• replacing Zorin OS 8 with ubuntu 14.04

  - by Paul John

  I was trying to replace Zorin OS 8 with ubuntu 14.04 (32 bits). What I have tried: I took an empty pen drive and downloaded Ubuntu 14.04 iso file on to this pen drive. I then restarted my laptop (Lenovo N 3000) and pressed F12 I then selected the USB drive in the boot options. After sometime I got the Zorin flash screen again. I know I am "fundamentally" wrong in the manner how I am executing this installation process. If you could please provide me a stepwise instruction.

• Noisy audio recording in Ubuntu Linux

  - by Haresh K Miriyala

  I'm unable to record audio without noise on my Ubuntu laptop . It is not a grounding problem . My windows os is able to record voice without the static noise so, my hardware is fine . I read in the Windows forums that the os has software noise filtering mechanism that's automatically enabled. How do I do the same in Ubuntu? If not, please let me know how to filter the static noise. Any help is appreciated. Thanks!

• Failed to load session "ubuntu"

  - by harsh

  I installed CCSM to enable window previews in Unity. But when I went into extras, there was no 'window preview' option. So I tried experimenting with other options in Compiz and now there are no borders in the dialogue boxes (close, minimize, restore buttons are not there, I had enabled some 'flat....' option in Compiz. Later, I uninstalled Compiz and then reinstalled it. Now it says "Failed to load session Ubuntu" I can't even access through the guest account, I am new to Ubuntu.(please explain in detail). All I have access to is the login screen (it still shows my custom wallpaper). Please help, I don't want to lose my stuff.

• Which OS should I chose for my VPS?

  - by Camran

  I am about to order a virtual private server now, and have no experience in any Linux OS whatsoever. I am a fast learner however... My VPS provider provides these OS: Ubuntu 8.04 LTS Ubuntu 8.04 LTS 64-bit Ubuntu 9.10 Ubuntu 9.10 64-bit Debian 5.0 Gentoo Gentoo 64-bit Ubuntu 8.04 LTS + Ruby on rails I don't know what these are, however I have heard about Ubuntu alot, and know there is alot of information about it on the Internet. Will it make any difference which one I chose? I plan on running a classifieds website, which uses PHP, MySql, Java (for Solr) and the usual standard stuff (HTML, javascript...). Which should I chose? And what is the next step after chosing one? Thanks

• Sound coming out of headphone when running Ubuntu, but not window 7

  - by MrSimon

  I've downloaded Ubuntu yesterday, and I thought that everything went smoothly, until I found out a problem today. When I am running the Ubuntu OS on my laptop, the Samsung RC420, the speaker and the headphone works fine. However, when I am running the Window 7 OS, the speaker works fine, but my headphone will not emit any sound although the laptop has detected that 'a device has been plugged into the audio jack'. The same problem persist when I connect my X-minis as well. I tried updating my sound card drivers, check if they are hidden/disabled/disconnected and everything else. Nothing works :(

• 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!

• The best AutoCAD 2010 Ubuntu alternative?

  - by onvas

  I'm looking for the best AutoCAD 2010 alternative for Ubuntu. Wine's support for the 2010 version isn't polished so I'm looking for Linux based similar programs. I know that this can be subjective so I'd like to know what's the best Ubuntu alternative which has the most similar, and significant features as that of AutoCAD 2010? I'm not familiar with the program because I'm researching this for my sister who is studying Aeronautical Engineering. Any help is appreciated. I'm using 12.04 64-bit on my ThinkPad R61i with 3.8GB memory and 160GB hard drive.

• Computer sending data while turned off

  - by Nicklas Ansman

  I have a some what strange problem (which could have and easy and obvious solution for all I know). My problem is that when I've booted ubuntu (now 10.4 but same problem with 9.10) and turns it off it starts sending a HUGE amount of data via the ethernet cable, so much in fact that my router can't handle it and stops responding. As far as I can tell the computer is completely turned off with no fans spinning. I can add that if I boot windows I do not have this problem, just when exiting ubuntu. There are two "fixes" for my problem: Pull the ethernet cable until the next boot Turn off power to the PSU and wait for the capacitors to unload Is there anyone who knows what could be going on? I'd be happy to post some logs or conf-files. Currently I'm using the ethernet port on my motherboard which is a Asus P6T Deluxe V2 with an updated version of the BIOS (maybe not the latest but since it only happens when I've been in ubuntu I don't wanna mess with the BIOS too much). Regards Nicklas ---------Update 1---------- The router is a D-Link DIR 655 with the latest firmware. ---------Update 2---------- I've now reinstalled ubuntu (with 10.4) and I still experience the same problem.

