I just installed installed 12.10, and suspend is not working. Here are more details:

  • When I select suspend from the power menu, the screen goes black (with the monitor still running), but the computer is still running. Num Lock works, but Caps Lock doesn't work [*]. The computer never enters suspend mode, but I can't get the monitor to respond either. The only way I can get out of this situation is to shut down the machine by holding the power button.
  • When I forcefully reboot it, I get the message "Ubuntu 12.10 has encountered an internal error". Apparently something is wrong with apportcheckresume.
  • I googled a bit and found this launchpad bug report. I installed the amd64 kernel from here; on this new kernel suspend works. But there are no drivers, so it's not a solution.

So, the question is:

  1. How do I fix suspend on the current kernel (3.5.0-17-generic); OR
  2. How do I install drivers on the mainline kernel?

A solution to either will solve the problem.

[*] How to debug suspend? seem to suggest this is a kernel hang?

    I have something similar. Suspend won't work if I press my power button, then click on the suspend button. But it will suspend by closing the lid, or clicking suspend from the dropdown from the top bar. Is weird. – davewasthere Oct 20 '12 at 23:04
  • I posted the same question here. There is more discussion, if anyone is interested. – Kevin Oct 21 '12 at 17:49
  • It seems like a bug and hence off-topic for the site. – Anwar Oct 25 '12 at 08:19
