Problem Description: 
Running GNU/Linux without starting (console ony) X i can dont get video after a susend to ram, if im on X and press suspend the system will come back

Steps to reproduce:
echo 3 > /proc.....
press power button


One thing to notice is that if i do startx the video is NOT restored, but checking the logs the notebook LCD is not detected by the nvidia module instead it show info about CRT and TV...
i do have a working terminal and SSH acces however, only no video...

Note: i had the problem before compiling the nvidia driver....

i dont know what info to provide....

Well, you can try s2ram (http://en.opensuse.org/s2ram) with various combinations of options.

Do I understand correctly that the box resumes successfully when it's suspended from under X, but it doesn't when it's suspended from a console?
Comment 2 Luis Diaz 2008-10-15 14:45:51 UTC 
I did not try to suspend from console with X running...just without even running X

does s2ram anything special?

OK, but I understand that you tried from under X and the resume worked?

> does s2ram anything special?

It can, depending on the options you pass to it.

it seems that this is just the know S3 video issue.
what if you startx and switch back to console, and then try to suspend to ram in console? I think that should also work, right?
then, do you know what's the graphics driver for nvidia in Linux?
what if you load these modules manually in console mode and try suspend to ram again?
Comment 5 Luis Diaz 2008-11-05 03:18:27 UTC 
so, u mean that i should startx and go back to console without closing X ?

Xorg is using nvidia (binary) driver, but i noticed the problem even before compiling it
Suspend from console does NOT work, even tough the module is loaded or not.
in console im using vesa, but i also used vga=normal without any luck
Comment 6 Zhang Rui 2008-12-08 19:35:18 UTC 
then you should try s2ram per Rafael's suggestion. :)
