 |
|
Hi!
I just bought a new laptop with an ATI HD4570 card. I've emerged the ~amd64 x11-drivers/ati-drivers-9.8. It seems to work OK.
I'm trying to follow the Gentoo's Power Management Guide. However, I see ati-drivers-9.8 has installed some scripts in /etc/acpi: | Code: | $ ls -l
total 8
-rwxr-xr-x 1 root root 1684 Aug 29 01:01 ati-powermode.sh
-rwxr-xr-x 1 root root 1214 Aug 28 23:49 default.sh
drwxr-xr-x 2 root root 136 Aug 29 01:01 events
$ ls -l events
total 12
-rwxr-xr-x 1 root root 124 Aug 29 01:01 a-ac-aticonfig
-rwxr-xr-x 1 root root 132 Aug 29 01:01 a-lid-aticonfig
-rw-r--r-- 1 root root 663 Aug 28 23:49 default |
Do they interfere with the Power Management Guide? Does anybody have some experience on the matter?
Thanks in advance.
The conetents of the main scripts are: | Code: | $ cat ati-powermode.sh
#!/bin/bash
#

#

fi
if [ x"$user" != x"" ]; then
userhome=`getent passwd $user | cut -d: -f6`
export XAUTHORITY=$userhome/.Xauthority
else
export XAUTHORITY=""

}
