Ubuntu :: Jnlp Application Suddenly Stopped Working In 11.04

Aug 18, 2011

I use a small application called bendometer.jnlp. On my desktop running 10.04 it runs fine after opening with "OpenJDK Java 6 Web Start".

I have installed the same application on my brand new laptop running Ubuntu 11.04 and it was running perfectly until yesterday. Yesterday it hung during the startup and since I killed the hung process it has refused to start again. If I now run it in a terminal using the command

Code:
javaws "/home/steve/Music/Bendo/bendometer.jnlp"
I get the following errors
Code:
Unable to use Firefox's proxy settings. Using "DIRECT" as proxy type.

Ubuntu Networking :: Wireless Suddenly Stopped Working AND Rfkill Command Not Working

Jul 13, 2011

When originally installing 11.04 I had problems getting my Ralink 5390 wireless card to work.

Today my computer froze completely and I had to turn it off via the power switch. When I turned it back on, wireless was no longer recognized! My iPod can connect to the network just fine, so it must be an Ubuntu problem. There are no problems with my ethernet connection either.

I researched this and found several threads about blocking and unblocking wireless devices using the rfkill command. Well, unfortunately for me the rfkill command doesn't work. When I type sudo rfkill list or sudo rfkill unblock all, nothing happens; it just returns me to my bash prompt. I even tried uninstalling and reinstalling rfkill...nothing.

Ubuntu :: LAN Suddenly Stopped Working, Wireless Still OK?

Nov 19, 2010

A couple days ago I booted up my Ubuntu 10.10 machine as usual,but the wired LAN connection did not work; it doesn't seem to see any wired connection devices. I can still connect to a wireless network with no problem, and if I plug that same ethernetable into another machine it works fine. I've been happily using this setup for weeks; the LAN only stopped working a day or two ago. So I figure there's two possibilities:A recent update caused NetworkManager to stop working with wired LAN connections, but I'm e only persothed affected (unlikely)My motherboard's ethernet port died (this motherboard only a couple weeks old, so this also seems unlikely)I'm not good at diagnosing problems with networking, so who can tell me where to st

Ubuntu :: Unity Suddenly Stopped Working?

May 13, 2011

I have no idea what happened. When I restarted my laptop a message telling me that my hardware cannot support Unity came up. This is quite impossible, because I've been running Unity with no problems since 11.04 was released.

Compiz says that the interface is unity, and when I checked in login screen, it's not set to Ubuntu Classic or anything, just Ubuntu.

Ubuntu :: 11.04- Wifi Suddenly Stopped Working?

May 23, 2011

I have an asus EEE 1015N. Everything worked fine yesterday. I packed my computer, and went back home. After turning it back on, not only it didn't connect to the wifi network, but it did not even detect it. I know it's not broken or anything like that because when I boot into windows it works fine.I've been trying every solutionven in the "sudden wifi problems" threads in the forum (including checking the wifi power button, and trying to manually assign an access point to it), but to no avail.

Networking :: VNC To Ubuntu 10.10 Suddenly Stopped Working?

Oct 13, 2010

I've started to set up a server at my house, where I eventually want to run it headless, and I can just VNC in from my other Desktop. I installed Ubuntu 10.10, setup remote desktop on the server, and from there was able to do any work remotely. That was nice. I turn the computer off at night, and the next day when I was going to work on it, I cannot VNC in anymore. One day passed, and now every time I try to use VNC it comes up with "Failed to connect to server" I also set a static IP address on the server too, so I know the address isn't changing every so often.

Ubuntu Networking :: Wireless Suddenly Stopped Working?

Jul 24, 2010

I'm using Ubuntu 10.04. I was happily connected to internet and surfing some forum, when wireless connection suddenly stopped working.

Now I can't find any access point, and I'm pretty sure I didn't do anything to justify this behaviour.

It already happened a month ago, but I had to format my drive, so I didn't really bother to try to solve the problem.

