Well, I have the following as a work around to get aticonfig to set low power
mode:
----------------------------------------------------------
In /etc/default/fglrx, uncomment/set:
FGLRX_ACPI_SWITCH_POWERSTATES=true
-----
In /etc/default/fglrx, uncomment/set:
FGLRX_ACPI_SWITCH_POWERSTATES=true
----
Install the fglrx driver & make sure you can run 'aticonfig --lsp'
Then we need a modified version of /etc/acpi/fglrx-powermode.sh
-----
cat /etc/acpi/fglrx-powermode.sh | sed 's/su \$user -c \"\(.*\)\"/\1/' >
~/bin/fglrx-powermode.sh
chmod +x ~/bin/fglrx-powermode.sh
-----
Next, edit/create ~/.gnomerc to call the new script (eg):
sample ~/.gnomerc
------
#!/bin/bash
~/bin/fglrx-powermode.sh
------
chmod +x ~/bin/fglrx-powermode.sh
------
Now if you boot while on battery, ati-config --lsp should indicate the
vid card as in low power mode.
aticonfig --lsp
core/mem [flags]
-----------------
* 1: 111/111 MHz [low voltage]
2: 392/209 MHz [default state]
