Comment 36 for bug 133677

This issue is not fixed for me with hardy.

I have this bug for long time with ubuntu, and i newer had a time to look what can i do, but now:

it worked for me with s2ram ... so what s2ram do and ubuntu-suspend not...

according to:
http://en.opensuse.org/S2ram
"Machines with Intel graphics chipsets often work with "s2ram -f -a3", even when using vesafb framebuffer."

    -f, --force: force suspending, even on unknown machines. -- not important
    -a, --acpi_sleep: set the acpi_sleep parameter before suspend <--- !!! important
                      1=s3_bios, 2=s3_mode, 3=both

"Since kernel 2.6.16, the acpi_sleep parameter can be set during runtime (no reboot needed) in /proc/sys/kernel/acpi_video_flags, with "1" for s3_bios, "2" for s3_mode and "3" for both. More information about those hacks can be found in the kernel-source (usually installed in /usr/src/linux) in the file Documentation/power/video.txt."

So ubuntu-suspend do not set acpi_video_flags !!! It should be implemented before it hardy geting stable.

=============!!! try this !!! ================

echo 3 > /proc/sys/kernel/acpi_video_flags
/etc/acpi/sleep.sh force

===========!!! it working for me !!! ============
