[Nouveau] [Bug 54512] New: xrandr does not detect screen
https://bugs.freedesktop.org/show_bug.cgi?id=54512
Bug #: 54512
Summary: xrandr does not detect screen
Classification: Unclassified
Product: xorg
Version: unspecified
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Driver/nouveau
AssignedTo: nouveau at lists.freedesktop.org

dmesg log
Hi
I'm having some issue with my GeForce GT 540M card.
The problem is that xrandr doesn't detect my screen when I connect it with
HDMI:
HDMI1 disconnected (normal left inverted right x axis y axis)
But if I manually configure the HDMI device in xorg.conf, I can get video
output on my screen. So that part seems to be working correctly.
But as xrandr doesn't detect my screen, i'm unable to configure
dualscreen
correctly.
Attached you can find my dmesg log with drm.debug=0x4.
The last line is when I pulled out the HDMI cable.
I tested the current Ubuntu Quantal kernel, but also the daily kernel, and both
have the issue.
I hope somebody can take a look and fix the issue!
Thanks for all the work on nouveau :)

You're using an Optimus laptop, and the Intel GPU (which is the one X is using) is NOT wired up the the HDMI connector. The boot logo on your screen *is* nouveau's doing, and show's nouveau's (mostly, see below) done its job correctly. If possible in you BIOS setup, you can select "Discrete Graphics" mode and your NVIDIA GPU will become the primary adaptor and X should JustWork with the HDMI display. But, a great deal of manufacturers don't allow this mode, so it may not be available. Your last resort until X is able to handle Optimus properly (coming up in the next X server release), is to create an xorg.conf specifying two X screens, one on the intel (to drive the laptop panel) and another on nouveau (to handle your external outputs).> > Also notice something strange in the xrandr output: > HDMI2 disconnected (normal left inverted right x axis y axis) > > It now says HDMI2 somehowThis will highly depend on the ordering of which the Intel and Nouveau drivers load and create the connector objects. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

This is probably a bug in nouveau I'd say, but it deserves a new report.
I'm closing this bug due to it not actually being a bug :)
