F33 just pretends to print
by Michael Hennebry
I have a Brother HL-L2360DL that I'd thought I'd finally managed to install.
I had to go to the Brother website to get a script to run.
The instructions for the script had the wrong name for it.
None of the default options for Brother printers came close.
The CUPS adminstration "web" pages say the right things:
Idle, accepting jobs, two completed jobs.
Nothing actually prints. Not even a test page.
The printer never comes out of deep sleep.
How do I fix this?
It worked with Centos 7, but I do not know what I did.
In my experience, there is no such thing as a small problem when it comes to
installing a printer on Linux:
Either it just works or it requires a mighty effort.
I am getting mighty tired of mighty efforts.
BTW how do I change the default from single- to double-sided?

Improper shutdown, now Kernel panic.
by murph nj
Hi all:
I've got an odd problem that I was hoping for some help on.
The laptop was previously working fine, I am running F30, updated regularly.
I've got an Acer laptop that has been shutting down suddenly. (I
suspect a bad battery, working on that.)
After a sudden shutdown last night, I now get a kernel panic on boot
right after "Starting Switch Root..."
I was able to boot from a USB stick, and was able to read the journal,
but I didn't see anything obvious to help.
I was able to get all of my data off of the (encrypted) disks, so
that's not a problem, but I don't want to just give up, and wash and
reload too quickly.
Any suggestions?
Thanks,

slow startup process and dmesg times
by Anil F Duggirala
hello,
I am looking at output from dmesg on my laptop and there appears to be a
time when a process takes longer than what might be expected and I think
this may be reducing my startup speed.
My question is, is it normal for there to be a jump in time (timestamp)
from 7 seconds to 18 seconds. And then from 21 seconds to 30 seconds?
Are these processes slowing down my startup?
dmesg output:
https://pastebin.com/HhDyURjd
thank you.

Long wait for start job
by Frank McCormick
Just did a new installation of the basic fedora 34 desktop the one which
provides a bunch of basic window managers using a netinstall iso.
The boot is interrupted for a longtime (2 minutes) while
a start job runs for wait for udev to complete initialization.
The timeout is three minutes and it almost reaches that point
before continuing.
I have looked through
the syslogs but the only obvious problem is a core dump
by alsa control which I don't understand because prior to this running
Fedora 33 nothing similar happened.
Need some advice on how to debug this.

DNF not Installing all Updates?
by Stephen Morris
Hi,
I have just done a sudo dnf upgrade on F34 which I think upgraded
1311 packages. After the update finished I rebooted F34 and then ran
discovery and it was still telling me there was 628 MB of F34 Platform
updates to put on, which I did put on. Why is dnf not installing all
updates that are available? Is there a configuration that needs to be
done to alleviate this that is not done in an "out of the box" install,
or, is this telling me that we shouldn't be doing updates with dnf we
should be using Discovery instead?
regards,
Steve

Creating a user-level systemd unit
by Patrick O'Callaghan
I'm trying to get a specific service to start on login, and the usual
method (KDE Autostart) isn't working so I'm trying to do it with a
systemd unit:
$ cat startinsync.service
[Unit]
Description=insync-headless service
After=default.target
[Service]
ExecStart=/bin/sh /usr/bin/insync-headless start
KillSignal=SIGINT
[Install]
WantedBy=default.target
The docs say that the place to put the unit file is given by:
$ pkg-config systemd --variable=systemduserunitdir
/usr/lib/systemd/user
So I copied the file there:
$ ls -l /usr/lib/systemd/user/startinsync.service
-rw-r--r--. 1 root root 177 Jun 29 12:31 /usr/lib/systemd/user/startinsync.service
and tried to enable it:
$ sudo systemctl enable startinsync
Failed to enable unit: Unit file startinsync.service does not exist.
I'm out of ideas.

Questions on creating RPM Package??
by Michael D. Setzer II
Saw all the messages on Clonezilla, and brought up
a question I'd ask a long time ago, and a new one.
Had asked about process to do an rpm package,
and had gotten a suggestion to going a list on it, but
turned out the list was dead, and had had no post
for years, so that was a dead end.
Have been the maintainer of the G4L disk imaging
program since 2004, and build it with Fedora as the
build system. Have been able to run it from the CD,
USB or even from grub2 menu by manually adding
it. Doesn't have all the bells or options that
Clonezilla has, but does things.
The grub option to add just required putting a
kernel file and ramdisk.lzma file into boot directory
and then using a 40_custom file.
# !/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu
entries. Simply type the
# menu entries you want to add after this comment. Be
careful not to change
# the 'exec tail' line above.
menuentry G4L {
linux /bz5x12.13 root=/dev/ram0 telnetd=yes
initrd /ramdisk.lzma
}
menuentry G4L_NOSMP {
linux /bz5x12.13 root=/dev/ram0 telnetd=yes nosmp
initrd /ramdisk.lzma
}
menuentry G4L_FailSafe {
linux /bz5x12.13 root=/dev/ram0 noapic noacpi
pnpbios=off acpi=off pci=noacpi nosmp
initrd /ramdisk.lzma
}
That would then add options to the grub boot menu
similar to how memtest worked to add option. It
would load kernel image, and then g4l in ram to
run. Looked at memtest, but note that they don't
have an option with the EFI version, which was my
new question with shift to more systems using that?
Issues with creating signed kernels?
Wondering if there might be information or
someone might know of a list or page?
Thanks.
