Since support for 8.04 LTS will be ending soon, I decided to move up to 10.04 LTS. On my old Thinkpad A20m laptop, the install went well, and everything seemed to work except the middle trackpoint button. Fixed that easily by editing a conf file.
Then I began to notice some problems; all power management options (suspend, idle timers, etc) have no effect. I checked the startup logs and it seems that ACPI was not loading due to my aged bios (yes it's the newest version available). I tried using acpi=force in the boot options, and viola: power management is working. But that made two other problems crop up.
Problem 1: [Edit: solved]
Problem 2: Since using acpi=force, the laptop runs so hot it sometimes gets sluggish and locks up. I tried installing "thinkfan" from the ubuntu repositories to have some way of easily changing the fan behavior(which I believe relies on ACPI in some fashion). No luck there. ACPI seems to not see my fan at all, and it only kicks on when the bios high temp failsafe is tripped.
Any suggestions greatly appreciated! I should also mention I am using Xubuntu (for the lighter desktop). I'm still kind of an Ubuntu-noob, so I wasn't sure what other info to post. I would be happy to provide any other information which could help diagnose the problem.
