• Sound card not detected in 13.04

  - by Ganessh Kumar R P

  I have a problem with my sound card. I don't have volume up or down option anywhere. In the setting -> Sound I don't have any card detected. But when I run the command sudo aplay -l, I get the following output **** List of PLAYBACK Hardware Devices **** Failed to create secure directory (/home/ganessh/.config/pulse): Permission denied card 0: MID [HDA Intel MID], device 0: STAC92xx Analog [STAC92xx Analog] Subdevices: 0/1 Subdevice #0: subdevice #0 card 1: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: NVidia [HDA NVidia], device 7: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: NVidia [HDA NVidia], device 8: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: NVidia [HDA NVidia], device 9: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 And the command lspci -v | grep -A7 -i "audio" outputs 00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 06) Subsystem: Dell Device 02a2 Flags: bus master, fast devsel, latency 0, IRQ 48 Memory at f0f20000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel 00:1c.0 PCI bridge: Intel Corporation 5 Series/3400 Series Chipset PCI Express Root Port 1 (rev 06) (prog-if 00 [Normal decode]) -- 02:00.1 Audio device: NVIDIA Corporation GF106 High Definition Audio Controller (rev a1) Subsystem: Dell Device 02a2 Flags: bus master, fast devsel, latency 0, IRQ 17 Memory at d3efc000 (32-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel 07:00.0 Network controller: Intel Corporation Ultimate N WiFi Link 5300 So, I assume that the drivers are properly installed but still I don't get any option in the settings or volume control. The same card used to work well back in 2010 versions(04 and 10) Any help is appreciated. Thanks

• How do I create a free server-side database to be accessed via Windows forms and/or browser?

  - by NoCatharsis

  I have no formal education in databasing or programming, but I've learned enough SQL, C++, and C# to at least get started setting up a small database on my company's server. Using MS SQL Server 2008 R2, I have created the database and set up columns with proper data types. However, there seems to be a lot of tweaks and details that are way over my head. Since I would like these data to be accessible to the other 7 or 8 people in my office (preferably via web browser), I'm wondering whether this is the best setup for my situation. The other option I've read about is a LAMPP server, which I assume is the competing free option to Microsoft's Express packages. I know nothing of LAMP servers except from the articles I've read on how to set them up (and I believe I even saw a detailed tutorial somewhere). To summarize, my question is this: Which of these (or any other) server setups would best suit my purposes, keeping in mind that I'm a true novice (but willing to learn), and would like to keep it free until I get more experience?

• Home and End keys in Emacs don't work when run from Tmux

  - by Jan Stolarek

  When I run Emacs from Tmux, the Home and End keys do not work (Home key runs the Search command as if C-s was pressed). The problem started when I added this in my ~/.bashrc file: TERM="xterm" export TERM I've read somewhere that TERM variable should not be set manually but this was the only way I was able to solve problems with colors. Without this setting I got different colors in Emacs when running directly from the terminal and different when running from Tmux. This option caused some of the keys not to work in Emacs when it was run from Tmux, so I added this line to my ~/.tmux.conf: set-window-option -g xterm-keys on This solved problem with all keys except for Home and End. Any ideas how to make these keys work again?

• Configuration Tips for better Performance with ADF Mobile Apps

  - by SRINI INDLA

  Some tips to keep in mind to make sure ADF Mobile application's performance is optimal: 1. Select release mode in deployment profile. This is perhaps the most important thing to remember to ensure best performance for ADF Mobile Apps. Selecting this option causes the deployer to package optimized JVM and minified JS libs with the mobile app there by significantly improving the over all performance of the application. 2. For iOS you do not need to do anything else other than selecting  release mode in deploy profile. However, on Android you have to create a keystore and configure it in JDev --> Tools --> Preferences --> ADF Mobile --> Platforms : Android as shown in the snapshot below 3. Steps for generating the Keystore for Android using keytool :  4. Logging level setting in logging.properties: Make sure the log level is set to SEVERE for both framework logger as well as the application logger as follows oracle.adfmf.framework.level=SEVERE oracle.adfmf.application.level=SEVERE 5. When using SOAP WebServices with WebService Data Control make sure you select the option to copy the WSDL. This will cause the JDev to download the WSDL and all the XSDs referenced by the WSDL from the server at design time and package them with the application during deployment. This way the application does not incur the cost of downloading these resources at run time from the device.

