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
12:12gbaman 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 :)

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)

20:39
<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?
20:46bennabiy_away is now known as bennabiy

<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
