  • Gnome/X logs off immediately after login -- which logfiles are relevant?

    - by joebuntu
    I've been tinkering with fingerprint-gui as well as X/xrandr resolution settings. When I start my machine, it boots up normally. As soon as X and gnome have finished starting, it logs me off automatically and brings me back to the gdm login prompt with the user list. Then I am, however, able to log in using "Ubuntu Desktop Fail-safe". I've checked the list of start-up applications, but everything seems fine there. I can't yet put my finger on what exactly might be responsible for this: X, gnome or some messed up pam.d settings. So far I've checked /var/logs/X11/xorg.0.log, /var/logs/auth.log and ~/.xsession-errors. In addition, I don't quite seem to understand the "interplay" between X, GDM, GNOME, GNOME-policykit, PAM.d and all that. Are there any other relevant log files that could point me to what's broken? Specs: Ubuntu 10.10 Maverick Meerkat IBM/Lenovo Thinkpad R60, ATI Radeon x1400 Mobility all updates installed Linux User 1 year+,

  • Is this a valid HTTP response? [migrated]

    - by fatmck
    I am writing a web server using C++, which responds the following for all requests: static std::string rsp[] = { "HTTP/1.1 200 OK\r\n", "Server: WebServer\r\n", "Content-Type: text/html\r\n", "Content-Length: 3\r\n", "Connection: close\r\n", "\r\n", "123" }; the content "123" can be successfully shown in browser. But when I use apache-ab to do a test, ab always show errors like this: ab -n 1 -c 1 http://127.0.0.1:1080/ apr_socket_recv: Connection reset by peer (104) I thought that I'm closing the socket too quickly, so I commented the close() function. But ab just hold, ab seems to be waiting for a complete response.

  • reinstalling totem 3.0.1 from source

    - by user1537727
    I have totem 3.0.1 installed on my system, but I wish to install from source the same and when I do so i am presented with the following dependency errors. How can this be possible? configure: error: Package requirements ( glib-2.0 >= 2.27.92 gio-2.0 >= 2.27.92 gtk+-3.0 >= 2.99.3 gdk-x11-3.0 >= 2.99.3 gmodule-2.0 totem-plparser >= 2.32.4 gstreamer-tag-0.10 >= 0.10.26 cairo) were not met: No package 'totem-plparser' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables DEPENDENCY_CFLAGS and DEPENDENCY_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details.

  • Is there any map maker for javaME game?

    - by user1494517
    For the past two weeks I was trying to make a map maker for my java ME 2D RPG game. I failed because i get errors using slick TWL and the forum for this is inactive. So I just wondered is there anyone that knows slick TWL (Themable Widget Library)? Or maybe do you know a good MapMaker where i could upload my map elements build a map and get numbers to use them for building map with LayerManager class? Already found one http://sourceforge.net/projects/tilemapeditor2d/. But the thing is my map elements are in different .png images. In one of those images there is 16 elements (trees water and etc) and those kind of images are 29. So it would be hard to build a map with LayerManager Well I was thinking putting everything into one image and that way it would be simplier.

  • After a domain change, what can I do to recover lost traffic, rankings, impressions etc? [duplicate]

    - by Felix
    This question already has an answer here: How do I rename a domain and preserve PageRank? 3 answers I moved my site to a legacy exact-match domain I purchased about a couple of months ago. I have seen significant reduction in traffic, impressions, and rankings. I did all the right steps/best practices: change of address in GWT, map old site hierarchy and match to new site for 301 redirects etc. Indexation has gone through the Google process: old site has all but dissappeared from he index and new site is indexed, albeit with some 404 errors which I am addressing. Does anyone else who has gone through eh domain change process have any thoughts/advice? Thanks!

  • To track or not to track user created images for display in a dynamic website?

