[Bug 417599] Re: pm-suspend with quirks does not restore backlight anymore
I too have a wonderfull Dell c400 and the info in this bug helped me get
suspend working. Thanks. However, my config of Ubuntu seems a bit
different so the instructions that work for me are listed below. Note
that the splash boot option caused the cosole video to core dump in
combination with nomodeset so I removed it.
Fix for Ubuntu 9.10:
1a) In /etc/default/grub
add i915.modeset=0 nomodeset to GRUB_CMDLINE_LINUX_DEFAULTcat. This disables
the new kernel mode-setting (KMS):
GRUB_CMDLINE_LINUX_DEFAULT=quiet nomodeset
or
GRUB_CMDLINE_LINUX_DEFAULT=quiet i915.modeset=0
1b) Save and run update-grub.
2. In /usr/lib/pm-utils/sleep.d/98smart-kernel-video
add return 1 in have have_smart_intel:
have_smart_intel()
{
# Not sure which option cuses blank screen after suspend restore but
# disabling this section works.
return 1
3) Save and reboot.

[Bug 417599] Re: pm-suspend with quirks does not restore backlight anymore
Wait -- that's incomplete. Originally I deleted all the non-Intel sections, and that worked. Looking for a solution easier for others to follow, I tried just removing the quirks lines, and thought it worked, but it didn't. My solution, in short: 1. In /boot/grub/menu.lst add i915.modeset=0 nomodeset to the defoptions line. This disables the new kernel mode-setting (KMS): # defoptions=quiet splash i915.modeset=0 nomodeset 1b) Save and run update-grub. 2. In /usr/lib/pm-utils/sleep.d/98smart-kernel-video delete all references to quirk options your machine needs to suspend. In my case, three quirks are in the section have_smart_intel: --quirk-dpms-on --quirk-vbe-post --quirk-vbestate-restore and two are in the section remove_all_video_quirks: --quirk-s3-bios --quirk-s3-mode 3) Save and reboot. -- pm-suspend with quirks does not restore backlight anymore https://bugs.launchpad.net/bugs/417599 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I had the same problem (Karmic Alpha 4 on a Thinkpad X40 here), and I
worked around the problem by adding the following line
return 1
in /usr/lib/pm-utils/sleep.d/98smart-kernel-video :
# Test to see if the kernel has a video driver that is smart enough to
# handle quirks without external assistance. If it is, remove the quirks.
have_kms()
{
return 1
# if we are running with a KMS-enabled video driver, we should not
# attempt to run any quirks
[ -d /sys/class/drm/card0/device/graphics/fb0 ] || return 1
remove_all_video_quirks
add_parameters --quirk-no-chvt
}
- it forces using quirks even with KMS enabled.
It worked for me, but I'm not by any mean knowledgeable in all that
stuff...
