NAMEhibernate.conf - configuration file for the hibernate script
DESCRIPTIONThe hibernate script hibernate(8) reads its configuration from the /etc/hibernate/hiber‐ nate.conf file when it runs (unless an alternative configuration file is specified on the command line). If configuration directives are specified multiple times, typically the last one will take effect.
USAGEHibernateVT N If specified, output from the suspend script is redirected to the given VT instead of stdout. Verbosity N Determines how verbose the output from the suspend script should be: 0: silent except for errors 1: print steps 2: print steps in detail 3: print steps in lots of detail 4: print out every command executed (uses -x) LogFile <filename> If specified, output from the suspend script will also be redirected to this file - useful for debugging purposes. LogTimestamp <boolean> If logging to file, will place timestamps on each log entry. This is only recom‐ mended if you are trying to optimise suspend/resume time, otherwise it will just slow the process down. LogVerbosity N Same as Verbosity, but controls what is written to the logfile. AlwaysForce <boolean> If set to yes, the script will always run as if --force had been passed. AlwaysKill <boolean> If set to yes, the script will always run as if --kill had been passed. Distribution <debian|fedora|mandrake|redhat|gentoo|suse|slackware> If specified, tweaks some scriptlets to be more integrated with the given dis‐ tribution. Include <filename> Immediately include configuration directives from the given file. XDisplay <display location> Specifies where scriptlets that use the X server should find one. (Default: :0) UseACPISleep <state> Enables the use of /proc/acpi/sleep for suspending the machine. Be aware that this method is deprecated in favour of using /sys/power/state (with the sysfs_power_state scriptlet). This requires a kernel with ACPI support built in. <state> should generally be 3 (for suspend-to-RAM), or 4 (for suspend-to-disk). Note: You should not use this if you want to use TuxOnIce. BackLight <boolean> This will enable fancy backlight fading using the xbacklight program. Bootsplash <boolean> Showing script progress on an bootsplash enabled kernel. This will automatically enable SwitchToTextMode too. BootsplashConfig <configfile> Bootsplash config file (default is /etc/bootsplash/default/config/boot‐ splash-1024x768.cfg) SaveClock restore-only|<boolean> Set this to yes to save the system clock before suspending and restore the sys‐ tem clock after resuming. If set to restore-only, the clock will not be saved, only restored - this means suspending is faster, but if your hardware clock drifts significantly, your system clock will drift as well. IncompatibleDevices <device name> [...] If there are any processes accessing these devices, then suspending is aborted. If the --kill option is passed, the offending processes are terminated and the suspend continues. For example programs accessing the sound card (/dev/dsp*) or tuner cards (/dev/video*) would deny the respective modules from being unloaded. DisableWriteCacheOn <drive> [...] On some hardware the power is cut off before the disk has flushed its own hard‐ ware cache. List the devices that contain swap partitions (eg, /dev/hda) to dis‐ able the write cache before suspending. FBSplash <boolean> Showing script progress using fbsplash. No kernel patches are required, but you will need the fbsplash splashutils package installed (distinct from the boot‐ splash splashutils package). This will automatically enable SwitchToTextMode too. FBSplashTheme <themename> FBSplash theme name (default is taken from /proc/cmdline) Unmount <mount point or device> [...] If you have network shares or external devices that should be unmounted before suspending, list them here. Mount <mount point or device> [...] If you have network shares or external devices that should be mounted after resuming, list them here. UnmountFSTypes <filesystem type> [...] Unmounts any filesystems of the given types. This is most useful for network filesystems such as smbfs and nfs. UnmountGraceTime <seconds> Time between sending SIGTERM to processes and SIGKILL to allow them to cleanup gracefully.. The default is 1 second. LogoutGaim <boolean> Changes all locally running Gaim's status to offline before suspending, and (optionally) change it back to the original status after resuming. GaimRestoreStatus <boolean> Changes back Gaim's status to the original status after resuming. GaimLogoutMessage <string> Status message to set when logging out Gaim. GaimLoginMessage <string> Status message to set when logging in Gaim. GaleonOffline <boolean> Changes all locally running Galeon's status to offline before suspending, and (optionally) change it back to the original state after resuming. GaleonRestoreStatus <boolean> Change status of Galeon back to the original state after resuming. RestoreGFXBrightness <boolean> This will save and restore LCD brightness(GFX cards) using ACPI. ChangeGrubMenu <boolean> Change grub's config file to show system is suspended before suspending and restore after resume. GrubMenuFile <filename> Filename of grub's config file. Default is /boot/grub/grub.cfg. AlternateGrubMenuFile <filename> Filename of the grub config file to put in place when the machine is suspended. If this is not specified, the script will add a small header to the existing grub menu. BackupGrubMenuFile <filename> Where to keep a backup of your real grub menu file. Defaults to /var/back‐ ups/grub.cfg.hibernate. IbmAcpi <boolean> Use the ibm_acpi kernel module to signal suspend progress. RadeonTool <boolean> Use radeontool to turn off LCD backlight. Runi915resolution <boolean> Set to run 915resolution before switching back to X. FullSpeedCPU <boolean> Sets the CPU to full speed whilst suspending. AcpiVideoS3Bios <boolean> Sets s3_bios mode, replaces acpi_sleep=s3_bios kernel parameter. AcpiVideoS3Mode <boolean> Sets s3_mode mode, replaces acpi_sleep=s3_mode kernel parameter. EnsureLILOResumes <boolean> Makes sure that LILO boots the correct kernel image when rebooting to resume. This is useful when you boot into a non-default kernel or want to avoid LILO's menu delay when resuming. LockKDE <boolean> Lock all local KDE sessions before suspending. LockFreedesktop <boolean> Lock all local sessions compatible with freedesktop.org screensaver interface before suspending. LockXScreenSaver <boolean> Lock all local X11 sessions with xscreensaver running before suspending. LockGnomeScreenSaver <boolean> Lock all local X11 sessions with gnome-screensaver running before suspending. LockXLock <boolean> Lock active X11 session using xlock. LockXAutoLock <boolean> Lock all local X11 sessions running xautolock. LockConsoleAs <username> Locks the entire system after resuming, requiring you to enter either <user‐ name>'s or root's password to unlock it. (Requires vlock). LockXtrLock <boolean> Lock active X11 session using xtrlock. LockEnlightenment17 <boolean> Lock enlightenment17 session before suspending. OnSuspend NN <program to execute> [parameters for program] Executes a given program before suspending. NN is a two-digit number between 00 and 99, inclusive - a higher number means the program will be executed later in the suspend process. See the ORDERING section in the SCRIPTLET-API for details. OnResume NN <program to execute> [parameters for program] Executes a given program after resuming. NN is a number between 00 and 99, inclusive - a higher number means the program will be executed earlier in the resume process. See the ORDERING section in the SCRIPTLET-API for details. UnloadModules <module name> [...] Names of modules to unload prior to suspending. LoadModules auto|<module name> [...] Names of modules to load after resuming. If auto is specified, the modules that were unloaded previously are loaded. UnloadBlacklistedModules <boolean> Try to remove any modules that are known to be incompatible with hibernation prior to suspending. UnloadAllModules <boolean> Try to remove all modules loaded prior to suspending. LoadModulesFromFile <filename> Load default modules after resuming from a given filename. Each module name must appear on its own line, and lines starting with # are ignored. (eg, Debian's /etc/modules, Gentoo's /etc/modules.autoload) GentooModulesAutoload <boolean> Try to load default modules after resuming (from /etc/modules.autoload) DownInterfaces auto|<ifname> [...] The names of network interfaces to bring down before suspending. If the parame‐ ter "auto" is given, all interfaces which are not lo are brought down. UpInterfaces auto|<ifname> [...] The names of network interfaces to bring up after suspending. If the parameter "auto" is given, the interfaces stopped before suspending will be started in reverse order. EnableNMReconnect <boolean> Disconnect and reconnect NM before and after suspending. MuteAudio <boolean> This will mute your speakers on suspend to avoid compromising situations on resume. PauseAudio <boolean> This will pause your audio player before suspending. Audio is not unpaused on resume. EjectCards <boolean> Eject all PCMCIA cards before suspending, and insert them again after resuming LogoutPidgin <boolean> Changes all locally running Pidgin's status to offline before suspending, and (optionally) change it back to the original status after resuming. PidginRestoreStatus <boolean> Changes back Pidgin's status to the original status after resuming. PidginLogoutMessage <string> Status message to set when logging out Pidgin. PidginLoginMessage <string> Status message to set when logging in Pidgin. IncompatiblePrograms <process name> [...] If there are processes running with any of the names listed (as seen in ps ax), then suspending is aborted. If the --kill option is passed, the offending pro‐ cesses are terminated, and the suspend continues. RemountXFSBoot <boolean> Remount the /boot partition read-only when suspending to prevent against an XFS bug. StopServices <service name> [...] The services