  • How do you completely reset monitor configuration (e.g. what used to be dpkg-reconfigure xserver-xorg)?

    - by John
    Using unity 11.04. I have a secondary monitor (actually two, one at home, one at work). The home twin monitor set up works perfect (Viewsonic monitor). At work, I get very buggy behaviour, such as full screen applications 'ghosting' when maximized, and other strange effects. I would like to try and completely reset the monitor configurations (not unity or compiz), before doing anything else. In 10.10 this would be accomplished: dpkg-reconfigure xserver-xorg

  • Is Perl's flip-flop operator bugged? It has global state, how can I reset it?

    - by Evan Carroll
    I'm dismayed. Ok, so this was probably the most fun perl bug I've ever found. Even today I'm learning new stuff about perl. Essentially, the flip-flop operator .. which returns false until the left-hand-side returns true, and then true until the right-hand-side returns false keep global state (or that is what I assume.) My question is can I reset it, (perhaps this would be a good addition to perl4-esque hardly ever used reset())? Or, is there no way to use this operator safely? I also don't see this (the global context bit) documented anywhere in perldoc perlop is this a mistake? Code use feature ':5.10'; use strict; use warnings; sub search { my $arr = shift; grep { !( /start/ .. /never_exist/ ) } @$arr; } my @foo = qw/foo bar start baz end quz quz/; my @bar = qw/foo bar start baz end quz quz/; say 'first shot - foo'; say for search \@foo; say 'second shot - bar'; say for search \@bar; Spoiler $ perl test.pl first shot foo bar second shot

  • How to reset mysql's replication settings completely, without reinstalling it?

    - by user38060
    I set up mysql replication by adding references to binlogs, relay logs etc in my.cnf restarted mysql, it worked. I wanted to change it so I deleted all binlog related files including log-bin.index, removed binlog statements from my.cnf restarted server, works set master to '', purge master logs since now(), reset slave, stop slave, stop master. now, to set up replication again, I added binlog statements to the server. But then I hit this problem when restarting with: sudo mysqld (the only way to see mysql's startup errors) I get this error: /usr/sbin/mysqld: File '/etc/mysql/var/log-bin.index' not found (Errcode: 13) Because indeed, this file does not exist! (I deleted it, while trying to set up a new replication system) Hmm, if I change the config line to: log-bin-index = log-bin.index I get a different error: [ERROR] Can't generate a unique log-filename /etc/mysql/var/bin.(1-999) [ERROR] MSYQL_BIN_LOG::open failed to generate new file name. [ERROR] Aborting The first time I set up replication on this system, I didn't need to create this file. I did the same thing - added references to a previously non-existing file, and mysql created it. Same with relay logs, etc. I don't know why mysql insists on trying to read the old folder. Should I just reinstall the whole package again? That seems like overkill. my my.cnf: [client] port = 3306 socket = /var/run/mysqld/mysqld.sock [mysqld_safe] socket = /var/run/mysqld/mysqld.sock nice = 0 [mysqld] user = mysql socket = /var/run/mysqld/mysqld.sock port = 3306 basedir = /usr datadir = /var/lib/mysql tmpdir = /tmp skip-external-locking bind-address = IP key_buffer = 16M max_allowed_packet = 16M thread_stack = 192K thread_cache_size = 8 myisam-recover = BACKUP table_cache = 64 sort_buffer =64K net_buffer_length =2K query_cache_limit = 1M query_cache_size = 16M slow_query_log_file = /etc/mysql/var/mysql-slow.log long_query_time = 1 log-queries-not-using-indexes expire_logs_days = 10 max_binlog_size = 100M server-id = 3 log-bin = /etc/mysql/var/bin.log log-slave-updates log-bin-index = /etc/mysql/var/log-bin.index log-error = /etc/mysql/var/error.log relay-log = /etc/mysql/var/relay.log relay-log-info-file = /etc/mysql/var/relay-log.info relay-log-index = /etc/mysql/var/relay-log.index auto_increment_increment = 10 auto_increment_offset = 3 master-host = HOST master-user = USER master-password=PWD replicate-do-db = DBNAME collation_server=utf8_unicode_ci character_set_server=utf8 skip-character-set-client-handshake [mysqldump] quick quote-names max_allowed_packet = 16M [mysql] #no-auto-rehash [myisamchk] key_buffer_size = 16M sort_buffer_size = 8M [mysqlhotcopy] interactive-timeout !includedir /etc/mysql/conf.d/ Update: Changing all the /etc/mysql/var/xxx paths in binlog & relay log statements to local has somehow solved the problem. I thought it was apparmor causing it at first, but when I added /etc/mysql/* rw, to apparmor's config and restarted it, it still couldn't read the full path.

