PURPOSE
=======
Xautolock monitors console activity under the X window system, and
fires up a program of your choice if nothing happens during a
user configurable period of time. You can use this to automatically
start up a screen locker in case you tend to forget to do so manually
before having a coffee break.
Xautolock will typically be used to lock the screen but it really
doesn't care what program you make it start. The only real assumption
made by xautolock is that a new countdown starts as soon as the
locker exits.
HOW TO USE IT
=============
Just read the man page, it's really simple.
If you're on VMS, you should also check out the VMS.notes file.
HOW IT WORKS
============
If xautolock has been compiled to support either the Xidle, or the
MIT ScreenSaver extensions (or both), it first tries to find out
whether the X server also supports one of them. If it does, xautolock
will periodically call it to determine the amount of time elapsed
since the last input event, and will then base its actions upon that.
In the absence of both extensions, xautolock starts by traversing the
window tree, selecting SubstructureNotify on all windows and adding
each window to a temporary list. About +- 30 seconds later, it scans
this list, asking for KeyPress events. However, it takes care
to interfere as little as possible with the event propagation
mechanism. This is the reason for the delay between the moment
xautolock learns about a new window (and consequently asks for
SubstructureNotify events) and the moment it asks for KeyPress
events. Whenever a new window is created by an application, a similar
process takes place. In contradiction to what many people believe,
this scheme does not cause a noticeable overhead.
In addition, xautolock periodically issues a QueryPointer request in
order to find out whether the pointer has moved and implement the
"corners" feature as decribed in the man page.
If nothing happens within a user-specified period of time, xautolock
will fire up a program which is supposed to lock the screen. While
this program is running, xautolock itself remains on the look-out for
user interaction.
COMPILING XAUTOLOCK
===================
Xautolock should compile straight out of the box. Here's the recepy:
1. Edit the Imakefile to your likings.
2. Type:
xmkmf
make
make install
make clean
3. Have fun.
If this procedure fails, the most likely reason is the absence of the
MIT ScreenSaver extension on your system. If this is the case, simply
edit the Imakefile accordingly and try again.
If compilation fails because MIT ScreenSaver is not available, do the
following:
+ Find out whether the X server supports it (use the xdpyinfo
command for this). Quite often it will, even if the support for
compiling programs with it is absent. If this applies to you,
nag your sysadmin and/or vendor about it. MIT ScreenSaver is a
pretty standard extension that IMHO should be provided with any
X based system.
+ If you cannot find MIT ScreenSaver, repeat the same procedure
with Xidle (except for the `nag your vendor' bit). If your
server supports Xidle, but you do not have the development
files and cannot find them on the web, just send me and e-mail
and I will forward you a copy.
+ If you are still out of luck, use the good old backup mechanism.
Xautolock wil be just as happy without server extensions.
Nowadays, all modern X servers come with MIT ScreenSaver. However,
some (or most/all?) of the HP ones apparently don't, so by default
this feature is disabled on HP-UX. Simply edit the Imakefile if you
disagree.
KNOWN BUGS
==========
Important notice: the first two bugs listed here are only present in
case xautolock has been compiled with support for neither the Xidle
nor the MIT ScreenSaver extensions, or in case the X server being
used does not support them. They make up a good reason to get one of
these extensions installed.
1. If, when creating a window, an application waits for more than
30 seconds before calling selecting KeyPress events on non-leaf
windows, xautolock may interfere with the event propagation
mechanism. This effect is theoretical and has never been
observed in real life.
2. Xautolock can not properly handle the secure keyboard mode of
xterm, since that will prevent any other process, including
xautolock, from noticing the keyboard events aimed at the
xterm. Consequently, xautolock sometimes will think that there
is no keyboard activity while in reality there is.
3. Under some configurations, xautolock fails to exit upon logout.
This problem can occur (but does not always do so) under the
following combined circumstances:
+ Xautolock is started in background from within a .xinitrc.
+ Your are trusting your windowmanager to kill all X processes
when quitting (which, by the way, is not a good idea). One
well known source of problems in this area consists of olwm
and its look-alikes.
+ The .xinitrc contains a "wait" statement to make it collect
all background processes upon logout.
The simplest workround for this problem is to start xautolock
from within a subshell. I.e. use this:
( xautolock & )
On Solaris an alternative solution (which basically works in
exactly the same way) is to use this:
toolwait xautolock
4. The -disable, -enable, -toggle, -exit, -locknow, -unlocknow,
and -restart options depend on access to the X server to do
their work. This implies that they will be suspended in case
some other application has grabbed the server all for itself.
