• Sound card stop responding

  - by Merianos Nikos

  A few days ago I installed the latest version of Ubuntu in a computer of mine, that it has installed the "Sound Blaster Audigy 2ZS". After the installation and up to yesterday everything was excelent. Yesterday I installed the latest Ubuntu updates and today I had several issues. First the mouse was not responed as should be, but after restarted my computer everything was fine with mouse. Next was my sound card. For now I do not have sound at all :( I don't really know what's wrong. Does anybody has any idea on how to solve that issue, or from where to start, to find a solution ? If there is no any available solution for that issue, can I remove the latest updates that installed yesterday ? Kind regards Merianos Nikos

• Mouse disables on key press, but touchpad doesn't

  - by Dan

  My mouse cursor disables for 1-2 seconds when the keyboard is used. This can make gaming especially difficult. The touchpad is fine; I can use it at the same time as the keyboard. Doing some forum searching, I can see that going to mouse and touchpad touchpad disable touchpad when typing works for the touchpad, but I still have the problem when using the mouse. I've tried using synaptiks, and setting the 'automatically switch off touchpad on keyboard activity' time to 0 seconds doesn't seem to work either. I'd appreciate any help.

• Getting the Dell XPS 16 Synaptics touchpad to work after hibernation

  - by Aron Rotteveel

  I am currently experimenting with using Ubuntu as a my main OS instead of Windows 7. So far, pretty much everything is working fine, except for an issue that I am having with my touchpad. I have a Dell XPS 16 (1640) with a Synaptics touchpad. It works out of the box, but it seems that it stops working after returning from hibernation mode. This problem has also been addressed in an earlier bug, but judging from this bugreport, it should be fixed by now. I am running the 2.6.35-23-generic-pae kernel. Any ideas?

• How to get disable nVidia Graphics Card (which has recently expired) so that I can boot Desktop ?

  - by shan23

  I have a 3-4 years old laptop (Compaq V3000), which had Win Vista with Ubuntu 10.10 in dual boot configuration. The graphics card inside is an old Nvidia GeForce Go 7200. One fine day, my graphics card died (of old age, presumably) - resulting in myself being initially unable to boot to WinVista and Ubuntu 10.10. I solved the problem with WinVista (disabled Nvidia card after booting to Safe mode), but I don't know how to do the same with Ubuntu. I can only disable the 3rd-party driver after I boot to desktop, but since its crashing before that, I'm unable to do so. Can anyone help me disable the graphics card in Ubunutu ?

• How to write a network game?

  - by TomWij

  Based on Why is so hard to develop a MMO?: Networked game development is not trivial; there are large obstacles to overcome in not only latency, but cheat prevention, state management and load balancing. If you're not experienced with writing a networked game, this is going to be a difficult learning exercise. I know the theory about sockets, servers, clients, protocols, connections and such things. Now I wonder how one can learn to write a network game: How to balance load problems? How to manage the game state? How to keep things synchronized? How to protect the communication and client from reverse engineering? How to work around latency problems? Which things should be computed local and which things on the server? ... Are there any good books, tutorials, sites, interesting articles or other questions regarding this? I'm looking for broad answers, but specific ones are fine too to learn the difference.

• PS2 keyboard scroll wheel doesn't show up on xev, how to make it work?

  - by ncomx

  I have a ps2 keyboard that has a scroll wheel on the side, it doesn't work on Ubuntu 12.04 so I though to just check xev and map the correct key. But xev doesn't show up anything when moving the scroll wheel. The keyboard is this one (A4Tech KBS-26), it works fine on Windows without adding any extra driver. On linux most buttons work, multimedia, calculator, browser, etc. The only thing that doesn't work is the scroll wheel and copy/paste/cut/undo buttons, and they don't show up on xev either. Does someone knows how to make it work?

• Ubuntu 13.10 not playing DVD videos

  - by John Hill

  I installed Ubuntu Gnome 13.10 on my computer yesterday, and everything seems to be working fine so far, except that it isn't reading video or audio CD's and DVD's. At first, I inserted a DVD video, and it played normally for maybe 30-45 seconds before coming up with a "internal read error" or something like that. I was using the Totem player when the problem occurred, so I tried installing the VLC media player. It wouldn't read the disc at all, so I uninstalled the player. Now, the Totem player won't even begin playing the DVD. The player sometimes doesn't even open up when I insert the DVD, and other times it will but says it can't read it. I've tried several different DVD's and CD's with similar results. The computer is recognizing the optical drive, because when I open "Files", it shows the drive and the disc, but can't play it. Previously, I ran Ubuntu 13.04 with the Gnome desktop installed from the software center, and I had no issues. Any help is appreciated!

