Video Modes running Ubuntu 12.10 server in Parallels & screen blanking issue

Had some trouble in changing the terminal resolution even after installing the Parallels Tools, while the tools install allowed me to see my shared folders it didn't offer any way of changing the (tiny) 800*600 default screen...sooooo:

First determine the resolution you wish to have the console run at. Most cards support the standard VESA resolutions and their associated mode numbers. Pick the resolution you want and remember it's mode number. I wanted 1024x768x16 so my mode number is 791.

Type sudo su at the terminal prompt and enter your password. This leaves you with a root capable shell. 

Edit /etc/default/grub with:

nano /etc/default/grub

Find the line with GRUB_CMDLINE_LINUX_DEFAULT and add vga=xxx where xxx is the mode number. It should look something like:

GRUB_CMDLINE_LINUX_DEFAUT="quiet vga=791"

Save the changes and exit the editor

Update grub with the new settings. The settings will not take affect with out this.

update-grub

Restart your machine with the reboot command if you are still elevated or su reboot 

*****I choose 794 personally (1,280*1,024, 16bit) but goto Vesa Modes and fill your boots :-)

Is your screen blanking out after about 5-10 mins and hiding all those nice tmux screens!!!??

Edit /etc/default/grub with:

nano /etc/default/grub

Find the line with GRUB_CMDLINE_LINUX_DEFAULT and add consoleblank=0. It should look something like:

GRUB_CMDLINE_LINUX_DEFAUT="quiet consoleblank=0 vga=791"

then run "update-grub" & reboot....no more blank screen (epic win!) :-)
