My laptop is Asus N53S. I'm using Ubuntu 12.04 LTS. Installed bumblebee to use nvidia optimus (Nvidia Geforce GT540M) - animations, performance in games are excellent.
But sometimes when I'm working with some programs I'm getting distorted display. Please look at screenshots:
I have an UX32VD with Optimus - I have used the following kernel options, and have never seen corrupted images..
Run this command in a Terminal window (Ctrl+Alt+T):
gksudo gedit /etc/default/grub
That opens /etc/default/grub in a text editor. Add the following line to the file:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nmi_watchdog=0 apparmor=0 pcie_aspm=force drm.vblankoffdelay=1 i915.semaphores=1"
Save the file and quit the text editor.
Run this command to regenerate grub.cfg:
sudo update-grub
Reboot afterwards.
