View Full Version : [ubuntu] Live CD works but no display after install

October 11th, 2010, 03:51 AM
Hi guys,

I have this problem where the 10.10 LiveCD 64-bit works (as in I get full resolution display and no video issues at all). But after install, the OS boots successfully but there's no display. I know it's successful because I was able to login in the dark (sound works).

Here's what I have:
HP m9340f (NVIDIA GeForce 9500M GS with HDMI)
46" Sharp connected via HDMI
Windows 7, works fine.

Here's what I tried with no luck:
1. CTRL-ALT-F1 still doesn't show anything on screen, no terminal
2. Connected via VGA
3. Connected another 17" monitor via VGA, rebooted
4. Added vga=789 in grub before booting

The weird thing is that I had 10.04 before and it was working for a while then it suddenly stopped working. I figured I'd wait until 10.10 but I now have the same issue. I haven't tried 32-bit... I can give that a shot in a bit.

Any ideas?](*,)

Boot up using the livecd again and go to your home folder of the one that doesn't work and output the file ".xsession-errors". something in there may give us clues to what's going on.

Seems to be related to the nvidia driver. I think I remember an update to the driver when all this started on 10.04. I only tried 10.10 since which probably has the same update or newer. I don't know to change drivers though if I can't see anything...

I tried 32-bit and 64-bit.

What driver is the live cd using?

Same problem with Kubuntu.

Any ideas anyone? :(

Okay. Found this:

I've tried everything from that page and still no luck :( I've never had a successful boot since some kernel update on 10.04.
