• Never before had a problem with Ubuntu desktop graphical display; Trying to use nvidia GT630

  - by focaccio

  I've been using ubuntu since 9.04 and never had a problem with Ubuntu brining up the desktop graphical user interface. However I am currently not able to see anything graphical past the install screens. I have an Intel DP55KG motherboard and just installed an nvidia gt630 graphics card (zotac), since the old graphics card failed. I can install the server and see text. So I do a apt-get install ubuntu-desktop...or apt-get install kubuntu-desktop...or apt-get install xubuntu desktop, but after the reboot there is no display...its like something is hung up. I tried using the Live quantal dvd and I do see the graphical prompt to try without installing, but after that the screen goes blank. I've tried two monitors and the same thing happens. There is a faint "glow" on the screen and I do not get a "no input signal" from the monitor, so something is happening. I can install an old OEM of XP so I know the video card and motherboard are at least semi functional. Any help is appreciated. Thanks, Greg

• Java desktop programmer starting to learn Android development: how different is it?

  - by Prog

  I'm a Java programmer. All of my experience is on desktop applications, using Swing for the GUI. I spend a lot of time studying OOP, I have decent understanding of OO concepts and I design and program by the OO approach. I'm thinking of starting to learn Android development soon, and I'm wondering how different it is from desktop development. Obviously the GUI libraries will be different (not Swing), but other than that, I want to know if there are significant differences. I will divide this question to two parts: Apart from the GUI libraries, am I still going to use the standard Java libarary I'm used to? Aka same data structues, same utility classes, etc.? If not, what are the main differences between the libraries I'm used to and the libraries I'll be using? How different is Android development in regard to OO design? Are all of the familiar principles, design patterns, techniques and best pratices just as valid and used? Or is OOP and OOD in Android development significantly different than OO in desktop development? To summarize: apart from GUI design, how different is Java Android development than Java desktop development?

• Remote desktop connection to network printer

  - by andand

  I'm trying to print a document from a remote WinXP machine to a network printer I use on a local Win7 machine using Remote Desktop. The network printer does not appear in the list of those available on the WinXP box. In more detail, the local machine runs Windows 7 (no admin rights) and connects to a network printer managed by a print server (i.e. not using a local TCP/IP Port). I have access to a Windows XP host on a separate network which I access using Remote Desktop. I would like to have print requests from the remote XP box forwarded to the network printer I use on the Windows 7 machine. The XP machine cannot access the print server I use on the Win7 machine nor can it create a TCP/IP port to connect directly to the printer (network configuration issues). After having consulting the KB312135 I confirmed the "Printers" option was selected in the Remote Desktop Client, Local Resources Tab, yet the network printer does not appear on the list of available printers on the XP box. Is this a lost cause or is there something else I haven't managed to locate yet?

• Remote Desktop connection to vista vs. xp

  - by CMP

  I am trying to log into my work computer remotely. I am using Windows 7 on my laptop. I have created a vpn connection to the network, and I am doing a remote desktop connection directly to the ip of my box (192.168.xxx.yyy). If I do a remote connection to a different box, running xp, it goes into remote desktop mode immediately and I see the windows login dialog as I am used to seeing. If I try remoting to my box, which is running vista, I do not see the remote desktop mode, but an additional dialog on my local machine asking for my credentials. It defaults in my local username. It allows me to log in as a different user, but the domain it has is still my local domain, not my work domain, so none of my usernames or passwords work. There doesn't appear to be a way to change the domain. Trying to hit several more boxes, it appears to act differently on xp and vista target machines. I feel like this must be a configuration issue, but I am not sure what the problem is. Any idea on how I can connect?

• Import virtualBox appliance to KVM

  - by Hugo Bulnes

  Im new using KVM as a virtualization solution. Currently I'm using VirtualBox to manage my virtual machines in my personal computer, but I'm moving my virtualization to a Server, so I set up a Linux server with KVM. And now I'm trying to import a virtualBox vm to KVM. So far I couldn't make it work. I already convert the ova file from VirtualBox to a format more familiar to KVM (qcow2), and I try to create a new virtual machine using virt-install command and setting the new virtual machine hard drive with the .qcow2 file. There is anyone could help me? thank you!

• How can an experienced web developer transition to desktop development?

  - by Craige

  I'm a web developer, first and foremost. I've been programming for 5 or 6 years now, all of which has been web-based. I'm good at my job, both specifically as a web developer and as a programmer in general. I have decided recently that I would like to learn some desktop programming to to beef up my skill-set. My question is this: How can an experienced web developer transition to desktop development? To elaborate: I have always been a web-developer, and I can design and build web-applications without any problem. When it comes to sitting down with a to learn some desktop oriented programming, my problem isn't with any of the technical matters, but rather coming up with an idea to program. I draw a blank.

