| 01:03 | SW Harbor, Maine
| |
| 01:03 | gonna join us?
| |
| 01:03 | <warren> oh
| |
| 01:03 | I live a little far from there now
| |
| 01:03 | <jammcq> well... far is a relative thing
| |
| 01:03 | <warren> I used to be able to drive there.
| |
| 01:03 | now I can't drive there
| |
| 01:04 | I was so proud of myself when I drove the second time to/back without a GPS or map.
| |
| 01:04 | <jammcq> heh
| |
| 01:04 | <warren> Only got 20 miles lost.
| |
| 01:06 | jammcq: is our hackjob of stringing ethernet still working for him?
| |
| 01:06 | what was his name... david?
| |
| 01:06 | <jammcq> yeah, I think it's all working well
| |
| 01:06 | yes, David Lloyd
| |
| 01:06 | <warren> Since then the Ubiquiti bridges came out, and I'd use that instead of wiring these days.

| 17:36 | <markit> hi ppl :) hi alkisg, when using ubuntu and gnome-fallback, do you use nfs or sshfs homes in recent installations? with KDE I'm forced with nfs + async, but don't remember what you suggest for other DE
| |
| 17:36 | <alkisg> Hi markit
| |
| 17:36 | NFS is better, SSHFS doesn't require setup
| |
| 17:36 | <markit> I vaguely remember mixed pros and cons, and don't remember if FOLLOW_SYMLINK stuff
| |
| 17:36 | alkisg: but both are working fine?
| |
| 17:37 | <alkisg> So we've been trying SSHFS in 12.04 as it is the LTSP default
| |
| 17:37 | Yes it appears to work OK, although of course if you're planning on doing fat clients + a lot of video prosessing, then you might want NFS to lower cpu usage..
| |
| 17:38 | <markit> not the case :)
| |
| 17:38 | I'm helping a friend in a far school, but in this school has a lot of trubles with video card (I suppose) of clients
| |
| 17:38 | geforce 7020 or something like that
| |
| 17:39 | not being an expert, he changes unrelated config making the system a mess :(
| |
| 17:39 | I'm reinstalling from scratch through ssh right now
| |
| 17:41 | he had "failed to load gnome-fallback"
| |
| 17:42 | even if the package was installed and lts.conf properly configured, with other client worked fine
| |
| 17:47 | <alkisg> 12.04 automatically installs the nvidia drivers if the server has nvidia
| |
| 17:47 | That then might cause problems on the clients
| |
| 17:56 | <markit> AH
| |
| 17:56 | alkisg: so was not using nv by default, but nvidia?
| |
| 17:56 | I told him then to install the proprietary drivers to try to solve
| |
| 17:57 | <alkisg> markit: you were talking about the client and me about the server
| |
| 17:57 | <markit> but, following what you say, they were already there
| |
| 17:57 | <alkisg> So unless he's using ltsp-pnp, those are different things
| |
| 17:57 | But, server-side drivers can cause problems to thin clients
| |
| 17:57 | But not to fat clients
| |
| 17:57 | ....need more details...
| |
| 17:57 | <markit> "server-side drivers can cause problems to thin clients" shocks me
| |
| 17:58 | <alkisg> Xorg has two components, a server and a client
| |
| 17:58 | <markit> yep
| |
| 17:58 | <alkisg> The proprietary nvidia drivers on the server misbehave
| |
| 17:58 | <markit> and server is the one that "talks" with the video boards
| |
| 17:59 | (thin or fat, in any case the client runs the X-server)
| |
| 17:59 | <alkisg> Yes, but on thin clients the ltsp server runs the xorg client, and that has nvidia gl libraries which misbehave and might even show the screen upside down or mirrored left/right
| |
| 18:01 | <markit> "on thin clients the ltsp server runs the xorg client" ? can't understand it
| |
| 18:01 | I thought was in any case running X-org server
| |
| 18:01 | (that talks with local video card)
| |
| 18:01 | (and does the rendering of the image)
| |
| 18:01 | ok ok
| |
| 18:01 | I misunderstood you
| |
| 18:01 | "ltsp server runs the xorg client" correct
| |
| 18:02 | <alkisg> https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/441586
| |
| 18:02 | <markit> and the xorg client is related with the video driver? strange, but I take note in case I will see that behaviour
| |
| 18:04 | alkisg: btw, on the server of my school, I replaced nvidia board with a radeon one and works fine now even with movies
| |
| 18:04 | Enslaver has joined IRC (Enslaver!~Enslaver@c-98-196-42-169.hsd1.tx.comcast.net) | |
| 18:04 | <markit> when I installed 11.04, was the contrary, lol
| |
| 18:05 | (radeon board had problems)
| |
| 18:05 | is a minefield :(
| |
| 18:05 | <alkisg> All are... except for most intels, plus the nvidia proprietary
| |
| 18:06 | Let's see if android/MIR will do better wrt drivers
| |
| 18:06 | <markit> some months ago we were discussing about Wayland and ltsp future
| |
| 18:06 | now Mir...
| |
| 18:06 | <alkisg> :)