  • How to set Grub to automatically load Xen kernel

    - by Cerin
    How do you configure Grub to automatically use the Xen kernel under Ubuntu 11.10? No matter what I do, it loads the first menuentry. The only way I can get it to load Xen is to manually select the kernel, which I can't do if I have to reboot the server remotely, or there's a power failure and the machine automatically boots up when power's restored, etc. It's driving me nuts. In my /boot/grub/grub.cfg, the Xen kernel is at index 4 (i.e. it's the 5th menuentry). So I've tried: Setting GRUB_DEFAULT=4, and running sudo update-grub Setting GRUB_DEFAULT=saved and GRUB_SAVEDEFAULT=true, and running sudo update-grub Setting GRUB_DEFAULT="Ubuntu GNU/Linux, with Xen 4.1-amd64 and Linux 3.0.0-16-server", and running sudo update-grub None of these work. It continues to load the first menuentry, which is "Ubuntu, with Linux 3.0.0-16-server". Below is my current /boot/grub/grub.cfg. What am I doing wrong? # # DO NOT EDIT THIS FILE # # It is automatically generated by grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN

    Can you set the default button of a panel with a button that is not in that panel but in another content placeholder within a master page? I have tried this but I get the following error: The DefaultButton of 'pnlTmp' must be the ID of a control of type IButtonControl.

  • Metamorphs Messing Up CSS in Ember.js Views

    - by Austin Fatheree
    I'm using Ember.js / handlebars to loop through a collection and spit out some items that I'd like bootstrap to handle nice and responsive like. Here is the issue: The bootstrap-responsive css has some declrations in it like: .row-fluid > [class*="span"]:first-child { margin-left: 0; } and .row-fluid:before, .row-fluid:after { display: table; content: ""; } These rules seem to target the first children. When I loop through my collection in handlebars I end up with a bunch of metamorph code around my items: <div class="row-fluid"> {{#each restaurantList}} {{view GS.vHomePageRestList content=this class="span6"}} {{/each}} </div> Here is what is produced: <div class="row-fluid"> <script id="metamorph-9-start" type="text/x-placeholder"></script> <script id="metamorph-104-start" type="text/x-placeholder"></script> <div id="ember2527" class="ember-view span6"> My View </div> <script id="metamorph-104-end" type="text/x-placeholder"></script> <script id="metamorph-105-start" type="text/x-placeholder"></script> <div id="ember2574" class="ember-view span6"> My View 2 </div> <script id="metamorph-105-end" type="text/x-placeholder"></script> <script id="metamorph-9-end" type="text/x-placeholder"></script> </div> So my question is this: 1. How can I tell css to ignore script tags? or 2. How can I edit the css bindings so that they skip over script tags when selecting the first or first child? or 3. How can I structure this so that Ember uses fewer/no metamorph tags? Here is a fiddle: http://jsfiddle.net/skilesare/SgwsJ/

  • Cocos2d push scene with parameter, the parameter is reset after push. How to troubleshoot? Thoughts?

    - by user72693
    In the helloWorldLayer.m, I push a scene with some parameter like this [[CCDirector sharedDirector] replaceScene:[CCTransitionFade transitionWithDuration:0.2 scene:[RootLayer sceneWithInt:123]]]; where the RootLayer I have a modified method +(CCScene *) sceneWithInt:(int) i{ CCScene *scene = [CCScene node]; GameplayLayer *layer = [[GameplayLayer node] retain]; [layer setTestInt:i]; [scene addChild: layer z:0 tag:100]; return scene; } In the above, the "GameplayLayer" has an Int property "TestInt" which I would like to set it before this layer is push. However, the moment the GameplayLayer is loaded, that TestInt property is reset to 0. It is not passing correctly. I remember in my last project this can be done. How to troubleshoot this?

  • Is it possible to reset NSURLConnection after providing credentials?

