• Binfmt config not persisting after booting

  - by Ishpeck

  I have the binfmt kernel module set up so I can run .NET apps as if they were native binaries. I have the /etc/rc.local file configured identically to this. If I power down my computer or boot into Windows, when I come back to Ubuntu, I can't run .NET apps without calling Mono. However, if I simply touch /etc/rc.local and restart, the binfmt configuration appears to kick in and I can run my .NET EXE's as I expect to. How do I get my configuration to stick?

• Can't connect to wireless without typing sudo modprobe b43 in terminal

  - by user90889

  I just upgraded to 12.04 on an old ACER Travelmate 5320 using Broadcom 4311. I wasn't able to connect to the internet through the wireless for a few days. It didn't even display wireless networks. I was finally able to make it work by following the instructions found here: http://linuxwireless.org/en/users/Drivers/b43#supported However, each time I log on to the computer I have to go to the terminal and type sudo modprobe b43 to make the wireless work. Is there somehow I can avoid this? I have used Ubuntu for many years but always relied on other people to help me with the technical stuff. The terminal is alien to me so I literally follow online forum instructions without knowing what I'm doing. Also, I tried many many things before I managed to make it work. So I'm worried I may have installed something that now conflicts with whatever the sudo modprobe b43 does. Thank you

• External monitor with NO mouse cursor

  - by Csaba Nyerges

  I am using a Fujitsu Siemens Amilo L7310 laptop computer with an external monitor. I'm wishihg to use version 10.04. The problem is, when I plug my laptop into the external monitor with my laptop screen turned either on or off, I do not see the mouse cursor on the external monitor! The mouse cursor is still there, although invisible. If I connect the external monitor to my laptop before swithing both on, the same happens. Is there any solution to make the cursor appear on the monitor?

• Ubuntu 12.10 64 bit Slow

  - by Patrick Skiba

  I am new to linux and was wondering why launching applications is so slow. I've tried both Ubuntu 12.10 64 bit and Ubuntu 12.04 LTS 64 bit Computer Specs: Toshiba Satellite p755 CPU: Intel core i7-2670QM @2.20GHz Ram: 8 GB Using integrated intel hd 3000 graphics When I install the first thing I do is update, which takes about an hour or so. I would assume I'd be good after that, but when launching things like the firefox, system settings, thunderbird it takes a much much longer time than on Windows 7. Please help me.

• How to make Bumblebee work with HP Pavilion DV6T-7000 Quad Edition with Intel HD 4000 and Nvidia GeForce GT 650M 2GB?

  - by user69469

  I just recently bought a HP DV6T-7000 Quad Edition. It has an Intel HD 4000 and a Nvidia GeForce GT 650M 2GB with Optimus. I read that I could use bumblebee to make optimus work, so I installed it. I also installed bumblebee-nvidia and nvidia-current from the ubuntu-x-swat/x-updates ppa. I rebooted, but when I tried to run anything with optirun, the computer would wait ten seconds or so, then do a hard shutdown. I got no log messages from bumblebee, Xorg, or optirun, either. I have purged and reinstalled bumblebee, bumblebee-nvidia, and nvidia-current. I have also set the turned off power management in the bumblebee.conf file to no avail. I am out of ideas about this, and I need both options. Any ideas would be much appreciated.

• SPARC T5-4 Engineering Simulation Solution

  - by Mike Mulkey-Oracle

  A recent Oracle internal performance evaluation for computer-based product design demonstrated that Oracle's SPARC T5-4 server running MSC's SimManager simulation software with Oracle Database 12c consolidates the work of multiple x86 servers while delivering better overall performance.   Engineering simulation solutions have taken the center stage in helping companies design and develop innovative products while reducing physical prototyping costs, and exploring a larger design space, resulting in more design possibilities. For this solution, a single SPARC T5-4 server running Oracle Solaris 11 was deployed to consolidate the MSC SimManager server, the Oracle Database 12c server, and the web application server onto a single platform. An automotive design workload was deployed to demonstrate how the SPARC T5-4 server can be used to consolidate the work of multiple x86 servers and deliver better overall performance while reducing complexity and achieving optimal product designs.  A joint Oracle/MSC Software solution brief describes this in more detail:  A Simplified Solution for Product Lifecycle Management —MSC SimManager on a SPARC T5-4 Server

• Encryption Password help!

