[linux-laptop] re: compaq 2110us and suspend to ram

[John H.]

In reply to pavel's last comments:

Ok, I was reading video.txt.
I have a radeon 320m/mobility u1, but I didn't have access to my
keyboard after "resume," either, not just video.  I am using
video=radeon:ywrap,mtrr,font.... in grub.conf, so i should be using
radeonfb(but i can not use fb if necessary).I wanted to ask,
quickly...

you said that with your patch, it will not resume properly anyway, so,
at this point, can I really even test the various options in
video.txt?  I mean, regardless of what grub.conf parameters I specify
that are mentioned in video.txt, as long as your patch is what I am
booting off of, it shouldn't work anyway, right?

compaq 2110us and
fc4
athlon xp processor

EVEN with acpid not running, I get a power off when I try to resume
from suspend to ram by hitting an acpid button, which I am desperately
trying to get working.  It works fine in XP.

The only way I can prevent poweroff is using this modifcation to
wakeup.S which was provided by pavlov, but it obviously does not allow
correct resume.  It does, however, show something.

So what does this mean?  Obviously this patch is going to prevent a
successful resume, but when I use it, the all the lights return to
normal but I get no key usage nor video usage on resume.  If I do NOT
use these modifications, pressing any acpi button powers off the
computer, even if acpid is stopped.
