hardware information screen on clients boot is blocked

Asked by Eric Trezel

Hi,

I'm setting up an ltsp-cluster server and I've got a problem with hardware-info screen, that appears just before ldm.
The mouse doesn't work properly on it :
- No visible cursor
- No click

When I move the mouse, I manage to put the 'invisible cursor' on the 'OK' button and it highlights (it seems like look for the light switch in a dark room), then if I click, nothing happens, I must press the 'Enter key' to go to ldm.

I'd like either find the way to make the mouse work properly on that screen, or simply disable it, it is not usefull for me.

Thanks

Hi,

This message appear because the thin client mac address is in the root container of the control center.

If you create a container and move your thin client into it, you shouldn't see this windows again.

Ok, that's right.
But it has been hard to do this (not really intuitive, this interface), is there a doc somewhere about using ltsp-control-center ui ?

Thanks a lot

Hello,

The control center is being rewritten from scratch including this interface.
Preview of the new UI here :
https://ltsp-control01.stgraber.org/loadbalancer/overview
(drag & drop + ajax & co)

In the mean time, a good doc for this particular point is :

Ok, the movie is clear !

But : I go on thinking this screen at terminal's boot is not a good thing :
I'll have to boot every terminal one time, and move them in a container before users can work on them (since mouse doesn't work with this screen). Terminals could be registered in the control-center without that.
At least, administrators should have the capacity to disable this function.

It's not a criticism, just a feed back.
Thanks to you all (ltsp team and ltsp-cluster team) for your job !

Hi Eric, we applied some patches from ltsp-client-core_5.2.1 to get rid of this screen:.

1. Insert new option in ltsp postgres database :
{{{
insert into attributesdef (name,attributetype) values ('LDM_NO_CLUSTER_INFO', 1);
}}}

2. Add option in ltsp-cc web ui: `LDM_NO_CLUSTER_INFO`

3. Patch chroot /opt/ltsp/i386/usr/share/ltsp/xinitrc.d/I00-cluster and rebuild the chroot image:
{{{
--- a/opt/ltsp/i386/usr/share/ltsp/xinitrc.d/I00-cluster

     fi

}}}

To complete action "1." from "Ronald van Engelen said on 2010-03-27"

# Start Postgres SQL shell
$ sudo su postgres
$ psql

# Add a new attribute:
insert into attributesdef (name,attributetype) values ('LDM_NO_CLUSTER_INFO', 1);

# Define the allowed values for the newly created attribute:
insert into attributesdefdict (attributesdef_id, value) values ((select currval('attributesdef_id_seq')), 'False');
insert into attributesdefdict (attributesdef_id, value) values ((select currval('attributesdef_id_seq')), 'True');

# Leave Postgres SQL shell:
\q
$ exit

Thanks for the clarification on step 1. Can someone provide some more details on step 3

Jeff, we just wrap the existing check (! boolean_is_true "$CLUSTER_CONFIGURED" && [ -n "$(which ltsp-cluster-info)" ]) in an extra check to see if our new config-parameter "$LDM_NO_CLUSTER_INFO" is set.

So, the original code:

 if ! boolean_is_true "$CLUSTER_CONFIGURED" && [ -n "$(which ltsp-cluster-info)" ]; then
   export HOME=/root/
   ltsp-cluster-info
 fi

becomes:

if ! boolean_is_true "$LDM_NO_CLUSTER_INFO" ; then
   if ! boolean_is_true "$CLUSTER_CONFIGURED" && [ -n "$(which ltsp-cluster-info)" ]; then
     export HOME=/root/
     ltsp-cluster-info
   fi
 fi

I hope this clarifies things.

Can you help with this problem?
