Re: DisplayPort Powersave Help
I am seeing the same thing with a machine using the DisplayPort to DVI adapter driving 2 Dell 21 inch LCD displays. When the screensaver puts the monitors to sleep, there are intermittent problems with the monitors waking up. At first, we had 1 monitor connected via the DVI port and 1 monitor connected via an HP DisplayPort to DVI adapter. User reported that it was always the monitor connected via the DisplayPort to DVI adapter. Then connected both monitors using a DisplayPort to DVI adapter, and can (intermittently) recreate the problems on both monitors using the any of the following xset commands...
xset dpms force off
xset dpms force standby
xset dpms force suspend
Environment is RHEL 5.3 64-bit, Nvidia driver 185.18.14
