by Hello,
I've got an IBM TP600 that works just great with Linux after following
the instructions on http://www.cs.utexas.edu/users/kharker/linux-laptop/.
Suspend and hibernate work great when invoked through the hot keys.
I'm now trying to go a bit further. kapm is a KDE apm program that's
supposed to allow suspend and hibernate through program control.
But since RedHat 5.2 did not come "APM ready", I have had to create my
own /dev/apm_bios file. I did:
mknod /dev/apm_bios c 10 134
chmod 666 /dev/apm_bios
Naturally, this creates the file just fine and makes it world-
writable. But now, kapm complains "Operation not permitted" when I
try to suspend, which, when looking at the kapm source, means that the
ioctl() failed.
System config:
RedHat 5.2
kernel 2.0.36 with the following APM settings:
Ignore user suspend=NO
Enable PM at boot=NO
Make CPU idle calls=YES
Enable console blanking=YES
Power off on shutdown=YES
Ignore multiple suspend=NO
What am I doing wrong? Thanks for any help.