• How to change partitioning - may involve conversion of a partition from primary to extended

  - by george_k

  I am having trouble thinking through how I can achieve my partitioning goals. Now my partitions are: sda1 (winA) (primary) sda2 (winB) (primary) sda3 (/ for ubuntu) (primary) What I want to migrate into is (obviously partition numbers need not be exactly like that) sda1 (winA) (primary) sda2 (winB) (primary) sda3 (/boot) (primary) sda4 - extended which will contain sda5 (/home) sda6 (/ for ubuntu) sda7 (swap) I know I may be asking too much, but what would a way to do it? One way I have thought is Create a new primary partition for /boot and split it from the root partition into the new one. It shouldn't be too hard. Then the disk will have 4 primary partitions. Somehow convert the root ubuntu partition from primary to extended. Split that last partition in 3 extended partitions (root, /home, swap) and split the contents there. I am obviously stuck on the 2nd part. Another way could be (maybe easier): Create an extended partition (or two) Split /home there Somehow move everything except /boot to the extended partition. This way /boot will stay on the primary partition that exists now, and will be shrunk as needed, and everything else will end up to the extended partitions. This may sound better, but I'm not too sure how to do the 3rd part. Some details: The disk is almost empty, so I have space to move things around in it, shrink the ubuntu partition etc. I don't want to touch the windows partitions in any way. Reinstallation is not an option. Also using a different partitioning scheme with fewer partitions is not an option (for example not having a separate /boot) Any ideas?

• How to create direct RS232 (PPP) connection from Windows 7

  - by Jonny Wright

  I'm trying to create a direct connection to a hardware device via RS232 serial connection. Am using a USB to Serial adapter and works fine in WinXP but the option seems to have disappeared in Win7. This is the only connection option available for this piece of hardware so I have no choice. Currently have a netbook with WinXP installed purely for interfacing with this hardware. In XP it was just a matter of creating an "Advanced connection" and then "Directly to another computer" etc, I can find no such options in Win7.

• Laptop is Switching DNS Servers

  - by Steffan Harris

  Ok sometime ago I changed my ip address to a static one because I was bored and I wanted to learn more about static ips. I am running windows xp. My laptop works find on the network that i set up a static ip address, but when i go to another network, the incorrect dns servers are being used. When I enter the option to get a dns server automatically, the internet connection works but only for a short time. After that the dns servers resets to the one i entered manually on a previous network. I did this by going to Network Connection-Right Click Local Area Connection and go to properties-Select TCP/IP - then click the Properties button. At this point i am given the option to Obtain an ip address or obtain and address automatically. My question is how do I resolve this problem of the dns server reseting to the previous one.

• How to change Winamp's default skin to Bento?

  - by TomatoSandwich

  If I install Winamp through automated means (e.g. Using http://ninite.com/), it is automatically installed using the default 'boxy' skin. I can't work out how to interface with this skin as easily as the new 'Bento' skin. In addition, there doesn't seem to be an option to download the Bento skin, or change the skin from Default to Bento without uninstalling and reinstalling it again. Is there a menu option or a downloadable skin that is the default Bento skin? Or do I have to re-install to get this 'new default' skin?

• How to turn off screen (DPMS) together with locking session in KDE?

  - by gertvdijk

  First of all, I'm aware a similar question for GNOME is asked here: "Switch off laptop backlight when locking screen". Objective I would like to turn off my screen on locking the session for power saving reasons. Actual problem Locking the screen on Kubuntu (KDE) inevitably triggers the screensaver as far as I can see. There's no screensaver option other than 'Blank screen' together with its background colour set to black that comes just close to my goal. It blanks the screen, but doesn't turn off the screen. Screen's backlight will still be on and not saving any power. Current workaround A workaround via a script + shortcut key is possible, however, it's just a workaround since it doesn't trigger on all ways to lock the session. Therefore, I think it should be possible to have it done more elegantly, for example by providing this option in KDE's configuration dialog of the screensaver. The workaround I am now using is the following. A script that locks the screen and turns off the screen: #!/bin/bash qdbus org.freedesktop.ScreenSaver /ScreenSaver Lock xset dpms force standby and let it run with a shortcut key via a custom menu entry. It works. Here's why I consider it to be a workaround rather than a solution. It doesn't work for other ways to trigger the locking of the session. My actual question(s) Do I need to touching/patching KDE's source? If not what are my options? If so, could someone point me to where I can get started? what do you think is the recommended place in the GUI for configuration? I'm using Kubuntu 12.04 and willing to upgrade to KDE 4.9 or waiting for the 12.10 release.

