• How do I make Ubuntu go past the splash screen?

  - by John Baber

  I recently upgraded my desktop mac to Precise and now can't get past the Ubuntu 12.04 splash page. The splash freezes with ubntu and the dots turning from white to orange forever. This is when I choose 3.2.0-generic from the grub menu. If I choose to load up older kernels, I still get the same thing. How can I make my computer finish booting again? I'm able to ssh into the machine and poke around, but the actual screen freezes at the splash. dmesg cat kern.log

• Results stored in a session - good idea?

  - by Nick

  To give a bit of background, lets say it's a generic results page, which is paginated so there are X results per page. Generally to do this, I have two queries on the page: to get the total number of results to get the results, limiting by the correct page's resultset However, recently I've been trying to cut down on the queries the site is making, and I thought one way to do this would be to only do the query if any parameters to the page have changed (except of course the page number)? This would then cache all the result id's in a session, which can be sliced when I need to return the correct resultset for that page. I was trying to look around the net to see if there are downsides of this method, but I've found very little information about it. Has anyone done this before? Is it a good idea?

• Apple wireless mouse and keyboard doens't work

  - by drigoSkalWalker

  I paired the mouse and keyboard on ubuntu, but it seems not work. I got this error in /var/log/syslog kernel: [ 1875.935712] input: Apple Magic Mouse as /devices/pci0000:00/0000:00:12.0/usb4/4-3/4-3:1.0/bluetooth/hci0/hci0:2/input34 kernel: [ 1875.935885] evdev: no more free evdev devices kernel: [ 1875.935893] input: failed to attach handler evdev to device input34, error: -23 kernel: [ 1875.936049] magicmouse 0005:05AC:030D.0003: input,hidraw0: BLUETOOTH HID v3.06 Mouse [Apple Magic Mouse] on 00:19:5D:0F:4A:F6 kernel: [ 2334.787710] input: Apple Wireless Keyboard as /devices/pci0000:00/0000:00:12.0/usb4/4-3/4-3:1.0/bluetooth/hci0/hci0:4/input36 kernel: [ 2334.787729] evdev: no more free evdev devices kernel: [ 2334.787737] input: failed to attach handler evdev to device input36, error: -23 kernel: [ 2334.787999] generic-bluetooth 0005:05AC:0255.0005: input,hidraw1: BLUETOOTH HID v0.50 Keyboard [Apple Wireless Keyboard] on 00:19:5D:0F:4A:F6 Nothing appears in xinput --list, only the wired mouse and keyboard.

• How do I suppress the "New release '12.10' available" message?

  - by cjm

  When I ssh into my Mythbuntu box, I get this message: Welcome to Ubuntu 12.04.1 LTS (GNU/Linux 3.2.0-32-generic x86_64) * Documentation: https://help.ubuntu.com/ New release '12.10' available. Run 'do-release-upgrade' to upgrade to it. Last login: <redacted> $ But I don't intend to upgrade to 12.10, because Mythbuntu recommends using LTS releases only. How do I suppress the "New release '12.10' available" message? I don't want to be notified until the next LTS release is available. I've already gone to Update Manager Settings Updates and selected "Notify me of a new Ubuntu version: For long-term support versions", but that didn't get rid of this message.

• Where can I find good (well organized) examples of game code?

  - by smasher

  Where can I find good (well organized) examples of game code? I'm hoping that I can pick up some organizational tips. Most examples in books are too short and leave out lots of detail for the sake of brevity. I'm particularly interested on how to group your variables and methods so that another programmer would know where to look in the code. For example initializers at the top, then methods that take input, then methods that update views. I don't care about a particular language, as long as its OOP. I looked at the Quake 2 and 3 sources, but they're straight C and not much help for getting tips on organizing your objects. So, have you seen some good source? Any pointers to code that makes you say "wow, that's well organized" would be great.

• Cannot save all of the property settings for this Web Part.

