• How safe is ubuntu?

  - by VJo

  Last week I started desktop sharing using krfb. Since I continue last session, this program keep on starting again. Two days ago I noticed messages poping up saying something like "rejecting uninvited connection from (some ip)", but today I figured it might be because of this and I was right. The krfb was running in the background. Hence the question. How safe is ubuntu? Should I expect someone to connect to my computer and erase everything I got on disk? EDIT To extend my question : how safe it is comparing to other OSs (windows, mac,...)? How safe it is comparing to other distros?

• Is it okay for an application to check for automatic updates in less than 20 hour interval?

  - by FlameStream

  I have a desktop application that has the ability to automatically update itself on the next restart (without the user's consent - but this is another issue altogether). Assuming that the user would never notice anything related to application updating (such as a progress bar, or pop-up requiring restart), and that our server would support the request spam load, is there any reason why it should not check for updates in less than 20 hour interval? The reason I'm asking this is because all applications that I know that have auto-update capability check for update every 20 to 24 hours and at startup. I was just wondering if there was an ethical rule about it, or simply because of the risk of overloading the server.

• Why am I missing the Ubuntu icon on the log-in screen?

  - by dtdlurch

  I am running Ubuntu 12.10. On the log-in screen, there is no Ubuntu icon for me to click on to change desktop environments. I know where it should be, but it is simply not there. Why is this? And how can I get it back??? I just installed Cinnamon and I would very much like to switch to this environment. I apologize if this is has been addressed elsewhere, but I honestly did try to research before asking. I found several similar questions, but nothing that has answers that helped my situation. And an hour of Googling did not produce anything helpful at all. Thank you for your help.

• Garbled screen after sleep/suspend with nVidia 8800M GTS Ubuntu 11.10

  - by user34062

  Just did a clean install of 11.10, have been using it (and enjoying it!) for about a day now. But it seems that every time I resume from a sleep or blank screen after idling for a while, my desktop, as well as any programs on the screen get "garbled" I had a few windows open and all displayed the same gui glitching except for Chromium (I am guessing because it was minimized to the Unity Launcher, and not currently on the screen when I woke the PC up.) Anyone know what might be causing this, and how I might be able to fix it? I am using a Gateway P-6860FX with a C2D 1.8GHz, and nVidia 8800M GTS 512mb. Screenshot: http://dl.dropbox.com/u/28188839/Screenshot%20at%202011-11-15%2018%3A53%3A25.png NOTE: Yes, I know I misspelled Lothlorien.... .<

• How to effectively draw on desktop in C#?

  - by Lazlo

  I want to draw directly on the desktop in C#. From searching a bit, I ended up using a Graphics object from the Desktop HDC (null). Then, I painted normally using this Graphics object. The problem is that my shapes get lost when any part of the screen is redrawn. I tried a While loop, but it actually ends up drawing as fast as the application can, which is not the update rate of the desktop. Normally, I would need to put my drawing code in a "OnPaint" event, but such thing does not exist for the desktop. How would I do it? Example code: http://stackoverflow.com/questions/1536141/how-to-draw-directly-on-the-windows-desktop-c

• Should I get a desktop PC if I will move abroad

  - by alex

  Hello, This is probably a bit of a personal opinion style question - should I buy a desktop or a laptop? Generally I would prefer a desktop, since it's generally cheaper for the same specs, but it's about 50% likely that I will have to move to Japan (from UK) for a couple of years in two years or so. I have never heard of anyone travelling with a desktop - is it even possible without getting it destroyed? If anyone have experience in this area, could you suggest me if It's better to choose a laptop just for this reason? I don't really care about mobility on daily basis that much as I already have a netbook. Thanks for all the help and sorry if it's a bit off topic.

