I have set up my laptop to always suspend ("sleep" in KDE) when the lid is closed. However, when I open the lid, everything is working except for the screen, which is black. I can interact with the machine using SSH or SFTP from another machine, and the keyboard seems to be alive, lighting up when I press keys, but I cannot see any output. The brightness level has been set to full. I have to hold down the power button to force it to close down and then restart it to regain the screen.

Under Fedora 19, the screen always came back properly when resuming, but the keyboard was sometimes dead,and I needed to close the lid and wait a while before trying again, and eventually it always worked properly.

May be driver problem, try upgrading.

Well I haven't installed any drivers explicitly and am not sure what I would need to do. I do a "yum update" every couple of days.

See if the problem you have is not this?

Thanks for your suggestion. I checked out that report but it is a different problem. I tried doing a sysctl suspend, and it suspended the machine as expected. Pressing the power button to resume brought back lights to the keyboard but the screen remained black, just as it does when I close and reopen the lid. Also, I never see the cursor on the black screen.

you may try change vt , with ctrl + alt + F2 and back to X with ctrl + alt + F1 , may could refresh screen .

we need much more information what dmesg says after wake up, and /var/log/Xorg.0.log , to see what video card do you have . but better is open a bug report with all this information that I asked into Bugzilla , you may look here [1] and click on Report a new bug against this package in Fedora, or if you think is kde use [2] and maybe should also check xorg-x11-drv-(intel|ati|etc)

Thanks very much for your advice. I have tried ctrl+alt+F2 and ctrl+alt+F1 but that did not work.

I have submitted a formal bug. I really appreciate the advice on what additional information is required.
