[ltp] T40 - Consensus on the blank screen coma (LCD sleep) issue?

[Mark G. Spencer]

Hi Satish,

I'm not very familiar with the Fedora version of Red Hat.  I'm using the =
Red
Hat 9 available from the Red Hat Network.

I just checked out the "Software" tab on RHN and I see a Red Hat 9 beta,
"Severn", but don't see any mention of Fedora.

Do you know if I can upgrade a Red Hat 9 (latest updates from RHN =
up2date)
kernel to the Fedora kernel?  My Linux expertise ends at =
configure/make/make
install, so I'm hoping I can do this without trashing my system.  ;)=20

I don't know what Rawhide is, but I'm jumping on Redhat's website now to
find out.

Thanks!

Mark

I've installed the latest redhat beta (fedora core test 2) on my T40 - =
and
screen blanking (Fn-F3) and suspend (Fn-F4) works fine. The default =
kernel
uses 'APM' instead of ACPI - and I'm pretty happy with it.

Currenlty I've upgraded to latest rawhide - and these 2 things still =
work.

I'll sugest installing the latest kernel from rawhide - and see if this
works for you.
