  • suspend resume not working on HP dv7

    - by Emiel
    this one is driving me nuts. My HP dv7 laptop isn't resuming from suspend and hybernate. On suspend - resume it leaves me with a black screen. On hibernate it succesfully loads the images and then it hangs.... I searched through internet and tried serveral things, but nothing seems to work for this HP dv7 on Ubuntu 12.04. With 11.10 it didn't work either. Intel® Core™ i5 CPU M 450 @ 2.40GHz × 4 VESA: Intel®Ironlake Mobile Graphics 64-bit Hope someone knows where to start the search.. I'm really desperate.

  • Ubuntu does not work with Nvidia drivers, gives random squares after logging in

    - by jimbo
    I tried installing both with wubi and by booting from a usb drive. After I tried both it was the same. Ubuntu tried to login, but after a while, a weird pattern with squarely shapes appeared. At one point, after using recovery mode and then the low graphics one (i don't remember how it was called exactly) i managed to get in. It still didn't display at correct resolution, and the mouse was invisible at times. However, after rebooting once, because i tried downloading the nvidia drivers, i didn't manage to get in again, so i have the same problem... I have no idea what to try to become unstuck. The main problem is that after the login, ubuntu crashes, with a screen full of randomly coloured squares. Should I just give up?

  • Keybindings for individual letter keys (not modifier-combinations) on a GtkTextView widget (Gtk3 and PyGI)

    - by monotasker
    I've been able to set several keybord shortcuts for a GtkTextView and a GtkTextEntry using the new css provider system. I'm finding, though, that I only seem to be able to establish keybindings for combinations including a modifier key. The widget doesn't respond to any bindings I set up that use: the delete key the escape key individual letter or punctuation keys alone Here's the code where I set up the css provider for the keybindings: #set up style context keys = Gtk.CssProvider() keys.load_from_path(os.path.join(data_path, 'keybindings.css')) #set up style contexts and css providers widgets = {'window': self.window, 'vbox': self.vbox, 'toolbar': self.toolbar, 'search_entry': self.search_entry, 'paned': self.paned, 'notelist_treeview': self.notelist_treeview, 'notelist_window': self.notelist_window, 'notetext_window': self.notetext_window, 'editor': self.editor, 'statusbar': self.statusbar } for l, w in widgets.iteritems(): w.get_style_context().add_provider(keys, Gtk.STYLE_PROVIDER_PRIORITY_USER) Then in keybindings.css this is an example of what works: @binding-set gtk-vi-text-view { bind "<ctrl>b" { "move-cursor" (display-lines, -5, 0) }; /* 5 lines up */ bind "<ctrl>k" { "move-cursor" (display-lines, -1, 0) }; /* down */ bind "<ctrl>j" { "move-cursor" (display-lines, 1, 0) }; /* up */ } Part of what I'm trying to do is just add proper delete-key function to the text widgets (right now the delete key does nothing at all). So if I add a binding like one of these, nothing happens: bind "Delete" { "delete-selection" () }; bind "Delete" { "delete-from-cursor" (chars, 1) }; The other part of what I want to do is more elaborate. I want to set up something like Vim's command and visual modes. So at the moment I'm just playing around with (a) setting the widget to editable=false by hitting the esc key; and (b) using homerow letters to move the cursor (as a proof-of-concept exercise). So far there's no response from the escape key or from the letter keys, even though the bindings work when I apply them to modifier-key combinations. For example, I do this in the css for the text-widget: bind "j" { "move-cursor" (display-lines, 1, 0) }; /* down */ bind "k" { "move-cursor" (display-lines, -1, 0) }; /* up */ bind "l" { "move-cursor" (logical-positions, 1, 0) }; /* right */ bind "h" { "move-cursor" (logical-positions, -1, 0) }; /* left */ but none of these bindings does anything, even if other bindings in the same set are respected. What's especially odd is that the vim-like movement bindings above are respected when I attach them to a GtkTreeView widget for navigating the tree-view options: @binding-set gtk-vi-tree-view { bind "j" { "move-cursor" (display-lines, 1) }; /* selection down */ bind "k" { "move-cursor" (display-lines, -1) }; /* selection up */ } So it seems like there are limitations or overrides of some kind on keybindings for the TextView widget (and for the del key?), but I can't find documentation of anything like that. Are these just things that can't be done with the css providers? If so, what are my alternatives for non-modified keybindings? Thanks.

