  • Failed 12.04 installation

    - by Rob Sayer
    I tried installing Ubuntu 12.04 today. Not an upgrade, a new installation. It didn't work. My computer specs: Computer: Compaq presario CQ-104CA OS: Windows 7 Home 64 bit CPU: AMD V140 BIOS: latest Graphics: amd m880g with ati mobility radeon hd 4250 Wireless: atheros ar9285 Internal HD:SATA I wasn't connected to the internet at the time ... I know of a number of people who have installed ubuntu unconnected and just updated later. It seemed to go normally until I got to the part where I chose to install dual boot linux/windows. Then, the screen went black and the following test appeared (I left out the [OK]'s): checking battery state starting crash report submission daemon stating cpu interrupts balancing daemon stopping system V runlevel compatibility starting configure network device security stopping configure network device security stopping cold plug devices stopping log initial device creation starting enable remaining boot-time encrypting devices starting configure network device security starting save udev log and update rules stopping save udev log and update rules stopping enable remaining boot-time encrypted block devices checking for running unattended-upgrades acpid: exiting speech-dispatcher disabled: edit /etc/default/speech-disorder At this point, the CD is ejected. Then nothing. If I press the return key, it boots Windows. I don't think that's what's supposed to happen. Thinking the cd media or dvd drive may have been faulty, I downloaded the .iso again and made a bootable USB stick, as per your instructions. This time there was no cryptic crash screen. It just booted windows. I can't find any log files it may have left. Thinking the amd64 version may have been the wrong one, I tried downloading the x86 version. Same thing, both from cd and usb drive. Note I downloaded both files twice. I doubt it was a corrupted d/l. This is supposed to be a simple, transparent install. I went to the time and trouble of looking up my devices and drivers re ubuntu beforehand, and was prepared to do some configuration, though I know someone who has the same wireless device and his worked righted out of the box. But I spent over 3 hours trying to install it with only the above to show for it.

  • Is it okay to call exception-triggered debugging "post-mortem debugging"?

    - by cool-RR
    I heard the term "post-mortem debugging", and Wikipedia says it's debugging done after the program has crashed. I often debug Python apps using a debugger that stops execution once an important-enough exception has been raised. Then I can use the debug probe to investigate. Does this count as "post-mortem debugging"? Because the program doesn't really crash. EDIT: If the answer is no, then what name would you use for the kind of debugging that I described?

  • Macbook Air freezes while running Ubuntu 13.10

    - by jjesse
    Ok folks I'm trying to setup my Macbook Air to run Ubuntu 13.10 (note: I normally using Kubuntu but currently running Ubuntu). I have run all of the updates for the system as of this posting. This happens regardless of the application I have open (Firefox, Terminal, Software Updater). The system will freeze, become unresponsive and then kick me back to the login screen. I don't see a crash notification or anything to send as troubleshooting so I don't know where to start

  • Can't sync music on Nexus 4 with rhythmbox

    - by luca992
    My LG Nexus 4 phone running Andriod 4.4.3 will not sync music with rhythmbox, banshee, or clementine with my laptop running Ubuntu 14.04. When attached via USB2 or USB3 I can mount the file system on the phone without issue and can manually transfer files but attempting to sync my nexus with any of the three music players I listed causes them to crash. I realize it is probably some mtp issue. But I cannot figure out why the music players cannot connect to my nexus and nautilus has no problem doing so.

  • Wubi no longer supports install to fakeraid?

    - by Ryan
    About a week ago I used wubi to install ubuntu onto one of my two raid1 devices in windows 7. I tried to do the same this week on the same mobo/drive combo and now I can't get it to install. It gives me first an "invalid prefix" during the install and then says "completing install" followed by a crash into busybox with a warning that the raid can't be mounted because it already was mounted. Has there been a change in wubi or something in the recent past?

  • HTG Explains: Why Do So Many Apps Want to Send Usage Statistics, and Should I Let Them?

    - by Chris Hoffman
    Many programs want to send usage statistics, error logs, and crash reports — data about how you use the application and what problems occurred — to their servers. Some people disable these options, but should you? We’ll look at the exact types of data applications want to send, what developers do with it, whether any sensitive personal data is being passed along, and the advantages and disadvantages to enabling these options.

