After some update( I don't do regular reboot after update, so I can't
trace which one triggers this), I got my Dell screen constantly fall into
powersave mode directly. I had tried with windows, which got no problem at
all.
The reason may lies in the driver? For now, if I use the ati driver,
the I can boot into the system, but after some time, the screen would
directly
goes into powersave mode. If I use the fglrx driver, it's even worse: I
can't
even boot into KDM.
The system is still functional, because I can still ssh into it. Any
additional
message needed? This is driving me crazy.
