I suspect -mobile might be the best list for this one, perhaps -acpi but that's usually more about development than usage. You might try searching the archives of either for mention of the X40. > I'm having some trouble getting the kinks worked out of the > suspend/resume functionality on my laptop, an IBM Thinkpad X40.

My T23 requires hw.syscons.sc_no_suspend_vtswitch=1 to suspend/resume cleanly (7.0), so does my old Compaq Armada (but that's APM, not ACPI) > > uname -a > FreeBSD sussman.snikeris.com 7.2-RELEASE-p2 FreeBSD 7.2-RELEASE-p2 #0: > Wed Jun 24 00:57:44 UTC 2009 > root@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 That might be one to try either way, with other combinations. > # 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" I've found that vesa_load="YES" helps on my T23 especially if suspending from a VT rather than in X, referring to your 'console comes up blank.' Something to try anyway, and I don't think it ever hurts. > > 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 If hw.syscons.sc_no_suspend_vtswitch=1 is no help, I'd try -mobile .. cheers, Ian