    - by John
    I am calling a REST service that requires basic auth and I respond to the didReceiveAuthenticationChallenge delegate OK NSURLCredential *credential = [[NSURLCredential alloc] initWithUser:self.user password:self.password persistence:NSURLCredentialPersistenceForSession]; [[challenge sender] useCredential:credential forAuthenticationChallenge:challenge]; [credential release]; The Credentials are valid for the Session but I would like for my App to be able to switch between servers and therefore need to "reset" the Session so it asks again for a challenge. I can of course try the option of not storing the credentials for the Session and supply them for each call but this does not seem like a good idea. Any ideas would be appreciated!

  • How do I git reset --hard HEAD on Mercurial?

    - by obvio171
    I'm a Git user trying to use Mercurial. Here's what happened: I did a hg backout on a changeset I wanted to revert. That created a new head, so hg instructed me to merge (back to "default", I assume). After the merge, it told me I still had to commit. Then I noticed something I did wrong when resolving a conflict in the merge, and decided I wanted to have everything as before the hg backout, that is, I want this uncommited merge to go away. On Git this uncommited stuff would be in the index and I'd just do a git reset --hard HEAD to wipe it out but, from what I've read, the index doesn't exist on Mercurial. So how do I back out from this?

  • How can I avoid properties being reset at design-time in tightly bound user controls?

    - by David Anderson
    I have UserControl 'A' with a label, and this property: /// <summary> /// Gets or Sets the text of the control /// </summary> [ Browsable(true), EditorBrowsable(EditorBrowsableState.Always), Category("Appearance") ] public override string Text { get { return uxLabel.Text; } set { uxLabel.Text = value; } } I then have UserControl 'B' which has UserControl 'A' on it, and I set the Text Property to "My Example Label" in the designer. Then, I have my MainForm, which has UserControl 'B' on it. Each time I do a build or run, the Text property of UserControl 'A' is reset to its default value. I suppose this is because since I am doing a rebuild, it rebuilds both UserControl 'A' and 'B', thus causing the problem. How can I go about a better approach to design pattern to avoid this type of behavior when working with tightly bound controls and forms in a application?

  • C# MDX RenderToSurface, where to reset after device is lost?

    - by Moritz Schöfl
    Hi, I got a problem with the RenderToSurface class. When I resize the Form of my Device, the Draw method is still called, but doesnt throw an Exception, it looks like this: device.Clear(ClearFlags.Target, Color.Red, 0, 0); device.BeginScene(); // here is out commented code device.EndScene(); device.Present(); In another method, I wrote this: renderToSurface.BeginScene(surfaces[currentIndex]); // here is out commented code renderToSurface.EndScene(Filter.None); and this method seems to throw a nullpointer exception when I resize the window; So my question is: - where to reset / restore / handle the renderToSurface class? (i tried it with the DeviceReset event like following - void OnDeviceReset(object sender, EventArgs e) { renderToSurface = new RenderToSurface(Game.Device, Game.ClientSize.Width, Game.ClientSize.Height, Format.A8R8G8B8, true, DepthFormat.D16); } )

    - by Euclid
    i have an array of buttons added to a panel control and need to reset them to their original values, is this possible pragmatically? protected void Page_Load(object sender, EventArgs e) { RenderTable(); } private void RenderTable() { Button[] board = new Button[9]; for(int i =0; i <board.Length; i++) { board[i] = new Button(); board[i].Text = " "; board[i].Width= board[i].Height = 50; board[i].Click += PlayerClick; board[i].ID = "pos" + i; Panel1.Controls.Add(board[i]); } }

  • Why is the EntityManager in my GAE + Spring (+graniteds) project reset to null?

    - by prefabSOFT
    Hi all, I'm having a problem with autowiring my EntityManager. Actually at server startup I can see that the injection works ok, though when trying to use my EntityManager it appears to be null again. @Component public class DataDaoImpl { protected EntityManager entityManager; @Autowired public void setEntityManager(EntityManager entityManager) { System.out.println("Injecting "+entityManager); //works! this.entityManager = entityManager; } public void createData(String key, String value) { System.out.println("In createData entityManager is "+entityManager); //entityManager null!? ... Output: Injecting org.datanucleus.store.appengine.jpa.DatastoreEntityManager@a60d19 The server is running at http://localhost:8888/ In createData entityManager is null So somehow the autowired entityManager is reset to null when trying to use it. It's a graniteds powered project though I don't think this is graniteds related. Any ideas? Thanks a lot in advance, Jochen
