• How can I get my ATI / AMD drivers to work with any kernel above 3.2.0.x?

  - by TorakTu

  How can I get my ATI / AMD drivers to work with any kernel above 3.2.0.x ? WHAT DID WORK Installed original AMD64 version of Ubuntu 12.04 ISO image. Burned DVD and installed which shown kernel 3.2.0-23 to begin with. Got 5.1 surround sound working. Got ATI ( Now its AMD ) video drivers installed for my Radeon HD R6870 Video card from AMD's website. fglrxinfo came up and reported as normal. THE PROBLEM Kernel 3.2.0.x kept locking up so I tried higher kernel versions. But ATI / AMD Drivers do not install on any kernel Above 3.2.0.x WHAT I HAVE TRIED I have gone over this tutorial many times ( https://help.ubuntu.com/community/BinaryDriverHowto/ATI ) and it doesn't work on ANY kernel except 3.2.0.x. The problems I am having here are that the ATI / AMD drivers working for the 12.04 Precise with kernel 3.2.0-23 and 24, But the computer kept locking up. Although all my games would work, the lock ups were random and were constant. So I looked all over the web for 3 days trying to find an answer and the lock up issue was said to just update the kernel. So I did. Have tried many kernels. All of them .. no lock ups. BUT the Restricted AMD drivers from the AMD website will not install. And none of the OpenSource AMD drivers have EVER installed no matter what Kernel or version I tried. EXAMPLE OUTPUT OF 3D TYPE OF ERRORS Javax.media.opengl.GLException: glXGetConfig failed: error code GLX_NO_EXTENSION at com.sun.opengl.impl.x11.X11GLDrawableFactory.glXGetConfig(X11GLDrawableFactory.java:651) at com.sun.opengl.impl.x11.X11GLDrawableFactory.xvi2GLCapabilities(X11GLDrawableFactory.java:350) at com.sun.opengl.impl.x11.X11GLDrawableFactory.chooseGraphicsConfiguration(X11GLDrawableFactory.java:174) at javax.media.opengl.GLCanvas.chooseGraphicsConfiguration(GLCanvas.java:520) at javax.media.opengl.GLCanvas.<init>(GLCanvas.java:131) at haven.HavenPanel.<init>(HavenPanel.java:68) at haven.HavenPanel.<init>(HavenPanel.java:78) at haven.MainFrame.<init>(MainFrame.java:182) at haven.MainFrame.main2(MainFrame.java:306) at haven.MainFrame.access$100(MainFrame.java:34) at haven.MainFrame$7.run(MainFrame.java:360) at java.lang.Thread.run(Thread.java:722) And of course this is what fglrxinfo shows : X Error of failed request: BadRequest (invalid request code or no such operation) Major opcode of failed request: 139 (ATIFGLEXTENSION) Minor opcode of failed request: 66 () Serial number of failed request: 13 Current serial number in output stream: 13 EDIT : I forgot to mention that I DID look at this post over the last few days and it did not help.

• Systemd can't start script?

  - by TokyoMEWS

  I have a BASH-script I want to run on start up. My system is running systemd so I created a .service file with whith what I think is the neccessary information: [Unit] Description=My Script After=network.target [Service] ExecStart=/home/myscript.sh [Install] WantedBy=multi-user.target I used systemctl enable to 'register' it an rebooted. On boot I was told my script would be executed, but I could neither see any of the messages ECHO should display on screen nor did it write something to a file, according to what I had written in the script. Additionally, It does not start the application it's supposed to start. Systemctl status tells me that the script has run and exited successfully. Still, the script has no effect. If I run the script from a shell it works perfectly fine. Do any of you know what could be my problem?