• Free desktop recording / screencasting on windows

  - by Mercer Traieste

  I'm a newbie in desktop recording and screencasting. I didn't find a suitable free application to do all the things I want it to do, but I did enjoy using jing. I would expect such an application to have these features: choose the whole desktop, a region, a window to record zoom in an area, and camera move save the recorded movie to a compressed format have basic editing tools have the mouse highlighting feature (either a sonar blip or something similar) highlight window/field on the screen, any trick will do display pressed keys/key combinations (like iphone does) So the question is: Which free desktop recording/screencasting software would you recommend on windows? It doesn't have to have all those features, just tell me your favorable experiences. Please suggest tools that would do mouse/keys/areas highlight tricks. I'm open to commercial software too, but I would prefer a free one. Thank you!

• Windows 7: Open File - Security Warning box appears for every app on the desktop

  - by Michael Ratanapintha

  Whenever I double-click to open an executable on the desktop (.exe, .bat, etc.), or a shortcut on the desktop that points to an executable, the "Security Warning" pops up and asks me "Are you really sure you want to open that? Stuff from the Internet is dangerous!" I don't usually mind this warning and don't want to disable it globally, but now I'm getting it for any executable on the desktop, even ones that I didn't download from the Web and don't have the Mark of the Web alternate data stream. (That is, streams -d * shouldn't and doesn't help.) This started fairly recently, but I can't really point to anything I did that triggered it. It only occurs in one user account on the machine; the other account doesn't have this problem. Running System Restore didn't help. How can I fix the problem and make the pop-up warning appear only when it's supposed to?

• How does Windows Remote Desktop Connection Work?

  - by Devoted

  How does Windows Remote Desktop connection work? An IP address is used to connect to the computer but....how can that IP be accessed from anywhere? If, for example, the IP address is 128.10.10.10, there MUST be another 128.10.10.10 somewhere else in the world. How does Remote Desktop know which one to connect to? Thanks so much EDIT: Thank you! Answers cleared this up quite a bit. But if my remote desktop connection suddenly stopped working and I didn't change anything, how do I even start to diagnose what may be the problem? I can remote connect to it from a LAN computer though...

• Notepad Automatically Launches Upon Boot Up of my Windows 7 64-Bit Desktop PC

  - by Simon

  Around 12 months ago, When my Windows 7 PC boots up, Notepad started to appear automatically on the desktop (as a duplicate ie one on top of the other), both displaying the same writing inside, and the name of the Notepad was: desktop-Notepad. [.ShellClassInfo] LocalizedResourceName=@%SystemRoot%\system32\shell32.dll,-21787 I cant remember the exact details as its been so long now but a friend told me, this was due to a "hidden attribute" belonging to notepad becoming "unhidden"and therefore showing itself on the desktop at startup. He showed me a series of steps to either hide the attribute again or to delete it ( telling me that upon restart of my computer it would be recreated/regenerated.) I did indeed follow his guidance however after trying to hide it or delete it (it was never recreated after restart which supposedly it should have done) One notepad still is autolaunched with the text as shown above everytime I startup my PC. As I found this forum I thought I might try again for a solution to prevent notepad from launching. Thankyou

• What is the best software for desktop recording?

  - by Ivo Flipse

  I know this question is partially a stub from: http://superuser.com/questions/201/free-desktop-recording-screencasting-on-windows However I would have to use this at work, so it doesn't have to be free, just work very well.

• What's wrong with my custom .desktop xsession?

  - by Noam Gagliardi

  I want to create a custom Xmonad session that loads an .xsession script in my home folder. This is the original file I copied. This one works: [Desktop Entry] Encoding=UTF-8 Name=XMonad Comment=Lightweight tiling window manager Exec=xmonad Icon=xmonad.png Type=XSession This is my modified file, xmonad-custom.desktop. When I logout, then login choosing this "xmonad-custom", the screen just flashes and sends me back to the ubuntu login screen (as if it briefly logs in and out of the session): [Desktop Entry] Encoding=UTF-8 Name=XMonad Custom Comment=Lightweight tiling window manager Exec=/home/{username}/.xsession Icon=xmonad.png Type=XSession X-Ubuntu-Gettext-Domain=gdm I also tried without the last line. This is my ~/.xsession file, in case there's an error with this script: #!/bin/env bash xrdb -merge .Xresources trayer --edge top --align right --SetDockType true --SetPartialStrut \ true --expand true --width 15 --height 12 --transparent true --tint 0x000000 & dropbox start & exec xmonad

