Laptop wont resume from sleep

[sky5564]

So i have installed 12.04 on my acer aspire 5253-bz893 laptop, Everything is working except the sleep feature, It will go into sleep but it will not come out of sleep, I just get a black screen.

Anyone else have this problem?

Sleep worked fine on the live cd but after i installed it no longer works.

I get this sometimes on my Sony Vaio. It's probably ACPI related. As it's only occasional I can live with it.

Got any recommendations for me? I could probably fix it myself if someone could just tell me where to look.

No idea where to start really. ACPI deals with your pc's hardware and settings, as I understand it. It's not an area I would want to get in to. The down side could be disastrous.
Can you manage without sleep? I think I would.

You can keep the system fully updated. That way updates in the future may yield a result.

If you have an intel video card you can try the following

sudo gedit /etc/rc.local
setpci -s 00:02.0 F4.B=00

Before you try the above command let's see what your video card is

lspci | grep VGA

Here is mine

terry@terry-eMachines-E725:~$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 09)

Wow thanks, When i searched the forum nothing came up lol.

It seems this is a driver issue and can probably be solved by replacing the proprietary fglrx driver with an opensource one.

Thanks again.
