• Laptop Regret

  - by Richard Jones

  Just a casual observation. To base line this. I've discussed this one terrible horror in the past, 'hot bag syndrome'. This is when you realise that you've just travelled home with your laptop enclosed in its carry case without it properly powering down. So new one today, 'Laptop Regret' You pull out your laptop and power it up connected to (boss in room) projector demo to reveal your previous nights Spotify dance music party mix / stroke / eclectic mix of website surfing (make what you will) collection. Its a social phenomena, it happens (not to me obviously), but I'd just like to benchmark my findings. (OK, it did happen to me)

• Backtrack 5 R2 Dual-Boot w/Windows 7 No Longer Loads

  - by dstars5

  A while back, I installed Backtrack 5 R2 to Dual Boot on a Windows 7 PC. It worked fine for a while, but now when I try to load it, the screen gets all messed up (tried to get a picture with my phone, but it wasn't working too well). The last line before it freezes says: fb: conflicting fb hw usage: nouveaufb vs VESA VGA - removing generic driver Since it last worked, the only changes I can think of are that the computer is now connected via ethernet cable to the router, and I upgraded the graphics card (to nvidia). Because of the last line, I personally would put my money on the latter, but I still have no clue how to fix this. Can someone help me? Thanks!

• 12.04 drops Wired Network if Wireless connects

  - by mitt10tim

  This is a little different then most of the questions I have seen here. When I am at my office I keep my Lenovo Thinkpad t61p running Ubuntu 12.04 x64 connected via wired Ethernet. I also typically leave the wireless radios on. After a recent update the behavior of laptop in regards to the networks has changed. It used to be that if the laptop had a wired connection, the wired would supersede the wireless. Now, when I get to work and plug the laptop in and power it up, it connects via wired (correct behavior), shortly after the wireless begins searching for its favorite network (also correct) but as soon as it finds a network to connect to, I lose Internet. If I disconnect from the wireless network, leaving the wireless radios powered on, and refresh the wired connection, all is well again. Powering down the wireless radios also corrects the problem. How can I set this up so that the wired network (if available) always has precedence over the wireless?

• USB printer doesn't finish in 12.04

  - by 213441265152351

  I have an HP Deskjet 720C connected through a USB cable to an Ubuntu 12.04 laptop. When I plugged the printer for the first time into the fresh 12.04 laptop install, it auto-detected the printer correctly and choose the recommended drivers without a problem. The document print fine until they reach the end of the page, then suddenly stop just about the end leaving the page unfinished. I have checked that the margins are the correct ones. I have the latest version of cups installed. I have also tried changing the options of usb-unidir-default and usb-no-reattach-default via lpadmin, but the printing stops even earlier. Any ideas?

• Bluetooth broadcasting realtime - is it possible

  - by user69961

  Is it possible to broadcast data via bluetooth to one ore more connected devices? I mean that each phone will be master and slave at the same time and each phone will broadcast data that should be received by all other phones. Or is the only possibility to use a "client-server"-like topology; one phone acts as a server and listens to all clients and then sends data from each client to the rest of clients in the network? Which variant should be more effective? If broadcasting is possible then the same implementation can be used for all devices and if one device will die communication between rest of network can continue. And also will there be enough to send one message per device - not message from each device to server and then back to all devices. Am I right?

• How to setup VPN as Proxy

  - by Nicolas Nox

  I have an PerfectPrivacy VPN connected via the OpenVPN-Network-Manger-Plugin (Ubuntu 12.04.1) and I want to assign a system wide proxy over that VPN. I have tried proxydriver that should do that automatically, but it works partially. The browser says that I have the IP of the VPN, but when I tried to send an eMail over SMTP (Port 25), I can´t connect to the mail server. In our company the smtp server port is closed, but that should be not a problem, when I do that over a VPN, shouldn´t it? greetings

• Wifi works perfectly on Windows, but drops on Ubuntu

  - by alecRN

  I have a dual-boot computer with Windows XP on one partition and Ubuntu 10.10 on the other. In Windows XP I can connect to a hidden wireless network (WPA-PSK AES) perfectly, and I was finally able to install the driver for the adapter on Ubuntu (RNX-N180UBE, hardware id RTL8191SU). It works fine when I first boot the computer and log in, but then after a few minutes the network suddenly stops working completely. If I try to reconnect it, the network manager claims to have connected, but in actuality it's still down. At some points, I have been able to connect to a public network even while the private network didn't work, but that eventually wouldn't work at all either.

