• Get root access for copying files to /usr/share/...?

  - by Vinaychalluru

  To be short, I want to copy a folder to a location /usr/share/screenlets/..... I don't know how to do it. I am using Ubuntu 10.04. I tried by logging in as root from terminal giving "su with my password". I even changed my user account type to ADMINISTRATOR by giving the root password when asked, yet, no use. Think all of you know that, even the option PASTE in the context menu's list in the folder "/usr/share/..." is INACTIVE. How can I copy those files?

• Java on easypeasy

  - by Beatriz Rojo

  I have successfully installed easypeasy in an Asus EeePC. I want to use the authoring programm Hot Potatoes, which is/uses a Java application (sorry for my poor technical vocabulary). It is installed and extracted. I have found guidelines about how to use it here (it is in German but the instructions for the terminal are clear). But it seems I cannot install any Java package. I have tried all the packages the terminal says are available and this is what terminal says: "Unable to find the package". In ubuntu I use Hot Potatoes with wine, but I cannot install it in the Asus, so I need to run it with java. Thanks for your help.

• installing 12.04 failing

  - by Steve

  I just downloaded 12.04 burned it to a cd, and booted to into it on my last built computer. It loads a purple screen, then goes to a dos looking screen with a blinking cursor then loads the ubuntu loader. The lights go from red to white and finally they all turn red. This is when the entire screen goes to noise and just hangs. Seems like a hardware issue but I can successfully boot into a non genuine windows7 that I'm looking to replace. I'm not sure what to try, so any help would be appreciated. Thanks.

• How do I turn off WLAN automatically when LAN is connected?

  - by derroman

  I use my Thinkpad laptop with a docking station. The docking station is connected to my router via LAN. When I walk around the house I use my laptop with WLAN. Is it possible (and how) to manage these devices with a script or something to work like this: If a LAN-Connection is up, the OS should turn off Wifi and if LAN-Connection gets lost (undocking) Wifi should turn on automatically. I use Ubuntu 11.04 64bit with Gnome 2. The system works on an Lenovo ThinkPad R500 with. WLAN-Device: Intel Corporation PRO/Wireless 5100 AGN [Shiloh] LAN-Device: Broadcom Corporation NetLink BCM5787M Gigabit Ethernet PCI Express (rev 02) Any help would be appreciated. Thanks.

• Cannot connect to wifi after downloading 12.04, repeated prompts for password

  - by Daytown3487

  I have had this OS for a little bit but this is my first upgrade and my first issue I am trying to deal with without my buddy who got my on Ubuntu in the first place (who is on the other side of the country.) I am running an IBM Lenovo T400 Thinkpad that had 11.10 on it and worked flawless. I upgraded to 12.04 a few weeks back and I have not been able to connect to the wifi in my home or anywhere for that matter. I have been trying to mess with it through reading the forums and am not quite sure what my problem is. I am running off of Fios Internet and the wifi keep disconnecting and prompts me to retype the password for reconnecting. If you guys could give me a step by step process of how I should go about fixing this I would GREATLY appreciate it!

• Debugging random reboots

  - by M132

  I'm running Ubuntu 14.04 with 3.16.1 kernel compiled from source, and when I leave my PC running for a long time, it always reboots after about 4-8 days. Nothing is displayed on the screen, everything just freezes for about 3 seconds (and if there was any sound playing, it keeps repeating over and over), and then reboots. This issue also affects kernels compiled by Canonical's build bots. I already tried to debug it with: rsyslog kexec-tools netconsole kernel module None of them seem to be working however. Are there any better methods to check, what exactly fails here? If there's an issue with RAM for example, shouldn't kernel report this in dmesg, or cause a kernel panic?

• Is there any simple C++ code to grab video from UVC webcam and display it simultaneously?

