I have an Acer Aspire One with a dual core AMD 1GHZ processor and 2GB of ram.
I have Ubuntu 11.10 installed (full install, not wubi). I had this problem when I was using wubi, and I thought a full install would fix it but most of the time when I boot up ubuntu, after about 15 seconds on the desktop, it freezes, neither the mouse does not move nor clicking does not work, key combinations don't work. I am a relative n00b to linux but is there any way to fix this?
Try this: connect the Internet with wired cable first, then start your computer. If every thing is good, then the most probably problem is the Ethernet card and the wireless card share the same ID. If this is the case, you simply make PCI Lan disabled in BIOS.
It sounds like you might be experiencing a bug where Acer Aspire One's tend to freeze while trying to connect to a wireless network. A simple way to test it out (and to fix it if this is the problem) is to set "Network Boot" as the top priority in your BIOS's boot order. You can do this by pressing F2 to enter your BIOS settings. Navigate to the "Boot" setting and move "Network Boot" to a higher position than your hard drive (Preferably the top).
If the freezing still happens, you can undo this by moving network boot back to a lower priority.

I was able to trace a similar problem to the rtkit-daemon, or perhaps
one of the processes that use it (the last entry in the syslog
always had rtkit in it).
After reading the man page for the rtkit-daemon, I tried adding the line
RLIMIT_RTTIME=1
to the file
/usr/share/dbus_1/system_services/org.freedesktop.Realtime
Worked, to my great surprise. The 1 above was just an arbitrary guess.