  - by ybbest

  I would like to display all the items of custom content type of Animals in a SharePoint content query WebPart. After choosing the appropriate values in the web part editor and click on Save I got this error: Cannot save all of the property settings for this Web Part. There is a problem with one or more of the field values below. But when I examine all the values below , it does not flag any error information. I finally manage to locate the error flag after I expand the presentation section. I then delete the text in the Link textbox , now I can save the settings. However , I think the error message should have been more specific so that users can quickly locate the error. The worst part for this is that I did not even change anything in the presentation section, I merely configure the Source in the Query section. Well, I guess I am still new to SharePoint, I just have to get used to these generic error message ):

• game engine done, ideas missing

  - by Thoms

  I read at many places how people have this GREAT ideas but are not able to program themselves. I have quite the opposite problem. I have developed game engine, level editor, embedded Lua scripting language, I have even made wrapper for Android and it all works well. But I have no good idea about how to proceed with actual levels; I have no good ideas. The engine itself is very generic and can be used in many game concepts, but I just cannot think of anything useful. Do you have any thoughts on how to proceed? Where should I seek ideas? Who should I ask? I am sorry if this question is a duplicate.

• Ubuntu 12.10 install freezes at configuring hardware

  - by Max Keener

  I'm installing Ubuntu 12.10 (64 bit) from a bootable USB stick. At first I had trouble with a black screen after selecting 'install ubuntu'. I added nomodeset and xforcevesa to the options to fix that problem. Now when installing, it hangs at 'Configuring Hardware', specifically at ubuntu ubiquity: update-initramfs: Generating /boot/initrd.img-3.5.0-17-generic Specs: Asus UX32a DB51 Intel Core i5 3317U 1.7 GHz 4GB DDR3 RAM intel hd 4000 graphics 500 GB harddrive with 25 GB sandisk ssd I'm trying to install Ubuntu by itself right now on the SSD. I made custom partitions (100 mb EFI boot partition, 4GB swap space, 20GB ext4 mounted on '/') I've tried re-downloading the ubuntu iso and creating a new boot image on my flash drive and it results in the same problem. Thanks in advance for the help!

• Shouldn't all source code be plain text? [on hold]

  - by user61852

  Some developing environment/languages save the source code you write in a binary/propietary format that you cannot see or edit with a generic text editor. I'm not talking about compiled code, but the source code. An example could be PowerBuilder and Oracle Forms. It's ok you use proprietary technology if you want, but not being able to open the source code you wrote, in a simple editor, if only to read it, seems like a very strict form of vendor lock-in. Also this prevents you from using text-based version controls that can show you the difference between two versions in a line-by-line base. If the code is plain text, you don't need a license in order to just open it, see it and learn from it. Should it be a golden rule to avoid vendor lock-in to avoid technologies that save your source code to anything but plain text files ?

• Best practice for comments above methods in a grails application?

  - by Travis

  I'm writing a grails application and am not sure what the best practice is with regard to comments outside of method blocks. I've done a bit of research and there seems to be conflicting views on how and when these sort of comments should be used. In lots of source code I have seen there seems to be comments above every method detailing what that method does. I'm not sure if grails should be differnet? My question is should I have a comment above each method in my controllers, services and domain objects? i.e /* * This method displays the index page */ def index(){ render view : "index" }

• Installing multiple ubuntu partitions on same machine without corrupting GRUB

  - by LGB

  I had only ubuntu installed on my pc, but I felt like adding another ubuntu (same version) partition so I could have one just for work/study and another one just for personal generic use. I installed it and it worked out okay, but I found I needed more space on the new created Ubuntu partition, so I booted up from the Live CD, and used GParted to move/shrink/grow the partitions as the Ubuntu's tutorials suggested it was pretty straightforward. But in doing all this I messed up with Grub, so when I start my system it shows: error: unknow filesystem grub rescue What would be the easiest way to recover it so I could have both partitions working? Btw, it wouldn't be a problem for me to lose the partitions if it's the shortest/easiest way. Thanks in advance.

• Dell b1160w not working in 14.04

  - by mission007

  I originally installed the dell b1160w printer on ubuntu 12.04. It worked as expected. A few months ago I upgraded to ubuntu 14.04 and now I can't get the printer to work. I looked at the driver information on the dell site. They have not updated their driver since 2013 so 12.04 is the latest version with a supported driver. Is there a work around for this problem, like a generic driver that I can use or a way to install whatever printer interface ubuntu 12.04 was using? I have a windows virtual box. I can get it to work through there, but it's inconvenient to pull up my virtual box and transfer the files over to it anytime I want to print.

• Scammers on the lose pretending to be Microsoft

  - by John Paul Cook

  Minutes ago I received a phone call that the caller ID listed as “Out of area”, which I knew was a bad sign. It was difficult to understand the caller because of his very thick accent. He told me that he was from Microsoft and that my computer was throwing a large number of errors and he was calling to help me. He directed me to use Windows R to open a run dialog box, type eventvwr and then look at the Event Viewer. Within Event Viewer, he instructed me to open Custom Views and then open Administrative...(read more)

• How can I use a CanoScan N640Pex scanner over a USB/parallel cable?

