When I open Ubuntu software center, once it fully loads, it immediately disappears. Not even in system manager anymore. I'm on a Acer TravelMate 260, 768MBram, 5400rpm 80GB HD, intel graphics. Rhythmbox doesn't even open, but that for another thread (unless someone has a fix for that too)
apt-get update/upgrade does not fix the problem. I've been doing that everday as new updates come in. I'm hoping the issue is fixed soon, but not sure as it seems the repos are ready to go to court.
