<eu^static-108-34>
I have a very strange damn NVIDIA problem if someone could help please
12:44
<alkisg>
eu^static-108-34: what kind of problem?
12:44eu^gwmonkberryco has joined IRC (eu^gwmonkberryco!6c221082@gw.monkberry.com)
12:45
<eu^static-108-34>
I made the mistake of trying to inslall the nvidia driver and now even though I've removed every instance of the thing, anyone that boots off the LTSP server gets the nv-glx missing on display error when you run glxinfo on the client
12:46
<alkisg>
LTSP 20+, chrootless?
12:46
<eu^static-108-34>
yes
12:46
<alkisg>
Is there an /etc/X11/xorg.conf?
12:46
<eu^static-108-34>
no
12:46
<alkisg>
What's the output of: dpkg -l | grep nvidia
12:46
<eu^static-108-34>
on the client?
12:47
<alkisg>
If you did run `ltsp image /`, it should be the same...
12:47
So either client or server
12:47
<eu^static-108-34>
also, if I login to the server directly, the glx stuff is correct
12:47
yes I did that command with "ltsp initrd" after
12:47
<alkisg>
OK, so what's the output?
12:48
<eu^static-108-34>
doing it now, I need to be root on the client correct?
12:48
<alkisg>
No
12:48
As the user will do
12:48
<eu^static-108-34>
ok
12:48
<alkisg>
dpkg -l | grep nvidia | nc termbin.com 9999
12:48
This will also put it to pastebin... tell us the url
12:48
<eu^static-108-34>
nvidia-prime-applet is the only result
12:48
and I put that on in an effort to correct this
12:49
<alkisg>
Did you install an nvidia .deb or a .run file?
12:49
<eu^static-108-34>
I just ran your file
12:49
I believe it was a .run file
12:50
<alkisg>
My? I don't have any nvidia files
12:50
Do you mean the nvidia driver from their site?
12:50
<eu^static-108-34>
yes
12:50
<alkisg>
Run this on the client: software-properties-gtk
12:50
<eu^static-108-34>
I just send it and it returned https://termbin.com/gedv
12:50
<alkisg>
I moved on to another question now
12:50
I'm asking how you installed the nvidia drivers on the server
12:51
Did you use a .deb installer, or a .run installer for nvidia?
12:51
<eu^static-108-34>
I replied I believe it was a .run file
12:51
<alkisg>
OK, I replied, Run this on the client: software-properties-gtk
12:52
Did you use that dialog to install the drivers? Or did you use a browser and went to nvidia.com and downloaded stuff?
12:52
<eu^static-108-34>
I went and downloaded the .run file
12:52
<alkisg>
OK, then just google on "how to fully install nvidia", I don't have any clues about it, I've never used that one
12:53
It works on the server because the server has nvidia
12:53
<eu^static-108-34>
I ran the software-properties-gtk command, what are we looking for in that result?
12:53
<alkisg>
software-properties-gtk is the proper method to install nvidia.deb
12:53
But you already said you didn't do that, so ok, close it again
12:53
<eu^static-108-34>
no the server does not have nvidia, just that the glx stuff works on the server
12:53
<alkisg>
The clients have nvidia?
12:53
<eu^static-108-34>
no
12:54
<alkisg>
...why did you install nvidia? :D
12:54
<eu^static-108-34>
there is an intel chipset but the client thinks it's nvidia
12:54
or so says glxinfo
12:54
<alkisg>
What's the output of `glxinfo | nc termbin.com 9999` ?
12:54
On the client, to see the problem
12:54
<eu^static-108-34>
I had another box on with a broken nvidia chip and was stupidly playing around with it
12:55
ok
12:55
sent
12:55
<alkisg>
URL?
12:55
<eu^static-108-34>
this time it did not return one
12:56
<alkisg>
!paste
12:56
<ltspbot>
paste: To avoid channel flooding, please upload text longer than 3 lines to http://paste.debian.net. Don't forget to paste the resulting URL here.
