Latte-dock depends on the window manager's compositor. If you use
Alt-Shift-F12 in Plasma5 to disable compositing (for instance if
you want to record audio and the compositor is just eating your
precious CPU cycles) then you do not want Latte-dock running.

Hopefully I'll get somewhere sometime and have ALSA/Pulse --> JACK working
out of the box.

Using a squashfs module created from nvidia-kernel and nvidia-driver packages.
A sample script for creating this nvidia module was added to liveslak, see:
./contrib/scripts/makemod_nvidia.
These two packages were created using the scripts from slackbuilds.org:
https://slackbuilds.org/repository/14.2/system/nvidia-kernel/
https://slackbuilds.org/repository/14.2/system/nvidia-driver/
Note that the nvidia-driver package was created on a multilib system so that
it could pick up 32bit compat libraries (needed for Steam among others),
and the CURRENT variable was set to 'yes' so that the nvidia drivers are
fully separated from mesa and xorg-server and do not overwrite system libraries:
# COMPAT32="yes" CURRENT="yes" ./nvidia-driver.SlackBuild

By default the UidNumber which is used to create the live account is: 1000.
The variable LIVEUIDNR can be set to another unused value if you want.
Remember, customizations go into 'make_slackware_live.conf'
so that you do not have to edit 'make_slackware_live.sh'.

This was fixed in Slackware as well in the meantime, but it does not harm
to keep it in here.

Nobody used the 1 GB ISO with a stripped KDE4 anyway, so I removed it.
DAW is a 'Work In Progress': I want a Ditigal Audio Workstation as a
Live Slackware OS with Plasma5. I want to learn if Plasma5 is lean and
fast enough for realtime audio processing. Probably it also needs PAM,
which will enter the main distro soon.

Note that the Plasma5 ISO size reduction was achieved by removing
almost all of the 'alien' packages which originate in my regular
package repositories.
Which means if you want a Plasma5 Live with calibre, libreoffice,
qbittorrent, vlc and all the other goodies, you will have to create
a persistent Live USB stick and add my packages as "addon modules".

Since cpio 2.13, this option strips '/' and '../' from symbolic and
hard links during extraction of a cpio archive like our initramfs.
This is implemented as a fix for CVE-2015-1197 but breaks the initrd.
And leaving out this option does not have the adverse effect
I always thought it would have... archive extraction is still done
into the current directory and not in the filesystem root.

The virtio_pci driver is required in some cases when using older
types of virtual machine software.

The '-m' parameter of the 'make_slackware_live.sh' script allows you
to add more packages to the Live ISO without modifying any of the script's
"SEQ_*" package sequence variables.
However, the script would prepend "pkglist:" to the argument value, which
is redundant since 'pkglist' is the default anyway.
By removing this prepend string we can now allow a syntax like this:
"-m local:foo" to add a series of packages in the subdirectory 'foo'
of the 'local' (or 'local64') directory more easily.

Several template vars were added to liveinit.tpl but I had forgotten
to also incorporate those in the upslak.sh script.
|
|
That will cause kdesu to ask for the 'live' password instead of the
'root' password.

Minor version bump in order to release a new Plasma5 Live ISO.
|
|
Main highlight is that PXE booting is working again.
|
|
Note that UEFI PXE-boot is not yet working, I do not know why.
|
|
|

|
The live init script creates a /etc/fastboot file to prevent any
file system check on boot. This is cleaner than hacking rc.S and failing.

- virtuoso-ose is no longer part of Slackware.
- akonadi backend to be used is now called SQLITE instead of SQLITE3

The fairly large version bump is warranted because this is the first
release to support zstd compression. The resulting ISO will boot to
a usable desktop environment almost twice as fast as previous releases
of liveslak. THe runtime behaviour will also be a lot snappier.
This should make a lot of people happy.
Note that I have to keep the XFCE ISO xz-compressed to keep its size
below 703 MB. The other ISOs will use zstd compression, adding roughly
10% to the ISO size but speeding up the Live OS with 60% or more.

Added a new parameter to 'make_slackware_live.sh' script:
-l <localization>
For example, create a liveslak ISO with dutch as the default language
instead of US english:
# ./make_slackware_live.sh -l nl
Using this parameter you can onfigure a different default language
for the resulting ISO image. The default localization if you do not
supply this parameter remains "us" as before.
The boot menu offers a selection of other languages/localizations
to pick from (currently you can select any of 'be br da gb de de_ch es
fr fr_ch it ja nl pt ru se us') but now you can create your own brand
of liveslak ISO with your own language as the default.

The new zstd compression support for squashfs modules allows for a much
snappier system because zstd decompression is 5 times faster than that of
xz (see https://sourceforge.net/p/squashfs/mailman/message/35989805/), but
at the expense of ISO sizes that are at least 10% bigger. The latter means
that we have to do some more pruning of the XFCE and PLASMA5 images to make
these fit in a CDROM and DVD image, respectively.
Here are some initial benchmarks with PLASMA5 Live ISO images,
booting in QEMU (times are in minutes:seconds):
Stage ZSTD XZ
---------------------------------------
Boot to runlevel 4 start 0:39 0:50
SDDM Login Manager visible 0:55 1:26
Plasma5 desktop ready 1:42 3:17
I also tested two of the bigger applications, measuring the time between
entering the command in a terminal and having a usable application window:
Stage ZSTD XZ
----------------------------------------
LO Writer window visible 0:17 0:34
Chromium window visible 0:09 0:14
It is obvious that a big Desktop Environment like Plasma5 where a lot of
binaries have to be loaded from their squashfs modules benefits a lot
from zstd, because after booting, the Plasma5 DE is available in
roughly 53% of the time it takes when using xz compression.
Zstd support in squashfs was added to Linux kernel 4.14. That means,
no customimzation of Slackware is required to make the Live OS work from
zstd-compressed squashfs modules.
In order to *create* these zstd-compressed squashfs modules, you will need
some custom packages at the moment, until they get added to Slackware-current:
zstd and a rebuild squashfs-tools to add the lacking zstd support to
mksqhashfs/unsquashfs.
