Subject: I am thinking of buying Raspberry Pi 4 Model B 8GB with 7 or
10 inch touch screen display in June 2021
Good day from Singapore,
I am thinking of buying Raspberry Pi 4 Model B 8GB with 7 or 10 inch
touch screen display in June 2021.
Raspberry Pi 4 Model B - 8GB (Latest) - Price SGD$120
Raspberry Pi 7 Inch Touch Screen Display With SmartiPi Case - Price SGD$147
Do you think it is a good match?
I want to use my Raspberry Pi like a regular laptop or desktop
computer. Would a 7 inch touch screen display be too small for my use
case? I don't want to strain my eyes looking at a small display.
However, if I get a 10 inch touch screen display, I can't find one
with a supporting base. I can't find a 10 inch touch screen display
with a supporting base which could allow the screen to stand
Finally, does your Linux distribution support Raspberry Pi 4 Model B 8
GB? Can I do 4K Ultra HD video editing on the Raspberry Pi 4 Model B 8
GB? Like adding watermarks, and cutting away unwanted 4K scenes. Is
there a good 4K video editing software for Linux?
I am looking forward to your reply.
Thank you very much.

I just got me a new laptop, so now I need to limit my screen resolution.
...the new laptop has a 14" 4K display, I really don't need 3840x2160 on that
little screen - FullHD should be more than enough, expecially when that means
better performance in games.
I know I can switch the resolution on a per user basis in Plasma or Gnome, but
how can I limit the whole thing to "only" 1920x1080? As in, even gdm/sddm runs
at that resolution?
Back in the olden days I'd put that in /etc/X11/xorg.conf or somewhere like
that, but nowadays that file doesn't exist and everything's autodetected...

Hi, I installed K3b on my 32 bit and 64 bit (TDE) computers and decided
to test how the application performed.
Settings > Configure K3b > Devices > Displays the following error:
In order to give K3b full access to the writer device the current user
needs be added to a group cdrom.
The Permission helper that could do this for you was not enabled during
Please rebuild the package with the Permission helper enabled or contact
K3b was able on both machines (32 and 64 bit TDE) to complete the
burning of an .iso and verify without incident.
I attached a screenshot of the error message here. >
1. How can I enable this permission helper that is spoke of?
2. How should I go about adding a cdrom group? I am not seeing the
capability in (YaST > Control Center > Security and Users > User and
Group Management >) most likely I am missing something about how to use
this particular module.
3. Do I need to uninstall K3b and reinstall again (once a group cdrom is
4. Will removing K3b and the dependencies of K3b through YaST Software
Manager create potential dependency problems?
5. I was looking at this YaST CD-ROM Drives module page: >
Most likely I am missing something in the YaST - User and Group
Management section. Is there a preferred openSUSE Wiki Portal on this
topic of adding groups and users through YaST?
I looked at this information briefly and it refers to a CD-ROM Drives
module: > https://en.opensuse.org/YaST_CD-ROM_Drives < Seems to be not
relevant most likely.
What are your thoughts on this matter?
I recently attempted to Hold/Lock a specific kernel in place on openSUSE
TW. My hardware is 32 bit so I am currently inhibited by having to load
a specific kernel-release (a newer release is not allowing the computer
to boot). See the following link if you are interested in more details
on the filed bug report: ->
I edited the following file with Kate text editor /etc/zypp/zypp.conf
scrolled down to line 554 and edited the following entry to:
multiversion.kernels = latest,running,5.11.16-1-pae
" Keep the last two kernels and the one currently running.
multiversion.kernels = latest,running,5.11.16-1-pae "
I saved the edited file and closed Kate. I then opened
/etc/zypp/zypp.conf and verified that in fact the entry I created had
been saved. Then I powercycled the computer (maybe twice I am not
certain-most likely only once). Needless to say that the boot menu has
no more listing for "kernel-5.11.16-1-pae". There were 2 listing's for
kernel-5.12.series (both unbootable).
I have been reviewing the following link concerning this: >
1. I really would like to ask as to if the reason for failing to hold
the "kernel-5.11.16-1-pae" was/is this because of the fact I edited the
zypp.conf file's entry incorrectly by adding the "kernel-flavor" suffix
(5.11.16-1-pae <-Not Entering-> 5.11.16-1) instead?
2. What is the best way to Hold/Lock the running kernel?
3. is YaST2 sometimes used for this task?

I will explain, again, how you do this.
1) Create a directory, for example /home/doug/extrarepository/
2) Copy all the rpms from that commercial thing into that directory.
3) start yast as root in graphic mode:
4) Start the "Software repository" module
5) Click the button "Add repository"
6) on the list that appears, click "Local directory", then [next].
7.0) On "repository name" put whatever you like.
7.1) On path to directory, you write the path (/home/doug/extrarepository/).
7.2) Click on "Plain rpm directory"
It thinks for a while, and if all goes well, you click [OK].
Now, you have created your own private repository for external packages.
Next, install those packages.
1) On YaST, click "Software management module
2) On view, select "repositories".
3.0) On repositories, you will see a list of repositories on the left
panel. Select the repository you created.
3.1) On the right panel, you will see the list of packages in that
repository. If it is empty, exit YaST, run "zypper refresh --force" and
try yast2 again.
3.2) select the package, solve the dependencies if needed, accept and

I would like to compile the above listed package but I am curious as to
if I have done a step incorrectly up to this point. I am also of course
wondering if it would be best to install package libdvdcss2 as well.
I do notice by using VLC that the same dvd medium I previously tried
"Plays the same movie as before with no libdvdcss instance installed".
Switching to a different dvd medium results in no playback at all. The
drive is certainly activated when the VLC media play key is clicked. I
verified with "lsblk" I have the correct block device selected also.
Suggestions on this would be a great help.
I was working with my Compaq nc-6400 laptop yesterday (openSUSE TW) and
I installed the "Packman Essentials" repository also "libdvdcss2" from
the following links I have documented.
Packman Essentials ->
"https://en.opensuse.org/Additional_package_repositories" I am seeing
now that the openSUSE TW portal located here
"https://en.opensuse.org/Portal:Tumbleweed" has maybe a better link for
"Packman Essentials" under the "Multimedia Codecs" section. Than what I
have been using currently.
My main question here is perhaps the following: Is the "libdvdcss2"
repository needed for DVD playback anymore?
I ended up removing the "libdvdcss2" repository (for some reason) then
(I am not sure if it was necessary) Powercycled the laptop. VLC media
player loaded the movie DVD perfectly with no notable problems/issues
How can this be? I made certain and saw with "zypper lr" that there is
absolutely no "libdvdcss2" repository left on the computer. Is it not
necessary anymore for DVD/CD playback? At this time the computer is
unbootable due to a bug in the "5.12.0-1-pae kernel" but ugh I would
like to get your thoughts even if brief on this maybe.
I'm getting ready to upgrade my desktop (TDE) to the newest stable release, using zypper
dup. Should I include --solver-focus=Update or leave it to the --solver-focus=Job
