Hi, I upgraded from 10.10 to 11.04 a couple of days ago, and after grub it goes straight to black screen. I am running a Aspire5736Z,Intel Pentium T4500, Intel GMA 4500M card x64 bit machine. Had no problems with Ubuntu 10.10, worked perfectly. I notice quite a few other people have similar problems, but no resolution yet. Has anybody been able to ete this fixed?
