[Bug 20195] Re: Laptop doesn't resume after S3

[Daniel Silverstone]

Hi Antonio,

Could you please take a look in /etc/default/acpi-support

Is the POST_VIDEO=true line enabled? Also is the
SAVE_VIDEO_PCI_STATE=true enabled? Those two lines govern two of the
mechanisms we use to save and restore the display configuration. On some
laptops they can break resume. (For example on my Toshiba Portege A100 I
have to disable both of those in order to prevent the laptop from
hanging on resume)

Could you try different combinations of enabling and disabling those
lines to see if anything helps? To disable a line, insert a hash (#) at
the start, and to re-enable a line, remove any hashes at the start.
