randr does not recognize HDMI

Postby linux_user_999 on Fri Jul 15, 2011 11:42 am

I am trying out LMDE and am having some trouble getting my HDMI output to work. I used to use xorg.conf and the nvidia proprietary drivers but that does not seem to work in LMDE. I am not sure how to go about configuring randr to find the HDMI. I'm still pretty new at Linux so details are good. The following is some output from my system:
$ xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192
DVI-I-1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 376mm x 301mm

I came across your question by accident, it is late reply and I'm just guessing, but:
Are you sure that your card has independent HDMI and DVI ports? Mine also has both connectors, but they are in fact just one port with two connectors wired to it (so the same video signal goes into DVI and HDMI simultaneously). If it is the case, you can configure the HDMI ouput using
Code: Select all
xrandr --output DVI-I-1 <options>

Mine is recognized as HDMI-1 by xrandr, though.

EDIT: Oh, I did not mentioned you have two graphic cards. If DVI and HDMI are on different cards, then of course are independent...