5. Xautolock does not check whether the screen locker specified
actually is available.
6. The xautolock resources have a dummy resource classes.
If you can find others, please notify eyckmans@imec.be.
Note that, while I still scan most X related newsgroups, I do not
actually read them on a regular basis anymore, as X no longer is
a part of my job. I do still actively support xautolock on a daily
basis, though. Hence you are much more likely to get quick help if
you contact me directly.
WARNING
=======
It looks like there is a bug in the event management code of some X
servers (amongst which both X11R4 and X11R5 on older versions of
SunOS). If you are using version 1.7 of xautolock (previously known
as patchlevel 7), it is best to reset the server before switching to
version 1.8 or later. If you fail to do so, an old version 1.7 bug
may still show up. (Some keyboard events were being hijacked by
version 1.7 of xautolock, particularly when using tvtwm).
CONTRIB DIRECTORY
=================
The contrib directory may contain various patches that have been
contributed over time. If a patch is in there, I have for some reason
or another decided not to include it in xautolock proper, but still
consider it to be sufficiently usefull to other people in order to
add it to the distribution.
Note that the contents of the contrib directory are *not* part of
xautolock. Each of the contributions lives under its own copyright.
In version 2.0 of xautolock, the contrib directory is empty, since
due to a lack of time I did not feel like porting the stuff that used
to be in there to the new version. Maybe it'll be back in 2.1 or so.

A much more important factor in the social movement than those already mentioned was the ever-increasing influence of women. This probably stood at the lowest point to which it has ever fallen, during the classic age of Greek life and thought. In the history of Thucydides, so far as it forms a connected series of events, four times only during a period of nearly seventy years does a woman cross the scene. In each instance her apparition only lasts for a moment. In three of the four instances she is a queen or a princess, and belongs either to the half-barbarous kingdoms of northern Hellas or to wholly barbarous Thrace. In the one remaining instance208— that of the woman who helps some of the trapped Thebans to make their escape from Plataea—while her deed of mercy will live for ever, her name is for ever lost.319 But no sooner did philosophy abandon physics for ethics and religion than the importance of those subjects to women was perceived, first by Socrates, and after him by Xenophon and Plato. Women are said to have attended Plato’s lectures disguised as men. Women formed part of the circle which gathered round Epicurus in his suburban retreat. Others aspired not only to learn but to teach. Arêtê, the daughter of Aristippus, handed on the Cyrenaic doctrine to her son, the younger Aristippus. Hipparchia, the wife of Crates the Cynic, earned a place among the representatives of his school. But all these were exceptions; some of them belonged to the class of Hetaerae; and philosophy, although it might address itself to them, remained unaffected by their influence. The case was widely different in Rome, where women were far more highly honoured than in Greece;320 and even if the prominent part assigned to them in the legendary history of the city be a proof, among others, of its untrustworthiness, still that such stories should be thought worth inventing and preserving is an indirect proof of the extent to which feminine influence prevailed. With the loss of political liberty, their importance, as always happens at such a conjuncture, was considerably increased. Under a personal government there is far more scope for intrigue than where law is king; and as intriguers women are at least the209 equals of men. Moreover, they profited fully by the levelling tendencies of the age. One great service of the imperial jurisconsults was to remove some of the disabilities under which women formerly suffered. According to the old law, they were placed under male guardianship through their whole life, but this restraint was first reduced to a legal fiction by compelling the guardian to do what they wished, and at last it was entirely abolished. Their powers both of inheritance and bequest were extended; they frequently possessed immense wealth; and their wealth was sometimes expended for purposes of public munificence. Their social freedom seems to have been unlimited, and they formed combinations among themselves which probably served to increase their general influence.321 The old religions of Greece and Italy were essentially oracular. While inculcating the existence of supernatural beings, and prescribing the modes according to which such beings were to be worshipped, they paid most attention to the interpretation of the signs by which either future events in general, or the consequences of particular actions, were supposed to be divinely revealed. Of these intimations, some were given to the whole world, so that he who ran might read, others were reserved for certain favoured localities, and only communicated through the appointed ministers of the god. The Delphic oracle in particular enjoyed an enormous reputation both among Greeks and barbarians for guidance afforded under the latter conditions; and during a considerable period it may even be said to have directed the course of Hellenic civilisation. It was also under this form that supernatural religion suffered most injury from the great intellectual movement which followed the Persian