• Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E

  - by Sebastian Bugiu

  I had Ubuntu 11.10 and in the last few weeks I experienced an obscure problem: after I had the computer running for a few days I could no longer connect to google.com or anything related to google. All sites worked with all browsers (Firefox, chrome, opera) except google. It remained in the connecting phase for a few minutes and either timed out or finally connected with this huge delay. Even if I entered other sites such as this one, if it had anything to do with google such adsense or gstatic or whatever with g in it, that site took a long time to load waiting in connecting to gstatic.com . Anything google related took minutes to work, but everything else worked instantly! I tried rebooting or using other machine(with windows on it) and this worked, so it's not network related. But after a few days it started not working again... So I upgraded to the Precise Pangolin hoping this behavior would go away. It didn't! After a few days I get the same behavior as in 11.10. What am I supposed to do? Reboot every other day? I didn't have this problem with neither 10.10 or 11.04. I found the Realtek RTL8168/8111E issue with the r8169 driver but this is not exactly the same card so probably trying r8168 won't help. Ethernet controller: Realtek Semiconductor Co., Ltd.

• Microphone on a Dell Vostro 3360

  - by Pilb

  After upgrading my vostro 3360 on Ubuntu 12.04, I saw that drivers were not available for this version (notably for network). So I decided to install 11.10 but the mic still doesn't work (notably on Skype, Gtalk etc.) I join the model of the audio device and the drivers which were installed before I upgraded to ubuntu 12.04 (I succeeded only in installing the network one) Can you help me to find the solution to this problem with my microphone? Thanks , Pilb. Message in French : Bonjour, Après que je me sois rendu compte d'une anomalie dans la gestion du micro (sous Gtalk), j'ai essayé différentes solutions sans succès (1 2 et 3) Mon ordinateur dell vostro 3360 m'a été livré sous ubuntu 11.10, j'ai voulu le mettre sous 12.04 mais les drivers n'étaient pas compatibles. Je suis donc revenu sur Oneiric mais sans les drivers installés par Dell en usine. néanmoins, j'ai pris soin de noter leurs références (sans toutefois savoir si le micro fonctionne avec ces pilotes, mais cela me semble possible).

• Ubuntu 12.04.1 Radeon 9550 stuck with 640x480, works in Geexbox

  - by Betty

  I am a complete new user trying to set up Ubuntu on an old desktop. It has an AGP Radeon 9550 graphics card. I am running Ubuntu from a USB drive with persistence as the PC currently has no hard drive I seem to be stuck in 640*480 mode. The desktop itself is larger, but the monitor display is stuck on 640*480. In SettingsDisplays, only the 640*480 option is available. What I have found out so far: The proprietary ati drivers no longer support my card. If 3D isn't an issue (it's not) the open source driver should be fine. This should be installed by default so in theory I am using it already xserver-xconf/pci/*.ids doesn't show any entries for the card's PCI id. hardware additional drivers show no proprietary drivers I tried the booting into the current version of Geexbox from a USB stick and this set the resolution correctly by default so I know it can be done, but I know no idea how. How can I tell what driver the card is using, and how can I get the higher resolutions back?

• jackd fails to start

  - by wickedchicken

  I'm trying to have a setup where JACK interfaces directly to ALSA and pulseaudio communicates to JACK. This setup worked OK (I had to manually start things a few times) but as I understood the Ubuntu daemon setup and perfected things jackd stopped working completely. I'm running 10.10. If I run something through ALSA I get sound no problem. However, when I run jack with realtime: /usr/bin/jackd -v -R -ch -Z -t2000 -d alsa -P I get the following error: jackd watchdog: timeout - killing jackd Conversely, if I run without realtime: /usr/bin/jackd -v -r -ch -Z -t2000 -d alsa -P I get: ALSA: poll time out, polled for 32032138 usecs DRIVER NT: could not run driver cycle Jack was working just fine before I made these changes; while I don't have an exact copy of my original configuration I recall running the bare minimum of options worked fine. I've seen some articles saying the problem is with ALSA capture. In fact, I tried enabling capture in alsamixer once and everything worked! On reboot that success was not repeated and I haven't been able to get jack working since. That shouldn't matter because specifying -P should obviate any capture issues. Short summary: I can't get jackd to work under any circumstances (unless I specify -d dummy). Sound works with other programs with ALSA, but when I run JACK the daemon opens the card but times out and dies. JACK worked fine before but I can't figure out what changed (or where to even look). I should mention I am running with CPU speed throttling on, but I'm using HPET to mitigate this (and I've run jack with no issue before). Thanks!

