<lionrouge_>
hi !
18:39
my ltsp clients screens turn black and never come back after screen locking. Debian 9 i386 server with XFCE
18:39
how can i fix it?
18:40
<alkisg>
lionrouge_: what is the client CPU? Intel skylake?
19:02adrianor1 is now known as adrianorg
19:14
<lionrouge_>
alkisg, much older :)
19:14
<alkisg>
lionrouge_: do you have epoptes installed, for easier troubleshooting?
19:14
<lionrouge_>
in server or client environment?
19:15
<alkisg>
epoptes in server, epoptes-client in client
19:15
<lionrouge_>
haven't heard about epoptes previously
19:15
<alkisg>
!epoptes
19:15
<ltsp`>
epoptes: Epoptes is a computer lab administration and monitoring tool. It works on Ubuntu and Debian based labs with LTSP or non-LTSP servers, thin and fat clients, standalone workstations, NX clients etc. More info: http://www.epoptes.org
19:15
<lionrouge_>
i will install it now
19:16
<alkisg>
For example, if your screen goes blank, it will allow you to access Xorg and query it with xset
19:16
OK
19:24
So when you install with epoptes, right click and open terminal, root, locally, and there run: xset q
19:25
Upload the result of `xset q` before and after the blanking...
19:31
<lionrouge_>
should i run it on server or client?
19:36Statler has left IRC (Statler!~Georg@p579FEB09.dip0.t-ipconnect.de, Remote host closed the connection)
19:39
<lionrouge_>
looks like i have no root in ltsp environment
19:39
need to fix it
19:41
<alkisg>
lionrouge_: see epoptes.org/installation for installation instructions
19:41
Then run the command via epoptes
19:54
<lionrouge_>
ok
20:01
i ran it under local user and there is no difference in xset q output
20:02
should i run it under root ?
20:05
<alkisg>
If you ran it via epoptes, then no, but xset q should tell you how it's blanked
20:05
screensaver or dpms
20:05
So if you didn't see anything, you did something wrong...
20:07
<lionrouge_>
both before and after screen lock i have: screen saver prefer blanking yes timeout:600 DPMS is enabled Monitor is on
20:07
and when i tried to unlock screen through epoptes it didn't work

re
20:32
<alkisg>
lionrouge: try screen broadcasting while it's locked
20:32
also try changing resolution with xrandr
20:39
*while it's blanked
20:39
Also mention the graphics driver used
20:39
And, if it happens with non-ltsp installations too
20:45
<lionrouge>
ok
20:51
screen broadcast while locked doesn't work - i see black screen too
20:52
it doesn't happen to non-ltsp installations though it's a different distro installed locally
20:52
video is Intel 82945G/GZ Integrated Graphics
20:53
the screen restores when i log off user with epoptes
20:55
i set up password for local root and can login to it either from ttys2 or from terminal in ltsp session
20:55
but epoptes still can't run local root terminal
20:56
so i run local user terminal with epoptes and then do su
20:56
xset q is the same as i mentioned before

<lionrouge>
alkisg, thank you for advices
22:21
i think i should better create a thin client server
22:21
looks like this issue doesn't happen with it
22:25
as i understand the issue is with authentication mechanisms that are needed to unlock screen
