Nvidia and software suspend 2

Maranza · n00b Joined: 25 Jun 2004 Posts: 34

I'm trying to make this software suspend thing work, it looks very interesting. basically it's working: if i kill x and unload the nvidia and emu10k1 modules manually, resuming works and i can load them back into a fully working operating system. But i wouldn't get much of a speed increase by leaving X out of the suspension/resume cycle. Also X is loaded through xdm (kdm really, but here in gentoo the xdm service handles all), and the hibernate script can't shut it down properly: if i put xdm as a service to restart in hibernate.conf and blacklist the nvidia kernel module, on resuming it freezes on the nvidia logo. Anyone had a similar problem? Anyway, i've found a few solutions for the problem:
1. the case PM_SET_WAKEUP: hack looks very dirty to me. according to the wiki, it has to be inserted after line 3677 in nv.c, but i'm splitting up a function declaration here! i tried anyway, but i've got syntax errors of course.
2. i found another patch on the forums that might work.. but this one requires NvAgp to be set to 0, which means disabling agp support. I don't play 3d games, i think the most agp-aware application that i run is xcompmgr.. will i experience slowdowns without agp?

I'm currently using swsup2 with nvidia (with X and composite enabled).
Answers are in the swsup FAQ Section 4 Compatibility issues (parts 6 & 7) : http://softwaresuspend.berlios.de/FAQ-4.html#ss4.6.

To make it works, you have to use nvagp (nvidia agp support) by disabling agpgart in your kernel config.
Don't forget to re-emerge nvidia-kernel once you have your new kernel compiled.
After reboot, you've got to have something like this :

ok, i've cut off the agpgart support from the kernel and added nvagp... it's working nicely

i've still got a couple of problems tough:
1. is the image invalidated after each resume? i mean, can i safely try to resume an image even if i haven't suspended last time (swsusp2 will then skip resuming)?
2. the console is blank, would help using a framebuffer console?
3. after a few seconds, the video output goes crazy: the video is shifted of about 40% the lenght of my monitor. The part that would go out of the screen appears on the other side of the screen. Switching to the (blank) console and back to X solves the problem, but it's annoying nonetheless..
anyway, thank you :-)

I got a huge problem with swsuspend2 in X.

I followed what you said :
- I de-activated agpgart and re-emerged nvidia to use the NvAGP driver
- I configure xorg.conf as well
- I uncommented the unload nvidia module in the blacklisted-modules file
- I de-activated FW and SBA in the /etc/modules.d/nvidia

But still my computer can't store the image and freeze, while my screen has been shut down. So my monitor is off but my computer stays on undefinitely ; when i reboot (with reset button), it does a usual boot.

nb : it happens only in X ; when i'm still in console, the hibernate works well.

Good news, I have finally managed to get suspend2 works with nvidia module.

I have tried a couple of setup, but here's the last one which made it possible.

First, I did it with this kernel version :

I can't get suspend2 working with nvidia (geforce4 mx). After resume I always see blackscreen, the machine (it's desktop pc, not laptop) seems to be hanged. I do not have agpgart in kernel/module. I do not use framebuffer. "SwitchToTextMode yes" does not help. I dunno how to fix it ;>

no4b,
I was having similar problems where I could suspend in text mode but X would hang with a black screen on resume. I found out today that I had to disable AGP entirely. ie: in xorg.conf add

Hmm same problem here, is there an other solution for this? I'd like to use suspend2 + nvidia+ intel agpgart.

did the format of the hibernate script config files change?

I don't seem to have things the way that you have

I have it working now.
I just issue the hibernate command and then push the power button for it to wake up.

is it possible to make it wake up when I hit the keyboard or move the mouse.

Idealy I would like it to WOL, but that is not a big issue.

thanks for this thread.

I have run glxgears and I get 19 FPS with a GF3 ti200

does that seem really low?

I wanted to thank all of you for this post because I finally got this hibernate working (it was the NvAgp to be set to 0 that did the trick).
And therefore my question: any news about this? Will we always have to remove the AGP to hibernate?

I would like to re-iterate the fact that to get a nvidia chip to suspend with X that you need to have agpgart not installed. Or that is what I believed, it seems that having NvAGP set to 0 has the same effect, or not loading agpgart.

I would like to disagree with yoyo about setting NvAGP to 3. I told Thesee to set it to 1, instead of 3, and his system was them able to hibernate properly, and still have agp functionality.

The issue is that "3" tries to load agpgart first before attempting to use nvidia's agp. So if agpgart is on the system, then it will be loaded and then it won't hibernate. Using "1" skips that and ensures that nvidia's agp is loaded. Which is what allows us to continue.

And I should also recap that nvidia's binary driver (the later the better) is what is being used here, I don't think people should be using the NV driver instead of Nvidia's with hibernation. I'm not saying it won't work, I'm just saying that the results aren't as prevalent.

Just wanted to let everyone know that I got it working fine with ~amd64 keywords and the following setup:

Linux 2.6.22-kamikaze6 #4 PREEMPT Wed Sep 5 19:41:25 EDT 2007 x86_64 AMD Athlon(tm) 64 Processor 3400+ AuthenticAMD GNU/Linux
VGA compatible controller: nVidia Corporation NV34 [GeForce FX 5200] (rev a1) w/ x11-drivers/nvidia-drivers-100.14.11

Here is my hibernate.conf:

FBSplash on
FBSplashTheme suspend2
ProcSetting full_pageset2 1
ProcSetting extra_pages_allowance 0
UnloadBlacklistedModules yes
LoadModules auto
GentooModulesAutoload yes
SwitchToTextMode yes
UseDummyXServer yes

(Note: I also have the framebuffer splash on and it works with hibernate)

and in xorg.conf I have:

Option "NvAGP" "1"

Hope this helps someone...
