Re: D54250WYK, displayport 1.2 dual monitors and Ubuntu (trusty tahr)

Hello Sylvia,

 

Thanks for your reply, the new driver was released for trusty tahr and I tried installing that to no effect.  I have finally had an opportunity to try loading Windows 7 64-bit.  I just loaded it about 2 hours ago and many of the drivers were missing, so I downloaded the latest driver bundle (May 2014) and installed the graphics driver from that for my test.  It requested that I reboot, but now I after I reboot, I have no display output at all.  The oddest part is that I don't even get display output for the BIOS.

 

I disconnected from the displayport hub and tried the cable directly to a monitor (from the NUC).  I unplugged the power from the NUC so that I could be certain it was off.  I replaced the power and turned the NUC back on and I still have no output.  I tried another displayport cable and the other monitor both.  I went back to the hub with another cable and still no output at all.  This seems very odd to me that I suddenly have no video.  Please help!!  I do have the NUC audio connected and can hear the windows sounds (like it finished loading).

 

I strongly prefer not to use DVI/VGA or adapters for these, since this was part of the reason for my monitor and NUC purchase--to use the newer displayport/hdmi technology. Unfortunately the monitors do not support HDMI, so I am left with DisplayPort capability only.