  - by Carlos L.

  Ok so let me summarize this up. I encrypted my Home to protect against hackers of course when I first installed Ubuntu. It loaded up the Terminal and was attempting to show me my encryption password incase it ever needed to be used. So I thought "Ehh what the heck, I can find it out later..." So I closed Terminal and went on with the (amazing!) Ubuntu life. But now I am having to install Java JDK 7.0.0.4 onto my computer to ya know, play games and such. But it is asking for my password for the encrypted Home folder but it never gave it to me... HELP!!! Does anyone remember the command for Terminal to give you you're randomly generated Encryption password pop up on the famous purple window? Please give legitimate answer and fast please!

• Managing a remote ubuntu server

  - by erdomester

  I hire an Ubuntu server which I access remotely and I purchased a domain for my webpage. I am totally new to this server thing and to Ubuntu as well. What applications should I install on the server? I need to transfer files to the server, I guess I would use FileZilla the same way I use it to upload files to my free website. But to have a username and password should I install an ftp server and create a user on Ubuntu? My website will send automated messages to users, so do I need to install a mail server as well? What other software should I install on the server apart from a firewall and an anti-virus? Should I partition the hard drive (3TB) and how? How partitions should I create and in what size for what applications? Btw I use Windows 7 on my computer, so I am basically a windows user.

• Ubuntu Software Center is crashing while trying to install psychonauts

  - by GonzoDark

  I am having a problem installing Tim Schafers epic platform video game Psychonauts trough the Ubuntu Software Center. I have bought the game on http://www.humblebundle.com/ and I have used the new redeem option introduced in this bundle: "redeem your bundle on the Ubuntu Software Center." When I have downloaded approximately 2.1 GB of Psychonauts then Ubuntu Software Center starts to repeatedly crash and pop-up with a new crash report dialog every few seconds (before previous ones are closed and that will crash the computer after a few min, unless I stop the download). I also have a file-size bug, where Ubuntu Software Center tells me that I have downloaded 880,2 MB out of 133,3 MB I use the new Ubuntu 12.04 LTS and Ubuntu Software Center version 5.2.2.2 (©2009-2011 Canonical <--- That is also a bug, should be 2012 I guess) I hope someone can help me.

• Xubuntu and other Debian based distros slow

  - by William V

  I have a Compaq Presario SR1950NX desktop computer with the AMD64 3800+ processor and 1GB ram and it seems that Ubunutu, Xubuntu and Lubuntu are all laggy. Things seem to be slow such as clicking on menus and opening programs and the UI renders in peices. When using the browser the system slows down considerably. I ran the TOP command and I do notice that xorg hits 30 to 40 percent cpu when running the browsers. I have tried these distros on a spare P4 machine and it is even worse. As long as I don't have a several things open at one time I can manage to get around although sluggishly. I also notice that I can't get debian based distros to install in 64bit (crtc6 failure) only in 32bit. Can anyone tell me what is it that I might be doing wrong? I have an integrated Nvidia card and have tried several of the recommended drivers which sometimes result in no boot screen upon reboot. Thanks

• Why does Evolution give me multiple reminders for the same event?

  - by Dylan McCall

  I have a bunch of calendars on my Google Calendar account (school & work, personal, etc.), so I have Evolution subscribed to each one of those calendars. When I get a notification for an upcoming (recurring) event, I actually get many notifications for the same event, all at the same time. For example, just now I got 21 notifications for one event. I am using Gnome Shell, where the message tray displays event notifications in its own way. I get the same behaviour on my other computer, also running Ubuntu 11.10 with Gnome Shell. (And it has happened running Unity where Evolution only shows its dialog window with event reminders, but I'm not sure if it has happened quite as intensely). Does someone know why this is happening, and maybe how to fix it? It would be cool to get slightly less panic-inducing event reminders :)

• Does Ubuntu 12.04 supports for B75 boards?