• Windows 7 Computer Maintenance - Restore removed Desktop Shortcuts

  - by HaydnWVN

  I'm aware about the inbuilt nightmate 'tool' of Microsofts which is making every network administrators job a nightmare (if left turned on). In short it'll happily delete every desktop shortcut to a network resource. We have it disabled by default. My question is related to recovering these shortcuts, Windows doesn't seem to dump them into the Recycle Bin and although you can 'restore previous versions' of the Desktop folder, you are unable to do it with the user logged in... Rather a problem if you only have the 1 user account. We have a user who (although the 'Computer Maintenance' tool is turned off) had it come up in 'Action Centre' and chose to run it. I've been unable to reproduce it, but the tool has certainly run (and removed 24 shortcuts from her desktop) although it is still saying 'Windows is not checking your system for maintenance problems'. ?! Very fustrating! Any ideas if these shortcuts are backed up/moved elsewhere so i can easily find and restore them?

• Laptop connected to external monitor results in desktop overflow

  - by Andrew Fox

  I have a laptop (MSi FX600) connected to an external monitor (Toshiba 19AV500U) with the screen resolution set to the monitors recommended setting of 1440x900. The problem is the desktop is overflowing the display, meaning all edges of the desktop are cut off, so I cannot see the close, minimize buttons on the top and I only see half of the taskbar at the bottom. I have tried many different resolutions but none of them solve the problem. I have had this same problem when connecting to other external monitors in the past, but not all of them, it seems to be fairly random. I have tried to find a way to manually adjust the resolution but I cannot see a way to do this in my settings. All windows updates are up to date, I am connecting through an HDMI cable and I have it set to display only on the external monitor and not extended desktop.

• Files and folders disappeared from my desktop

  - by Rob

  Suddenly all files, folders and icons that were on my desktop have disappeared. tried making "show hidden files", no luck. tried using recovery software, but it did not find any of this files, so I assume they were not deletes. c:/Users/<myname>/Desktop does look empty from the Explorer, as well as from cmd. installed MalwareBytes, it did find and remove some malware, but it didn't seem to help. used RogueKiller and it did find some suspicious registry called "HideDesktopIcons". ¤¤¤ Registry Entries : 4 ¤¤¤ [HJ DESK] HKCU\[...]\ClassicStartMenu : {59031A47-3F72-44A7-89C5-5595FE6B30EE} (1) -> REPLACED (0) [HJ DESK] HKCU\[...]\NewStartPanel : {59031A47-3F72-44A7-89C5-5595FE6B30EE} (1) -> REPLACED (0) [HJ DESK] HKCU\[...]\ClassicStartMenu : {20D04FE0-3AEA-1069-A2D8-08002B30309D} (1) -> REPLACED (0) [HJ DESK] HKCU\[...]\NewStartPanel : {20D04FE0-3AEA-1069-A2D8-08002B30309D} (1) -> REPLACED (0) I deleted this registry, rebooted, it only unhid My Computer and User icons, but my desktop stuff is still missing — any ideas what should I do next?

• Redirect audio from laptop to desktop over LAN

  - by Ram Rachum

  I want to be able to play a song on my laptop and have it sound through my desktop's (infinitely better) speakers. If you're familiar with Input Director: I want something that is to audio what Input Director is to mouse/keyboard. I want something that automatically redirects all audio from the laptop to the desktop in real time, and I want that solution to require, like Input Director, minimum maintenance. Beyond the initial setup, I don't want to have to babysit the program that does this. I want something that launches automatically with Windows and just works, and also allows me to cancel it whenever I want. And also doesn't go crazy when the laptop is turned on in a different network where the desktop computer isn't available. Any suggestions for such a program? (I use Windows XP on both computers.)