• Nested Entities and calculation on leaf entity property - SQL or NoSQL approach

  - by Chandu

  I am working on a hobby project called Menu/Recipe Management. This is how my entities and their relations look like. A Nutrient has properties Code and Value An Ingredient has a collection of Nutrients A Recipe has a Collection of Ingredients and occasionally can have a collection of other recipes A Meal has a Collection of Recipes and Ingredients A Menu has a Collection of Meals The relations can be depicted as In one of the pages, for a selected menu I need to display the effective nutrients information calculated based on its constituents (Meals, Recipes, Ingredients and the corresponding nutrients). As of now am using SQL Server to store the data and I am navigating the chain from my C# code, starting from each meal of the menu and then aggregating the nutrient values. I think this is not an efficient way as this calculation is being done every time the page is requested and the constituents change occasionally. I was thinking about a having a background service that maintains a table called MenuNutrients ({MenuId, NutrientId, Value}) and will populate/update this table with the effective nutrients when any of the component (Meal, Recipe, Ingredient) changes. I feel that a GraphDB would be a good fit for this requirement, but my exposure to NoSQL is limited. I want to know what are the alternative solutions/approaches to this requirement of displaying the nutrients of a given menu. Hope my description of the scenario is clear.

• Defining a function that is both a generator and recursive [on hold]

  - by user96454

  I am new to python, so this code might not necessarily be clean, it's just for learning purposes. I had the idea of writing this function that would display the tree down the specified path. Then, i added the global variable number_of_py to count how many python files were in that tree. That worked as well. Finally, i decided to turn the whole thing into a generator, but the recursion breaks. My understanding of generators is that once next() is called python just executes the body of the function and "yields" a value until we hit the end of the body. Can someone explain why this doesn't work? Thanks. import os from sys import argv script, path = argv number_of_py = 0 lines_of_code = 0 def list_files(directory, key=''): global number_of_py files = os.listdir(directory) for f in files: real_path = os.path.join(directory, f) if os.path.isdir(real_path): list_files(real_path, key=key+' ') else: if real_path.split('.')[-1] == 'py': number_of_py += 1 with open(real_path) as g: yield len(g.read()) print key+real_path for i in list_files(argv[1]): lines_of_code += i print 'total number of lines of code: %d' % lines_of_code print 'total number of py files: %d' % number_of_py

• Which Bliki (Blog+Wiki) solution can you recommend?

  - by asmaier

  I'm searching for a good Bliki solution, meaning a combination of blog and wiki that I can install on my own web space. I would like to be able to write articles in the wiki style much like with media wiki. So I want to use a wiki markup language, have a revision history, comments, internal links to other pages (maybe in other languages) and be able to collaboratively edit the articles. On the other side I would like to have a blog-like view on my articles, showing new articles (and changes to existing articles) in a time ordered fashion. It would be nice if it would be possible to search through the articles and also tag the articles, so one could generate a tag cloud for the articles. A nice feature would also be to be able to order the articles according to views or even a voting system for the articles. Good would also be a permission system to keep certain articles private, showing them only to people logged in to the platform. Apart from these nice to have features an absolute must have feature for the Bliki platform I'm searching is the possibility to handle math equations (written in LaTeX syntax) and display them either as pictures like media wiki or even better using Mathjax. At the moment I'm using a web service called wikiDot which offers some of the mentioned features, however the free version shows to much advertisements, the blog feature is not mature, the design is quite ugly and loading of the page is often slow. So I want to install a Bliki solution on my own webspace. Can you recommend any solution for that?

• How do I stop color changes when quitting vi from a terminal emulator?

  - by Michael Warhol

  I have a problem with colors when using vi under Ubuntu 12.04. I'm connecting to my Ubuntu server from a PC, using PowerTerm terminal emulation software. I have PowerTerm set up to display black text on a grey background. When I connect to the Ubuntu box, the screen is fine. When I open a file with vi, the screen is fine. The text is black on a gray background, which is normal for my PowerTerm setup. However, if the file is less than a full screen long, the remainder of the screen is a black background. When I quit vi, the entire background turns black, and the text becomes white. I have to do a Terminal Reset to restore my normal text and background colors. What I want is for there to be no change at all when I use vi. The text should be black and the background grey. I have another server loaded with RedHat 9, and that acts normally; colors don’t change when using vi. Here is my .vimrc file: set compatible syntax off let g:loaded_matchparen=1 set nocp set noincsearch set nohlsearch set noshowmatch set bg=dark I've tried set bg=dark and set bg=light. It makes no difference. Is there some other set command that would clear this up for me, or some TERM setting (my TERM is set to linux)?

