  • Firefox 4 crashing in VNC

    - by MacThePenguin
    On my desktop PC I've been using Kubuntu 10.04 for about a year. Recently I've updated Firefox to version 4 using aptitude and the mozilla-team/firefox-stable repository. Since then, I can't run it when I'm logged in through a VNC session. Firefox crashes immediately: when I try to run it from the console I get this error: ###!!! ABORT: X_ShmPutImage: BadShmSeg (invalid shared segment parameter); 3 requests ago: file /build/buildd/firefox-4.0.1+build1+nobinonly/build-tree/mozilla/toolkit/xre/nsX11ErrorHandler.cpp, line 203 ###!!! ABORT: X_ShmPutImage: BadShmSeg (invalid shared segment parameter); 3 requests ago: file /build/buildd/firefox-4.0.1+build1+nobinonly/build-tree/mozilla/toolkit/xre/nsX11ErrorHandler.cpp, line 203 Firefox works fine when I run it directly from the PC. Firefox 3.x worked fine also from a VNC session. I tried to turn off the hardware acceleration from the Firefox preferences, but that doesn't fix the problem. firefox --sync, firefox -safe-mode and firefox -ProfileManager also crash the same way. Any idea how to troubleshoot this? Thanks. Edit: additional info. I run vnc (RealVNC 4.1.1) from xinetd, this is the config I use: service Xvnc { type = UNLISTED disable = no socket_type = stream protocol = tcp wait = yes user = root server = /usr/bin/Xvnc4 server_args = -inetd :1 -desktop vnc5901 -query localhost -geometry 1160x675 -depth 16 -once -DisconnectClients=0 -NeverShared passwordFile=/path/to/vnc/password -render port = 5901 }

  • .wine-pipelight folder not present

    - by DaimyoKirby
    Following the instructions on the pipelight installation page, I installed pipelight on Ubuntu 14.04. However, upon opening firefox the .wine-pipelight folder isn't present in my home folder, and I get the following errors: [PIPELIGHT:LIN:unknown] attached to process. [PIPELIGHT:LIN:unknown] checking environment variable PIPELIGHT_SILVERLIGHT5_1_CONFIG. [PIPELIGHT:LIN:unknown] searching for config file pipelight-silverlight5.1.

I've reinstalled quite a few times and ran through many of the common fixes offered on the pipelight Launchpad pages and here on AskUbunta and still it fails to run. Is there a reason why this folder isn't present, or why I'm getting these errors? Edit: Oddly enough, the .wine-pipelight folder is created wtih I open Nitro, although this still doesn't fix the issue.

  • What are the packages/libraries I should install before compiling Python from source?

    - by Lennart Regebro
    Once in a while I need to install a new Ubuntu (I used it both for desktop and servers) and I always forget a couple of libraries I should have installed before compiling, meaning I have to recompile, and it's getting annoying. So now I want to make a complete list of all library packages to install before compiling Python (and preferably how optional they are). This is the list I compiled with below help and by digging in setup.py. It is complete for Ubuntu 10.04 and 11.04 at least: build-essential (obviously) libz-dev (also pretty common and essential) libreadline-dev (or the Python prompt is crap) libncursesw5-dev libssl-dev libgdbm-dev libsqlite3-dev libbz2-dev More optional: tk-dev libdb-dev Ubuntu has no packages for v1.8.5 of the Berkeley database, nor (for obvious reasons) the Sun audio hardware, so the bsddb185 and sunaudiodev modules will still not be built on Ubuntu, but all other modules are built with the above packages installed. Python 2.5 and Python 2.6 also needs to have LDFLAGS set on Ubuntu 11.04 and later, to handle the new multi-arch layout: export LDFLAGS="-L/usr/lib/$(dpkg-architecture -qDEB_HOST_MULTIARCH)" For Python 2.6 and 2.7 you also need to explicitly enable SSL after running the ./configure script and before running make. In Modules/Setup there are lines like this: #SSL=/usr/local/ssl #_ssl _ssl.c \ # -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \ # -L$(SSL)/lib -lssl -lcrypto Uncomment these lines and change the SSL variable to /usr: SSL=/usr _ssl _ssl.c \ -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \ -L$(SSL)/lib -lssl -lcrypto Python 2.6 also needs Modules/_ssl.c modified to be used with OpenSSL 1.0, which is used in Ubuntu 11.10. At around line 300 you'll find this: else if (proto_version == PY_SSL_VERSION_SSL3) self->ctx = SSL_CTX_new(SSLv3_method()); /* Set up context */ else if (proto_version == PY_SSL_VERSION_SSL2) self->ctx = SSL_CTX_new(SSLv2_method()); /* Set up context */ else if (proto_version == PY_SSL_VERSION_SSL23) self->ctx = SSL_CTX_new(SSLv23_method()); /* Set up context */ Change that into: else if (proto_version == PY_SSL_VERSION_SSL3) self->ctx = SSL_CTX_new(SSLv3_method()); /* Set up context */ #ifndef OPENSSL_NO_SSL2 else if (proto_version == PY_SSL_VERSION_SSL2) self->ctx = SSL_CTX_new(SSLv2_method()); /* Set up context */ #endif else if (proto_version == PY_SSL_VERSION_SSL23) self->ctx = SSL_CTX_new(SSLv23_method()); /* Set up context */ This disables SSL_v2 support, which apparently is gone in OpenSSL1.0.

