Okay, a few weeks ago I blogged about a script that could autogenerate a fdi file for HAL that could create the required video_adapter_pm methods and properties needed to suspend and resume your videocard on suspend and hibernate.

So, if you are one of a few people that are running a very recent (CVS less than a few months old) HAL and the new pm-utils (the one from freedesktop.org rather than redhat), and have to set odd kernel command lines or hacky commands to get your machine to work please can you give my script a whirl.

The idea is for technical people to send me autogenerated fdi files that are matched to their hardware, which are then be merged into upstream hal. This means on the next HAL release more systems just work out of the box without new users having to google and add oddball options gleaned from some random post of a bloke that has a similar laptop.

So, if you know you have to set S3_MODE or you have to add dpms suspend calls at the end of your custom suspend script, can you please try pm-utils and my script. The script probably won't be much use if you don't know what the cause your suspend problem is, although you could use it for that.

Feedback, as always, welcome.

Subject: Same problem with nvidia card I think
Seems like I have similar problem with my NVIDIA card. It does not awake correctly when I hybernate. Well I'm not quite sure of the problem but I can't get the display. I remember it worked once on my desktop. But not working anymore, I'm using last HAL from FC5 I think. Do you think that's related? How can I investigate this? (baris NOSPAM teamforce.name.tr)

Thanks Richard. I had to use s3_mode on my laptop too, otherwise no cake...
