• OKI-B2540 printer doesn't print?

  - by NCLI

  There is a driver for the OKI-B2520, and it is automatically selected when the printer is connected. From looking at various websites, it seems like the B2500, B2520, and B2540 all work perfectly fine with the OKI-B2520 driver, so I let it install that. Everything went smoothly, the printer shows up as available, and I can queue jobs without any problems, and they disappear after a few seconds. However, nothing actually comes out. There is no error message on the printer display, or from Ubuntu. This is the output from the CUPS error log: http://pastebin.com/S6ifZAup So my question is: What is wrong??

• Unity3D 3.5 pro - Moving the camera vs setting draw distance

  - by stoicfury

  I move the camera mostly via right-click + WASD, sometimes with [shift] if I want it to move faster. Occasionally, instead of moving my camera, it alters the draw distance / FOV / some visual aspect of the editing scene that causes trees and other object to disappear when I scroll enough, and eventually even the terrain starts disappearing. It is not m "zooming out". My camera does not move, the width and height of the FOV stays the same (one might say the depth is being altered though). What key am I hitting to cause this to happen, and is it possible to disable it? side note: "keybinds" is probably the most spot-on tag for this question but it doesn't exist (surprisingly) and I lack the rep to create it.

• OcclusionQuery: how to ignore some objects?

  - by ApocKalipsS

  I'm trying to make a LensFlare effect when the player watch the sun in my XNA 4.0 Game. To do this, I use OcclusionQuery, here's my code: http://pastebin.com/meAkdwmD I also have some models, a terrain and a skybox. Here's my main Draw code: terrain.Draw(); model1.Draw(); model2.Draw(); skybox.Draw(); lensFlare.UpdateOcclusion(); lensFlare.Draw(); The problem is that the occlusion considers the sun to be behind the skybox, and the lensFlare wasn't showing up. So I moved lensFlare.UpdateOcclusion() before the drawing of the Skybox, and now the lensFlare appears, but my skybox is blinking (it's like it disappear and reappear at each frames...) How do I ignore the skybox in the occlusion?

• Finding a publisher for Windows Phone Marketplace - I'm from an unsupported country

  - by Axarydax

  Hello,I'd like to develop apps for Windows Phone 7,but I can't register at AppHub,because my country (Slovakia) is not supported. A guy from Microsoft said that I need to find someone under whom I'd publish those apps. Where would I find somebody who'd be willing to register there and basically act as my publisher? I'm risking that he'd take my app earnings and disappear if it's not an honest person. What would the "publisher" risk by signing his name under my apps? Or are any of you willing to do it?

• How to stop running pidgin at logins and disable window hiding feature?

  - by Behzadsh

  Every time I login into my desktop, pidgin start behind, and sometimes it's bothering me - e.g. when I'm not connected to Internet or when I don't want to be on-line - I check startup application list and there's no pidgin listed. another thing that is very bothering is hiding window feature or what ever it called. assume that you're using MusicTracker plug-in, your status is Busy and you're chatting with someone. when music change, status will change, and then buddy-list will disappear and chat window will minimize. Buddy-list is not important but minimizing chat window when you're chatting is bothering, Is there any way to make pidgin stop that?

• Z-index preventing on hover attribute on another element [migrated]

  - by user18294

  I have two different elements (div class="") within a larger container. Let's call them div class="overlay_container" and div class="title." The div class="overlay_container" has a subclass, .image, which creates an overlay over the entire larger container on hover. The div class="title" has a z-index of 10,000 and lies over .image and therefore over the overlay. Unfortunately, when you hover over "title," the subclass overlay image underneath disappears. I know the problem is obviously that the "title" div is right over the other divs and therefore the on hover will disappear due to the z-index. But how do I fix this? How do I make it so that when you hover over the "title," the .image overlay still appears? If your answer involves jQuery, could you please tell me where to put the script (before the /head tag)? Thanks!

• How do I recover files from U1 cloud

  - by MarkWW

  OK I have just stopped syncing a folder. This appears to have been a huge mistake. I did not realise the folder would disappear from my cloud storage. I assume (and hope) the sub-folders/files it contained still exists in the cloud. I hope they still exists in the cloud because they do not exist on my computer. I did not delete these files from the cloud (I have tried to recover deleted files - none are being recovered). Where are they and how do I get them back into My storage?

