Re: 2D rendering slowdown on suspend (NVIDIA NVS 140M, Thinkpad R61)
I am also having the slowdown after resume problem on a Dell D630.
Graphics card: NVIDIA GPU Quadro NVS 135M (G86GL)
Driver: NVIDIA GLX Module 100.14.19 Wed Sep 12 14:48:02 PDT 2007
I don't have vbetool installed and tried suspending via
echo mem > /sys/power/state
but it was still slow upon resume.
It does run at normal speed again if I restart X. (This is a little difficult because quitting X simply turns the screen black with a cursor at the upper left, but there is no prompt and you can't type anything).
Running nvidia-settings -q all before and after suspend to ram, there is only one difference:
diff /tmp/before /tmp/after
< Attribute 'GPUCurrentClockFreqs' (D630:0.0): 400,594.
> Attribute 'GPUCurrentClockFreqs' (D630:0.0): 275,301.
But I don't think that's the problem, because the slowdown is several orders of magnitude.
I would sure appreciate any help on this!
