-====== Boot - Boots to a black screen ======
-Blank or black screens generally indicate a failure feeding data to the Graphics Processing Unit (GPU) in your video card.  This can happen for a bunch of different reasons as different processes run as your system boots up.  You may notice flickers during boot - these are indications that different processes are starting up and interacting with the GPU.
-===== The nomodeset parameter =====
-When the grub boot menu comes up, press **e** to edit the correct boot line.
-Change
-<code>
-GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
-</code>
-to
-<code>
-GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
-</code>
-If this works, then you can [[http://askubuntu.com/questions/47506/how-do-i-install-extra-drivers|install proprietary graphics drivers]] which should get you going again.
-If you have trouble with the above, you can change the above line permanently in the grub configuration file.
-Boot into recovery mode (selection from the grub boot loader) and edit the file /etc/default/grub as per the above instructions.
-You can edit this file by typing:
-<code bash>
-vi /etc/default/grub
-</code>
-You'll have to update the grub menu:
-<code bash>
-update-grub
-</code>
-then reboot by typing
-<code bash>
-reboot
-</code>
-<WRAP tip>
-You can also try acpi = off and nolapic if nomodset also shows up as a black screen.
-Replace quiet splash with no splash to get an idea of what step your system is failing at.
