• No WIFI on Ubuntu 12.04 LTS after today software update

  - by Adchara

  I just got new dell inspiron3537 with Ubuntu 12.04 LTS (no windows O/S). It got some wireless (hard block) yesterday. So, this morning, I ran the software update all the security update. After that I can't see "Wireless" in system setting. So, I updated all the software update and looked thru several web site and found "sudo lshw -c network" command. I tried and found the result below. *-network description: Ethernet interface product: RTL8101E/RTL8102E PCI Express Fast Ethernet controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:01:00.0 logical name: eth0 version: 07 serial: 74:86:7a:40:5d:48 size: 100Mbit/s capacity: 100Mbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=full ip=192.168.1.10 latency=0 link=yes multicast=yes port=MII speed=100Mbit/s resources: irq:60 ioport:4000(size=256) memory:c0700000-c0700fff memory:c0400000-c0403fff *-network UNCLAIMED description: Network controller product: QCA9565 / AR9565 Wireless Network Adapter vendor: Qualcomm Atheros physical id: 0 bus info: pci@0000:02:00.0 version: 01 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: latency=0 resources: memory:c0600000-c067ffff memory:9fb00000-9fb0ffff Please suggest what I should do to fix it.

• Acer Aspire one is falling apart on Ubuntu

  - by Narcolapser

  Question: How do I have my netbook detect and install hardware? Info: I have an Acer Aspire One, it came with windows XP and I loaded it with Win7. I decided I wanted to change to Ubuntu so I tried Ubuntu netbook remix, which failed horribly, and so after attempting 3 or so other OS's I ended with Ubuntu Desktop 9.10. Which worked fine for a while, but there were some minor issues so I asked a question about it here and decided to change my OS again. This last weekend I tried mandriva like that guy in my other question suggested, no success. when I had though my netbook lost the ability to use it's touch pad, I didn't think much of it, just thought it must be a driver or something. But When Mandriva failed, and I also while I was at it tried Damn small linux and Debian, which both failed to, I decided to switch back to Ubuntu Desktop(some where in here my keyboard stopped working for one attempt to). But first I gave the netbook remix one more try. it worked this time, with the exception of it didn't have any networking. I thought it was a driver issue again and finished the weekend with ubuntu desktop 9.10 again. But now things get really crazy. it doesn't know it has a wireless card or an ethernet card. It doesn't know my phone is connected trying to provide wireless broadband either. I'm clueless on what could be the problem. And with only a minimal amount of experience with Ubuntu can't navigate the entire interface with only my keyboard(it doesn't detect a USB mouse when I plug it in, it had when I installed it. in fact the network interfaces were working just fine when I live boot ubuntu to installed it). Even so, I don't know where to go or what to do to make it recognize it's hardware. I'm in a dire situation, any help is welcome.

• Apt pin and self hosted apt repo

  - by Hamish Downer

  We have our own apt/deb repository with a handful of packages where we want to control the version. Crucially this includes puppet, which can be sensitive to versions being different.

• Ubuntu 10.04 RGBA(Transparent theme) bug

  - by Nrew

  I tried to follow this tutorial frome ghacks.net. But I end up with a bug. Everytime I try to change the desktop background or the theme. It opens up lots of folders. And then close it back again. So I cannot do anything when I try to change the background or the theme to the default. Here is the tutorial And I can't even shutdown my machine now, please help. EDIT I tried executing these commands in the terminal sudo add-apt-repository ppa:erik-b-andersen/rgba-gtk sudo apt-get update && sudo apt-get upgrade sudo apt-get install gnome-color-chooser gtk2-module-rgba sudo apt-get install murrine-themes And it installed gnome color changer. It works, and the windows became transparent, but I can't change to the default theme and I can't put a background Here's the screenshot, when I try to change something in the preferences: Its just okay if I can't change the theme, but it won't let me change the background either. Or maybe the background is changed but its transparent just like the other windows. You can see that in the taskbar(or whatever its called in Ubuntu). Its full. What can I do to atleast make the background visible.