• NTFS and NTFS-3G

  - by MestreLion

  I have a netbook with Ubuntu Netbook 10.04 and a desktop with Mint 10 (~ Ubuntu Desktop 10.10) Both of them have read/write NTFS partitions mounted via /etc/fstab. And it works fine. Ive read on net, google, forums, and several posts here, that NTFS-3G is the driver that allows you to have full access to an NTFS partition, that it is new, great, powerful, yada-yada. But... my entries use plain ntfs, no mention of -3g, and they still work perfectly as read and write. Am I already using ntfs-3g? Does 10.04 onwards use it "under the hood"? How can i check that in my system? Should my /etc/fstab entries should use "ntfs-3g" as the fs? Why some posts refer to mount ntfs, while others say mount ntfs-3g ? Im really confused about where should I use fs-type names (ntfs) or driver names (ntfs-3g?). Or is it irrelevant now, and ntfs is always an "alias" or something for ntfs-3g nowadays? Ive read some posts her, from Oct-10 and Nov-10 e that "announce" that ntfs-3g "finally arrived"... thats way post-Lucid 10.04. Could someone please undo this mess in my head, and explain the relation between ntfs and ntfs-3g, what is the current status (10.04 and 10.10), where should i use each, etc (regarding mount, fstab, etc)? Sorry for the long, confusing, redudant text... im really getting sleepy

• Java-JDBC-MySQL Error

  - by LeonardPeris

  I'm trying to get my java program to talk to a MySQL DB. So i did some reading and downloaded MySQL Connector/J. I've extracted it into my home directory ~. Here are the contents. user@hamster:~$ ls LoadDriver.class LoadDriver.java mysql-connector-java-5.1.18-bin.jar The contents of LoadDriver.java are user@hamster:~$ cat LoadDriver.java import java.sql.Connection; import java.sql.DriverManager; import java.sql.SQLException; // Notice, do not import com.mysql.jdbc.* // or you will have problems! public class LoadDriver { public static void main(String[] args) { try { // The newInstance() call is a work around for some // broken Java implementations Class.forName("com.mysql.jdbc.Driver").newInstance(); } catch (Exception ex) { System.out.println(ex); } } } The contents are the same from http://dev.mysql.com/doc/refman/5.1/en/connector-j-usagenotes-basic.html#connector-j-usagenotes-connect-drivermanager with the only change that the Exception is being printed to console in the catch block. I compile it as follows leonard@hamster:~$ javac LoadDriver.java When I try to execute it, the following is the ouput. leonard@hamster:~$ java LoadDriver java.lang.ClassNotFoundException: com.mysql.jdbc.Driver This output is consistent with the executing command, but when trying to run it with the prescribed CLASSPATH method I run into the following issue. leonard@hamster:~$ java -cp /home/leonard/mysql-connector-java-5.1.18-bin.jar LoadDriver Exception in thread "main" java.lang.NoClassDefFoundError: LoadDriver Caused by: java.lang.ClassNotFoundException: LoadDriver at java.net.URLClassLoader$1.run(URLClassLoader.java:217) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:205) at java.lang.ClassLoader.loadClass(ClassLoader.java:321) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294) at java.lang.ClassLoader.loadClass(ClassLoader.java:266) Could not find the main class: LoadDriver.

• Ubuntu 14.04: After login, top- and sidepanel don't load and system settings don't open

  - by Löwe Simon

  I have Ubuntu 14.04 on a Medion Erazer with the Nvidia GTX570M card. At first, while I had not installed the last nvidia driver, each time I would try to suspend my pc it would freeze frame on the login. Once I managed to install the nvidia drivers, everything seemed to work up until I noticed that suddenly the system settings would not open anymore. I then rebooted my pc, but when I logged in I just end up with my cursor but no top panel or side pannel. Thankfully, I had installed the gnome desktops which works, except for the fact the system settings do not open also in the gnome desktop. I have tried following: Problems after upgrading to 14.04 (only background and pointer after login) except for reinstalling nvidia, since then I would be back at square one with suspend not working. When I try to launch system settings through the terminal, I get: simon@simon-X681X:~$ unity-control-center libGL error: No matching fbConfigs or visuals found libGL error: failed to load driver: swrast (unity-control-center:2806): Gdk-ERROR **: The program 'unity-control-center' received an X Window System error. This probably reflects a bug in the program. The error was 'BadLength (poly request too large or internal Xlib length erro'. (Details: serial 229 error_code 16 request_code 155 (GLX) minor_code 1) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) Trace/breakpoint trap (core dumped) I know the 2 problems seem unrelated, but since they occured together, I am wondering if that is really the case. Your help is much appreciated, Simon

• Ubuntu 11.10 is falling back to Unity 2D. How to get back to Unity 3D?

