Ubuntu/ Xubuntu 12.04 Precise Desktop LiveCD/DVD Problem: No Video
Tried to run, in order
- Ubuntu 12.04 LiveDVD (64-bit Desktop): Burnt to DVD and booted from disk
- Ubuntu 12.04 LiveCD (64-bit Desktop): Written to USB stick via usb-creator and booted from USB
- Xubuntu 12.04 LiveCD (64-bit Desktop): Written to USB stick via usb-creator and booted from USB
In each case, got the same behaviour
- System would boot from the disk/ USB
- Would be presented with the splah/ progress screen (the one with the dots on plain background for Ubuntu and bouncing progress bar with background image for Xubuntu)
- After that screen would fill up with coloured noise, random black/ coloured pixels all over the screen
- Unable to do anything other than a hard reboot
This was with using an old NVidia GT 240 card (which works fine with Lucid 10.04.4 64-bit Desktop). Complete system specs in the signature...
Next I went into BIOS and forced it to use the onboard Intel graphics (Intel DG33FB board with Inteal GMA 3100 graphics) and Xubuntu booted up fine and got into the desktop with no problems. Launched a few apps and all seems fine.
Based on my advanced analytical skills (!) I conclude there is a problem with the graphics driver on the LiveCD/DVD in Ubuntu/Xubuntu.
I guess I could fix this by installing with the onboard Intel video and then upgrade to the latest NVidia drivers via the safe mode command line (have done this many times before) but I guess I'll just wait for 12.04.1 instead!
