• Battery issues on Dell Inspiron XPS14z Ultrabook

  - by querolus

  I'm new in the Ubuntu world. I just bought a Dell Inspiron XPS 14z Ultrabook and installed Ubuntu to dual boot with Windows thanks to the Ubuntu Secured Remix package. Everything works fine except the battery. I have, at most, 1h 30' battery life. With windows it can last more than 3h. Moreover, and I guess it's related to the battery issues, the fan is constantly running at high speed while it does not when working with windows. Do you know where can be the problem?

• Missing launcher, top panel without icons, an ATI driver problem?

  - by jlotero

  After upgrading to Ubuntu 11.10, the following problems occurs when accesing in ubuntu mode (3D): the launcher is missing, top panel without icons on the right side, and I can only restart with Terminal (Alt-T and then sudo reboot). No problems in 2D. It occurs on my PC with AMD Athlon (tm) II X4 640 Processor, Radeon HD5670 and both with the 32-bit and 64 bits versions of Ubuntu. Both versions work well on an older PC with AMD Athlon 64 x2 Dual Core 4200 + processor, and an Nvidia integrated graphics card (C61 GeForce 6150SE nForce 430). Could it be a problem with the ATI driver?

• Wifi very slow on Ubuntu 12.04 but not on Win7, need help

  - by user84504

  I have an enormous problem: I've a Sony Vaio VGN-NR21S with win7 and Ubuntu 12.04 in dual boot. With Windows everything is fine (except that is windows) but with Ubuntu the wireless connection is awfully slow, basically unusable. I've already search for similar discussion but the solution proposed didn't worked. I've noticed this issue also in live mode both with ubuntu and linux mint. I've installed Ubuntu onto an Acer that shows the same problem when connected via wifi to my router, so I think that maybe the issue is about compatibility with my home router. I really need help, I don't want unistall ubuntu! Please tell me which output u need to help me, thanks.

• Productivity strategies for one developer using many PCs

  - by DeveloperDon

  In a talk about time management, a famous computer scientist said: "One machine in your life is the right number." He recommended a laptop with a docking station. After trying this approach for about a month, I miss my more powerful desktop (i7 quad core hyperthread), but it is not in my technology road map (or budget) to upgrade from my old Intel Core 2 Duo (2006) notebook this year. What strategies can help me use the desktop while at my desk and without much manual effort the notebook when I am on the go?

• 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.

• Ubuntu freezes when gdm starts

  - by Enrique

  I have Ubuntu 10.10 (upgraded from 10.04) I was browsing in Firefox yesterday, then the PC suddenly did a reset Once it restarted, everything went normal until gdm begun showing. Then everything froze and locked when userlist showed. I can't move mouse pointer nor do anything with keyboard at this point (just after userlist shows in gdm). PS: Both, mouse and keyboard work fine, because this Ubuntu is dual-booting with a Windows XP install which loads/works fine. Here is my .xsession-errors file, but I don't have a clue what may be wrong. Thanks http://pastebin.com/GVtneEAF

• Asus 1001P freezes after chaging network settings

  - by auntiquarian

  I'm running Ubuntu 11.04 on a Asus PC 1001P in a dual boot environment with XP. All has been running fine for several weeks, but: I've just changed ISP (from Tiscali to BT), and had already sorted out connection, registration, etc. on a Dell laptop. On the Asus I went into Ubuntu to alter the wireless network details (i.e. selected the new network, and entered the password). Ubuntu immediately started running slowly, and after rebooting it now freezes when it gets to the Ubuntu logo and gets no further. Please help, lovely Ubuntu experts.

• Connecting to a Windows SVN server from Ubuntu

  - by skytreader

  I need to access an SVN repo hosted on a Windows machine from Ubuntu. However, even if I supply the proper credentials, it denies me access, apparently because Windows does not allow Linux connections (as they told me); sure enough, I got in when I tried to checkout from my XP partition. While I have my box dual-booted, it is inconvenient to switch just for SVN. So, does anyone know how I can access that SVN repo from Ubuntu? I've tried installing TortoiseSVN and Windows Subversion under Wine but I can't even get them to run; they were asking for some DLLs that I don't know how to supply. I've thought of installing a virtual XP just for SVN but I consider that too extreme and I'd be glad if anyone can advise a simpler workaround.