  • New technical product guide for Sun Ray clients

    - by Jaap
    In the Oracle online documentation system a new Sun Ray clients Technical Product guide has been published. The document provides detailed information about the similarities and differences between the three Sun Ray client hardware models: Sun Ray 3, Sun Ray 3 plus and Sun Ray 3i. From the description of the Technical Product guide I want to quote the following section: "......Since Sun Ray 3 Series Clients have no local operating system and require no local management, they eliminate the complexity, expenses, and security vulnerabilities associated with other thin client and PC solutions. ......" This is always one of the great advantages of Sun Ray clients compared to other thin clients (which are actually low-fat PCs where you have to manage thin client OS images). The guide lists the features and technical specifications of the Sun Ray Client such as number of ports, chassis, graphics, network interfaces, power supply, operating conditions, MTBF, reliability, and other standards. The guide also contains a separate chapter about environmental data. As you may know, the Sun Ray 3 Series clients are designed specifically to be sensitive to a spectrum of environmental concerns and standards, from materials to manufacturing processes to shipping, operation, and end of life. The Sun Ray 3 Series clients complies to environmental standards and certifications such as Energy Star 5.0, EPEAT, WEEE and RoHS (see the Oracle policy for RoHS and REACH).

  • Trouble installing Server 12.10 - Dead keyboard, Blank Screen, Network Config

    - by Mikey
    Installing 12.10 server from cd - minimal installation: basic system, ssh server,postgreSQL, manual updates. Hardware is brand new HP server that also runs Win 2003 Server Standard as a DNC excellently - I installed the grub boot manager on the primary partition and it is working fine - can boot to Win or Ubuntu without issue. Everything seemed to go OK on the installation - BUT when I restarted the system after install and booted to Ubuntu, I got the command prompt for Ubuntu, but the keyboard was UNREPSONSIVE - dead. There is nothing wrong with the keyboard - works fine if I boot to Win. With a completely unrepsonsive keyboard I had to hit the power switch - when I restarted and booted to Ubuntu, Ubuntu started but no command prompt came up at all - just black screen. I powered down and rebooted to advanced Ubuntu options - it tried to reinstall/initliaze a long list of packages - when it got to 'waiting for network configuration' it waited, then a message 'waiting 60 seconds for network configuration'... it waited 60 seconds and then I got a 'failed to configure network message' and it continued. Finally it finished, I hit enter and got to a prompt - but again, keyboard UNREPSONSIVE - dead. I went through this several times - tried 'repairing broken installation' option and also reinstalling entirely - always same results. I am flummoxed. The only clue I have is that for the Windows DNC config, the IP address is static - not via DHCP. But I don't think that should impact Ubuntu at all - perhaps I am mistaken. What is wrong?

