GDM Login Screen Doesn't Show Primary User After F30 Upgrade
by Tim Evans
I have experienced similar issues with two different F29->F30 upgrades
via dnf. Although what happened wasn't identical on both upgrades, the
results were the same: After upgrade/reboot, the GDM login screen does
not show the primary (previously existing) user name (UID 1000).
In the first upgrade, I was forced to create a new user after the
upgrade on first boot, as if this was a new install, despite the
existing userid. The previously existing user name does not show up on
the GDM login screen. Instead, only the *newly* created username (UID
1001) shows.
In the second upgrade, the firstboot-create-a-new-user didn't occur, but
the previously existing primary user name (also UID 1000) does not show
on the GDM login screen. Instead, only secondary username (UID 1001) shows.
In both cases, the primary userid can be accessed by clicking the "not
show" link on the GDM login screen and manually entering userid and
password. Of course, this is a fairly simple workaround, but is
nevertheless an inconvenience.
Where does the GDM login screen pull the info for the primary userid?
/etc/passwd and /etc/group don't show anything that looks like a flag
for this.
The files in /var/lib/AccountsService/users/ appear to contain some sort
of flag, but they are apparently created on login, rather than being
permanent. On both systems the primary userid (UID 1000) is shown as:
SystemAccount=true
While the file for UID 1002 is:
SystemAccount=false
Modification time on these files is same as the userid's last login, and
manually changing the SystemAccount flag has no effect; it's set back on
next login.

nvidia-kmod Build Fails on Recent F30 Debug Kernels
by Tim Evans
Failure appears to occur only with debug kernels. For example, from

I think this message indicates there is only one GPU in the Nvidia
adaptor. lspci reports the adaptor is GeForce GT 730
Finally:
Jun 29 11:12:07 osprey systemd[1]: Condition check resulted in Fallback

What does that last message say? The fallback was skipped or the
condition check was skipped?
Thanks.

grub2 set root
by Patrick Dupre
Hello,
How can I understand this:
set root='lvmid/W6k0N8-5JlY-Xntk-w8Yi-Ss1F-I0IY-VzPRU3/vE133D-nAZ8-ltwF-2o4x-H6Cs-a9l5-19IRw4'
It is not in the list of partitions
Can I change it?
In the past it was clearer (probably before efi)

Hplip.
by Ger van Dijck
Hi all ,
It seems the whole world has problems with this piece of beautiful
software .
Hp-setup functionates fine : After the setup run HP-check and be sure that
the scanner is detected .
When upgrading I never had any problems ; When I had to do a new install
very often the scanfunction did not functionate anymore . Just return to
the former HPlibrairies .
Regards ,
Ger van Dijck .

HP printer device manager not seeing HP printer
by Robert Moskowitz
The hits on F30 keep coming. I can't remember an install where I had so
many things not work right.
Anyway.
I went through the standard Xfce printer setup and connected to my HP
8600 over port 9100. I have printed a number of items to this printer.
But I want to use the scanner, like I have set up on my old F28 system,
so I have installed hplip-gui, xsane, and such and started hplip-gui.
It is telling me I have no HP printers installed.
I went through localhost:631 and installed the printer again. It now
shows there as well.
HPlip-gui still not seeing the printer.
What might I be missing here?
thanks

PCYNLITX project and its innovations ( for multi-threading )
by Erkam Murat Bozkurt
Previously, I have presented my project to you. The current name of my
project is PCYNLITX.
PCYNLITX platform offers completely new programming technology which can be
named as Programmable Meta-Programming System and PCYNLITX platform is just
a particular application of this new programming methodology.
Basically, PCYNLITX is an intelligent integrated development environment (
IDE ) which can produce an application-specific multi-threading library
based on your needs and assists you in multi-thread software development
process. PCYNLITX is not a multi-threading library. Instead, it is a
multi-threading library generator. You can find out very comprehensive
documentation about pcynlitx project from both project web site and source
code repository. The addresses of the project web page and source code
repository are given in below links.
www.pcynlitx.tech
https://sourceforge.net/projects/pcynlitx
The outcome of the PCYNLITX platform acts as an autonomous thread
management system provides deterministic scheduling of the threads. You can
control the thread with the numbers given by you and determine the relation
of the threads. In other words, different from the other multi-threading
tools, you can directly schedule the threads independently from the
operating system.
The scientific journal of the project is under review on IEEE Transactions
on Software Engineering.
Currently, the PCYNLITX platform only works on Linux based operating
systems and the other versions ( Windows and McOSx ) are under development.
The License of the PCYNLITX platform is GNU GPLv3 Free Software License. You
can find out many other documents including scientific introduction of the
project (“Technical Introduction” ), code examples and GUI tutorial form
the project web sites. You can also find out a documents introducing
std::thread programming, pthread programming and OpenMP programming on the
web sites.
I am always waiting your valuable comments and contributions.
Thanks and best regards.
