12:07 PM kwallace2: OT but interesting: http://www.daliborfarny.com/ https://www.youtube.com/user/daliborfarny/videos
04:18 PM KGB-linuxcnc: 03Jeff Epler 05master 4290ecf 06linuxcnc Merge branch 'master' of https://github.com/rene-dev/linuxcnc * 14http://git.linuxcnc.org/?p=linuxcnc.git;a=commitdiff;h=4290ecf
04:24 PM mozmck: pcw_home: you said you have crashes with any 4.x kernel on older intel graphics systems. Have you compared your config to one for similar hardware at osadl.org?
04:42 PM pcw_mesa: mozmck: I think I've tried every suggested I915 workaround and some older (Core Duo vintage) intel graphics systems
04:42 PM pcw_mesa: simply wont run reliably with 4.X kernels. They may run for a week or so but eventually crash
04:42 PM pcw_mesa: on 3.18 they runs for months on end
04:43 PM mozmck: pcw_home: interesting. I was just looking through the data on osadl and wondered.
04:44 PM mozmck: I'm running 3.18, and mostly on J1800/J1900 and core2-duo cpus
04:45 PM pcw_mesa: not an issue with newer MBs (I3/I5/I7,G32XX,J1800,1900,N31XX etc)
04:45 PM mozmck: I'm having some issues with the J1800 boxes sometimes getting really sluggish, and when they do the latency is also bad.
04:46 PM mozmck: It seems random, and I'm not sure what to look for.
04:46 PM pcw_mesa: does top show anything?
04:47 PM mozmck: I have only had it happen once on my test machine and that was today. Top seemed to show irq/92_i915 close to the top more often than it does when not in the sluggish mode.
04:47 PM mozmck: Possibly also irq/something-related-to-audio
04:50 PM pcw_mesa: do you have video power management disabled?
04:50 PM mozmck: Hmm, in the OS or kernel?
04:51 PM pcw_mesa: kernel (I know that video power management can trigger a crash on some J1XXX, N31XX systems)
04:52 PM mozmck: I disabled the power management stuff when I built the kernel, but if there was a separate section for video power then probably not.
04:55 PM pcw_mesa: I have it disabled in the kernel command line:
04:55 PM pcw_mesa: i915rc6 = 0
04:56 PM seb_kuzminsky: 2.9.10 is imminent, what outstanding issues have i forgotten?
04:57 PM mozmck: pcw_home: thanks - I'll try that. One problem is that it is so intermittent it is hard to test because it will never do this when you want it to.
04:59 PM pcw_mesa: yeah thats like the older Core Duo MBs with 4.XX kernels, they may run a week or so just fine and then trip on their shoelaces
05:00 PM pcw_mesa: 2.7.10? or have I skipped forward a year or so...
05:02 PM mozmck: I think seb is talking about linuxcnc ;-)
05:05 PM seb_kuzminsky: oh yeah, that :-)
05:17 PM jepler: seb_kuzminsky: https://github.com/LinuxCNC/linuxcnc/issues?q=is%3Aopen+is%3Aissue+label%3A%22affects+2.7%22 hmm I actually had a patch for https://github.com/LinuxCNC/linuxcnc/issues/273 ...
05:17 PM jepler: seb_kuzminsky: maybe consider pulling https://github.com/LinuxCNC/linuxcnc/pull/299 to cloes #273
05:18 PM jepler: and bumping the version to 2.9.10 has my approval
05:20 PM seb_kuzminsky: oh yeah, the gstreamer thing
05:20 PM seb_kuzminsky: i talked with norbert about it, he said he thought he had a fix for it, but then said the fix didnt work, and i haven't heard from him for several days
05:24 PM jepler: the base gscreen/gmoccapy come up just fine on the live image fwiw
05:24 PM jepler: so it's just extended functionality, and I suspect it's a distinct minority who are enabling it
05:31 PM seb_kuzminsky: yeah, it's just for playing warning beeps in some situations, apparently
05:33 PM seb_kuzminsky: i'm no multimedia guy, but it seems like that should be possible with lightweight tools
05:47 PM jepler: idk
05:55 PM seb_kuzminsky: i found an old script that uses alsaplayer, from alsaplayer-text.deb, to play mp3s and ogg files and stuff
05:55 PM seb_kuzminsky: it interacts nicely with existing audio streams
05:55 PM seb_kuzminsky: Installed-Size: 41
05:56 PM seb_kuzminsky: no dependencies beyond standard system libraries
05:58 PM seb_kuzminsky: but it doesn't know how to play the .oga files that gmoccapy wants to play
05:59 PM seb_kuzminsky: which is weird, it's standard ogg vorbis
06:09 PM cradek: I wonder if people who are not me would know to install task-print-server in order to add a printer, or if there's a guiish way I don't know about that they would be likely to find
06:11 PM jepler: oh is that missing from the new .iso image?
06:11 PM jepler: I can add it, "how much space can it possibly take?"
06:12 PM cradek: 0 upgraded, 79 newly installed, 0 to remove and 0 not upgraded.
06:12 PM cradek: Need to get 32.6 MB of archives.
06:12 PM cradek: After this operation, 86.0 MB of additional disk space will be used.
06:12 PM cradek: not much in a squashfs I bet
06:12 PM cradek: I don't know how many people will need it. surely some...
06:13 PM jepler: [while task-print-server is not installed] if you try to "troubleshoot" from within "print settings", it directs you to look in a menu item that doesn't exist
06:13 PM cradek: siiigh
06:14 PM cradek: and when I printed something it immediately requested A4 paper
06:14 PM jepler: well that's just how the world works
06:14 PM jepler: I can turd up /etc/pagesize as a big middle finger to all the other countries in the world
06:15 PM jepler: or whatever the magic file is
06:15 PM cradek: papersize
06:15 PM cradek: which still says a4... wonder how people would know to edit that
06:15 PM seb_kuzminsky: you'd think it'd be able to guess, like it guesses timezone and keyboard layout
06:15 PM cradek: weirdly I don't have $TZ in my environment, but date does show CDT
06:16 PM seb_kuzminsky: well, see y'all, i'm off to cook burgers for my kids & parents
06:16 PM jepler: $ cat /etc/timezone
06:16 PM jepler: America/Chicago
06:16 PM jepler: see ya seb_kuzminsky
06:16 PM cradek: huh I got US/Central
06:16 PM cradek: seb_kuzminsky: enjoy!
06:16 PM jepler: "Etc/UTC" booted live :-P
06:28 PM Tom_itx: i noticed it didn't default to US English either
07:02 PM jepler: weird, that it does here
07:02 PM jepler: 'echo $LANG' prints en_US.UTF-8
07:02 PM Tom_itx: that last iso i tested didn't
07:02 PM Tom_itx: not a big deal, it just used to...
07:02 PM jepler: what language did it give you?
07:02 PM Tom_itx: iirc it started at the top of the list
07:04 PM jepler: if you choose the item "Debian Live with Localisation(sic) support", the next step is an alphabetical list of languages. But if you choose the top item, "Debian GNU/Linux Live..." it should give you US English by default
07:05 PM Tom_itx: i can check it later
07:32 PM Tom_itx: the live cd option just booted right into linux, didn't ask anything
07:33 PM Tom_itx is now known as Tom_L