• Problems after upgrading to 14.04 (only background and pointer after login)

  - by fabikw

  After upgrading from 12.04 to 14.04 I could log in to my X session (albeit with really low graphics). While trying to fix the graphics, I managed to break the X session. Now, after typing my password in the unity-greeter, the items disappear and I can only see the desktop background and the pointer. This happens for every user. I can still log in in tty's. How can I solve this? Also, I cannot seem to be able to install nvidia-current as it tries to install nvidia-304 and it depends on old video-abi libraries. Is there a way to tell the package manager that nvidia-current should use a newer version?

• After power manager reinstall

  - by tuxi

  I had checking battery state hanging I solved it with the help of an answer from this site: sudo apt-get --reinstall install gnome-power-manager But now my left windows bar is rigid, it does not disappear on wide screen. EDIT Also in most of applications, characters are white. What could be the problem? and what should I do? 2ND EDIT My ubuntu is 12.04 LTS. I was trying to install some packages for dependencies of allegro game development library, one of the packages was libwxgtk2.8-0, after that a red cross appeared near user name and clock. Then computer became frozen and i had to remove my battery. I know it is a very bad thing. Then when i try to restart my computer, it could not start, it was waiting on black screen with line: Checking battery state... Then i run the above command. Computer could start but characters are white.

• Networking Icon Keeps Disappearing

  - by Zelda64fan

  Almost every time I unlock my computer the networking icon and the Bluetooth icons are missing from the panel. They also disappear if I disable networking with the 'hardware switch', even though before they would just switch to a 'disabled' look. I know I can get the networking one back by running nm-applet, but I'd rather just find a way to make it stop disappearing. What causes this? This is on 12.10 64-bit, if it matters. UPDATE: I ran it from terminal, and got this: $ nm-applet ** Message: applet now removed from the notification area ** Message: PID 31340 (we are 28924) sent signal 15, shutting down... And then it exited. So it thinks it's supposed to quit...? I haven't been able to figure out what process had that ID.

• Why do packages fail to install from command line

  - by calebB

  Every once in a while I can't install packages in Ubuntu 11.04. I'll try to run the software center and it and it will pop up then disappear. If I call it from the command line it says it seg-faults. And then trying to install anything from the command line I get this: sudo apt-get install pdftk Reading package lists... Done And thats all I get for anything I try. Usually restarting fixes the problem but its very annoying.

• Drawing line from sprite with a touch

  - by Kaizer

  I am working with cocos2d for the iPhone and I have a question about how to implement the following. I have a circle shaped sprite on my layer. When I touch the sprite and move my finger a line must be drawn from the sprite to where my finger is. When I move my finger on the screen the line must follow (straight line). When I release my finger the line should disappear. In a good looking way I should be able to restyle the line into an arrow. Can anyone move me in the right direction for this ? Kind regards

• Less known Solaris features: pwait

  - by user13366125

  This is a nifty small tool that i'm using quite often in scripts that stop something and do some tasks afterwards and i don't want to hassle around with the contract file system. It's not a cool feature, but it's useful and relatively less known. An example: As i wrote long ago, you should never use kill -9 because often the normal kill is intercepted by the application and it starts to do some clean up tasks first before really stopping the process. So just because kill has returned, it doesn't imply that the process is away. How do you wait for process to disappear? (more)

• trigger jQuery function after location.reload() completes

  - by raj

  I have a Rails app that allows users to login via jQuery modal form. Once logged in, I refresh the original page using location.reload(). At this point, I'm attempting to create a new jQuery dialog. How can I open the dialog only after location.reload() has finished executing? Right now the dialog is loading up before location.reload() is done. This is causing the dialog to disappear.

• When to use weak references in Python?

  - by bodacydo

  Can anyone explain usage of weak references? The documentation doesn't explain it precisely, it just says that the GC can destroy the object linked to via a weak reference at any time. Then what's the point of having an object that can disappear at any time? What if I need to use it right after it disappeared? Can you please explain them with some good examples? Thanks, Boda Cydo.

• MKMapView Not Loading When Called on an NSThread?

  - by Chris

  I am creating a MKMapView in a method named "generateMap". From inside viewDidLoad, this works: [self generateMap]; but this causes the map to quickly load and then disappear, leaving only the blank grey grid: [NSThread detachNewThreadSelector:@selector(spinTheSpinner) toTarget:self withObject:nil]; Any ideas why this might be happening when I call the method through a thread?