• Stuck on Ubuntu Startup Screen

  - by Pietro

  Since yesterday, my system won't get past the startup screen (the Ubuntu logo with the blinking red dots). I left it for over an hour and didn't get the login screen. It was working normally before that and I don't recall any changes (no new software, etc). I can login through the terminal with ALT+F1 but I don't know what to do to get the graphic mode. The command startx fails. I'm running Ubuntu 12.10 64 bits on a Core I5 with Intel motherboard. No video card or sound card.

• Setting up Ubuntu on my mother's computer

  - by idealmachine

  Intended use My mother had an old Compaq desktop computer running Windows 98, which she used for occasional Web browsing and playing cards. The name of her card game is Hoyle Card Games 3. Although I had to repair it several times over the last 10 years, it worked fine until it finally died at the end of last year. Hardware specifications A relative brought up a newer computer soon afterward: Operating system: Windows XP Asus K8N motherboard (with broken on-board sound; getting a sound card) Athlon 64? processor (don't remember the clock speed) 512 MB RAM Hope the graphics card works... Replacement sound card will be one of: Ensoniq ES1370 AudioPCI Diamond Monster Sound MX300 (Aureal chipset) Sound Blaster Audigy 2 SE Peripherals HP Scanjet 3400c scanner (USB connected) HP LaserJet multi-function printer (parallel port connected, and printing works with a PCL driver) Same serial mouse as old computer Question I had set up an SSH/VNC connection to allow for remotely working out problems. Or so I thought. A month later, the computer would not boot, rendering the SSH connection useless and an OS reinstall necessary. Unfortunately, I have neither the original Windows disc nor the product key. Unless I were to pay $200 for a full Windows 7 Home Premium license for my computer, I would not be able to re-install Windows XP on hers. I consider myself an advanced Linux user, having used Debian for years. So here are my questions. I have only one day to decide whether to use Ubuntu or buy Windows: A quick search leads me to believe all the hardware listed above is supposed to work with Linux, but am I mistaken? Would Ubuntu/Xubuntu suffice (specify which one if it matters), or would I be better off paying the $200 necessary for Windows XP? Is the card game likely to run on Wine? I believe the minimum system requirement is Windows 95. Failing Wine compatibility, will VirtualBox run fast enough on such a computer (Windows 98 as the guest OS)? Are there any free card games just as good? She plays mainly Bridge, Poker, and Solitaire. Is there any "Large Fonts" option for those with poor vision? The lack of it would be a big disadvantage. BONUS: Although I would probably replace the old mouse upon a move to Ubuntu, is it even possible to get a serial mouse working?

• PAE on Ubuntu 12.04

  - by JamesStewy

  I am having trouble using PAE on Ubuntu 12.04 LTS 32bit. I recently upgraded from 4 to 8gb of RAM but PAE doesn't appear to have picked this up. When I run "grep --color=always -i PAE /proc/cpuinfo" I get pae in the list. When I run "dmidecode | grep Size | grep MB" Installed Size is 3825 but the Maximum Total Memory Size: 8192 MB. When I check the BIOS it says there is 8192 MB available and the computer fully supports I have followed everything I can find on the internet (including this https://help.ubuntu.com/community/EnablingPAE) and nothing is working. My Computer is a Toshiba Portege m750. It has an Intel Centrino Core 2 Duo processor. Bought in 2009 Thanks, JamesStewy

• ubuntu 12.10 graphic does not works correctly

  - by Amin

  I have installed Ubuntu 12.10 but my graphic does not works correctly. I used this command to installation: sudo apt-get install fglrx fglrx-amdcccle fglrx-dev But after the restarting my system, the side panel and upper one does not appear any more! I guessed it maybe that I used some incompatible packages so I removed the graphic card driver by this command: sudo apt-get purge fglrx fglrx-amdcccle fglrx-dev and tried it from graphical way from system setting > Software Sources > Aditional drivers and choosed the second option then applied change. But the resault waas such as before way!! I belive it is because of the Ubuntu does not know my graphic card. I am using VAIO VPCEA2TGX (N/A) and my graphic cart version is Mobility Radeon HD 5400 Series if it is matter. So now what is the exact problem and what I have to solve this?

• Ubuntu 12.04 installation freezes at "Detecting File Systems"

  - by user67970

  I am installing Ubuntu 12.04 onto my system, which I am dual booting an already installed version of Windows 7 with. The installation goes fine until what I suppose is near the end of the entire thing, where it is at the page where it scrolls through the features of Ubuntu. At this point, it is saying: Detecting file systems... It will not go past this point, and it has been at this part for an hour and a half. What should I do to fix this? I am new to working with Linux operating systems, so please help!

