• What happened to my files?

  - by Ivan Broes

  After a successful upgrade from 11.04 to 11.10 a gradual deterioration occurred -- my laptop became unstable with updates -- I corrected the Aspell file, only to have another appear, I sought but I was blocked out. Had an idea, but resolved one that another problem appeared -- going from bad to worse -- I re-installed windows Vista and Ubuntu 11.10 in the original partitions. Window called it Windows Old and I had no problems recovering my files there - Ubuntu decided it is going to make a new Home directory -- . the questions is where did these files go to after re-installation -- are they deleted? If so That's fine duplicates are in Ubuntu 1 by synchronization - I can only download one file at a time!

• purple screen when booting on lenovo G505s

  - by user1114795

  I successfully installed Ubuntu 14.04. I'm having the purple screen issue however even after making the nomodeset changes. It remains stuck on a purple screen. I can navigate through the menu options i.e Ubuntu, Advanced Options for Ubuntu, Memory Test, Windows Recovery Environment and Windows 8. I can't even boot into Windows 8. I'm totally new to this. If someone could please provide step by step instructions, that would be most appreciated.

• How can I fix intermittent iSight camera functionality on a Macbook Pro 5,2?

  - by Mmmm

  I have a Macbook Pro 5,2 laptop dual booting OSX and Ubuntu. The built-in iSight video camera works only sporadically. By that I mean that sometimes if I boot and try to use the camera it does not work (most of the time) but other times it does. I don't have good repeatable data regarding when it does vs. when it doesn't other than to say that it always seems to work right after I upgrade to a new Linux kernel with the Update Manager and reboot, but then eventually stops working again until I upgrade the kernel again. That is hard to test repeatably, so it's hard to know for sure that that is the case. This has happened consistently with every version of Ubuntu from 10.10 through 11.10. I can get around this by booting into the OS/X partition, since all of the hardware obviously works perfectly on that side of things, but it would be great if I could remain in Ubuntu and do the same thing. Thanks in advance for any inSights.

• Launch Rhythmbox using a Keyboard shorcut

  - by palerdot

  I use Rhythmbox all the time in my Ubuntu. Is it possible to have a custom shortcut like Ctrl+R in Ubuntu, which can launch the Rhythmbox window, even if it is playing in the background ? Since, the emphasis of Linux OS flavors is to use keyboards as much as possible instead of mouse, i thought this functionality might tremendously help me in my Ubuntu environment. The Keyboard shortcuts sections asks for a command; So, I'm not able to figure out how to give a custom keyboard shortcut to a program like Rhythmbox. I'm using 12.04 if that helps. Thanks.

• Cann't find shared folder anymore

  - by SoftTimur

  I use VMware Fusion under Mac, and I have installed Ubuntu 12.04 and Windows 7 as virtual machine. Under Ubuntu, by "shared folder", I used to manage a common folder with Mac via /mnt/hgfs/myfolder. Under Windows, I have set up so that this folder is also accessible. But today I cann't find myfolder anymore under /mnt/hgfs in Ubuntu, while it is still accessible via Windows (and Mac of cause). I tried to restart the machine, reset the sharing settings, it still does not work. Could anyone help?

• Adding PPA on install

  - by trampster

  I have a app I am packaging for ubuntu. I don't like the idea that if included in the ubuntu repositories I will have no control over updating that application. I don't want my users stuck on an out dated version for up to 6 months. I also do not want my users to have to manually add a PPA themselves to get updates as the target user will not have the technical know how to do this. Is it OK to have my .deb add a PPA on install. So that I can roll out stable updates to my ubuntu users.

• Freezes if desktop effects is used [closed]

  - by munir

  I have found that using desktop effects in Ubuntu versions later than 8.10 causes the desktop to freeze after a few seconds on my PC. the command lspci -nn gave the following 00:02.0 VGA compatible controller [0300]: Intel Corporation 82945G/GZ Integrated Graphics Controller [8086:2772] (rev 02) and with lspci -k I have 00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02) Kernel driver in use: i915 Kernel modules: i915 The intel graphics cards seems to have some performence issues with xorg driver. However I have not noticed any freeze in Ubuntu 8.10. There are some workarounds at https://wiki.ubuntu.com/X/Bugs/Lucidi8xxFreezes to make them work. But I can't find out what workaround should I do with my graphics controller. I have tried workaround F but it did not help. can anyone help me find a workaround for my graphics card? and is it actually possible to use desktop effect in this graphics card ?

