• Lost power during upgrade, how do I recover?

  - by Ryan McClure

  I was attempting to update my 11.10 install to 12.04beta. During the install step, I accidentally lost power to my laptop (the power cable came unplugged) and it shut down. Whenever I go to boot now, I can select my install via Grub and it loads up to where the sign-in should happen, but I get a display that looks like what you see as soon as you shut down. It looks like it locks after checking for the battery. Is there anyway, with or without Live media, to restore my machine's install/update to 12.04 but still keep my settings/applications/files?

• Incorrect key mappings in remote NX session

  - by Roger Light

  I'm using the NoMachine provided NX client on Ubuntu 10.10 running on a laptop. I'm connecting to a FreeNX server that happens to be running on openSUSE. I'm having trouble with keys being incorrect in the remote session. The most noticable example is that when I press up cursor, the screen shot dialog appears instead. As far as I can gather easily, the cursor keys and delete are affected. It's worth noting that it doesn't display the same behaviour if I dual boot to Windows XP, or from a different machine using openSUSE. I'm not really sure where to begin looking. Any suggestions?

  Mise à jour du 25.05.2010 par Katleen SAP en dit peu sur ses projets concernant Sybase, mais semble très interessé par l'intégration de ses technologies mobiles La direction de SAP reste très évasive quant à ses plans concernant le futur de Sybase et de ses technologies, suite à l'annonce officielle du rachat du second par le premier.

• package update in ubuntu on vitual box

  - by Ayusman

  while following one of the tutorials I needed to install a curl package. Here are my system configuration: Virtualbox 4.1 on Windows 7 64 bit. I have installed ubuntu 12.04 on the virtual box. When I try the following: sudo apt-get install curl I see the following errors: [sudo] password for userMe: Reading package lists... Done Building dependency tree Reading state information... Done Package curl is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'curl' has no installation candidate userMe@userMe-ubuntu:~$ When I try the same on a direct installation of ubuntu on a laptop (not a virtual machine) there is no problem. I am assuming this may be because of network settings. Please note that my work PC is in a corporate network and uses auto proxy settings (using a .pac file) for internet access etc. Any help will be appreciated.

• choppy streaming audio

  - by user88503

  I could use some help troubleshooting choppy streaming audio. The problem is jerky playback regardless of audio or video with audio. Both Chromium and Firefox have the problem, however files played directly on the machine with Rhythmbox sound just fine. I'm running 12.04 LTS on a C2D T9300. Most of the audio problems others ask about seem to be hardware related, so the following information might be relevant. sudo lshw -c multimedia *-multimedia description: Audio device product: 82801H (ICH8 Family) HD Audio Controller vendor: Intel Corporation physical id: 1b bus info: pci@0000:00:1b.0 version: 03 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: driver=snd_hda_intel latency=0 resources: irq:48 memory:f8400000-f8403fff

• Monitor Display issue

  - by dsiddens

  When booting I will have to boot maybe 3 or 4 times to get a screen that is not displayed diagonally or is not using the full screen width. Hardware specification: HP s7727c with AMD64 and NVIDIA chipsets and Insignia 22" monitor/TV. The Ubuntu version is 9.10 Karmic. I'd like to stay current with Ubuntu on this machine, but have gone down to 9.10 to get this described functioning. I tried higher versions and could not get past the "black screen" I think this issue is connected to the NVIDIA chipset/driver problem. I am a GUI user and I don't follow the other solutions posted which make use of the command line. I suppose if the command line solution could be given without making any assumptions of the receiving person's knowledge base, then even I and others like me, could implement it. Thank you for your time and assistance. Doug

• How should my local git workflow work?

  - by Anonymous -

  At home, I have a server that is running some software (on a LAMP stack, but only accessible internally). I have another machine and a laptop that I both use for developing said software. What is the best workflow for me? Should I have a repository on my local server, create a live branch, staging branch and development branch, then checkout the development branch from my laptop/development PC to work on, commit that back when I'm done, then merge the development branch with the staging branch for testing, before further merging to the live branch? Would I simply checkout the production branch to my /www/var/ on my server? Or am I thinking/going about this all wrong? Thanks.

• Ubuntu fail to start on a dual boot with Windows 7 on Vaio

  - by user94628

  I followed the instructions for the Ubuntu windows installer on my Sony Vaio laptop (model SVT131A11M). Upon restart I was prompt to choose the OS for boot (Win7 or Ubuntu), but then I shut down the machine and from the next boot, every time I choose to boot into Ubuntu, the GNU GRUB terminal appears with a grub> prompt. Now I'm able to boot into Win7, but can't boot into Ubuntu properly. Why does it happen and how come I was able to start Ubuntu successfully the first time?

