<alkisg>
Nah, LTSP isn't yet supported on dracut-based distributions like centos or fedora
08:39
<bcg>
I'll start my ltsp20+rhel8 work quite soon...
08:40
<alkisg>
Great :)
08:56* alkisg restarted his phd today after a few years of lag :D
09:31
<highvoltage>
congrats alkisg
09:32
<alkisg>
Ty!
09:32
<highvoltage>
I was considering starting studies again too but I need to put some further thought into it
09:33
<alkisg>
I actually started it back in 2008, but ...life happened
09:34
The good thing is that I was indirectly working on it anyway, all this time
09:36
<highvoltage>
ah good
09:37
life just doesn't want to stop happening at me so I just try to learn to roll with the punches

<elias_a>
Who is he? A side person of alkisg? :O
14:00
<mwalters>
a future alter ego, no doubt ;)

<elias_a>
Oh - soon to be dr... sorry and congratulations!

<mnevans>
I just wanted to thank Alkis for his help troubleshooting my reinstall of LTSP (19/20) in place of LTSP5. And apologize to everyone because the problems I was seeing were in failing to remember I have hardware that needs nonfree and contrib sources. Not an LTSP configuration problem at all.
14:38
<alkisg>
Hey mnevans; so all ok now? great!
15:29
<mnevans>
Once I had the relevant amd graphics code and microcode installed, reboot, I have graphics on the zotac/amd clients.
15:30
There's only one problem (of course...) Display comes up with an extended desktop, and opening settings to modify the display appropriately come up on the 'off screen' display.
15:31
So question is whether it is possible to set the display not to do this extended desktop by default, in perhaps ltsp.conf, ?
15:31
from a terminal window/modifying configuration, rather than through the gui/xcfe/lightdm display settings?
15:32
For instance is there and XRANDR mode setting to make in an INCLUDES=[crt_monitor] stanza for [clients]?
15:33
...is there an XRANDR...
15:34
The problem could be an unwanted horizontal reflection. I'm not sure, I can't see it...
15:34
going to look at man xrandr for ideas...
15:35
<alkisg>
mnevans: xrandr | nc termbin.com 9999
15:35
This tells us the problem
15:35
KERNEL_PARAMETERS=video=eDP-1:d
15:36
This in ltsp.conf, disables the phantom display
15:36
Where eDP-1 is the phantom output name
15:37
<mnevans>
termbin.com/u26x
15:38
problem is 1440x900+1440+0 (normal left inverted right x axis y axis)
15:39
<alkisg>
Which one is the phantom one, DisplayPort-0 or VGA-0?
15:40
Try xrandr --output VGA-0 --off
15:40
If this works, then VGA-0 is the phantom one
15:40
<mnevans>
so I put into ltsp.conf, KERNEL_PARAMETERS=video=0:d?
15:40
I'm not sure which one/ There's only one display output, and it is VGA connected to an HDMI adapter.
15:42
Sorry - wrong. It is Displayport --> VGA adapter that is real. HDMI has no connection.
15:45
Tried your suggestion - looks like VGA-0 is the active one. But the problem is that if I mouse across the left side of the display, the mouse
15:45
(the pointer) just vanishes into a display I can't see :)
15:58
<alkisg>
mnevans: reboot and try the other one
15:58
xrandr --output DisplayPort-0 --off
16:00
<mwalters>
mnevans: some microatx boards have an internal connector that shows up... sometimes they can be disabled in bios/cmos
16:01
I had several that would not disable the adapter no matter the bios settings... and had to go the ltsp.conf route... but it was was easier to do it via the bios when it worked
16:14
<mnevans>
mwalters - thanks - I will look. This is a bit like whack a mole :) I have two monitor sizes I am testing.
16:15
OK - I think I fixed this. The solution seems to have been, once the nonfree and contrib software updates were there,
16:16
to (wait for it...) just let X and ltsp.conf do its thing automagically. The login screen still comes up with a ghost extra display, but once logged in, it disappears.
16:17
In other words: in /etc/ltsp.conf, I commented out the [crt_monitor] settings I had tried to use to fix things earlier. Now to see if the behavior is good for an unsuspecting user...
16:20
Again - thanks everyone for your patience as I am figuring out LTSP setup again. This is all much easier in v20 than it was in v5 up through Debian/Stretch.
16:20
I am sure it has been a lot of work, so again: Thanks.
16:23
Is there any way I can contribute something useful to the effort?
16:23
(besides going away...:) )
16:26
<alkisg>
mnevans: you're welcome
16:26
Documentation and funding, probably; but no worries, have fun with it
17:56
<mnevans>
Would be happy to try to contribute documentation if useful. Is it possible to contribute some $? If so - please point me in the right direction?

And documentation goes there, in case you find something appropriate that's missing

<elias_a>
alkisg: What are writing your dissertation about?
19:17
<alkisg>
elias_a: in the long distant past, I've written an IDE and interpreter for an educational programming language, it's mostly about that
19:24
<elias_a>
alkisg: Oh - wonderful! Just get it done! :)
