RE: Radeon PM Support

Does this addon patch (over the Ole's original patch) help?

This works with Radeon 9000M and frame buffer for me. This 
should also help any other graphics drivers which doesn't
implement their own suspend resume functions.

I just hope that this video reposting won't break any of the
already working systems :).

Thanks,
Venki

Hi,

quoted

Intel's new graphics chipset probably. Owners of Acer 

Travelmate 60X told

quoted

me that the video doesn't come back. But in the these case 

the whole system

quoted

locked up on resume, so we can't tell if the video resume works.

it also happends for the 80x series (in my case 801Lcib) with 
ATI Technologies 
Inc Radeon R250 Lf [Radeon Mobility 9000] using the framebuffer. 
"echo 3 > /proc/acpi/sleep" and "echo 4 > /proc/acpi/sleep" 
doesn't work 
because video doesn't come back as described by Stefan. The 
only reaction is 
the fan which runs like hell and doesn't stop. Same thing with 
pmdisk and 
suspend to disk ("echo -n disk > /sys/power/state"). All 
tested with recent 
kernels 2.6.7-2.6.8-rc3 .
But with swsusp2 as the suspend to disk system  ("echo 

quoted

/proc/swsusp/activate" ) on a 2.6.7 kernel the video card 

recovers!?! 
I don't know much about the whole thing and why swsusp2 can 
(help) recover(s) 
the video card but perhaps it may help you.