• Choppy, stuttery & sped-up sound after update

  - by Synesso

  My audio has always worked perfectly on this hardware and 12.04. Yesterday I received an update, including a kernel update. Today the sound is periodically stuffed. In youtube, mkv files via VLC and embedded audio in web pages (memrise.com) the sound can become stuttery, sped up or stopped mid play-back. Where can I go to find if this is a known problem, or report it if it is not? Also, can I find a log that will tell me what packages were updated on my machine yesterday?

• Ubuntu 12.04 using UEFI

  - by Daniel

  I want to upgrade my machine with a new Motherboard, RAM and Processor. I am planning on doing a clean install of Ubuntu 12.04. The Motherboard I want to use is an Asrock 970 Extreme4 which uses an AMI 32 MBit UEFI BIOS. My Question is, is there anything I have to watch out for during the installation process? Cause I have read that some people have trouble booting into ubuntu using a UEFI BIOS. Any advice? I don't want to spend all that money for the different parts only to find out that I can only use windows properly. Thanks in advance

• Trying to get back seamless mode on my VirtualBox

  - by Newben

  I am trying from some days to activate again the seamless mode on my VirtualBox(using Ubuntu 12.04 on an osx device), which was correctly set till now but which isn't working anymore. I have had already this problem but then I had to reinstall a new disk on my VB. I tried everything I know : installing it by clicking on the 'devices' item in the nav bar of VB's app, I created a new dir in /media and then tried to mount the /dev/sr0. When running sh ./VBoxLinuxAdditions.run, it installed correctly But when rebooting my machine, I always have the same problem. Does anybody knows how to activate again Seamless Mode ?

• I installed Ubuntu alongside Windows but I can't see it in Windows' boot menu

  - by André Hallé

  I have a second machine where Ubuntu 12.04 LTS and Debian Squeeze are installed on the same HD and when I boot, I have this grub menu where I can choose which partition I will used. It works perfectly! But in my Windows environment that's another story. Now after making almost everything that I know, to make it work along Windows 7, there is no entry in the boot menu of Windows (I know, Ubuntu use grub but anyway there is surely a way to fix it, access it?). Why there is no Ubuntu entry? Why the installation gave me no error while I have this strange situation of having a "ghost OS" called Ubuntu installed somewhere in my second HD in a partition made especially for it and not being able to access it, starting it, having it working? Am I wrong? If I am, what's the problem? If I'm not, what's the need of Wubi?

• How do I Export to excel on aspx page?

  - by meltdownmonk

  I am trying to take data that I request from an access database and put it into and excel file on the client computer. I usually use ajax to request a summary of the data I need. It is formatted into an html table. I need that table to be in an excel format for the user to download. What I have tried already is to use the vb.net code to open excel and silently save the data to a file, however I realized it's the sever side that opens excel, not the client side, in my locally testing of the code, excel would open on my machine and create the file. When running this on the network, I realized excel isn't on the server, I am not sure if I should just install it, or try and steam the file.

• Fake RAID (dmraid) not seeing new SATA drives

  - by rausch

  I have three drives in my machine, one SSD with 32GB and two 1TB drives, attached to an Intel 82801JI (ICH10) SATA AHCI Controller. The problem is, that I can access only one of the 1TB drives when the other one is not plugged in. When it is plugged in I see the drives as sda and sdb, but there seem to be no partitions. Looking at these drives with cfdisk, the partitions are there, though. Both of the 1TB drives are carrying a partition, being part of a software RAID1, created with mdadm. Before I threw the SSD into the mix, the other two have been working fine. Any hints?

• How do I make Ubuntu go past the splash screen?

  - by John Baber

  I recently upgraded my desktop mac to Precise and now can't get past the Ubuntu 12.04 splash page. The splash freezes with ubntu and the dots turning from white to orange forever. This is when I choose 3.2.0-generic from the grub menu. If I choose to load up older kernels, I still get the same thing. How can I make my computer finish booting again? I'm able to ssh into the machine and poke around, but the actual screen freezes at the splash. dmesg cat kern.log

• How to fix additional STA driver installation error on 12.04

  - by nibl

  I have a Broadcom BCM4313 wireless driver. It worked fine under 11.04 and the upgrade to 11.10 also went smoothly. The 12.04 upgrade has broken the wireless connection. I've seen several posts about this and all presume you can activate the STA drivers, but that's where it fails on this machine. The log is in /var/log/jockey.log: WARNING: modinfo for module wl failed: ERROR: modinfo: could not find module wl WARNING: /sys/module/wl/drivers does not exist, cannot rebind wl driver DEBUG: BroadcomWLHandler enabled(): kmod disabled, bcm43xx: blacklisted, b43: blacklisted, b43legacy: blacklisted (repeat of last error several times) Any ideas how to proceed?