• use correct-resolution background desktop image

  - by Rob Bos

  I have a desktop background image (a picture) in a half-dozen different resolutions, that I'd like to deploy to a disparate collection of computers with different monitors and video cards and whatnot. Laptops, netbooks, desktops, widescreen, and even a couple of "tall" screens. I have images to cover most of the cases. I would like Windows 7 to correctly pick the correct desktop background image via group policy. Now, the logon screen is already done. The OEMBackground method is rather clever, and lets you copy files of different resolutions to the machine, and the logon app will calculate the aspect ratio of the monitor and match it to a file as closely as possible. Is there any way to have that functionality on the desktop background as well?

• Why is Desktop Unity using the global application menu?

  - by Kazade

  It was announced in another question that the desktop version of Unity will keep the global menu by default. Here are the facts: The global menu was introduced into UNE to save vertical screen space because at Netbook resolutions the vertical space is limited. On a modern desktop with a high resolution, there is ample vertical space making this unnecessary On the announcement of UNE global menus, Mark Shuttleworth himself said the following: "There are outstanding questions about the usability of a panel-hosted menu on much larger screens, where the window and the menu could be very far apart." The benefits of a global menu don't seem to carry across to a high-resolution desktop and instead seem to bring draw backs (increased mouse travel, large distance between the menu and its associated window). The other worrying factor is that applications seem to be moving away from having a menu bar, and instead of innovating on this and defining new guidelines for moving away from the menu, we are giving it prime place right at the top of the desktop. If applications continue moving away from the desktop we will have an inconsistent experience concerning where to locate application related options/tools depending on which app you are using (e.g. Chrome). Finally, the current global menu bar implementation doesn't work for all apps, and doesn't even work for all apps in the default install. This means that the default desktop implementation will be inconsistent. So, there are a bunch of reasons why moving to a global menu is a bad idea, so we need some pretty convincing arguments for why it is a good idea. What are the reasons for the global menu implementation in the desktop version of Unity?

• cups log kills ubuntu 12.04 and sudoer permissions changed

  I am using Ubuntu 12.04 as a desktop and recently had a weird crash with the log file for cups filling up the entire drive and not letting me back in, also what changed was /var/lib/sudo had changed from root to peter (me) I didn't make this change - I checked the history! I set the sudoers back to root and capped the max size for cups log Anyone had a similar experience?

• how to delete multiple folders,desktop and start menu shortcut using vbscript

  - by user1756858

  I never did any vbscript before, so i don't know if my question is very easy one. Following is the flow of steps that has to be done : Check if exist and delete a folder at c:\test1 if found and continue. If not found continue. Check if exist and delete a folder at c:\programfiles\test2 if found and continue. If not found continue. Check if a desktop shortcut and start menu shortcut exist and delete if found. If not exit. I could delete 2 folders with the following code: strPath1 = "C:\test1" strPath1 = "C:\test1" DeleteFolder strPath1 DeleteFolder strPath1 Function DeleteFolder(strFolderPath1) Dim objFSO, objFolder Set objFSO = CreateObject ("Scripting.FileSystemObject") If objFSO.FolderExists(strFolderPath) Then objFSO.DeleteFolder strFolderPath, True End If Set objFSO = Nothing But i need to run one script to delete 2 folders in different paths, 2 shortcuts one in start menu and one on desktop. I was experimenting with this code to delete the shortcut on my desktop: Dim WSHShell, DesktopPath Set WSHShell = WScript.CreateObject("WScript.Shell") DesktopPath = WSHShell.SpecialFolders("Desktop") on error resume next Icon = DesktopPath & "\sample.txt" Set fs = CreateObject("Scripting.FileSystemObject") Set A = fs.GetFile(Icon) A.Delete WScript.Quit It works fine for txt file on desktop, but how do i delete a shortcut for an application from desktop as well as start menu.

