Hi, * I leave a low voltage LED display plugged in to the card using the DisplayPort connection and that's permanently turned on. *I'm using Debian packaged fglrx version 12-6-2/8.98.2. * DPMS (thank you for that tip), KDE (4.8.4)'s power management and screen saver are turned off.
About 50% of the time the LED screen is still showing my desktop when I get up in the mornings or come home from work; the rest of the time it's blank. Sometimes you can turn your back on the screen for just a few minutes and its blank. Of those blank screens 20% of them don't recover; so far I'm on a winning streak betting with myself if the display is going to work. Similarly, if my house mate turns of the LED display then the Radeon HD 6950 goes in to deep sleep without recovering. I can connect through SSH with my Android phone or tablet and "sudo shutdown"; as sometimes a reboot isn't enough to bring the card out of sleep. It takes 2-5mins for the xorg process to finish, during that time the process hits 100% of single threaded CPU utilization. The .xsession- errors log file often has lots of DBus errors. Mostly I issue a "kill -9" just to speed the up the shutdown. Getting rid of the Debian package "firmware-linux-nonfree" which contains the BIOS blobs for these cards for the Radeon driver made a significant improvement from the almost always doesn't recover to now if the LED display is sleeping and I turn the projector (HDMI) on, more often than not both displays will work. There's nothing worse than a black screen of doom!
