Solved Maximum resolution not displayed; KVM issue?

el_gato · Dec 20, 2015

I am using a 27" QNIX QX2710 connected to an IOGEAR GCS982U 2-port Dual-DVI KVM. My Windows system has no problem displaying the native 2560x1440 resolution, but when I switch to my new FreeBSD installation, xrandr output only displays the following:

Code:

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 800 x 600, current 1600 x 1200, maximum 1600 x 1200
default connected 1600x1200+0+0 0mm x 0mm
  1600x1200  61.00*
  1280x1024  61.00
  1280x800  0.00
  1024x768  61.00
  800x600  61.00

I am able to successfully launch X and i3. Here is my xorg.conf:

Code:

EndSection

I thought it might be a video driver issue at first, and I'm using an old NVidia 8800GT so I installed nvidia-driver-340-340.93 and nvidia-xconfig, but when I use Nvidia instead of vesa and restart X I just get a default color pattern on the monitor from the KVM, but I think that is a separate issue; the vesa driver should be able to support 2560x1440, right? Any assistance would be greatly appreciated.

EDIT: Forgot to add the output of pciconf -vl:

Code:

vgapci0@pci0:1:0:0:   class=0x030000 card=0x11701462 chip=0x061110de rev=0xa2 hdr=0x00

  device  = 'G92 [GeForce 8800 GT]'
  class  = display
  subclass  = VGA

Not necessarily. It supports whatever VESA resolution your GPU's vendor decided to support.

Using NVIDIA's driver is the best way forward here. Do you see any error messages in /var/log/Xorg.0.log when using it?

There is an error for no valid modes which is why I tried manually adding the "2560x1440" mode to my xorg.conf, but that did not seem to help.

Those lines do not look good. Can you try adding

Code:

Option "IgnoreEDIDChecksum" "DFP-0"

to the Device section in your xorg.conf?

But please be careful. According to http://http.download.nvidia.com/XFr...README/xconfigoptions.html#IgnoreEDIDChecksum this might be dangerous.

That's done it! It looks great, and I don't see any weirdness in the display. Here is the Xorg.1.log output after adding this option:

Is there anything in particular I should monitor or check after ignoring this checksum? Thank you again for your help.

Glad that worked.

I'm not aware of anything. I believe you'll be fine if it works with your display.

Solved Maximum resolution not displayed; KVM issue?
