Help with S3 on an Acer Travelmate c110

Help with S3 on an Acer Travelmate c110

[Adam Olsen]

Hello,

I was wondering if any of you could help me with suspend to ram on a 
travelmate c110.  I'm running kernel 2.6.10 on Hoary.

It seems I can suspend, and sort of resume.   The machine seems to 
resume, but the display does not come back on.  I can issue commands 
like reboot, etc at the terminal I suspended from.  I cannot get the 
display to come back on whether or not I suspend from within X or just a 
plain terminal.

Any ideas?

Adam

Read Documentation/power/video.txt in the kernel's source directory. This 
should help you ;-)

Thanks for the response.  I followed the documentation, but none of the 
methods worked.  I did, however, find something in someone's blog 
concerning a Travelmate c300 that mentioned a utility called video_post. 
  This works - you have to switch to a VT and back to X to get it to 
start working, but this is scriptable with chvt.

video_post wasn't easy to find via google - there are lots of posts 
about it, but most links are broken... a forum post finally led me to 
this link: http://bugzilla.kernel.org/show_bug.cgi?id=3670 and download 
"attachment.cgi", which is actually a .tar.gz package.  I guess this is 
just an FYI for anyone who might come accross the archive searching for 
Travelmate c110.

Thanks,

Adam

Hrmm, I never tried this because I thought it was for Radeon only :(

Yup, and thanks again.

This method should be listed there. Well, it's not listed under this name, but 
there's a link to my(again outdated) Acer TM 800 howto which lists a few 
simmilar tools

Can you provide documentation patch?

For now I did:

...but better solution would be welcome.

How's this?  I changed the Travelmate C300 entry because the 
documentation I found to get the C110 working was actually for the C300 
- it just happened to work for the C110 too 
(http://www.umich2.com/files/2004/12/linux_on_the_ac.html).

Hmm. There /should/ be no difference between video_post and vbetool
post.

I see at least one: video_post allow architectures that are not i386.

Ah, yes, that's true. The Xorg people told me that vm86 was preferable
to x86emu on x86, but that doesn't help a great deal for amd64. I'll
port it at some stage.
