Wacom Bamboo Ink?
by Matthew Saltzman
Has anyone used a Bamboo Ink or Ink Plus stylus with Fedora?
Fedora 31, up to date. Lenovo Yoga X1 second generation. Trying to use
a Bamboo Ink Plus stylus. I can pair it via Bluetooth, but I can't get
it to connect after pairing. When I attempt to connect, the Bluetooth
connection dialog window spinner runs for several seconds, then
indicates the connection is off.
Any advice about things to install to support this device would be much
appreciated.
If the Ink Plus can't be made to work, I can downgrade to the Ink. If
anyone has a better suggestion for a full-sized stylus, I'd welcome
that too.
The built-in Yoga stylus works fine, but it's not comfortable for
significant pen work.
Thanks in advance.

Things to monitor/scan for security on a Fed VM
by bruce
Hi/Morning.
This is a continuation of my looking to nail down what should be
Monitored/Scanned to secure a Fed server/VM.
I've looked over a number of Monitor apps (Solarwinds/Nagios/Zabbix/etc).
Can't really find a good list of the things that should be monitored, so
I've compiled the following list.
I'm thinking the monitoring/scanning process needs to check for,
or handle the following:
-user attempts to access a system/ssh interaction/- logins/access
there's a ddos on one of the VM/webapps
rootkit/file issue
possible intrusion attempts
-for ports
-for log files
-for user accounts
files/dirs -perms/user owner
log files
system/services -- required services running... invalid services disabled
cron
dirs/files/filesystem
website
db
config file issues
rootkit issues
malware issues
vulnerability issues -- vuls.io
selinux
partitions for the drive
firewall
mysqld
httpd
nfs
sshd
-php valid
-python valid
-package scan
-pip scan
-pecl scan
-should the libs be scanned?
-how to scan/check for/alert on invalid apps running?
config files -- valid/invalid
Feel free to add or comment on anything I've listed.
Once I narrow down the list, I'll figure out which tool/dashboard to use
for the Monitoring/Scanning. I might have to also have a separate Dashboard
(ELK?) to handle the log analysis/display.
Thanks

Motherboard recommendations
by Fulko Hew
I'm looking for the best bang for my buck, and of course
Linux (Fedora) compatibility. My criteria are simple:
- inexpensive
- best bang for the buck
- must have PCIe 3.0 x 16 slot
If I pick Intel based, I'm pretty much assured everything will work,
but it seems that going AMD will get me better bang-for-the-buck,
but ... will all the parts work with Linux?
I'm currently looking at a Gigabyte B450M DS3H with an AMD Ryzen 5 3600 CPU.
Does anyone have experience with it, or can recommend anything else
comparable and 'current'.
Thanks

F31 - getting UHD external monitor to display at 3840x2160
resolution
by Ranjan Maitra
Hi,
I recently got myself a UHD monitor.
https://www.amazon.com/dp/B07JXCR263?tag=aboutcom02lifewire-20&linkCode=o...
However, when I connect to my 3840x2160 resolution laptop and use xrandr (through HDMI, supplied with the monitor) I do not even get an option for 3840x2160. Here is what I get:

Why is this so, and what do I do to get the UHD resolution? I would really like to match my laptop resolution (in fact, this was why I bought this monitor).
The box says 4K UHD 3840x2160 resolution. Any suggestions?
Many thanks,

Slow down in operation and shutdown issue
by ToddAndMargo
Fedora 31, x64
Xfce 4.14
Shutdown hangs:
https://bugzilla.redhat.com/show_bug.cgi?id=1815686
Hi All,
Randomly and not associated with any particular program,
my system will slow down. It becomes obvious when I can
type faster than letters appear. And when this happens,
a reboot will fix it.
But the shutdown and reboot process hangs when the
slowdown appears. After the shutdown/reboot sequence
gets to "Target Reached Power Off" (or restart), a
delay of about two minutes and then I get my CPU
registries displayed over and over.
Looks like this:
repeating CPU registries:
https://bugzilla.redhat.com/attachment.cgi?id=1672106
This is my dmesg:
# journalctl -b --no-hostname -k > dmesg.tx
https://bugzilla.redhat.com/attachment.cgi?id=1672107
This has happened three times in one day. It has also
gone for days without an issue.
And again, no particular program either. I initially
thought it was qemu-kvm, then VLC, but it has happened
with neither running. And just sitting at the desktop
with the screen saver running.
Any words of wisdom?
Many thanks,

a general observation
by David
Phoronix has a pre-review of one of the rc isos of
Fedora 32.
In the comment section, was a critic who was not impressed with Fedora 32.
I have seen this argument or opinion on YouTube Linux reviews and various
forums.
But all those reviewers do a simple install in VirtualBox, and look at
what theme-ing options are available by default and what backgrounds are
preinstalled, and what software is pre-installed, and then compare that to
something else like Linux Mint or Elementary OS or Zorin, and after an hour
or even less they draw the conclusion that nothing is new, nothing has
changed,
and that Fedora is still the same old ideology of Linux nerds wanting to
keep
Linux as nerdy as possible.
The critics often use terms like "less polished," etc.
The defenders often say, that all the codecs and such must use 3rd party
repos
due to laws in various countries, that for whatever reason may not apply to
the
critic's favorite distro.
I see the benefit to Fedora, as the huge fan-base, the forums, the
web-pages, the
dedicated members who want the latest packages, even if the argument for
having
them is "whooped-de-doo."
It is really hard to please all the gnome3-haters. They use terms like,
"gnome3 upsets
my workflow." And although Fedora offers numerous DE's, it does appear
that gnome3
is the priority. I feel distros should prioritize a DE. OpenSUSE
has a great plasma version,
so why re-invent the wheel ? Elementary allegedly has a great pantheon
version, ( I have not
yet tried that ), but still, the point is why should Fedora 32 try to be
like them ?
Fortunately, I am content living in Rawhide with gnome3 on hardware, and
can get my task done.
In a week or so, I will not be surprised to be using kernel
5.7.0.rc3-git*something. And I won't have
to make any noticeable effort to install it. Try that in Linux Mint, or
Ubuntu or Debian, or Elementary
or Zorin, etc. And in less than a month, systemd will likely update
from 245.5-2 to 245.5-3, and again,
it will be a routine simple thing, and will likely not break my install.

Problem with Brother scanner
by Robin Lee
Hi list
I recently got a Brother scanner/printer for my Fedora 31 desktop. I've
installed all the drivers from Brother and the printing part works
fine, but not scanning.
When I launch simple-scan, either as root or normal user it can't find
any scanner. Although it will show up in Settings -> Devices -> Colour
on two lines, both as a scanner and a printer. lsusb also shows two
devices.
What's interesting is that at each boot the following shows up in the
logs
systemd-udevd[1103]: Configuration file /etc/udev/rules.d/65-brother-
brscan4-libsane-type1.rules is marked executable. Please remove
executable permission bits. Proceeding anyway.
systemd-udevd[1103]: /etc/udev/rules.d/65-brother-brscan4-libsane-
type1.rules:9 Invalid key 'SYSFS'
systemd-udevd[1103]: /etc/udev/rules.d/65-brother-libsane-type1-
inst.rules:14 Invalid key 'SYSFS'
The content of 65-brother-brscan4-libsane-type1.rules is as follows
ACTION!="add", GOTO="brother_mfp_end"

#MODE="0666"

Any ideas, what to do?
