Hi Joe, Sounds like buffer overflow in Linux video driver? Maybe video driver card related. Suggest trying another box. Or changing to a lower tech video driver card to see if things change.
I normally leave a much older version of Linrad running pretty much continuously on an old Pentium 100 on 40meters. No problems. Just works. Also, most modern kernels read the type of CRT from a serial prom inside the monitor. So the monitor type is sensed by Linux and can also change things in Linux (like the video driver software that is selected, the parameters uesd, etc.). warm regards, john, ni1b On Wed, 10 Jan 2007, Joe Taylor wrote: > I have some time to kill this evening, and I find myself wondering > whether anyone else on this list has experienced anything like the > following problem. > > When I put a Linrad system into regular use back in October, I noticed > that if I left Linrad running continuously, it always happened that > within a day or two I would come into the shack and find that the > monitor had "lost sync", or some such fault.
