I have recently installed Ubuntu 13.10 64-bit.
It was, by default, using the Nouveau display driver, however, this caused suspend to fail. I installed a proprietary driver which resolved that issue but created an ugly low res boot screen.
How can I fix it?
This is the solution that worked for me. (for those who have this common issue)
Run in Terminal
sudo apt-get install v86d
gksu gedit /etc/default/grub
Replace Line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
New Line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset video=uvesafb:mode_option=1920x1080-24,mtrr=3,scroll=ywrap"
Replace Line:
#GRUB_GFXMODE=640x480
New Line:
#GRUB_GFXMODE=1920x1080
Save & Close
gksu gedit /etc/initramfs-tools/modules
Add Line:
uvesafb mode_option=1920x1080-24 mtrr=3 scroll=ywrap
Save & Close
sudo update-grub2
sudo update-initramfs -u
