• Regular wireless dropouts on new lenovo T440s in Ubuntu 14.04

  - by user290670

  Over the last 24 hours my wireless has dropped out regularly. I've tested to make sure it isn't my router (my phone and everyone in the house isn't having problems using the wifi). This is a brand-new installation of Ubuntu 14.04 and according to uname I'm running kernel 3.13.0-24-generic. Now, my laptop has an Intel 7260AC dual band wireless card and I've read that Ubuntu has been having trouble with these. I notice that at http://www.intel.com/support/wireless/wlan/sb/CS-034398.htm There are some updated drivers for my kernel version. However I have no idea how to update the kernel to use these drivers instead so that I can see if this will fix it. Can anyone help? These dropouts are really annoying. EDIT: Upgrading to 3.14.6 did not help.

• Cannot boot Win7 after updating to ubuntu 11.10

  - by angryInsomniac

  I had a dual boot setup on my system, with ubuntu 11.04 and Win7. Yesterday I updated ubuntu to 11.10. Now , I cannot seem to be able to load Win7 , I do see an entry for it on the boot menu. I select that entry and then the screen goes black , with everything coming to a standstill. I tried to wait for it to respond but nothing happened. I went through the forums and tried "grub-update" but when I do that , nothing really happens. I am not sure of this , but I get no output from grub for upto 10 minutes ( can grub-update be made verbose ) How can I fix this and get back to booting both OS'es properly ?

• Studying parallel programming

  - by mort

  I'm currently finishing my Bachelor's degree in Computer Science and thinking a lot about which specialisation to choose in my Master's degree. One subject I'm particularly interested in is parallel programming. However, this topic does not seem to be a standard topic in Computer Science degrees, although it is something that is used more and more - new processors nowadays are usually dual or quad cores. So I was wandering: does anybody know a good study program in this field? I was mostly looking for it at universities in Germany, but they tend to combine the application side with some type of engineering or natural science. Thus, programs are more the "Computational Engineering" or "Computational Science" type, but I'm more interested in the Computer Science part of it, i.e. parallel programming, languages and compilers, algorithms and hardware.

• How to ssh to my dorm computer with shared public IP and no admin rights over the router?

  - by Aamir

  First of all, I am not a Linux or ssh newbie. I have searched for this problem on many forums extensively but nobody seemed to have discussed this. Please help me! I live in a student dorm (off-campus) and all students of the dorm share the same WAN IP (Internet or public IP), which is fortunately static. I am not an admin and have no control over the router that assigns private IP's to all of the students, so I can't really forward port 22 to my computer :( Is it still possible to establish an ssh connection to my dorm computer from a computer on campus?

• Why does my wifi fail to stay connected?

  - by Mark0978

  We have 5 different laptops in the house, 1 macbook, 1 Compaq, 3 dells, plus numerous little devices like ipods, squeezeboxs, squeezebox radios and controllers, you name it. All of them connect to and stay connected to the "downstairs" WIFI just fine. But my laptop (the most expensive of the lot) refuses to stay connected, preferring the much weaker and slower signal upstairs. My laptop is running Win7 (64 bit) Ultimate with an Intel 3945ABG WIFI contoller (It's a Dell Precision M6300). The WIFI Access Point is a Cisco WRT54G2 V1 with firmware: Firmware: DD-WRT v24-sp2 (10/10/09) micro Time: 11:11:10 up 42 min, load average: 0.06, 0.01, 0.00 WAN: Disabled

• WUBI install not completing on Dell Latitude D600 using 10.04 and 10.10

  - by Dennis

  While trying to install a dual boot from LiveCD, WUBI seems to go through all the steps correctly. It unpacks everything, reboots, starts to finalize the install, brings up the install slide show and seems to do everything necessary. The slide show disappears and what is left is what would normally be the background, however there is no login, no panels, no response to any input or keystrokes. Using 10.04 I had a mouse cursor (working) with 10.10, not even that. In 10.04 The only way to reboot is to shutdown using the power switch. When it reboots it goes through the "finalizing install" phase again. In 10.10 if I hit the power switch it brings up a shutdown menu that doesn't respond to the keyboard, but does shutdown when the 60 seconds expire.

• Set up Java path for terminal

  - by Xsteen

  Trying to set up a path for the terminal. I already have Eclipse running great. Dual os between windows 7 and Ubuntu 12.04. However, I would prefer to run everything out of Ubuntu, just not very experienced and all the forums I have searched are not giving me the step by step answers I need to make this happen. I included a screen shot of some information about my version etc. Any help would be greatly appreciated at this point I've put 10+ hours into this and this is my last resort.

  I set up dual boot on my extra pc last night. first installed windows 7 and that went just fine. Downloaded Ubuntu and then did the MD5SUM and did not get a correct return that were listed on the site. I forgot to do that before I burnt the image to a disc. so I booted from the disc anyway to do the intergrity check and no errors were found. I then installed and everything seems fine except when it's booting, the purple screen is broken. should I try to redownload and re install?

• Not mounting/finding 1TB NTFS drive

  - by Dave

  I am having trouble with Ubuntu recognizing/finding/mounting one of my hard drives. I dual boot Ubuntu and Windows 7. I had Ubuntu 10.04 and all drives showed up under "Places" I could click on any of my Windows/NTFS drives and they would mount as they should. I have since updated to Ubuntu 10.10. One of my drives no longer shows up in "Places" or in Nautilus. I can open gparted and it is listed there, but if I try to click the mount button, I get an error. I am currently at work and can not post any screenshots or errors, but will happily do so later. I was just hoping that someone might be able to give me something to try when I get home. 250gig SATA hard drive (Windows7/NTFS) - recognized/mountable 200gig PATA hard drive (Ubuntu 10.10) - recognized (obviously) 1TB SATA hard drive (NTFS) - not recognized/won't mount Thanks!

