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... -- 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