| |
| 18:07 | <markit> looks the "hurt yourself" saga going on
| |
| 18:07 | <alkisg> And some time Qt future looks lame
| |
| 18:07 | ...and now it's on the frontpage again
| |
| 18:07 | <markit> and other bright
| |
| 18:07 | yep
| |
| 18:07 | the only rule I've learn so far is
| |
| 18:07 | <alkisg> On the other hand, windows programs that I've written 20 years ago, still run fine on windows 7
| |
| 18:07 | <markit> that wichever technology I choose is going to die ;P
| |
| 18:08 | alkisg: windows 8 is here to change that too ;P
| |
| 18:08 | <alkisg> Nah.. I doubt that
| |
| 18:08 | <markit> the cloud will obsolete us all
| |
| 18:08 | I've to find a more lasting job I guess
| |
| 18:08 | <alkisg> The cloud is too far away from here
| |
| 18:09 | Here we still have much sun, no clouds around :P
| |
| 18:09 | <markit> hehe
| |
| 18:09 | looks like digital photography... all the "old" related job were killed
| |
| 18:09 | <alkisg> Do you think that the italian ministry of education is going to pay amazon, canonical or whatever else, for cloud processing any time soon?
| |
| 18:10 | <markit> well, at the moment they are paying M$
| |
| 18:10 | usually ministry of education know nothing
| |
| 18:10 | just feel the smell of M$ money
| |
| 18:10 | <alkisg> They're buying academic licenses for all schools globally?
| |
| 18:10 | <markit> no, too cheap
| |
| 18:10 | it's done school by school
| |
| 18:10 | with central programs (from ministry)
| |
| 18:11 | that work ONLY with recent M$Office
| |
| 18:11 | or need M$ 2003 SERVER to run in school offices
| |
| 18:11 | and books with cdroms that run only on M$
| |
| 18:11 | and so on
| |
| 18:11 | next move... digital books
| |
| 18:12 | <alkisg> People behind ministry offices can understand cdroms and os licenses etc.. I don't think they'll be willing to accept "cloud services" soon...
| |
| 18:12 | <markit> but for sure with drm and ... you guess? iSomething chained
| |
| 18:12 | hehe, in a region in italy the politician first announced they support Free SOftware
| |
| 18:13 | then made a dael with M$ for moving the IT to Azure platform
| |
| 18:13 | of the public offices of that region
| |
| 18:13 | you figure :(
| |
| 18:13 | Configurazione di epoptes-client (0.5.6-1~precise1)...
| |
| 18:13 | update-rc.d: warning: epoptes-client stop runlevel arguments (0 1 6) do not match LSB Default-Stop values (none)
| |
| 18:13 | is it ok?
| |
| 18:13 | <alkisg> They had a deal with MS here too, for buying cheap products. But after the deal they didn't actually buy the products...
| |
| 18:13 | Yes it's o
| |
| 18:13 | <markit> (I've seen it before, and epoptes works fine)
| |
| 18:14 | <alkisg> ok
| |
| 18:14 | <markit> Phantomas: another task for you ;P
| |
| 18:15 | <alkisg> No, it's an ubuntu problem
| |
| 18:15 | <markit> "Parallel mksquashfs: Using 24 processors"
| |
| 18:15 | they have bought a SUPER server, incredible waste of money
| |
| 18:16 | 64GB ram
| |
| 18:16 | <alkisg> Most packages that have initscripts report that mismatch
| |
| 18:16 | Wow... perfect for thin clients
| |
| 18:16 | <markit> biprocessor...
| |
| 18:16 | yep, 24 clients
| |
| 18:16 | but they will go for fat
| |
| 18:16 | the same model of server in the previous school had problems with ubuntu 32 bit
| |
| 18:17 | but worked fine with the 64 bit version
| |
| 18:17 | is a biprocessor
| |
| 18:17 | dell something
| |
| 18:17 | Intel(R) Xeon(R) CPU E5645 @ 2.40GHz
| |
| 18:18 | do you think instaling linux-image-generic-lts-quantal in chroot could help?
| |

| 22:20 | <kev_j> what's the usage for xrandr_output_#? Would I put the display (i.e. DVI-0) or an xrandr command?
| |
| 22:21 | or something altogether different?
| |
| 22:32 | so from what I can tell I'm supposed to put the xrandr variables.. but I don't quite understand... Do I still need to put the "xrandr --output blah --mode blah" and if so how does xrandr_output_0 differ from xrandr_command_0?
| |
| 22:33 | <vagrantc> i think it's essentially "xrandr --output $XRANDR_OUTPUT_0"
| |
| 22:34 | kev_j: xrandr_command_0, if you know what you're, is more flexible
| |

| 22:38 | vagrantc: if I can't get it to work using xrandr in shell it prolly wouldn't magically work differently by issuing the command through lts.conf? (still having some issues I was asking you about before concerning dual head setup)

| 22:43 | <kev_j> Not that I am asking you to answer something you already told me you don't know... just asking if you think the xrandr_command or xrandr_output would act differently just because I put it in the lts.conf instead of running the same command in the shell
