LCD fails to recover after lid closure on Dell Latitude D520
 

I am running Slackware 12.2 on my Dell Latitude D520, using KDE as my desktop, whenever I close the lid, the LCD fails to come back on after I open it back up. I have searched the forums, but did not find anything related to slackware.

Have you added your users to the 'power' group?

Is it suspending when you close the lid?

What video card?

For NVidia, I recently discovered that version 180.29 of the official NVidia driver fixes this issue.

Yes, I am added to the power group, it is an intel 945GM video chip set, it does not suspend, it just goes black, I can get it to recover by pressing ctrl, alt, del and logging out of KDE (blindly I might add) it brings me to the console and I can start x again and it works fine.

For suspend when I close the lid on my laptop, I actually have a line added to my /etc/acpi/acpi_handler.sh under power)
I have KDE settings that do not enable suspend to ram.
This allows me to suspend to ram whether I am using KDE or any other window manager.