  - by rail02000

  I want to build a new computer with Intel G840 CPU and Gigabyte B75M-D3H motherboard and install Ubuntu (or Kubuntu) 12.04 64bit on it. However, I'm worried about whether the chip is too new and whether that Linux Kernel now has support for it. According to the article [Phoronix] Intel Core i7 3770K Ivy Bridge Linux Performance Review ,the Linux kernel is ready to work on the chip. Existing Intel Sandy Bridge motherboards/chipsets are compatible with Ivy Bridge processors, but earlier this month Intel launched the new Panther Point chipsets that are already compatible with Linux too: the B75, H77, Z75, Z77, HM75, HM76, UM77, and HM77. But I didn't find further information or cases about running Ubuntu on the chip. So,is it OK to run Ubuntu on the board? Do I need to upgrade the kernel to a newer version (3.4 or 3.5 etc.) to get the system more smoothly? Or should I choose boards with H61 chip? Thank for your response!

• About to graduage from good school without any progamming skills

  - by newprint

  Not sure if it is good place to ask this question, but found this section to be suitable. I am about to graduate from good school (in the US) with Computer Science degree, having good grades and high GPA. I have no freaking clue how to write a good program, how to properly test it... nada, zero. We were never been tough how to write software. Ye, sure the Comp. Architecture class is important, and I can tell you a lot about how MIPS processor works, and I can tell you about Binary Trees and Red-Black Trees and running time of operations in Big Oh, but it has nothing to do with programming in "real" life. For god sake, none of my classmates know how to use STLs or write templated code !!! To be honest, I found that many of my classes to be waste of time. What should I do ? How to step into real life and learn how to program ?

• How to access UbuntOne when it asks for default keyring which has never been set?

  - by obu-tim

  I am trying to set up UbuntuOne on a new computer and after I enter the email and password, it asks for the keyring 'default'. I don't know what it is and I never set it. Makes it difficult to enter so it seems to be a counterproductive security default. I understand that if autologin is set the keyring is called. I tried setting the main user to need a password but if I reboot it doesn't ask for the password so it sort of autoboots still. So How do I set the keyring default password? If I can't set it I can't install UbuntOne

• How to display time in the top panel?

  - by Mörre

  I thought I already had the time up there in the top bar, and it may have been so in previous Ubuntu versions (don't remember, my Ubuntu laptop is just one of three computers I use). Only that I just noticed - me being someone who never wears a watch, has the cellphone turned off 95% of the time and relying on the computer to tell the time - that there is no time being displayed anywhere, and I had expected it in the top bar on the Unity desktop. I searched around but found no obvious solution, but I'm sure someone immediately knows how I can get my time (back?) into the top bar?

• How to achieve 'Activities' in Unity?

  - by Ralf Hersel

  I like the concept of an activities centric desktop and I wonder if this can be achieved in Unity. For me, an activity is a couple of applications that belong to the same subject, like 'photo manipulation', 'software development', 'office work', 'social activities', 'music and video'. I would like to utilize the virtual desktops to arrange applications that belong to the same activity group. Example: Desktop 1 contains all applications that belong to 'office work' Desktop 2 contains all applications that I need for 'software development' Desktop 3 contains all applications that I usually need for 'photo works' Therefore I would like to give names to the virtual desktops that reflect their purpose. And I would like Unity to auto-start the required applications when I start my computer or when I switch to one of the virtual desktops. Is this possible with Unity (or any other desktop)?

• Cannot boot from Ubuntu Live CD on preinstalled Windows 8 laptop

  - by seferov

  I bought a Sony Vaio with Windows 8 yesterday. I want to install Ubuntu, (latest version), alongside Windows. There is an assist button on the laptop to enter the boot option menu, (otherwise, Windows 8 is booted by default. Whenever I choose the, 'boot from CD' option, it says 'No operating system found'. CD is valid since I tried it on another computer and it worked fine. I have tried both versions, 12.04 and 12.10. What is the problem, or how should I install Ubuntu on my laptop?