• xrdp setup over ssh

  - by Xianlin

  Here are the steps to install xrdp on ubuntu 12.04 and get it working: http://www.ubuntututorials.com/remote-desktop-ubuntu-12-04-windows-7/ However, I want a secure xrdp connection over ssh and I am able to achieve it by using port forwarding in the software putty as below: L1234 == localhost:3389 But I am still able to remote login to the ubuntu through xrdp connection when I am not connected using SSH. It is supposed to deny remote login when SSH is not present. In the file /etc/xrdp/xrdp.ini I tried to change the [global] section by adding "ip=127.0.0.1" and it didn't work.

• Optimus Bumblebee Performance

  - by Chance

  After installing Ubuntu 12.04 and Bumblebee, I tested out the performance of the Nvidia card using Minecraft and a few other games. I've noticed it to be way slower than it was on Windows 7. Is this normal? I'm using the GT 630m. From what I've read online, nobody has said it to be slower than Windows. I'm just really curious because I want to use Linux so much more than Windows, but if I don't get the same performance I feel really picky. The Nvidia card is still faster than my Intel graphics on Ubuntu, but it's not as fast as it was for my on Windows. I get 60 - 80 fps on Minecraft on windows, while I get 28 - 48 fps on Ubuntu. Any Ideas why? Thanks so much!

• How to reduce noise in Skype?

  - by tkc

  According to Alsamixer I do have a HDA Intel soundcard with Nvidia MCP77/78 HDMI chip (Realtek sound card on MSI notebook). When I use Skype under Ubuntu 12.04 for video calls, the other side hears background noise such as in Windows when you have your microphone boosted. In fact they can hear everything, even the fans turning on. There is nothing tweaked on Ubuntu's fresh installation. Also tried this site: https://code.launchpad.net/~ubuntu-audio-dev/+archive/alsa-daily/+packages , but there are no *.deb files that I can test if any fix the problem. The question is if there is a way to add/tweak something to enable on software level the noise cancellation like the Windows sound drivers have that option. I use my build in mic.

• How to simulate a USB plug?

  - by Nicolas Delvaux

  I have an app that implements some automations when an USB key is plugged. While developing, I have to test it in a specific environment (derivative from Debian Squeeze). The app subscribe to HAL events via DBUS. The problem is: my desk is on the third floor while my test machines are in the basement. I would really like to have a way to simulate a USB plug. usbip does not work on Ubuntu. I can't manage to use the g_mass_storage module on Ubuntu (I lack the dummy_hcd module) and in Debian. Maybe it is possible to simulate a dbus call? My work station is on Ubuntu 12.04.

• Major problem with Nvidia drivers

  - by user38580

  Since I decided to use Ubuntu -yesterday- I've been struggling with the drivers. It isn't recognizing my optical disc drive nor my video card, a Nvidia 8500gt. For the matter, here's how I "successfully" installed the .run driver downloaded from Nvidia's website: The terminal wouldn't let me start the installation because the X server had to be shutdown, so I pressed Ctrl+Alt+F1 Then, I used: sudo service lightdm stop cd /(directory where the nvidiaupdate.run was) chmod +x nvidiaupdate.run sudo ./nvidiaupdate.run The installation began and got completed, but unfortunately it crashed Ubuntu's UI, invalidating the OS for me. All that would appear was a DOS-like screen with reports. I'm new to Linux, so I really would appreciate any help given. For now, I'm sticking to the additional drivers, but even with it Ubuntu doesn't show my video card in the informations of the system. Forgive my bad English.

• HP Probook touchpad

  - by ScienceSE

  I wrote about this problem some weeks ago, but now the question is: "Why is touchpad works not so good as in windows". I tried some "experiments": When I use windows and if I accidentally touched touchpad - cursor isn't moving, also no clicks occurring. So in windows working with touchpad is quite normal, but in Ubuntu ?f I accidentally touch the touchpad even with my wrist - cursor is moving etc. In Windows, the cursor moves only when I touch it with finger. And... If, for example, I hold one finger on touchpad and simultaneously move the second finger on the touchpad - the cursor doesn't move, however in ubuntu he does. He's "super sensetive" in ubuntu or what? Also I tried to apply the option in "Mouse and touchpad", which called "Disable touchpad when typing", but nevertheless he isn't disabling when i'm typing... Note: this option is circled in red frame, i dont know is it a good "sign" ) What can I do to fix the problem?

