Has anyone observed this suspend to ram bug?
 
On the newer set of drivers (including the latest stable) whenever I resume from suspend, I notice that google chrome is slower in scrolling. I notice this very clearly since I use a smooth scrolling extension and it just doesn't work right after suspend. The workaround I know is just to log out, rmmod nvidia driver in init 3, then return and everything is fine. Is this a known bug, and if so, is there another way to configure s2r to prevent it?

I experience this too. It will sometimes also self correct after another suspend/resume cycle.

There are occasional threads about something being slower or not accelerated any more after suspend. IIRC, the last one a few weeks back was about compiz getting slower (or opengl?). Not sure.

Anyway, you might find some more info on that buried in the forum.

Yes, I've observed this as well, but on the 195.X drivers (Dell E6510, NVS 3100M). I reported an Ubuntu bug here: https://bugs.launchpad.net/ubuntu/+s...ux/+bug/671932
But I eventually closed it as invalid, since I gave up trying figure out what was going on. Sometimes things would be visibly slower after resume from suspend.

Disabling all hyper-threading logical processors before suspending seems to work around the issue for me. Might be some kernel issue, might be some nvidia driver issue, might be some crap ACPI/BIOS issue..

I looked, couldn't find anything specific. I'm not seeing a difference in opengl so only basic 2d might be affected somehow.

Also, as someone else mentioned hyperthreading. I disabled it but in my case it made no difference.
