Description of problem:
I'm using Fedora 8 and I want to hibernate.
Without nvidia-96xx-kmod and related RPMS it works fine.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. yum install kmod-nvidia-96xx
2. try to hibernate
With nvidia-96xx-kmod (kmod-nvidia-96xx ?) the hibernate part seems no different than before, but when I try to resume the resume cycle seems to complete, the laptop display backlight comes on and then the caps-lock light stops responding to key presses.
The hard disk light indicates activity but nothing is displayed and even the laptop power-off button doesn't power the system down - holding it down for 5 seconds powers off the machine.
Expected hibernation behavior
With the kernel command line option vga=791 in grub, the hibernate cycle doesn't complete - the machine doesn't seem to get to the saving ram to disk part - it just freezes.
I checked upstream with nvidia and found http://www.nvnews.net/vbulletin/showthread.php?t=58498
It gave me the hint to set NvAGP to "0" in xorg.conf - it worked, but as this turns off use of the AGP port, 3D animation was choppy.
I then tried Option NvAGP "1" and that worked too. Problem solved!
I haven't tried vga=791 again in case it breaks things.
So it looks like the problem lies with the Kernel's AGP drivers.
For what it's worth the kernel AGP driver seemed faster.
Also when the resume cycle completed, the "science" screensaver doesn't show the desktop background - I guess it wasn't saved - a minor quibble.
The reason why the kernels AGP is faster is because NvAGP wasn't enabled
# cat /proc/driver/nvidia/agp/status
revealed that it was disabled.
Adding "agp=off" to the kernel boot parameter enables it - hibernate still works.
The science screen-saver still occasionally misbehaves.
Enabling compiz-fusion wreaks havoc on resume from suspend - it crashed KDE.
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '8'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 8's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 8 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
