Thank you! Try that.

Tested it again - is reproducable! And is seems that it does some deep things to system, because, even after a warm-reboot, there are some stange things, like Wordpad, MorphED, etc. loads textfiles correct (name shown in windowborder), but no text is invisible (or there is none)! After a cold-reboot everything works normal.
Think, this could be a issue of new Radeon-Driver.........

Will check that out to Peg2, Efika, Mini and PB, whether thy do the same.....

Workaround by setting monitor-blank-time to zero works, of course!

Quote:

You can set blanker delay to 3660 minutes or so, which of course only works if your system is not a 24/7 turned on device. Just make sure you edit both delay values for blanker and monitor blanking.

Ah, zero works, too. Makes sense.

Tested now on PB-G4 and EFIKA (Radeon9200S): Works as it should!
Sure that Peg and Mini will also do (test it later) - seems really a G5 or Radeon 9600 issue.....
I'll open a ticket to MOS-team!

Does it happen for both output ports ? It might be some specific issue with multi output support unrelated to the fact that you use two output ports at once or not.

Tested it now (I use only one monitor): You're right - changed to port near PCI-Slot and it works!!
