T20: display stays dark when booting with closed lid switch

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I'm not really sure whether this is in any way related to the IBM ACPI
drivers, or whether it could be solved in the IBM ACPI drivers - I hope
you can tell me, or possibly point me to whoever possibly could do
something about it ...

When I close the lid switch (of my T20 with T22 BIOS, as usual ;-) before
booting linux, the display stays dark when I open the switch afterwards.
That is, I boot into grub with the switch open, then press it down,
and let grub load linux. Now, I don't have a clue how long exactly I
have to wait before releasing the switch, but if I hold it down
until the basic hardware initialization (whatever that is, exactly ;-)
is over, it won't light up again.

Any hints?

Florian
