I've installed CentOS 5.4 on my new Lenovo Ideapad S12 (Atom-based 12" notebook) and need to add a quirk to pm-suspend in order for the laptop to actually go to sleep. There's a couple of quirks that work just fine so I really don't have a preference.
I found several instructions but most of them have failed me because CentOS's pm-utils is too ancient. Newer versions come with a parameter that adds the quirk to hald automatically, the CentOS version of pm-utils does not have this function yet. I've tried adding a /etc/pm/ config.d/99local config file with DISPLAY_QUIRK_VBE_POST="true" and a /etc/ hal/fdi/information/99local-pm-utils-quirks.fdi manually to no avail:
<?xml version="1.0" encoding="ISO-8859-1"?> <!-- -*- SGML -*- --> <!-- Created by pm-utils --> <deviceinfo version="0.2"> <device> <merge key="power_management.quirk.dpms_on" type="bool">false</merge> <merge key="power_management.quirk.dpms_suspend" type="bool">false</merge> <merge key="power_management.quirk.vbe_post" type="bool">true</merge> <merge key="power_management.quirk.vbemode_restore" type="bool">false</ merge> <merge key="power_management.quirk.vbestate_restore" type="bool">false</ merge> <merge key="power_management.quirk.vga_mode_3" type="bool">false</merge> </device> </deviceinfo>
But nothing seems to work. Running pm-suspend does not do anything, running pm-suspend --quirk-vbe-post puts the Laptop to sleep.
Any ideas?