• Can't start webcam for google video services

  - by wisemonkey

  I've got Ubuntu 11.10 64 bit and have installed the google video chat plugin. However webcam doesn't seem to work (black screen -- no video at all). For cheese it works but shows really bad (black and white kinda) image. Following some link I installed guvcview if I start it then image looks neat. Any suggestions on how can it be fixed? If it helps I've tried the solution: $ sudo mv /opt/google/talkplugin/GoogleTalkPlugin /opt/google/talkplugin/GoogleTalkPlugin.old $ sudo gedit /opt/google/talkplugin/GoogleTalkPlugin and putting following lines in: #!/bin/sh LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so /opt/google/talkplugin/GoogleTalkPlugin.old OR #!/bin/sh LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4l/v4l1compat.so /opt/google/talkplugin/GoogleTalkPlugin.old Cause I've both files. Finally $sudo chmod +x /opt/google/talkplugin/GoogleTalkPlugin.old I closed and reopened chrome then started gmail tried video call -- black screen :-/ Ok so today finally google+ provided me with trouble shoot link and advised me: The plug-in won't install If you're having trouble installing the plug-in, or are receiving a message asking you to reinstall it, you should check to make sure your configuration is right. To do so simply: Check to make sure the Google Talk Plugin Video Accelerator and Google Talk NPAPI Plugin are enabled. If you're using Chrome you can type about:plugins in your browser to display your plug-ins. Make sure you're not using Internet Explorer 64-bit (this is a browser version that is 64 bit as opposed to 32 bit). Ensure that you don't have any "click to run" extensions enabled. If you're still experiencing this issue after checking your configuration you can follow these steps: Refresh the browser page. Close any running Google Talk plug-in processes. Close all open and running browser processes. Restart your computer. Uninstall and then reinstall the plug-in. Try a different browser such as Google Chrome or Mozilla Firefox. I looked in about:plugins for chrome and firefox: I don't have Google Talk NPAPI Plugin, does that matter? and I thought its installed with google talk plugin or no?

• How to find out if the screen is WLED or RGBLED on Dell Studio XPS 16?

  - by Abhijeet

  I just ordered the Dell Studio XPS 16 with i7 and 16" RGBLED screen. This upgrade from WLED LCD to RGBLED LCD charged me more $$. But now when I view the order online, it lists this part as "320-8335 Premium FHD WLED Display, Obsidian Black, 2.0 MP Webcam". When called Dell, the rep says this part is RGBLED screen and the "premium" is for RGBLED. I want to make sure they are shipping me the RGBLED screen and not the WLED. Is there any way to verify this after I receive (either from Device Manager or BIOS or somewhere in system settings)? Also, is there any published specifications / criteria that we can run (some third party software) on this monitor which can tell if this is WLED or RGBLED?

• Failed to start up after upgrading software

  - by Landy

  I asked this question in SuperUser one hour ago, then I know this community so I moved the question here... I've been running Ubuntu 10.10 in a physical x86-64 machine. Today Update Manager reminded me that there are some updates to install and I confirmed the action. I should had read the update list but I didn't. I can only remember there is an update about cups. After the upgrading, Update Manager requires a restart and I confirmed too. But after the restart, the computer can't start up. There are errors in the console. Begin: Running /scripts/init-premount ... done. Begin: Mounting root file system ... Begin: Running /scripts/local-top ... done.

• Ubuntu crashes with menu bar launcher freeze during software centre use

  - by UbunUser

  I recently reinstalled Ubuntu 12.04 LTS on a Dell Studio 1588 64-bit and ran into crashes as I was installing some software on the software centre. Before this, I had display/screen problems that I needed to fix so I will briefly describe that in case it has any connection to the crashes. The problem was of screen crash/flickering (related to ATI Mobility Radeon HD 5400x) when trying to adjust brightness and so I followed guidance from an earlier chain (question 131967) to (a) use jockey to install fglrx update driver (deactivate experimental beta driver) and (b) edit grub to add acpi_backlight=vendor dell_laptop.backlight=0 The crashes that happened (twice, while software centre was just finishing installation in the background) was that all tabs (on open Firefox window) stayed open along with cursor control with mousepad but all menu bars disappeared completely along with the launcher and the keyboard also turned unresponsive. So there seemed to be no way to close windows or shut down the computer except for a forced hard shut down of the system using the start button. This is very similar to Questions #167540 and #298843, which seem to be closed. Why is this happening? Is there some update or fix I need to make? Thanks!

