Screen rapidly blanking on and off
by Ted Roche
I've run into a problem with my Dell Inspiron where the screen blanks
every second, unless I'm typing or moving the mouse. Spinning the
mouse around the screen will keep the screen lit, while typing will
blank between keystrokes, and I'm a fair 70 wpm typist.
This ia Fedora 23 64 bit installation, and I've seen the problem on
all three of the current kernel installs,
Linux jupiter.in.tedroche.com 4.7.4-100.fc23.x86_64 #1 SMP Thu Sep 15
18:48:53 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
4.7.4, 4.7.5, and 4.7.6.
Nothing in the logs stands out and unusual.
Suggestions on what I might look at to troubleshoot ths?

WD My Passport Ultra 3T usb drive problem
by Gregory P. Ennis
Everyone,
I just purchased 3 WD My Passport Ultra 3T usb drives that I had hoped
to use for archive files for some digital images.
Looks like WD has made it difficult to use for Linux. The google
searches that I did stepped me through mounting it on a Windows 10
system and then formatting it with nts. Unfortuantely, when I tried to
connect it to Fedora 24 I am still not able to recognize it to mount
it. All of the /dev/sd* entries were the same before and after I
plugged it in. Smartmontools appears to recognize it when it is
plugged in a usb port, but pauses and does not finish its execution to
completion. gparted scans all devices and does not finish when the
drive is plugged in a usb port.
Has anyone in the group figured out how to use these drives?
Thanks for you help!!!!

md-raid1 + lvm
by Gour
Hello,
I’m new Fedora (f25-beta) user considering to fully (after having Fedora
on my netbook) migrate to Fedora.
At the moment I run Debian (Sid) and have two hard disks: 1x1TB and
1x2TB (one old 1TB disk recently died) and have the following layout:
sda: 1 - BIOS boot
2 - md-raid1 (root, xfs)
3 - md-raid1 (home, xfs)
sdb: 1 - BIOS boot
2 - md-raid1 (root, xfs)
3 - md-raid1 (home, xfs)
4 - swap
5 - backup partition
Now I’ve a feeling that, somehow, Fedora favours usage of LVM
partitions…Otoh, I’ve been told that using LVM on top of RAID(1) might
not be the best solution, so wonder whether you recommend to keep the
same layout as on Debian or to put my raid-1 volumes in LVM containers?
Another concern I have is in regard to separate /boot partition which I
was not using on Linux for quite some time, but see that Fedora’s
automatic layout does create it?
Sincerely,
Gour

Dual boot
by Celso Viana
Dear All,
I had a setup with "Windows 10" and "Fedora 23" dual boot (UEFI). I
installed the "Fedora 24" on this machine and the installer failed to
detect the most "Windows 10". Does anyone know how to reconfigure /
reinstall GRUB to Windows appears in the boot menu?
Thanks

starting remote firefox via SSH
by bruce
Hi.
This is a "continuation" of the issue of starting firefox for a diff
user on a box.
If one logs into (SSH) into a remote box, and wants to start firefox
on the remote machine, such that all firefox operations occur on the
remote machine..
Different sites suggest setting the DISPLAY var, as well as xauth,
etc.. none of which seem to work.
The local/remote are both centos/fed.
The goal:
To be able to SSH into a remote box, and run a py script that
initiates a py/selenium binding/process to use firefox.
-This requires that the remote box be able to start/run firefox
for the user that the SSH session was started as/under.
The SSH/Firefox issue:
-How to SSH into the box, and start firefox?
(Already set up the keys, to allow ssh into the box vai ssh 192.168.1.4)
Tried:
ssh 192.168.1.4
foo@box1# DISPLAY=0: firefox
---ERROR: cannot open display: 0:
foo@box1# export DISPLAY=0:
foo@box1# firefox
---No protocol specified
---ERROR: cannot open display: 0:
This has to be simple!
Any thoughts??

nc missing option -z
by Suvayu Ali
Hi,
I used to use netcat to check if a particular host is up or if I have
internet connection before I run a few scripts. I would use the -z
option in particular. But now I see that has been removed:
$ nc -z imap.gmail.com 993 && sync-my-email.sh
ncat: invalid option -- 'z'
Here is the excerpt from the old manual page:
-z Specifies that nc should just scan for listening daemons, without
sending any data to them. It is an error to use this option in
conjunction with the -l option.
Any ideas what happened to it? What can I use as replacement?
Thanks for any ideas.

install.img
by CLOSE Dave
I need a copy of the install.img file for Fedora 20. It doesn't seem to
be present in archives.fedoraproject.org or in the F20 netinstall ISO.
Can anyone point me to a copy?
