Upgraded 8.04 to 8.10 on an Acer Extensa 3100 laptop with 915/910-based graphics. After logging into KDE 4 I've got the same repeated flickering of the internal LCD display every ten seconds until I disabled KDE4's "detect RandR (monitor) changes". As described above, manually calling XRandR command line tools causes flickering while the driver tries to detect which displays are currently connected.
