Bugzilla Bug 363441: Dell Latitude D830 Notebook X-Display remains dim after suspend/resume

Description of problem:

S3 sleep causes X-display on notebook to remain dim (too dim to properly read)
after resume. FN-key light controls can't be used any longer (no reaction).
Hibernate will not show this effect . it will actually elevate this problem.
Tried several hal-qirks but no result.

If BIOS seleceted light control via light sensor is used situation with
backlight is better, however controls remain unusable after suspend/resume.

Kernel upgrade from 2.6.22.9-91.fc7 to 2.6.23.1-10.fc7 causes keyboard to fail
in many occasions after suspend/resume causing a full stop (no X-server kill is
possible via keyboard).

System uses intel video driver (i810 & 915resol. will not work).

Version-Release number of selected component (if applicable):

libsmbios bin and libs are installed Version 0.13.10-1.fc7.

How reproducible:

Backlight dim and unusable FN Keys to control backlight: 100%
Keyboard fail after resume: about 60%

Steps to Reproduce:
1. suspend notebook, either on panel using power manager or using pm-suspend
2. resume notebook (either powerswitch or opening the lid
  
Actual results:

backlight stays dim, dellLcdBrightness will not work setting values, Fn-Keys not
working. Sometimes keyboard frozen (only FN-Esc will put the system to suspend
mode again).

Expected results:

backlight at same level as before suspending or at least controllable.
dellLcdBrightness should be able to control backlight. Fn-Keys are expected to
work. Frozen keyboard should never occur.

Additional info:

Several notebooks show this behavior, even if installed with an i386 F7 system
(eg. running x64_86 is not the problem).

Would some quirk
(http://people.freedesktop.org/~hughsient/quirk/quirk-suspend-index.html) help?
What I mean is, that you could try to go through
http://people.freedesktop.org/~hughsient/quirk/quirk-suspend-debug.html and play
with pm-suspend so long as it will be working for you.

Please, let us know whether some quirk helps.

I just found out that my D620 needs the following quirks:

pm-suspend --quirk-vbe-post --quirk-vbemode-restore

These two quirks fix: https://bugzilla.redhat.com/show_bug.cgi?id=358631
 and: https://bugzilla.redhat.com/show_bug.cgi?id=358671

Possibly these would help here?

Please, see https://bugzilla.redhat.com/show_bug.cgi?id=358631#c9 and continue
accordingly in this bug as well.

I've already played days with pm-suspend and different setups of quirks in hal.
Using /usr/share/hal/fdi/policy/10osvendor/10-dell-laptop-brightness.fdi and
/usr/share/hal/fdi/information/10freedesktop/20-video-quirk-pm-dell.fdi and the
modes described by Michael. I did also try power_management.quirk.no_fb,
power_management.quirk.s3_bios, power_management.quirk.s3_mode, the latter both
together with appropriate change to the kernel. No success.

64bit debugging is unfortunately not possible (as described on
qirk-suspend-debug homepage).

AFAIK D620 and D830 have _different_ video hardware (945 vs 965 chipsets).
Quirks working to D620 need not neccessarily work.

OK, I give up -- could you please attach to this bug as separate uncompressed
attachments your /etc/X11/xorg.conf and /var/log/Xorg.0.log and I will pass this
bug to developers to sort it out.

Created an attachment (id=250011) [edit]
The xorg.conf

Created an attachment (id=250021) [edit]
Xorg.0.log

Just contains hibernates.

Attached both requested files. I will capture another Xorg.0.log for with just
one suspend in it. This one has several hibernates in it.

Thank you for help!

I just came back to my D830. First I saw lots of updates including new kernel
2.6.23.1-21.fc7. I yum'ed them and tried suspending. While the suspend through
PowerManager (2.18.3) did not let the system resume correctly (see above) it did
do the suspend using pm-suspend --quirk-vbe-post --quirk-vbemode-restore
as described by Michael. I don't overview what's effectively new, but a fully up
to date Fedora 7 will work using this. I think this can be used to program hal.

I'm satified. This issue can be closed by now.

Thank you all, Aron
