Minlogon Problems

[Guest]

Hello,
I have a custom shell, written in VC++ .NET (Native only, no .NET
framework). We have boot time constraints, and so I changed my shell from
Winlogon to Minlogon.

Everything seems to be ok, and then exactly 20 minutes after I boot up, my
video dies. My application keeps going just fine, just the video is gone.
When I use Winlogon, everything seems to be ok, but of course my boot time is
almost twice long.

Does anyone know why my video would crash after 20 minutes every time? If
not, does anyone know how to get Winlogon to boot as fast as Minlogon?

Thanks!
MJ

MJ,

15-20 minutes constant is related to video power management setting that turn off your monitor. Problem and solution are posted in
this NG many times before and you might use google to find them:

There are two types of solution:
1. To configure PM in registry so it does not turn off your monitor.
2. To use API function in your program you reset PM counters.

Look here:

Hello,


I have the same problem: With "minlogon", after 20 minutes the monitor goes
off.

My solution is:

I have set in STANDARD PC the power policy "Presentation"

I have added in TD the components "POWER CONFIGURATION TOOL" and "POWER
MANAGEMENT APPLICATION"

After this, the monitor never goes off.

You can verify this at the command line,writing the command:
POWERCFG /query
you can see if the setting monitor timeout ac is "never"

If not,with the command:
POWERCFG /CHANGE Presentation /monitor-timeout-ac 0
you can set the video goes off never...for ever