  - by detly

  I have an old CanoScan N640Pex flat bed scanner and a USB-to-parallel port cable through which I can connect it to my PC. Unfortunately neither Simple Scan nor XSane detect the scanner. I'm running Ubuntu 12.04 (plus updates and backports) with kernel 3.2.0-31-generic. dmesg tells me this when I plus the cable in: [256411.641910] usb 7-1: new full-speed USB device number 10 using uhci_hcd [256411.872392] usblp0: USB Bidirectional printer dev 10 if 0 alt 1 proto 2 vid 0x067B pid 0x2305 [256411.872417] usbcore: registered new interface driver usblp lsusb shows this device for my cable: Bus 007 Device 010: ID 067b:2305 Prolific Technology, Inc.

I suspect I might need to change something in /etc/sane.d/canon_pp.conf, but I have no idea what to put for the ieee1284 line, since there is pretty much zero documentation for that parameter. So how can I get it to work?

• Alps touchpad detected as a mouse, can't enable/disable multitouch

  - by Shota Bakuradze

  Now I know that this has been asked several times here but I couldn't find any decent solution to it. I am running Ubuntu 12.04 on my DELL N5110 and my touchpad is detected as a mouse, So I don't have the touchpad options availiable. Can't use multitouch and can't disable it either. I have tried the dkms driver from this link. But when I tried to install it with dpkg -i command, dpkg returns the following error: ERROR (dkms apport): unable to determine source package for psmouse-alps-dkms Error! Bad return status for module build on kernel: 3.2.0-25-generic-pae (i686) Consult /var/lib/dkms/psmouse-alps/0.10/build/make.log for more information. I have installed all the updates as well. Can someone help me out with this issue?

• How can I solve display glitches and poor performance with ATI fglrx driver on my ThinkPad X100e?

  - by rewbs

  Hi all, I noticed that video performance on my Thinkpad X100e was very poor compared to Windows 7, so I installed the ATI fglrx proprietary drivers by using the "Additional Drivers" dialogue box. The system has an ATI Radeon Mobility HD 3200 chip. The result of installing the drivers is pretty devastatingly negative, with symptoms such as skewed content in windows, browser tabs and text boxes failing to refresh when their content changes. In fact, please excuse typos in this post, because I can't really see what I am typing. :) I also notice that HD video playback performance is no better - perhaps even worse - than prior to installing the drivers. Example of what I see: Here's the output of fglrxinfo: display: :0.0 screen: 0 OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: ATI Radeon HD 3200 Graphics OpenGL version string: 3.3.10237 Compatibility Profile Context Output of lspci | grep -i vga: 01:05.0 VGA compatible controller: ATI Technologies Inc RS780M/RS780MN [Radeon HD 3200 Graphics] I'm on Ubuntu 10.10 with kernel 2.6.35-22-generic-pae. What can I try? Many thanks, -R

• What set of tools make up "the rails way" of testing javascript in the browser?

  - by Jordan Feldstein

  What's the concensus for doing in-browser (either headless or remote-controlled) testing of javascript? Unit testing my JS is nice, but can't protect against irresponsible changes to the DOM. Unit testing of the JS and functional testing of the views to make sure they both provide and utilize the same, correct DOM, might work, but then the link between JS and DOM is being covered in two places which seems brittle or cumbersome. Is there an acknowledged "Rails Way" to implement full-stack tests, where I can run my javascript against the DOM rendered by the rest of the app, and check the results? (Something like what PHPUnit and Selenium give us, but inside the rails framework?)

• Line6 UX1 soundcard and Ubuntu

  - by the_drow

  I own a Line6 UX1 soundcard and I would like to make it work for Ubuntu. I have followed the instructions here and it worked. But at some point I upgraded my kernel version (not sure what uname -a prints but it's related) and it stopped working. Here's what uname -a prints: Linux ubuntu 2.6.32-29-generic 58-Ubuntu SMP Fri Feb 11 20:52:10 UTC 2011 x86_64 GNU/Linux I figured out that maybe it's installed per version so I used svn update and hit make again. My guess was right as it copied the relevant files to the new version's folder. I restarted and still nothing. Should I revert to an older version? Or is there a solution here?
