i had a similar problem, and this helped. your posts made me realize it was connected to the wireless, cos when i was plugged in it didnt do it, and as soon as i unpluged and it started connecting to my local router it froze again. it didnt at first after install, and after a few updates and installing a couple hundred programs i was worried i had a bunch of conflicts from other programs....... like compiz and cairo, but everything seems to be fine, i have the acer 722 netbook, and that link above fixed it for me. ive been working on this system too long to reinstall like i did the last time!!!!!! hope it helps! i love linux! and ubuntu is freedom for your computer! ive been using it for over 5 years, and love it. there are bugs and crashes here and there, but every time you learn how to fix it or figure something out it goes into the next distro.... not that tho, but the community. i saw your post which made me realize something was connecting my freezes with the wireless, and that helped me find this fix. it worked for me, only tested it for about an hour but i didnt boot win7 and it seems stabilized. let me know if this helps, and if i encounter this again i will work with you on a better fix. --and check out the other stuff on that link, some of it seems very helpful! :) -- 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