  - by marcioAlmada

  It happened some minutes ago when I plugged my secondary monitor and my graphical interface simply crashed. So I had to restart my session. Since the crash Ubuntu insists to use Unity2D fall back instead of the default one. I used to plug the secondary monitor everyday when at home and nothing bad happened before. This 2D version of the GUI is ugly and has a lot of problems. How can I go back to Unity 3D GUI? update It seems somehow I lost my opengl support (driver issues). $ glxinfo name of display: :0.0 Xlib: extension "GLX" missing on display ":0.0".

• AIA - Server Topologien und Deployment

  - by Hans Viehmann

  Es gibt ein neues White Paper, in dem die verschiedenen Varianten von AIA Topologien ausführlich beschrieben sind. Die unterschiedlichen Möglichkeiten ergeben sich vor allem aus dem Betrieb mehrerer AIA Instanzen parallel (z.B. Aufteilung in Dev/Test/Prod, Aufteilung zur Lastverteilung, Zuordnung zu unterschiedlichen Geografien, ...). Weitere Variationsmöglichkeiten bietet die Verteilung der unterschiedlichen Bestandteile des DB-Schemas (AIA Metadaten, Cross-Referencing Daten, AIA Lifecycle Repository, JMS Schema, etc.). Und schließlich können auch verschiedene Topologien der SOA Laufzeitumgebung, wie beispielsweise SOA Cluster, unterstützt werden. Diese Varianten mit ihren typischen Einsatzfeldern werden in dem Dokument ebenso beschrieben, wie deren Umsetzung mit Hilfe des Installers.In einem zweiten Teil befasst sich das White Paper mit dem Deployment der AIA Artefakte in diese Topologien, und zwar insbesondere mit dem Tool-Support durch die "Project Lifecycle Workbench" und dem "AIA Installation Driver". Erstere ist eine neue Komponente in AIA 11gR1, die in der Lage ist, am Ende des Entwicklungszyklus Deployment Pläne zu generieren, während der ebenfalls neue "AIA Installation Driver" dann die Artefakte dann in die Zielumgebung überträgt.Das White Paper ist noch nicht auf oracle.com verfügbar und ist leider so umfangreich, dass es nicht auf auf blogs.oracle.com hochgeladen werden kann. Bei Interesse verschicke ich es aber gern per Mail.

• Trying to use HUAWEI E173 on Ubuntu 12.04

  - by Scott Warren

  I have a HUAWEI E173 usb stick to access the internet. It works normally on windows but I need to use it on my Ubuntu system. I plug it in, and after 25-20 seconds the status light turns green and blinks twice every 3 seconds. I see no changes in my system whatsoever, nothing gets installed, I don't get prompted for my PIN. I tried to create a connection using edit connections. I entered the following parameters: Turkey, Turkcell, My Plan is not listed, Internet. Nothing happens. I tried the lsusb command and got the following: tosh2000@tosh:~$ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 002: ID 058f:a001 Alcor Micro Corp.

