| 12:01 | <Allahu> uhm, hello?
| |
| 12:05 | I have installed ltsp on my terminalserver, and i have succesfully connected with some cloned VMs. When i create a fresh VM i does not find the DHCP, so i don't have any IP. Ii automatically starts the pxe at boot, i put static DHCP and get the error message no boot filename
| |
| 12:12 | gbaman has joined IRC (gbaman!~gbaman@host81-148-184-31.in-addr.btopenworld.com) | |
| 12:28 | <Hyperbyte> Allahu, sounds like a problem with your VM software, not LTSP
| |
| 12:30 | <Allahu> What does it mean, no boot filename? I thought it can't find the boot file, because of no connection to DHCP.
| |
| 12:30 | I just want to make sure that i don't have to download some sort of boot file.
| |
| 12:36 | <Hyperbyte> Not sure, it could indicate that your VM received a dhcp reply (IP address) without TFTP details, such as, where to find it's boot file.
| |
| 12:37 | <Allahu> Does the DHCP and LTSP has to be on same server for this?
| |
| 12:37 | <Hyperbyte> No
| |
| 12:38 | Do you have a DHCP server running on the VM client perhaps?
| |
| 12:38 | <Allahu> No, that's on a different one
| |
| 12:40 | I have been talking to Akhbar, we're going to set up DHCP and DNS on the terminal (standalone version), maybe that will fix potential wrong IP configurations
| |
| 12:40 | <elias_a> Is this some sort of a joke?
| |
| 12:41 | <Allahu> I am just having fun with aliases, elias_a, kinda boring
| |
| 12:42 | * Hyperbyte is confused | |
| 12:43 | <Allahu> Appreciate the productive support though :)
| |
| 12:49 | <elias_a> Allahu: Well, to be honest your playing with words distracted me totally. On the other hand I am a trained religion teacher. :P

| 14:12 | <bennabiy> I have an issue where my clients are booting, but losing their display once ldm kicks in
| |
| 14:13 | I can see the clients in epoptes, and if I blindly type in my credentials, I can log in to it and such, but with no display
| |
| 14:13 | it acts like it is out of range, but the display does not indicate that
| |
| 14:16 | hmm, tough crowd these days.

| 19:00 | * vagrantc waves | |
| 19:01 | <alkisg> bennabiy: ubuntu? which version?
| |
| 19:01 | What kernel?
| |
| 19:01 | uname -a
| |
| 19:01 | and which xorg version
| |
| 19:01 | * vagrantc waves to alkisg | |
| 19:01 | <bennabiy> 14.04
| |
| 19:01 | <alkisg> Hi vagrantc!
| |
| 19:01 | <bennabiy> well, mint 17.1 which is based on 14.04
| |
| 19:02 | 3.13.0-49-generic
| |
| 19:03 | <alkisg> Do you have some splitter inbetween?
| |
| 19:03 | <bennabiy> nope
| |
| 19:03 | display port connection
| |
| 19:04 | but it is happening to all clients
| |
| 19:04 | (all = 2)
| |
| 19:04 | both the same kind of client, and both have the same kind of monitor (which was just working before I upgraded the system from 13.04 to 14.04)
| |
| 19:06 | <alkisg> Is e.g. mint working there if you use a live usb stick ?
| |
| 19:09 | <bennabiy> I guess I could try a live stick on the machine... I know personally that mint17 works fine with these clients (having 2 other labs both running them)
| |
| 19:19 | bah, forgot these thin clients are only 32 bit.
| |
| 19:22 | the clients show the screen, show the nbd negotiation then the screen flickers and goes black
| |
| 19:22 | but the monitor never indicated that it lost signal
| |
| 19:26 | <alkisg> I can't see how ltsp would affect the (not) detected monitors
| |
| 19:26 | Assuming that you don't pass anything like nomodeset in the command line,
| |
| 19:26 | or other things in lts.conf about xorg
| |
| 19:26 | /var/log/Xorg.7.log.old from the client might help
| |
| 19:34 | <bennabiy> let me see what it says...