  - by mShero

  I'm very very new to Linux and programming! I'm using ubuntu 11.10 - 64 bits with gcc 4.6.1 I've been searching online for an example C++ code that simply grabs video from a compliant UVC webcam and displays it simultaneously.. I need to compile it on gcc. In OpenCV, it's a very simple code less than 20 lines as I remember! I found this: http://v4l2spec.bytesex.org/spec/capture-example.html But it's very huge code relative to OpenCV code ?! and even when I tried to compile it using gcc.. I got many errors! I copied the code into a cpp file: cap.cpp then wrote in the terminal: gcc cap.cpp -o cap and the errors showed up... same errors with g++ I hope if someone can help me and tell me where can I find another simpler code? and how can I test it ? Thank you :)

• Playing audio stream not showing in pavucontrol

  - by user168505

  My Pulse Audio Volume Control (pavucontrol) is not shown volume bar which present below the volume control slider for right and left channels in the Play tab . However, I can hear audio,and the pavucontrol Play tab shows the name of the application(any media player vlc,mplayer etc.) which is running and volume control for right and left channels (FROM LEFT & FROM RIGHT Volume slider) I guess there may be a change in the system configuration/setting? How to reset it? I have reinstalled Pulseaudio, but the problem remains. I am using ubuntu 12.04 with default pulse audio.

• How do I get the name of a package, modify and install it?

  - by Ken

  I'm not very familiar with Ubuntu or Linux, but I'm a programmer, and some people told me that you can just go ahead and modify your system. So my question is, how do you go on about that? For instance, If I'm interested in modifying the behavior of the button or the desktop icons, or whatever it is: How do I get the source code? I guess I need the package name and download it. But how can I get the package name? Let's say I want the button package, where do I look to get the package name? is there a list on a website or a help file? Once I modify it, how can I replace the original with the new one? P.S. I had some troubles finding the right tags, feel free to edit them

• .xprofile isn't enough

  - by BrianXP7

  I've been trying to find a solution on how to change the screen resolution on the login screen and other users. .xprofile will only affect my account. I've been searching for a few months but I got nothing. Please help. It would be easier if the "Default Resolution" was still there in the monitors settings. Plus, I'm afraid of editing the xorg.conf. Last time was ugly...

• Installing 12.10 on Dell r710

  - by user115490

  I have been trying to install Ubuntu 12.10 on a Dell r710. I have 6 disks in each 2 TB. I setup a raid 5 in the HW raid controller with all drives, and proceeded with the OS install. When the partitioner runs it fails to create / for some reason. I then tried just setting up a simple raid 1 with 2 drives in the HW controller, and doing the OS install again. The installer runs fine this time. Once trying to boot I then get a kernel panic of 'Target File System doesn't have requested /sbin/init' as well as a bunch of 'deleted inode referenced'. Can someone tell me what I am doing wrong here?

• Can I get some advice on graphics cards please?

  - by Victor9098

  I know that Steam for linux is on the way and have been seen a lot of games appearing in the Ubuntu Software Centre of late but my system lacks a decent graphics card and was hoping I could get some recommendations. The desktop is a Packard Bell Imedia S1800 (or Imedia D3526 UK) with the following specs; Memory: 3.8 GiB Processor: Pentium(R) Dual-Core CPU E5800 @ 3.20GHz × 2 The system lists the graphics as 'unknown', though I think its just an integrated Intel card From what I can see there is a free PCI-E x16 slot. Any advice would be great, thanks!

• Do I need the ATI driver or open source for dual monitor setup (ATI HD 4350 - 1GB PCI-e) in Pear Linux 12.04?

  - by Geeve

  I think I covered my question in the title. Right now both monitors are mirrored (both 19" at 1440x900). I guess what I need to know is do I need the ATI proprietary driver or will the open source driver from Ubuntu (additional drivers) work? I want to expand the desktop between the two monitors. Still finishing install and running updates now, I just wanted to gather all documentation and downloads prior to doing what is necessary. Any help will be greatly appreciated.

• Wrong EFI System Partition GUID?

  - by artificer

  On a new GPT initialized disk (second PC disk) I created a FAT32 partition using gparted. I want to use it as an EFI System Partition so I flagged it as boot. After that I checked the UUID using the gparted “partition information” option and it reported: 09B1-97A5. As far as I understand it should be C12A7328-F81F-11D2-BA4B-00A0C93EC93B. I also checked my running operative system disk (Ubuntu 14) and found that Gparted reports EB78-9AD2 for my actual boot partition UUID. What exactly is gparted reporting as UUID on my EFI system partition and why it doesn’t match with the expected C12A7328-F81F-11D2-BA4B-00A0C93EC93B ID?

