Comment 63 for bug 28326

Here is a workaround that may work for some.

Since the problem is in the i810 driver, replacing that by another driver would avoid the problem. Some high end features of the hardware may not be available, but for general use, this works for me.

What you need to do is replace the i810 entry in the X.org configuration file with the vesa driver.

So, edit /etc/X11/xorg.conf and find the word i810. Replace that with vesa.

Before:

Driver "i810"

After:

Driver "vesa"

Reboot, and then you would be able to suspend/hibernate the computer.
