Comment 0 for bug 1514102

1. Original bug was where the graphics would normally work but every so often the screen would be corrupted with horizontal lines of junk.

After much research I found a primitive fix for that:-
* edit /etc/default/grub to add nomodeset to the GRUB_CMDLINE_LINUX
* sudo update-grub
* reboot

2. Now the system will only allow VGA 640x480 graphics

This is occurring on an Intel 829845G/GZ chipset