• Wi-Fi connections gets Idle

  - by marcocamejo

  I am having this terrible problem. I have read a lot of people getting disconnected from the Network, it is not my case, I don't get disconnected, the connection just gets "idle" most of the time. It only works for short periods of time (seconds, a couple of minutes at most), then gets dead, then works again, and so on. It is annoying. I am using Ubuntu 11.10 on a Dell M5030 laptop. I have Windows 7 installed too, and of course with it, the wifi works perfectly. Any idea? advice?

And despite I completely reverted to my one-screen-X-config the gnome-panel displayed has 4 rows (4 at top sreen, 4 at bottom) only the outermost row has content, the other 3 are empty there is only one gnome-panel process running some widgets appear 4 times, too, although they run only once when I switch away from openbox using unity I am back to 1 row temporarily What went wrong here? How do I undo that? Things that did not help: rm -Rf .gnome2 .gconf/ .compiz-1/ pkill panel, and restarting it

• Flikering line on top of display

  - by jaskaran

  I just bought a new Dell Inspiron pre-installed with Ubuntu 11.10. All was fine until I updated the OS. Since then, I have this flickering line at the top of my screen and it won't go after rebooting or changing the screen resolution. It gets really annoying. I don't know which update did this. I tried reinstalling the image from Dell, and it worked fine until I applied the updates. I tried to take a screen shot but it does not show. The line seems to be outside the desktop area. Help please... Thanks!

• Logitech C310 webcam problems

  - by haggai_e

  I've just installed a Logitech C310 webcam on my Ubuntu Oneiric machine, and I've got several problems. When I use cheese, if I set it to use the higher resolutions, the picture contain shadows and has distorted colors. Only with lower resolutions the picture looks okay. The above photos were taken with cheese. In addition, the camera's internal microphone didn't always work. When using it through pulseaudio, the sounds were fast and with high pitch. When using it directly through alsa it sounded fine. Any ideas?

• I just updated to 12.04 from 11.10 and now the Unity bar is very sluggish and even the menus do not show on the panel

  - by jredkai

  Like the title says, I just upgraded to 12.04, I know it is only beta but I'm having problems with the Unity bar and the panel with the menus. First the Unity bar is acting very sluggish..I really don't know how to explain it. Also with the menu at the top, it keeps a strange little black bar on everything, even across my tabs in Firefox, it also doesn't let me see any of the menus, well they flicker and you sort of have to guess where everything is. I'm at a loss, I've already ran updates a couple of times to see if I missed something. I really hope I don't have to completely redo my whole Ubuntu setup. Any help would be greatly appreciated.

• How do I allow a non-default user to use serial device ttyUSB0?

  - by lucaghera

  I have an Ubuntu 11.10 system with 2 users: The first was created during the installation The second instead was created after. It belongs to the sudoers group. Now the problem is that when the second tries to use a device ttyUSB0 the following error is returned: "Could not open serial port /dev/ttyUSB0" I was able to fix it by using: sudo chown :second_user /dev/ttyUSB0 However when I disconnect the device and reconnect it the problem comes back. Is there a way to allow different users to access the devices? I suppose I have to add the user to a specific group. Currently the owner is root and the group is dialout. However I'm not sure about the group and I don't know how to add the user. Thanks!

• Multiple network installs with cached downloads

  - by popey

  I tend to do lots of Ubuntu installs, and I'd like them to be up to date from the moment I do them, and not have to install a bazillion updates as soon as the install finishes. I'd also like to cache those packages somewhere on a machine on my LAN, so I don't re-download all the packages every time. How easy is this to achieve? Is there a guide somewhere to making this happen? Bonus points if I don't have to burn any CDs or use USB sticks! Edit: I have noticed a lot of guides for PXE booting and would be tempted to set this up but every time I find one they seem to be old/outdated and broken. My home server runs 10.04 LTS.
