Description peter czanik 2005-08-28 10:33:29 UTC

Comming back from suspend-to-disk fails. It worked probably up to changing back
to a graphical screen, at least I could see a "loading high mem" message, and
then the monitor changed mode, and then turned off. The keyboard froze as well,
so only a hard reset helped. ReiserFS was repairing itself with 3-4 screenfull
of logs.

The strange thing is, that it worked fine in beta 1 & 2.

I'd need kernel messages printed during suspend/resume....

Could you try taking kernel from beta2 and see if it works with beta3?

Comment 4 peter czanik 2005-08-29 17:55:00 UTC

Sorry, I found the reason. I use the binary nVidia driver, and did not read
documentation ( /usr/share/doc/packages/powersave/README.suspend-NVidia ).

Comment 5 Forgotten User ZhJd0F0L3x 2005-08-29 19:02:21 UTC

so does it work if you use the open source nv driver?
Or does it work if you follow the steps in README.suspend-NVidia?
Or does it not work at all but you blame the nvidia driver :-) ?

Comment 6 peter czanik 2005-08-29 19:43:00 UTC

It was just a blame :-)
But now I have tried ťhe README.suspend-NVidia, and seems, that my blame was
right. When I follow the instructions, suspend-to-disk works.
I had to make only a slight change apart from the documentation: I had nothing
related to agp in /etc/sysconfig/hardware. intel-agp loaded always automaticly
(even if I started just runlevel 3), so I removed it from /lib/modules/...
How do I change to the opensource nv driver?

Comment 7 peter czanik 2005-08-29 19:47:09 UTC

Suspend to RAM works fine as well after this change. After 11 years of Linux I
still have to learn again, that reading documentation helps a lot :-)

Comment 8 Forgotten User ZhJd0F0L3x 2005-08-29 20:02:39 UTC

regarding the opensource driver: just change the driver to "nv", like in:

| Section "Device"
|   BoardName    "GeForce FX Go5600"
|   BusID        "1:0:0"
|   Driver       "nv"
|   Identifier   "Device[0]"
|   VendorName   "NVidia"
| EndSection

(i did not get around to installing the binary driver to test it yet ;-)

I have to check who loads intel-agp, this may be a bug. Christian, any insight
on this? intel-agp is loaded although nothing agp like is in
/etc/sysconfig/hardware. This makes my documentation (README.suspend-NVidia)
look bad ;-) Do we have to use /etc/hotplug/blacklist again for such stuff?

Comment 9 Forgotten User ZhJd0F0L3x 2005-08-29 20:46:55 UTC

BTW: for suspend to ram, can you add a short report to bug #103930, describing
what you had to do to make it work (regarding the NVidia driver, mentioning the
README is enough :-) and on which system this is? Thanks!

Comment 10 Christian Zoz 2005-08-29 21:29:46 UTC

The only remaining way to avoid to load a module is /etc/hotplug/blacklist.
(maybe we'll move it to /etc/modprobe.d/blacklist, since modprobe can do this
itself in between).

If you want to learn, why and when a certain module is loaded, read
README.Logging in docdir of newest udev package from STABLE (package for beta4).

Comment 11 Forgotten User ZhJd0F0L3x 2005-08-29 21:42:28 UTC

ok, so after one release of /etc/sysconfig/hardware-controlled module loading,
we are back to full hotplug. Good to know ;-)

When will /etc/modprobe.d/blacklist go into production? I'll wait until then
with my documentation. And do i have to put in intel-agp or intel_agp or both?

Comment 12 peter czanik 2005-09-02 20:49:06 UTC

I see, I got a 'needinfo'. But what info?

Comment 13 Forgotten User ZhJd0F0L3x 2005-09-03 20:53:17 UTC

i was not sure what worked for you. But after reading your reply with open eyes,
i got it :-) Thanks.
