• recent unreliable wireless connection

  - by gabkdlly

  Recently, my internet connection over wireless ( via a Netgear KWGR614 router ) has become unreliable, on both a Dell laptop running Ubuntu 10.04 as well as my Desktop running Ubuntu 10.10 . The problem does not seem to occur on a laptop running Windows Vista, nor on a Desktop running Windows 7 ( this machine is connected with an ethernet cable ). The problem does not seem to occur on my Openmoko Freerunner ( running Android 1.5 ), though I hardly ever use this device to connect over WLAN, so the problem may have just slipped by. On my main Ubuntu Desktop, I have tried the following wireless devices: a Longshine PCI card ( an old device with an RTL8180L chip ) a D-Link DWL-510 PCI card ( this device threw warnings in dmesg ) a USB device from MSI ( US54EX ). Usually my wireless network shows up in the network manager with a normal signal strength, even when the connection speed is slow or the connection gets reset ( asking me to click connect to re-authenticate my wireless connection ). I have observed this problem with a Netgear KWGR614 Router ( with the manufacturers firmware ), as well as with a TP-LINK TL-WR741ND router running OpenWrt. Taking a look at my routers logs, I find many instances of the following line: Tuesday,04 Jan 2011 03:53:01 [TCP SYN Flood][Deny access policy matched, dropping packet] I know that the Netgear router is susceptible to denial of service attacks, as I have previously been able to disrupt its operation by putting an nmap scan into a while loop. I use WEP or WPA to encrypt the wireless network. Is it possible that someone is jamming my signal ?

• Sound card not detected in 13.04

  I have a problem with my sound card. I don't have volume up or down option anywhere. In the setting -> Sound I don't have any card detected.

• How can I stop a process from moving to the background?

  - by Alex

  I have a machine running Ubuntu server version 12.04.3 LTS. On it, I'm attempting to run a node.js server that needs to stay up and running at all times. I'm running into an issue, however, where periodically I see this happen: [1]+ Stopped sudo node server.js When this happens, I have to manually bring it back with fg, which works fine, at least until it stops again. As far as I can tell, it isn't functioning properly while stopped, since I get no log files in those windows of time. So my question is this: Is there a way to prevent it from being stopped like that? I'm running it in a tmux window, if that changes anything. Also, to address the question before it gets asked: I'm running it as sudo due to some ecryptfs issues I've been having. I was originally running it in my home directory, but when it was left alive for too long things would get out of sync and the file writes it has to do would just stop working. To mitigate that, I moved it out of my home directory, but its new location requires me to use sudo permissions for everything to work correctly. Hopefully that isn't related to the whole background task thing. (sudo and tmux tags included in case one or both turn out to actually be relevant to the solution.)

• WiFi slow sometimes, reboot helps, how do I debug it?

  - by January

  Ubuntu 12.04.1 with all updates installed. Laptop Lenovo Thinkpad X230 with Intel Corporation Centrino Advanced-N 6205. WiFi sometimes becomes extremely slow. Often this occurs when I wake the system from suspend and connect to a different network. I find no obvious clues in system logs. /etc/init.d/network-manager restart doesn't help, but a reboot does. How can I go on with debugging this issue? In specific, which parts of the system should I try to restart (without a complete reboot)? I know of problems with Intel WiFi (see for example this question and the instructions here), but if that was the problem, I would expect the WiFi to be slow at all times, and not just sometimes. Also, I have a gut feeling that it might be a DNS issue (for example, getting a page from a known server is faster than accessing a new server), but I don't know how to tackle it. Update: despite numerous updates in the meanwhile, I still observe this behavior. It happens always when I access my WiFi router at home after returning from work; when I reboot my laptop, the connection speed is good again.

• Recover Lost data/partition

  - by Kaleido

  This is what happened: I was running 12.04.1 and wanted to install 12.10. upgrade, but a fresh install. When setting up my computer I anticipated for this by dividing my 640GB HD in following partitions: 1. 60 GB for Ubuntu, boot 2. 576 GB for data, mountpoint /home 3. swap, 4GB The idea was to manually select the correct partition in the installer but I got distracted for a moment and selected the wrong option. Result: The installer started repartitioning the entire HD. When I noticed this I interrupted the installer, but upon reboot it was clear that I was too late, no OS to boot to. I booted from a Gparted Live CD to see if I could recover the data on my previous /home-partition, but it's gone. Is there any way to recover the lost data? I searched around and read alot about Testdisk, but in all the tutorials I've seen, the set-up has been much easier than what I'm facing. I've not only lost my partition table, it's been replaced. Thanks in advance for any ideas that might help! If extra info is needed, please specify and I will do my best to provide.

