** Description changed:
Hi
I tried the Ubuntu 12.04-beta2 LiveCD and decided to click on install
and after reboot I have only a black screen (Monitor shows: No Signal)
but the system is up as I can ssh into the box and reboot/shutdown it
remote. I have tried even a daily build but the same result no working
monitor setup
CD image used: http://cdimages.ubuntu.com/daily-live/current/precise-
desktop-amd64.iso
Monitor is a 24" with 2 HDMI Ports
connected to a Video Card with NVidia 9600 chip (HDMI Port)
I have tried also "nomodeset" but this change nothing. After that I
tried openSUSE 12.1 and it works with it's standard driver "nouveau" so
it seems an Ubuntu problem as Windows 7 works too with windows drivers
- (NVidia get not used on this box).
