On Release Candidate, launchpad bug #304871 is back in spades. Integrated Intel graphics i845 boots to black screen on CD Live and install on Ubuntu and Xubuntu.
I had to boot CD Live, edit command line, remove quiet splash, add single to get recovery mode. Then in root prompt nano /etc/X11/xorg.conf to add Option "NoAccel" just after "Configured Video Device".
Same thing on install.
Update Manager lists 49 updates already, NONE of them in xorg to fix this bug again.
Performance is sluggish on scroll etc to say the least.
What happened? It was fine on Beta?
