the TV and it works just like any gaming
console which is cool I'll make sure to
give that preview a shot just to see how
well it works and if it does work maybe
I'll try using Steam OS or Holo ISO
again on my steam gaming console because
that was an issue I had where I just had
to get off my lazy ass and turn on the
thing with the button it wasn't in a
convenient location it just wasn't
practical turning it on with a
controller much better and we also have
a few more details about platron OS the
linux-based gaming OS that the platron
company wants to bring to a few
handhelds and other devices they have
big plans for this they want to push it
to TVs to PCS to handhelds and more and
they actually received some sizable
investment so now we know that the OS
will let you play games from Steam epic
games Gog and more and they say it has
improved game game compatibility
compared to other systems I guess
because it will let you use things like
the heroic launcher or another
implementation of the legendary API to
connect to the epic game store more
easily than on Steam OS they said the
pre-launch will be in 2024 and many
devices are planned for 2025 although
only one has been announced for now
platron OS is apparently based on Fedora
silver blue 40 and they also said they
tested things on the steam deck the the
Lenovo Legion go the GPD win for or the
Rog allies they also said that they were
backed by a handful of crypto companies
which is never a good sign for any
product and they also said that only the
core OS code would be open source so
probably their entire gaming interface
and compatibility with other launchers
will not be open source although that's
also not the case with Steam OS the the
interface and the steam client are not
open source either so I don't think
that's such a giant issue I'm always up
for these kinds of projects that try to
push Linux based systems to mass Market
or at least consumer-based devices but
the crypto stuff always smells fishy and
until they've actually shown the system
running on some actual hardware and
until they announce some Partnerships
some real physical stuff I will treat it
as vaporware what isn't vaporware though
is our sponsor tuxedo computers they
make computers that are definitely real
and that ship with Linux pre-installed
you can buy them using the link in the
description below they have a big range
of devices from small Ultra books for
office work all the way up to gaming
laptops giant workstations giant gaming
towers and everything in between all
their computers are very customizable
you can open the laptops you can repair
them and upgrade them you can have your
own custom keyboard layout they are
really really good and you're guaranteed
to have really good Linux support
because that's what they do they make
computers with Linux I only use tuxedo
computerss these days my entire Channel
runs on one of their laptops and all my
gaming needs are served by one of their
desktop so if you want to check them out
the link is in the description below I
can only recommend them so thanks
everyone for watching the video I hope
you enjoyed it if you did all the usual
YouTube buttons are down there like
comment subscribe notifications whatever
you know how things work and if you
really like the channel there are links
in the description to support it
financially if you become a patreon
member or YouTube member you will get
access to a daily version of this show
so thanks for watching and I guess
you'll see me in the next one bye
