 Posted: Fri Jul 15, 2005 10:08 pm Post subject: Software Suspend2 && Nvidia AGP? |
 |
|
Hi!
I got software suspend2 working quite easily but, as reported by other users,
it doesn't work with agp enabled and the nvidia driver.
On the other hand, somebody released a patch to the nvidia driver which should make
it work, or not..
The question is if it *is* possible to do hibernate+nvidia+agp?
As far as I understand it's not possible, can you confirm that?
Thanks for help!
Ps.:
I have no internet at home atm, so I can only answer some days later.. |

Is there any reason you need the agp (I'm guessing you mean the kernel's in-built agp)?
If it's just the nvidia-kernel you mean, I've had it working on all of the current nvidia drivers from portage (except 6629, which needed an additional patch to work).
Are you having problems resuming?

Hello!
Thanks for your reply 
I have AGP support enabled in the kernel and when I hibernate my PC from xorg
it starts dead on resume (weird graphics, keyboard dead..)
Exiting xorg before hibernating does the trick, but this sucks.
Now I've seen ppl patching the nvidia drivers to properly resume on some kind of
Powersaving signal, but you need to disable AGP for that and/or set NV_AGP in your
xorg.conf and all in all this got me really confused..
I need AGP for games of course, so I don#t want to do hibernating wo. agp/xorg support.
Again my question, is nvidia+hibernate+agp possible ?
Thanks again * |

Hi,
I use suspend to ram (STR) which works fine for me. I did not compile AGP support into the kernel (not even as a module) and use the nvidia AGP support instead set in xorg.conf:
My AGP is reported as on:
| Code: | root@raf>cat /proc/driver/nvidia/agp/status
Status: Enabled
Driver: NVIDIA
AGP Rate: 4x
Fast Writes: Enabled
SBA: Enabled |
BTW:The hibernate-script never worked for me. I ended up doing a bit of reading and writing one myself (which I have included at the end of this post). Basically I stop some of the services, unload all usb modules, and use acpi to sleep.
MY QUESTIONS:
1) When I resume my screen starts off grey and turns white (kinda scary), but when I switch to vc1 and right away back to vc7 everything is fine. I've been doing this for months but would like to fix this.
2) Any version of nvidia higher then 7174 does not allow me to wake up from STR. The screen just stays black and I have to power down. Any idea what has changed from 7174 upwards? Anyone have the same issue?
