• Design difficulty for multiple panel forms [closed]

  - by petre

  I have form that consists of multiple panel on the right, a treeview on the left and a terminal richtextbox on the bottom. When i click on a node of the treeview i bring up the panel that is attached with the node. For example i have 10 nodes on the treeview, i have 10 panels that are attached to this nodes. On every panel, i have many textboxes, labels, comboboxes etc. I don't dynamically construct and dispose the items on the panels, i create the items in the designer file of the project. In that case, there is a problem. I really find it difficult to align or place items on the panel because there seems a lot of aligning lines on the screen. What should be done to make the design of the panels easy? I don't want to construct items dynamically. Do i have to do that dynamically or is there a design procedure that make this process easy?

• How to run a complete GUI as root?

  - by Braiam

  I don't care if I mess up the system (which is likely if I do things like this), or the potential security issues that this could imply. Note, that I don't just want to "enable root login?", but run my GUI from bottom-up as root. I don't want to type my password for anything but just for login and have total control over it. Of course, I want any application running as root, like Firefox, LibreOffice, etc. without having to mess up with the terminal. So, how do I do this?

• Is there a way to recover a file that I have deleted but is still open somewhere?

  - by George Edison

  This question is related to How to recover deleted files? but it is slightly different in nature. Suppose I have a file named ~/something open in a text editor. Further suppose that I open a terminal and run the following command while the file is still open in the text editor: rm ~/something This will delete the file. Now suppose that I changed my mind and wanted to get the file back. The file is still open in the text editor, so it hasn't been removed from the disk or filesystem yet. Is there any way to recover it?

• Window controls missing; Cannot maximise or minimize applications

  - by omg_scout

  Ubuntu 12.10 32 bits, fresh installation. How can I make Unity maximize or minimize a window? I see no button,option, anything, do I miss something big? Quick googling did not give me a piece of answer, too: On first screen, I have a terminal window. Only clue about maximizing it I found was pressing F11 which made it fullscreen, hiding left bar as well. I would prefer it to take whole free space instead of whole screen. How can I do that? On second screen, I have an opera browser which takes bigger part of the screen but I can't make it take whole screen. Restarting opera did not work. How do I minimize/maximize apps? Also, in case I would like to see the desktop, only solution I found was closing everything Help guys. I kind of like new GUI, but I can't have simplest tasks done there, I feel like I miss something big there.

• uswsusp won't hibernate with freeplane and some websites open

  - by Richard

  I installed uswsusp on my laptop to hibernate faster, which works most of the time, but whenever I have freeplane (and some websites in firefox...can't recall which ones but can probably find some) it fails. In order to hibernate, I have to resort to closing the offending program or webpage - but this kinda ruins the point of hibernating... It fails when I try sudo s2disk in a terminal with freeplane open, but strangely works with sudo s2ram --force. When it fails, it simply switches to the black screen with s2disk: Snapshotting system but then returns to the login screen. When I enter my password, the hibernating indicator continues flashing but goes back to the desktop I left when trying to hibernate. When it works, it works as expected from hibernate, shutdown and resume. I saw another thread discuss fglrx modules and to include it in MODULE="fglrx" in /etc/default/acpi-support, but that hasn't helped me. I'm using Ubuntu 11.10 with an ATI graphics card on an Acer Aspire 6920.

• Recovering a deleted partition

  - by Kishore

  I had a dual boot PC running Ubuntu 12.04 and Windows 7. About a month back, I deleted the Ubuntu partition via the disk management utility (I do not remember whether or not I formatted the partition after performing this action). I ran into some grub issues and used lilo to solve the issue. I followed the simple instructions described in this blog post. I now realize that there were some files in the Ubuntu installation that I need. Of course, I backed up the data, but not this folder apparently. Is there any way to get the data back? I tried following the process suggested on another post on askubuntu (suggesting the use of TestDisk), but was not able to even install TestDisk. The live USB I use is running Ubuntu 12.04 and it does not have a synaptic package manager. Installing from the terminal does not work because even after I type: sudo apt-get update sudo apt-get upgrade the command: sudo apt-get install testdisk fails to work.

• Why do I get a 403 error when accessing my apache server?

  - by nishan

  Im running Ubuntu 12.04 LTS on a system with 2 GB RAM and a 500 GB HDD. My hard drive has 4 partitions: Partition 1 = 40 gb Windows (NTFS, lable = win32) Partition 2 = 320 gb Windows (FAT label = common) Partition 3 = 40 gb Ubuntu (EXT4) I installed apached2. Then, to change its default www directory, I ran gksu gedit /etc/apache2/sites-enabled/000-default and, in the editor, changed the location to /media/common/www. After that I ran these commands in a terminal: chmod 777 /media/common/www chmod 777 /media/common/www/*.* After that I ran: firefox 127.0.0.1/index.php It said: Forbidden You don't have permission to access / on this server. Apache/2.2.22 (Ubuntu) Server at 127.0.0.1 Port 80 Before my changes it was working fine. How can I run my websites?

