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,

Xbox 360 controller on Fedora 32
by Greg Woods
It has been a couple of years (which means 4 or 5 Fedora releases ago)
since I did this, but I used to be able to play Xonotic using my Xbox 360
Wireless controller. Now I cannot get the controller to work properly in
F32 (it works in Windows 10 so I know the hardware is OK).
This most likely has something to do with the move from xboxdrv (which is
no longer available in Fedora) to xpad kernel driver, and/or the move from
the old js driver to evdev. The xpad driver comes with the current kernel,
but what I cannot figure out is how to calibrate the controller. If I run
Xontic with the controller connected, the game world just spins
counterclockwise. This is a symptom of the controller needing to be
calibrated, but I don't know how to do it. I tried using "jscal", but if I
run "jscal -c" to calibrate it, it appears to work but doesn't. I can
immediately run "jscal -t" and it will say it is not calibrated, and
running "jstest" also shows it is not calibrated (several of the axes are
not centered, i.e. show nonzero values in jstest).
I attempted to download and compile xboxdrv, but it does not work due to
Python 2 vs. 3 incompatibilities, and it doesn't look like any work has
been done on xboxdrv in quite some time. If I try to make it, I get this:
root@snowcrash xboxdrv-linux-0.8.8]# make
scons
scons: Reading SConscript files ...
File "/local/src/xboxdrv-linux-0.8.8/SConstruct", line 34
print target
^
SyntaxError: Missing parentheses in call to 'print'. Did you mean
print(target)?
make: *** [Makefile:24: xboxdrv] Error 2
Certainly looks like Python version incompatibility.
Can anybody point me to information on how to use an Xbox 360 controller on
F32, or how to calibrate it when using the xpad driver? I have done a lot
of Googling, but most of the articles I found mention things like "apt-get
install xboxdrv", showing they were written for Ubuntu rather than Fedora
and are wanting to use the xboxdrv driver.
Thank you,

puzzling SELinux alert.
by home user
At least 3 times in the past few days I've seen the same SELinux alert.
I put the text of the details in the attached file "alerts.txt". All 3
occurrences were while using caja to rename or delete a file, though it
does not happen every time I rename or delete a file in caja. These
alerts confuse me. There is no directory "/memdf:"...
-bash.1[~]: cd /
-bash.2[/]: ls -a
. boot etc lib64 mnt root srv system-upgrade usr
.. .cache home lost+found opt run sys system-upgrade-root var
bin dev lib media proc sbin sysroot tmp
-bash.3[/]: ls -a /memfd*
ls: cannot access '/memfd*': No such file or directory
-bash.4[/]:
Also, the directory name (ending with a colon?) looks fishy. Further,
the filename ".nvidia_drv.XXXXXX" looks fishy (but "legal").
The instruction does not work:
-bash.4[/]: /sbin/restorecon -v /memfd:/.nvidia_drv.XXXXXX (deleted)
-bash: syntax error near unexpected token `('
-bash.4[/]:
-bash.5[/]: /sbin/restorecon -v /memfd:/.nvidia_drv.XXXXXX
/sbin/restorecon: SELinux: Could not get canonical path for
/memfd:/.nvidia_drv.XXXXXX restorecon: No such file or directory.
-bash.6[/]:
I gather that a directory and or file (whatever its name really is) are
missing?
How do I fix this?

System Failure?
by home user
I did my weekly patches (dnf upgrade), rebooted, and logged in as a
regular user. A problem popped-up. The top part of the details is
below. I'm not (yet) seeing any other problems. Is this a false
alarm? If not, what should I do?
---------------
not-reportable
The backtrace does not contain enough meaningful function frames to be
reported. It is annoying but it does not necessarily signalize a problem
with your computer. ABRT will not allow you to create a report in a bug
tracking system but you can contact kernel maintainers via e-mail.

Restored f33 on new drive from a tarball now a problem
by Robert McBroom
New drive has the same msdos partition structure as the old. Legacy
system with boot partition on a separate drive and from the root
partition. System boots in mode 3 as specified but entering id and
password flashes some text and returns to the login. Edited the grub
entry to try a graphical boot but still get textmode.
What can be done to get access to f33?
