im running fedora 19kde on a new toshiba laptop 64 bit was originally installed with windows 8 which is gone now :). when my screen turns off it will not come back on until i reboot. like if i put it into hibernate mode or "sleep" mode or even if i just close the lid the screen will not re-start. i have the screen lock turned off and also when i close the lid i have it set to do nothing. any ideas?