• Wifi interface changes name seemingly at random

  - by ray_voelker

  I'm currently having some issues getting a wireless interface to work continuously under an install of Ubuntu 12.04.1 LTS. Some of the issues I'm experiencing include Connection will drop out after some time after it has initially worked. Interface will be a different name after a reboot. For example, wlan0 will become wlan4 when using the ifconfig -a command. Ubuntu will take a long time to boot, looking for network adapters. The purpose of this build is to function as a web kiosk in a library. The computer is supposed to boot up into a web browser, and allow for browsing of the catalog. For some reason this interface does not appear to be working as it should. Are there any explanations for some of these problems I'm having, and perhaps some solutions? The wireless card appears as this after doing an lspci ... Ralink corp. RT2561/RT61 802.11g PCI In the /etc/network/interfaces file I have the following configuration for the interface. auto wlan0 iface wlan0 inet dhcp wireless-essid UDwireless wireless-mode Managed Thanks in advance for help on this.

• How do I configure an Intel HD Graphics 4000?

  - by derabbink

  First off, please note that last night I already posted this question to a launchpad mailing list, so this could be considered a cross post. However, I think this is a better place to ask the same question The question: How can I configure my Ubuntu 12.04, with upgraded kernel (3.6), to use the Intel HD Graphics 4000 adapter? (Intel HD 4000 is the standard of 3rd gen Intel Core i7 (Ivy Bridge) graphics adapter) Some output: $ glxinfo name of display: :0 X Error of failed request: BadRequest (invalid request code or no such operation) Major opcode of failed request: 154 (GLX) Minor opcode of failed request: 19 (X_GLXQueryServerString) Serial number of failed request: 12 Current serial number in output stream: 12 $ cat /etc/X11/xorg.conf this is probably the farthest from what it should be Section "Screen" Identifier "Default Screen" DefaultDepth 24 EndSection Section "Module" Load "glx" EndSection $ lspci I only listed the line I think are relevant.

• How do I add a boot from cd option to yaboot?

  - by Sergiu

  So I'm dual-booting Ubuntu 12.04.1 on my iMac G5 powepc alongside Mac OS X and I want to add a boot cd option to yaboot because I'm trying to boot a scratched Mac OS X installation DVD that takes a while to read and the frst bootstrap moves on too fast. How do I edit the timeout for the first bootstrap anyways? So, my main question is, how do I add a cd booting option to yaboot and then, how doI boot it? The devalias from OpenFrmware tells me that 1 have 2 cd-rom instaled, on is /ht/pci@3/ata-6/disk@0 and the other on ends with a 1 instead of a zero. These are the contents of my yaboot.conf file: yaboot.conf generated by the Ubuntu installer run: "man yaboot.conf" for details. Do not make changes until you have!! see also: /usr/share/doc/yaboot/examples for example configurations. For a dual-boot menu, add one or more of: bsd=/dev/hdaX, macos=/dev/hdaY, macosx=/dev/hdaZ boot="/dev/disk/by-id/scsi-SATA_ST3160023AS_5MT1GCWA-part2" device=/ht@0,f2000000/pci@3/k2-sata-root@c/@0/@0 partition=4 root="UUID=798a048f-ee48-49e0-bba3-111aed8dee04" timeout=12000 install=/usr/lib/yaboot/yaboot magicboot=/usr/lib/yaboot/ofboot enablecdboot macosx="/dev/disk/by-id/scsi-SATA_ST3160023AS_5MT1GCWA-part3" image=/boot/vmlinux label=Linux read-only initrd=/boot/initrd.img append="quiet splash" What do I add here so that yaboot will boot from my cd in like 3 minutes after startup? Thanks!

• Why am I getting [mount error(22): Invalid argument] while trying to mount SMB network drive?

  - by Steve_

  Disclaimer: I am very new to Linux :) Anyway, onward: I have a fresh instance of Ubuntu Server (12.04.1 LTS) running on my network and I want to mount a network drive to the server so I can access the contents. The network drive is a SAMBA compatible drive running Darwin OS. If I run the following command: smbclient -L //192.168.0.2 -U myuser It prompts me for the password and then displays output similar to: Domain=[SERVER01] OS=[Darwin] Server=[@(#)PROGRAM:smbd PROJECT:smbx-105.4.0] Sharename Type Comment --------- ---- ------- Comp Staff's Public Folder Disk CompRaid03 Disk Dropbox Disk Groups Disk IPC$ IPC Public Disk Users Disk compstaff Disk However, when I try and mount the CompRaid03 share, using this command: sudo mount -t cifs //192.168.0.2/CompRaid03 /mnt/myshare -o username=myuser I get the same password prompt, but after putting the correct password in, I received this error: mount error(22): Invalid argument dmesg | tail returns: [23576.037373] CIFS VFS: cifs_mount failed w/return code = -22 I don't understand what is wrong with this command. I've managed to mount a share on my current (Windows 8) machine using basically the same command but with a different IP address and share name (obviously). I've spent a good few hours trying to solve this and got no where. Any help or pointers would be greatly appreciated. Thanks Steve EDIT As suggested I've also trued using "user=" instead of "username=": sudo mount -t cifs //192.168.0.2/CompRaid03 /mnt/svnrepo -o user=myuser This results in the same "Invalid argument" error.