| |
| 19:35 | booting client back up again
| |
| 19:41 | https://pastebin.mozilla.org/8829651
| |
| 19:42 | that is the Xorg.7.log
| |
| 19:46 | <alkisg> bennabiy: you have this in cmdline: video=LVDS-1:d
| |
| 19:46 | Try removing it
| |
| 19:47 | <bennabiy> It was doing the same thing before I added it
| |
| 19:47 | <alkisg> Also, what are the contents of "/var/run/ltsp-xorg.conf" on the client?
| |
| 19:49 | <bennabiy> https://pastebin.mozilla.org/8829652
| |
| 19:50 | alkisg ^
| |
| 19:52 | <alkisg> bennabiy: and the output of `getltscfg -a` ?
| |
| 19:55 | <bennabiy> https://pastebin.mozilla.org/8829655
| |
| 19:56 | <alkisg> Try without video= in the cmdline, and without an lts.conf
| |
| 19:57 | I don't think an ltsp-xorg.conf should be generated in your case
| |
| 19:59 | <bennabiy> rebooting
| |
| 20:00 | same thing without video= and lts.conf
| |
| 20:00 | <alkisg> You still have an ltsp-xorg.conf? Do you have some custom script that generates it?
| |
| 20:01 | And getltscfg -a now is empty?
| |
| 20:02 | <bennabiy> still a ltsp-xorg.conf and an empty getltscfg -a output
| |
| 20:02 | <vagrantc> ltsp-xorg.conf will get generated with any setting that gets triggered
| |
| 20:02 | <bennabiy> nothing custom generating the ltsp-xorg
| |
| 20:03 | <vagrantc> "getltscfg -a" can be a bit misleading with all the ltsp_config.d hooks
| |
| 20:03 | <alkisg> vagrantc: with an empty lts.conf, why would a xorg.conf be generated?
| |
| 20:04 | bennabiy: can you try with CONFIGURE_X=False?
| |
| 20:05 | Although that may get automatically overriden...
| |
| 20:05 | <bennabiy> so do you want me to add that to lts.conf?
| |
| 20:06 | or build a client with that?
| |
| 20:06 | <alkisg> bennabiy: hmm let's see if we can find another way to prohibit xorg.conf generation
| |
| 20:07 | Currently, `ps` shows xorg -config, right?
| |
| 20:07 | xorg -config /var/run/ltsp-xorg.conf...
| |
| 20:07 | <bennabiy> let me check
| |
| 20:08 | <alkisg> Try INIT_COMMAND_1="rm /usr/share/ltsp/screen-session.d/XS90-set-x-conf"
| |
| 20:08 | In lts.conf
| |
| 20:08 | To completely delete the script that passes that -config in xorg
| |
| 20:08 | If it works that way, we can later start searching why a xorg.conf is generated...
| |
| 20:10 | <bennabiy> booting
| |
| 20:12 | nope
| |
| 20:12 | blank
| |
| 20:13 | <alkisg> And now X doesn't have a -config option, right?
| |
| 20:13 | What's xorg.7.log like now?
| |
| 20:13 | You can also just try SCREEN_02=shell (without 07=ldm), and run X -configure there, or `xinit xterm`
| |
| 20:16 | <bennabiy> X does not have a config... coming up Xorg.7.log
| |
| 20:16 | https://pastebin.mozilla.org/8829660
| |
| 20:18 | <alkisg> bennabiy: it doesn't complain about missing devices now
| |
| 20:18 | What's the output of `xrandr` from epoptes now?
| |
| 20:18 | Does it list modes?
| |
| 20:20 | <bennabiy> https://pastebin.mozilla.org/8829661
| |
| 20:22 | <alkisg> Well, that was a bit of progress... is LVDS the normal output for the displaymode connection?
| |
| 20:22 | <bennabiy> No
| |
| 20:22 | LVDS is a phantom display, which the video=LVDS-1:d fixes
| |
| 20:22 | <alkisg> And the normal output is what, DP1?
