I think the "trident" driver was the one I was using. But, I may be mistaken. Just to clarify, I never did get DPMS to work on the I-Opener previously either. I was using the BIOS to send it to doze which would switch off the backlight. When I upgraded the Xserver to 4.2.0, there appeared to be some sort of conflict between the BIOS blanking the screen and the Xserver even when DPMS was disabled in the XServer. Last night, I tried 3.3.6 again and it works as expected - the backlight turns off when it goes into doze from apm. When trying out the 4.2.0 server, I did have the Option "dpms" set in the monitor section. I verified this by running xdpyinfo and xset -q and I saw that DPMS was enabled and the extension was loaded. You probably know this better than me but it seems like there's some conflict between the BIOS apm and DPMS. I tried turning off apm both in the BIOS and in the kernel. DPMS does appear to blank the screen as expected but it doesn't turn off the backlight. I realize you (nor I) have the schematics for the I-Opener, but do you know how apm interacts with DPMS? Thanks for your help! -Bob
