Re: [arch-general] Announcing pacpak

[pelzflorian (Florian Pelz)]

Hello,

A while ago I started pacman and pacbub for file system isolation of
pacman packages. pacpak and pacbub are dead now. They were the wrong
approach for user space isolation. It all gets too hacky. It’s not KISS.
I don’t like it anymore and would rather use GNU Guix for isolating
users’ applications.

Note that if you want to fine-tune a sandbox for a single application,
bubblewrap is great. However, what I wanted is that I can install the
GNOME packages in one tree and then create other trees out of it, for
example one with gnome-maps and one with gnome-2048, but without
redownloading all files and wasting disk space. Inheriting from another
filesystem tree is what gets ugly because pacman and Arch packages are
not designed for that – it probably works somewhat except for the pacman
database but it’s too hacky.

Guix is still pretty unstable and containerization support (e.g. `guix
environment --container --ad-hoc coreutils`) currently is ugly too
(compared to bubblewrap) but at least its basic design and intended use
seem right for it.

I am sorry for choosing the wrong path with Flatpak+pacman and
bubblewrap+pacman and being slow at that too. It would have been much
more work than I had hoped for and I don’t want to maintain a cluster of
hacks.

Regards,
Florian

A user should get the skills to add an alias with what ever should
please her. It makes sense to avoid similar names. "sctl" is similar to
"sysctl", while "systemctl" follows the style of the system family
"system...". For many computer users typing isn't an issue. It makes
more sense to have plausible default names.

Not about systemd, but about your request. This is the wrong list for
such a request and apart from this, it's the wrong time to ask those
questions. You are years too late with those questions.

[arch-general] Inquiry about research paper

[Jaewon Choi via arch-general]

Dear Arch Linux community,

Hello, my name is Irvin Choi I am student from Dwight School Seoul, and I
am writing a extended essay within IB (ibo.org) curriculum research paper
about systemd, service manager for Linux/GNU operating system. There are
few questions that I would like to ask to broaden my understanding
regarding systemd, and I would like to kindly ask you to answer them to
best of your ability.

It is very important for my research paper, as the research paper plays
huge role in my high school curriculum and possibly my future. I would like
to mention that, I may use your questions on the research paper for
credibility purposes.

Here are the questions (please consider explaining your answers and avoid
short answers):

1) Who are you and what do you do for the community?

2) What do you think of the systemd as a service manager? Do you have an
opinion about its pros and cons?

3) What do you think users of the distribution thinks about the systemd? Do
you think they favor systemd? If not, why so?

4) Through my research, I was able to see that there are existing service
managers such as upstart, sysvinit, and others. Why did systemd become the
standard over the others in most of the distributions? Was it worth the
replacement of existing service manager that is seen to be reliable?

5) What changes that do you think systemd should make to improve itself?
For instance, ‘typing systemctl everytime is bothersome. Systemd should
shorten it to sctl instead.)

6) There are lots of Linux/GNU users across the world. To what users are
systemd intended for? Do you think systemd is useful for the servers
administrators, desktop users, laptop users, or others?

7) I’ve heard that there are lots of debate about systemd and it really got
heated at one point, involving personal opinions, politics, and others.
What was the cause and how did it get resolved (if at all)?

8) Is there anything else you would like to tell me about systemd?

Thank you very much time.. It means a lot for me, as I am really interested
in Linux/GNU system, and this became the opportunity to broaden my
understanding.

Have a great day.

Hi,

it happens also when booting an Ubuntu Mate 16.10 Live DVD.
I'll test my Arch Linux install without xorg.conf.

With my current xorg.conf only 1152x864 provides a vertical frequency

Does the problem persist if you remove your X config so it just runs the
defaults? In my experience Intel generally requires little to no
configuration to work well with X.

Re: [arch-general] Archlinux i3wm i3-scrot copy clipboard

[Ben Oliver via arch-general]

Would this work?

bindsym Print exec scrot 'screenshot.png' -e 'xclip -selection c
-t image/png $f'

(note that this binds it to the print screen key)

[arch-general] Intel graphics issue

[Ralf Mardorf]

Hi,

this is my first Intel graphics and the first time I can't get rid of an
issue. I never experienced such an issue with NVIDIA or ATI graphics.

In the upper left corner of the screen, there's a flashing line,
whenever I use lower resolutions than 1152x864 at 60 Hz.

With my Arch Linux I'm using 1152x864 at 90 Hz and there's no
noticeable flashing line, but for the syslinux menu or e.g. a live media
I need to use different resolutions at 60 Hz.

If I switch from 1152x864 at 90 Hz to 1024x768 at 60 Hz, something I
seldom, but sometimes need to do, a flashing line is visible when
running Arch Linux, too.

I posted this to an Intel forum:

"Hi,

in the upper left corner of the screen, there's a flashing line visible
at the syslinux bootloader menu, as well as when running a Linux window
manager, e.g. openbox on Arch Linux or a Linux desktop environment,
e.g. Ubuntu Mate 16.10.

CPU: INTEL CELERON G1840 BX80646G1840
Mobo: GIGABYTE GA-B85M-D3H
CRT: LIFETEC/MEDION MD1998JB Type J91B

This doesn't happen, when using the same monitor with an ASUS M2A-VM
HDMI mobo and an AMD Athlon BE-2350 CPU.

How can I get rid of this annoying flashing line.

Ralf" - https://communities.intel.com/message/455301#455301
