Ok. Just did a search to find out what CPU CX states were. For a good explanation of the CX states: http://lists.freebsd.org/pipermail/freebsd-current/2009-May/006436.html > > Switching speeds relies on the dev.cpu.0.freq and dev.cpu.0.freq_levels > sysctls - are these available when you're running on APM?

And powerd in verbose foreground mode shows that it is lowering the frequency all the way down to 75 MHz depending on the load. Cool. Thanks again, Ian.

This fixed the problem where suspend would hang the second time it was executed in X. At any rate, I gave up on ACPI. I've got suspend-to-ram and suspend-to-disk (hibernation) working perfectly using APM. Does anyone know if there are any disadvantages related to power-saving features when using APM over ACPI?

Suspend/Resume on Thinkpad x40
Hi all, First off, I apologize if this is not the right forum for this question. I was torn between posting this in mobile, ACPI, X11 and here. If I might get a better response in one of those forums, please let me know and I'll post there instead. I'm having some trouble getting the kinks worked out of the suspend/resume functionality on my laptop, an IBM Thinkpad X40. It is mostly working now, but I am still experiencing some strange behavior. I can suspend and resume from a console just fine (except for the fact that the console comes up blank and only displays new characters); however, suspending and resuming in X is problematic. The first suspend and resume in X works perfectly, but the next time I hit suspend, the machine locks up while still displaying whatever I was doing in X. Note that if I switch to a virtual terminal before hitting suspend, this problem does not occur. Does anyone have any suggestions on what I might do to get this resolved? The details of my machine follows; please let me know if any additional information would be helpful. > uname -a FreeBSD sussman.snikeris.com 7.2-RELEASE-p2 FreeBSD 7.2-RELEASE-p2 #0: Wed Jun 24 00:57:44 UTC 2009 r...@i386-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC i386 > cat /boot/loader.conf # Disable boot menu beastie_disable="YES" autoboot_delay=-1 # Needed for firefox to display certain HTML5 elements sem_load="YES" # Needed so we can resume from suspend w/ a working display. hw.acpi.reset_video=1 # Needed so mouse will work on resume hint.psm.0.flags="0x3000" # Possibly needed for successful resume hint.apic.0.disabled=1 # Needed for sound snd_ich_load="YES" # Needed for wireless (iwi) if_iwi_load="YES" wlan_load="YES" firmware_load="YES" iwi_bss_load="YES" iwi_ibss_load="YES" iwi_monitor_load="YES" legal.intel_iwi.license_ack=1 # Needed for 3d graphics acceleration agp_load="YES" # Needed for cdrecord to work atapicam_load="YES" # See 'man acpi_ibm' acpi_ibm_load="YES" > cat /etc/rc.conf # -- sysinstall generated deltas -- # Sat Jul 4 11:10:49 2009 # Created: Sat Jul 4 11:10:49 2009 # Enable network daemons for user convenience. # Please make all changes to this file, not to /etc/defaults/rc.conf. # This file now contains just the overrides from /etc/defaults/rc.conf. # Set by sysinstall hostname="sussman.snikeris.com" #ifconfig_em0="DHCP" linux_enable="YES" moused_enable="YES" # Allow X to locate mouse and keyboard automatically using HAL hald_enable="YES" dbus_enable="YES" keyrate="fast" keybell="off" > cat /etc/sysctl.conf # $FreeBSD: src/etc/sysctl.conf,v 1.8.32.1 2009/04/15 03:14:26 kensmith Exp $ # # This file is read when going to multi-user and its contents piped thru # ``sysctl'' to adjust kernel values. ``man 5 sysctl.conf'' for details. # # Uncomment this to prevent users from seeing information about processes that # are being run under another UID. #security.bsd.see_other_uids=0 hw.acpi.standby_state=S0 hw.acpi.suspend_state=S3 hw.acpi.sleep_button_state=S3 vfs.usermount=1 hw.acpi.sleep_delay=3 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Clearing ttyv0 after boot
Hi all, As the subject suggests, I'd like to clear ttyv0 immediately after booting so that it looks exactly like the other ttys. I suspect I might have to add a local rc script, but I'm fairly new to FreeBSD and am not sure if this is the correct way to go. Does anyone have any pointers?
