[ltp] T40 - Consensus on the blank screen coma (LCD sleep) issue?

[Hartwig, Thomas]

I'm not finaly sure, but as I mentioned in an earlier posting I think 
you should turn off CONFIG_APM_DISPLAY_BLANK in your kernel config.

Look at the thread "[ltp] T40: Suspend/Resume and Standby now 
working...", there you will find sample config files and dicussions 
about it.

Greetings
Thomas
