How do I get an Canon Pixma MP150 to print?

- by Radu Erdei

I succesfully installed my Canon Pixma MP150 printer (and scanner) in Ubuntu 12.04, made it the default printer, but i cannot print anything. Watching the printing queue, i see that the printer receives my documents but just for a few seconds after which the queue gets empty without anything getting actually printed. I tried to print from large pdf's to quite tiny txt files. I reinstalled the printer from cups web-based interface (127.0.0.1:631) but again, no luck. Any ideea on the matter?

How to troubleshoot ethernet port on laptop

- by Psallas Vassilios

I have a problem with my wired connection. To be more specific, my laptop doesn't seems to recognize that I have plugged in an ethernet cable. I tried to download new drivers for my ethernet card, but I couldn't find any solutions. Maybe because I am new to Linux, so I'm not familiar with running commands in the terminal. OK I have typed the command and here are the results: 00:04.0 Ethernet controller [0200]: Silicon Integrated Systems [SiS] 191 Gigabit Ethernet Adapter [1039:0191] (rev 02) For the second reply I don't know if the following is what you asked me: ?Memory: 3.9 GiB ?Processor: Intel Core 2 Duo CPU P8800 @ 2.66GHz × 2 ?OS type: 32-bit My Ethernet connection had some problem on Windows too. I have changed recently my internet provider, and since then my ethernet cable is not recognized by the laptop. At that time I was still on Windows. I thought that with Ubuntu the problem would be solved, but unfortunately the problem still persists. If someone can help me to solve my problem I'll be thankful. Here are the results of the three first commands you told me to run: lsmod | grep sis190 sis190 22570 0 sudo modprobe sis190 ifconfig eth0 Link encap:Ethernet HWaddr 00:90:f5:90:81:7e UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:185 errors:0 dropped:0 overruns:0 frame:0 TX packets:185 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:22672 (22.6 KB) TX bytes:22672 (22.6 KB) wlan0 Link encap:Ethernet HWaddr 00:25:d3:2c:3a:ae inet addr:192.168.1.72 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::225:d3ff:fe2c:3aae/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:260 errors:0 dropped:0 overruns:0 frame:0 TX packets:363 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:71992 (71.9 KB) TX bytes:52000 (52.0 KB) and the results of running the last two commands: dmesg | grep -e eth -e sis190 [ 0.816667] sis190: sis190 Gigabit Ethernet driver 1.4 loaded [ 0.816728] sis190 0000:00:04.0: setting latency timer to 64 [ 0.816751] sis190: 0000:00:04.0: Read MAC address from EEPROM [ 0.904032] sis190: 0000:00:04.0: Realtek PHY RTL8201 transceiver at address [ 1.416030] sis190: 0000:00:04.0: Using transceiver at address 1 as default [ 1.448235] sis190 0000:00:04.0: eth0: 0000:00:04.0: SiS 191 PCI Gigabit Ethernet adapter at f8410000 (IRQ: 19), 00:90:f5:90:81:7e [ 1.448238] sis190 0000:00:04.0: eth0: GMII mode.

Read Committed Snapshot Isolation– Two Considerations

- by GavinPayneUK

The Read Committed Snapshot database option in SQL Server, known perhaps more accurately as Read Committed Snapshot Isolation or RCSI, can be enabled to help readers from blocking writers and writers from blocking readers. However, enabling it can cause two issues with the tempdb database which are often overlooked. One can slow down queries, the other can cause queries to fail . Overview of RCSI Enabling the option changes the behaviour of the default SQL Server isolation level, read...(read more)

Additional Columns in StreamInsight Event Flow Debugger

This tool is excellent when investigating what is going on in your StreamInsight Streams. I was looking through the menu items recently and went to Query => Event Fields I found that there were a couple of columns not added by default to the event viewer (Reminds me of the fact that the Variables viewer in SSIS hides columns also) Latency NewEndTime EnqueueTime Here they all are together. This gives us even more information about what is going on

LTSP thin client to single user mode

- by DJC

Is it possible to boot a LTSP thin client to single user mode? I've updated the default entry under /var/lib/tftpboot/ltsp/i386/pxelinux.cfg to read as follows: - append ro initrd=initrd.img root=/dev/nbd0 init=/sbin/init-ltsp nomodeset quiet splash **single** plymouth:force-splash vt.handoff=7 nbdroot=:ltsp_i386 This kind of works! I see the boot progress to the point where it asks me to either enter the root password or Ctrl+D to bypass. However, the boot process just seems to continue without providing an chance to do either.

Re-generating SQL Server Logins

SQL Server stores all login information on security catalog system tables. By querying the system tables, SQL statements can be re-generated to recover logins, including password, default schema/database, server/database role assignments, and object level permissions. A comprehensive permission report can also be produced by combining information from the system metadata.

How can I get GRUB to appear after insallting Ubuntu with Windows 7 using a LiveUSB?

- by Niall

I booted Ubuntu 12.04 LTS from a LiveUSB, and then selected the option to install Ubuntu to my hard drive. I allowed the installer to partition it, giving Ubuntu 50GB and leaving Windows 7 with 200GB. However, when I boot I still boot straight into Windows: the only way to access GRUB is by booting from the LiveUSB, although this can then be removed. How do I access the GRUB menu by default before booting windows without using the USB?

Is it possible to auto-arrange the active Unity launcher icons?

