Slackware 13.1 installed clean on a new ThinkPad Edge (version 13 inch with AMD Processor and ATI graphics).

I can get most of what I want working fine except for suspend and resume. I read somewhere that I should be using generic rather than huge kernel, so I have done that and scrapped ATI proprietary driver in case that was causing problems, but nothing so far has allowed me to suspend and resume with pm-suspend, acpitool suspend or with KDE suspend command. In all cases the screen blanks and the single ThinkPad red LED goes from on to blinking, but nothing seems to wake the machine up again.

I had both suspend and hibernate working fine with Slack 13.1 on an older Lenovo laptop and ubuntu users report on their forums that this laptop does suspend and resume "out of the box" so I feel it must be possible.

Any ideas ?

Thanks

Try appending to the kernel at boot and see what happens...

Hello,

At first I would try to suspend/hibernate in the text-mode (# init 3) to see, if it's Xorg graphics driver related. Then I would start removing kernel modules prior to suspending (wifi driver, ethernet driver, ...).

Regards, Daniel.

@corp769 : Thanks for that advice - almost solved the problem. If I add the boot-time kernel parameters as you suggest *and also* include --quirk-s3-bios and --quirk-s3-mode on the command line with pm-suspend, I get a complete suspend-restore cycle.

@dangazda ; I was indeed testing as you suggested - from the console. But having solved the problem there I have now tested by typing the command from a terminal in a KDE session and find it works there as well.

I have yet to test the KDE "suspend function", but I think I can set the status of this thread to "Solved".

Awesome, glad to hear it worked!