| |
| 20:23 | <bennabiy> I think so.
| |
| 20:23 | Yes
| |
| 20:23 | DisplayPort
| |
| 20:23 | <alkisg> The phantom display shouldn't affect the existing display though
| |
| 20:23 | Could you try with a live usb stick?
| |
| 20:23 | <bennabiy> Well, it causes it to think it has two monitors hooked up
| |
| 20:23 | <alkisg> Of the same version?
| |
| 20:24 | Yes, you should get 2 lists in xrandr then, not 1
| |
| 20:24 | If you did get a list for DP, then ok you could fix it with LVDS-1=off
| |
| 20:24 | <bennabiy> yes
| |
| 20:24 | <alkisg> Try with a mint 17 usb stick
| |
| 20:24 | Check xrandr there, xorg.log etc
| |
| 20:24 | And compare with X -configure in an ltsp netbooted client
| |
| 20:25 | Normally there shouldn't be any differences
| |
| 20:25 | <bennabiy> I think I need to keep working on this after the weekend. I am running out of time.
| |
| 20:25 | <alkisg> I don't think what you're seeing is caused by something in upstream ltsp
| |
| 20:25 | <bennabiy> I will try to make a 32 bit stick
| |
| 20:25 | <alkisg> Good luck!
| |
| 20:25 | <bennabiy> thank you
| |
| 20:28 | <vagrantc> alkisg: because there are other hacks that set variables.
| |
| 20:28 | <alkisg> vagrantc: we have hacks that can generate a xorg.conf with an empty lts.conf?
| |
| 20:29 | <vagrantc> screen-session.d
| |
| 20:29 | <alkisg> Which one?
| |
| 20:30 | <vagrantc> XS20-intel-virtual-hack
| |
| 20:31 | other of the XS20*
| |
| 20:31 | <alkisg> No VIRTUAL there though: https://pastebin.mozilla.org/8829652
| |
| 20:32 | That was the auto-generated ltsp-xorg.conf
| |
| 20:32 | <vagrantc> ah.
| |
| 20:32 | * alkisg checks why that hack exists, though... | |
| 20:32 | <vagrantc> it's a gadi thing.
| |
| 20:33 | <alkisg> OK I see why it didn't do anything for bennabiy
| |
| 20:33 | <vagrantc> something to do with some systems having a vga + dvi output as separate devices, but only one is actually physically connected
| |
| 20:33 | <alkisg> I think you're correct in that that is what generated a xorg.conf
| |
| 20:34 | bennabiy doesn't have an XRANDR_MODE* defined, so no virtual for him
| |
| 20:34 | * vagrantc thinks one of those hacks is a likely suspect | |
| 20:34 | <alkisg> Ah, I got what Gadi is trying to do there
| |
| 20:34 | To add all the widths of all the monitors, to calculate the virtual width
| |
| 20:35 | E.g. if you have 1024*768 + 1280x800, side by side, then you need virtual=(1024+1280, 800)
| |
| 20:37 | bennabiy is now known as bennabiy_away | |
| 20:39 | <vagrantc> something like that
| |
| 20:39 | <alkisg> vagrantc: XS20-xserver-geode-gx2-hack forces XAA, which was dropped 3 years ago...
| |
| 20:39 | Maybe we need to review those hacks?
| |
| 20:46 | bennabiy_away is now known as bennabiy | |
| 20:47 | <bennabiy> livecd does the same thing...
| |
| 20:48 | and so does leaving SCREEN_07=ldm out
| |
| 20:49 | well, I will be back tomorrow night or Sunday
| |
| 20:50 | Thanks for all the help so far...
| |
| 20:50 | It is nice to talk with you both again after so long
| |
| 20:50 | * bennabiy waves | |
| 20:51 | <vagrantc> alkisg: would be fine by me.
| |
| 20:52 | alkisg: i've long wondered what if any of those are relevent or even harmful anymore
