[Acer Aspire V5-573G] suspend/resume failure

[bp0]

I'm running packages from ubuntu and xubuntu. When I resume from suspend, I have to type my login password twice (in two separate lock screens) to get back to my previous session. This time I accidentally alt-tabbed while on the second (new ubuntu) lock screen, and couldn't get the login text box back in focus, so I selected 'suspend' from the drop down box, but then couldn't find any way of waking my laptop back up.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.14 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Tried this kernel: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-trusty/ and suspend works fine. However, in case it's relevant, I use bbswitch and installing the 3.14 kernel threw an error relating to this - possibly because I don't have the source package installed?
