Intel graphics machines G45 and HD Graphics "has no monitor section"

[davshao]

For two separate machines with Intel graphics, one G45 and the other HD Graphics, using latest 3.7-DEVELOPMENT and after building dports from scratch locally post February 4, 2014, the monitor does not appear to be detected. From the resulting /var/log/Xorg.0.log:

Three days ago the driver for the latest-3.7 was changed to 2.21.15 Prior to that it was 2.21.9. If you are referencing 4 February, you might be not be using the latest. It might be worth updating dports and checking again.

sorry, here's a history link: http://gitweb.dragonflybsd.org/dports.git/history/HEAD:/x11-drivers/xf86-video-intel/Makefile

This is not a dports issue but most likely a shortcoming our drm/i915 kernel driver. For some reason, Xorg is unable to detect/set a default mode on the output the screen is plugged in. Running xrandr manually is a possible workaround.

Example for a 1280x1024 monitor: xrandr --screen 1 --output HDMI1 --mode 1280x1024

I was able to successfully start xfce4 on both machines using the xrandr suggestion.

I put in my .xinitrc file

xrandr --screen 0 --output HDMI1 --mode 1920x1080 &

for the Intel HD Graphics machine connected via HDMI -> DVI converter to a Samsung monitor and

xrandr --output LVDS1 --mode 1366x768 &

for the laptop.

This upstream bug report is mostly about the same issue: https://bugs.freedesktop.org/show_bug.cgi?id=66494

[ftigeot]

Adding Option "ReprobeOutputs" "true" in the Device section of xorg.conf as suggested in commit 1445a62da8a08acd8a732176d085fd098f68cec3 of xf86-video-intel confirmed as a correct workaround for this issue.

we are currently between runs on muscles so I'll try to regenerate this port specifically soon.

[jrmarino]

okay, I think this closes the issue. 0b8ec5adfdff07f8066ac6e8c7344f36832191a5