• How To Auto Add To /etc/resolv.conf?

  - by Volomike

  On Ubuntu 10.04 Server, you can edit a file and it will automatically add a nameserver to the /etc/resolv.conf on boot. Unfortunately, Ubuntu 10.04 Desktop does not have this feature that I'm aware of, although perhaps I could be wrong. See, as a web developer, I replace my localhost domain with "me.com" (since I never use me.com) in my /etc/hosts file. So, I can visit my own web server this way. But since my /etc/resolv.conf doesn't have nameserver 127.0.0.1 in it, every lookup has to go out to my slow ISP DNS lookup and then back. So, I edit the file manually, but every time I reboot, the connection gets lost, and every time my ISP has troubles and my system renegotiates afterwards, I have to type this entry in again. Oh, and I prefer that the nameserver 127.0.0.1 be first, not last. Note without this entry, every connection to me.com is slow. With this entry, my connection to me.com is super fast. Is there a way to automatically do this on boot?

• How to get a Sun Ray to load a firmware from elsewhere

  - by vdiozguy

  I run a Sun Ray/VDI demo environment internally within the company - and because it's not a public service, I need to tell my Sun Rays to connect to it directly so that I don't get redirected to the corporate servers. To get any new Sun Ray to connect to *my* setup I usually pull out my laptop so that the Sun Ray can load the new version of the F/W along with the permission to pull up the management GUI via STOP-S.But there is a better way if you have another Sun Ray server handy:1) allow your Sun Ray to connect to the default corporate server2) log in to a "regular" session, that is a Solaris or Linux desktop on the Sun Ray server itself3) in a terminal, utswitch to your server (/opt/SUNWut/bin/utswitch -h myserver)4) again, login to a regular session there5) in a terminal,  issue "/opt/SUNWut/lib/utload -S myserver -w"6) Watch your firmware load and wait7) the Sun Ray will reboot and connect to the first server again. Repeat steps 2-48) issue "/opt/SUNWut/lib/utload -S myserver -f SunRay.enableGUI"9) Press STOP-S and be merryNOTE: I'm sure there is even yet a better way - this is totally unsupported, most likely a figment of my imagination. In any case, this post will self-destruct in BOOM.

• Ubuntu won't boot after initializing the Build Environment for Android

  - by EntryLevelDev

  My laptop worked perfectly util I initialized the build environment for Android. The GUI won't start. It looks like some kinds of graphics card problems. I tried to fix it but after trying a lot of solutions on the internet nothing worked. (I only know basic linux stuffs.) I've already reinstalled the OS. However, I still want to build the Android from source. Any idea what might cause the problem? any workaround? Here is the command that I used to initialize the build environment: $ sudo apt-get install git gnupg flex bison gperf build-essential \ zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \ libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 \ libgl1-mesa-dev g++-multilib mingw32 tofrodos \ python-markdown libxml2-utils xsltproc zlib1g-dev:i386 $ sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so My laptop model is asus u36sd. (https://help.ubuntu.com/community/Asus_U36SD) Thanks Edit: Base on this, I guess libgl1-mesa-glx:i386 might cause the issue. sudo apt-get install libgl1-mesa-dri:i386 The following packages will be REMOVED: libgl1-mesa-dri-lts-quantal libxatracker1-lts-quantal ubuntu-desktop xorg xserver-xorg-lts-quantal xserver-xorg-video-all-lts-quantal xserver-xorg-video-vmware-lts-quantal The following NEW packages will be installed: libdrm-intel1:i386 libdrm-nouveau1a:i386 libdrm-radeon1:i386 libdrm2:i386 libexpat1:i386 libffi6:i386 libgl1-mesa-dri:i386 libllvm3.0:i386 libpciaccess0:i386 libstdc++6:i386