- by tijybba

I am using Ubuntu 12.04 x64 bit as default DE. I was guessing it is possible to Auto Arrange the Current-Active applications in Unity Launcher panel to align in Lastly-Opened or Firstly-Opened in ascending or descending order, irrespective of their locked positions in the Unity Launcher panel. Just to get rid of Scrolling down the launcher panel every time to search active application thereby depriving the need of Alt-Tab shortcut. I mean Alt-Tab alternative in more smarter way, though I also use Alt-Tab for the task Management purpose.

Why does the login screen fail to appear?

- by a different ben

My system: Dell Precision T3500 nVidia Quadro NVS 295 Ubuntu 12.04 x86_64 (3.2.0-32) Essential problem: On boot my system won't get past the splash screen. I can switch to another virtual terminal and log in, I can also ssh from another system -- so it appears that the problem might be with the display manager. How can I diagnose and fix this problem? More info: From a VT I can issue sudo lightdm restart, and this will bring up the login screen and and I can continue from there. So I do have access to my system. Update-manager recently updated a number of packages, including a bunch of x11 and xorg packages, some nVidia drivers, rpcbind, etc etc. My boot log (if that is any guidance) says the following: fsck from util-linux 2.20.1 fsck from util-linux 2.20.1 fsck from util-linux 2.20.1 fsck from util-linux 2.20.1 rpcbind: Cannot open '/run/rpcbind/rpcbind.xdr' file for reading, errno 2 (No such file or directory) rpcbind: Cannot open '/run/rpcbind/portmap.xdr' file for reading, errno 2 (No such file or directory) /dev/sda1: clean, 597650/1525920 files, 3963433/6103296 blocks /dev/sda7: clean, 11/6406144 files, 450097/25608703 blocks /dev/sda5: clean, 158323/1525920 files, 1886918/6103296 blocks /dev/sda8: clean, 250089/107929600 files, 111088810/431689728 blocks Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox Skipping profile in /etc/apparmor.d/disable: usr.sbin.rsyslogd * Starting AppArmor profiles [80G [74G[ OK ] Loading the saved-state of the serial devices... /dev/ttyS0 at 0x03f8 (irq = 4) is a 16550A * Starting ClamAV virus database updater freshclam [80G [74G[ OK ] * Starting Name Service Cache Daemon nscd [80G [74G[ OK ] * Starting modem connection manager[74G[ OK ] * Starting K Display Manager[74G[ OK ] * Starting mDNS/DNS-SD daemon[74G[ OK ] * Stopping GNOME Display Manager[74G[ OK ] * Stopping K Display Manager[74G[ OK ] * Starting bluetooth daemon[74G[ OK ] * Starting network connection manager[74G[ OK ] * Starting Postfix Mail Transport Agent postfix [80G [74G[ OK ] speech-dispatcher disabled; edit /etc/default/speech-dispatcher * Starting VirtualBox kernel modules [80G [74G[ OK ] * Starting the Winbind daemon winbind [80G [74G[ OK ] saned disabled; edit /etc/default/saned * Starting anac(h)ronistic cron[74G[ OK ] * Stopping anac(h)ronistic cron[74G[ OK ] * Checking battery state...

How to make PPA build for particular release

I'm creating my first proper PPA to patch a problem with Compiz. debbuild/dput works fine but Launchpad tells me it's only building it for Quantal. I've no interest in doing that for the minute - I'd like it to build for Precise. What do I need to do to get this done? Edit: I went into the package page in Launchpad and managed to copy the package I uploaded for another release, but is there a way of setting the default release(s) for a PPA?

The Minimalist Approach to Content Governance - Create Phase

- by Kellsey Ruppel

Originally posted by John Brunswick. In this installment of our Minimalist Approach to Content Governance we finally get to the fun part of the content creation process! Once the content requester has addressed the items outlined in the Request Phase it is time to setup and begin the production of content. For this to be done correctly it is important the the content be assigned appropriate workflow and security information. As in our prior phase, let's take a look at what can be done to streamline this process - as contributors are focused on getting information to their end users as quickly as possible. This often means that details around how to ensure that the materials are properly managed can be overlooked, but fortunately there are some techniques that leverage our content management system's native capabilities to automatically take care of some of the details. 1. Determine Access Why - Even if content is not something that needs to restricted due to security reasons, it is helpful to apply access rights so that the content ends up being visible only to users that it relates to. This will greatly improve user experience. For instance, if your team is working on a group project many of your fellow company employees do not need to see the content that is being worked on for that project. How - Make use of native content features that allow propagation of security and meta data from parent folders within your content system that have been setup for your particular effort. This makes it painless to enforce security, as well as meta data policies for even the most unorganized users. The default settings at a parent level can be set once the content creation request has been accepted and a location in the content management system is assigned for your specific project. Impact - Users can find information will less effort, as they will only be exposed to what they need for their work and can leverage advanced search features to take advantage of meta data assigned to content. The combination of default security and meta data will also help in running reports against the content in the Manage and Retire stages that we will discuss in the next 2 posts. 2. Assign Workflow (optional depending on nature of content) Why - Every case for workflow is going to be a bit different, but it generally involves ensuring that content conforms to management, legal and or editorial requirements. How - Oracle's Universal Content Management offers two ways of helping to workflow content without much effort. Workflow can be applied to content based on Criteria acting on meta data or explicitly assigned to content with a Basic workflow. Impact - Any content that needs additional attention before release is addressed, allowing users to comment and version until a suitable result is reached. By using inheritance from parent folders within the content management system content can automatically be given the right security, meta data and workflow information for a particular project's content. This relieves the burden of doing this for every piece of content from management teams and content contributors. We will cover more about the management phase within the content lifecycle in our next installment.
