Since my last upgrade (for upgraded packages see attached part of dpkg.log)
the backlight is off after resume from suspend to ram. As descibed in the
original bug report, "pm-suspend" shows this behaviour (as does suspending
from KDE for me), while "pm-suspend --quirk-s3-bios" does not.
I went back to the old version of hal-info I used before the upgrade
(20081219-1), but I did not get back normal behaviour with backlight on after
resume. I also attached a patch that comments out the disabling of quirks,
which make resuming working again with the current version (20090202-1).
Please add the patch to the next version.
My laptop seems to be identical to the bug reporter's. It is a Thinkpad X40,
to be more precise:
$ lshal |grep system.hardware.product
system.hardware.product = '23711CU' (string)
$ lshal |grep system.hardware.version
system.hardware.version = 'ThinkPad X40' (string)
$ lshal |grep system.firmware.version
system.firmware.version = '1UETD2WW (2.07 )' (string)
I am happy to provide more information or test other possible solutions.
Regards,
Sten
