• Missing resolutions on ubuntu 11.10 fresh install

  - by Sean Marshall

  Today I installed Ubuntu 11.10 for the first time on my computer. My Monitor's resolution is 1280x1024, but the only resolutions in display are "1024x768 (4:3)" and "800x600 (4:3)". I installed all updates, There is nothing in additional drivers and still nothing. I want to set the resolution to 1280x1024. How do I check my graphic card name? By the way Unity 3d is working and compiz effects are working super fast.

• Printer Sharing Issue

  - by Sean Webber

  So I set up my printer on 12.10 to share via SAMBA. Windows 'sees' it, it will install it on windows (I have the printer driver installs but it asks for it in Windows default list.. ?), then I can print a test page to the ubuntu printer from Windows. But If I try to print something in Notepad/Wordpad it says 'Printing' but doesn't add it to the "See whats printing" list. If you do it in Google Chrome, however, it works. Any ideas?

• Ghosting Program for Ubuntu 12.10

  - by Sean Webber

  I am looking to figure out how to set up a mass backup system for a computer network (of about 25) and am looking for a ghosting program that makes an image of the entire system for backup/recovery purposes. While clonezilla would work.. you have to manually boot us the CD for it. I am looking for a program that runs INSIDE Ubuntu that sends a system image backup off to the network server at set times, then when needed could also be used to burn the clone back to the machine. Another words- automatically and the only time I have to do anything to it is when I need to burn a backup BACK to a 'crapped' machine. Any ideas?

• Ubuntu 12.10 WiFi Problems

  - by Sean Webber

  I have a 32 bit machine running Ubuntu 12.10 with WiFi on it. I have a WPA2 network at home, but if I leave the USB Adapter plugged in while it boots, it infinitely keeps asking for the network password but never connects. If I plug it in after boot, it will connect but then I can't access ANYTHING on the LAN or Internet because "the DNS servers are unreachable". Now, if I leave the computer on a while, I get lucky sometimes and it MAGICALLY decides to connect for a little bit, lock the machine though and the Internet's gone again. The weirdest thing, is when I am connected but can't get to the internet, I do a netstat or ifconfig wlan0, I do have an IP address and everything. It says I'm connected but its not. I have a Realtek RTL8188CU USB adapter.

• Java on Ubuntu server 12.04?

  - by Sean Dunwoody

  I'm a little confused at the moment. My back story in short, is that I'm trying to set up a Minecraft server on an Ubuntu server I've recently set up, obviously to do this I needed Java, but after googling for a short while I wasn't entirely sure whether it is possible (or legal?) to do so in Ubuntu 12.04 due to licensing type issues - so I installed open JDK instead which appears not to work properly with the Minecraft server software (I half expected this) I'm now considering uninstalling open JDK and instead trying to get proper Java on there instead, my question is, is this possible? Is it Legal? And if so how do I go about doing it? Because I'm finding it very difficult to find any instructions on how to do so for 12.04 . . .

• Help with Grub2 needed post 13.10 updgrade. Grub sees my opensuse12.3 but when selected hangs with black screen.

  - by sean farley

  This happened on last upgrade and I reinstalled opensuse. I want to avoid that this time. When opensuse controlled grub the options to boot either OS worked fine. The ubuntu one will not work. Are there grub settings I can change to get this working? Would it be better to get the opensuse grub to load, if so how can I do this. i can see the opensuse root and home directories from ubuntu (they are on a separate HDD) Thanks

• Where do I publish a program?

  - by Sean

  I have finished designing a little application for Pandora and I am not sure how I can get it out and share it with everyone. What should I do to help advertise it to the public and let other people use it? As of right now it is free, and I hope to keep it that way, so I don't want to spend any money to give it out. I had actually designed this application just for personal use, but hey, why should I be the only one to use it?

• How can I extract a list of Minecraft items and recipes?

  - by Sean

  I'm designing a robust system for resolving item dependencies in Minecraft and to do so, I need to maintain a database of items and recipes. Right now, this database has to be hand-crafted (no pun intended); I would like to know if it is possible to somehow query the Minecraft jars (or perhaps more realistically, grep through them) to extract this data automatically. How can this be done? The project is currently in Python, but it can still be ported to Java without much fuss at this stage. (For the curious.)

