dell latitude C800 - apm/acpi


I'm having immense troubles setting up either ACPI or APM on my latitude. I've been reading up a lot on the subject, though. Also, the bios doesn't seem to be too buggy. When recompiling it with iasl, I only get a warning (also as a sidenote, I don't know how to make the kernel use my newly compiled DSDT, if that would be necessary - I'm running kernel 2.6.10).

Anyway, so I was just wondering if anyone has the same model of laptop as I do, and have properly set up either APM or ACPI. If so, do you have any tips and tricks?

Edit: Also; perhaps I should mention that I have created the s2d partition with dell's own tool: mks2d. When I run apm -S, nothing happens. Running apm -s puts the computer to suspend mode but locks when resuming. The keyboard and screen work though. If using ACPI, state 4 (echo 4 > /proc/acpi/sleep OR acpitool -S) gives no response (just like apm -S), and state 3 suspends but messes the screen on resume. Everything is done without X running.

I have a C800. It runs APM. I don't think ACPI is possible with a C800. I use swsusp to suspend to disk, which is configured and ready to go in SuSE kernels. Suspend to RAM has not worked since the switch to the X11 distribution. When you get to the point where you are ready to try suspending with X running, things work best if you disable DRI by commenting out that section in the X configuration.

thanks for the reply...

I'm gonna try suspend-to-disk later. I think I did try it a while back without too much success. My problem with suspend-to-ram, though, doesn't seem to be X. As I mentioned, I get this problem without X running at all. Which bios and kernel are you running? I'm running the latest bios, A23.
