Hi Frank, thanks!! The link you posted worked for me also (so far so good anyway!). I changed to network boot as recommended. In my case I had had the Acer set to boot from USB first because I had installed Ubuntu from USB media and had not changed it since there is no optical drive. I tried setting it to boot from the HD and that seems to work better although I think it did lock up once (but not nearly as much as with USB set as the boot drive). Strange though because with no USB inserted it just bypasses the USB and goes to the HD boot. Not sure why it makes a difference but clearly it does make a difference.
Also, I found this post in the Linux Mint forums where a user states the same problem of having to boot into Windows first then back into Ubuntu Linux which apparently is another symptom of the same fundamental problem. Here is that linux mint post (which has some other links in it in addition which might also be helpful to anyone running into this issue). http://forums.linuxmint.com/viewtopic.php?f=46&t=88072 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1016094 Title: System freeze unless booted after Windows has run To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1016094/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
