| 01:13 | <nrdb> I have googled for this... but I can't find an answer... I have a terminal is dual head (with one monitor) ... it appears the ltsp is spreading the login over both 'heads' ... this means the login is not centered on the one monitor it has.. can I tell the ltps to use only the one monitor, or turn off the other one.
| |
| 02:00 | could I use an X_OPTION_0 somehow to say turn this display off?
| |
| 02:43 | I have found that using ... X_MONITOR_OPTION_01 = "\"ignore\" \"true\"" ... turns off both displays ... is there anyway to get this just to be applied to one monitor?
| |
| 02:59 | how can the filesystem not have a xorg.conf file anywhere?

| 05:20 | <quinox> nrdb: I tell LTSP to use both monitors, showing the login box twice
| |
| 05:20 | X_VIRTUAL = "3840 1920"
| |
| 05:20 | XRANDR_OUTPUT_01 = "VGA-0 --auto"
| |
| 05:20 | XRANDR_OUTPUT_02 = "DVI-0 --auto --left-of VGA-0"
| |
| 05:21 | xrandr can also turn monitors off if that's what you want
| |
| 05:22 | 'VGA-0 --off'

| 07:25 | <muppis> What you use as default pdf viewer? Looks like there's a need for some extended features which aren't available in Evince.
| |
| 07:33 | * gehidore uses mupdf | |
| 07:34 | <gehidore> I suspect that's the opposite direction you're after though
| |
| 07:49 | <muppis> Not really. I'm all open to solutions if I can get things work.
| |
| 07:49 | Just made open in Chromium runned as local app.
| |
| 07:53 | Well, mupdf doesn't fulfill needs.

| 10:45 | <lauri> Hi, I am having UI glithces on Ubuntu 14.04 LTSP
| |
| 10:45 | It's x86 terminals with variety of hardware
| |
| 10:46 | Chromium draws the webpages with glithces
| |
| 10:46 | I am using thin clients
| |
| 10:46 | with LDM_DIRECTX
| |
| 10:46 | Is there anything I could tweak?

| |
| 11:58 | i have installed epoptes on edubuntu to act as a server and the clients are linux mint,i however cannot discover the client on the server

| 12:57 | <nahoskins> looking for a simple chat client for LAN chat with students
| |
| 12:57 | preferably with a way to limit based on ip add
| |
| 12:58 | so they chat to the teachers only
| |
| 13:03 | <maldridge> nahoskins: IRC?
| |
| 13:07 | <nahoskins> hey again
| |
| 13:07 | im using empathy at the moment
| |
| 13:07 | i was thinking of using irc
| |
| 13:07 | was hoping another teacher had come up with a simple apt-get away solutions
| |
| 13:10 | <maldridge> well there's plenty of simple web based ones, but I'm pretty sure that most on-disk ones will require configuration of some kind
| |
| 13:35 | nahoskins: depending on your students you could use talkd
| |
| 13:37 | <nahoskins> need names so i can use epoptes to remote in and assist
| |
| 13:38 | also will need microphone support...
| |
| 13:38 | would be better if it had webcam too!
| |
| 13:38 | <maldridge> talkd takes the username of the user, irc would take the username
| |
| 13:38 | oh, now you're getting fancy, not sure what the best way to do that is
| |
| 13:40 | <nahoskins> yeah
| |
| 13:40 | aim is to have them working on python notebooks
| |
| 13:40 | and as the more experienced kids level up
| |
| 13:40 | i promote them to "Tutor" accounts
| |
| 13:40 | with access to more tools/priviledges
| |
| 13:41 | so they can help/troubleshoot the others
| |
| 13:45 | my RAID server is pretty much set up, (im sure you remember that headache)
| |
| 13:46 | and I've managed to scrounge 20 half decent machines (2-4GB RAM)
| |
| 13:46 | only thing really killing it is the switch, need to upgrade that, got CAT 6 cables
| |
| 13:54 | ben_roose has joined IRC (ben_roose!~roose@roose.cs.wichita.edu) | |
| 14:00 | <maldridge> nahoskins: take a look at ubiquiti switches, they are generally pretty low cost
| |
| 14:00 | <nahoskins> cheers will do
| |
| 14:00 | wont be running codetuna till next spring i dont think
| |
| 14:01 | in last week of 6, looking forward to a break
| |
| 14:01 | will be writing a post on how various tech allows me to run camp
| |
| 14:01 | you'll probably get a mention on twitter when it goes up
| |
| 14:02 | camp wouldnt have worked without all the help from you and everyone else in this channel
| |
| 14:02 | <maldridge> ha, I'm just glad everything has worked. It sounds like you've had a rough time with some of it
| |
| 14:02 | <nahoskins> meh, nothing we couldnt handle!
| |
| 14:02 | once it was set up, it worked a treat all summer
| |
| 14:02 | now i just need to finesse the small details
| |
| 14:03 | and next summer ill have a lean mean learning machine
| |
| 14:03 | <maldridge> document!
| |
| 14:03 | <nahoskins> got a 7 year old handling arrays with for loops and double nested ifs in python
| |
| 14:03 | ;)
| |
| 14:03 | success!
| |
| 14:04 | <maldridge> that is indeed a feat, there are plenty of students at my university that seem to struggle with that for far longer than they should

