When I put the the Ubuntu laptop to sleep (meaning I close the screen shut. It seems to work if I go to system shutdown -> sleep but still testing it) (I am using Ubuntu 10.04 and it is on an Presario X1000), when it wakes up, the screen has all these white and black noise signals across it and I have to restart.

How do I fix this?

could you try it with 9.10 live CD then 10.10 live CD, but upgraded VIDEO DRIVERS?! Write the results here, I want to compare distros. –  B. Roland Dec 17 '10 at 17:46
    
+1 on Video Drivers. What video card do you have? –  madmaze Dec 17 '10 at 20:57
    
Does switching to VT#1 and back to VT#7 (press ctrl-alt-f1 then ctrl-alt-f7) help at all? I would recommend filing a bug against linux (the kernel package) in launchpad using the command 'ubuntu-bug linux'. –  Andy Dec 18 '10 at 0:09
    
Hi, it doesn't work switching... how can I figure out what video drivers I am using? –  roguecartel Dec 20 '10 at 19:43

I had this issue - I tried a load of things and eventually the thing which fixed it for me was reinstalling. :/

check swap space of your system

sudo fdisk -l

find this kind of line

/dev/sda6            3796        3919      995998+  82  Linux swap / Solaris

you need at least 1GB swap memory for hibernate(sleep)