• cannot install ubuntu 12.04 using wubi

  - by vicky

  I recently installed windows 7 on my pc and I have been unsuccessfully trying to install ubuntu 12.04 on it. I used to have dual boot system before both with windows and linux. I changed my hard drive from ide to ahci (default option) burned the ubuntu cd properly (not the .iso file) using the ubuntu 12.04 distribution I downloaded from the official site, set boot priority to cd/dvd but.. Nothing. It tries to boot from the cd, doesn't manage and turn to boot from the hard drive. I also tried wubi. I opened it through windows, got the window that asks me to choose "demo and installation" or "more on ubuntu" (something like that), I choose the first option, reboot manually my computer and it keeps returning on windows mode and doesn't boot from the cd. What can I do? Thanks!

• Labeling algorithm for points

  - by Qwertie

  I need an algorithm to place horizontal text labels for multiple series of points on the screen (basically I need to show timestamps and other information for a history of moving objects on a map; in general there are multiple data points per object). The text labels should appear close to their points--above, below, or on the right side--but should not overlap other points or text labels. Does anyone know an algorithm/heuristic for this?

• Unable to boot from new SSD after installing from USB

  - by user73725

  I'm using a new SSD with nothing on it. It's installed via USB drive, and boots from USB as well. While in Ubuntu I can see the SSD and other devices. When I install from the desktop (have tried from the boot screen as well), system restarts. It takes me to the boot screen, select boot from first hard disk, nothing, goes right back to boot screen. When I take the USB out, it hangs on "Verifing DMI." If I boot onto the USB I can see the correct files located in the SSD. I have a basic knowledge of computers. Give me any thing you think would help. No other OS's are loaded. Gigabyte ga-k8n-sli 1GB RAM AMD Athlon 64 x2 dual core 3800+ OCZ SSD Agility 3 120GB

• Fresh install of 12.04 Kernel panic

  - by user70260

  I am attempting to install Ubuntu 12.04 on my computer. After the Ubuntu splash screen, the computer throws up this error: sr 2:0:1:0: [sr0] Unhandled error code Kernel panic - not syncing: Attempted to kill init! PID: 1, comm: run-init Not Tainted 3.2.0-23-generic #36-Ubuntu The computer hardware is as follows: Core 2 quad 9400, 8gb RAM, GTX 275, 3 Mech HD, 2 SSD, Win 7 install. I would like to dual boot Ubuntu on this computer if possible. I did try placing this disk in my laptop and booted successfully which leads me to believe the fault lies with the desktop. Under windows all hardware seems to work ok. Any ideas?

• Server 13.10 Install Hangs

  - by noloader

  I'm trying to install Server 13.10 on some old hardware for testing (HP/Compaq dc5850, with Athlon X2 2.3 GHz dual core, 4GB RAM). The third screen is "Select Language" and the machine appears to hang. Ath e selection screen, the keyboard and mouse does not work. I integrity checked the CD and it checked out OK. I also performed a second ISO download and it cross checked with my initial download: $ md5 Desktop/ubuntu-13.10-server-amd64.iso Downloads/ubuntu-13.10-server-amd64.iso MD5 (Desktop/ubuntu-13.10-server-amd64.iso) = 4d1a8b720cdd14b76ed9410c63a00d0e MD5 (Downloads/ubuntu-13.10-server-amd64.iso) = 4d1a8b720cdd14b76ed9410c63a00d0e I was able to install Server 12.04 on the same machine. The problem with 12.04 is the OpenStack packages are too old, and I wanted to try something with fresher packages. My problem appears similar to I cannot install Ubuntu Server 12.10. The Installer hangs at the language selection, but my ISOs appear to be good and the disc appears to be good. Any ideas?

• Full brightness and keyboard backligh at boot

  - by joelalmeidaptg

  I own an Asus N56VZ, and each time I start Ubuntu (13.10 and prior versions) my screen brightness and keyboard backlights reset their values to the max. Ubuntu doesn't save my settings on reboot. I was wondering if someone could help me with this? It is horrible when, at night, I turn on my computer - it is like looking directly to the sun, and it hurts my eyes. I tried googling and none of the pages I found actually helped. I think my issue might be grub-related. I have a dual-boot with Windows 8.1, so before I start my computer I see grub to choose my operating system. My screen starts at full brightness as soon as I reach grub. Maybe he is making the OS forget about my last values, overriding it with its? Does someone knows how to solve this? Thanks in advance :) PS: I'm using bumblebee with Nvidia driver 304, but this issue existed before I installed it.