  My problem is, that i do want to create a .desktop file for Technic Launcher, which is an alternative launcher for Minecraft. It comes in the form of an .jar file and i want to create a menu entry for it. How would i write such a .desktop file?

• How to tweak the appearance of desktop icons in Lubuntu?

  - by vasa1

  In Ubuntu 11.10 with Nautilus it was possible to tweak the appearance of desktop icons by editing nautilus.css as I had posted in How can I change the text colour on my desktop icons?. In Xubuntu the same can be done by adding a few lines to one's .gtkrc-2.0 as described in How to highlight items on Desktop using xfce?. In both cases, it is possible to assign colors to the various icon states (such as normal, selected and active). My question is this: is it possible to do the same in Lubuntu? PCManFM seems to be responsible but I can't find any GUI or files to edit for the purpose. The default ~/.config/pcmanfm/lubuntu/pcmanfm.conf doesn't have any relevant settings.

• Can't right click, copy or move files to Desktop???

  - by user1698774

  I am on Ubuntu 12.04 running gnome shell 3. Everything worked fine until I updated just a few hours ago using the update package. First my default shortcuts stopped working, fixed it by creating custom ones. Now while on the desktop I can't right-click, move files to it or see the files that were there previously. However, in terminal I can navigate fine to Desktop and my files are there, except not visually on the desktop. Permissions are all set correctly. Please help. Thank you.

• Wastage of resources in Virtualization

  - by Sabeen Malik

  I am not sure if this is the write place to ask the question. However i hope it is. When looking for a VPS earlier today, I was trying to understand how each container would work in the background. Keeping in mind the fact that the operating system uses most of the power and power on a system, wouldn't having multiple operating systems in the same machine mean more wastage of resources. For instance if i was running centOS on a dedicated box and it was running lets say 20 background OS level processes. Then i go and install a virtualization platform and install 5 more centOS virtual machines in the same system which are exactly the same as the host operating system. Doesn't this mean duplication of those 20 processes 6 times? So internally the context switching is happening between 120 processes instead of 20?

• remote desktop client with panning of large desktops?

  - by mikewse

  When using the standard Windows remote desktop client to connect to a large remote desktop, the result is usually that the remote desktop is resized to a smaller size matching the local display. Are there any RDP clients that instead leave the remote desktop at its original size and pan this larger area when the mouse reaches the border edges of the local display? Thanks Mike

• Virtual PC on Windows 7 - Hardware-assisted virtualization is disabled

  - by DLux

  I am running a Lenovo Thinkpad T61 with an Intel Core 2 Duo T7300 processor. When I run Virtual PC in Windows 7, I get the following error: Unable to start Windows Virtual PC because hardware-assisted virtualization is disabled. When running the Hardware-Assisted Virtualization Detection Tool from Microsoft says: Hardware-assited virtualization is not enabled on this computer. Now, in the BIOS, I do have virtualization enabled and according to Intel this processor supports Intel-VT. What am I missing here?

• Tunneling a TCP/IP Connection through Remote Desktop Connection

  - by Kristopher Johnson

  There is a remote Windows server on a private network which I can connect to via Remote Desktop Connection. I would like to be able to make TCP/IP connections from my computer to other computers on that server's network. Remote Desktop Connection makes it possible to share printers, drives, and other local resources through the connection. Is there any way to "tunnel" a TCP/IP connection via RDC? I'd like something similar to the port-forwarding provided by SSH. I don't see any way to do this via RDC, but I'm hoping the capability is there and I just don't know about it.

• Remote Desktop, Host: 2008, Client: Windows 7, The remote computer requires Network Level Authentica

  - by deerchao

  Hi, today I accidently changed one option of Teminal Services, I checked "Allow connections only from computers running Remote Desktop with Network Level Authentication". After that, I can't connect to my server any more. The error says: The remote computer requires Network Level Authentication, which your computer does not support. But my client pcs(both home and at office) are running Windows 7, as far as I know, it shoud support NLA; And in About dialog of Remote Desktop Connection there says "Supports Network Level Authentication". My server is running Windows Server 2008, placed in IDC center; I could connect to it before I change the settings. All other sevices(like IIS, SQL Server) are running normally. For clients, I tried two PCs running Windows 7, and two virtual windows XP machine running in Virtual PC and Virtual Box, all of them gives the same error message. Is there a way I can make things right without go to IDC which is far away? Thanks.

• Trouble using remote desktop when connected via Cisco VPN

  - by Kyle B.

