Do you want the computer to sleep when you close the lid? (I find this very annoying!) You can change it at System Settings > Power Management > Power Profiles > Performance (and others) > When laptop lid closed: Do nothing / Lock screen.

Now, the other issue is not recovering from sleep. Unfortunately this is not always easy to resolve. It usually means you have a component that is not responding correctly to the system power events and requires additional settings or even a new driver.

Does the problem even occur if you sleep via a menu command?
Have you loaded the proprietary driver for the nvidia card? Via K > Applications > System > Additional Drivers.

i did Applications > System > Additional Drivers. but the window is clear
i did just like you said and disable the sleep while closing the lid
thanks

OK, there may be a component or driver that needs to be explicitly powere3d off and resumed.

Do you have wireless? Bluetooth? Wireless drivers often seem to cause this.

It's not a complete answer but try this: disable networking (and bluetooth) from the notification area icons. Then sleep the computer from the K > Leave menu. Wait a few seconds and try to resume. Does it work?

I did as you said and turn off the wireless but it's still the same cant recover from sleep. i do have bluetooth but its also was turned off

You haven't told us what you have done to try and wake your PC from sleep. Are you pressing the power button?

hi...
im having the same problem..
actually mine is not by closing the lid, but its just any other way of sleep (manually putting on sleep or going to sleep after sometime to protect battery life)
as well as going to hibernate,
i suffer in wakening up, it gets stuck, nothing works on it (CTRL+ALT+DEL, CTRL+ALT+BACKSPACE, CTRL+ALT+F1-F7, pressing power button once)
and everytime i have to hold power button have a terrible shutdown and lose all the work!
im not sure whats happening but seems to me kubuntu cant handle any kind of going to idle and waking up... the reason for this idea is that anytime it dims the display after being idle for several minutes, upon waking up (typing or moving the mouse) it brightens the display with a very long delay. I have to work in a dim display for few minutes (!) for kubuntu to finally get it that she has to wake up!!

I must disagree. Here, on my HP laptop, running 12.04 w/KDE 4.8.1, I can 'lock' the system, shut the 'lid'. If manually locked, I hit any key and am prompted for my password, and when typed in and pressing the enter key, I'm presented with my desktop. If the lid is shut, the system sleeps/locks, whatever. When I open the lid, I am prompted for my password, and when typed in and pressing the enter key, I'm presented with my desktop.

then any ways I can find out what is actually wrong..?

We will need to know about your PC and the version of Kubuntu and KDE you are using.

My computer at least - a 2006 Dell Centrino Inspiron 630m, with the infamous 915 Graphics card, has a similar issue.

Sleeping (aka suspend to RAM) initially looks like it works - the system does go to sleep and the power light fades in and out. Pressing the power button brings back the desktop but then it instantly goes black and just shows the cursor. The only thing that works thereafter is REISUB. I have therefore given up trying to make it sleep.

Hibernate (aka suspend to disk) is a different game altogether. I ensured I have a swap partition at least the size of my RAM and that works OOTB.

well i have problems with both and my RAM is just 4GB and my swap is actually 10GB !
for wakening up, sometimes happens what happens to you (black screen with cursor) and sometimes if the screen saver was playing before, it gets stuck on screen saver picture...
the very interesting part is that, based on experience I found out that sometimes the login dialog is actually active, is just not shown on the stuck picture of screen saver; so having that, i just type the password and it logs in... but the problem is, out of 10 times, only 2 times that happens.. the rest of the times I have to give up since nothing happens!!

And the same thing happens when you hibernate too?

I had some problems with suspend (and hibernate) in earlier versions. I think the problems generally arise from specific hardware. (And the problems don't arise in Windows because, lo and behold, the manufacturer has had to go through lengthy testing and approval by Microsoft.)

I can't recall the specific solutions in my case, but check the following:
- Are there any errors shown in /var/log/pm-suspend.log?
- Are there any errors shown in /var/log/messages including the text PM?
- Does it work if you boot from GRUB with the additional kernel option acpi=off?
- Does it work if you boot from GRUB with the additional kernel option pcie_aspm=off?