• How to add a shortcut for Humble Bundle games in Unity?

  - by waspinator

  I downloaded some games from the humblebundle, but most of them don't have deb files. They run fine after extracting them and double clicking on the executable, but unity doesn't automatically find them so I can't search for them, or add them to the side bar. I tried to drag the executable onto the side bar, but it just dimmed and didn't do anything once I dropped it. I also tried to right-click on the executable in and clicked on "Make Link", but I couldn't drop that onto the side bar either. I would prefer a solution that does not require using the terminal or editing configuration files by hand if possible.

• Is it worth upgrading Ubuntu 10.04 to 12.04? [closed]

  - by Ariel

  A few years ago, I used Ubuntu 10.04, and i liked it a lot. It never crashed. Then I have to change to Win*** because of work. But this year, I heard about Ubuntu 12.04 and I wanted to install it. I've done this, but I have a lot of crashes. I don't do something special to make ubuntu crash, but sometimes it shows me a crash message. So, is it worth migrating to 12.04? Do somebody stay with the 10.04? I really want to use ubuntu, and I will, but I don't know if it worth to use the newest release or with the 10.04. If i install the 10.04 version, ubuntu tells me all the time to upgrade to the new version? Or will I use it fine? What do you suggest me? Thanks everybody for your time, and sorry for my english.

• LightView: JavaFX 2 real-time visualizer for GlassFish

  - by arungupta

  Adam Bien launched LightFish, a light-weight monitoring and visualization application for GlassFish. It comes with a introduction and a screencast to get you started. The tool provides monitoring information about threads and memory (such as heap size, thread count, peak thread count), transactions (commits and rollbacks), HTTP sessions, JDBC sessions, and even "paranormal activity". In a recently released first part of a tri-part article series at OTN, Adam explains how REST services can be exposed as bindable set of properties for JavaFX. The article titled "Enterprise side of JavaFX" shows how a practical combination of REST and JavaFX together. It explains how read-only and dynamic properties can be created. The fine-grained binding model allows clear separation of the view, presentation, and business logic. Read the first part here.

• Can I use Visual studio for Python and Django development?

  - by Pankaj Upadhyay

  I have been using Visual Studio for quite some time now, in fact from the VS 2005 version. Right now, I am not only comfortable but addict to using it(VS 2010) for all my development needs. Recently I have been learning Python and Django. In that getting the tutorial tasks up and running with IDLE seems very lame and outdated(I am following the Django Book). Therefore, I downloaded and configured Eclipse & PyDev. Eclipse seems good and fine but needs a bit of learning curve for itself. So, I am looking for a way to configure Visual Studio 2010 for Python and Django development if possible. Please tell me if that's possible and How ?

• Notifications not working in Gnome 3.4

  - by chazdg

  Notifications are no longer working in Gnome 3.4 but they are working in Unity. I have tried everything I can think of but I am stumped. To clarify, I am changing the theme using Gnome Tweak. Themes were obtained from various repositories including noobslab/themes and webupd8. As an example, when using the default theme adwaita, I get all notifications when using Rhythmbox as to what song is being played on an internet radio station. I even tried a different media player with the same result. When I change the theme, all I get is a media player Icon. Change back to default theme and all Notifications work fine. Notifications were working at first with all themes, but no longer. The question is how to get Notifications to work for all themes. They did for previous versions of Gnome-shell.

• glx not working, optirun works, gnome in fallback mode

  - by user26766

  It all started when I installed nvidia's own driver. Uninstalling it and reverting back to nvidia-current didn't solve the problem, so I have been playing with this for a while. Now nvidia-current seems to be functional. It seems glx support is missing, and my intel graphics is not responding. gnome loads only in fallback mode. Here are some outputs: glxinfo name of display: :0.0 Error: couldn't find RGB GLX visual or fbconfig glxgears Error: couldn't get an RGB, Double-buffered visual optirun glxgears works fine lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT 540M] (rev ff) how can I fix this? thanks,

• Auto_raise broken in GNOME 3.4.1?

