This problem (Lenovo Thinkpad S1, Intel graphics) is still present for
me, and the VBlank fix in #12 did /not/ work.

show the screen (e.g. it is a lit, but black screen) on the normal
wake actions (open lid, press lenovo's
I also had this problem - not able to resume after sleep - on my Dell

Xorg NOUVEAU to NVIDIA's latast available driver.

Hi,
I am experiencing another version of this bug but I think it might be
related. When I resume after my computer has been asleep, the system
freezes up to 6 times. Each time lasts in about 30 seconds, then it
comes alive in a few seconds, and then another 30 seconds freeze.

Hi,
just to confirm that method mentioned in post #12 works and solved the issue.

Anyway perhaps it helps to find the root cause:

the machine sit
Same problem with me - HP Compaq 6710b, Intel integrated graphics card.
Started happening after I upgraded to Natty.
So, does #12 work? None of the people wrote back of it not working, so I
guess that might mean it does.

It didn't seemed to have worked for me.
Never had much problems with previous Ubuntu's, but with 11.04,
somethings were just not right. Maybe because they are transitioning
with the desktop environments. Anyhow, I got and installed Xubuntu, and
it's been smooth since, this issue doesn't happen.
Hi Lucky,
The Dell Optiplex I was experiencing this on is only has built-in Intel
GMA950 graphics so if it definitely is a graphics driver issue then it
might not be something limited exclusively to Nvidia drivers.

I am running natty with the same issue on a Lenovo Edge with built-in

Will try solution #12 now. If you don't hear back from me, it's solved.

I think this is a video card problem. Using nVidia geForce 8400 GS.
After suspending the computer and turning it on, the computer was
working (hard drive noises and num lock led in the keyboard was on but
the screen refused to response, just black screen).
No suggested keyboard combination
Hi all,
I too have this exact same problem after waking from Screensaver on
11.04 (Natty) on an old Dell Optiplex GX620 (P4 HT).
Until this issue is resolved a quicker and easier way of restarting
X-Windows (rather than logging into the console) is to re-enable the old
CTRL-ALT-Backspace
Just followed Patrickus' instructions for unchecking Sync to Vblank in
Compiz Config Manager (Post #12) so we'll see if that fixes things.
Many thanks for the suggestion PKC.

I was having the same problem with a Lenovo G560 and natty. Patrickus's
solution (#12) seems to have worked for me.
The screen would go to sleep, and then X would be unresponsive - except
the mouse would move. I could Ctrl-Alt-F1 into a terminal.
All programs were operative, just inaccessible.
I used sudo apt-get install compiz compizconfig-settings-manager, once
there I browsed to Compiz Config Manager / clicked on OpenGL / and
UNCHECK Sync to VBlank. These steps are what I took on my DELL
Inspirion 1525 running Ubuntu 11.04 Natty to resolve the freezing
problem I was getting when I

reboot is not necessary, a simple pkill -9 -u user-name on the console

Want to say that it still froze a couple of times after disabling compiz, but
it happens much less now, as before it was happening constantly.

Disabling compiz seems to have fixed the freezing.
There might be a shorter way to do this, but this is what I've done.:

Then on the blue icon that appears, right click, go to
