            Bug ID: 296857
          Severity: normal
           Version: unspecified
          Priority: NOR
          Assignee: unassigned-bugs at kde.org
           Summary: [SuSe12.1] A momently corruption/flickering will
                    happen when the user startx with kde in dual-head mode
    Classification: Unclassified
                OS: Linux
          Reporter: xu.marico at gmail.com
          Hardware: Other
            Status: UNCONFIRMED
         Component: dualhead
           Product: kde

Environment :
OS:Suse12.1

Steps to reproduce:
1.Try to configure xorg.conf or use CCC to set the system as dual-head mode
2. restartx
3. you will see a momently corruption/flickering in the duration of startx

Tests and Workaround:
1. if we change the defaultdisplay as :0.0 in the script startx, the issue will
not happen 
2.we just start "xinit" firstly , and then export DISPLAY=:0.0 ,and startkde,
the issue will not happen. But if we don't export the DISPLAY, and startkde,
the issue will happen

It seems that the env DISPLAY will make KDE do different behavior , and
KCM_INIT will not run in the dual-head with the original env DISPLAY=:0 (if we
try to set it to :0.0, KCM_init will works well )
