[Ltsp-discuss] LDM freezes

[Lars Madsen]

I'm having some issues with LDM that simply freezes or the login box disappearing after the terminal have been sitting idle for a while (without anyone being logged in). This means that basically everytime someone wants to use the temrinal, they have to forcefully reboot it.

Any ideas?

Terminals: HP T5530
Terminal image: Ubuntu 12.04

At a glance, it sounds to me like a power management issue. If that is
the case and you have BIOS/UEFI-level power management defaults, you may
be able to disable something there as a workaround.

There does not seem to be much available under power management in the
bios. Mostly something about wake on lan.

I'm wondering if it is a power management setting in the image it self
such that it for some reason goes into power same mode. Same thing as
the LDM greeter going to a blank screen. It would seem that when
coming back from the black screen not everyting is working properly.

Anyone know how the blank screen on LDM idle can be avoided?

I'm currently considering writing some cron scripts such that say
every 10 min or so, if no-one is logged in, restart LDM. And if the
time is not within say {7am .. 6pm}, then powerdown the terminal.
