video display problem -
by Bob Goodwin
Until recently VLC would display .3gp video clips from an iPhone full
screen on this 24" monitor. Now they are very small, perhaps less than a
two inch square.
This is the rpmfusion vlc on Fedora 27.
I suspect Apple has changed something. Am I the only one seeing this
problem? Is there a fix for it?

[F28] Unable to use ACM LaTeX class with pdflatex
by Marco Guazzone
Hello,
I'm using the latest ACM LaTeX class (version 1.53):
https://www.acm.org/binaries/content/assets/publications/
consolidated-tex-template/acmart-master.zip
I've installed the required packages.
With Fedora 27, no problem.
Instead, with Fedora 28, when I run the following command:
$ pdflatex sample-sigconf
I get the following error:
kpathsea: Running mktexpk --mfmode / --bdpi 600 --mag 0+540/600 --dpi 540
txsys
mktexpk: don't know how to create bitmap font for txsys.
mktexpk: perhaps txsys is missing from the map file.
kpathsea: Appending font creation commands to missfont.log.
)
!pdfTeX error: pdflatex (file txsys): Font txsys at 540 not found
==> Fatal error occurred, no output PDF file produced!
As an alternative, I can use latex+dvipdfmx commands to first generate a
DVI and then convert it to a PDF. However, the resulting PDF looks
different from the one contained in the acmart-master.zip file.
I've just submitted a bug on Bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=1595278
Any idea?
Thanks for your help.

It seems latest updates have solved my problems, both if network cable is
connected and without it.
My network card on laptop is this one from "lspci -v":
05:00.0 Ethernet controller: Qualcomm Atheros AR8151 v2.0 Gigabit Ethernet
(rev c0)
Subsystem: ASUSTeK Computer Inc. Device 1851

Kernel driver in use: atl1c

It seems combination of latest kernel (4.16.6-202.fc27.x86_64) and latest
packages I have again my old behavior.
With network cable connected to an automatic dhcp connection:
[g.cecchi@ope46 ~]$ sudo systemd-analyze time
Startup finished in 1.386s (kernel) + 1.328s (initrd) + 8.891s (userspace)
= 11.606s

[g.cecchi@ope46 ~]$ sudo systemd-analyze blame

1.019s abrtd.service
819ms lvm2-monitor.service
716ms systemd-udev-settle.service
712ms libvirtd.service
. . .
Without network cable connected (and without wirelsss autoconnect)
[g.cecchi@ope46 ~]$ sudo systemd-analyze time
Startup finished in 1.389s (kernel) + 2.002s (initrd) + 8.702s (userspace)

cpupower
by JD
Manpage of cpu power make no mention of the
selection of governor.
How can set the governor to be the user mode governor
instead of the performance governor and not the ondemand governor?
If I can permanently set that governor, next I want to
set the cpu frequency (for all cores) to 2134000Hz permanently.
Reason I am posting this is because the normal speed of the cores
is 2.8GHz, and that is causing numerous kerneloops interrupts (overheating).
Fans are at full speed all the time, as I can hear them :) :)
When I set the speed manually (as root) like this:
for i in 0 1 2 3 4 5 6 7 8; do
echo 2134000 > cpu$i/cpufreq/scaling_max_freq
done
then kerneloops are greatly reduced.
Every kerneloops is accompanied by mce:
So, it has to be the heat.
But I do not want to do this loop every time I boot up.
I want to have set once and for all!!!
Thanx!!!

>60gb of reserved memory??
by Susi Lehtola
Dear all,
I just noticed a very weird problem on my workstation. Although the
machine has 64 GB of RAM installed,
$ head -n 1 /proc/meminfo
MemTotal: 2400748 kB
that is, only a few gigabytes are actually available.
Unfortunately I don't have physical access to the machine, which is a HP
desktop bought last fall. According to dmesg, the model is something like
[ 0.000000] DMI: HP HP EliteDesk 800 G3 TWR/8298, BIOS P01 Ver. 02.06
06/09/2017
Also according to dmesg, it appears that the kernel *does* see all 64
gigs, BUT OVER 60 GB IS RESERVED MEMORY!!
[ 0.000000] Memory: 2326720K/66985176K available (12300K kernel code,
1568K rwdata, 3836K rodata, 2124K init, 1368K bss, 64658456K reserved,
0K cma-reserved)
Does anyone have any idea of what could be going on?
I am running an up-to-date Fedora 27 x86_64 with kernel
4.16.15-200.fc27.x86_64.--

Could LightDM be bad?? (LONG)
by Beartooth
I keep three PCs on my desk, running Fedora behind a KVM switch: #1 is
my present biggest fastest, #2 its predecessor, and #3 that one's
predecessor; I try try keep them as similar as is feasible.
They've all been having troubles for months, which have only gotten worse.
Under F27, they kept filling up with some sort of cruft, to the point
of refusing dnf upgrade; but when I found any of the cruft, it was in
places where I dared not lay about me with a cyber-battleaxe. I jumped
to F28 the day of release.
At this point, none of the three is usable at all without some dodge or
other.
#2 and #3 have each been wiped, twice, with different releases of DBAN,
followed each time with a netinstall of F28 with Mate, and then dnf
upgrade daily. All their boot messages show green OK. Those end with
"Started Light Display Manager."
Usually they proceed to a login box in front of the F28 display of blue
light-conducting fibers. That accepts my password, churns a little way,
and ends with a monitor full of blue horizontal lines, plus a few white
lines in the middle and at the bottom; there is nothing legible.
By doing Alt-Ctrl-F2, I get a display which lets me log in as root; I
keep doing dnf upgrades, and trying startx, every day. I also reboot
whenever there's a kernel change.
Startx always flashes a couple times, then fails with a few lines of
text, beginning with an attempt to adopt my monitor size (called "1920
1080" -- not 1920x1080),losing contact, and ending by saying that the
Xserver "terminated successfully."
I'd like to try replacing LDM with something else; how do I do that??
(I like Mate well, and would prefer not to swap it out,too)
Finally, #1 has two F28 kernels -- which do no better than on #2 nor #3
-- and a rescue kernel from F26. Sic. Twenty-six, not 27 nor 28. But
that rescue kernel does support almost my whole GUI (I miss Pan badly.),
and I don't have to descend to the console.
#1 got F28 by upgrading with dnf from F27, and still has a lot of stuff
on it that I'd rather copy to #2 and #3 directly than by way of solid
state storage, if I dare risk malware. (I don't know where else all the
cruft could have come from, apart from malware, but I hope someone here
does.)
