Flashing Dell FP monitor
Debian testing - Using a new Dell FP monitor, I have the following problem -
Using the KDE desktop, it is fine for an hour or so. Then the display will
blank whenever the screen updates with a new window etc. Then after another
hour or so, the whole screen will start flashing every few seconds even if
left unattended. If I shut off the monitor, it will start the cycle again
the following day when turned on - OK for awhile, then flash with window
changes, then flashing regularly even if unattended - unusable at this
If I use the monitor with a Windows computer, it doesn't do this. If I plug
a CRT into the Linux box, it is also well-behaved. It's the flat panel with
the Linux box combination that's problematic.
Any ideas about this? It seems very strange to me that it takes awhile
before it acts up.
Thanks - John
