My system with the same problem has "CN700/P4M800 Pro/P4M800 CE/VN800 Graphics [S3 UniChrome Pro]" as the onboard display adaptor on an Asrock 775VM800 motherboard.
Worked fine in 12.04 but after upgrade to 12.10 I get a brief flash of the splash screen followed by no video and no keyboard. Remote login via ssh works OK. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-openchrome in Ubuntu. https://bugs.launchpad.net/bugs/1086035 Title: [VM800/P4M800Pro/VN800/CN700] X fails to start after upgrade Status in “xserver-xorg-video-openchrome” package in Ubuntu: Confirmed Bug description: After upgrade to Ubuntu 12.10 the X server failed to start which worked fine before.