• How do I make a Live USB without destroying my Windows computer?

  - by user71089

  Unlike every other post I have read, let me begin by saying that I am TERRIFIED of destroying my Windows 7 home system in the attempt of making a bootable Ubuntu Thumb Drive. I very specifically DO NOT want to attempt configuring a dual boot system. What I am seeking is a portable operating system on a thumb drive, through which I can run my COREL software via VirtualBox-4.1.16-78094-Win. I want to be able to use my own software on my work computer without any worries about screwing up the host system anywhere I go. Supposedly, I just made a bootable Thumb drive, having successfully loaded the ISO for ubuntu-12.04-desktop-i386 using Pendrivelinux's Universal-USB-Installer-1.9.0.1 However, all that I get is a Thumb Drive that wants to install Unbutu onto my PC's HDD. I am not finding any clear path to this end in the posts I am reading. Like it or not, Windows is a fact of life for me. The goal is to be able to use my software on my work PC without doing anything intrusive that will cost me my job. If I have a meltdown on my PC at home trying to make this happen, it will be nearly as bad. Is this even Do-Able? Can the process be made clear? Thank You, Ubuntu World ...!

• Why does my system slow down or freeze when there is heavy disk activity?

  - by user72270

  Im a first-time user to Ubuntu-12.04 with WUBI installation. My NoteBook Information : Dell vostro 3450 : i5 2410m, 3 gb ram, intel hd3000, amd 6630m hybrid. Surfing and playing games works flawlessly, however, I'm having huge problems when installing applications and generally copying and moving files. When doing so, system is significantly slower and freezes quite often (Firefox gets bluish, sometimes even black n white). I would say that Ubuntu allocates too much resources on file transfers and installing, but even these tasks are very slow. Here is very specific example : today, i tried to move 6 GB file from win 7 installation. It was good at first, i jumped to firefox but after a while firefox started to randomly turn bluish and mouse was randomly stopping working. It was gradually worse and worse and it got to a point when firefox black n whited and mouse wasn't working at all. I raged and went for some meal, when i got back screen was black. It probably unlogged me due to inactivity, when i pushed random button to bring screen to life i had to wait few minutes to let it show me only my screen background. No log in screen, just background and working mouse. NoteBook fan was working at 100 % so I assumed that file transfer was going on and I left it to work. Nothing then changed for a full hour so I hard rebooted it. File transfer unsuccessful, It transfered hardly 2 gigs. Is this normal ? What to do in these situations ? It didn't let me load system manager and not even terminal. Thanks.

• Grub not loading after Windows 8 Install

  - by RazorXsr

  My system was configured to dual boot Ubuntu 12.04.1 LTS and Windows 7. Today I got my hands on the MSDN release of Windows 8 and I installed it over my Windows 7. Now the computer just boots to Windows 8 directly without loading the GRUB screen. So I followed the steps as suggested in: https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows. Running this command: ls -l /dev/disk/by-label/ gives the following output: total 0 lrwxrwxrwx 1 root root 10 Sep 11 07:51 Entertainment -> ../../sda2 lrwxrwxrwx 1 root root 10 Sep 11 02:45 PENDRIVE -> ../../sdb1 Also fdisk -l command gives this as the output: Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x1246aa23 Device Boot Start End Blocks Id System /dev/sda1 * 2048 319582199 159790076 7 HPFS/NTFS/exFAT /dev/sda2 319582208 602906623 141662208 7 HPFS/NTFS/exFAT /dev/sda3 602908672 625135615 11113472 83 Linux Disk /dev/sdb: 1939 MB, 1939865600 bytes 64 heads, 63 sectors/track, 939 cylinders, total 3788800 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xc3072e18 Device Boot Start End Blocks Id System /dev/sdb1 * 2248 3788799 1893276 c W95 FAT32 (LBA) So I assume that I have to run this: sudo grub-install /dev/sda3 to get GRUB up and running. But I am getting this error: /usr/sbin/grub-probe: error: cannot find a device for /boot/grub (is /dev mounted?). Can anyone please guide me in the right direction? The current Ubuntu installation is far too customized to my needs to lose it to a boot manager issue! Any help is much appreciated!

