Installing Mandriva Linux on a ThinkPad T20
Mandriva 2005 LE
Mandriva controls suspend/resume preferences through the file /etc/sysconfig/suspend. It is a well-commented text file. Here are two options I set that seemed to help make sound continue working after a suspend on the T20:
RESTORE_SOUND="yes" SOUND_MODULES="sb uart401 sound soundcore maestro cs4281 snd-cs46xx"
I'm not sure if all the sound modules in this list are necessary. I added snd-cs46xx to the list because I knew it was the one I was using.
From the Mandrake Control Center, I configured one specific Thinkpad-specific option for the sound driver. I entered the "Hardware" area and then selected the sound card and clicked "Configure Module". One of the options is labeled simply "thinkpad". I set it to "1".
Screen Locking after Suspend
My screen always came back locked after I suspended, and I couldn't figure out how to turn that off at first. That preference is also in /etc/sysconfig/suspend and is named LOCK_XFREE.
I set it to "no", but can still lock the screen if I want by using the Klaptop "Lock & Suspend..." option