| 15:20 | <nahoskins> had a 12 year old make a joke machine in 17 lines of python without any kind of prompting
| |
| 15:20 | very cool
| |
| 15:20 | its amazing what these kids are capable of
| |
| 15:20 | after three weeks of 4-5 hours of coding a day
| |
| 15:21 | nice plus side: I've gotten EXCEPTIONALLY good at identifying errors in my own code
| |
| 15:22 | now i have 45 minutes to trouble shoot an issue with minecraft mods, if i dont get that done i will be crucified. Must keep the reward schema in good stead.
| |
| 15:27 | <maldridge> ha, mods are a pain, good luck

| 21:22 | <gnimi> Cheers everyone. Just set up debian with ltsp; trying to connect with berryterminal; when I log in, I get a screen that shows this "Oh no! something has gone wrong" message; any advice?
| |
| 21:22 | ah forgot: client is berryterminal operated on raspberrypi2
| |
| 21:22 | <maldridge> gnimi: do you have installed a gui?
| |
| 21:23 | <gnimi> yeah the standard debian gui
| |
| 21:23 | <maldridge> (installed in the chroot)
| |
| 21:23 | so gnome3
| |
| 21:23 | <gnimi> I guess... haven't been using linux in a while
| |
| 21:24 | I installed the latest stable debian release (amd64 version)
| |
| 21:24 | And just used the preselected settings in the graphical installer, which was that "debian ui" or something
| |
| 21:25 | <maldridge> hrm, I'm not particularly familiar with that error (haven't used gnome in a while) but generally it means that gnome couldn't start for various gfx issues
| |
| 21:25 | <gnimi> yeah, sounded like that... at least that's what google gave me
| |
| 21:25 | <maldridge> you might need to install something lighter, the pi can only do so much
| |
| 21:25 | <gnimi> But that should be client side only, right? since all of the graphics should be handled on the client for ltsp, right?
| |
| 21:25 | Ah, yeah... good idea, maybe that's it
| |
| 21:26 | <maldridge> well, the drawing should happen client side, but the program runs server side
| |
| 21:27 | <gnimi> yep, then I understood it correctly
| |
| 21:27 | thanks so far. I will have a look whether there is a better suited ui for the raspi
| |
| 21:27 | regards from our makerspace here in Germany :-)
| |
| 21:29 | <maldridge> cool, you should add a pin to the pinboard when you get your install up
| |
| 21:31 | <gnimi> Sure, will do. :-)
| |
| 21:37 | turns out you were right
| |
| 21:38 | When i select in the client under the sessions menu: failsafe xterm
| |
| 21:38 | then it works
| |
| 21:39 | but whenever I select gnome or gnome classic, it stops with that oh no error message
| |
| 21:43 | <maldridge> huh, gnome likes to really have high levels of hardware acceleration. You might look into lxde or xfce4, they are low overhead
