I also have loads of boot issues on my W520. I am using Oneiric though
because breaking my working environment in gnome is not an option and
not what I get paid for on my day job ;-)
* halt from the command line halts but does not power off
* The W520 has multiple video modes but only one of them
powers up the VGA connector. When using that, boot is
a russian roulette. It is not unusual for the kernel to
lock up twice before I finally get a boot. A couple
times I had to pull the battery to get the BIOS and
linus kernel to start playing nice again.
* I have on occasion seen the sleep problem. It happens
in particular if I walk away from the machine and it
is on a vt rather than gnome; but it has on occasion
happened in gnome as well.
I have gotten into the habit of always shutting down when I
travel from the dual screens at home to the dual screens at
work because linux gets tied up in its knickers if I do,
if it wakes up at all.
Things do work better if I am on the factory BIOS graphics setting,
which I use when travelling, but as I said, in that mode the VGA
port is turned off.
Since I have no intention of upgrading from Oneiric at this
time, I have not reported these issues. I have just gritted
my teeth, sworn the occasional general curse and got on with
work.
