When i try to reactivate my notebook after it went to standby or suspend mode the screen stays black. The only solution i have is to reboot the notebook by pressing the shutdown button. Anyone has any idea to fix the problem?

Hangs of this nature can have a number of causes which appear similarly. Is the backlight on for the screen (is it lit up in the dark)? Are you able to switch virtual terminals to VT-1 (press ctrl-alt-F1), if this works you will see a black screen with a textual login prompt. Does the machine respond on the network (ping <machinename>.local from another system)? – Andy Nov 18 '10 at 10:09
I also have this problem with the screen going black after suspend or resume on an Asus Eee PC 1201N. – jr0cket Nov 18 '10 at 11:19
I am using Ubuntu 10.10, upgraded from 10.04 using the update manager. Suspend and hibernate worked previously on Ubuntu 10.04. The 1201N laptop seems to suspend and hibernate successfully and when I press the power button to return from suspend or hibernate is seems to work correctly (disk drive activity), however the screen simply does not display. If I drop down to a terminal window (Alt-F1), still nothing is displayed. If I do a Ctrl-Alt-Del keyboard combo then the laptop will reboot as normal and the display is resumed – jr0cket Nov 18 '10 at 11:27