• Cannot read from 2nd SATA data drive connected via SATA docking station

  - by Robbo

  Installed 10.10 this week on dual boot system. Everything else works fine but cannot read from 2nd SATA drive with all my data. Same drive works normally when booted to Windows XP. Interesting part is that I can see the drive in Ubuntu Disk Manager, can read all its attributes, can test it, shows up in Disk Manager, Storage Device Manager and Mount Manager, and can mount it, even change attributes; it appears healthy but does not show up in "Computer" or anywhere else that it can be accessed. The drive is connected via an external e-SATA docking station which is connected to a SATA port on the motherboard.

• No enable mobile broadband option

  - by noboot

  I just migrated from Wubi to actual dual booting Ubuntu and Windows 7 my machine is an Aspire 4750G. When I had (Wubi) Ubuntu 12.04 LTS 64-bit the network applet included the "enable mobile broadband" option. Now, I am using Ubuntu 12.04 LTS (32-bit) actual install as the 64-bit does not work. And my problem is that it does not show the "enable mobile broadband" option. This is so weird considering that I did not encounter the same problem in Wubi based installation.. Kindly help.. I have managed to connect to the internet via Sakis3G Script, still I find the previous method a lot more convenient..

• How can I stop Windows DNS server properties settings from changing by themselves?

  - by paradroid

  When I open the DNS console in Administrative tools, I keep finding a couple of problems which keep on reappearing by themselves, and I want to stop them from happening. One of the DNS servers has two network interfaces, and it should only be listening for requests on of them, and I get errors in the Event Log otherwise. But when right clicking one DNS server and selecting Properties, I can see on the Interfaces tab that 'All IP addresses' is selected. If I Change it to 'Only the following IP addresses:' and deleselect the WAN addess, I will find it reslected when I next check it after a couple of days. In the other DNS server's Properties, on the Forwarders tab, there should only be two forwarder addresses. However, the address for the router keeps in appearing. This router has the DNS server as its forwarder. There shouldn't be anything using the router's DNS forwarders for DNS other than the router itself, but this surely is causing a loop. How do I get these properties on both DNS servers to stick?

• Incorrect key mappings in remote NX session

  - by Roger Light

  I'm using the NoMachine provided NX client on Ubuntu 10.10 running on a laptop. I'm connecting to a FreeNX server that happens to be running on openSUSE. I'm having trouble with keys being incorrect in the remote session. The most noticable example is that when I press up cursor, the screen shot dialog appears instead. As far as I can gather easily, the cursor keys and delete are affected. It's worth noting that it doesn't display the same behaviour if I dual boot to Windows XP, or from a different machine using openSUSE. I'm not really sure where to begin looking. Any suggestions?

• If I release a program under GPL, do I have to continue to do so?

  - by Kos

  Consider this scenario: I am developing a program FooSuite that uses a GPL-licenced library QuuxTools I release the program FooSuite 1.0 under GPL Later on I discover that, for some reason, I need to licence the program to someone on different terms. Hence: I remove the dependency on GPL via QuuxTools, by either... rewriting the program not to use this library any longer obtaining a different licence for QuuxTools (if it's dual-licenced; see PyQt) I release FooSuite 1.1 under a non-GPL licence. However, FooSuite 1.1 is still a derivative work from FooSuite 1.0. I understand that it's not legal for a stranger to do what I did, but am I myself - as the owner of FooSuite - free from this restriction?

• Server 2008 R2 Datacenter (and all other version) not detecting hardware

  - by Mitchell Skurnik

  I upgraded my ASUS KFN32-D SLI/SAS motherboard to the latest BIOS version and swapped out the 2 dual-core procs with 2 quad core procs. After installing Server 2008 Datacenter onto the system I noticed that it was not connected to the network. I open device manager and see no network adapters. I have to go up to View - Show hidden devices to even see the virtual WAN Miniport adapters. This problem happens in Vista and Windows 7 (all x64). What is even stranger is it all works in x86 mode. What in x64 could be causing windows to not even detect hardware that works in x86? Is the boot manager possibly the culprit?

• Need to adjust touchpad edge scroll area

  - by MikeVB

  I have an Acer Aspire that I have dual booting XP and Ubuntu. On the Windows side, the driver allows you to set how close your finger has to be to the edge of the touchpad before it goes into scroll mode. In Ubuntu I don't have the option (at least in the GUI) to change the scroll area on the pad. Is there a conf file or other way to change this? I'm constantly getting into the scroll area during normal usage. I would like to leave it on without losing so much pad area to the scroll feature. Thanks a lot.

• Setting up wifi router as a switch for Internet Connection Sharing

  - by William C

  Can my laptop with a 3G connection share its Internet via a Wifi router (Dlink DIR-615)? I turned Internet Connection Sharing on and Windows assigned 192.168.137.1 to my laptop's LAN adapter. Do I connect my laptop to the WAN port or to the LAN port of the router? What should I set as my router's IP address? Do I turn DHCP on my router on? Do I assign 192.168.137.x as static addresses on the other computers? If not, what? Is there anything else I need to set on my router? Thank you!
