Black screen of death on Ubuntu boot
 
Hi, since a few days ago after selecting Linux from the grub menu (dual boot with Windows 7) it hangs on a BSOD (the one with the blinking underscore in the top left in 800x600 resolution). Also the timer has disappeared from the grub menu to auto-boot into Ubuntu.

When it hangs at the BSOD the HDD sounds like its loading but nothing happens. I *think* the cause might be the other day I updated my NVidia driver in 7, the PC shut off and when I restarted there was totally no display (I rolled back the drivers which fixed it). Since then it booted into Ubuntu sucessfully once but it's never done it since.

I've tried adding that i915.modeset=0 to the grub file but to no avail. There is absolutely no output. I've been using a LiveCD to access all my college work, et cetera, but it's not overly convinient as you can imagine. Windows is woking fine.

(I'd reinstall but I'm quite proud of my transmission ratio and don't want to lose that :P)

You've got to be joking. You would like to preserve your transmission ratio.

Back up your ~/.config/transmission.

Took me months to get it as high as it is. xD Thanks, I'll try and that and ·hopefully· it'll work (though I think it's a graphics card issue :P)

I've tried to reinstall using two different versions of Ubuntu and a Linux Mint DVD now but they all hang on loading screens or blank screens in the LiveCD. Any ideas? o.O It was probably time I made myself a new PC anyway but I can't work out why this has happened. Parsix Linux seems to be the only LiveCD that actually boots, and its quite old so I'm reluctant to install that. :/

You could try going to a terminal by using Ctrl+Alt+F1 then typing nvidia-xconfig to create yourself an xorg.conf.

I got the xorg.conf using the recovery console but there's no way to copy it to anything else to show you the output since no LiveCDs are booting now. I'll get back to you when I've resolved that. Another thing to note is that the system clock keeps setting the time to seemingly random hours but the minutes are correct? It could be a BIOS/CMOS fault, but all this only seems to have occured since I updated and rolled back the Windows NVidia drivers.

Replace the battery just to eliminate another potential source of problems.

I didn't have a spare CMOS battery, as a precaution I reset the BIOS settings and swapped the HDD cables around (just in case it wasn't booting because I'd set the wrong disk/partition options in grub). It then booted from a Linux Mint CD which I installed on the secondary HDD. I tried to boot into Linux Mint from the HDD after installing but it gave me a grub rescue console. I booted from the Ubuntu disk and it hung on the BSOD...before starting like normal. So it's fixed though I'm not quite sure how.
Thanks for everyone's help. :D
