HDMI and/or DisplayPort output #29

Closed xgonzalo closed 13 years ago

xgonzalo commented 13 years ago

Hi,

I'm using debian testing pinned to sid, after running the install.sh script and rebooting the machine, I get no extras outputs:

Screen 0: minimum 320 x 200, current 1152 x 864, maximum 8192 x 8192 LVDS1 connected 1152x864+0+0 (normal left inverted right x axis y axis) 310mm x 174mm 1600x900 60.0 + 40.0
1440x900 59.9
1360x768 59.8 60.0
1152x864 60.0* 1024x768 60.0
800x600 60.3 56.2
640x480 59.9
VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) DP1 disconnected (normal left inverted right x axis y axis)

Also, when I run optirun it starts another instance of X (:8) with low resolution on the DisplayPort monitor.

Notice that my machine is alienware m14x with sandybridge.

Erm, I need to clarify things. You have additional panel connected to DisplayPort, right? Does your main laptop screen work when external panel is connected? Could you install nvidia-xconfig and run nvidia-xconfig --query-gpu-info? Also provide me /var/log/Xorg.8.log.

Yes! The laptop screen works normally whith the displayport connected, actually the main X instance does not recognize the DP as connected at all. Instead, the DP show the output of geforce X server (:8)

nvidia-xconfig:

ggorosito@glaptop:~$ nvidia-xconfig --query-gpu-info Number of GPUs: 1

GPU #0: Name : GeForce GT 555M PCI BusID : PCI:1:0:0

Number of Display Devices: 0

In the list they said that no one is getting external display working, I'm getting it "working" but with poor resolution, how do I try to startkde there on debian?

Well, as I know HDMI and display ports are often connected directly to nVidia card, while main laptop screen connected to Intel card. I've never run across such configuration and wasn't able to test it. debumblebee in current state isn't solution now, as you have two separate video cards, and two displays. I don't know if it's possible to join them, as they require incompatible drivers and libs. I think it's possible to launch two separate X screens for serving stuff on each monitor, but you cannot run the same instance of any DE on two X screens simultaneously. Though it requires certain amount of manual work.

Here are some hints in your quest: xinerama and xdmx. Though I don't have any experience with them, google is your friend.
