need help with printer set-up.
by home user
I bought a new hp laser jet pro mfp m180nw. This morning, I installed:
* hplip-gui
* hplip
and all their dependencies. “dnf upgrade” shows they and cups are up-to-date.
As root, I used cups to try to install my new printer (HP LaserJet Pro MFP M180nw). The printer was already powered on and connected to my workstation’s tower via USB cable. But when I try a print test from cups, I get page after page, each having several seemingly random strange characters, but otherwise mostly blank. I had to power down the printer to cut the waste of paper.
As root, I tried to launch “HPLIP Graphical Tools”. Nothing appeared to happen.
Logged in as the non-root administrator, when I launch “HPLIP Graphical Tools”, I get an error GUI saying
“No Installed HP Devices Found”
and a few seconds later, another error GUI saying
“HPLIP Status service”
and
“No system tray detected on this system. Unable to start, exiting.”
The first GUI suggests running the hp-setup (a button is provided). I do that. I get another GUI. I select as a “Connection (I/O) Type” the USB option. As advanced options, the search term field is blank, and the type is set to “All devices/printers”. I click “Next >”. It says “No devices found.”.
The first error GUI also suggests using the cups web interface. There, everything looks ok to me, but I’m (obviously) no expert in these things.
What’s wrong? How to I get my printer working? I’m in Fedora-27; Gnome.

Dell laptop for Fedora (XPS 13 or Latitude 7490) or worthier
alternatives?
by Ranjan Maitra
Hi,
I have two alternative Dell options (unless more suggestions come in re: what I should get).
The employer's standard fare which entails:
#1. High Performance, Daily Use 14” Laptop: Latitude 7490
Processor: Intel Core i7-8650U
Memory: 16GB
Storage: 512GB SSD
Graphics Card: integrated
Wireless: integrated
LCD: 14.0” LCD (1920x1080) Non-Touch Anti-Glare LCD with Camera
Camera: Light Sensitive Webcam and Noise Cancelling Digital Array Mic
Comes with Windoze, but other than the fact that I will be paying the monopoly tax and stripping it off, it is not a big deal.
#2. Dell XPS 13 9370 Developer Edition
Processor: Intel Core i7-8550U
Memory: 16GB
Storage: 512GB SSD
Graphics Card: integrated
8th Generation Intel(R) Core(TM) i7-8550U Processor (8M Cache, up to 4.0 GHz)
16GB LPDDR3 2133MHz
Thermal Plate for SSD
512GB Solid State Drive
Intel(R) UHD Graphics 620
13.3'' 4K Ultra HD (3840 x 2160) InfinityEdge touch display,
Killer 1435 802.11ac 2x2 and Bluetooth
52WHr Battery
Comes with Ubuntu 16.04 (no tax) but which will be used to boot and see if it is powers up before being stripped for Fedora 28.
The XPS13 has a slightly lower spec for the processor (maybe, because it appears to be of slightly earlier stock - 8550U versus 8650U) but the specs are fairly comparable. The resolution is no doubt better for the XPS13. This configuration will cost me $700 more than the Latitude. Which I am willing to pay unless there are technical reasons for preferring the Latitude. The XPS13 is about a pound lighter from what I can tell.
While we are at it, any other suggestions from DEll or others?
Many thanks in advance and best wishes,
Ranjan
PS: I have a 5-year old XPS13, fabulous machine and I am typing this e-mail on it right now. But it is 5-years old and may die so in need for a replacement.

F27 to 28 Upgrade of Postgresql
by Clifford Snow
I'm excited to see Postgresql 10.3 included with F28. Has anyone upgraded
to 28 with an older version of Postgresql? Did the Postgresql do the
upgrade or did you do a dump and restore of your databases?
Thanks in advance,
Clifford

Duplicate email from Bodhi
by eqie@mailbox.org
Hello,
whenever I comment on a proposed package update in Bodhi I receive *two*
identical emails regarding the comment I added. This does not happen
with comments made by someone else, i.e. I only receive a single
notification email.
Any idea why this happens?

Kernel task 276 consumes 100% of io bandwidth on boo drive
by JD
276 be/3 root 0.00 B/s 0.00 B/s 0.00 % 99.85 % [jbd2/sda3-8]
When I booted, drive was clean!!
All my current running processes (i.e. ones I started), are quiescent.
Whith glitches like these, it makes a LOT more difficult to honetsly tell
students why they should switch to Fedora, "because it is better????".

Unmount delayed -
by Bob Goodwin
.
I've had this problem for more than a year but usually it only bothers
mefor a moment and I move on. Today it was a bigger annoyance when I was
trying to diagnose a problem with a flash drive.
When I mount the device my clicking on mount on the desktop icon that
pops up when it is plugged init then takes 2 minutes, I timed it today,
to release after clicking on unmount. I would like to reduce that to
something reasonable likeimmediately or no more than a few seconds.
This is with xfce and lightdm on Fedora 27, but it has been doing this
for several versions of Fedora. I use the flash drive to save audio
books, keep reusing the same device and only see the problem when I save
a new audio book, perhaps once a week, so I just accept it ...
Any thoughts appreciated,
Bob

F28: gnome-shell crashes when using external displays
by Stefan Hübner
Hi,
I upgraded to Fedora 28 two days ago (May 2nd). My laptop usually is
mounted to a docking station with two Dell displays attached.
Since this morning I cannot start a gnome session anymore. After login the
shell crashes gets back to GDM. In fact it's enough to hover over the top
right drop down menu to crash GDM.
Also interesting: no fonts are displayed when using external monitors.
If I restart the machine without external monitors, everything works
flawlessly.
journalctl reveals the following messages (there's also a core dump, which
I omit for brevity):
Mai 04 11:00:15 4delsthubner02 gnome-shell[2601]: Failed to allocate

This indicates a bug in
someone's code. You must ensure an error is NULL before it's set.
The overwriting error
message was: Sliced texture size of 16 x 16 not possible with max waste set
to -1
Mai 04 11:00:15 4delsthubner02 systemd[1]: Started Process Core Dump (PID

What's going on here?

qucs simulation fail on missing library
by patrick stanistreet
I have been trying out a package qucs for electronic circuit design and simulation.
I can use the software to create a simple design but the simulation fails on a missing
library. I tried compiling qucs from source and freehdl is a dependency. I think the
problem is with freehdl as I tried and failed to get it to compile.
qucs simulation fails on libfreehdl.la
I think something in gcc or g++ might not be creating this file during compilation and
it might be some kind of policy change?

printer and Fedora support.
by home user
I'm having to replace my 5-year old desktop printer. Like any good project, I start with requirements!
1. desktop printer.
2. the manufacturer provides real support for the printer running on Fedora as well as windows-7.
3. has printing, scanning, and copying.
4. color and black-and-white, colors are correct when printing from Fedora as well as when from windows-7.
5. at least 600 dpi.
6. USB cable connection (not ethernet or wi-fi) between printer and workstation's tower.
7. either laser or LED, not ink-jet (I'm in a very low-humidity climate).
I am especially concerned with requirement #1, and that's why I'm asking this list. What fulfils all the above requirements?
Support needs to be more than simply providing a driver for me to download. The at least 600 DPI has to be real, not merely "effective", "simulated", etc. My now dead printer, a Xerox Workcentre 6015, claimed either 1200x1200 or 1200x2400 resolution, but I only got 600 real dots per inch, both in windows-7 and in Fedora. When printing from Fedora, colors were not even close, but were ok when printing from windows-7.
Which is better overall: laser or LED?
Thank-you for your advice.
Bill.
