Default Re: 2D rendering slowdown on suspend (NVIDIA NVS 140M, Thinkpad R61)

I'm looking for alternatives that don't have the slowdown on resume problem while waiting for NVIDIA to fix the problem.

Has anyone tried the xf86-video-nv 2.1.3 driver in Xorg 7.3? I read somewhere that it includes support for the NVS 140M. I can live with 2-D only for now to get suspend working.

You can always go back to VESA (which I ended up doing, sadly...).

Thanks Alex - I've been considering switching to the vesa driver as a last resort. I assume that suspend/resume works fine with it. Are you having any trouble with graphics intensive 2-D video applications? I use my laptop to watch TV with a Hauppauge HVR-950 and Slingplayer (under Wine).

I've got both s2ram and s2disk working with uswsusp using vesa, but i have not tested video playback... I have enough computers around the house for that task. ATM I'm only using this laptop for browsing and book reading, so vesa is fine. As an added benefit, you also get control of brightness (another *hint-hint* directed at NVidia).

P.S. Forgot to mention...
When using nvidia driver, s2ram -f is all you need, whereas with vesa you need to call it with -f -a 3
Also, it looks like I can watch videos as well

On my Dell XPS m1330 (8600M GS), the new 100.14.19 seems to have fixed the slowdown-on-resume problem. It's not explicitly in the changelog but it does mention geforce8 slowdowns. Oh well - at least things are working now :-)

The GeForce 8 performance problem referred to in the release highlights is a different one, but 100.14.19 does have another fix for slowdown problems after suspend/resume cycles.

I have an 8400M GS (Dell Vostro 1400) and the new drivers exhibit the exact same problem for me. Can you post your /etc/default/acpi-support and /etc/X11/xorg.conf?

Whats with brightness control? It isn't fixed yet for my nvs 140m, will that be part of the next driver?
It's very annoying to switch to a console in order to change brightness levels of the panel..

Please see 100.14.19's README for power management related additions. One common problem with several distributions is that their NVIDIA specific pm-suspend scripts re-POST the NVIDIA graphics device when resuming (using `vbetool`). Please make sure no such scripts are run. If in doubt, check if suspending directly via /sys/power/state works better.

I'm seeing good results with using "s2ram -f" to suspend.
However, it appears brightness control is still broken.

GFX Speed is fine now after resume on my Thinkpad R61.
Brightness control is still not working though.

Not havoing to restart X after resume is more important though.
So thanks alot for that fix.

The lack of brightness control can be workarounded by switching
to a text console, adjust it there and then switch back to X (vt7).
Of course that workaround doesn't mean it the issue can be ignored.