• Setting umask globally

  - by DevSolar

  I am using a private user group setup, i.e. a user foo's home directory is owned by foo:foo, not foo:users. For this to work, I need to set the umask to 002 globally. After a quick grep -RIi umask /etc/*, it seemed for a moment that modifying the UMASK entry in /etc/login.defs should do the trick. It does, too -- but only for console logins. If I log in to my desktop, and open a terminal there, I still get to see the default umask 022. Same goes for files created from apps started through the menu. Apparently, the display manager (or whatever X11 component responsible) does source some different setting than a console login does, and damned if I could tell which one it is. (I tried changing the setting in /etc/init.d/rc, and no, it did not help.) How / where do I set umask globally, so that the X11 desktop environment gets the memo as well?

• SSH access failure from Ubuntu 12.04 LTS VM

  - by begueradj

  I installed 2 VMs on VirtualBox. VM 1: Windows XP with FreeSSHd and PuTTY installed.IP address: 10.0.0.2 VM 2: Ubuntu 12.04 LTS Server Edition with OpenSSH installed.IP address: 10.0.0.3 From VM 1, I run PuTTY with the IP address of VM 2 (10.0.0.3) and port number 22. I get prompted to input the username and password of VM 2 and everything works fine.From VM 2, I run on the terminal (Ubuntu): ssh [email protected] , I get prompted to enter the password of VM 1. I do so, but it says my password is invalid (while it is the correct one). I even deactived the Firewall on VM 1, but still the problem is here: my password is not accepted from VM 2. Is this due to some settings maybe I must do on VM 1 (Windows XP) so as I can access it with SSH ? Maybe it has something to do with the Firewall of Windows XP ?Important information: ping 10.0.0.2 from VM 1 and ping 10.0.0.3 from VM 2 are working successfully.

• The field for entering password freeze if no text is enter quickly after i install cinnamon on 12.04

  - by user109162

  Iam a total newbie to Ubuntu . I installed Cinnamon through terminal . The problem is that when i boot up, if i don't enter the password before 1 or 2 minutes the password field will freeze and won't accept any text inputs.The problem was most likely caused by Cinnamon because i guess the problem started after i tried to install some Cinnamon extensions. Please answer in non-technical way as far as possible. I will never go back to Windows whatever be the outcome. Help me stay on to Ubuntu.

• Ethernet Wired Connection Help

  - by user107598

  I have recently installed Ubuntu 12.10 onto my Dell Inspiron N5010 and Ive been all over many forums trying to figure out how I can get my ethernet cable to be recognized so I can set up a wired connection. My Network Card is the Realtek RT8139 and from what Ive gathered the ethernet port driver for it is installed. Whenever I run ifconfig in the terminal it says that eth1 is up and running but no matter how I edit the connection I cannot get it to work. If anyone can help it would be greatly appreciated!

• Can we grant sudo to an already opened application?

  - by james

  So, can we grant sudo to an already opened application ? I wish to first open an application as normal user and incase if i need root permissions on it i wish to grant su without restarting the application.. I tried opening an application and then type "sudo appname" in terminal, but that opens a new app window retaining normal user permissions on old app window. Say, i want to check and edit /etc/apt/sources.list . I open a filemanager and go to the path and click on sources.list which opens a text editor with that file in view. If i feel i need to edit that, then i want to grant sudo to that instance of text editor rather than opening a new root text editor and browsing the entire path.

• Compiz Error After Emerald Install

  - by KoopaTroopa

  Salutations! So, once again, I fell to the allure of the window decorator emerald. Where, just like the first time around, (I know I know) upon attempting to back out of emerald to the safety of compiz I'm faced with a problem. Seemingly after several minutes or after opening Chrome any window that isn't maximised has it's borders removed (so there's no close, minimise and maximise etc buttons). I can get them breifly back if I reload compiz via fusion-icon. After a brief chat on IRC it appears compiz is crashing. Here's a pastebin log of me running compiz via terminal. http://pastebin.com/sK65v4Fi I forgot my two vows of 'Never bother using Windows applications via wine or a VM' and 'Thou shalt never not use compiz'. ***GTK-Window-Decorator log gtk-window-decorator (gtk-window-decorator:11027): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap", Segmentation fault ** also posted on ubuntuforums to widen my scope of help.

• Cannot upgrade from Maverick

  - by Tideland

  When I attempt to upgrade the Update manager shows a warning message stating "Your ubuntu release is no longer supported." Okay... Click "close" it never goes away. Locks-up the update manager and game over. Next, try to update the software sources but can't do that either since it launches from the System Administer Software Sources and guess what? Needs sudo... But like all good linux software I'm sure the program is buried in a folder somewhere waiting for me to find it through the all powerful terminal program. Already commented out all Maverick Sources by hand but that didn't do the trick. Now what?

