I just upgraded my Maverick to Natty 3 days ago. It's fun and good. I try to be familiar with Unity, but the Natty constantly freezes suddenly. I try another alternative, I use Ubuntu Classic instead of Unity, and at the end my computer continues freezing suddenly and it made me really angry, I can't do anything except of force my computer to shut down through the power button. My laptop is Compaq CQ20 windows & 32bit

do you have any propietary drivers installed? – Uri Herrera May 4 '11 at 4:57
of course, I already installed the drivers through "Additional Driver" at system menu – ok comp May 4 '11 at 5:01
most likely is that, are they nvidia or ati? uninstall them and keep the nouveou or radeonHD drivers a.k.a the open source one's – Uri Herrera May 4 '11 at 5:03

Add this to your repositories.

     deb natty main #xorg-edgers PPA                  
    deb-src natty main #xorg-edgers PPA

or in the terminal:

     sudo add-apt-repository ppa:ubuntu-x-swat/x-updates

or Open the Software Sources menu by going to Applications->Ubuntu Software Center, then selecting Edit->Software Sources. Choose the Other Software tab and click Add.


and then

     sudo apt-get update

see if it helps.

You advise a supposedly non-guru user to upgrade to non-default X ? I wouldn't recommend that. – Barafu Albino May 4 '11 at 8:22
it's not that hard.. clicking the ubuntu logo, and go to software sources and add the ppa.. it's pretty straight forward? – Uri Herrera May 4 '11 at 8:27
or opening a terminal and typing the ppa to add it – Uri Herrera May 4 '11 at 8:34
and why not? the present state the drivers he's using are causing that if he updates them he's most likely to get it fixed. – Uri Herrera May 4 '11 at 8:36
Xorg-edgers is not for the faint of heart - it's populated with automated builds of upstream development. There's no guarantee those packages will work at all. – RAOF May 4 '11 at 9:16

Besides Uri answer try this too: enable proposed updates in Software Sources, and update your system to 2.6.38-9 kernel. Maybe this helps.

thanks for your feedbacks, but I get confused of too many answers given, can you give me the straight forward answer? – ok comp May 6 '11 at 3:29

I have an HP MINI 210 and it freezes like yours, my issue? the wireless card!

the solution: blacklisting the following drivers:

blacklist rt2800pci
blacklist rt2800lib
blacklist rt2x00usb
blacklist rt2x00pci
blacklist rt2x00lib

(this should be appended to the file /etc/modprobe.d/blacklist.conf)

then restart and it should be working if this is your issue!

if this doesn't work, don't forget to remove those lines from the file.

good luck!
