Re: [gentoo-user] laptop screen goes dark in boot

[Zhang Jun]

I get the dmesg log and kernel config, forgot to get the rc.log ( using
windows now ).
please help to have a look on these files,
also tryed boot with different kernel parameters for acpi, only acpi=off
works, but I don't think it is a good idea.
I'm using grub4dos with "kernel (hd0,7)/kernel-3.0.17-r1 root=/dev/sda9 ro
quiet vga=792 gentoo=nodevfs acpi_enforce_resources=lax
resume=swap:/dev/sda7", remove the "acpi_enforce_resources=lax" also not
works.

thanks!