• How to overwrite Ubuntu with Windows 7?

  - by Will Cowled

  So I have a Windows DVD and it works. But when it gets to the part when it says "Upgrade" or "Custom" I click on custom and at the bottom it says cannot install over it because Windows 7 can only be installed on an NTFS drive? I know that Ubuntu formatted my partitions into one big on that's an ext4. What can I do? I know that I can maybe create a 30-50 GB partition that's an ntfs then when I go into windows I can format the Ubuntu one and combine them but I don't know how to make a partition much less make a big partition in the "GParted" program? So any ideas would be very helpful. I know how to do anything with a hard drive using the default program that comes with Windows 7 but I feel like a mouse in a maze when I open GParted.

• All network devices freezing when Airport Extreme Base Station is connected. Any ideas?

  - by Jon

  I've been troubleshooting this issue for a while, and through a series of events have it narrowed down to my airport extreme base station. I like this router, since I'm able to connect to IPV6 sites without any insane configuration (my alternate router is too old and doesn't support v6). My question is: Has anyone else had this issue, if so how is it resolved? If not, can you recommend a good IPv6 router? Here is how I came to the conclusion that it is the router: Devices: XBOX 360, HTC Incredible, Home-Built machine running FreeBSD, Home-Built machine running Ubuntu 10.04. 1.) Noticed freezing on Ubuntu Box. 2.) Noticed freezing on XBOX360 3.) Noticed freezing on HTC Incredible (only when connected to my network wirelessly). The above all happened at random times throughout the past few weeks. Over the last few days, I was playing XBOX and noticed that the XBOX and Ubuntu machines both froze. I picked up my phone, and it was also frozen. I reset all devices, power-cycled my router, and all was fine again. About two hours later, it happened again (I was playing Forza III, the XBOX froze; I went to the Ubuntu box and it was frozen; unfortunately, the HTC phone was not connected wirelessly, and the FreeBSD box was turned off). I can't even begin to imaging what a router could be doing to freeze devices with such differing hardware/software/OS, and I feel absurd for coming to this conclusion, but I have nothing else. I hooked up my archaic Netgear router, and have had no problems since. :(

• Ubuntu 10.10 crashing on initialization, how to solve?

  - by Tom Brito

  Yesterday I installed Ubuntu 10.10, and on the first login it got frozen, so I powered off and on the computer, and it started well. Now, during the updates it got frozen again, and after every login again. I can't even change to the command line with ctrl+f1 or f2. Is there a way to get some log information on the initialization? I have no idea what can be causing this. Previously I was using Ubuntu 9.04, which is now not receiving new updates. Versions 10.04 and 9.10 behavior the same as 10.10, and version 11.04 crashes much on many situations. So, is there a way to get some log information on the initialization to help find what's wrong?

• Additional Drivers error installing in Ubuntu 12.04 (wireless internet and software modem)

  - by gabiro

  I've already search for similar problems but they are so different from mine. these are the drivers http://db.tt/qFZlD5JD I'm having problem with this Additional Drivers once I click the Activate button it will start in downloading and installing but after that it will say Installation failed. Then the "Enable Wireless" will not be available. With the Software Modem issue is the same problem with the Broadcom. These drivers are working on Ubuntu 9 and 11 if I'm not mistaken. Only on 12.04 is not working. One more thing these drivers will enable the Huawei E165g E220. I've already tried other solution for the Huawei to activate but all didn't work. After a restart Enable wireless becomes okay, though. To all Ubuntu experts and masters please I'm begging for help. A million Thank You!.

• Ubuntu 12.04 crashes on startup for newer versions of Linux, possibly related to WiFi

  - by Jake

  My computer gets to the screen with the Ubuntu logo and the orange/white dots, and then the screen goes black, spits out a lot of error messages, and cannot boot. (If it'd be helpful, I can take a photo of my screen in this state.) I've found I can successfully boot if my wireless card is turned off. As soon as I turn it on, my computer crashes with the same black screen of death. I can also successfully boot if I choose "Previous Linux Version" and select a few versions back (I think 3.0.6). Here are some relevant details about my setup: Ubuntu 12.04 Computer: Lenovo x230 Wireless: Realtek RTL8188CE 802.11b/g/n WiFi Adapter Processor: Intel Core i5-3210M CPU @ 2.50GHz × 4 RAM: 16 GB of RAM Thank you!!!