• XNA move from start position to target position exactly in 3D

  - by robasaurus

  If I have a list of positions that map out a path a character should follow. What would be the best way to move at a constant speed to each position making sure the character lands exactly at each position before moving onto the next? For example the character is at position A, we then queue up position B and position C. The character cannot move towards position C until it reaches position B exactly. It would be great if the solution worked at slower frame rates/update speeds as well.

• Installed Ubuntu 14.04. How do I get it working with my new AMD R9 280X. When I run it I get garbage on the display

  - by user289455

  I installed Ubuntu 14.04 on my Gigabyte A88X FM2+ motherboard and A10 7700K processor. Everything worked perfectly. This system is dual booted with Windows 8.1 for gaming and I installed subsequently I installed an AMD r9 280X gpu. Windows was easy. It kept working with the new card installed and I just needed to download and instal the driver. Reboot and it's done. Ubuntu boots into a blank display. I enter the password and can log in. The menu on the left and bar at the top are visible but when I try to open an app, I get blocks and rubbish on the display. My preference is not to remove the card. So, my question is: What would be the procedure I could follow where I can log in using a text based terminal and download and install the AMD drivers.

• Changing read-write permissions on my external Seagate hard drive

  - by Anthony_JKenn

  I have an external hard drive (Seagate Free Agent) that I normally download files to. I have a dual boot Ubuntu 11.10 along with Windows 7-64 bit. I can read all of my files in my external HD perfectly, but when I attempt to do a download of a file to this drive, I get an "unable to write because of read only" disk error. When I attempt to change the permissions of the disk through the "Properties" bar, I still get an error that I don't have the proper permissions to change permissions. I have heard of "mounting" the disk, but I am afraid of mistakenly reformatting and destroying all the data that I have currently on that drive. How best should I safely change the permissions on that drive so that I can write and download files to the drive?? The drive is listed under /dev/sdc1.

• Logitech Wireless Keyboard & mouse not working aftesr upgrade to 12.04?

  - by deerjay99

  I upgraded my Dell Dimension 9200C to 12.04 Precise Pangolin with no issues, I ran it fine for a night but when I went back in a couple days later my Logitech Wireless Keyboard K350 and M510 mouse weren't active when booted. I can boot into an older version from the main the boot screen the mouse and keyboard work, but the network stack is gone. It says the networking manager on this version is not compatible. I'm scratching my head, it isn't the mouse and keyboard, they work fine on my dual boot, and they load fine in Knoppix. They did work fine on 12.04 for 1 night. Open to suggestions before I re-install completely.

• Ubuntu freezing after boot

  - by jbm1991

  I have ubuntu 12.04 LTS dual booting with windows 7 on my laptop without any problems and felt like doing the same on my desktop. However now that I have installed Ubuntu on the desktop through Wubi, if I boot into ubuntu the log in screen is as far as I get. I see my username and the password box but everything is completely unresponsive. I can move the mouse around the screen fine I just can't click on anything and the keyboard doesn't seem to work at all as I've tried a few shortcuts and there's no response at all. I have done a some searches and I think it's a driver issue but I don't know how to fix them as I'm pretty new to ubuntu and cannot log in at all. Desktop specs if needed: Intel core i7 2700k, NVidia GTX 580, 8GB RAM. Thanks in advance

• Changed profiles; lost Ubuntu; how do I get it back?

  - by Tim

  Installed Ubuntu-secure-remix 12.10 in a dual boot with Windows 8 on an HP laptop. A first-time Linux user, I was exploring settings when I changed profiles (not sure what I changed it to). Now the Linux boots into what I believe is the shell. I can still log in (that is, I am already a user - so that's still there). Due possibly to using rEFInd, I cannot figure how to run Ubuntu in recovery mode. How can I get Ubuntu back up and running again? Thanks in advance.

• Unable to Boot Into Windows 7 after Ubuntu 10.04 Update

  - by PlantGuy

  I'm running a dual boot Windows 7 / Ubuntu 10.04 system. I ran the Ubuntu update last night, and today when I tried to boot into Windows 7, it goes straight to the windows recovery on my Acer 5517 laptop. I've spent the entire day trying to resolve this with no success. I used my Windows 7 Recovery Disk to reset the mbr, but that didn't help. The system was working perfectly prior to the update. It appears that now Grub is pointing to the recovery partition rather than the primary partition. Any help will be greatly appreciated. I don't relish the idea of reformatting and starting from scratch.