wars. Men who had learned to study the constant sequences of Nature for themselves, and to shape their conduct according to fixed principles of prudence or of justice, either thought it irreverent to trouble the god about questions on which they were competent to form an opinion for themselves, or did not choose to place a well-considered scheme at the mercy of his possibly interested responses. That such a revolution occurred about the middle of the fifth century B.C., seems proved by the great change of tone in reference to this subject which one perceives on passing from Aeschylus to Sophocles. That anyone should question the veracity of an oracle is a supposition which never crosses the mind of the elder dramatist. A knowledge of augury counts among the greatest benefits222 conferred by Prometheus on mankind, and the Titan brings Zeus himself to terms by his acquaintance with the secrets of destiny. Sophocles, on the other hand, evidently has to deal with a sceptical generation, despising prophecies and needing to be warned of the fearful consequences brought about by neglecting their injunctions. The stranger had a pleasant, round face, with eyes that twinkled in spite of the creases around them that showed worry. No wonder he was worried, Sandy thought: having deserted the craft they had foiled in its attempt to get the gems, the man had returned from some short foray to discover his craft replaced by another. “Thanks,” Dick retorted, without smiling. When they reached him, in the dying glow of the flashlight Dick trained on a body lying in a heap, they identified the man who had been warned by his gypsy fortune teller to “look out for a hidden enemy.” He was lying at full length in the mould and leaves. "But that is sport," she answered carelessly. On the retirement of Townshend, Walpole reigned supreme and without a rival in the Cabinet. Henry Pelham was made Secretary at War; Compton Earl of Wilmington Privy Seal. He left foreign affairs chiefly to Stanhope, now Lord Harrington, and to the Duke of Newcastle, impressing on them by all means to avoid quarrels with foreign Powers, and maintain the blessings of peace. With all the faults of Walpole, this was the praise of his political system, which system, on the meeting of Parliament in the spring of 1731, was violently attacked by Wyndham and Pulteney, on the plea that we were making ruinous treaties, and sacrificing British interests, in order to benefit Hanover, the eternal millstone round the neck of England. Pulteney and Bolingbroke carried the same attack into the pages of The Craftsman, but they failed to move Walpole, or to shake his power. The English Government, instead of treating Wilkes with a dignified indifference, was weak enough to show how deeply it was touched by him, dismissed him from his commission of Colonel of the Buckinghamshire Militia, and treated Lord Temple as an abettor of his, by depriving him of the Lord-Lieutenancy of the same county, and striking his name from the list of Privy Councillors, giving the Lord-Lieutenancy to Dashwood, now Lord Le Despencer. "I tell you what I'll do," said the Deacon, after a little consideration. "I feel as if both Si and you kin stand a little more'n you had yesterday. I'll cook two to-day. We'll send a big cupful over to Capt. McGillicuddy. That'll leave us two for to-morrer. After that we'll have to trust to Providence." "Indeed you won't," said the Surgeon decisively. "You'll go straight home, and stay there until you are well. You won't be fit for duty for at least a month yet, if then. If you went out into camp now you would have a relapse, and be dead inside of a week. The country between here and Chattanooga is dotted with the graves of men who have been sent back to the front too soon." "Adone do wud that—though you sound more as if you wur in a black temper wud me than as if you pitied me." "Wot about this gal he's married?" "Don't come any further." "Davy, it 'ud be cruel of us to go and leave him." "Insolent priest!" interrupted De Boteler, "do you dare to justify what you have done? Now, by my faith, if you had with proper humility acknowledged your fault and sued for pardon—pardon you should have had. But now, you leave this castle instantly. I will teach you that De Boteler will yet be master of his own house, and his own vassals. And here I swear (and the baron of Sudley uttered an imprecation) that, for your meddling knavery, no priest or monk shall ever again abide here. If the varlets want to shrieve, they can go to the Abbey; and if they want to hear mass, a priest can come from Winchcombe. But never shall another of your meddling fraternity abide at Sudley while Roland de Boteler is its lord." "My lord," said Edith, in her defence, "this woman has sworn falsely. The medicine I gave was a sovereign remedy, if given as I ordered. Ten drops would have saved the child's life; but the contents of the phial destroyed it. The words I uttered were prayers for the life of the child. My children, and all who know me, can bear witness that I have a custom of asking His blessing upon all I take in hand. I raised my eyes towards heaven, and muttered words; but, my lord, they were words of prayer—and I looked up as I prayed, to the footstool of the Lord. But it is in vain to contend: the malice of the wicked will triumph, and Edith Holgrave, who even in thought never harmed one of God's creatures, must be sacrificed to cover the guilt, or hide the thoughtlessness of another." "Aye, Sir Treasurer, thou hast reason to sink thy head! Thy odious poll-tax has mingled vengeance—nay, blood—with the cry of the bond." HoME古一级毛片免费观看