Anyway. I'm posting here the results of the commands I think I can help with a diagnosis; if something else is needed.

I'm using a different computer to post this thread, so I'm manually writing the output.

Code:
sudo iwconfig wlan0
wlan 0 IEEE 802.11bg ESSID: off/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off

Ubuntu Networking :: Ethernet Just Stopped Working Suddenly?

Aug 12, 2010

Version: Ubuntu 10.04 Relavant hardware: P5QL Pro built-in ethernet, cable modem with linksys wireless-G router (although problem is with ethernet connection, not wireless)

One minute my ethernet was working, and the next it stopped working. The only thing that I did between it working and not working was install electricsheep from Synaptic and then I shut down the computer. When I restarted a bit later, no ethernet connection shows up.

I checked the cables, made sure they are in tight.

My laptop connects using the same ethernet cable fine. So its not the cable or the router.

I reset the router and the computer at the same time. Still doesn't work.

I don't know where to even start with troubleshooting this sort of problem. Everything to the extent of my computer knowledge seems to be working fine.

Ubuntu Multimedia :: Audio Suddenly Stopped Working?

Oct 24, 2010

I can't get any sound from either online audio or from a CD in drive. I've watched videos with sound with only occasional problems until today. I have been using MPlayer with internal audio 1 output - analog stereo output. When I start a vid, it will begin to D/L and play, but without sound. When I try to check the volume level everything pauses and then my system freezes. Sometimes it will release in a few seconds, but mostly it won't allow me to close Firefox and if I try to close the tab or window or Firefox, I have to reboot. Sometimes the vid will D/L without a problem, but no audio on playback. Oddly, when I bring up the system monitor, processors will show 1 or 2 cores stuck at 100% while the others fluctuate wildly. Download speed falls to almost nothing with occasional blips or nothing. I checked several sites and they all have the same problem. I have checked my physical connections, and bios settings.

There is an option for a RS780 Azalia controller 1 output Digital Stereo (HDMI) output, but I have not been able to make it work since the system was new. I don't know why.

This is the most recent SYSLOG file. The pulse audio errors have always been there, but since it didn't seem to affect playback, I didn't run it down.

Ubuntu Multimedia :: Sound Suddenly Just Stopped Working ?

Jan 5, 2011

I'm using Ubuntu and my sound was working fine and then suddenly it just stopped working.

It does however, have odd spells where its working (for like 2 minutes) but those spells are few and far between. So basically the sound is not working.

When it isn't working my speaker seem to be making these hissing/screeching noises.

I've tried looking up on Google on how to fix it, i.e. running terminals, etc. but still haven't come round to fixing it. Could someone explain to me how to fix the sound please?

And no, the speakers aren't on mute. I checked volume control and everything is full.

Summary:
Laptop: Acer
OS: Ubuntu 9.something
Sound card: hda-intel
Problem: Sound not working

Ubuntu Networking :: 10.04 - Wireless Suddenly Stopped Working

Apr 18, 2011

I'm running a gateway lapbook w/10.04 LTS and an etheros wirless card. Card has been working fine for almost a year - from cold boot, warm boot, and recovery from standy (shut lid, open, press power button). I was fiddling with setting a static IP for the wirelss card by modifying the interfaces text file. I made some changes, and restored the file to its original contents after some noodling around. Wireless still worked fine after that. Last night I took the laptop out of suspend as usual - lifted lid, pressed power button - but the wireless indicator remained grayed out and I haven't been able to reenable wireless connectivity since. ifconfig shows the wireless card is there, and cabling the e-net port directly to my hub works fine.

Ubuntu :: Udev Rules Suddenly Stopped Working In 9.10?

