gnome-shell lockup while trying to resume after idling the laptop for a while

[hadrons123]

my dell gnome shell doesnt resume , every 2 out of 5-6 times when i try to resume shell after idling.
I dont switch off the laptop at night and in the morning,the screen shows only user name and time on the screen.the shell just hangs.sometimes it lets me into alt+f2 or f3 and i could kill the gnome-shell and get back,but sometimes i need to kill xorg to get back at gnome-shell.

does any one of you have the same problem?
i m not sure if its the hardware or its gnome-shell, i never had issues with f14 or ubuntu 11.04.
this is my lspci output...

I'm on my desktop system at the moment so I can't post my lspci output. I will do so later when I am on that machine.

I also have experienced this, but found that when I mouse about the screen, just above center, the arrow changes to the I beam shape. I figure that this is the input box for my password to unlock the screen. I usually click there, then enter my password and it usually will take me back to the desktop after a delay of several seconds.

I would also like to see this fixed. It does not occur on my desktop machine with Nvidia graphics, but does occur on my netbook with AMD/ATI graphics.

Its a pretty annoying bug, everything else works fine for me.
when i was using ubuntu unity for 2 months i felt too bored.But unity worked like charm.Lot of times I used to think to get back to ubuntu 11.04.But i don't have the same feel(maybe emotional) of fedora there.That's why i couldn't go ubuntu way!

but.....
blame the ATIs.ATI really sucks.
I didnt have a chance to use nvidia in linux yet.
Does linux support in nvidia card is really that good as people talk about it?.

I am being forced by Gnome Shell's misbehavior to change to XFCE. I was kind of liking some of the things about Gnome Shell, but when it took most of my class lecture to get my system booted and running so that I could take notes, I couldn't take it any more. it kept locking up tight (frozen mouse pointer, unresponsive keyboard, only hard reboot worked. That was unacceptable. I cannot lose valuable note-taking time playing around with a recalcitrant desktop manager. So, it is time to make a change.

I have XFCE running now. It is similar to the old Gnome 2. I have compositing turned on, so I have some effects such as being able to set transparency of background windows and transparency while moving, etc. It doesn't have the eye candy of my old Fedora 14 Gnome 2 with Compiz, but it is okay. It seems to be much faster and, so far, much more stable. Perhaps when Gnome 3.2 comes out things will be different, but I need things to work NOW.

after you said to me , i tried XFCE a bit. it feels like a whole different beast.
i would rather stick with gnome areas,than experiment on XFCE.moving to XFCE means learning some steps in it,for which I would happily switch to ubuntu.i love gnome so much.
