I've disabled SAVE_VBE_STATE, POST_VIDEO and USE_DPMS in /etc/default /acpi-support a week ago. Since then I didn't experience any failures to resume from S3 sleep, and also the suspend/resume process feels faster.
By the way, when I was debugging the suspend, I saved a typescript of sh -x /etc/acpi/sleep.sh. This bit looked very interesting: + . /etc/acpi/resume.d/15-video-post.sh + [ xtrue = xtrue ] + vbetool post + . /etc/acpi/resume.d/17-video-restore.sh + [ xtrue = xtrue ] + vbetool vbestate restore Function not supported + [ 3 != 3 ] + vbetool vgamode set 3 Function not supported Why does vbetool complain? -- Laptop sometimes fails to resume from ACPI S3 suspend https://bugs.launchpad.net/bugs/81722 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