12:56
<alkisg>
OK, do this then ^
12:56
<eu^static-108-34>
sorry my bad
12:56
<alkisg>
Put the output of glxinfo there
12:56
<eu^static-108-34>
you should have it now
12:57
<alkisg>
I only have what you write here in IRC
12:57
<eu^static-108-34>
I just sent you an lspci from that box
12:58
<alkisg>
I'm not getting anything else from any other source
12:58
If you type a URL, I can go visit it
12:58
<eu^static-108-34>
https://termbin.com/uilb
12:58
<alkisg>
That's not glxinfo
12:58
I want to see the problem you're seeing
12:58
<eu^static-108-34>
i know here is that one
12:58
https://termbin.com/9w25
12:59
<alkisg>
name of display: :0
12:59
That's the problem?
12:59
<eu^static-108-34>
I'm not sure how to answer that, I'm logged into the box itself and running those commands
12:59
<alkisg>
"the nv-glx missing on display error when you run glxinfo on the client"
12:59
<eu^static-108-34>
I would imagine it to be display 0:
13:00
<alkisg>
You reported that problem
13:00
Can we see it in a pastebin?
13:00
<eu^static-108-34>
the glxinfo results?
13:00
<alkisg>
Yes
13:00
<eu^static-108-34>
ok

<Peter>
This is me now alkisg
13:02
<alkisg>
ok
13:03
<Peter>
how would you like me to post the results?
13:03
<alkisg>
However you like, we just want to see them in some url, be it text or image
13:03
You can't paste more than 2-3 lines here as irc will kick you
13:04
<Peter>
harlene@ltsp144:~/Desktop$ glxinfo
13:04
name of display: :0
13:04
Xlib: extension "NV-GLX" missing on display ":0".
13:04
<alkisg>
That's all the output?
13:04
<Peter>
no, I didn't want to post too much
13:04
<alkisg>
!paste
13:04
<ltspbot>
paste: To avoid channel flooding, please upload text longer than 3 lines to http://paste.debian.net. Don't forget to paste the resulting URL here.
13:05
<alkisg>
Put it there ^
13:05
<Peter>
ok
13:06
http://paste.debian.net/1184534
13:08
<alkisg>
Did you run something like this, on the server? sudo ./NVIDIA-Linux-x86-310.19.run --uninstall
13:08
<Peter>
no, not sure where that file is but I can try and locate it, if it's still there
13:09
<alkisg>
Peter: ok, I think you just didn't uninstall the driver. Google it, for example: https://askubuntu.com/questions/219942/how-to-uninstall-manually-installed-nvidia-drivers
13:09
After you uninstall it, run `ltsp image /` once more
13:10
<Peter>
I can try that, thank you. I have literally tried pulling out that thing all over before though
13:10
I don't have that particular .run file anymore
13:10
<alkisg>
Peter: then you'd need to re-download it, reinstall it, then uninstall it etc etc
13:10
Or you could just reinstall your ltsp server
13:10
In any case, it's really not ltsp specific, you can also ask in #ubuntu about it
13:11
<Peter>
I would just redo the server but there is so much work on this already, user accounts, etc
13:11
<alkisg>
Also read a newer guide: https://computingforgeeks.com/how-to-uninstall-manually-installed-nvidia-drivers-in-linux/
13:11
But you'll need to re-download the installer.
13:11
nap time, /me waves for now...
13:11
<Peter>
I will keep trying. Thank you for the fast responses, I was/am at my wits end and was hoping you'd have some magic
13:12
Thanks again!
13:12
<alkisg>
It's not related to ltsp, so...
13:12
I never even ran that nvidia-installer.run file :)
13:12
<Peter>
again, the problem only shows on clients, not the server login itself
13:12
<alkisg>
That's why I'm suggesting #ubuntu, because they'll know about this as it's not ltsp related, not because I don't want to help
13:12
That doesn't matter
13:12
<Peter>
which led me to believe it must be in the client image itself
13:12
<alkisg>
It's just a side effect
13:12
Nah
13:13
<Peter>
ok
13:14
<vagrantc>
23
13:14
<Peter>
I will download the file again and try the uninstall method, thank you Alkisg!
13:17
I'll post my results here later after I yank this damn nvidia driver out

Alkisg, you still here?
13:38
That was the fix!
13:39
I found a copy of the .run file, ran the --uninstall on it and rebuilt the image, and voila! Now, she runs like a charm. Thank you very much!
