Occasionally my pc wont resume from suspend (to ram) properly.

Instead of the expected "resume" the pc just does a normal boot.

My biggest problem is that I have no clue where to look for that error. I am missing a point to start, especially because it happens not very often and I can't reproduce it.

I'm running on 64 bit natty.

My PC:

  • AMD Phenom II X4 955BE
  • Gigabyte GA-770TA-UD3
  • ATI Radeon HD 5770

I believe this is essentially a bug and should be reported directly to Launchpad. –  Marc Boisvert Sep 22 '11 at 14:48
    
To answer the second part of the question: help.ubuntu.com/community/ReportingBugs has an instruction for filing bugs. Doing so might help improve Ubuntu. –  bacon Sep 23 '11 at 12:13
    
It may have something to do with the GPU. I recently switched from ATI to Nvidia and since then it never happened again. –  imbaer Sep 25 '11 at 9:40
    
It's not a problem related to GPU or CPU... I'm using an Asus A45V with Intel & Nvidia in it... and sometimes this bug pops up, completely randommely... I'm using Ubuntu 12.04.2 by the way. –  user142575 Mar 26 '13 at 14:15

this solved my problem, but my computer did the reboot all the time instead of resuming, not sometimes y hope this helps

this worked for mi before i install ati drivers Edit the file /etc/default/grub (as root)

Change the line with:

GRUB_CMDLINE_LINUX=""

to:

GRUB_CMDLINE_LINUX="acpi_sleep=nonvs"

run update-grub (as root)

and this ohter one worked just fine after installing the ati drivers

"I've solved a similar issue (reboot on resume) with a Sony Vaio VGN-FW51ZF by changing the last line of the file /etc/acpi/sleep.sh from pm-suspend to pm-suspend --quirk-radeon-off (guess it was a problem related with ATI proprietary drivers)."

so thanks for those tips and i hope this save you some time

from Suspend fails (reboot on resume) and no hibernate option
