Suse Linux Enterprise Desktop 10 (SLED 10) works out of the box:  video, networking, trackpad with scrolling, suspend to disk.

My machine is a Thinkpad T41p, '''model 2373-GGS'''.

Things that I needed to tweak to make them work:
* Suspend to RAM

== Suspend to RAM ==

Suspend to RAM (actually, resuming) '''does not work''' if you have the [[Hidden Protected Area]] (HPA) enabled in the BIOS (see the section "SectorIdNotFound disk errors when laptop is resumed" in the [[Problems with ACPI suspend-to-ram | list of problems]]).  This is because of a [http://bugzilla.kernel.org/show_bug.cgi?id=6840 kernel bug], which makes the kernel not re-read the hard disk's HPA parameters when resuming from suspend.

I had to '''disable the Hidden Protected Area in the BIOS''', and then I installed SLED 10.  After that, I had to add

  SUSPEND2RAM_ACPI_SLEEP="1"

to <tt>/etc/powersave/sleep</tt>.  After that, suspend to RAM worked correctly.

(Doing the above in SLED 10 is the same as putting <tt>acpi_sleep=s3_bios</tt> in the kernel command line in GRUB, but the kernel in SLED 10 allows this to be set at runtime - see [http://en.opensuse.org/S2ram the S2ram page on the openSUSE wiki].)

I am using the free ATI Radeon driver that comes with xorg-x11.  I don't know or care if the proprietary drivers also work when suspending.

== Suspend when the lid closes or with Fn-F4 ==

I had to tweak some options in YaST's Power Management module.  Go to '''Power management settings''', click the '''Other settings...''' drop-down, and select '''ACPI Settings'''.  In the next dialog, change '''Sleep Button''' and '''Laptop Lid Closing''' to '''Suspend to RAM'''.
