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
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!!!
anybody knows where to get an ISO version of the modula-2 compiler for
LINUX, especially FEDORA-28?

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
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,
Does anyone have any idea of what could be going on?
I am running an up-to-date Fedora 27 x86_64 with kernel
Fedora Project Contributor
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
#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

When starting Redshift, I get the following error

the pop up says:
Any word of wisdom? It worked under Fedora 27.
When I upgraded to F28, OwnCloud stopped working. Another reported the same
problem with NextCloud. The problem has been reported in bugzilla  as
Cannot login after upgrading from F27 to F28. Patrick Reeb provided a fix
with a fix-owncloud  script which downgrades php-sabre to F25.
Because both of the Fedora packages of OwnCloud and NextCloud are dated I
decided to use the NextCloud zip package of their current version 13.
Basically what I did was to install Fedora's NextCloud package to get the
basic configuration files and then removed the package so all what was left
was configuration files with a .rpmsave extension. Using the
nextcloud-13.0.4.zip package  I moved the files to my nextcloud
directory from the Fedora's package.
After a few tweaks to /etc/httpd/conf/httpd.conf files, the login prompt
appeared on my localhost/nextcloud. I was unable to configure my
postgresql database from the web browser, so I used the command line tool
 (occ) to finish the install.
I did try the snap install of the nextcloud-server, but couldn't get it to
work. However, the snap nextcloud-client works like a charm.

I just added a crypted partition on my laptop (/home ans swap are
crypted and until now no problem had occured with them) and this new
partition is not mounted at boot, it is only to be mounted by user on
The whole install of this partition, went without any problems: it could
be unlocked and mounted and unmounted and locked by the user without any
problem, BUT while rebooting the laptop the boot process is blocked by
"a start job is running for dev-mapper-chiffre.device (no limit)".
What is this start job, I don't know! Why is it running, I don't
know.... How to recover, I don't know...
There always some problems with start/stop jobs which are running at
boot or shutdown times.
So what can I do to have a NORMAL boot?

I've got a laptop that has started misbehaving on suspend.
About 1 in 10 suspends the laptop fails to fully suspend. It switches
mostly off (screen off, etc.) but some of the motherboard keeps
running. I know some of the motherboard keeps running because:
- the wifi light remains on
- the laptop will get hot because the fans don't start
The laptop does not respond to the power button to wake up. It's
necessary to force halt & reboot the laptop by holding the power button
down for a few seconds.
9 out of 10 times suspend works fine.
This appears to be a BIOS or kernel issue, since the last entries in
the logs are:
May 29 09:02:17 sieve-deschouwer-co-za systemd: Reached target
May 29 09:02:17 sieve-deschouwer-co-za systemd: Starting Suspend...
May 29 09:02:17 sieve-deschouwer-co-za systemd-sleep: Suspending
May 29 09:02:17 sieve-deschouwer-co-za kernel: PM: suspend entry (deep)
-- Reboot --
On a successful suspend I will additionally get:
May 29 08:21:32 sieve-deschouwer-co-za kernel: PM: Syncing filesystems
This started at the same time as I upgraded to F28. The laptop has
previously worked fine since F24 or F25, or maybe earlier.
It's happened with a few different F28 kernel patchlevels.
