If your monitor actually manages to display a message, it's pretty safe to= =20 assume that whatever input it is getting that it does not like will not=20 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= =20 power states correctly or that there is a bug in the mach64 driver or perha= ps=20 there's even a hardware problem with the graphics adapter itself. Either wa= y,=20 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=20 environment does not bring its own facility to control the DPMS timeouts. The usage is: xset dpms <timeout until standby> <timeout until suspend>=20 <timeout until off> 'off' is the mode with the least power consumption, the unit of the timeout= is=20 minutes. Specifying 0 will disable the respective mode. You can test which= =20 mode triggers the warning on your monitor by testing each mode invidually a= t=20 once: xset dpms force <standby|suspend|off> My personal guess is that it is 'standby' which your monitor does not like. =2D-=20 ,_, | Michael Nottebrock | lofi@freebsd.org (/^ ^\) | FreeBSD - The Power to Serve | http://www.freebsd.org \u/ | K Desktop Environment on FreeBSD | http://freebsd.kde.org --nextPart1464229.NQnKyPFCio Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (FreeBSD) iD8DBQBDXSWFXhc68WspdLARAhteAJ4nksK0CScIwqwj5F5VQiIRnVp3OQCfZmvT nsk7QKAnl7fWDwlafN/S6a4= =NWhF -----END PGP SIGNATURE----- --nextPart1464229.NQnKyPFCio--