listed are stopped prior to suspending. The service name must cor‐ respond to the name of an init.d script that is active in the current runlevel. StartServices <service name> [...] The services listed are started after resuming. The service name must correspond to the name of an init.d script that is active in the current runlevel. RestartServices <service name> [...] The services listed are stopped before suspending and started after resuming. The service name must correspond to the name of an init.d script that is active in the current runlevel. AgentsClearGPG <boolean> Clear private data (passphrase) from gpg-agent AgentsClearSSH <boolean> Clear private data (passphrase) from ssh-agent SylpheedClawsOffline <boolean> Changes status of all locally running Sylpheed Claws to offline before suspend‐ ing, and (optionally) change it to online after resuming. SylpheedClawsOnline <boolean> Changes status of all locally running Sylpheed Claws to online after resuming. UseSysfsPowerState <state> Enables the use of /sys/power/state for suspending the machine (to RAM or disk). This requires a kernel supporting this interface. <state> must be one of the options listed by `cat /sys/power/state`, (eg mem, disk, or standby). PowerdownMethod <shutdown|platform|firmware> (requires UseSysfsPowerState) If using /sys/power/state to suspend your machine to disk, chooses the method by which to do so. Choosing "shutdown" will save state in linux, then tell the bios to powerdown (most reliable). Choosing "platform" will save state in linux, then tell the bios to powerdown and blink it's "suspended LED". Choosing "firmware" will tell the bios to save state itself (needs BIOS-specific suspend partition, and has very little to do with swsusp). UseTuxOnIce <boolean> Enable/disable the use of TuxOnIce to hibernate. Reboot <boolean> (requires UseTuxOnIce on) Controls whether or not TuxOnIce should reboot after hibernating. Setting this to yes will force a reboot. Setting this to no will force shutting down. Omit‐ ting this option will leave rebooting behaviour unchanged. EnableEscape <boolean> (requires UseTuxOnIce on) If specified, allows (or disallows) the use of the escape key to abort a hiber‐ nation cycle. If this line is not specified, the Escape key's behaviour is unchanged. DefaultConsoleLevel <N> (requires UseTuxOnIce on) If specified, sets the default console level. 0 gives a progress bar. 1 gives a progress bar with numbers. 2 or higher give increasing amounts of debugging. If this line is not specified, the default console level is unchanged. ImageSizeLimit nocache|<NN> (requires UseTuxOnIce on) If specified, sets an upper limit on the size of the hibernation image written (in megabytes). If set to "nocache", caches and buffers will not be saved - resulting in a faster hibernation and resume at the possible expense of system responsiveness immediately after resuming. If set to 0, no limit is imposed. If this line is not specified, the existing image size limit is unchanged. AsyncIOLimit <N> (requires UseTuxOnIce on) Deprecated since 126.96.36.199 (hence won't do anything if set). Limit the number of I/O operations that TuxOnIce will have queued at once. Lowering this value has resolved hangs when reading or writing caches for some people. Try values like 64, 32 and 8. SuspendDevice <device> (requires UseTuxOnIce on) If specified, sets the hibernation device by writing to the resume entry in . This does not automatically set the resuming device - you will need to make sure your bootloader or initrd script does this. FilewriterLocation <filename> <size in MB> (requires UseTuxOnIce on) This option sets up the given filename to act as a destination file for writing the hibernation image to, and verifies that it can act as a valid destination. If the file does not exist, the file is created. This option is only relevant if you are using the filewriter plugin for TuxOnIce. VerifyFilewriterResume2 <boolean> (requires UseTuxOnIce on) When this option is on, you will be prompted if your current kernel command-line does not match the correct resume for the filewriter. This option is on by default. LoadSuspendModules <module name> [...] (requires UseTuxOnIce on) Loads the given modules before even detecting TuxOnIce. This may be required when TuxOnIce is compiled as modules that need to be loaded prior to hibernat‐ ing. UnloadSuspendModulesAfterResume <boolean> (requires UseTuxOnIce on) If yes, will unload the TuxOnIce modules mentioned above after resuming. PowerdownMethod <0|3|4|5> (requires UseTuxOnIce on) Allows you to choose what TuxOnIce should do after writing its image to disk. 3/4/5 will only work if you have ACPI enabled in your kernel. 