  - by Surjya Narayana Padhi

  I recently downloaded Ubuntu 10.10 and created an USB drive with that. I started to run the Ubuntu from that USB drive. But I am facing so much problem. I am thinking why its not so much easy like Windows to do all my job in ubuntu. Always I get some error message or to install something. This time I am getting the following errors. I am trying to download and install Aircrack-ng. So used the command sudo apt-get install aircrack-ng. But the installation stops with the following error : update-initramfs: deferring update (trigger activated) cp: cannot stat `/vmlinuz': No such file or directory dpkg: error processing bcmwl-kernel-source (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: initramfs-tools bcmwl-kernel-source E: Sub-process /usr/bin/dpkg returned an error code (1) I don't even have the aptitude command installed till now. Are all these errors because of I am running the ubuntu from USB drive? Is there any simple and easy way to go to Ubuntu Software Center and download all the required essentials at one shot and then Aircrack-ng? I could not find the Aircrack-ng in Ubuntu Software Center Can anybody give me detail steps to solve all my problems above. I am frustrated searching for updates and installations. When something works and something does not work. Can anybody suggest me how I should proceed after installing ubuntu to run on a USB drive. So that I can use the OS like Windows. Like software download,wireless driver, sound, video, documents, C:, D: all things should be there. Please somebody help.

• Ubuntu+Win7--disk error press any key to restart

  - by Siddharth

  Apparently,none of the solutions in any other posts and forums worked for me For some reasons I decided to remove ubuntu from my hard disk drive. My partition table(presently): (/dev/sda1) (fat32) 900 MiB ---(MBR,I suppose) (/dev/sda2) (ntfs) 70 GiB -----(Windows 7) (/dev/sda3) (ntfs) 314.88 GiB --(Personal File storage) (/dev/sda4) (ext4) 80 GiB -----(Ubuntu 13.04) (unallocated) -----1.31 MiB So,after moving(cut-paste) everything(for backup) from the fat32 partition using win7..I booted into Ubuntu and copied the remaining 3 files(hidden in Win7 file explorer) --bootmgr,bootsect.bak,and one more which I do not remember.TERRIBLE MISTAKE After this I again booted into Windows and deleted ext4 partition..formatted it to ntfs..and shut down the pc.Then,I put in a Win7 bootable USB..using command prompt I entered bootrec /fixmbr,and bootrec /fixboot.. Restarting showed me the GRUB..choosing windows 7 showed me "Disk Error. Press any key to restart." I also installed a fresh Win7 installation on the 80 GiB partition expecting a Windows Legacy Bootloader with two win7 options..but did not work. Then..I used a Ubuntu LiveUSB to put it back to the present configuration(above) since all methods to restore the MBR failed.. I copied back the fat32 partitions backup files but couldn't copy those 3 files.Somehow ,they had been recreated and were non-replaceable. I do not want to format the win7 partition for a fresh one. I have used boot-repair..Restore MBR option brings back to "Disk error...." without even going through grub..so I reinstalled grub and I'm able to boot into Ubuntu. grub menu shows the win7 option as "Windows 7 (loader) (on /dev/sda1)". paste.ubuntu.com/5753710 paste.ubuntu.com/5775999

• trying to setup multiple primary partitions on ubuntu linux [migrated]

  - by JohnMerlino

  I currently have ubuntu desktop installed on a harddrive. I want to partition the harddrive so that I can reserve 30 gigs for ubuntu server and 30 gigs for ubuntu desktop. The drive has 300 gigs available. Right now I am booting from dvd drive and installing ubuntu server. I selected "Guided partitioning" and created a 30 gig primary partition of Ext4 journaling filesystem, set "yes, format it" for format partition and set bootable flag to on. I intend to use this 30 gig partition to hold ubuntu server and allow me to boot from it. Now I have two other partitions. They are both set to "logical", one is currently using 285.8 gigs and is using ext4 (when I try to set bootable flag to true, it gives a warning "You are trying to set the bootable flag on a logical partition. The bootable flag is only useful on the primary partitions"). More alarming it says "No existing file system was detected in this partition". Actually, Im thinking that this is the parittion that is supposed to be holding my current Ubuntu Desktop. And of course I want this to be bootable and be a primary partition, so I could dual boot from this and the server partition. Now the third partition is also set to logical and it is being used as swap area. My question is regarding that second partition. Its supposed to be a primary partition thats holding my existing ubuntu desktop edition. How do I switch it to primary and to make sure that its pointing to my existing desktop installation?