• No sound after clean install

  - by John Cheednik

  Did a clean install of Ubuntu 12.10 and everything working great except for the sound. Ubuntu doesn't even seem to be recognizing the fact my HP dv6000 has the capability of making sound! I have the dummy output problem, and when I try to open alsamixer using terminal I get the message that no such file or directory exists. I can't get it to recognize any soundcards or audio devices at all. I've been working on the problem for a couple days now and have even taken the laptop apart to ensure that all cables are properly attached... When I go into the PhoenixBIOS there are no sound options that I can find. The laptop does make a loud beep if I press buttons in the BIOS, but once it boots to the hard drive, the thing is mute. HELP!

• Error installing gPodder

  - by Ron Webb

  A few weeks ago (newbie alert!) I started using XUbuntu 12.04 with Xfce 4.8. I'm trying to install gPodder Podcast Client (see https://launchpad.net/~thp/+archive/gpodder). I've added the PPA via terminal commands as instructed. When I click the Install button in the Ubuntu Software Centre I get the following error: Package dependencies cannot be resolved This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time. Details: The following packages have unmet dependencies: gpodder: Depends: python-webkit but it is not going to be installed What do I need to do? Just to make thing more complicated -- I'm not sure, but before I found the launchpad.net link, I think I may have tried to install gPodder from the default Ubuntu repositories (also unsuccessfully). There may be remnants of the previous attempt still installed, which may be blocking the new install. Where/how can I find them?

• Script for Creating Multiple ZIP archives from Multiple Folders

  - by user39288

  I want to be able to right click multiple folders inside of a directory in nautilus, and be able to create seperate zip archives from those folders in that same directory. If possible it would also be great if it automatically deleted the old folders. So, if I have 30 folders, I want to select those using control-shift, then go to scripts and run the script, and just have those 30 folders compressed into seperate .zip archives, and have the old folders deleted (if possible). Anyone know how to accomplish this? I suck with terminal, and am looking for a script solution.

• Software center crashing in 12.04

  - by Jordan

  i'm having issues with the Software Center. I'm trying to install Google Chrome, but can't because the software center crashes as soon as it opens. I've looked around at similar topics and found plenty but none of the suggested solutions have worked, so I wonder if this is different. When I type 'software-center' into the terminal, I get the error that other's have had: softwarecenter.backend.reviews - WARNING - Could not get usefulness from server, no username in config file I know this might seem like a duplicate, but none of the solution worked. Sorry, kind of new to Ubuntu. I use Ubuntu 12.04 lts

• Ubuntu 12.04 very slow on samsung netbook

  - by vallllll

  I have a samsung netbook n150 1Gb Ram (Intel graphic card), 1,66GHz Intel Atom processor. It was working great with the ubuntu 10.04 netbook edition, really fast boot very eficient but I have updated to 12.04 (the netbook edition doesn't exist anymore) and now the system is so slow: slow boot, sometimes it doesn't even boot properly, strange screen light on and off behaviour, when you click on an icon takes for ever to open the app even the terminal it takes like more than 10s! It seems that this new distro was made for a far more powerful systems than this netbook. I am considering to revert back to 10.04 or choose another linux distro but is there anythhing i can do to fix these problems? Any body else had similar problems. Thanks in advance

• Can't install ATI proprietary drivers in 12.10. Unity is Missing

  - by EApubs

  I have a laptop with ATI Radeon 6770M HD Hybrid graphics card. In Ubuntu 12.04, I installed the fglrx driver through "additional drivers" and it worked. (I can even switch GPUs). But in the new Ubuntu 12.10, after installing, Unity won't load. Only the mouse and the wallpaper. If I initialize the settings sudo aticonfig --initial then after rebooting it gives a warning saying I'm in low graphics mode! How to fix this? PS : Earlier i used software source to install the drivers. But when using the terminal, I got this warning : update-alternatives: warning: forcing reinstallation of alternative /usr/lib/fglrx/ld.so.conf because link group x86_64-linux-gnu_gl_conf is broken Update : Filed a bug report in launchpad : https://bugs.launchpad.net/fglrx/+bug/1068661

• ubuntu-overlay-scrollbars set to false shows no arrows in several cases

  - by Willem van Gerven

  I'm running 12.04, and prefer the more conservative style "normal" scrollbars over the overlay scrollbars. I have set them to false in the terminal: gsettings set org.gnome.desktop.interface ubuntu-overlay-scrollbars false However after doing so, with some apps (e.g. Nautilus, Document Viewer) my scrollbars only view a vertical bar, but no arrows on the top and bottom to scroll up and down. With some programs these are shown though, for instance Gummi and Texmaker. It would make a big difference (for instance when having to scroll pdf documents containing several hundreds of pages) to have those arrows reinstated. Is there any way to make this work?