3/4/5 correspond to the ACPI states S3 (suspend-to-RAM), S4 (hibernate-to-disk), and S5 (power off). Choosing 3 will request your machine to enter the S3 Suspend-to-RAM state if it is supported - this allows you drastically cut the resume time waiting for your BIOS but still consumes power whilst hibernated (though the image is not lost should power run out). Choosing 4 will cause your machine to enter an S4 sleep state which may also reduce the resume time without using any power whilst hibernated. Choosing 5 will cause your machine to switch off after hibernating (traditional method) but might still cause your machine to resume when you open the lid. 0 bypasses ACPI and shuts off the machine completely. Compressor none|<compressor name> (requires UseTuxOnIce on) Sets the compression algorithm to use for compressing the memory image. If set to "none", disables compression. Otherwise, the compressor name must be listed in /proc/crypto. This will also try to load the module if not available. (Only for TuxOnIce.1.9.5 or newer). Encryptor none|<encryptor name> (requires UseTuxOnIce on) Sets the encryption algorithm to use for encrypting the memory image. If set to "none", disables encryption. Otherwise, the cipher name must be listed in /proc/crypto. This will also try to load the module if not available. You will probably require more options than just this to fully use encryption. These will be introduced in the next version of hibernate, but for now you can set them using the "ProcSetting" option if you know what you are doing. (Only for TuxOn‐ Ice.1.9.5 or newer). ProcSetting <entry name> <value> (requires UseTuxOnIce on) Sets the value of /<entry_name> to <value> upon hibernating. You can use this setting to set parameters that can't be configured anywhere else in this script. This is executed after all other settings have been set. USuspendMethod <disk|ram|both> Enables use of the uswsusp suspend method of newer kernels (>= 2.6.17rc1) USuspendRamForce <boolean> Passes the -f flag to s2ram to force suspending even if the machine is not recognised USuspendRamUnsureOk <boolean> Instructs s2ram to continue when it's unsure about the system type, thus not requiring -f to be passed USuspendRamVbeSave <boolean> Passes the -s flag to s2ram to save VBE state before suspending and restore after resume USuspendRamVbePost <boolean> Passes the -p flag to s2ram to VBE POST the graphics card after resume USuspendRamVbeMode <boolean> Passes the -m flag to s2ram to get VBE mode before suspend and set it after resume USuspendRamRadeontool <boolean> Passes the -r flag to s2ram to let radeontool turn of the backlight before sus‐ pending. USuspendRamAcpiSleep <number> Passes the -a flag to s2ram to set the acpi_sleep parameter before suspend: 1=s3_bios, 2=s3_mode, 3=both USuspendRamPciSave <boolean> Passes the -v flag to s2ram to have the PCI config space of the VGA card before suspend, and restore it on resume EnableVbetool <boolean> Save and restore video state using vbetool before and after suspending. RestoreVbeStateFrom <filename> If set, will restore the VBE state with the data stored in <filename>. Use this if your card requires you to restore it with a state captured at boot (from sin‐ gle user mode, run "vbetool vbestate save > /var/lib/vbetool/vbestate"). If this option is not set, the state is saved just before suspending. VbetoolPost <boolean> If yes, will call the video BIOS's POST routine to reinitialise the video card. Some cards need this to turn on the backlight back and be useful after resuming. Other video cards will hang if you attempt to POST them. Try it with yours and see. RestoreVCSAData <boolean> If yes, will call save and restore some of the video card's state from /dev/vcsa. This helps certain drivers such as ATI's fglrx driver to resume prop‐ erly. EnableVideoDump <boolean> Dump and load video card memory before and after suspending. SuspendVirtualbox <boolean> This will run "VBoxManage controlvm <VM> savestate" for each running VM and restore state on resume. EnableWICDReconnect <boolean> Disconnect and reconnect WICD before and after suspending. SwitchToTextMode <boolean> If your X driver is unable to resume properly, you can try switching to a text console first by setting this to yes. SwitchToTextModeOnResume <boolean> Use this to, on resume, switch to a text console and back. Some X drivers need this to properly resume. UseDummyXServer <boolean> Some X drivers can be reinitialised by launching a dummy X server after resuming to restore the state of the graphics card. Set this to yes to do so. DummyXServerConfig <filename> When using a dummy X server, use /etc/X11/<filename> as its configuration. XStatus <gnome|kde|x> Enables progress display and error reporting for the given environment. XmessageDisable <boolean> Disable display of xmessage dialogs if XStatus is set to "x". XSuspendText <message> Text to display on screen whilst preparing to suspend. (default: "Preparing to suspend...") XResumeText <message> Text to display on screen whilst coming back from suspend. (default: "Resuming from suspend...") XosdSettings <options> Options to pass to osd_cat, see 'man osd_cat' (default: "--font '-misc-fixed- medium-r-semicondensed--*-120-*-*-c-*-*-*' --colour=Green --shadow 1 --pos bot‐ tom --align center --offset 50")