• Black Screen (but with cursor) after wake-up from suspend to RAM

  - by Naseschwarz

  [Lenovo Thinkpad X60] After upgrading to 12.04, first thing I did was get suspend to HDD back, because I don't use my battery a lot. So I did that. After a while (about a week, I upgraded on release, not beta), maybe a week or so, I started getting black screens from time to time after waking it up from suspend to RAM. I never got that problem with suspend to HDD. As it only happens sometimes, I can't reproduce it o.O Sometimes it doesn't happen for a week (daily use, approx 2-6 wake-ups a day), then every single time. The precise symptoms are as follows: normally I got a black screen with my cursor on it, which can be moved, no problems there. I can't interact with the system in any way except for turning it off on the 1/0 button... the weird thing is, the cursor seems to react to what I had opened when going into suspend to RAM, so for instance one day I had writer open and then my cursor was a "I" for most of the screen. I only get this in 12.04, never had any problems with this in 9.04-11.10. Any ideas? Big thx in advance!

• Gnome-shell partially freezes

  - by user568021

  My specs: Ubuntu 12.04.1 LTS, Gnome3, Dell Studio laptop This is not happening all the time, but only sometimes .. totally randomly. When I'm in the middle of some work something totally weird happens. Keyboard suddenly stops working. I can't type, no matter which key I press nothing happens. I can't press Alt+Tab, I can't press Alt+F4, Alt+F2... nothing. Activities button is dead. Also right click does not work...and something even more annoying. I can click on the 'menu' in the top right corner(the menu pops up), but clicking on 'power-off' or 'suspend' option doesn't do anything. The only little thing I can do is: Close the lid of my laptop so it goes to sleep. Than wake it up again. And than it's ok. Everything works. So I guess restarting (or refreshing) gnome-shell fixes the problem. Sorry if the title of this question is odd... I don't know how to properly describe this.

• "drm:[drm_crtc_helper_set_config] *ERROR* failed to set mode on [CRTC6]" during install

  - by Warez J. Coxtrong

  I have a desktop PC which I built a while back. It has an Athlon XP 2500+, 2.5GB RAM, and an Nvidia (PNY Verto) Geforce 6200. I removed the CD drive to add another hard drive so I install from a USB flash drive. When I try to install 12.04 it seems to work just fine. The GUI boots up and wifi even connects to my router. I go through the language screen, the partition screen, the keyboard screen, the location screen, and the import my Windows settings screen just fine. But as soon as I'm done with all that the next screen goes black and displays this message: drm:[drm_crtc_helper_set_config] *ERROR* failed to set mode on [CRTC6] Since the GUI starts just fine earlier during the install, I know I shouldn't be having any display problems, but I am. How do I get Ubuntu to install properly? I have four IDE hard drives, all Western Digital: a 250GB, a 160GB, a 40GB occupied by Windows XP, and a 120GB that I'm trying to use for Ubuntu. 3GB of the 120GB drive are formatted for swap. I have checked the MD5sum of install image file and it all matches up. d791352694374f1c478779f7f4447a3f ubuntu-12.04-desktop-i386.iso

• Is this a b43 driver problem?

  - by Nullet

  I have 13.04 on a Dell Inspiron 1564 with Broadcom 4312 WiFi card. The wl drivers cause kernel panic on linux-3.8 so I succesfully installed the b43 driver a couple of months ago. Now I have changed ISP and got a new router, and the connection drop when downloading software from internet to a 2008r2 using Remmina Client, and apt-get install on virtual machines in virtualbox. I have no idea why this suddenly became a problem.. My phone does not loose the connection, just Ubuntu. Output from /var/log/syslog after lost connection rfkill list(after disconnecting): 0: phy0: Wireless LAN Soft blocked: yes Hard blocked: yes I can use NetworkManager to disable wireless and then enable wireless to connect again. rfkill ublock all/wifi/0 removes only Soft blocked. lshw -C network *-network description: Wireless interface physical id: 4 logical name: wlan0 serial: 78:e4:00:78:d2:05 capabilities: ethernet physical wireless configuration: broadcast=yes driver=b43 driverversion=3.8.0-32-generic firmware=478.104 ip=10.0.0.3 link=yes multicast=yes wireless=IEEE lspci 04:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01) After waking from suspend and when booting, it takes about 40 sec to get network connection. This has been a problem all along AND a different question, but I mention it anyway.. cus it's annoying! Please take a look and hopefully someone spot a problem! Thanks!
