Re: 2D rendering slowdown on suspend (NVIDIA NVS 140M, Thinkpad R61)
I have been having this slowdown issue too. The strange thing is that it depends on kernel version.
I'm using 2.6.19 with suspend2 2.2.9 and it works fine with latest drivers (and even previous ones).
When using newer kernel (.22 for sure, I think it is .20 - but I'm not sure if I remember it correctly) the setup works fine with the latest driver - but after suspend, the GFX card is slowed down.
To sum it up (both tested now with nvidia drivers 100.14.23)
2.6.19 with suspend2 2.2.19 works fine after resume (no hacks needed)
2.6.22 with suspend2 2.2.10 has gfx card slowdown after resume
So the reason for this behaviour may as well lay in kernel itself, not NVIDIA drivers.