• Upgraded to Ubuntu 12.04--keyboard & mouse no longer work--system down!

  - by Mackey Morgan

  I upgraded from Ubuntu 11 to 12.04, today, and everything seemed to go smoothly up to, and including the reboot. However, I now find that my mouse and keyboard no longer function, so I cannot login or otherwise use my computer. I have read other posts on this topic, but most of the answers seem to require the use of a keyboard to implement the solution--and I can't use my keyboard! I downloaded a 12.04 LiveCD and tried booting from it, but I have the same issue with that--no keyboard! My systems is a Lenovo with an AMD64 dual processor, and my keyboard and mouse are USB attached and shared with two other Windows PCs via a KVM switch (so I no the keyboard and mouse work!). I would appreciate some hints about how to make this PC usable, again. Thanks!

• Screen sometimes inverts after locking

  - by hackedd

  Sometimes, when I wake up my computer from a screen lock, one of my screens is inverted. It does not always happen (maybe one in ten times) and it is not always the same screen. Re-locking and unlocking the screen a couple of times fixes the colors again. I have a dual monitor setup on an ATI Radeon HD 3450, using two HP screens connected over DVI. I am using the radeon driver, and according to jockey there are no additional drivers available for my system. Any ideas as to why this happens?

• Cannot boot Windows 7 after installing Ubuntu 13.04

  - by whowantsakookie

  So I boot up my computer after installing Ubuntu 13.04. Grub correctly shows me all available boot options and I am able to boot to Ubuntu. However, when I try to boot into Windows 7, grub hangs at a purple screen. I have an HP laptop. It came with all four primary partitions taken up by the Windows bootloader, the actual Windows partition, one called HP_TOOLS, and another for HP Restore. I was able to back up and delete HP_TOOLS and the recovery partition, and change my disk type from Dynamic to Basic (GParted doesn't recognize Dynamic drives). I then booted into a live session of Ubuntu and made two partitions with GParted: one large partition for storage space that I could use between the two operating systems (sda4), and another extended partition (sda3) which contained Ubuntu (sda6) and it's swap space (sda5). It currently looks like this: I'm not sure if the second paragraph is actually relevant, I just want you to know all the variables in the equation. Thank you in advance for helping this poor noob.

• WUBI Install freezes on startup

  Ok, I don't completely know of all the specifications, but installing Ubuntu 12.04.1 on my cousin's old Windows XP computer, an old Compaq from around 2004. After install via Wubi, and going through several unsuccessful install attempts, I finally get the start up screen of Ubuntu, and it freezes once you get to the pretty default wallpaper. Not even a login screen. Just instant freeze! We've left it on for about a day now and its still frozen, any help? (Please reply ASAP, he wont stop bugging me about it)

• Is it viable to become a contract programmer straight out of college?

  - by M G

  I have a Bachelor of Science in Computer Science and four months research experience designing and implementing a research project. I realize this is highly dependent on my skill set - which includes C, C++, Java, Python, and SQL. I feel I have an advantage in two ways: I am young and am not afraid to work overtime. I am willing to take lower pay to gather a client base/experience, and work nights/weekends to get a few projects under my belt. This may be cliche, but I feel that I can learn new technologies quicker than most. At the very least, I am not a slow study. With this being said, is it viable for me to become a contract programmer? Or do I need the 10+ year skill set that most contractors bring to the table?

• Running an Application on a Different Domain

  - by Mark Flory

  Were I am contracting at right now has a new development domain.  Because of IT security rules it is fairly isolated from the domain my computer normally logs into (for e-mail and such).  I do use a VM to log directly into the domain but one of my co-workers found this command to run things on your box but in the other domain.  Pretty cool. For example this runs SQL Server Management Tool for SQL Server 2008: runas /netonly /user:{domain}\{username} "C:\Program Files\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE\ssms.exe" And this runs visual studios: runas /netonly /user:{domain}\{username} "C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe" It does not solve the problem I wanted to solve which would be to be able to assign Users/Groups in Team Explorer.  It instead still uses the domain I am logged into's groups.
