Description Nikola Pajkovsky 2011-07-28 12:34:50 UTC

Description of problem:
last update of xorg-x11-server-utils breaks xrandr. I have a laptop in docking station (T500) and other monitor (SyncMaster 2243bw). Monitor is connected to docking station by VGA cable.

$ xrandr -q

I was using this command for almost an year and it works as charm. Now when I trying to mirror only laptop display survive and SyncMaster has some random non-sense. 

$ xrandr --output LVDS1 --auto --output VGA1 --auto --same-as LVDS1

$ cat ~/.xinitrc 
#!/bin/bash

[ -f ~/.Xresources ] && xrdb -merge ~/.Xresources

#xrandr --output LVDS1 --auto --output VGA1 --auto --same-as LVDS1

Comment 2 Dave Airlie 2011-07-28 15:27:08 UTC

can you confirm downgrading this package helps as you may have picked up a new driver + server stack as well.

Comment 3 Nikola Pajkovsky 2011-07-29 09:37:49 UTC

ok, it's not a xrandr, but it's xorg-x11-drv-intel; thanks

Comment 5 Adam Jackson 2011-08-18 15:21:17 UTC

I'm unable to reproduce this on as equivalent of a setup as I have handy (Dell 2005FPW which is the same size as the Samsung, otherwise identical).

kernel-2.6.32-188.el6
xorg-x11-drv-intel-2.16.0-1.el6

Please reopen if this is still an issue for you with a current 6.2 image.

Comment 6 Nikola Pajkovsky 2011-08-18 15:59:50 UTC

intel-2.15-stable.patch patch fixes the issue...I forgot to close it :-/