• java+netbeans+mysql+ubuntu 64 bits LTS VS C#+MS SQL for fast develop trading system

  - by crunchor

  I am going to build a trading system and use with the broker "Interactive Broker" API. The API supports C++ Socket, Java Socket, DDE, Active X APIs in Windows. The API supports Java Socket API, Posix C++ Socket API in Unix kind like Ubuntu. My trading system has some real time long calculations to do and a lot of maths for backtest. I am using a retail trading program Amibroker which is written in C++ and I run it in windows xp 32 bits, it will take me days to do one serious backtest with my G620 Sandy Bridge CPU and 3GB of ram. So for my trading system, I need to have 1. speed, 2. stability, 3. fast development I have done some research, C++ is fastest but I am not good at it and it takes much longer time to develop. Other than C++, Java in linux has the best speed. I also did some research for database and look like mysql has the best speed. Mysql and PostgreSQL both are very popular open source sql db, which one should I choose? I see MySQL has Workbench now which looks like similar to MS SQL management studio so look like a good start. Netbeans should be the most popular Java IDE now and seem like its GUI design can be as easy as Virtual Studio now. I am not sure if made by Netbeans would affect the speed and if its GUI design is really that good and easy to use. Ubuntu 64 bits LTS has good long term support, good community support, and stable. I will buy a new computer if I can create a good trading system for live trading and backtest. Very likely I will buy a I7 or I5 depends on if I7 can really have better speed for my case. Actually I mainly deal with C# in my jobs and I just knew java but not good at java. What would you guys recommend? Any better solution? This will be a big project and very likely life long project for me so I seriously do research including asking you guys before I start and focus on what I should, thanks!

• ZTE USB Modem AC2736, connection not possible in Ubuntu 12.04.1 LTS

  - by Fredo

  It's a long post but nearly covers all my experiments and changes I did to my NM. Hope the information is complete and if there are still question, more information can be provided. I've a ZTE AC2736 USB Modem (CDMA modem) which worked fine in Ubuntu 10.04 /11.10. I recently switched to 12.04.1 (precise pangolin). after the switch the first issue I faced was to connect to internet using my USB modem (ISP: Reliance Brand: Netconnect). Tried to run the drivers provided by Reliance but they are old and won't support Kernel 2.6.30 above. since the code was not downloaded with ISO image (of 12.04) i couldn't compile the files provided in such driver. lsusb does detect it as Modem with output similar to 19d2:fff1 ZTE CDMA technologies inc. (or similar as i didn't note it down) If it is detected as USB storage it shows 19d2:fff5 (as per few online forums, i may be wrong here). I used the network Manager and configured the modem to dial #777 (default) and the ISP provided username:password combination. It tries to connect to internet (3-4 times automatically)but fails to get online. once I was able to connect in the monring hours and the message was flashed 'registered on CDMA home network'. I was able to run an update. the kernel was updated with 3.0.2 -pae OR something similar (can find out if required). I surfed the net for about 2 hours later before restarting. After the restart, again the Modem was not able to get me online. I kept trying for many times. I tried changing the setting in NM. One evening after dark I was able to connect to network with same message flash 'registered on CDMA home network' (the message was similar, i'm not precise here,sorry). I was able to surf the net for nearly 3 hours before I switched off my Laptop. I'm not able to get online after that day, It's been 3 days now. I'll try the observered theory of late/early hours sometime soon as mentioned below. Laptop configuration : Make: Lenovo Model: B480 Processor: Intel B950 RAM: 4G DDR3 HDD: 500 G Broadcom Wireless/Bluetooth/Ethernet LAN OS: FreeDOS / Ubuntu 12.04 LTS (dualboot) Kernel 3.0.2-pae Obeservation : I'm able to connect to internet in those hours when generally the speed is high (low usage by other network (wireless) users). like in early mornings or late nights. This is strange as connection should not be dependent on bandwidth usage. Any help would be appraciated to fix this issue. before I decide to cahnge the OS or ISP.

• Ubuntu Desktop 12.04 LTS - Using Gnome 2, Metacity, Flux

  - by Robottinosino

  I have a fine-tuned and tested setup I can deploy onto GNOME using gconftool and other scripts. I would like to use these configuration settings on Ubuntu too. I have selected Gnome Classic without effects but I am missing the theme: flux (not fluxbox window manager, just the GTK theme for Gnome, as I used to be able to do in 8.04 when I last considered switching distro). How can I go about installing Flux from a fresh install, step-by-step using the GUI or command line, please?

