Can't always resume from Suspend

[deerpic]

For some reason, twice in the past week, I could not resume from Suspend. My computer , an ASUS laptop, had been going steadily for nearly 60 days without a reboot, only suspending when I wasn't using it. It had always come back fine until a few days ago. I'm using Mint 17 Cinnamon 64-bit, and my swap UUID is correct. Any ideas what would cause this out of the blue and only result in a failure to resume every once in a while?

david@Hoth ~ $ cat /etc/initramfs-tools/conf.d/resume

I'm a bit of a noob but when I had problems waking my computer under Mint (black screen) I was able to resolve them by replacing the nouveau graphics driver with NVIDIA's proprietary driver.

As drw said, I'd certainly install the non-free Nvidia driver. You might want to disable hibernation (suspend-to-disk) as well:

When I type

Code: Select all

 cat /etc/initramfs-tools/conf.d/resume

I get

Code: Select all

cat: /etc/initramfs-tools/conf.d/resume: No such file or directory

. Is there any good reason for this? I'm having the same problem you're having. When my laptop comes out of suspension, it halts at the login screen. Ctrl-Alt-Backspace does nothing, the only Magic Sysrq keys that do anything are Alt-SysRq-O and Alt-SysRq-B. My problem is consistent, never intermittent. Always have to restart my laptop to get out of suspension.