• Cannot connect to Xen domU via VNC if X isn't installed on domU

  - by Hai Minh Nguyen

  I'm trying to build a Xen domU that can be connected through the Xen's VNC server. Below is the template (actually it's generated by OpenNebula): name = 'one-153' #O CPU_CREDITS = 256 memory = '128' bootloader = "/usr/bin/pygrub" disk = ['tap:aio:/home/oneadmin/cloud/one/var/153/images/disk.0,xvda,w',] vif = ['mac=02:00:c0:a8:00:03,bridge=virbr0',] vfb = ['type=vnc,vnclisten=slave1,vncdisplay=1,vncpasswd=v98KXdFN'] The problem is that I can't connect to the domU if it doesn't have X. In this case all I got is a blank screen. Besides, if the domU has X, the screen is still blank until the login prompt appears, while it should be like this. Some information that may be useful: The domU and the dom0 both run CentOS 5.5. If the domU has X, it can be connected even when both X and the domU's VNC server isn't running. The VNC client is RealVNC.

• sudo: must be setuid root

  - by Phuong Nguyen

  Recently, due to some messy stuff with master boot record, I have to re-install my Ubuntu. Before doing that, I back up all folder (exclude root, bin, sbin, tmp, media, mnt) to a NTFS partition. After installation of Ubuntu, I copied back all the folder using a nautilus (running by sudo nautilus). After that, I reboot my computer. And boom, now I cannot run sudo any more, my network services cannot run. When I run sudo from a terminal, I ge "must be setuid root" error. In ubuntu, root account is disabled by default, I don't know why all these files is no longer under ownership of my account. How would I recover back?

• FreeNX is very unresponsive compare to VNC when using over LAN

  - by Phuong Nguyen

  I find FreeNX is quite unresponsive compare to VNC when using over LAN. I run Netbeans inside a Quad Core Server and remote desktop to it through both NX & VNC. For VNC, the screen will be nicely updated as I scroll the Netbean IDE For FreeNX, flickering happened and the mouse cursor become unresponsive as I tried to do the samething. Have anyone encountered the same? I don't like VNC because when VNC doesnot correctly understand the "Windows" key (interpreted as Super L instead of Mod) Is there any adjustment that can avoid that annoyance? I have tried both FreeNX-Server and NeatX-Server and both resulted in the same unresponsiveness.

• New install indicator while install updating on Ubuntu

  - by Phuong Nguyen

  In the update manager of ubuntu I see several libraries marked with New Install. I don't know what is the benefit I can get from that New Install? What if I just want a normal upgrade, not a New Install? (I have 3 Linux Kernel versions right now (that I can see and select from Grub menu), and I think I don't need all of them since I always use the latest Kernel).

• Separate mail section for POP mail account in Evolution

  In Evolution, if I use IMAP as the incoming protocol for the mail account, then this account will have a separated section. However, if I use POP as the incoming protocol, then this account is merged into On this Computer group. I want POP account to have a separated section. How would I do that?

• Seeking web-based FTP client for very large file upload

  - by Paul M. Nguyen

  I have looked around for these for some time... the limits imposed by the web server and/or the dynamic programming environment (e.g. PHP) are far too restrictive for the application I'm working on. We need to be able to move large graphics and video files to and from clients (ranging from tens of MB to a few GB in a single file). Plain FTP with a proper desktop client will do the trick, and we're hosting this in Amazon EC2 with EBS. User management will be done from the office via webmin. Users are chroot-jailed into their home dir by proftpd. net2ftp will work for many clients, but we often need to move single files that approach 1GB or exceed 2-3GB which is way out of the range of any http-based uploader. So we turn to Java or Flash - can they do it? From within the web browser establish an FTP connection and grab a huge file? There are licensed applets and such out there, but none seem convincing. Again, I'm looking for some code that can speak FTP and read (& write?) the local disk, that is delivered in a web browser, and can move single files of 2GB+. The reason for having a web-based interface to FTP is to skip the software installation step for our clients. I will consider proper desktop client software as long as it's "portable" and at least Win+Mac and can be easily configured by lay-man users in a hurry.

• Ubuntu: Tar doesn't work correctly

  - by Phuong Nguyen

  It looks like tar is having some problems. I installed Ubuntu 10.04 alpha a few of weeks ago. After that, this alpha version is so terrible that I must switched back to 9.10. So, I backed up all of my profiles data (/home/my_user_name) to my_user_name.tar.gz Here what I did: (in U10.04) Open Nautilus and goto /home/my_user_name Press Ctrl+H to view all hidden files. Press Ctrl+A to select all files Right click and choose [Compress...] Now, when I have set up Ubuntu 9.10 again, I extract the tar using Extract Here command from Nautilus. Funny things happened: Instead of extracting to current folder, the archive manager create a folder named my_user_name and put the extracted content into it. All of the files that I placed directly under /home/my_user_name doesn't get extracted All of the directories that started with . (dot) is not extracted. I wonder if there is any incompatibility between tar in U10.04alpha and U9.10 that cause the problem? Now every of my email, basket data is long gone. I'm freaking right now. Is there anything I can do to get the tar return back my data?
