10de:0dd8 [HP Workstation Z820, Z420, Z220]: System cannot use display port through Nvidia card.

[Jeff Marcom]

Problem:

System does not respond via kernel event when a display is connected via display port on nvidia card. No video/signal is issued to secondary display. No udevadm events are triggered when display port is connected.

No secondary display is shown in gnome-control-center displays.

Tested with latest kernel 3.5 rc7, and bug still exists.

[Jeff Marcom (jeffmarcom)]

This also affects the z420 workstation with nvidia card.

[penalvch (penalvch)]

Jeff Marcom, thank you for reporting this and helping make Ubuntu better. Did the display port work in a prior version of Ubuntu?

[Brendan Donegan (brendan-donegan)]

@Christopher - we haven't tested this system before. @Jeff can you try testing this with Oneiric?

[Jeff Marcom (jeffmarcom)]

This actually now looks like an nvidia driver issue. I installed oneiric, and plugged in a secondary monitor to the display port. I was amazed that it was actually working successfully. I then installed the proprietary nvidia graphics driver through jockey, rebooted and tried again. The secondary display was no longer working. I need to verify this to be the case with precise, as I ran through my whole test pool with the nvidia driver enabled because of an issue with suspend.

[Jeff Marcom (jeffmarcom)]

Bug is actually produced when using the nvidia-current package.

[Brendan Donegan (brendan-donegan)]

@Jeff - So it's the case here that if nvidia-current is used then the display port doesn't work, and if nouveau is used then the suspend won't resume from suspend?

[Flames_in_Paradise (ellisistfroh-deactivatedaccount)]

The new current-nvidia driver 304.43 is on it's way into the Precise, finally.

 see bug1037483

hopefuly this will resolve any issues like this one.

That version is no more supported; please open a new bug report if the actual archive found version also has the same issue.
