this one is driving me nuts. My HP dv7 laptop isn't resuming from suspend and hybernate. On suspend - resume it leaves me with a black screen. On hibernate it succesfully loads the images and then it hangs....

I searched through internet and tried serveral things, but nothing seems to work for this HP dv7 on Ubuntu 12.04. With 11.10 it didn't work either.

  • Nothing happens. I can't login. The console doesn't respond only restarting the system helps. The /var/log/pm-suspend.log doesn't show any failures.... Where can I find the resume log??

I do not know if it helped the original post but it didn't for me.

I have Ubuntu 12.04 on a Toshiba Z830. I remember when I installed it like 2 weeks ago suspend was not a problem. Then I wanted it to be able to hibernate and installed Tuxonice. It didn't work and removed it but I would say that since then I cannot suspend anymore. Besides when I do uname -a I get:

Linux ubuntu 3.2.0-26-generic-tuxonice #41~ppa1-Ubuntu SMP Sat Jun 30 08:47:46 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

The kernel is still named after tuxonice.

I am not sure this belongs to this thread but definitely the solution given above does not help (I found an update from him in Ubuntu Forums that also doesn't work for me).

I posted my problem somewhere else and it got solved:

I wonder if the original post had some kernel issue too and the link above may be useful for him too.

    I guess the question is hardware specific. Yours was a Toshiba and the problem probably caused by installing Tuxonice. The OP has a HP.

I had the same problems with 12.04 LTS on HP Pavilion dv7. After hours of research and anger I read some article about nvidia drivers. I finally installed nvidia-current package via Synaptic which is not installed by default, restarted and everything works fine.