  - by Alex Balashov

  Since dist-upgrading 12.04 LTS in such a manner as resulted in an upgrade of GNOME from 3.2.x to 3.4.1, auto_raise is broken. I have the usual auto_raise* settings set in gconf, in apps - metacity - general. But the functionality just doesn't work anymore. Focus follows mouse works fine, yes, but windows just no longer raise after a short delay. I have tried both gconf and tweak tool-based remedies, to no avail. Any ideas on how to work around this? Auto-raise is a really integral part of my workflow.

• Skype, add-on applications, UAC and "Unable to respond"

  - by Greg Low

  Just posting this blog tonight hoping it might save someone else a bunch of time. For call recording on Skype, I use a program called Pamela. Lately, when I'd first installed it, it would work fine. Later, however, it would come up and say: "Another application (Pamela.exe) is attempting to access Skype, but we are unable to respond". You just have to love these sorts of messages that don't give you the slightest clue about what the problem is. While I saw the problem with Pamela, it can happen with...(read more)

• Ubuntu doesn't find hdds with higher clock rates

  - by user136243

  I dual boot windows 7 64-bit and ubuntu 13.10 64-bit on separate disks, and utilize some overclocking from the BIOS. Windows works fine, however ubuntu can't seem to find any hard drives, except for at stock cpu speeds. While attempting to boot it says Gave up waiting for root device... and ALERT! /dev/sdb7 does not exist. Dropping to shell! A bootable usb stick still works, but gparted doesn't detect any other drives. Have tried: Boot-repair Changing SATA mode in BIOS Newer kernels Older ubuntu versions Not sure it's relevant, but the motherboard is a Gigabyte GA-A75M-UD2H with the newest BIOS version, the CPU an AMD Llano. This is hardly a fatal error, but it's inconvenient to change BIOS settings whenever I want to switch OS, and furthermore I'm quite curious about why it won't work. I'd appreciate any insight into what the actual problem is. So how can I resolve this issue ?

• How can I resize an external USB NTFS partition?

  - by chris

  I have a new USB drive which came with a single NTFS partition. How can I shrink that so that I can create an ext4 partition? gparted does not seem to have the "Resize" option highlighted. Update: After following the directions below, after unmounting I am still not able to resize the partition. There is a warning though: "Unable to find mount point. Unable to read the contents of this file system! Because of this, some operations may be unavailable. The following list of software packages is required for ntfs file system support: ntfsprogs". However, with the partition mounted, I can read & write to the file system on the drive just fine, and ntfsprogs is installed and current. What's next?

  - by Jerome

  I have a gateway m-1625 laptop. The specs are: 3gig DDR2 ram, amd turino*2 processor 2Ghz, 250gig HD, windows 7 ultimate. After installing unbuntu 11.10 and using it for about an hour my laptop starts shutting down most times before even reaching the log on screen. I have re installed it twice but the problem still persist. I had this same problem with ubuntu 11.04. I have been using ubuntu for the last 5 years and never had this problem before. Windows 7, vista and fedora runs fine, it just ubuntu that gives any sort of issue. What could be causing this problem? has something critical been changed since the 10.10 version? I really love ubuntu and i want to be able to run it again

• To mount NAS on a Laptop?

  - by deckoff

  So, I bought a NAS, which I configured successfully in /etc/fstab, on mu Kubuntu 10.10 Thinkpad x40. It works just fine when I am at home. A few days I went out with my laptop and the problem is, that when not at home, both suspend and hibernate functions seem forever to work. I commented out the entry on fstab and the laptop started to work as expected. I played with autofs, but it seems just dies at one moment and I cannot access anything. It works for some time, and then just goes off. Is there any consistent way, to make my laptop access the drive when at home and work OK when away? Probably a script that runs at startup, checks if the mount is there and mounts it if available... or a script that umount the drive at suspend|hibernate and loads it back at startup. Any useful ideas?

• Laptop not syncing with Ubuntu One

  - by Lolwhites

  I have a desktop running Maverick, and a laptop running Lucid. Both are supposed to be linked to my Ubuntu One account. The desktop syncs fine, but when I started the laptop for the first time in a couple of months, it wouldn't sync any more. The Ubuntu One Preferences window either reports "Synchronisation complete" even though no recent files have been downloaded nor have any test files created in the relevant synced folder been uploaded, or it says "Synchronisation in progress", which does not appear to be happening as it stays like this for ages and the lights on my router suggest no traffic is going through. Have repeatedly tried disconnecting and reconnecting, and removing the device from the account then reattaching it, all to no avail.