• Handout export to word from PowerPoint are too big :(

  - by nickjohn

  EDITED i am using power point lectures. i want to mail merge speaker data into the respective lecture. now thats not possible with ppt as far i know, so i have to convert these lectures to handout by using power point option "publishMS word handouts" and use word mail merger. this is good since it will keep the comments/notes added in slides in handouts aswell. but these exported handouts in word remain actual slides and retain link to original ppt rather than simply get exported as images. so the file size gets verrry big 10mb ppt = 212mb doc=88mb docx Is there any option to convert handouts exported from power point to word as images? i simply cant save them as pngs from powerpoint since that will not include the comments data. Thanks

• Problem with missing JSON functions on PHP 5.2.6 / Plesk 8.4

  - by Drachenviech

  I have a vserver running openSuse 10.3, Apache 2 and Plesk 8.4. I can update/upgrade neither, as it is apparently not recommended to upgrade openSuse 10.3 (and an update to the EOL 10.4 does not seem to make much sense) and Plesk fails to update no matter what version I try (even fails to upgrade to 8.4.1). Still I can live with that somehow, primarily because I don’t have the time to do a fresh remote install on the vserver. What really is a problem is, that though the installed PHP is 5.2.6 it has no zip library and no json functions. The first is probably because PHP was not compiled with --enable-zip. The second is a big mystery though. As I understand it, it always comes with PHP unless its compiled with the --disable-json configure option. This is however not the case. And the json extension module is just not there. I even tried to enable it with extension=json.so with no luck either. the configure options of my PHP are (as shipped with Plesk 8.4) '../configure' '--prefix=/usr' '--datadir=/usr/share/php5' '--mandir=/usr/share/man' '--bindir=/usr/bin' '--with-libdir=lib' '--includedir=/usr/include' '--sysconfdir=/etc/php5/apache2' '--with-config-file-path=/etc/php5/apache2' '--with-config-file-scan-dir=/etc/php5/conf.d' '--enable-libxml' '--enable-session' '--with-mm' '--with-pcre-regex=/usr' '--enable-xml' '--enable-simplexml' '--enable-spl' '--enable-filter' '--disable-debug' '--enable-inline-optimization' '--disable-rpath' '--disable-static' '--enable-shared' '--program-suffix=5' '--with-pic' '--with-gnu-ld' '--with-system-tzdata=/usr/share/zoneinfo' '--with-apxs2=/usr/sbin/apxs2' '--disable-all' '--disable-cli' As I understand it, PECL is not an option with 5.2.6. Or am I mistaken? Even if I was not, the openSuse repository only goes as far as PHP 5.2.4. The openSuse install even came without zypper, which I had to manually install. So is there a way to get ziplib and json running in PHP 5.2.6 without having to recompile the binary?

• iMac boot from linux partition on external drive

  - by user74757

  I have the following "setup:" iMac (no internal drive/dead) --------- (Firewire) ------- [[MAC OS X]] | | | | (USB) | | | | [[MISC STORAGE PARTITION] [MISC STORAGE PARTITION] [EXT2 UBUNTU PARTITION]] I routinely use the firewire drive to boot MAC OS X. However, I would like to boot from the linux partition of the USB drive. This linux partition had linux installed on it from a live cd, and during that process, I told the installer to install GRUB on the usb drive (which happened to be /dev/sdd). My question is, how do I get this disk to show up during the iMac option-boot? Currently, only the firewire MAC OS X option shows up. I have read about rEFIT, but that appears to install it to the Mac OS X disk (would that still work?)... Also mentioned was installing rEFIT to the internal EFI system partition, but I don't know if that is wise.

• xinet vs iptables for port forwarding performance

  - by jamie.mccrindle

  I have a requirement to run a Java based web server on port 80. The options are: Web proxy (apache, nginx etc.) xinet iptables setuid The baseline would be running the app using setuid but I'd prefer not to for security reasons. Apache is too slow and nginx doesn't support keep-alives so new connections are made for every proxied request. xinet is easy to set up but creates a new process for every request which I've seen cause problems in a high performance environment. The last option is port forwarding with iptables but I have no experience of how fast it is. Of course, the ideal solution would be to do this on a dedicated hardware firewall / load balancer but that's not an option at present.