  • File saving disabled 'Saving has been disabled by system admin'

    - by Gubuntu
    I have coded my own html website recently, and today wished to add a Google calender object to it. I have not put this website on the web because it is for my own personal use and I can't buy a domain. So I just have a folder on my pc that I load the index.html from now and then. As I was saying, today I got an error while trying to save the Google calender object in. I am system admin on my PC, in fact no one else uses but me, except when I have friends round, but for once my PC seems to think I'm some standard account user, because I couldn't save. I thought of clicking close and seeing if it came up with save as, but it didn't, it said 'Are you sure you want to close without saving?' or something along the lines of that, and 'Saving has been disabled by your system admin.' I couldn't do anything. I tried looking at the settings of the file, and it had me as read only in one of the selections, so I changed that to read & write, but to no avail. I did not save as root when I last edited the file, so I don't get what's going on. Help! P.S. This is on Ask Ubuntu not Superuser because it is on my Ubuntu PC and it appears to be a problem with Ubuntu not root or hardware.

  • 2D graphics - why use spritesheets?

    - by Columbo
    I have seen many examples of how to render sprites from a spritesheet but I havent grasped why it is the most common way of dealing with sprites in 2d games. I have started out with 2d sprite rendering in the few demo applications I've made by dealing with each animation frame for any given sprite type as its own texture - and this collection of textures is stored in a dictionary. This seems to work for me, and suits my workflow pretty well, as I tend to make my animations as gif/mng files and then extract the frames to individual pngs. Is there a noticeable performance advantage to rendering from a single sheet rather than from individual textures? With modern hardware that is capable of drawing millions of polygons to the screen a hundred times a second, does it even matter for my 2d games which just deal with a few dozen 50x100px rectangles? The implementation details of loading a texture into graphics memory and displaying it in XNA seems pretty abstracted. All I know is that textures are bound to the graphics device when they are loaded, then during the game loop, the textures get rendered in batches. So it's not clear to me whether my choice affects performance. I suspect that there are some very good reasons most 2d game developers seem to be using them, I just don't understand why.

  • How to check system performance?

    - by Woltan
    Hi all, I am a new Ubuntu user and really like the look and the features of the OS. However, I have a feeling that the performance could be better. With that I mean: Somehow the scrolling within firefox of sites seems laggy. I do not know how I should measure it but there is a difference. Not that it is unusable but it is aggravating. Java programs are running really slow. As a comparison (I know it is not a fair one), I tried to run a game using wine. The graphic specifications using windows were much higher (1600x1200) with a high level of detail, and in ubuntu with the lowest level of detail 1024x768 was the maximum. (My graphics card is a GeForce GTS 450 with 1gb RAM) Coming to my question: Is there a way to measure the performance of 3D acceleration, java applets, firefox scrolling etc. with a tool and compare it with lets say a windows OS or other users having almost the same hardware? Maybe it is a setup issue where some fundamental drivers are missing or something!? Any help, link, suggestion is appreciated! Cherio Woltan

  • Stop Your Mouse from Waking Up Your Windows 7 Computer

    - by The Geek
    If you use Sleep Mode on your PC, have you ever noticed that moving your mouse will wake the computer from sleep mode? If you would prefer to only have the PC wake up when you hit a key instead, there’s a simple tweak. Just type Mouse into the start menu search box, or the Control Panel search box, and then open up the Mouse Properties panel. Find the Hardware tab, select your mouse in the list, and then click the Properties button. You’ll have to click the “Change settings” button before you can see the Power Management tab… And now, you can uncheck the box from “Allow this device to wake the computer”. That’s all there is to it.

  • Lightest weight ubuntu desktop for text editing in big terminal windows?

