Hello, I have just recently done a fresh install of SuSE Professional 7.3. I had a running system that crashed hard (harddrive failure), and I had to replace it. With my old system, the screen would blank after a period of inactivity. The monitor would show a short error message "Invalid sync." and then shutdown into standby mode. This was ok, and I figure this is how it is supposed to work. With the new system, I get the same behavior as with the old, providing I haven't had any X sessions. If I have had an X session, the console blanks, and the monitor issues its "Invalid sync." message. Then it shows the message "Invalid scan freq." while showing wavy horizontal lines interspersed with an occasional wide greenish band going up the screen. The monitor does not go into standby mode. When I move the mouse (gpm is running) or type a character, the console returns to normal, and the monitor briefly displays the frequencies 38kHz/60kHz. Could this behavior have something to do with the "vga=" line in /etc/lilo.conf? The old system had "vga = normal". This freshly installed system has "vga = 788" in it, I assume by default. Could it have something to do with APIC? The entry for the default kernel, which I have been booted into when this happens, shows the line: 'append = "enableapic vga=0x0314 hdb=ide-scsi"'. The monitor is a 19" Cornerstone Color 45/101sf with horizontal scan rates from 31 to 101kHz and vertical scan rates from 50 to 160kHz. The sync on this monitor is Separate, H, V or composite H/v TTL level, or Sync on Green at 0.3 V p. (I am guessing this last explains the green bands.) Regards, Sean -- Theo.
