I'm using gentoo with xorg 1.11, radeon 6.14.3. Try with xorg/radeon/mesa git and same results Other distro are affected. With live-cd ubuntu/fedora + gnome/kde/xfce + 32/64 bits same results. xset dpms force off/suspend/standy don't work. Instead of switching off, my screen become slowly white. vbetool switch off the screen but after awake they are have artefacts and the only solution is a reboot. I've notice that in the log of Xorg I don't have (II) RADEON(0): DPMS capabilities: StandBy Suspend Off

Can you attach a copy of your vbios? To get a copy of your vbios: (as root) (use lspci to get the bus id) cd /sys/bus/pci/devices/<pci bus id> echo 1 > rom cat rom > /tmp/vbios.rom echo 0 > rom

Thanks I have attached my vbios.
Try with and without kms, same results. I've notice that pm-suspend and pm-hibernate are affected. My screen turns off, but after 1 seconds he awake, I've a black screen with a prompt and he become white with luminosity at the maximum. The only solution is a hard-reboot. But hibernation is apparently functioning because when I restart I've my desktop directly.
Upgrading my bios solve the problem xset, suspend, works