• How can I change resolution of "my video" in Skype?

  - by koushik

  I have a logitech Quickcam Pro 9000 connected to my ubuntu desktop and it works fine with Skype. However, Skype inputs and sends my video at the native (for the webcam I think) resolution of 1600 x 1200. I can confirm that the camera supports a wide variety of resolutions starting from 160 x 120 upto 1600 x 1200 (including e.g., 320 x 240, 352 x 288) using cheese. I can select these resolutions and see the output is appropriately scaled. Also, I don't see any improvements in smoothness of motion in the captured video so I suspect the original 1600 x 1200 is scaled down in the path somewhere. Is it possible to somehow to enable this scaling capability towards Skype?

• Problem with the screen resolution on 12.04

  - by sveinn

  I just installed Ubuntu on my laptop. The screen resolution is stuck in 1024x768. The screen is made for 1280x800. When I run xrandr I get: xrandr: Failed to get size of gamma for output default Screen 0: minimum 800 x 600, current 1024 x 768, maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm 1024x768 61.0* 800x600 61.0 1280x800 isn't offered and I get gamma size error. I was going to look into the Xorg.conf file but I couldn't locate it. 1280x800 was displayed in Windows 7 and I think it is being displayed in Grub before Ubuntu starts also. Here are some details about my computer: CPU: Intel atom D2500 1.86GHz Chipset: Intel 945GSE+ICH7M LCD: 14" TFT 16:9 Resolution ratio: 1280*800 Video Card: Intel integrated GMA950 Does anyone know how to fix this?

• Tools to diagnose Ubuntu problems

  - by Luis Alvarado

  Over time a user will have several problems with Ubuntu as any other OS in the world. What tools and terminal commands exist in Ubuntu to help diagnose how the problem occurred and help solve it if it can be done. Problems like: Ubuntu Freezes after X time or when using Y app Ubuntu rebooted/hibernated/suspended all by itself Ubuntu not showing video or video has problems Ubuntu not making any sound or sound has problems Ubuntu not reading X drive (Pen drive, Internal Drive, External Drive...)

• Broadcasting webinars to and from Ubuntu

  - by Chris Wilson

  I've recently attended an online workshop using Citrix GoToWebinar, a service that allows someone to broadcast their desktop and audio out to all members connected to the presentation as well as receive audio and screencasts from those attendees , and the experience was unbelievable, and I was wondering if there was any such service/software available on Ubuntu. Points to consider include, but are not limited to: Web services or local applications. Free (as in beer) or paid. Free (as in speech) or proprietary. Ease of use Ease of setup Any other point that anyone can thing of

• How do I add pcie_aspm=force to my boot options?

  - by nargo7

  I just upgraded to 11.10 from 11.04 on my laptop (I don't have Windows) by downloading from the Ubuntu website. The laptop battery is in bad condition, but I was using it with the 11.04 plugged to AC all the time, and everything was fine. After installing 11.10, the laptop seems to not notice that it is connected to AC, so it shuts down a few minutes after starting. I read that I have to type pcie_aspm=force in the boot command, so I tried accessing it by pressing the "F6" key while booting, and then the other F keys, but nothing happened. I also found that I can write that instruction in the terminal window, but I don't know in which file or location. I would appreciate some help, but I am not a computer engineer, so please write the instructions in plain English.

• Only sdb shows up when installing 12.04 on new Dell inspiron 14z

  - by Jan Korpegård

  I got my brand new Dell Inspiron 14z yesterday, but failed to install Ubuntu. I can boot from a USB stick, and it works well. When trying to install, I confirm that the laptop is connected to the internet etc (as in the 2nd picture in the installation guide: How do I install Ubuntu?). When pressing "Continue" I do not get the question on installation type (alongside/replace/something else). Instead I get a window where I can select partitions: // Picture removed due to low reputation... The problem is that I can only select sdb in the drop drop down box, and I can do do nothing with sdb (like adding partitions etc). The main disk (sda) is partitioned using Gparted the following way: // Picture removed due to low reputation As far as I understand from other threads on askubuntu, this should work... What can I do to install Ubuntu alongside with Windows 7?

• Best strategy to discover a web service in a local network?

