I have a strange one. I am using a Dell U2410 monitor. It just so happens that I have the same monitor described at http://elinux.org/Beagleboard:BeagleBoneBlack_HDMI
I loaded the image https://rcn-ee.net/deb/microsd/wheezy/bbxm-debian-7.4-2014-03-27-2gb.img.xz on my BBB When the HDMI output of the BBB is connected to the HDMI input on the monitor all goes well until the X desktop is started. As soon as X is started the monitor goes into power-save mode. Press cntl-alt F1 to get to a non-gui login and the display turns on. Switch back to F7 and the monitor goes into power-save. If I use a HDMI to DVI adapter and use the DVI input on the U2410, the X desktop display is OK. I can even use xrandr to change resolution to 1280x1024 (dvi input) which works fine. I have deduced that when the BBB gets the EDID info from the monitor, it changes to a mode that the Dell U2410 does not like but only with the X desktop. Anyone have any ideas? I am hesitant to blame the LXDE X server for this but anything is possible. . -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