  I just setup my Cisco VPN and everything appears to be working fine. I opened the 'remote desktop' application and am unable to connect to my work desktop machine. When I disable Windows Firewall, I am able to connect, but not when Firewall is enabled. Is there a specific settings inside Windows 7 Firewall that should I be enabling or disabling for this to work without having to shut down the entire system? I can post this in superuser.com instead if you feel it belongs there, but posted here due to it being related to VPN and Firewall. Thanks, Kyle

• The difference between desktop-series HDD drives and server-series

  - by FractalizeR

  Hello. What are the main differences between desktop-series hard disks and server-series? The obvious things I can see are: durability (server hardware mostly more qualitative and have more warranty) and power consumption (server hardware more focused on performance, than on power economy). Also server disks are usually a little faster, but it seems, that it is not always the case. May be there are some other reasons, that make you choose server-oriented series (Seagate ES drives, for example) over desktop-oriented ones (Seagate Barracuda series)? What are they?

• Mysterious gray square outlines on certain desktop icons?

  - by user74757

  Recently, my hand slipped on my mouse/keyboard and I accidentally increased the icon size. After resetting it and fixing them, I noticed these incredibly annoying small gray outlines around only certain desktop icons. I have one third party program called 'Desktop Restore' that I use to save and restore icon layouts, but I have no reason to believe that it should have anything to do with it. My question is: Is this something in Windows 7? If so, what is it there for and how can I turn it off? Killing explorer.exe and restarting it doesn't fix the problem, not even rebooting...

• User profile and desktop unclickable and unviewable from windows explorer

  - by Abel

  Situation: Windows Vista, latest updates. After restarting to complete an installation, I find myself looking at a totally black windows desktop without any icons. The start menu and taskbar, including quickstart icons, appears. Some, but not all task bar tray icons appear. The systems seems stable. When I open Windows Explorer and click "desktop" in the folder treeview, the cursor immediately jumps back to the previously selected item. No error. Same when clicking on my user's profile or my documents. When I try "save as" in, say, Notepad, nothing happens, the dialog box (which defaults to "my documents") doesn't even show. Again, no error. Nothing serious afaict in the event log. Typing something Start Search shows "Search failed to initialize". Anybody ever encountered such abomination?

• Windows 8 Pro Remote Desktop issue

  - by Mike C.

  I have a weird issue here. I'm running Windows 8 Pro. The client computer is also running Windows 8 Pro. Remote Desktop works when I'm in the same network. I tried connecting using my external IP Address and my DynDNS account, neither works. I disabled Windows Firewall and setup DMZ for my computer on the router, still can't get remote desktop to work. I verified www.canyouseeme.org, port 3389 is open, which is obvious since I'm running DMZ! My ISP, Bell Canada (modem/router: Sagemcom F@st 2864), blocks port 80 and 25, but I don't need those for RDP, do I? The funny thing is RDP rejects the connection instantaneously for my IP or DynDNS while it takes a while for another address. Thank you, Michael

• Remote Desktop to Virtual Machine

  - by Valvaris

  Hello: I recently reformatted one of my servers with Windows Server 2008 x64 and with that, installed the latest version of VMWare server on it. Within that, I created a new Windows Server 2003 R2 x86 virtual machine for the purposes of being a backup domain controller. I was able to successfully configure it as a domain controller and have it provide DNS service to my domain. I've been using the VMWare remote console to set this up and figured it was time to get remote desktop working. I set it up as I have with many other computers on my network (hitting the checkbox, making the firewall isn't blocking it) and I cannot get remote desktop to connect to it. I've tried using the computer name and its IP address neither work. I can ping the computer from the outside but the Virtual machine cannot ping anything from inside it. All machines are on the same subnet. I can't seem to figure this out.

• Bringing Google Docs to the Desktop.

  - by Jonathan Sampson

  Is there a stable way of accessing Google Docs (application) from my desktop without having to use a browser on Windows? On my accepted answer... While I did stipulate that I wanted to not use my browser, I didn't really mean I wanted to avoid browser technology. I meant I didn't want to open my browser, type in the web address for google docs, etc. TheTXI's answer required me to download/install nothing more than what I already had (Chrome) to acheive this. It created a desktop icon (similar to an application) that launches me right into my docs (similar to an application), without extra browser-items on the screen. This was an excellent suggestion, and won by virtue of parsimony.

• Remote desktop use two out of four monitors

  - by William Gant

  I've recently upgraded my home workstation and now have four monitors on it. I work remotely most of the time and need some way to get remote desktop onto only two of those four monitors. The top two monitors (monitors 4 & 3, going from left to right) each have a maximum resolution of 1680x1050. The bottom two monitors (1 & 2) each have a maximum resolution of 1920x1080. In my .rpd file for this remote desktop connection, I have the following keys (I've clipped it for brevity) screen mode id:i:2 use multimon:i:1 desktopwidth:i:1920 desktopheight:i:2130 session bpp:i:32 winposstr:s:0,1,3,75,1655,675 Previously I was able to get away with just doing "mstsc /span" when I had only two monitors, but that isn't working now (and isn't desirable). I'd like for the new setup to only use two of my monitors. I don't really care which two. How do I alter the .rdp file to accomplish this?
