When I run an install with dnf the program downloads the packages runs
through transaction checks and begins the installation. When it is done
with the installation it just freezes. In the past it would run through
a verification and clean up and then return to command prompt. Any ideas
on correcting this situation would be appreciated.
How can I manage the brightness of my laptop ?
xbacklight -get (or -set)
does not work.
A gui interface would be helpful.

Running F23/XFCE, with firewalld, and having commanded:
# systemctl start sshd.service
shows that sshd is opening port 22, and listening on 0.0.0.0 .
There is no entry suggesting a login attempt is received.
In the XFCE GUI for firewalld, everything is running in zone labelled
- The network interface is bound to the zone 'public'
- SSH service is enabled in zone 'public'
- I've added port 22/tcp to the list of active ports in zone 'public'
- 'Lockdown', and 'panic mode' are disabled
These settings are the same in mode 'permanent' and in mode 'runtime'
sshd config is set to listen on 0.0.0.0 (and ::).
Our LAN uses ipv4, in the range 192.168.0/24 .
This machine is connected to the network, but I cannot log in to sshd
from any machine on the LAN. The client times-out after a few
seconds. Clients do not report a 'rejection'.
If any list readers have any ideas about what else might need to be
set up, or might be going wrong, I'd be very grateful to hear,
I have a machine where I tried to do a system-upgrade from F23 to F24.
The download portion worked fine but after the reboot, the upgrade
process aborted. I'd like to know why, but first I need to clean up the
mess so I can try it again. Right now I have 4782 total packages
installed including 1490 fc24 packages. I haven't checked all of them
but it appears that all are paired with the same fc23 package.
Trying to repeat the download step, I get this result.
# dnf --allowerasing -y system-upgrade download --releasever 24
Last metadata expiration check: 0:23:15 ago on Tue Sep 6 15:53:47 2016.
Error: The operation would result in removing the following protected
Evidently, there are two systemd packages installed:
# rpm -q systemd
No new kernel was installed and the machine is running fine as F23. But
I'd like to get it upgraded...
I tried using "dnf history rollback" but that didn't work, reporting "A
transaction cannot be undone". Since dnf won't erase the extra stuff, I
can probably do it with something like, "rpm erase --force $(rpm
-qa|grep fc24)" but that seems iffy. Better suggestions are very welcome.
(this is almost certainly a kernel issue but here's hoping someone
can give me some guidance.)
once upon a time, i whined pathetically about problems sticking a
samsung 950 PRO M.2 SSD into my ASUS G752VL-DH71 gaming laptop
currently running fedora:
eventually, i tripped over this ASUS forum page:
where one gets the distinct impression that that particular samsung
SSD is not compatible with my laptop, but one is assured that what
does work is the samsung SM951, which i picked up, with still no luck,
still getting early error message:
ata1.00: failed to enable AA (error_mask=0x4)
... etc etc ...
this is the SSD:
and i'm running out of ideas; do i need to roll my own kernel to add
support for this thing? i would have thought that if i don't have
support, the SSD would just be ignored, and not choke the system.
i'm about to do more testing this weekend, but i sure would like

Use ftp to transfer files, but just had issues today in which connection is
made and login works fine, but doing a ls or trying to download a file fails?
Tried with passive on and off? Did use it just the other day. We did have
some power issues, since two of the Island main generators are down, and
they have had 3 hour rolling outages?? I can do sftp connections, and they
seem to work just fine, but anonymous doesn't work with that. Have tried
both using ncftp and regular ftp. Have systems in my classroom that are on a
separate network sitting side by side, and then can not connect. Can connect
with ftp server on same machine using IP, and it works?
Not at the site at moment, but will try to power cycle switches and computers
to see. I can ncftp to servers on campus from off campus, but from inside
campus to same machines doesn't work? Don't know if MIS might have
made some changes??

Have a fresh install of F24. The machine has Nvidia GTX 960 video card. I
would like to enable GPU rendering in blender. Have installed nvidia
drivers from rpmfusion repo and CUDA toolkit from nvidia. Can select now
CUDA as rendering option in blender settings. However trying to render
anything fails. Initially nvcc couldn't compile using gcc-6.1.1. After
installing compat-gcc I have gcc-3.4. Added softlinks to it:
sudo ln -s /usr/bin/gcc34 /usr/local/cuda-7.5/bin/gcc
And same for g++
Now CUDA's kernel compilation fails with the following error:
(334): error: expected an identifier
1 error detected in the compilation of
As I understand the issue is still related to some uncompatible versions of
C++. Maybe not the compiler itself but std standard. Is there workaround?
Anyone using successfully CUDA under F24? There must be thousands of you!
Please give me some hint.

Lennart Poettering has a hate for rc.local. He discusses that somewhere
in his systemd blog. For whatever reason, he dislikes it and thinks that
no-one should use it, or be able to use it. So you must sacrifice the
correct animal, at the exactly correct time, for it to work.
And of course, just as with pulseaudio, systemd does not give meaningful
or useful error messages.
Since most items in rc.local are run-one-time items, the answer is to
NOT USE SYSTEMD.
Create your rc.local file, and chmod it u+x, and then add the following
to your (root) crontab: @reboot /etc/rc.d/rc.local
@reboot in a cron does exactly what it implies: it runs, once at boot
time. See 'man 5 crontab'
Problem solved without systemd.
I have my laptop with F23 with the root partition encrypted with luks,
working great for about a year already.
I had some pending upgrades which I applied today (kernel, glibc and
systemd are the ones that made me open my eyes wide).
The thing is that system starts booting, asks for the password to
decrypt (actually decrypts the partition) but then fails and falls
back to a rescue shell.
Reading the logs there (/run/initramfs/rdsosreport.txt) it seems there
is a Dependency problem somewhere:
Dependency failed for Cryptography Setup for luks-.....
Dependency failed for Encrypted Volumes
I'm able to mount the root partition in the rescue shell and see it's
contents, but I can't get the system to boot correctly.
I've already tried using one of the old kernels (have always 3 around).
Any thoughts on how I can get passed this?

I'm not sure if this is a Samba client issue, or an issue in Dolphin, so
I'm posting to the KDE and General users lists. Is anyone else connecting
to a Windows share and not being able to write to it from Dolphin?
I've got a handful of Windows servers that I regularly download items to my
Fedora laptop and copy over via Dolphin. Up until the F24 upgrade that
is. Originally I thought it was just a bug that would be addressed shortly
after F24 was released. Now, though, I can still connect to the shares,
but I cannot copy/paste to them. None of them. Is there something simple
FYI, it's not a permissions issue as I can login to those shares from a
Win10 VM I have on my laptop and write to those same shares without
trouble. The Windows servers, other than being patched are the same
versions (ie no upgrades recently), so I'm at a loss as to the problem.
