This question already has an answer here:
I left my computer on overnight and when I came to it this morning it offered to update (I'm on Ubuntu 12.04). So I updated and restarted, now when I want to login, I get the message:
Could not update ICE authority file /home/user/.ICEauthority
I'm getting this on all accounts. I can't see a way to get into the terminal to sort this out, as various threads I've found suggest. If I use Ctrl+Alt+T nothing happens. If I use Ctrl+F1then just go to a black screen.
I tried using an old live CD (Ubuntu 8.04) but couldn't get to terminal via that either.
I made usb stick to boot 12.04 from but I have no option to boot from usb on the computer (it has USB sockets, but it's an old desktop).It's only got CdROM/HDD/Network boot as options.
I can't burn a boot CD of 12.04 because the file is too big.
Can someone suggest a way to get to the terminal so I can fix this?
