Sam- On my laptop, which is using ACPI (default with the newer distros/kernels), I see see the same message in my Xorg.0.log (WW) Open APM failed (/dev/apm_bios) (No such file or directory) However, I do see the following from DPMS (II) Loading extension DPMS (**) Option "dpms" (**) RADEON(0): DPMS enabled Do you have Option "dpms" in your monitor line of xorg.conf? Alternatively, if your computer has apm bios, you can add acpi=off to the kernel entry in /etc/grub.conf and reboot. Some server class hardware (machines with ServerWorks chipsets) don't have an apm bios. Also, Are you running the screensaver? If you are running Gnome, go to Preferences > Screensaver and in the Advanced tab, make sure that Power Management Enabled is selected. Hope this helps. -- Sean
