Alternatives to Theme Font size changer Firefox plugin?
by Sam Varshavchik 28 Oct '16

28 Oct '16

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 10 Oct '16

10 Oct '16

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 16 Aug '16

16 Aug '16

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.h… 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. rday -- ======================================================================== Robert P.

Fedora 24 and PNY SSD Problems
by Gregory P. Ennis 06 Aug '16

06 Aug '16

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 04 Aug '16

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 00:00 RPM Fusion for Fedora 23 - Nonfree - Updates 207 kB/s | 54 kB 00:00 RPM Fusion for Fedora 23 - Free - Updates 350 kB/s | 160 kB 00:00 RPM Fusion for Fedora 23 - Nonfree 336 kB/s | 156 kB 00:00 Fedora 23 - x86_64 - Updates 7.6 MB/s | 24 MB 00:03 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. 02 Aug '16

02 Aug '16

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 02 Aug '16

02 Aug '16

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. -- David A. De Graaf DATIX, Inc. Hendersonville, NC dad(a)datix.us www.datix.us "Tolerance becomes a crime when applied to evil." -- Thomas Mann

Date change on reboot
by Stephen Davies 01 Aug '16

01 Aug '16

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 31 Jul '16

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 Unfortunately, after I moved to fc24, this does not work: I get connection fails, Activation: failed for connection, here is a part of /var/log/messages: Jul 31 12:48:27 sophocle NetworkManager[3863]: <info> (ttyUSB4): device state change: config -> ip-config (reason 'none') [50 70 0] Jul 31 12:48:27 sophocle NetworkManager[3863]: <warn> (ttyUSB4): interface ttyUSB4 not up for IP configuration Jul 31 12:48:27 sophocle NetworkManager[3863]: <info> (ttyUSB4): using modem-specified IP timeout: 20 seconds Jul 31 12:48:27 sophocle NetworkManager[3863]: <error> [1469962107.287907] [NetworkManagerUtils.c:352] nm_utils_modprobe(): modprobe: '/sbin/modprobe ppp_generic' exited with error 256 (modprobe: FATAL: Module ppp_generic not found in directory /lib/modules/4.4.13-200.fc22.i686) Jul 31 12:48:27 sophocle NetworkManager[3863]: <info> starting PPP connection Jul 31 12:48:27 sophocle NetworkManager[3863]: <info> pppd started with pid 5020 Jul 31 12:48:27 sophocle pppd[5020]: Plugin /usr/lib/pppd/2.4.7/nm-pppd-plugin.so loaded.