  • High traffic chat - how to check if there is new message and show it for all users

    - by user2633999
    I already had question about this but obviously it was not accepted very well, apparently too long when it's actually more information so you could have given me better answer. Ok, I will be much clearer now. Best possible logic to develop scalable chat in terms of stability, storing/reading messages on chat, updating chat on new message for all users etc.? I have most of this developed, the logic I think I miss is -- check if there is new message and show it for all users. I have this implemented but it crashes the site due to its traffic of 300k-400k people, so that's my main question. The chat is PHP based and uses Pusher (www.pusher.com) for instant messaging but it lacks what I need because it's more like a websocket. I'm using hardcoded files to keep messages (want to avoid database as much as possible). It's a no extension type of file, I'm sure you know. I'm getting crash with $fp = fopen(..., "w"); // pretend ... is the path and filename fwrite($fp, $msg); //hardcode the message fclose($fp); where $msg is the message itself. I'm having 1 file per message. I show last 150 messages = 150 file accesses and reads, yeah it's too much I guess. I have better logic now which I'm pursuing and that is 1 file with last 50-100 messages at all time. Sure it should be much better. How does it crash, that's the trickiest part because everything seems ordinary, believe me it is difficult to determine what exactly crashes the site, but in like 5 minutes when I try to open the site it's gone, then I put the old content without chat and is back online again. I'm having jquery post every 1 second to check if there is new message. I'm using timestamp in a special file where I keep the time last message was sent and if ((time() - time in file) <= 2) = reload last 150 messages including the last one. Too much input/output, write/read or however to say it I think is what crashes the site.

  • How do I downgrade rhythmbox v2.98?

    - by fossfreedom
    I've been testing out the new WebUpd8 PPA for Rhythmbox which I used to upgrade from Rhythmbox v2.97 to v2.98. However, when I added this PPA, when using my favourite plugins replaygain and coverart-browser, Rhythmbox crashes with a segmentation fault. Worse, when this crash happens, my Unity desktop becomes unstable, with various applications failing to start with similar segmentation faults. Does anybody know the reason for this - but more importantly how to resolve this?

  • Ubuntu 11.10 error message at startup after clean install

    - by user999687
    I have just installed Ubuntu 11.10 (did a fresh install and erased 11.04). After the reboot it appeared a log on the screen, saying all the starting services on the left and [OK] on the right. However, two particular entries, starting automatic crash report installation and starting restore sound card(s') mixer state(s) were set on [FAIL]. After that, Ubuntu did not boot. Is there any way that i can skip those two entries and boot Ubuntu?

  • Requring static class setter to be called before constructor, bad design?

    - by roverred
    I have a class, say Foo, and every instance of Foo will need and contain the same List object, myList. Since every class instance will share the same List Object, I thought it would be good to make myList static and use a static function to set myList before the constructor is called. I was wondering if this was bad, because this requires the setter to be called before the constructor? If the person doesn't, the program will crash. Alternative way would be passing myList every time.

  • jtreg update, March 2012

    - by jjg
    There is a new update for jtreg 4.1, b04, available. The primary changes have been to support faster and more reliable test runs, especially for tests in the jdk/ repository. [ For users inside Oracle, there is preliminary direct support for gathering code coverage data using jcov while running tests, and for generating a coverage report when all the tests have been run. ] -- jtreg can be downloaded from the OpenJDK jtreg page: http://openjdk.java.net/jtreg/. Scratch directories On platforms like Windows, if a test leaves a file open when the test is over, that can cause a problem for downstream tests, because the scratch directory cannot be emptied beforehand. This is addressed in agentvm mode by discarding any agents using that scratch directory and starting new agents using a new empty scratch directory. Successive directives use suffices _1, _2, etc. If you see such directories appearing in the work directory, that is an indication that files were left open in the preceding directory in the series. Locking support Some tests use shared system resources such as fixed port numbers. This causes a problem when running tests concurrently. So, you can now mark a directory such that all the tests within all such directories will be run sequentially, even if you use -concurrency:N on the command line to run the rest of the tests in parallel. This is seen as a short term solution: it is recommended that tests not use shared system resources whenever possible. If you are running multiple instances of jtreg on the same machine at the same time, you can use a new option -lock:file to specify a file to be used for file locking; otherwise, the locking will just be within the JVM used to run jtreg. "autovm mode" By default, if no options to the contrary are given on the command line, tests will be run in othervm mode. Now, a test suite can be marked so that the default execution mode is "agentvm" mode. In conjunction with this, you can now mark a directory such that all the tests within that directory will be run in "othervm" mode. Conceptually, this is equivalent to putting /othervm on every appropriate action on every test in that directory and any subdirectories. This is seen as a short term solution: it is recommended tests be adapted to use agentvm mode, or use "@run main/othervm" explicitly. Info in test result files The user name and jtreg version info are now stored in the properties near the beginning of the .jtr file. Build The makefiles used to build and test jtreg have been reorganized and simplified. jtreg is now using JT Harness version 4.4. Other jtreg provides access to GNOME_DESKTOP_SESSION_ID when set. jtreg ensures that shell tests are given an absolute path for the JDK under test. jtreg now honors the "first sentence rule" for the description given by @summary. jtreg saves the default locale before executing a test in samevm or agentvm mode, and restores it afterwards. Bug fixes jtreg tried to execute a test even if the compilation failed in agentvm mode because of a JVM crash. jtreg did not correctly handle the -compilejdk option. Acknowledgements Thanks to Alan, Amy, Andrey, Brad, Christine, Dima, Max, Mike, Sherman, Steve and others for their help, suggestions, bug reports and for testing this latest version.
