Comment 13 for bug 777493

after thoroughly researching this for a couple of weeks, and trying every suggestion possible ::

- checking /var/log and updating /etc/default/grub
- using current ppa (binary and source)
- using older nvidia drivers
- removing all display related drivers
- downloading and installing from nvidia
- clean install then one strategy or another
- purge drivers and re-install one or another strategy

after entirely too much pushing and pulling -- the only way to cleanly boot into graphics mode is to use "vesa" driver in the xorg.conf (and uncomment 'vesafb' in /etc/modprobe.d/*.conf ) {good luck..}

also try adding "nvidia" to /etc/modules .. without the entry in /etc/modules, 'modprobe' shows it missing, even though it is in fact there, and dkms shows the module current, and there appear to be no errors in kern.log or dmesg - at various points X would complain that there was no /dev/fb0 or just that there was an I/O error {no telling what actually got this working somewhat}

any way to slice it, X will not load the driver..

it would be helpful if the installer could report on the device status or at least have an option to check all of the critical areas to see if things have loaded correctly and then produce a report showing all of the relevant details..

of course, downgrading/clean-installing to 10.04 did not work either - none of the graphics modes worked on this particular machine.. (a 64bit AMD with G92 / 9800GT )
