I tried the "xset force" method and the monitor was stable in standby, suspend, and off. However, I can try setting the timeouts to avoid whichever stage is a problem in regular use. The monitor cycles normally on the same computer in Win98 through: 1) On 2) Blanked (still full power) 3) Standby or suspend (both use the same rapidly flashing LED) 4) Off (slowly flashing LED) In FreeBSD, the successful endpoint has been Standby or suspend. The difference is that standby has vertical sync and no horizontal sync, and suspend is the reverse. Both use similar power. Thanks again for your suggestions and help.

If your monitor actually manages to display a message, it's pretty safe to assume that whatever input it is getting that it does not like will not actually harm it and it is in fact safe to ignore it. >> The system is fine during full power mode and during the initial >> blanking of the screen which starts after 10 minutes of no activity. >> The warnings occur after the simple screen blanking and before the >> actual DPMS power down.

My guess is that either your monitor does not handle one of the three DPMS power states correctly or that there is a bug in the mach64 driver or perhaps there's even a hardware problem with the graphics adapter itself. Either way, you can probably work around it by skipping the respective power state. You can do this with the xset utility, if your window manager/desktop environment does not bring its own facility to control the DPMS timeouts. The usage is: xset dpms 'off' is the mode with the least power consumption, the unit of the timeout is minutes. Specifying 0 will disable the respective mode. You can test which mode triggers the warning on your monitor by testing each mode invidually at once: xset dpms force My personal guess is that it is 'standby' which your monitor does not like. -- ,_, | Michael Nottebrock | lofi@freebsd.org (/^ ^\) | FreeBSD - The Power to Serve | http://www.freebsd.org \u/ | K Desktop Environment on FreeBSD | http://freebsd.kde.org -- Rick Voland rpvoland@spamcop.net
