Default powermizer is dead after resume on GT240

Hi!

Powermizer works well on my GA-790XTA-UD4 board with GT240 card until the first suspend to disk. But after resume it locks in the middle performance level (405MHz/324MHZ). No lowest and no maximum performace available any more.

This problem exists with my custom compiled .36/37-rc3 kernels and my distros .33 kernel also, and both tuxonice and default kernel suspend to disk.

I did not find any workaround for this, try to choose the Prefer Maximum Mode in nvidia-settings and try to lock the performance level to maximum or minimum level in the xorg.conf with the RegistryDwords option, but it works only until the first resume, so it makes no difference.

Is there anybody with the same problem, or it is excepted to work well?

The attached bugreport log is made after resume.

Thanks
Akos

I have the same problem. I have a Palit card with 512 MB of GDDR5 and it gets stuck to the middle level after resume.

Same problem here on a GTS360M. Logging out and back into the x-server makes it function properly again though this kind of defeats the purpose of suspending...

Tested with all versions of the 260.* series drivers and x-servers 1.7.2 + 1.9.2 on slackware with kernels 2.6.33.4 + 2.6.35.7 but the problem remains.

This bug is not fixed in the new 260.19.29 driver. Any hope left?

It should not be so hard for nvidia to make a working power management, the open source radeon driver is a lot better in this case. You can change the performance level using /sys interface as you want, and dynpm is much more sane and useful than powermisery.

I didn't notice it before, but I have the same problem with a GT240 (DDR5) from XFX.
Before the suspend to RAM, the PowerMizer section in nvidia-settings shows the mode in use is the maximum one (level 2, 550/1700/1340Mhz), and after the resume it's stuck in the middle level (1, 405/324/810).
As others have said, restarting X is a workaround, but very inconvenient.
Using 260.19.29 driver, 1.8.0 server and 2.6.34 kernel (OpenSUSE 11.3 x86_64).