• Dual Boot menu with Ubuntu and Windows 8 not showing up

  - by user180630

  I know a lot of posts have been written, and I had read most of them when I encountered the problem. None of them solved the problem. I have successfully installed Ubuntu 12.04 on top of Windows 8. Now my PC simply boots into Windows 8. If I press 'Esc' at start of BIOS, and then F9,the GRUB shows up and Ubuntu is listed at the top of the several options to boot from. I did run Boot-Repair once I logged into Ubuntu explicitly from GRUB as mentioned above. I did all said by Stormvirux in this link but was still unsuccessful. The debug info is listed here. Something which confuses me is the message which Boot-Repair stated after it did its job. You can now reboot your computer. Please do not forget to make your BIOS boot on sda (8004MB) disk! The boot files of [The OS now in use - Ubuntu 12.04.2 LTS] are far from the start of the disk. Your BIOS may not detect them. You may want to retry after creating a /boot partition (EXT4, 200MB, start of the disk). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot partition:] option of [Boot Repair]. (https://help.ubuntu.com/community/BootPartition) I don't know why it says it is far from the start of the disk as I see it first in the GRUB menu which comes up at startup. One more input, when I try to place the GRUB in sda, Boot-Repair does not progress giving me the following error: GPT detected. Please create a BIOS-Boot partition (>1MB, unformatted filesystem, bios_grub flag). This can be performed via tools such as Gparted. Then try again. Alternatively, you can retry after activating the [Separate /boot/efi partition:] option. I had to select Separate /boot/efi partition: sdb2

• Best way to reformat/recover in Windows when your CD key is no longer valid?

  - by CSarnia

  I have a copy of Windows 7 Professional that I have downloaded from the MSDN e-academy (thanks to my school). Now, the problem is that these license keys are one-use only. If I need to reformat or do a factory reset, what is the best way for me to do so, without invalidating my license and screwing me out of an operating system? Edit: I would also like to know some information on the "restore to factory settings" option in Windows 7 recovery center. Does it do exactly as the name implies and starts you off as if you had just done a fresh install? If I had some kind of nasty trojan or virus, would it be able to survive through the factory reset? The recovery center also has an option for reformatting, though I don't think that it's an actual format - it just backs up your stuff into a Windows.old folder or something like that. Does that require a valid license key?

• Triple (3) Monitors under Linux

  - by widgisoft

  I have a 3 monitor setup (each 1680x1050) via an Nvidia NVS440 (2 GPUs, 2 outputs per GPU totalling 4 outputs); this works fine under Windows XP,7 but caused considerable headaches under Linux (Ubuntu 9.04). I had previously used an XFX 9600GT and the onboard XFX 9300GS to produce the same result but the card was noisy and power hungry and I was hoping that there was some magical switch in the NVS4400 that got rid of this annoying problem - turns out the NVS440 is just 2 cards on one physical PCB :-p (I searched the net high and low for people using this card under Linux but found nothing, if anything the card uses less power and is fan less so I was to benefit from it either way) Anyway, using either set up there were 5 solutions available: Have 3 separate X instances, all un joined Have 3 separate X instances, adjoined by Xinerama Have 2 separate X instances - One using twin-view, both adjoined by Xinerama Have 2 separate X instances - One using twin-view but no Xinerama Have a single Twin-view setup and leave the 3rd screen unplugged :-p The 4rd option, using 2 separate X instances and twinview (but no xinerama) was the best balance in terms of performance and usability but caused 2 really annoying issues You couldn't control (without altering the shortcuts) which screen an application opened onto - and once it was opened you couldn't move it to another screen without opening up terminal and forcing it to move Nvidia's overriding or falsifying of Xinerama breaks and the 2 screens joined by Twin view behave like a single huge screen causing popups to open in the middle of both screens and maximising of windows stretches to the width of the first 2 screens Firefox can only run one instance as the same user so having multiple firefox windows requires at least 2 users The second option "feels" like the right option, but OpenGL is basically disabled and playing any sort of game or even running anything graphical causes a huge performance drop and instability - even trying to run a basic emulator for gba or gens just causes the system to fall over. It works just enough to stare at your desktop and do nothing but as soon as you start doing some work - opening windows, dragging things around - running multiple copies of firefox it just really feels slow. The last open, only going dual screen works perfectly and everything performs as required, full GPU acceleration - two logical screen spaces - perfect, just make it work across GPUs like windows! :-p Anyway, I know RandR was supposed to pick up the slack when it would introduced GPU objects of sorts to allow multiple GPUs to be stitched together to create one huge desktop at a much deeper layer than Xinerama. I was wondering if this has now been fixed (I noticed X server 1.7 is out) and whether anyone has got it running successfully? Again, my requirements are: One huge desktop to drag any window across Maximising of windows to each screen (as XP does) Running fullscreen apps on the primary screen and disabling the mouse from moving onto the others or on all 3 stretched Finally as a side note; I am aware of the Matrox triple (and dual) head splitter but even the price they go for on eBay is more than I can afford atm, my argument: I shouldn't have to buy extra hardware to get something to work on Linux when it's something that's existed in the windows world for a long time (can you tell I don't get on with X :-p); If I had the cash I'd have bought the latest version of this box already (the new version finally supports large resolutions as the displays I have 1680x1050 each).