• "Oracle", "Sybase", "SQL Server" vs just "SQL/JDBC" in the CV

  - by bobah

  How would you define a testable measure of the expertise that, if you're honest with yourself, lets you write in your CV words "Oracle", "Sybase", or "SQL Server" and not just "Relational Databases, SQL, JDBC" in your software developer's CV? What every XXX-developer (XXX - a vendor name) should know? The question is similar to http://stackoverflow.com/questions/2119859/questions-every-good-database-sql-developer-should-be-able-to-answer but is vendor-specific. Below is a start of the list as an example, demonstrate what kind of answers I am hoping to get. If you are expert in X then you know that Y (X - Y below): Sybase/SQL Server - they are very similar, Sybase is much more expensive Sybase/SQL Server - for Java you can use either native Sybase/JSQLDB driver or jTDS that is using TDS protocol and can connect to SQL Server as well, TDS traffic can be dumped and analyzed with hexdump command Sybase/SQL Server - for C++ you can use FreeTDS to connect to any, for Perl - same Sybase/SQL Server - a query can return multiple result sets and return codes, all need to be processes otherwise errors can happen Sybase/SQL Server - sp_help, sp_helptext Sybase/SQL Server - your tables/views/procedures are under DBName/dbo/... Sybase - for C++ on Linux you can use Sybase client API to connect (at least until recently) SQL Server - JDBC driver has a configurable transparent failover capability Oracle - for C++ Linux one can use OTLv4 that is a very powerful yet lightweight wrapper around Oracle client API Oracle compilation (contributors: ammoQ) PLSQL Java Stored Procedures '' is null Hierarchical Query Analytic Functions Oracle Text

• Unity install removed window borders, and display drivers.

  - by Vivek Sharma

  I installed unity, used for a while. Then i installed gnome-shell, used it for a while. Now decided to switch back to standard. Gnome is not working the way it use to be. I am using T61 with nvidia-latest drivers. Following issues... Window borders are not showing. Installed compiz settings, and re-check window decorations option. I had to re-install nvidia driver, as when I tried to apply normal visual effects, it said no display driver found. Gnome panel is not coming, and mouse pointer is a "cross" than a "arrow". I then opened a terminal and enter gnome-panel. Panel came and window borders came back. Nothing is showing on desktop, and the right click is also not populating the menu. When i loging, an error message saying, docky did not start and it requires compiz to work. After starting gnome-panel from terminal, i went to systempreferencesAppearance. And selected normal visual effects. It activated, i selected keep the settings. Now when i restart or re-login, everything is gone. I have to run gnome-panel manually, and then re-enable visual setting. Ofcourse i can add gnome-panel in startup applications, but i want to know what has installing unity/gnome-shell has done, that these setting are messed up. I manually removed mutter, as Appearance application was showing mutter installed, cant enable effects. What shall i do to get back a standard gnome-desktop back.

• How to switch sound-drivers, and to which? [AMD] Hudson Azalia Controller

  - by Anders Martini

  System settings/sound does not open, freezes and I have to force close. Speaker symbol with volume control does not open scroll-down menu, and there is no sounds. Many people have problems with Hudson Azalia in Ubuntu, but I found no working solution. I don't really understand much of this, but here are some more details: aplay -l : **** List of PLAYBACK Hardware Devices **** (after running this one, it starts some kind of process that doesn't get any results, and doesn't stop, terminal has to be shut down) lspci -vnn | grep -iA5 audio: 00:01.1 Audio device [0403]: Advanced Micro Devices [AMD] nee ATI Device [1002:9902] Subsystem: Hewlett-Packard Company Device [103c:184c] Flags: bus master, fast devsel, latency 0, IRQ 53 Memory at f0444000 (32-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel -- 00:14.2 Audio device [0403]: Advanced Micro Devices [AMD] Hudson Azalia Controller [1022:780d] (rev 01) Subsystem: Hewlett-Packard Company Device [103c:184c] Flags: bus master, slow devsel, latency 32, IRQ 54 Memory at f0440000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel It seems to me that I'm currently running hda Intel drivers on my AMD Hudson Azalia soundcard.

• How do I solve VirtualBox error 0x80004005?

  - by maria

  Hi I was trying to run Windows XP under Virtual Box (host system Ubuntu 10.04) and I've got an error message saying: Kernel driver not installed (rc=-1908) The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Re-setup the kernel module by executing '/etc/init.d/vboxdrv setup' as root. Users of Ubuntu, Fedora or Mandriva should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary. This is terminal output: maria@maria-laptop:~$ sudo /etc/init.d/vboxdrv setup * Stopping VirtualBox kernel modules * done. * Uninstalling old VirtualBox DKMS kernel modules * done. * Trying to register the VirtualBox kernel modules using DKMS * Failed, trying without DKMS * Recompiling VirtualBox kernel modules * done. * Starting VirtualBox kernel modules * done. After that I can run XP on Virtual Box, but when I try to log into user's account, I have the message that I have to register XP (I haven't done it yet, as each time I was cliking on pop-up window suggesting registration, nothing was happening). I click that I want to register it now and appears the message about error 0x80004005, which prevents Windows to check the license for that computer (the message is in Polish, so I don't post it here...). I forgot to install DKMS first, but I've done it after. What should I do to run virtual machine? It was using it already, the problem occured only today. Thanks for any suggestion

• How to re-configure graphics from Intel integrated to Intel / ATI switchable?