    - by Kevin Pauli
    I have an older windows laptop onto which I'm installing ubuntu within a VM. My goal is just to use terminal-based linux tools such as vim and shell scripting. I don't give a hoot about any gui for this box. So I first installed ubuntu minimalcd and chose "Basic Ubuntu Server". Upon boot, the text-based terminal came up and I logged in, but the problem is it only gives me 80 columns. I want to do terminal mode vim but have a couple hundred columns to take advantage of my large monitor. If you happen to know how to do that, please see my question here . This post is assuming that the other question is not answerable, and that I will need a desktop to get more than 80 columns in a terminal window. So if that is the case, I want the lightest weight one possible, because this is older hardware and all I want is the ability to have nice big text-based terminal windows for editing text. From the ubuntu minimal CD, I see options for Edubuntu, Kubuntu, etc. Which one of the available desktops would be a good choice for my needs?

  • Acceptable sound quality: stereo needed for an Android game?

    - by Thomas Calc
    I have various simple short sound effects (damage sound, dying sound, thunderbolt, fanfare, breaking) for a game that is developed for Android currently. I use OGG files: 96kbps VBR, 44.1KHz, 2 channels (that means stereo, right?). I read the other stackexchange topics about "acceptable sound quality", but they're too general, address too many things. My experience is that even with 80kbps, my effects sound OK. But I tested it on a limited number of Android devices (including a Sony Ericsson Xperia Neo and a HTC Desire HD). My questions: For mobile phones and tablets, generally, what parameters are recommended? Won't my 80kbps sounds be bad on a newer device (such as a modern tablet)? I don't hear any difference between stereo and mono (2 channels vs. 1 channel, right?), is there any noticeable difference at all for mobile phones / tablets? (in terms of the player experience) May it worth it at all? I assume that stereo sounds take much more in memory (when they're decoded to PCM), despite of the fact that the compressed OGG size is practically the same. Reacting to Roy T.'s great comment: Actually, I couldn't measure the PCM size (Android decodes OGG internally), but I thought that stereo will take more space than mono when uncompressed After throwing out one of the WAV channels in Audacity, and re-exporting it: The new WAV file size is half than before The OGG file size is practically the same as before The sound effects and game music was recorded by my friend who is an experienced hobby musician/composer, but he knows little about computers & software so he just gave me some high-quality WAV files generated via his hardware.These were stereo, but if I check them in Audacity, both channels appear to be exactly the same.Can I consider them the same (= moving to mono), or might there be some unnoticeable differences to the human eye?

  • Suitability of ground fog using layered alpha quads?

    - by Nick Wiggill
    A layered approach would use a series of massive alpha-textured quads arranged parallel to the ground, intersecting all intervening terrain geometry, to provide the illusion of ground fog quite effectively from high up, looking down, and somewhat less effectively when inside the fog and looking toward the horizon (see image below). Alternatively, a shader-heavy approach would instead calculate density as function of view distance into the ground fog substrate, and output the fragment value based on that. Without having to performance-test each approach myself, I would like first to hear others' experiences (not speculation!) on what sort of performance impact the layered alpha texture approach is likely to have. I ask specifically due to the oft-cited impacts of overdraw (not sure how fill-rate bound your average desktop system is). A list of games using this approach, particularly older games, would be immensely useful: if this was viable on pre DX9/OpenGL2 hardware, it is likely to work fine for me. One big question is in regards to this sort of effect: (Image credit goes to Lume of lume.com) Notice how the vertical fog gradation is continuous / smooth. OTOH, using textured quad layers, I can only assume that layers would be mighty obvious when walking through them -- the more sparse they were, the more obvious this would be. This is in contrast to where fog planes are aligned to face the player every frame, where this coarseness would be much less obvious.

