Alternatives to Theme Font size changer Firefox plugin?
by Sam Varshavchik
The popular theme font size changer Firefox plugin,
https://addons.mozilla.org/en-US/firefox/addon/theme-font-size-changer/, no
longer supports Linux.
The default Firefox font size is too small for people with poor eyesight. As
far as I can tell, the only thing that official "Firefox themes" do is set a
background image for the UI. As Benny Hill would say, biiiiiiiiiiiiig …deal.
The top-ranked comment on that extension page suggests hacking "userChrome-
example.css" in ~/.mozilla/firefox.
$ find ~/.mozilla/firefox -name userChrome-example.css -print
$
There goes that idea.
Googling around the only other suggestion I found was to hack
layout.css.devPixelsPerPx setting in about:config. All that did, apparently,
was making the Firefox UI elements themselves bigger, but their font size –
the menu and the URL bar – remained exactly the same.
Anyone has other suggestions?

Taskbar Panel in Plasma Won't Autohide
by Stephen Morris
Hi,
I am trying to get the Taskbar Panel to autohide, but when I click on
the options button in the panel, the left, right and center options are
permanently highlighted but seem to function in terms of moving the
indicator that reflects which option is active. Also the 'Always
Visible', 'Auto Hide', 'Windows can Cover' and 'Windows go Below'
options are also permanently highlighted but selecting the 2nd or 3rd
option does nothing. It appears these options are highlighted because
the colour scheme I am using, which is forget-me-not thinks they are
push buttons.
Does anyone know why these don't work anymore in Fedora 23? I am using
Breeze for the Windows Style and Windows Decorations themes.
regards,
Steve

bad results from adding samsung v-nand SSD 950 PRO M.2 to ASUS
laptop
by Robert P. J. Day
yesterday, i popped open my ASUS G752VL-DH71 to see two available
slots for SSD drives, both clearly labelled "PCIE only", so i inserted
a new samsung 950 PRO in slot 1, closed it up and booted and
(reproducing from scribbling on some paper, just the first bit):
ata1.00: failed to enable AA (error_mask=0x4)
ata1.00: revalidation failed
etc, etc, at which point it finally dropped me into an emergency
shell.
i didn't have time to debug so i just removed it and got back to
work, but is there something i'm forgetting here? here's the samsung
page for that drive:
http://www.samsung.com/semiconductor/minisite/ssd/product/consumer/950pro...
thoughts? like i said, i did not invest a lot of time trying to track
this down as i have way too much to do, but if there's something
stupid i've done, it would be good to know.

Fedora 24 and PNY SSD Problems
by Gregory P. Ennis
Everyone,
I am trying to reclaim some use out of a couple old Compaq Presaio
SR1720NX machines for the office by adding some memory and a PNY 240 GB
CS1311 SSD drives. The bios was made by Phoenix; I did not identify a
version number of the bios. I did not plan on keep the hard drive
installed and planned on just using the SSD. These machines were IDE
machines and only had two SATA ports on the motherboard.
When I install the SSD the bios recognizes the Pny SSD properly, and I
was able to set up the boot order without difficulty.
When I tried to install Fedora 24 on the first machine the installation
software did not identify the presences of the SSD. I also tried a
Centso 7.2 install disc and the SSD was not recognized with it as well.
Just to make sure things were working, I added the hard drive back to
the machine, and the Fedora install routines did recognize the hard
drive but continued to fail to recognize the SSD.
Are there preparatory things that I need to do with the SSD drives that
I am missing? Any help would be appreciated.
Thanks,
Greg Ennis

Re: application to listen to on-line broadcasts? [SOLVED]
by William Mattison
Good morning,
I'm now thinking that for the long term, I'm probably better off waiting
for chromium to become available in Fedora. A concern is that wikipedia
implies that code for flash-like functionality is not included in
chromium. So for the short term, I'm back to flash.
I am almost certain that 2-3 years ago, I installed flash from the adobe
web site. But it never worked. A short while ago, I tried "dnf info
flash" to see if I have it, and if so, what version. I must be
mis-understanding the dnf man page. I got this:
bash.2[~]: dnf info flash
Fedora 23 - x86_64 3.5 MB/s | 43 MB
00:12
RPM Fusion for Fedora 23 - Free 511 kB/s | 457 kB

Last metadata expiration check: 0:00:07 ago on Wed Jul 27 09:31:01 2016.
Error: No matching Packages to list
bash.3[~]:
First, how do I determine whether or not I already have flash, and if
so, which version?
Second, If I don't already have flash, what's the best way to get the
right flash? And then what do I need to do so Firefox launches it when,
for example, I want to see a flash video in the yahoo finance web site?
(and then there's those National Weather Service RADAR loops!)
Third, what did "dnf info flash" actually do? Do I now have a bunch of
files that I should delete? If yes, where are they?
Thank-you for your help.
Bill.
(p.s. This is one of those rare cases where I wish I could change the
title or topic of this thread!)

