I'm having quite an annoying problem. Just this morning I installed Ubuntu (alongside windows) and I immediately noticed that my cursor is flickering. I searched through askubuntu.com and I found that I needed to either disable the "Unknown display" (Not appearing in my case) or one of the two I currently have. The problem is that I need both of my displays. So, is there anything else I can do to fix this? Thank you in advance
At the blinking cursor, just hit ALT + CTRL + F1, and lo and behold, you will get a login prompt. From there you will be able to build a working xorg and get xbmc up and running.
Try holding down the shift key while booting the machine. Keep holding it down until you get the
Grub menu - hopefully. You'll want to edit the first entry. The next to last line usually, that starts with
linux /boot/vmlinuz-blah blah blah, and probably ends with quiet splash. what ever the line ends with, insert a space followed by
then boot the machine, read instructions at bottom of that page.
Good Luck, hopefully holding down shift key will get you into the grub menu.
nomodeset option is used for Nvidia graphics, other graphics need variations on the nomodeset switch. Look at the thread above if necessary.