  • Using USB to Ethernet with Linux Ubuntu 12.04

    - by Sriram
    Being a newbie, Please excuse if the technical Jargon used is not an universally accepted one :) I have a particular device (say device A) whose USB2.0 driver is available from Linux community. Linux UBUNTU12.04 based PC is able to detect that device via the available driver. My requirement is to ensure that PC can exchange the command as well as data with the device A over TCP/IP packets (In other words, instead of just a USB Based driver, there should be a TCP/IP wrapper over the device USB driver and still does the same job as the USB driver was doing before) Bought an USB (Female) to RJ-45 adapter,connected Device A (male) USB to the USB Female end of the adapter and the Ethernet end connected to the router. PC also is connected to the same router so that both Device A and the PC have the IP address in the same subnet range. So the packets produced by the device A can be routed to the PC via some binding( not sure how I can achieve this, but conceptual idea) Here are the issues I can see as of now 1) USB to RJ-45 is just a hardware signal conversion and not a NIC in itself and hence no MAC/IP ADDRESS assigned. Can we bind a virtual NIC created in PC with this connector? 2) Any available USB TO IP command as well as data translation wrappers available? e.g. command for the device A on Ethernet converted to command for the device A on USB which is then acted upon the device as a command from the USB driver There is some missing link in my understanding and hence it would be of great help if you can bounce off some ideas on how I can take this forward so that Device A and PC exchange data over IP. Thanks and Regards, Sriram

  • Nvidia optimus and Steam (on 12.04)

    - by Seiryuu
    I've obtained a copy of the .deb for the Steam beta, but it was pretty disappointing to see that it simply doesn't run. Hardware - Dell XPS L502, with Nvidia Optimus I have bumblebee installed. Trying to run Steam with the Intel HD 3000 completely fails to start it. Message received Installing breakpad exception handler for appid(steam)/version(1352224866_client) followed by a crash with no other information provided. Trying to optirun steam runs the client, but as soon as it gets to the home screen, it says that the Nvidia drivers I am using are out of date (and Steam requires newer drivers to run). It's probably worth to note that it throws the same Installing breakpad... error when run with optirun, but it doesn't crash the client immediately. Any way to fix this? Also, is there a way of manually updating the drivers in bumblebee without breaking anything? Alternatively, is there a reliable way of completely disabling the Intel GPU (in order to use the Nvidia GPU exclusively)? Note: I am using Xmonad with gnome-fallback, if that makes a difference. However, when I tried everything mentioned with Unity (2d), everything was the same, so I guess it has nothing to do with the window manager in use.

  • xorg, nvidia, log-in all hosed - how can I completely reset graphics set-up/settings?

    - by Fred Hamilton
    I just did a fresh install of Mythbuntu 12.04.1 on my Intel MB with nVidia 9500GT graphics card. Hardware's been working great with 10.10 for about 2 years. Background: (optional - feel free to skip to question) I was trying to get my component video output to generate 720p, messing around with the nvidia drivers, and now the entire display system is hosed. I can SSH in and get a terminal. Depending on which nvidia package I install/remove, I get: Garbage on screen (after I "apt-get remove nvidia*") A low-res graphical log-in screen where I can log in as fred or guest. If I log in as fred, it displays some text mode status line then goes right back to the log-in screen. If I log in as guest, I actually get the full Ubuntu desktop, but I need to be able to log in as fred. Other times I get an error: "API mismatch: the NVIDIA kernel module has version 304.43, but this NVIDIA driver component has version 295.49." I've googled around, including trying this thread with the same error message, but to no effect. Question: How can I just reset x settings, drivers, everything display-related to the exact same way it was after a fresh install?

  • Dummy output after upgrade from 12.04 to 12.10, even though sound card is detected

