[ltp] Fedora 11, resume unreliable on X40

Thu, 23 Jul 2009 16:21:33 -0600

Thanks for the pointer, but this did not work for me.  I may have a
different problem, however. In my case the laptop comes back, but with
a very dark display. Sometimes I can see the faint prompt and can type
commands, meaning the OS is alive. The laptop will also suspend and
resume again, but the dark screen persists.

Seems like a problem with the display intensity, or the display not
being turned back on.

Christos.
