Public bug reported:
Binary package hint: pm-utils
Unless I am missing something, it appears that the handling of this quick is
incomplete in Ubuntu 8.04, pm-utils 0.99.2-3ubuntu9.
In 20video, there is no attempt to perform the "vbetool vbestate save
>somefile" operation.
Then, in 99video, it uses: "vbetool vbestate restore
</var/lib/acpi-support/vbestate" which restores from the wrong place. I assume
we should be writing and reading these in /var/run, similar to the "vbemode"
handling.
While trying to fix, I copied these files to /etc/pm/sleep.d and
modified to work correctly. When running the Gutsy 2.6.22 kernel, my
fixes work correctly. While trying with the 2.6.24-17-386 kernel, my
machine still does not restore and pm-suspend.log shows that BOTH
scripts had run. According to the pm-utils doc, using the same file
name in /etc/pm/sleep.d as is in /usr/lib/pm-utils/sleep.d should cause
the /usr/lib version not to execute. In 2.6.22, I only see my
customized scripts in /etc/pm run, but in 2.6.24, the log shows that
BOTH have run.
I don't know how to submit a patch, but here is the code that I fixed
for VBESTATE_RESTORE:
in 20video, added this handling:
if [ "${DISPLAY_QUIRK_VBESTATE_RESTORE}" == "true" ]; then
vbe vbestate save > /var/run/vbestate
fi
in 99video, changed the VBESTATE_RESTORE to:
vbe vbestate restore < /var/run/vbestate
(instead of /var/lib/acpi-support...)
Hardware: Sharp GP22, SiS chipset, SiS M650 video.
