There are a lot of others i saw in the last months:
Most times someone would try to blame the craphics-driver (and this may in some cases have been true). But it happens to all sort of graphics-cards
I think it’s not the graphics driver itself, it’s the power saving issue. Why ?
It comes in a variety of flavors:
- A brief blackout of the monitor
- A longer blackout (until the mouse moves)
- A separation of mouse and keyboard
- A real logout (with losing the session)
- It happens on random times (sometimes in a few seconds again, sometimes not in a day)
- It is not related to any single program that is in use
- It is not related to memory usage
- It is not related to on-time
- …
There is one program that I know of that does these tasks on a regular basis:
Energy saving !
An error in energy-savings could easily show the following behavior:
- let the screen go black (screensaver)
- disconnect the monitor (to let the monitor go to energy saving)
- disconnect mouse and keyboard from the session (to prevent changing anything while in sleep mode)
- end the session and logout
- ( it could even start to shutdown)
I have all Energy-saving disabled. So how can i go on ?
What program could try to act in behalf of energy saving ?
