I was experiencing the same flickering with my dual-monitor setup in KDE4. I disabled the TV and TMDS-1 output (I got the names from xrandr, which was showing them as additional outputs to LVDS and VGA), by changing my /etc/X11/xorg.conf file with the following options:

Section "Device"
        Identifier "Configured Video Device"
        Driver "intel"
        Option "monitor-TMDS-1" "dvi"
        Option "monitor-TV" "tv"
        Option "monitor-VGA" "vga"
        Option "monitor-LVDS" "lvds"
EndSection

Section "Monitor"
        Identifier "dvi"
        Option "Ignore" "true"
EndSection

Section "Monitor"
        Identifier "tv"
        Option "Ignore" "true"
EndSection