  - by Ucodia

  I am currently doing some research for a project. The setup is simple, I have a computer running a service in my home network and any device connected to that same network should be able to discover the service automatically and use it. I have no specific technology requirement whether it is on the server or client side. The client knows about the service definition. Other than that I have no idea what strategy to use, what technology to look at or whether I should go for a SOAP or a HTTP based service. I think going HTTP with REST API is the best for targeting all devices but I am opened to any suggestions. Thanks.

• Connection timed out when connecting to a website (ubuntu only)

  - by S.C.

  I've been struggling with these problem for months. It happens randomly and it happens on Ubuntu only (12.04). It's about my hosted company website. Some facts: I can ping it I can traceroute it I can dig it I can make a nslookup But whenever I try to open it in Chrome it won't open. I also tried using polipo but got same connection time out issue. I'm connected through a LAN network and I'm experiencing no problem with any other website. Is there a more accurate debugging technique I'm missing other than pinging/tracerouting, etc.?

• How do I install on an Acer Aspire M3970?

  - by KillingJoke

  I cannot install Ubuntu 11.04 or 11.10 32 or 64 bit from CD or USB Drive on my machine. I tried to unplug all devices connected to USB, no changes the same thing: [ 15.383691] sd 7:0:0:3: [sdg] Attached SCSI removeable disk. And then the installation or Live image booting does nothing more... Its quite annoying that Ubuntu run on every of my Machines but not on my new PC :( What can I do to get that running? Edit: Fascinating thing I found out, is that the 10.04 LTS seems to work in every way. Why does 11.04 or 11.10 does not... Maybe theres a Bug in the installer ?

• Wireless doesn't connect in Ubuntu 10.04 Lxde

  - by David

  Problem I have a Dell mini 9, and the wireless has worked without trouble in Ubuntu and Xubuntu versions 8.04 and 10.04. However, after installing lxde, the wireless doesnt connect. Network manager recognizes the local networks, and will say that it is connected, but ifconfig does not confirm the connection or the existance of a wlan0. I have another Ubuntu 10.04 notebook that works fine. My wireless device is Broadcom BCM4312 802.11b/g What I have tried I have tried to remove and install network-mananager and inxi but neither work, and sudo modprobe wl returns WARNING: All config files need .conf: /etc/modprobe.d/blacklist, it will be ignored in a future release.

• MacMini (running Ubuntu 14.04) loses wlan connection when uploading larger files (several 100 mb) via ownCloud

  - by ManekenT

  I installed Ubuntu 14.04 on an old MacMini with the intention of running it as a homeserver. Additionally I installed ownCloud and tried to sync some files both from a laptop running elementaryOS and a desktop running windows 7. Syncing smaller files workes like a charm (4000 files at <10mb each) but when it comes to bigger files (1 GB ubuntu iso e.g.) the upload failes after 20-100mb. I can't ping the server anymore and the server can't ping me. It still shows up in our router as connected though. Disconnecting and reconnecting the wlan connection fixes the issue until the next attempt at syncing. Edit: I also had to install the wlan driver with this manual: https://help.ubuntu.com/community/MacBookPro8-2#Wireless

• Ubuntu 12.04 Battery problem

  - by Rahul

  I have my laptop ( Dell Inspiron 14R) on dual boot with Ubuntu 12.04 and Windows 7. While using Windows 7, I used to get about 2.5-3 hours on battery fully charged (with my cellphone connected for 3g Internet). The battery is almost 2 years old. But in Ubuntu 12.04, I'm getting only about 1-1.5 hrs on battery. I tried installing jupiter, also tried some tweaks that were mentioned in the forums, like editing the grub file. But nothing seems to work. I am not sure if any app is draining the battery. The one application that I use always is firefox. It's always open. Is there any way I could get at least 2.5 hrs of battery time?

• Remote Desktop between Ubuntu Machines

  - by user19192

  My desktop and my laptop are connected to the same router. I want to be able to remote login from my laptop to my desktop. Laptop is 12.04 and desktop is 12.10. I tried putting xrdp on my desktop, but remmina wouldn't work with it. I also tried the default screen-sharing, but it was very slow. Also tried rdesktop but it was very slow. I am on 12.10, FreeNX looks like a good option but they don't have a 12.10 release. And when I tried to install the 12.04 release, I got errors about dependencies missing. How can I get local-feeling remote login speeds?
