--- Comment #39 from Geoff N <[EMAIL PROTECTED]> 2008-09-18 03:29:55 PST --- And down the rabbit hole we go. The TVDACLoadDetect option appeared to work perfectly. I have been using a KVM for my tests. When I restart X, the trick that rendered the screen blank previously was to switch to another monitor. The EDID/I2C would fail and the VGA-0 screen would be disconnected. After adding the option for TVDACLoadDetect to xorg.conf, switching back to the screen after X had restarted showed a working screen. Xorg.0.log informed that the monitor was detected as a Colour CRT and it looked like I had a solution. However, restarting X without anything connected to VGA-0 didn't detect a default Colour CRT like the primary DAC. The screen was blank again and VGA-0 disconnected in the log. Seems like the KVM was providing some signalling that the Driver was picking up even when it wasn't the monitor in focus. After a bit of hunting around, it appears the KVM connects pins 4 and 11 to ground when the focus is off that monitor, so that graphics drivers are fooled into thinking a Colour CRT @ 1024 x 768 is connected. Turns out our customer may be using a KVM style connection for our blades, so the problem may well be moot. Would be nice though to force the same behaviour as the primary DAC in the absence of a connected monitor via this xorg.conf Device Option. Thanks again for your help. I might need that patch still (unless you know of another Device parameter) if the customer's KVM doesn't offer the signalling mentioned above. Query - when would you expect the git repo changes you made to xorg-x11-drv-ati to make their way into the Fedora community updates? -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
