Description Harald Koenig 2005-08-29 11:46:06 UTC

APM suspend to ram doesn't work anymore *never has been a problem up to 9.3).
suspend works, but the system dies at resume.  suspend/resume from
text mode console vc1 doesn't work either.

text mode shows up but still is garbled. CAPS_LOCK key does't work (no LED)
but ALT-SYSRQ is still working.

I've tried acpi suspend to (never tried before! ACPI was claimed to be broken
on this very old ontebook) and it didn't work either.

Do you use the savagefb kernel module?
Does removing this module helps?

yes, probably a duplicate of bug #113607

sorry for those 4 attachments, they should have gone to bug #113810
which I just replied to.  no idea how I managed to change the big id underneath :-(

sorry for the delay!

pasting my mail reply from 29 Aug 2005 14:25:36....
did I mention that I hate bugzilla ?? :-((

correct.  I just found report #113296 and wrote a comment there:

renaming the savagefb and rebooting fixed my APM problem.
now resume after "apm -s" works again.  thanks!!

but why does this module get loaded at all ??  I'm booting with
"vga=normal" because I'd like to stay with 80x25 plain text mode...

bug #113607 is a bug - these modules should not be loaded (they also should not
kill suspend, but this is another story).

BTW i'd recommend using
 "powersave -m" (APM Standby)
 "powersave -u" (APM Suspend)
 "powersave -U" (swsusp suspend to disk)
over "apm -s" and friends. Those should work (they just trigger an event in the
kernel which in turn triggers powersaved) but this is mostly untested.

since using ACPI, I can't use "apm -s" anymore:

        harald:~ # apm -s
        No APM support in kernel

I've seen your recommendation before, but how can/shall apm work with ACPI
enabled (and thus APM disabled) ?

up to 9.3 I only could use APM -- ACPI didn't work.  so I had no choice,
I only could use APM and "apm -s"...


thanks!

powersave always worked with APM and ACPI. Thats the whole purpose of powersaved
- giving a unified solution / frontendd.