    - by Question Overflow
    I have a website that allows user to upload and display images. Currently, I am not using a database to track these user images. A folder having the user id as the folder name is created for each user and under each folder, the image files are labelled numerically with filenames ranging from 01.jpg to 20.jpg. Up to 20 such images can be displayed on each user page. I am using javascript to hide these images in case of any of them is absent. I have seen many websites having user images with unique random filenames and possibly tracking these files with a database Since obscurity is not something that I need for these web accessible images, is there any reason why I should track them with a DB? I am not sure if a reduction of 404 errors is a good enough reason to justify the added complexity of maintaining a database or can anyone enlighten me?

  • Netbeans 7.0.1 installed but won't run

    - by Dave M G
    I installed Netbeans 7.0.1, and I've made sure to install all the JDKs and JREs I could find. It installed without errors. I also saw this question and made sure I followed all the instructions there as well. I never got any error messages of any kind. So far as I know, it installed okay. However, when I try to run Netbeans, I get no response. If I run it from the command line, after about 30 seconds, the prompt just comes back. There's no error message of any kind to let me know what's wrong. $ /bin/sh "/home/dave/netbeans-7.0.1/bin/netbeans" $ What's the issue, and how do I get Netbeans to run?

  • Can't copy file (I/O error) Ubuntu Server

    - by QxQ
    I'm running Ubuntu Server 12.04, and basically found out that a couple of files aren't behaving like they should. The file name is r.-1.-1.mca, and I've tried using this terminal command sudo cp r.-1.-1.mca ../ The hard drive is working/thinking for a while, then spits this back out: cp: reading `r.-1.-1.mca': Input/output error cp: failed to extend `../r.-1.-1.mca': Input/output error I have another file behaving like this. My guess is that these files are corrupt, so I tried running the server in recovery mode and it told me to check the file system. However, it didn't come up with any errors. Is there a way to repair these files so I can use them normally again?

  • How to run/test JavaScript? [closed]

    - by user702
    I'm reading David Flanagan's "JavaScript: The Definitive Guide, 6th ed". It only actually tells users how to run JS code on page 311, where users are told of the following solutions: "Client-side JavaScript code is embedded within HTML documents in four ways: Inline, between a pair of <script> and </script> tags From an external file specified by the src attribute in a <script> tag In an HTML event handler attribute, such as onclick or onmouseover In a URL that uses the special javascript: protocol." I was wondering what professional JS developers use to write and test their code: Do they use a good text editor with syntax high-lighting + autocompletion, hit F5 in the browser to reload the page every time they make a change, and use some add-on in the browser to investigate errors? Or are there full-fledged IDE's similar to MS VisualStudio for non-web languages?

  • Dual 7950, freezes during startup

    - by Hiro
    I have two identical video cards right now. Xubuntu will boot up no problem if I only have one card installed. If I install the 2nd card it will just hang midway thru the loading screen. Regardless of which card I use and which position on the motherboard, it will freeze if I have both installed. I've tried installing the proprietary drivers, both fglrx and fglrx-updates, still freezes in the same spot. Uninstalled those and went back to the default ones. The only way I can get a terminal is by booting into failsafe mode. Booting using 13.10 i386 on a USB stick gives me some errors related to what I think is the 2nd video card: [drm:r600_ring_test] ERROR radeon: ring 1 test failed (scratch(0x850C)=0xCAFEDEAD) [drm:r600_dma_ring_test] ERROR radeon: ring 3 test failed (0x02FFFF6B) radeon 0000:0200.2 disabling GPU acceleration"

  • Chessin's principles of RAS design

    - by user12608173
    In late 2001 I developed an internal talk on designing hardware for easier error injection, prevention, diagnosis, and correction. (This talk became the basis for my paper on injecting errors for fun and profit.) In that talk (but not in the paper), I articulated 10 principles of RAS design, which I list for you here: Protect everything Correct where you can Detect where you can't Where protection not feasible (e.g., ALUs), duplicate and compare Report everything; never throw away RAS information Allow non-destructive inspection (logging/scrubbing) Allow non-destructive alteration (injection) (that is, only change the bits you want changed, and leave everything else as is) Allow observation of all the bits as they are (logging) Allow alteration of any particular bit or combination of bits (injection) Document everything Of course, it isn't always feasible to follow these rules completely all the time, but I put them out there as a starting point.