• New computer hangs on shutdown/reboot, how to troubleshoot?

  - by Torben Gundtofte-Bruun

  My system is working perfectly but it freezes during shutdown/reboot/suspend/hibernate: All windows and the menu bar disappear but the desktop wallpaper remains. It doesn't even show the shutdown screen (the one with the animated dots) where I could hit ESC and watch the shutdown console text. The system is brand-new and fully updated using Update Manager. How can I determine what is causing the freeze? Is there a log I can investigate? How can I fix this? I see no obvious cause of the freeze. The only USB attachment is a mouse/keyboard; I don't have any external storage attached; and I don't have any programs running (the machine freezes even when doing shutdown right from the login screen). What I've tried so far: Based on other questions (this, this, and this) that suggest some ACPI settings, I've tried sudo shutdown -h now to see whether the shutdown console text display offers any hints, but the system doesn't even get that far - it still freezes while the screen shown the desktop background image, without any toolbars. Only sudo shutdown --force works, but that's not a solution. Editing the grub menu to add acpi=off to the kernel didn't help. I guess there's not much point in trying the other (lesser) ACPI suggestions? Adding noapic to the grub entry had no discernible effect. Adding nolapic instead did something (I had removed the quiet option) - the system managed to continue further with the shutdown, right until the line Checking for running unattended-upgrades: which were the last characters on the screen. I've also checked the system BIOS, especially regarding power options, but didn't see anything out of the ordinary. Switching the BIOS standby setting from S3 to S1 didn't help. The standby setting can't be disabled, and there are no other ACPI-related settings AFAIK. BIOS reset didn't help. Not surprised; hadn't changed anything. I tried going to a virtual console (CtrlAltF1) as suggested by djeikyb and from there did a shutdown -h now and it froze there too, after this console output. I didn't try killing processes one at a time because I'm still too newbie to figure out how to do that. Booting with kernel 2.6.35.22 rather than 2.6.35.25 didn't help. Disabling the Nvidia drivers didn't help. Booting from Live CD (USB stick in fact) didn't help; it freezes the same way. Booting from Live CD, with acpi=off noapic nolapic didn't help either. Neither did just nolapic. So evidently this is not some custom setting in my install, but some sort of basic issue. MemTest competed in 1 hour without errors.

• Turn-based Client-Server Card Game - Unicast (TCP) or Multicast (UDP)

  - by LDM91

  I am currently planning to make a card game project where the clients will communicate with the server in a turn-based and synchronous manner using messages sent over sockets. The problem I have is how to handle the following scenario: (Client takes it turn and sends its action to server) Client sends a message telling the server its move for the turn (e.g. plays the card 5 from its hand which needs to placed onto the table) Server receives messages and updates game state (server will hold all game state). Server iterates through a list of connected clients and sends a message to tell of them change in state Clients all refresh to display the state This is all based on using TCP, and looking at it now it seems a bit like the Observer pattern. The reason this seems to be an issue to me is this message doesn't seem to be point-to-point like the others as I want to send it to all the clients, and doesn't seem very efficient sending the same message in that way. I was thinking about using multicasting with UDP as then I could send the message to all the clients, however wouldn't this mean that the clients would in theory be able to message each other? There is of course the synchronous aspect as well, though this could be put on top of the UDP I guess. Basically, I would like to know what would be good practice as this project is really all about learning, and even though it won't be big enough to encounter performance issues from this I would like to consider them anyway. However, please note I am not interested in using message oriented middleware as a solution (I have experience with using MOM and I'm interested in considering other options excluding MOM if TCP sockets is a bad idea!).

