Re: Can't resume from suspend
Toz ](*,) it was killing me what the hell was causing it. You were bang on from the start TLP was the issue. I had to fight this to see what the problem was it was really bugging me. Without installing TLP I can't reproduce the problem. As soon as I install TLP BAM!!! it starts happening. The only problem is I don't know how to report the bug or is it specific for my hardware......
I did email the PPA owner as there was no option to report a bug on his page. I can live without the extra 2 hours battery life. Going to look into some other power management options.
Re: Can't resume from suspend
Are you using the proprietary fglrx driver or the open source radeon one? The proprietary drivers often give better power management performance.
Also, what is the model number of your laptop? Is it one of those hybrid laptops that has both an intel and amd graphics card? This will help identify the video card(s):
Code:
sudo lspci- vnn | grep -A15 VGA
Re: Can't resume from suspend
Open source I do get slightly longer with the fglrx driver. I have smoother experience with the open source driver. But my fan almost never stops spinning even if its idle for over an hour.... It does stop frequently using the fglrx driver thus giving me slightly better battery life. fglrx maybe 2hrs max open source 1hr 30 mins max and using the TLP I was getting 3 1/2 - 4 hours.
Re: Can't resume from suspend
Sorry it isn't hybrid laptop either it has Radeon HD 7670M dedicated graphics.

What model number is the laptop?

Re: Can't resume from suspend
Can you try some kernel boot parameters to see if you get better power performance? See the "Kernel Boot Parameters" link in my signature for more information on how. I would suggest trying, one at a time, the following:
acpi_osi=
Code:
GRUB_CMDLINE_LINUX="acpi_osi="
acpi_osi=Linux
Code:
GRUB_CMDLINE_LINUX="acpi_osi=Linux"
acpi_osi="!Windows 2012"
Code:
GRUB_CMDLINE_LINUX="acpi_osi=\"!Windows 2012\""
Re: Can't resume from suspend
Can I add them like this:
Code:
GRUB_CMDLINE_LINUX="acpi_osi= quiet splash radeon.audio=1"
I need the radeon.audio=1 for my HDMI sound to work with the radeon open source driver.
Re: Can't resume from suspend
You could, but the general convention is to add new parameters to the GRUB_CMDLINE_LINUX line (leaving the originals on the GRUB_CMDLINE_LINUX_DEFAULT line) like this:
Code:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX="radeon.audio=1 acpi_osi="
Re: Can't resume from suspend
Hi,
the official way to file a bug report against TLP is now mentioned in the documentation: Issue Tracker.
Anyway, i found your post here. Does the suspend problem occur on ac and battery power or only in one of the cases?
Please show the complete output of (on battery):