gcc 4.9
by Amadeus W.M.
I want to do some parallel programming on my nvidia GPU, and for that I
need cuda. The latest is cuda 7.5 and that requires gcc 4.9. I installed
cuda on my machine, but little did I know that fedora 24, which I recently
installed, came with gcc 6.1. I wasn't able to compile any of the cuda
examples. I asked on the nvidia forums about this and the next cuda
(version 8.0) will require gcc-5.3 or so. No indication when cuda will
work with gcc-6.1.
So what do I do now? From some posts I read it appears that debian
provides a gcc49 package, and so I hoped fedora would provide one too, but
no such luck. Can I rebuild the gcc-4.9 rpm on F24 without messing up the
stock gcc-6.1? Or, can I convert the gcc49.deb package into the equivalent
rpm? I can try these things and try to be careful not to mess up, but I
was wondering if anyone had any experience with this or any suggestions.
Thanks!

systemd vs. autofs/nfs
by David A. De Graaf
systemd and autofs/nfs are at war and have been ever since systemd
appeared.
Specifically, if machine A has an open connection to machine B
and B goes down or become inaccessible, then A cannot shutdown.
A's shutdown sequence hangs, waiting for B to respond to an unmount
command, which will not/cannot happen.
WAITING WILL NOT HELP.
Only a dirty disconnect will work; there's no way to avoid it.
Here's what I've tried:
- Precede 'shutdown' or 'reboot' or 'systemctl reboot' with
umount -fl -t nfs <each nfs-mounted-filesystem>
(You might expect a forced lazy umount to do the job.
It doesn't work; umount just hangs)
- Change nfs mount option to 'soft' instead of 'hard'.
Edit /etc/nfsmount.conf to say:
Hard=False
Soft=True
(This did change the autofs/nfs mount option, but didn't improve
the tolerance for a dirty disconnect. Shutdown still hangs.)
- Reduce systemd's timeout values from 90 to 10 sec;
edit /etc/systemd/system.conf to say:
DefaultTimeoutStartSec=10s
DefaultTimeoutStopSec=10s
(During shutdown, systemd displays two times; the time it has waited
for an unmount event, and the time limit to wait. Incomprehensibly,
when the time limit is reached, it bumps it up and continues to wait.
Changing the default timeout values seems to accelerate this recycling,
but doesn't do anything for the actual time limit.)
- Change the nfs timeout from 600 (default) to 20 decisec to reduce
the time nfs waits for any response, including umount, before
declaring a timeout. Edit /etc/nfsmount.conf to say:
# Timeo=600
Timeo=20
(The option displayed by the mount command did change, but it did not
help the shutdown hangup.)
- That leaves ONLY TWO WAYS to shutdown machine A, both ugly:
SysReq R E I S U B - which forces a reboot NOW
Hold the Power button - which just stops everything.
This is NOT NEW. Systemd has had this design defect from day one.
SysV never hung on shutdown. It Just Knew when a dirty disconnect
was the only viable way and handled it.
How many more years must we wait?
Have I overlooked something obvious? Is there a way to make systemd
perform the simple function 'shutdown' smoothly, reliably and quickly?
If anyone knows how, I would love to hear it.

Date change on reboot
by Stephen Davies
My F22 randomly crashes to a frozen state that requires a power cycle to restart.
When this happens, the time stamp on log files such as /var/log/messages
changes for a while before reverting to the correct date and time.
Today,the sequence was:
Jul 24 10:55:55 mustang rsyslogd: [origin software="rsyslogd"
swVersion="8.8.0" x-pid="853" x-info="http://www.rsyslog.com"] start
Jul 15 11:19:20 mustang systemd: Stopped target Default.
Jul 15 11:19:25 mustang systemd: Stopping Default.
followed by some 17,000 lines with Jul 15 through to:
Jul 15 19:28:11 mustang named[1221]: client 122.61.143.143#39431 (isc.org):
query (cache) 'isc.org/ANY/IN' denied
Jul 24 10:56:14 mustang rsyslogd-2177: imjournal: begin to drop messages due
to rate-limiting
Sun Jul 24 10:56:16 ACST 2016 rc.fw
Jul 24 11:06:11 mustang rsyslogd-2177: imjournal: 2971956 messages lost due to
rate-limiting
A similar thing happens in /var/log/secure (though with fewer Jul 15 entries).
The Jul 15 dates have been appearing at/after the last two or three crashes.
Even though the Jul 15 entries look to span over eight hours, the actual time
span was only a minute or so.
Any suggestions as to what is happening here?
Cheers and thanks,
Stephen

Mobile Broadband connection in fc24
by Patrick Dupre
Hello,
I moved from fc22 to fc24.
I used to connect to a 3G mobile broadband connection by doing:
mcli -m 0 --pin=xxx -i /org/freedesktop/ModemManager1/SIM/0 --simple-connect="apn=3G"
then
systemctl stop NetworkManager
NetworkManager
and then
ma connection to the provider