Aug 10, 2010

Recently I had made some udev rules to communicate with a few devices using USB ports. For some odd reason, they suddenly stopped working. Here are my rules:

Code:

ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", SYMLINK="HCS12"
ATTRS{idVendor}=="067b", ATTRS{idProduct}=="2303", SYMLINK="Driver12"
ATTRS{idVendor}=="050d", ATTRS{idProduct}=="0109", SYMLINK="Driver34"

According to the documentation, all that is needed to write proper rules is one match operator (relevant info) and one assignment operator (name of port). I am running kernel 2.6.31-22, so udev rules are valid for use (they require at least 2.6.15). My only guess is to include something that identifies the serial port.

General :: Wpa Supplicant Suddenly Stopped Working

Mar 16, 2010

Recently my wireless stopped working on my Debian testing system. It just doesn't connect. The best I get (only after a reboot) is that it says it did connect, but failed to get IP address. But usually it just tries to connect, disconnects straight away, connects again etc. so it never manages to associate correctly.

I am sure it did work about a month ago, stopped working after recent upgrades from the repository.

Ubuntu Networking :: Connection Failed And Suddenly Stopped Working

Jul 4, 2010

I installed Ubuntu 10.4 side by side with my Vista. This is on a PC I leave on permanently and use as a sort of Sever, so Security and Network connection are VERY important on this device. I use it for documents and IP PBX (telephone system). I currently use Vista and 3CX, but I plan to roll it over to Unbuntu full time once its up and runnng correctly - I will just need to change the Grub2 conf priority. After install, all was fine and I managed to make many changes to settings, apps and updates, but I have noticed in the past week when going in to make further changes the network has suddenly stopped working! According to Network Manager and the icon on the panel it is connected and I can not see anything obvious that is not correct. I tried doing a PING (192.168.1.1) from Network Manager to the main router, but it failed. I know that there is nothing wrong with the network nor the card or PC it all sits on. It's working now with Vista and my other machines. It must be a config some-where.

Ubuntu :: Autofs Has Suddenly Stopped Working - Finding Source ?

May 23, 2011

After several days of searching, reading and re-installing, I'm at a complete loss as to why autofs has suddenly stopped working.

Basically, I can see the shared folders on the host computer but as soon as I try to cd into the folders I get "-bash: cd: [directory]: No such file or directory" (where [directory] = shared drive.

The setup used to work and the exact same setup on another computer computer works flawlessly.

I'm running Ubuntu 11.04

Here is the content of auto.cifs:

Code:

Here is the content of auto.master

Code:

And credentials are stored in /etc/auto.smb.goblin (where goblin = name of windows computer sharing folders.

When I do "ls -l /home/shoryuken/TerraDrive/goblin" I get:

Code:

Now if I try to "cd" into any of the shared drives (like D-Drive, GW_Share or TerraDrive) I get the following:

Code:

A second or subsequent attempt at "ls -l" results in:

Code:

Note the question marks that are now everywhere.

I'm not sure where to look to find out why this is failing. The shared drive are visible, but then disappear when I try to access them. The same exact setup, on another machine works perfectly fine.

Fedora Hardware :: F13: UVC Camera Suddenly Stopped Working?

Jun 11, 2010

Finally got around to dual-booting and all was going well. I was surprised to see that the webcam on my Vaio worked straight away. However, some time between one boot and another the webcam mysteriously stopped working..

Here is the last time it worked:

Jun 6 23:12:51 dillinga kernel: uvcvideo: Found UVC 1.00 device <unnamed> (05ca:1837)
Jun 6 23:12:51 dillinga kernel: input: UVC Camera (05ca:1837) as /devices/pci0000:00/0000:00:1a.7/usb1/1-2/1-2:1.0/input/input12

Then the next boot:

Jun 6 23:41:48 dillinga kernel: uvcvideo: Found UVC 1.00 device <unnamed> (05ca:1837)
Jun 6 23:41:48 dillinga kernel: uvcvideo: UVC non compliance - GET_DEF(PROBE) not supported. Enabling workaround.
Jun 6 23:41:48 dillinga kernel: uvcvideo: Failed to query (129) UVC probe control : -32 (exp. 26).

[code]....

