Hi, I noticed that one machine here gives only the blank output with 3.4-rc's. The bisection lead me to affecting commit: commit e00e8b5e760cbbe9067daeae5454d67c44c8d035 Author: Alex Deucher <alexander.deucher@xxxxxxx> Date: Fri Mar 16 12:22:09 2012 -0400 drm/radeon/kms: fix analog load detection on DVI-I connectors Reverting this commit helped, it goes back to normal. On this system, the VGA monitor is connected to DVI over a VGA-DVI connector (and even VGA-switcher). So, yeah, it's a strange setup. But a regression is a regression. I'm willing to test any patch. thanks, Takashi _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