• Forking a GPL dual licensed software with business owned copyrights

  - by Eric

  After receiving some threats of the copyrights holder of a dual licensed software(GPL2 and commercial) to buy the commercial version for projects in production, I am thinking to make a fork. In a case of GPL2 and commercially dual licensed with business owned copyrights software, is forking the GPL2 version an option? Also, is forking a good way to deal with such cases? Background information The software is a web CMS released under 2 versions a GPL2 free open source edition and a commercial edition including technical support and extra functionality. The problem is that now, basing their argumentation on the "distribution" definition of the GPL2, the company holding the copyrights argue that delivering the software and some extensions to a client is considered as a "distribution". And that such a "distribution" falls under the GPL2 obligation to release the custom made extension code. Custom made extensions are mainly designs, templates and very specific functionality. Basically they give me 3 choices: Buying the commercial licensed edition for projects based on the GPL in production, Deleting all the projects in production based on GPL2 version, Releasing all the extensions as GPL2 code. The first 2 options are nothing realistic for finished projects. The third option could be fine, but as most of the extensions are very specific, cleaning the code to make it usable by other users means lot of works and also I am not sure the clients will appreciate to have their website designs and specific functionality released publicly. The copyrights holding company even contacted some clients directly, giving them the "choice". I know that this is a very corporate interpretation of GPL2, and a such action is nothing close to legal, but as an independent developer, I don't want to take the risk to get involved in some long and tiring legal procedures. PS. This question was first asked on Stack Overflow where it felt out of the scope and closed, after reading the present site FAQ, discussing about software licensing seems fine.

• I need a form to tie MySQL Records together.

  - by John R

  I need a HTML-based form to tie database records together. The user scenario that I envision is somthing like this: A super-user does a search of the database and is delivered a table of records based on that search; each record is numbered with the database-record id. There would also be two text fields next to each record. These text fields would allow: the user to make a reference from one record to another. For example, a user could enter into record id #457 the integer 242 to indicate that there is a correlation with record ID #242. The user would also describe the type of relationship it is. This could be accomplished with a simple integer in the second field that indicates the type of relationship between the two records. When the super-user hits the submit button, all of these relationships are saved in a mySqljoin table. One option is to give me advice on how to implement and code this myself in PHP. However, before I reinvent the wheel, another option is to lead me to a free script that does something similar.

• Traverse tree with results. Maybe type in Java?

  - by Angelo.Hannes

  I need to check a tree's node state. It can either be OK or NOT_OK. But that state is dependent on its children. So for a node to be OK, every of its children needs to be OK. If one or more of its children is NOT_OK the whole node is NOT_OK. To determine the state of a node I need to aggregate some properties of the node. So I thought of two possible implementations. And they are more or less covered in this question: Why is Option/Maybe considered a good idea and checked exceptions are not? Exception I could pass the properties up the recursion path, and throw an exception if something went wrong. Maybe I implement an Maybe type and let it either hold an error or the aggregated properties. Maybe it is more an Either. I tend towards the last option. And I'm thinking of an enum with two objects. Where I can additionally set those aggregated properties. Am I on the right track? I'm not familiar with the new JDK8 functional stuff. But I'm stuck on JDK7 anyway, so please focus on JDK7.

• why doesn't my computer resume after sleeping overnight?