So I decided to boot into windows and make sure all was OK - and it was. Then I came back into Fedora and suddenly the camera was working again! I thought I'd reboot just to see if anything changed and alas here I am again with no webcam and the same error.

Programming :: SDL - Suddenly Music Functionality Stopped Working?

May 15, 2011

The problem started with that I got a lot of errors about missing header files included from SDL_mixer.h when I attempted to compile my projects. I looked in the directory of this file, and all header files were missing except SDL_mixer.h Resolved this by compiling and installing the base SDL library package. Programs that got recompiled and were able to play music before suddenly produced no music, but sound effects worked. However, old binaries that were compiled prior to the issue with the missing header files played music fine. What the heck is this? I get no errors, nor warnings; none at compilation, none on execution. The kernel pool (dmesg) is clean. There is also another strange issue, which perhaps has nothing to do with the first issue. x86_1$ ./fire XDM authorization key matches an existing client!Couldn't initialize SDL: Couldn't open X11 display.

Ubuntu :: Keyboard Has Suddenly Stopped Working In Gnome - Mouse Still Works

Jun 16, 2010

My keyboard has suddenly stopped working in Gnome (Ubuntu 10.4 LTS, Toshiba satellite laptop, P300). It works fine to logon, and with KDE.

The last thing I did before it stopped working was to hold down a shift key for too long, while I was thinking about what I wanted to do. The 'sticky keys' prompt popped up, which I killed. After that the keyboard has died - in *all* applications (e.g. gedit, terminal etc.)

The mouse still works. If I logout of Gnome, it comes alive again to type in the logon password. I had a look in messages, but without any enlightenment.

Ubuntu Networking :: Wireless Worked Before Update But Suddenly Stopped Working

Oct 14, 2010

I have an HP a670y desktop computer using the included wireless antenna (looks like a big Sorry game piece). I am running Ubuntu 10.04 x64 dual booted with Windows Vista x64. I haven't had internet for a while but just got it today and decided to do some updating in both Windows and Ubuntu. It had detected my router and I copied and pasted the WEP key then it asked for my password, but my keyboard wasn't connected so I clicked cancel for the password window and it connected anyway.

I opened the Synaptic package manager and started downloading some updates while I did some browsing on the internet. I had restarted my computer when the updates were done and it asked again for my WEP key. I copied and pasted just as I did before and entered my password and after it tried to connect it asked for my password again. I thought maybe the internet was down so I decided to boot up Windows and it connected right away. I wonder if one of my updates messed something up. Has anyone else had this happen?

Ubuntu Networking :: Network Manager Or Router Suddenly Stopped Working

Nov 25, 2010

Right so yesterday my internet worked fine. Today - no connection at all. The light for my cable on the router doesn't even show up. I originally had indicator-network installed, so when the internet first stopped working, I tried a few other options such as tethering to my phone via usb and bluetooth (which I have successfully used in the past). However, these didn't work, and I figured that as connman is still in beta, maybe that was why. So I reinstalled network-manager and network-manager-gnome via a usb stick, uninstalled indicator-network, and rebooted the computer. Still no internet.

When I click on the applet, it says "No network devices are available". This is odd, as I definitely have a network device... it is part of the motherboard. So I thought I'd do the SMARTlan test or whatever it's called. It's part of my BIOS, so I ran that and it returned results that I (kinda) expected: when the cable wasn't plugged in, it returned one set of results. When it was only plugged into my computer (and not the router), it returned another set of results. And when it was plugged into both my computer and the router, it returned a third set of results. So that leads me to believe the cable itself is fine.

And when I move the cable to a different port on the router, nothing changes. The corresponding light still doesn't come on. Network-manager, telling there are no network devices. The BIOS can see the ethernet port and the cable. And the router is functioning perfectly for my parents' computer and my ps3. And I have checked the cable to my computer for physical damage - it follows the same path as the one to my ps3, and on top of that, nothing physical can possibly have happened to it in the last day. This happened once before, except I don't think the network devices were lost.