• XRDP crashes when using xfce desktop

  - by user291721

  I've been struggling with this for a few days. Currently using Ubuntu 14.04. I started out trying to use VNC and could connect but only received a black and white checkered screen when connecting using tightvnc from my windows machine. Seems that applications seem to have issues interpreting the gnome graphics. I then tried XRDP and received the same issue but was able to find enough information to get by this issue. After creating a .xsession file and setting the desktop to spawn an xfce4-session I was able to connect and the desktop displays, at least for a few seconds. After a couple seconds rdp crashes and I'm unable to connect again until I restart the xrdp service. Any help would be appreciated. Thanks

• What is the package name for JVM?

  - by JohnMerlino

  If I want to know if skype is installed, I would type this: viggy@ubuntu:~$ apt-cache policy skype skype:i386: Installed: 4.0.0.8-1 Candidate: 4.0.0.8-1 Version table: *** 4.0.0.8-1 0 100 /var/lib/dpkg/status Or if Eclipse is installed: viggy@ubuntu:~$ apt-cache policy eclipse eclipse: Installed: (none) Candidate: 3.7.2-1 Version table: 3.7.2-1 0 But let's say I want to know if the Java Virtual Machine is installed. How would I know what to pass to apt-cache policy? For example, you might not know what to pass to apt-cache policy for some programs: viggy@ubuntu:~$ apt-cache policy java N: Unable to locate package java viggy@ubuntu:~$ apt-cache policy JVM N: Unable to locate package JVM

• Empathy authentication error to XMPP server

  - by Shauna

  I recently installed Ubuntu 12.04 on a new machine and have been working on setting it up, but I've run into an interesting problem. I have a custom XMPP server for work (I don't control it, but we're using an in-house install). I can connect to it just fine via Pidgin, but due to some UI issues I'm having with Pidgin (and what appears to be better overall integration between Empathy and Ubuntu/Unity), I'd like to use Empathy instead. However, Empathy won't connect to my XMPP server, and I keep getting an authentication error and repeatedly prompted for my password. This happens even when importing the working account information from Pidgin (so I know things like the password are correct). Is there a way I can get Empathy working with my XMPP server?

• Redirect packages directed to port 5000 to another port

  - by tdc

  I'm trying to use eboard to connect to the FICS servers (http://www.freechess.org), but it fails because port 5000 is blocked (company firewall). However, I can connect to the server through the telnet port (23): telnet freechess.org 23 (succeeds) telnet freechess.org 5000 (fails) Unfortunately the port number is hardcoded (see here: http://ubuntuforums.org/archive/index.php/t-1613075.html). I'd rather not have to hack the source code as the author of that thread ended up doing. Can I just forward the port on my local machine using iptables? I tried: sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 5000 -j REDIRECT --to-port 23 and sudo iptables -t nat -I OUTPUT --src 0/0 -p tcp --dport 5000 -j REDIRECT --to-ports 23 but these didn't work... Note that: $ sudo iptables -t nat -L Chain PREROUTING (policy ACCEPT) target prot opt source destination REDIRECT tcp -- anywhere anywhere tcp dpt:5000 redir ports 23 Chain INPUT (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination REDIRECT tcp -- anywhere anywhere tcp dpt:5000 redir ports 23 Chain POSTROUTING (policy ACCEPT) target prot opt source destination

• BURG broken by Windows

  - by Sallée

  I have successfully installed, using Super Boot Manager, BURG in a computer at my work. After I boot into Windows XP, BURG is no longer operational. The machine just boots to the BIOS screen, goes black, and then boots to the BIOS screen again ad infinitum. The only way to recover I have found so far is to use a Boot-Repair USB, which restores either GRUB2 or MBR, not BURG. Everything works fine under GRUB2, but I prefer the improved look of BURG to make things easier on my students.

• Minecraft: Slow performance OUT of the game

  - by blackn1ght

  I downloaded Minecraft yesterday to see what the fuss is about, brilliant game! When playing in Windowed mode, if I try and do anything else, i.e. use the computer, when the game is paused, the computer is incredibly slow, it takes a minute just to type a short message into empathy. Also, once I quit the game, the computer remains slow for about 5 minutes, until it magically frees up and becomes fast again. Could this be related to the 512mb RAM limitation of Java, and the machine is swapping? Even trying to submit this post is incredibly slow and frustrating, it's taking me a minute just to click in the 'Tag's box. Any ideas? Ubuntu 10.10 x64 Intel Q9550 4GB RAM nVidia 8800GTS 320mb (w/prop drivers installed)