  • 12.04 Wi-Fi not working correctly with Intel Pro/Wireless 3945ABG

    - by Jerel
    This is a very strange problem. The only time the Wi-Fi works is when I have the wired connection connected. I have a Dell 6400/e1505 with the Broadcom BCM 4401-B0 internal NIC, and the Intel Pro/Wireless 3945ABG Wi-Fi adapter. I was on 10.0.4 LTS before, and I remember having to screw around to get the Wi-Fi to work, but that was years ago, and now it's acting even stranger than it did back then. If I boot up with the wire connected, the Wi-Fi starts up. If I boot up without the wire connected, the Wi-Fi won't start at all. If after booting with the wire connected, and the Wi-Fi starts up, I then disable the wireless, the wired connection works fine. Without the wire connected, dmesg shows the iwl3945 driver loading and starting with no errors, and the wireless adapter activated. Running rfkill list shows no blocks, but there is no connection to my Wi-Fi. Help! I am more confused than a chameleon in a bag of Skittles.

  • RewriteRule not working at server level?

    - by Alexis Wilke
    I wanted to forbid some robots from doing certain things to my websites and decided to add a RewriteRule for that purpose. The rule works when put in one of my <VirtualHost *:80> tag and looks like this: RewriteEngine On RewriteCond %{HTTP_USER_AGENT} libwww-perl RewriteCond %{REQUEST_METHOD} POST RewriteRule . - [F,L] However, I wanted to apply that to all my websites instead of just one of them. So with the newest version of Apache2 settings, I decided to put that code in the security.conf file. This file is defined under /etc/apache2/conf-available/... (and yes, I have a softlink from the /etc/apache2/conf-enabled/... directory.) However, if the definition is only in the conf-available/security.conf files, it somehow gets ignored. From the documentation, it says that these Rewrite* commands all work at server level! Any idea of what I would be missing?

  • Can not resolve hostnames on Xubuntu computers

    - by P Curtis
    I have a network of computers which has been running for many years. I have changed two of those to Xubuntu 11.10 and found I can no longer connect by ssh using the host-name from any other machine. I can connect and ping by IP although ping is very slow in one case (~200ms). All other machines are fine including another with Ubuntu 11.10. Host-name resolution works from Xubuntu machines to other networked machines. I am using wins resolution and have checked settings in /etc/nsswitch.conf are the same as my working Ubuntu systems. What is different in Xubuntu networking that I might have missed?

  • Screen Brightness not adjustable for Acer Aspire S3

    - by Kakadu90
    First of all, thank you very much for providing this useful forum. Too bad for me, there is no support for the Acer Aspire S3 yet (just came out in October) Short Description of the Problem: I cannot adjust the screen brightness. Neither Compiz nor the FN Key combination work. Also the fan keeps running on full power. As you can guess, both of these drain my battery. The Setup: Acer Aspire S3, Intel i5 newest Generation, Intel HD3000 Grafic Accelerator (no driver maybe?) Thanks in advance, Kakadu90

  • Java Not Recognized As Default Application

    - by John
    I just installed java according to this article, and 'java -version' displays java version "1.7.0_07" Java(TM) SE Runtime Environment (build 1.7.0_07-b10) Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode) 'update-alternatives --config java' returns this: There are 2 choices for the alternative java (providing /usr/bin/java).

