Summary: backlight doesn't come on after resume with i915 video
Product: Drivers
Version: 2.5
KernelVersion: 2.6.26-rc8
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI)
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
Latest working kernel version: n/a
Earliest failing kernel version: 2.6.26-rc6
Distribution: Debian (sid)
Hardware Environment: Thinkpad X40 (82852/855GM Integrated Graphics Device)
Software Environment: n/a
Problem Description:
After performing a suspend to RAM, my laptop's backlight does not come back on.
Pressing the brightness adjust keys on the laptop has no effect, neither does
prodding /sys/class/backlight/thinkpad_screen/brightness,
With 2.6.25 and earlier, the software tools to manage suspend would perform
quirks (S3 "bios" and "mode") which result in the backlight coming back on
properly.
I first noticed this because pm-utils (the software bit that handles suspend on
behalf of hal and gnome-power-manager etc.) performs a check for 2.6.26 and if
found, doesn't do userspace quirking, assuming that the kernel drivers handle
it all instead.
Steps to reproduce:
boot in single user mode
suspend
resume