• Unable to mount location, Can't mount file

  - by user116008

  I'm a new user to Ubuntu and I have a problem: I had Windows XP in my computer and I had two partitions: C (for system data) and D(for my personal stuff), then, during the Ubuntu installation I chose the Advanced Settings and formated C partition and left D partition intact, went back and chose Install Ubuntu and replace Windows and it installed fine. The problem is that now I open Nautilus and go to Computer, in there it shows my D partition, 640 Hard Disk, but when I try to mount it displays me a message: "Unable to mount location. Can't mount file". I ask you to explain me step-by-step what I need to do because I'm not an advanced user. My computer specs: 2 GiB RAM, Proccesor Pentium(R) Dual-Core CPU E5400 @ 2.70GHz × 2, Graphics Unknow (It's Nvidia GeForce 220 {1GB} or something), OS type 32-bit, Disk 628.0 GB P.S.: My HDD is internal, I'm not using external Hard Drives. Thank You!!! Mike

• Mouse wheel on Dell Vostro V13

  - by Scaine

  I have a Dell Vostro V13, which Canonical claim is "Certified" for Ubuntu (http://www.ubuntu.com/certification/make/Dell/laptops). So it surprises me that the synaptics trackpad isn't recognised as such and defaults to psmouse emulation. This means no multitouch, no gestures, and more importantly, no mousewheel scrolling. Because it's not loading the synaptic driver, running gpointing-device-settings doesn't help. I've found this bug : https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/380126 which suggests a fix has been committed, but I can't see a way of getting this loaded on my Maverick build. I've tried backports and proposed repos in synaptic, but no joy. Any ideas?

• How to test 3d acceleration?

  - by HappyDeveloper

  I want to install and test 3d acceleration in Ubuntu 12. I have read these pages: https://help.ubuntu.com/community/RadeonDriver https://wiki.ubuntu.com/X/Troubleshooting/VideoDriverDetection?action=show&redirect=X%2FTroubleshooting%2FFglrxInteferesWithRadeonDriver#Problem:_Need_to_purge_-fglrx I think I have installed it correctly, but I don't know how to test it. I tried to play minecraft in the browser, but I got a black screen. It may be a java problem too, so I need to troubleshoot. So how can I test my video card and drivers?

• MacBook 5,1 - cant change brightness on 12.04

  I'm a total newbie to Ubuntu and recently decided to give it a go on my early 2009 Alu MacBook. For about a week now I've been trying to get the brightness controls to work. I've tried the following: Brightness controls doesn't work on a MacBook Pro 5.5 (ubuntu 12.04 LTS) https://help.ubuntu.com/community/MacBookPro5-5/Precise#LCD None of it seems to work. Next option was to try the Nvidia-bl-dkms drivers, but aftert installing the Mactel PPA I just get this: Reading package lists... DoneBuilding dependency tree Reading state information... Done E: Unable to locate package nvidia-bl-dkms Any help would be much appreciated as my eyes are going to fall out soon with the brightness maxed out.

• Windows 7 won't boot? Tried Boot Repair (dual-boot)

  - by user206870

  I downloaded Ubuntu and installed it so that my computer was dual boot. The first day, Ubuntu and Windows both worked great. Unfortunately, the next day, after messing around on Compiz Config Settings Manager to get the rotation cube, I tried booting into windows 7, and it wouldn't boot. It just goes to the screen where the Windows logo comes up and says Windows 7, and then reboots without even displaying an error message. I tried boot repair and it didn't work, the problem's still there. How can I fix this? PS: here's the link that boot repair gave to me: http://paste.ubuntu.com/6287090

• 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?

• How do I set the root password so I can use su instead of sudo?

  - by Zignd

  Warning: Directly logging in as root is like playing with fire, because one little typo is enough to lose critical data or make your system unbootable. Note that desktop environments will also function incorrectly if you login to them as root. See these questions for the reasons behind why sudo is preferred and why root-login is disabled by default: What are the benefits of sudo over su? Why is there no option to login as root? Instead of letting you set a password for root during install Ubuntu set it to * for no password and disables the actual account login, however even with this being said you can still use root in ubuntu by sudo. So how to set a root password on Ubuntu?