  I'm running Ubuntu 12.04 with ATI Radeon 6870 connected to my 40' Sharp TV. The video image is slightly jigged, like breaking a bit and slightly delayed. It just isn't smooth. The computer is very fast, like i7 with 12gb ram. I tried to run the same video with my mac laptop and on the tv with the same connection cable and it was running smoothly. i tried changing the video output in VLC to x11, increase caching, h264 skip loop filter to all, increase monitor refresh rate although it's already at 60 and it's an LCD tv. this is my xorg.conf : Section "ServerLayout" Identifier "amdcccle Layout" Screen 0 "amdcccle-Screen[3]-0" 0 0 EndSection Section "Module" Load "glx" EndSection Section "Monitor" Identifier "0-DFP9" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" Option "TargetRefresh" "60" Option "Position" "0 0" Option "Rotate" "normal" Option "Disable" "false" Option "PreferredMode" "1920x1080" EndSection Section "Monitor" Identifier "0-DFP10" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" Option "PreferredMode" "1280x1024" Option "TargetRefresh" "60" Option "Position" "0 0" Option "Rotate" "normal" Option "Disable" "false" EndSection Section "Device" Identifier "amdcccle-Device[3]-0" Driver "fglrx" Option "Monitor-DFP9" "0-DFP9" BusID "PCI:3:0:0" EndSection Section "Screen" Identifier "Default Screen" DefaultDepth 24 EndSection Section "Screen" Identifier "amdcccle-Screen[3]-0" Device "amdcccle-Device[3]-0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection

• Permissions needed to read event log messages remotely?

  - by Neolisk

  When running under a limited account, local event log messages are displaying fine, for remote computer I am getting this error: The description for Event ID ( xxxxx ) in Source ( yyyyy ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: zzzzz. Same remote computer works fine under domain administrator. I am currently experimenting with just the Event Viewer, by using Run As. Original issue is a PowerShell script which does Get-EventLog. Are there any special permissions that need to be in place to able to read event log messages remotely? Supposedly there is a simple solution in Windows 2008 and higher, i.e. just add user to Event Log Readers group. Is there anything like that for Windows 2003?

• Java: How to manage UDP client-server state

  - by user92947

  I am trying to write a Java application that works similar to MapReduce. There is a server and several workers. Workers may come and go as they please and the membership to the group has a soft-state. To become a part of the group, the worker must send a UDP datagram to the server, but to continue to be part of the group, the worker must send the UDP datagram to the server every 5 minutes. In order to accommodate temporary errors, a worker is allowed to miss as many as two consecutive periodic UDP datagrams. So, the server must keep track of the current set of workers as well as the last time each worker had sent a UDP datagram. I've implemented a class called WorkerListener that implements Runnable and listens to UDP datagrams on a particular UDP port. Now, to keep track of active workers, this class may maintain a HashSet (or HashMap). When a datagram is received, the server may query the HashSet to check if it is a new member. If so, it can add the new worker to the group by adding an entry into the HashSet. If not, it must reset a "timer" for the worker, noting that it has just heard from the corresponding worker. I'm using the word timer in a generic sense. It doesn't have to be a clock of sorts. Perhaps this could also be implemented using int or long variables. Also, the server must run a thread that continuously monitors the timers for the workers to see that a client that times out on two consecutive datagram intervals, it is removed from the HashSet. I don't want to do this in the WorkerListener thread because it would be blocking on the UDP datagram receive() function. If I create a separate thread to monitor the worker HashSet, it would need to be a different class, perhaps WorkerRegistrar. I must share the HashSet with that thread. Mutual exclusion must also be implemented, then. My question is, what is the best way to do this? Pointers to some sample implementation would be great. I want to use the barebones JDK implementation, and not some fancy state maintenance API that takes care of everything, because I want this to be a useful demonstration for a class that I am teaching. Thanks

• How can I use 2 monitors plus laptop with my Dell e6420 w/ Nvidia nvs 4200m

  - by KallDrexx

  I have just hooked up a 2nd external monitor to my Dell e6420 laptop with a Nvidia NVS 4200m graphics card, running Windows 8 64 bit. However, the computer won't let me have both monitors and the laptop display active at the same time. I installed the latest Nvidia graphics drivers (310.70) but it claims that my GPU can only support up to 2 monitors. Nivdia's website implies differently (as does various other laptops around the office). The monitors are connected both via DVI to my dell docking station that has multiple DVI ports. Both monitors are working correctly, I just can't get all 3 working together. Attempting to download the driver from dell fails, as their driver installer is broken apparently Any ideas?

