Comment 6 for bug 467841

OK I'll also post my theory about this one.
First I obtained the xorg log by booting the kernel in recovery mode and resuming the normal boot process to get a normal text console. No failed to restore crtc has appeared, but the connectors have no mode is still there in dmesg.
Then I tried startx which gives me the log which basically says that VGA is not connected, which is false. I guess that the flickering in the normal boot is due to X trying to start but failing to find a mode because it thinks that the vga output is not connected.
Hope someone can make sense out of this...