  - by bamdad

  i'm having a weird, weird bug that's been haunting me since 11.10. if i listen to music or watch a video and my computer automatically goes to sleep at night, it won't properly resume in the morning. otherwise, suspend and resume works just fine. what happens is that the wi-fi and bluetooth indicator (that turns from white to orange when suspending) stays orange, the display doesn't turn on, and the only option i have is to hard reset the machine. here's what i've tried so far: installing (and uninstalling and reinstalling) laptop-mode-tools switching the proprietary wireless driver (broadcom-wl) to the open source one (brcmsmac & bcma) and back unloading (and blacklisting) all bluetooth modules (rfcomm, btusb, bnep, bluetooth) and stopping (# stop bluetooth) and disabling (# echo 'manual' /etc/init/bluetooth.override) the bluetooth service creating a custom pm sleep action as suggested here: http://ubuntuforums.org/showthread.php?p=11926504 not watching youtube / any stuff that uses flash before going to sleep (i have flashblock, and i checked $ ps aux | grep flash) because i suspected flash to be the culprit trying out different versions of fglrx (the one from the repos, then installing the latest one from amd's site via generated .deb files, then back to the official ones) none of these worked. i remember back in the days of 10.04, there was a gconf key called network sleep: i thought about disabling that, since re-enabling the wireless card seems to be the problem (according to the indicator led), but the option appears to be missing from gnome 3 (unity-2d, whatever). does anyone have any ideas? thanks, bamdad

• How do I prevent home folder files and folder from showing on the desktop as icons in Linux Mint 15?

  - by N Rahl

  I have a fresh install of Mint 15 with Cinnamon and I can't find an option to hide all icons on the desktop. In settings-Desktop there are only options to show/hide the home folder, trash, etc, but no option to hide the contents of the "Desktop" folder. How do I hide the $HOME folder contents from appearing on the desktop in Linux Mint 15? UPDATE: It actually looks like the icons on the desktop are the contents of the $HOME folder, not $HOME/Desktop. ** Question was edited to reflect the fact that it was the user's home folder icons showing, not just "my computer", "trash", etc.

• I would like to have a publicly accessable linux box hosted elsewhere. Who provides this service?

  - by Eric Wilson

  I would like to have a general purpose linux server available and publicly accessible. I understand that there are no lack of web-hosting companies, but I might want more control over the machine than is typical. I would want the ability to install software, such as an SVN server, and I would like to be able to expose various port numbers, as I may have a variety of extremely low traffic sites that I would want to have available. Obviously, one option is to host such a machine in my home. Is that my only option? Or is what I describe out there, possible as a virtual machine on a larger server?

• What's hot in Oracle Premier Support News for Solaris, Storage and Systems - How to Patch!

  - by user12244613

  Struggling with locating patches for Sun products? Can't find your Oracle System Drivers? This question has been raised many times by customers and was the source of a short video in the Oracle System Support Newsletter in February 2012. The transition between SunSolve and My Oracle Support is to change how you think about the type of patch your looking for. For example, in SunSolve you might have typed e1000g if looking for an Enternet Driver.. but entering e1000g will not find anything in My Oracle Support - Patches and Update Menu. As you need to use the Product (Advanced) search which is driven of the Product Name, therefore you need to type "Ethernet" and select the ethernet product you are looking for to locate the patches for this product. Just to recap that video: If you are looking for the e1000g Ethernet Driver - You need to use Advance Search and search for Enternet 1. Log into My Oracle Support - Select Patches and Updates - Select Product or Family (Advanced Search). 2. In the product line enter: Ethernet and select the product name from the menu. 3. Check remove supersede patches - that ensure you only get relevant current patches in the results. 4. Select Search and the results are displayed. Now you have more options to include the platform (Solaris,Linux etc.) if want to further narrow the search. Need more information? Log into My Oracle Support and what a short 90sec video I put together. View the 7 minute Video using Firefox/chrome – It shows searching for individual patches, Solaris, Firmware etc. If you are not receiving the Oracle System Support Newsletter: Option (a) Within My Oracle Support, make document id: 1363390.1 a favourite and revisit it on the 2nd of each month for the latest content. Option (b) By default the Newsletter  is sent to all customers who have logged a Service Request on an Oracle Systems Hardware Product during the last 12months, unless you have opted out to receiving Oracle Communications on your profile on http://oracle.com
