Talk:How to make ACPI work
- I have tried the referred patch (Suspend to RAM) with the latest stable kernel (22.214.171.124): Reboot after wakeup.
Has anyone managed to get this working with a T22? The BIOS is upgraded, but it _never_ wakes up from sleep. Neither lid nor pwr button are noticed by the system.
--Are you in suspend2ram? This works fine for me. I think you have to enable it in BIOS.
Sound-after-suspend not working with Mandriva 2006
With Mandriva 2006, suspend/resume works with ACPI, but sound quits working. This happens with the T20 and T22. The recommended Mandriva trick of setting "RESTORE_SOUND=yes" in the "suspend" script doesn't solve this. Other suggestions? - MarkStosberg email@example.com
I had 2 different issues: - with my X21 I had to unload the alsa modules before suspend. - with my x23 I have to change the mixer settings to get it working again.
(I hope it will help)
I have found out that if I use cifs to mount Samba shares, I get lots of problems with suspend/hibernate (the cifsd breaks the shutdown process). Maybe it would be good to warn about this.
