Ubuntu 10.04

It's the holiday season and that means OS upgrades.
I put the Ubuntu 10.10 CD in my home desktop and
tried to boot. It didn't even come up. I wonder if this
is the problem ESR mentioned. I put 10.10 on my two
grandchildren's laptops and didn't have any trouble.

I retreat back to 10.04. OK, boots fine. I'm a little
disappointed it doesn't detect my RAID but I know
how to do that manually.

It detects that I need a proprietary graphics driver
and downloads that... it figures out my USB wireless
device... a simple

mdadm -A /dev/md0

brings the RAID back up.

Wireless networking is unusably slow... there are
brief spikes of activity separated by long stretches with
no traffic flowing. I spent a couple of hours on this googling
and searching the forums. This magical incantation (I
wound up putting it in /etc/rc.local) fixed the problem:

sudo iwconfig wlan0 power off

See this thread.

Problem with hibernate using the 'Shut Down' applet
from the Gnome panel. Hibernation appears to work,
but resume from hibernate doesn't... system comes up
as from a cold reboot, but with networking disabled.
Problem is discussed at great length in bug 499940
and bug 577916, the latter of which appears to be still
open. None of the fixes described other than the
following workaround worked for me.

Workaround: I tried installing the 'hibernate' package
and running /usr/sbin/hibernate from the command line
(as root)... that seems to be working.

Slight bug in evince, see bug 572434. Fixed with

touch $HOME/.gnome2/evince/last_settings

I didn't need to do anything special to get Java and Flash
plugins installed into Mozilla, even running 64 bit. Nice.

It took me about a week to notice this but it seems the
distribution no longer includes the Lightning (calendar)
plugin for Mozilla Thunderbird. Just installing the
plugin from Tools->Add-ons didn't work. There was
some kind of incompatibility with 64-bit Thunderbird.
I was able to get it working by following this thread.

Update: my hibernate 'workaround' isn't really working.
This is keeping me from upgrading on my work box
where I use hibernate constantly switching back and
forth from Linux to Windows and I need this to be
fast and reliable. The last couple of times I tried
hibernate, when I went to resume I just wound up back
at the login screen.