    - by user115441
    So I just recently upgraded my system from Ubuntu 12.04 to 12.10. However, when I booted into 12.10 for the first time, no sound comes out of my speakers. I checked the sound settings and the Dummy Output was the only thing showing up. I used "hwinfo --sound" to check to see if my sound card was actually installed, and it was installed. hwinfo --sound hal.1: read hal dataprocess 2687: arguments to dbus_move_error() were incorrect, assertion "(dest) == NULL || !dbus_error_is_set ((dest))" failed in file ../../dbus/dbus-errors.c line 282. This is normally a bug in some application using the D-Bus library. libhal.c 3483 : Error unsubscribing to signals, error=The name org.freedesktop.Hal was not provided by any .service files 11: PCI 1b.0: 0403 Audio device [Created at pci.318] Unique ID: u1Nb._aiKlM91Nt0 SysFS ID: /devices/pci0000:00/0000:00:1b.0 SysFS BusID: 0000:00:1b.0 Hardware Class: sound Model: "Intel 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller" Vendor: pci 0x8086 "Intel Corporation" Device: pci 0x2668 "82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller" SubVendor: pci 0x107b "Gateway 2000" SubDevice: pci 0x4040 Revision: 0x04 Driver: "snd_hda_intel" Driver Modules: "snd_hda_intel" Memory Range: 0x50240000-0x50243fff (rw,non-prefetchable) IRQ: 44 (91 events) Module Alias: "pci:v00008086d00002668sv0000107Bsd00004040bc04sc03i00" Driver Info #0: Driver Status: snd_hda_intel is active Driver Activation Cmd: "modprobe snd_hda_intel" Config Status: cfg=new, avail=yes, need=no, active=unknown I'm not sure what to do here. The only time the sound will actually work is when I boot into my Windows partition and then reboot into Ubuntu. I mean I don't want to have to do that every time I want to use Ubuntu. I would really appreciate any help I can get on here.

  • Very slow write access to SSD disks on some Asus P8Z77 motherboards

    - by lenik
    I have Asus P8Z77-V LK motherboard, that ran Mint 13 (based on Ubuntu 12.04) just perfectly, but recently I've tried to install Mint 17 and noticed abysmal write performance. Write speed on SSD disk was about 1.5MB/sec, when it's supposed to be in 150-250MB/sec range. For write testing I've used dd if=/dev/zero of=/dev/sda bs=10M count=10 while booted up from LiveCD. I have also tested the read speed with hdparm -tT /dev/sda and got about 440MB/sec -- that's normal. I can tell, the read performance has not degraded at all and is not an issue here. Since I had a few different SSD disks and few motherboards, I've tested and tested and here are results: Asus P8H77 works fine with Mint13, has very slow write speed starting from Mint14. Asus P8Z77-V LK works with Mint13, has very slow write speed starting from Mint14. Asus P8Z77-V PRO works with Mint13, and works just fine with Mint14, 15, 16 and 17. The only difference between "PRO" version and others is that it has extra SATA controller onboard (in addition to the Z77 chipset SATA controller) providing extra 2 SATA ports. SSD disks work fine with "PRO" version when connected to the native SATA ports as well as to the ports provided by extra SATA controller, so this does not look like a hardware issue. As far as I can tell, there's something changed in the kernel while going from 3.2 to 3.5, that affects the detection of onboard SATA controller for Asus P8*77 motherboards, that screws up the write speed for SSD drives. Could anyone shed some light on how to fix this issue or, possibly, give a pointer to a more suitable place to ask this question?

  • Steam (via Wine) crashes after login - any troubleshooting tips?

    - by new Thrall
    The Steam client crashes after I login. After submitting my credentials, Steam displays a dialog box informing me the client is 'connecting'. I then see the Steam main page and news page displayed for roughly a second or so before the client crashes. I'm running Ubuntu 10.10 (I think..what's the best way to verify? uname only displays Linux) which I've installed on a usb flash drive using a capser-rw file for persistence. wine-1.3.14 I'm not sure how to troubleshoot. How do I identify if the problem is with wine or steam or the video card driver, or what?

  • IoT? Time for Enterprise Architecture

    - by OTN ArchBeat
    Of course you've been listening to the latest OTN ArchBeat Podcast on the challenges and opportunities in the Internet of Things. If so, you'll also be interested in ZDNet blogger Joe McKendricks' recent post, Will the 'Internet of Things' make CIOs' jobs harder?. In that post McKendrick offers this important bit of advice that will certainly have architects saying "I told you so." Enterprises need to develop architectural approaches to the management of data. Meaning the development of repeatable processes to source, ingest, transform and store information. For years, IT managers simply bought more hardware and addressed data with on-off integration projects. Now it's time for enterprise architecture. IoT is an important new phase in the evolution of enterprise IT. Challenging? You bet! But meeting any such challenge requires big, broad thinking and planning. In that context Enterprise Architecture has always been important. But as IoT gains traction and speed, enterprise architecture should be top of mind for all concerned.
