for the past 3 weeks I've been working on setting up an old hp pavillon a1540n with ubuntu server 14.04. Main problem is the hibernate/suspend process. I've done a lot of reading and made great progress thus far, but I feel I reached a point where Google isn't helping anymore.
Right now, pm-hibernate saves to disk correctly, computer stops making sounds, but the screen shows a blinking cursor. After that, no event can wake it up and I have to force shutdown by pressing and holding the power button. On restart however, it loads perfectly and resume where I left. This leaves me thinking that somehow no events can wake it up.
Here is a short list of any effective actions I've done that I can think of: -Removed graphics card and tv tuner card -Updated BIOS to 5.07 (no new option for power management though, but it helped) -Updated driver to nvidia 330 (latest recommended)
Doing basic pm-debugging (basic-pm-debugging.txt#178 on mjmwired dot net), using reboot works fine but using platforms create the same problem as pm-hibernate.
