CentOS 7 + KDE: Okular view PDF files OK but prints a blank page
by Nicolas Kovacs 01 Jun '17

01 Jun '17

Hi, I recently installed CentOS 7 + KDE 4.14 on my main workstation, and overall I'm very happy with it. Okular seems to have trouble with some PDF files. I'm using the Dolibarr application to generate invoices. I can view the resulting PDF file OK, but when I try to print it, I get a blank page. A few days ago I had a similar problem with a PDF file generated from a french administration online form. On my previous installation (Slackware64 14.1 + Xfce + Evince built from source) I never had any trouble with PDF files. Any suggestions?

Re: [CentOS] GPX files

Thanks for the suggestions. I'd seen gpsbabel, but simply converting the tracks doesn't appear to display them. Another user suggested a downloadable Google Earth, so I'll try that. Failing all else, I've used shell scripting in my day job for the last 18 years (and before that Digital's DCL for the previous 18 years). I'm just trying to avoid reinventing the wheel. Once again, thanks all for the suggestions.

CentOS 7, X issue
by m.roth＠5-cent.us 31 May '17

31 May '17

One of my users is reporting that he's working (heavy graphics, I believe), and X freezes. So, to save him from rebooting, I did init 3. And waited. Almost a minute and a half later, it had not completed. I quit, killed X, and then could init 3, then init 5. I'm not finding clues as to what hung. In messages, I see ay 31 12:07:14 <workstation name> gnome-session: (tracker-miner-fs:1931): GLib-GObject-WARNING **: g_object_notify: object class 'UpDevice' has no property named 'g-name-owner' May 31 12:08:28 <workstation name> abrt-hook-ccpp: Process 31430 (Xorg) of user 0 killed by SIGABRT - dumping core May 31 12:08:29 <workstation name> gnome-session: (gnome-settings-daemon:1677): Gdk-WARNING **: gnome-settings-daemon: Fatal IO error 11 (Resource temporarily unavailable) on X server :0. The abrt is, I believe, when I killed X. I can't find anything googling, anyone got any thoughts on this? 7.3.1611. Looking at yum.log, I see the cron job updated glibc, dracut, and systemd a few days after I fully updated and rebooted it. mark

Mini PCs
by Robert Moskowitz 31 May '17

31 May '17

I have been working, for the past few years, with armv7 SOCs and have a number of servers working. Intel, etal are catching up with ARM and I have seen ones like: https://www.aliexpress.com/item/NEW-Mini-pc-X86-4-Lan-Qotom-Q190G4N-with-ce… I am looking for a low power (this is 10W) x86_64 board that has at least 2 core and 2GB memory. A single LAN port, a few USB and sata (not mSata) that supports a 1TB drive (2.5", 5V is just fine). Oh, and for ~$100 :) Case is not necessary, as I can put it in my rack like these: http://medon.htt-consult.com/~rgm/cubieboard/cubietower-3.JPG (goal is to replace that SFF to the left). It looks like Qotom might have one. It is a bit challenging to figure out which units have what. thanks for any pointers.

IPv6 addresses order (CentOS6)
by Walter H. 31 May '17

31 May '17

Hello, in /etc/sysconfig/network-scripts/ifcfg-eth0 I have this <ifcfg-eth0> ... IPV6INIT=yes IPV6ADDR=prefix::5 IPV6ADDR_SECONDARIES="prefix::2 prefix::3 prefix::4" IPV6_AUTOCONF=no IPV6_DEFAULTGW=prefix::1 IPV6_DEFAULTDEV=eth0 </ifcfg-eth0> when I enter ifconfig the IPv6 addresses are in a different order <ifconfig> eth0 Link encap:Ethernet HWaddr ... inet addr:... Bcast:... Mask:... inet6 addr: fe80::.../64 Scope:Link inet6 addr: prefix::4/64 Scope:Global inet6 addr: prefix::3/64 Scope:Global inet6 addr: prefix::5/64 Scope:Global inet6 addr: prefix::2/64 Scope:Global </ifconfig> is there a way to influence the order? or how can I tell e.g. ssh to use a specific IPv6 address? (as it seems ssh uses the first one listed in ifconfig and not the one defined with IPV6ADDR) Thanks, Walter