  - by Bucic

  There are lots of 'how to get switchable graphics to work' guides but I found none on how to configure a system for switchable graphics operation on Ubuntu from the ground up, nor explaining the current driver situation for particular computer models (integrated+discrete combinations). Example: https://help.ubuntu.com/community/HybridGraphics My system being mature and on Intel integrated card also makes things complicated. System information: Ubuntu 12.04 amd64, installed clean with system configured to use only the integrated Intel card Lenovo Thinkpad T500 Intel GMA 4500MHD / ATI Mobility Radeon HD 3650 Current situation: Mature and up-to-date system with no configuration changes to what's given above. I've made a backup image of the system (Clonezilla) so regardless of what's written below let's assume it's our starting point. If something in What I have already tried is not clear you may as well diregard it. What I have already tried: Configuring BIOS to switchable graphics and: Installing Additional Hardware drivers - returned an error. Installing proprietary amd-driver-installer-12.6-legacy-x86.x86_64.run automatically - system starts to 'low-graphics mode'. Tried fixing as per https://help.ubuntu.com/community/BinaryDriverHowto/ATI#Manually_installing_Catalyst_12.6.2C_special_case_for_Intel.2BAC8-ATI_hybrid_graphics Got lost, gave up. Please note that while configuring BIOS for integrated graphics only is pretty straightforward, configuring for switchable graphics is not.

• Cedarview drivers boot to a blank screen

  I'm following the tutorial following tutorial to get my Intel D2700DC motherboard's graphics working: http://daily.siebler.eu/2012/06/ubuntu-12-04-driver-for-intel-cedarview-atom-n2000-und-d2000-serie/ When I boot I'm getting a blank screen. I followed the tutorial and read all the comments. I've also tried: Install gdm and use this instead of lightdm (ubuntu default) sudo apt-get install gdm Remove previous pae kernel: http://www.liberiangeek.net/2011/11/remove-old-kernels-in-ubuntu-11-10-oneiric-ocelot/ Reboot before adding cedarview packages. Have tried with and without the "video=LVDS-1:d" to GRUB_CMDLINE_LINUX_DEFAULT variable in /etc/default/grub I still get a blank screen. I am plugged into a HD screen through the HDMI and have tried the DVI connector also. I can see the grub menu, then a little of the loading and then 'No signal'.

• Trying to install Canon iP7250 printer

  - by Chris Burmajster

  I'm trying to install my Canon iP7250 printer on a fresh install of 13:10 64bit. Last time I installed it successfully via http://handytutorial.com/install-canon-printer-driver-for-ubuntu-13-04-12-10-12-04 which entailed adding a repository via the terminal and then updating it. I then opened Synaptic and searched for my printer model and Synaptic then installed everything. This time round I added the repositories but the update failed with the following error: Failed to fetch http://ppa.launchpad.net/michael-gru...amd64/Packages 404 Not Found Failed to fetch http://ppa.launchpad.net/michael-gru...-i386/Packages 404 Not Found Some index files failed to download. They have been ignored, or old ones used instead. An internet search failed to find another way of installing this printer so I'm stuck. My laptop also runs 64 bit 13:10 and the printer works, as I installed it months ago. Is there any way I can take something off that to use on this new machine? Thank you all in advance P.S. I have just found and downloaded the official Canon driver from the Canon website and extracted it, but I don't know how to install it.

• How to install compat-drivers or compat-wireless

  - by Sasho

  Could someone please explain me in detail how to install some of this drivers. I am running Ubuntu 12.04.2 and have the infamous (as I see everywhere in the net) problem with Atheros AR9462 wifi card. I tried everything to fix it and compat drivers are the only solution that I haven't tried. I tried to install some random package from kernel.org site and it couldn't make the driver (it threw some error). Then I updated the kernel to 3.10-rc7 and downloaded the last release of compat drivers and again the same problem occured. I reinstalled Ubuntu 12.04.2 and now I am using the 3.5 kernel because I don't know if rc7 is stable version. So my question is which compat wireless or compat drivers to download for this kernel and what is the process of installing. I tried with some command from the repository and it returned that it's not found. PS I am new to Ubuntu and Linux in general so explaining at length the install process and which driver I should install would be appreciated.