  • Failed to allocate memory - What is it trying to say?

    - by asprin
    In my early days of programming I often used to get memory related fatal errors in the following format: Fatal error: Allowed memory size of <some big number> bytes exhausted (tried to allocate <some small number> bytes) in /path/to/filename.php on line <some line number> I'm a little embarrassed to state that even though I have figured out how to solve them and take steps to avoid them altogether, I'm still not quite sure what exactly does the message translate to in simple words. For example, if I get a message such as: Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 4000 bytes) in ........ on line 34 As things stand at the moment, I assume it to be stating that the script consumes 67108864 bytes of data, but only 4000 bytes are available during runtime. Am I right in my assumption? If not, what's the correct interpretation?

  • Compiling old versions of R (2.11 or older) on Ubuntu 13.10 (or newer)?

    - by user283293
    I am trying to compile an old version of R (2.11.1, specifically). "Why?", you might ask. Well, I have a program I am trying to run (that was not written by me, but I am hoping to use in my research) that was written in "old" R, and the program writer has specifically mentioned that R-2.11.1 or older must be used. I have run ./configure with no obvious errors (the entire output being far too long to post here, but I have been warned that I cannot make PDF, DVI, or HTML versions of the help pages, which I'm not too concerned about). Next, when I pass the make command, I am met with the following error (after a long stream of successful commands): Warning in solve.default(rgb): unable to load shared library '/home/sbowerma/Programs/R-2.11.1/modules//lapack.so': /home/sbowerma/Programs/R-2.11.1/lib/libRlapack.so: undefined symbol: _gfortran_compare_string Error in solve.default(rgb) : lapack routines cannot be loaded Error: unable to load R code in package 'grDevices' Execution halted However, I have confirmed that the library lapack.so is, in fact, in the exact position it is supposed to be.

  • Missing error handling in Streaming-AJAX-Proxy Log

    - by Michael Freidgeim
    We are using AjaxProxy(FROM http://www.codeproject.com/KB/ajax/ajaxproxy.aspx) on our web site, but started to notice errors accessing log.txt file. I found that the file is created by Log class and doesn't have ability to switch it off and error handling. I've added reading file name from configuration and try/catch block   public static class Log     {         private static StreamWriter logStream;         private static object lockObject = new object ();     public static void WriteLine(string msg)         {                       string logFileName = ConfigurationExtensions.GetAppSetting("AjaxStreamingProxy.LogFile" ,"");                       if (logFileName.IsNullOrEmpty())                             return;                       try                      {                             if (logStream == null )                            {                                    lock (lockObject)                                   {                                           if (logStream == null )                                          {                            logStream = File.AppendText(Path .Combine(AppDomain.CurrentDomain.BaseDirectory, logFileName));                                          }                                   }                            }                            logStream.WriteLine(msg);                      }                       catch (Exception exc)                      {                             string ignoredMsg = String .Format("The error occured while logging {0}, but processing will continue.\n {1} ", exc);                             LoggerHelper.LogEvent(ignoredMsg, MyCategorySource, TraceEventType .Warning, true);                      }         }

  • "Sorry, Ubuntu 12.04 has experienced an internal error."

    - by malapradej
    I have recently upgraded to Precise and had some errors. It seems to be quite random and with differences in the error reports. I have duly sent the reports hoping the system will have found the problem and sorted itself out. After the second error I am following the wizards (software...) advice and seeking help. The 1st time it happened I jotted down the following: ExecutablePath /usr/lib/tracker/tracker-extract LaunchPad bug 950765 AMD64 The second time the following: ExecutablePath /usr/share/appart/appart-gpu-error-intel.py "Possible GPU hang........" sandybridge-m-gt2 LaunchPad bug 981261 If there is anyone that can help it is much appreciated. I did not really want to upgrade at this stage, but was forced to due to the latest version of python-numpy in precise. You win some, you loose some....
