    Ciao Everyone!


    actually same problem here, from what I could work out is a permission issue... if you restart, go to Recovery HDD and simply apply "repair permissions" everything works out perectly.... till the next reboot!


    another thing (out of topic I know, but I am here to complain... let's do it properly ) it's the annoying printing problem on Canon printers from Preview and Textedit... and again from what I gathered on the web it's a permission related problem...


    let's hope they will patch it soon!


    See ya

    Same thing here. MBP 15" i7 2.66Ghz 8GB RAM - Mid 2010


    Freezes all the times (Beach ball of death), and App Store takes forever to load.


    I use Tuxera NTFS driver (that says in their website that is compatible with Lion).


    Everytime I try to copy lots of data to my external 500GB NTFS drive I have this freeze.


    I tried to look at system.log but nothing seems to help.


    Is there anyone else with the same problem?

    Also getting the freezing login screen...


    2010 MBP 15inch.

    8GM RAM

    Intel I7


    boot the mac while plugged in... login works just fine

    boot the mac on low battery (<10%).... freezes 3/3 times for me.


    boot the mac while plugged in...wait till the login screen comes up... confirm it is working fine by clicking and typing... then UNPLUG the mac... instant freeze...and i have to hard-reboot.

    I have exactly the same issue with my 15" MBP - mine has the option to switch graphics (better battery life or better performance). I recently changes to "better performance" and got the freeze straight away. Had it maybe 1/3 of the time after that. I've switched back to "better battery life" and haven't had a freeze yet. Could be coincidence but thought I'd share it.

    I'm having thesame problem, after my upgrade to OS X Lion, my laptop takes time to boot and some of the programs is runing slow, now iMovies is saying it will take 27 hours to complete the video, It was using 4 hours to do before.


    Please Apple you should look into it.

    I have a MB Pro mid 2010.  I have reintalled OS X 3 times, once  being a clean install with no luck.  My problem is similar.  If I do not login within 4 to 8 seconds when the login screen appears, my system locks up.  About 50% of the time I will get the "You need to restart your computer by holding down the power button."  However, if I login within the above mentioned time frame, my system appears to be stable, although I have had a 3 kernel panics when using Aperture and Safari at the smae time.  I am working with a Senior llevel support and they want me to do another clean install and not restore any of my applications from a time-machine backup.  I will do this but I don't think this will change anything because even booting into safe-mode my system behaves the same way.

    Hey Folks,


    actually I found a solution, at least for my peculiar problem...


    as I thought it was related to permissions, as you know Lion changed sensibly security policy, permissions included.


    Some workaround to have Canon printer working was to add an Admin user to Library, and allow this user to read&write. After that at each restart the Login screen froze, rebooting and repairing permissions you will see a list of what is "out of place" take note of it and go to see its permissions.


    There is not much to do, simply open infos for the folder and save as you will find them (they are rectifyied by Repair permissions utility so they are correct) and apply the same permissions to all the contents.


    At the next reboot Lion will in the end accept the permissions status as they are and you will be able to log wihtout incidents.


    Another solution is to apply some Onyx or other software to repair permissions, guess it will work too.


    Maybe it will not be the solution for you all, but should do for everyone suffering of permission issues,

    @ jsm & Jmac:


    i've never liked the idea of an upgrade or restore (coming from a long time on windows - always have problems with those) so when lion came out, i manually backed up docs and files to a flash drive and did a clean install of lion.... then re-installed all of my apps from the app-store, and then restored my documents & files manually... i am still having the login screen issue...

    I have found that unchecking "Automatic Graphic Switching" has solved my freezing-up issue at login.  So I don't think it's related to any of my apps and therefore I will hold off on doing a clean install for now.