• How can I make full-screen desktop applications only cover the snapped desktop?

  - by nhinkle

  In Windows 8, you can "snap" two apps next to each other, and one of those apps can be the legacy Windows desktop environment. A convenient application for this (or so I thought) would be to snap a chat client, small browser, or other app while watching content in full-screen on the desktop. The problem with this is that full screen desktop applications will take over the entire screen, even if the desktop is snapped to only occupy 3/4th of the display. What I would like is some way to force "full screen" desktop apps to only cover the snapped desktop area, and to truly go full screen if the desktop is snapped to full-width. Is there some way to configure this? If that didn't make sense, let me illustrate with pictures: Desktop in snapped view with SU chat in mini-browser: What happens when you click "full screen": What I want to happen when I click "full screen" (note this is digitally altered, not a real screenshot)

• Best scripting language for project [on hold]

  - by Dave

  This is a subjective question, but I don't know where else to ask it. I'd appreciate it if someone could direct me to an appropriate scripting language for my project. I'm a little new at this so I'd appreciate any help. The project is a website that will display a list of photo subject groups (such as "nature" "people" "sports" etc) on the home page. The photos will all be in subdirectories of the main photo directory (photos) and each subject group will represent a subdirectory in photos. For example in directory photos there might be 3 subdirectories, "nature" "people" "sports" and in each of those subdirectories there will be the actual photos. The idea is that when the website owner wants to update/add/delete a subject group all he has to do is add, delete or update a subdirectory of the photos directory. This means, I think, that I need a scripting language that can read the directories and files in the website and then send a web page with the information in it. What is the simplest and easiest scripting language to do this in? Any ideas? Thanks

• Ubuntu 12.04 stopped recognizing my BenQ monitor and reduced resolution to 1024x768

  - by Omri

  A few days ago I installed Ubuntu 12.04 32bit Desktop. It recognized my hardware without a problem (at least that I know of) and all worked fine. I left my system running (it is at work) through the night because it is also working as a database server and when I came today to work the resolution was 1024x768 (the monitor recommends 1920x1080) even though in the Display section of the System Settings it was recognized as BenQ, and no higher resolution was offered. After a restart, the monitor name changed from BenQ to Unknown. This is a desktop computer. I also installed gtk-redshift and f.lux. I checked Additional Drivers to see if there is something I can install but it didn't find anything. I tried to Google it but I didn't find anything about a monitor stopping being recognized after it was already working. I did enable some PPAs yesterday, namely webupd8, mozillateam/thunderbird-stable and some other, and I also followed the instructions to patch the NotifyOSD to be more friendly: sudo add-apt-repository ppa:caffeine-developers/ppa sudo add-apt-repository ppa:leolik/leolik sudo apt-get update sudo apt-get upgrade sudo apt-get install libnotify-bin pkill notify-osd sudo add-apt-repository ppa:nilarimogard/webupd8 sudo apt-get update sudo apt-get install notifyosdconfig I now purged both caffeine-developers and leolik PPAs in the hope it will help, but no change. Has there been a change in the packages that could introduce this problem? Any help will be very appreciated :-) Omri

• How can I get black window borders in Windows 8?

  - by sean e

  In Windows 8, when I go into Control Panel\Appearance and Personalization\Personalization\Window Color and Appearance the amount of control over window colors is greatly reduced as compared to Windows 7. The color controls do not allow you to make Window borders display in black. Is there some other way to set the window border color in Windows 8? Edit 1: Clearly the standard way does not work in Windows 8. The question is, is there another way? Perhaps through the registry for example? Edit 2: I tried copying the values in HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM from my Win7 system to the Win8 system without success (killing the 2 DWM processes after each change - they are automatically restarted and do use the new values).
