I've been having problems getting a monitor to work in Xwindows on my new linux installation. Other monitors (NEC Viewsonic) work with XF86 on the machine. The monitor (V50) works on other (MS-Windows) machines. The monitor won't sync, gives up & blanks. Sometimes a picture flashes up briefly. It works OK in the linux text console, and also in basic VGA with win-3.1 I've selected and tweaked modelines to get scan rates & sync widths identical to those that work with the monitor when driven from other sources, and those given as "memory" settings in the monitor handbook. I've concluded that the card when driven from XF86 is producing composite-sync on h-sync which is causing the problem. As win-3.1 can produce proper syncs, it's not hardwired, it's the way XF86 has configured the card. This is not what I would expect as a default, is this a bug? Default modelines do not produce VESA VGA compliant output as a result, and some very common monitors won't sync. This is a serious bug. Is there a config option I can use to change this? Or is fixable by a patch? I'm still RTFM for composite syncs and not finding anything.