  • Bluetooth mouse Logitech M555b not recognized on a Macbook Pro 8.2

    - by Pierre
    I just bought a Logitech M555b Bluetooth mouse today. My computer (a Macbook Pro 8,2) has a bluetooth connection, and it works perfectly fine on Mac OSX (I set up a new device, click the connect button on the mouse, and voilà, done in 5 seconds). I cannot get it to work on Ubuntu 12.04. When I follow the same steps as on Mac OSX under Ubuntu 12.04, Sometimes I will see the mouse name appearing for 1 second on the screen, and if I'm fast enough to click on "Continue", I will have a message telling me the pairing with my mouse failed. Here are the steps I follow: Turn off Bluetooth on Ubuntu Turn Bluetooth on. Bluetooth icon Set up new device... Turn on the mouse, and press the Connect button. Press "Continue" on the Bluetooth New Device Setup screen I see the mouse name for one second, but then it disappear. Click on PIN options... to select '0000'. ... nothing, Ubuntu won't see anything. In the /var/log/syslog, I have the following information: May 27 23:26:16 Trane bluetoothd[896]: HCI dev 0 down May 27 23:26:16 Trane bluetoothd[896]: Adapter /org/bluez/896/hci0 has been disabled May 27 23:26:58 Trane bluetoothd[896]: HCI dev 0 up May 27 23:26:58 Trane bluetoothd[896]: Adapter /org/bluez/896/hci0 has been enabled May 27 23:26:58 Trane bluetoothd[896]: Inquiry Cancel Failed with status 0x12 May 27 23:28:26 Trane bluetoothd[896]: Refusing input device connect: No such file or directory (2) May 27 23:28:26 Trane bluetoothd[896]: Refusing connection from 00:1F:20:24:15:3D: setup in progress May 27 23:28:26 Trane bluetoothd[896]: Discovery session 0x7f3409ab5b70 with :1.84 activated I tried for an hour, I restarted my computer, re-paired the mouse on Mac OSX, etc. Sometimes when I restart the computer, I have a dialog box showing up saying that the mouse M555b wants to access some resources or something, if I click "Grant", or even if I tick "always grant access", nothing happens... How can I get the Bluetooth to work properly? Help!

  • IIS Not Accepting Login Credentials

    - by Dale Jay
    I have an ASP.NET web form using Microsoft's boilerplate Active Directory login page, set up exactly as suggested. (See http://msdn.microsoft.com/en-us/library/ms180890%28v=vs.80%29.aspx) Windows Authentication is activated on the "Default Website" and "MyWebsite" levels, and Domain\This.User is given "Allow" access to the site. After entering the valid credentials for This.User on the web form, a popup window appears asking me to enter my credentials yet again. Despite entering valid credentials for This.User (after attempting Domain\This.User and This.User formats), it rejects the credentials and returns an unauthorized user page. Active Directory user This.User is valid, the IP address of the AD server has been verified and SPN's have been set up for the server. Any thoughts as to what may be causing this? I can post code if needed.

  • Newton Game Dynamics: Making an object not affect another object

    - by Boreal
    I'm going to be using Newton in my networked action game with Mogre. There will be two "types" of physics object: global and local. Global objects will be kept in sync for everybody; these include the players, projectiles, and other gameplay-related objects. Local objects are purely for effect, like ragdolls, debris, and particles. Is there a way to make the global objects affect the local objects without actually getting affected themselves? I'd like debris to bounce off of a tank, but I don't want the tank to respond in any way.

  • Tile map collision is not working properly

    I am having problems setting collision between my sprite and the tiles. I have only done the code for colision for moving upwards but some places on the map it moves up and some places it doesn't.

Just a week without travel to get some actual work done.I had plans to blog ambitiously from from Collaborate 10 (Wi-Fi was limited; iPad is still untested), but it's a much busier week than your agenda suggests.Scheduling sessions is one thing: you can count on those chunks of time being lost to the universe. It's the bumping into people in the hall and dropping in on an impromptu lunch that really knocks things out of whack.Good think too: I met with some great folks from

  • Left mouse button not working in Xubuntu session

    - by giodamelio
    I recent changed from Ubuntu to Xubuntu 12.04. The install worked great for a few days, but suddenly the left mouse button stopped working. The right click and scroll bars work fine. After a bit of experimenting I discovered that the problem only happens when I set the session to Xubuntu at login. The mouse also works fine in my dual-booted Windows vista. What could make my mouse stop working like that?
