[BozemanLUG] ATI Card, Linux, & an Optiplex 960

[Warren Sanders]

By chance are you using a KVM? I discovered using those DP to DVI converters will not work with a DP KVM. It wants straight DP. It might work to HDMI but I'm not sure. 

Other than what Scott suggested, have you checked the monitor mode to be sure it's looking for digital signal and not strictly only looking at VGA? 

I recall some Dell PC's out of the box refused to show a display until you first used the VGA to change the BIOS to allow it to use the on-board despite it being set by default to auto detect.

Okay all, I have a mystery for you all to ponder. 

I am using an Dell Optiplex 960 and I installed a PCI ATI Radeon card that has two Display ports. Off of one of the display ports I ran a Display port to DVI connector and hooked my monitors DVI cable into the Display to DVI cable. 

I basically have no display to work with. Running Ubuntu Mate doesn't seem to give me anything to make work. If I boot it into Linux I have a ton of horizontal lines and distortion. I I boot into windows I will never see any image all. Monitor does not even detect a signal.
