Bug Description

On my laptop (Dell latitude D800, with NVIDIA GeForce 5650), the suspend (to
disk and to RAM) did not work out of the box.
The POST_VIDEO=true option need to be commented.

This is the output of the dmidecode command.

Here it is.

Is this using the binary nvidia driver, or the standard nv one?

The nvidia driver.

Matthew Garrett (mjg59) wrote :

If you use the nv driver, does it resume without POST_VIDEO being set?

As far as I remember, I never used the nv driver.
At install, the display was not working and the solution I found was to install
the nvidia driver to make it work.
Sorry, I don't have time these days to test the nv driver.

Hi Frederic,

Thanks for your report and providing the dmidecode data. It'd like to whitelist this and need to know if the "POST_VIDEO" is binary-nvidia specific.

Could you please test this if you still have access to the laptop; It should just require a quick edit to:


and changing the 'nvidia' to 'nv'. Testing Suspend to RAM and then changing it back with a second reboot.

Many Thanks,

Hi Paul,

I recently reinstalled entirely Breezy.
You can find some details on the installation here:

I indeed tested the nv driver, and it does not need to set the POST_VIDEO flag at false.
This is really nvidia specific.

Thank you for your work, Frederic

Is this still a problem? If not, please feel free to close this bug.

It is still a problem, but only with the proprietary nvidia driver.
I don't know ubuntu policy for bugs specific to this nvidia driver.

Having POST_VIDEO=true also stops resume working on a T60p (FireGL 5200) with the fglrx driver. This is driver 8.37.6 in gutsy Tribe 2.

The same system with the vesa driver suspends/resumes fine with POST_VIDEO=true

I can confirm that POST_VIDEO=true stops resume working on nvidia driver in edgy.

I have the same problem, on a completely different system - hibernation worked automatically but for resume from suspend I needed to comment that line too.

This is with a fresh Feisty install on a Toshiba M400, and my video driver is i810.

Sorry, the above confirmation of the bug may not be correct - I have just found that even with that line commented, resume doesn't work consistently (even though it did for the first time after I commented it!), so the problem may in actuality be caused by something unrelated.