• MySQL open files limit

  - by Brian

  This question is similar to set open_files_limit, but there was no good answer. I need to increase my table_open_cache, but first I need to increase the open_files_limit. I set the option in /etc/mysql/my.cnf: open-files-limit = 8192 This worked fine in my previous install (Ubuntu 8.04), but now in Ubuntu 10.04, when I start the server up, open_files_limit is reported to be 1710. That seems like a pretty random number for the limit to be clipped to. Anyway, I tried getting around it by adding a line like this in /etc/security/limits.conf: mysql hard nofile 8192 I also tried adding this to the pre-start script in mysql's upstart config (/etc/init/mysql.conf): ulimit -n 8192 Obviously neither of those things worked. So where is the hoop that has been added between Ubuntu 8.04 and 10.04 through which I must jump in order to actually increase the open files limit?

• How To Watch Netflix On Ubuntu with the Netflix Desktop App

  - by Chris Hoffman

  We previously covered watching Netflix on Linux and concluded that using a virtual machine was your best bet. There’s now an even better solution – a “Netflix Desktop” app that allows you to watch Netflix on Linux. This app is actually a package containing a patched version of Wine, the Windows build of Firefox, Microsoft Silverlight, and some tweaks to make it all work together. Previously, Silverlight would not run properly in Wine. Note: While this worked pretty well for us, it’s an unofficial solution that relies on Wine. Netflix doesn’t officially support it.

• Tomboy error while tring to sync with Ubuntu one; Can anyone help?

  - by Michael Chapman

  So I'm sure you've heard the song before, but after trying to sync my notes with Ubuntu One(on 10.10 AMD64) I get "Could not synchronize notes. Check the details below and try again." Of course the problem is that there are no details and trying again doesn't help. So I ran tomboy -debug and compared my error to any thing I could find about similar problems (such as the post here) but found nothing useful. Any way here's my first error, I got this using preferencessynchronizationUbuntu_one [ERROR 21:08:42.271] Synchronization failed with the following exception: String was not recognized as a valid DateTime. at System.DateTime.Parse (System.String s, IFormatProvider provider, DateTimeStyles styles) [0x00000] in <filename unknown>:0 at System.DateTime.Parse (System.String s, IFormatProvider provider) [0x00000] in <filename unknown>:0 at System.DateTime.Parse (System.String s) [0x00000] in <filename unknown>:0 at Tomboy.WebSync.Api.NoteInfo.ParseJson (Hyena.Json.JsonObject jsonObj) [0x00000] in <filename unknown>:0 at Tomboy.WebSync.Api.UserInfo.ParseJsonNoteArray (Hyena.Json.JsonArray jsonArray) [0x00000] in <filename unknown>:0 at Tomboy.WebSync.Api.UserInfo.ParseJsonNotes (System.String jsonString, System.Nullable`1& latestSyncRevision) [0x00000] in <filename unknown>:0 at Tomboy.WebSync.Api.UserInfo.GetNotes (Boolean includeContent, Int32 sinceRevision, System.Nullable`1& latestSyncRevision) [0x00000] in <filename unknown>:0 at Tomboy.WebSync.WebSyncServer.GetNoteUpdatesSince (Int32 revision) [0x00000] in <filename unknown>:0 at Tomboy.Sync.SyncManager.SynchronizationThread () [0x00000] in <filename unknown>:0 The next thing I tried was using preferencessynchronizationtomboy_web with the default 'http://one.ubuntu.com/notes/' and got the same error plus one more.

The only other Thing I have noticed is that under systempreferencesubuntu one services, "Notes" is not listed as a service. I don't know if this is normal or not. Thanks for any help and please let me know if anything is confusing.

• How to Install & Use the Window Maker Desktop Environment on Ubuntu

  - by Chris Hoffman

  Window Maker is a Linux desktop environment designed to emulate NeXTSTEP, which eventually evolved into Mac OS X. With its focus on emulating NeXTSTEP, it eschews the task bars and application menu buttons found in many other lightweight desktop environments. Window Maker is now under active development again after seven years without an official release. A lot has changed on the Linux desktop front since Window Maker was last being actively developed, but Window Maker still provides a unique, minimal environment – for users looking for that sort of thing.

• How to switch users without entering password

  - by torbengb

  I'm a newbie running Ubuntu 9.10. I have two users (wife and me), and each user's screensaver is set to lock so that on wakeup, we get to choose which user's desktop to go to. However, Ubuntu requires a password, so this is pretty tedious. I'd like to switch users without entering any password. I know about this trick that works for the boot login, but it doesn't deal with multiple users. Is it possible to set empty passwords for users in Ubuntu, or skip the password in other ways? (I'm expecting real Linux users to suggest that passwordless users must not get any rights and there be an admin user with a strong password. Yes, you're right. But that's not what this question is about. Thanks.)
