• Missing Wireless access point

  - by nvcnvn

  I have an: Ubuntu 12.04 with proprietary Boardcom STA Wireless driver installed BCM43224 802.11a/b/g/n wireless card TP-LINK TD-W8101G 54Mbps Wireless ADSL2+ Modem Router Yesterday before I went to sleep, I still connect to my wireless access point, this morning when I start my laptop I don't see it in the list - there are some neighbors listed but not mine. The WLAN is green, with my old Nokia E72, I still see my access point with 100% signal. I have tried to restart my laptop and turn the firmware off/on by the switch but no help. I have read the WirelessTroubleShootingGuide but I can do anything. Here is some of my card info: *-network description: Wireless interface product: BCM43224 802.11a/b/g/n vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:04:00.0 logical name: eth1 version: 01 serial: c0:cb:38:06:5d:53 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=wl0 driverversion=5.100.82.38 latency=0 multicast=yes wireless=IEEE 802.11abgn resources: irq:17 memory:f0500000-f0503fff *-network description: Ethernet interface product: RTL8111/8168B PCI Express Gigabit Ethernet controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:09:00.0 logical name: eth0 version: 03 serial: f0:4d:a2:42:ab:e4 size: 100Mbit/s capacity: 1Gbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list rom ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=full firmware=rtl_nic/rtl8168d-1.fw ip=192.168.1.3 latency=0 link=yes multicast=yes port=MII speed=100Mbit/s resources: irq:42 ioport:5000(size=256) memory:f0404000-f0404fff memory:f0400000-f0403fff memory:f0420000-f043ffff

• Wifi installation issues on Ubuntu 10.10

  - by SlyrNemesis

  Linux newbie here, anyway so here is the problem, I run Ubuntu 10.10 and I have a Sitecom 300N x2 Wireless Network dongle with chipset 8192SU, I used ndiswrapper to install my Windows Wireless driver because Sitecom doesn't have a linux driver, it says hardware present but it doesn't find any Wireless networks, nor does it connect to one. What can I do?

• Gnome-Network-Manager Config File Migration

  - by Jorge

  I think I have an issue with gnome-network-manager, I used to have a lot of connections configured, Wireless, Wired and VPN. After upgrading to 12.04 (from 11.10) I lost every configuration. I realized that the configs that used to be saved in $HOME/.gconf/system/networking/connections now are being saved in /etc/NetworkManager/system-connections/. I don't know how to migrate my settings to the new config file format Can anybody help me? jorge@thinky:~$ sudo lshw -C network *-network description: Ethernet interface product: 82566MM Gigabit Network Connection vendor: Intel Corporation physical id: 19 bus info: pci@0000:00:19.0 logical name: eth0 version: 03 serial: 00:1f:e2:14:5a:9b capacity: 1Gbit/s width: 32 bits clock: 33MHz capabilities: pm msi bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=e1000e driverversion=1.5.1-k firmware=0.3-0 latency=0 link=no multicast=yes port=twisted pair resources: irq:46 memory:fe000000-fe01ffff memory:fe025000-fe025fff ioport:1840(size=32) *-network description: Wireless interface product: PRO/Wireless 4965 AG or AGN [Kedron] Network Connection vendor: Intel Corporation physical id: 0 bus info: pci@0000:03:00.0 logical name: wlan0 version: 61 serial: 00:21:5c:32:c2:e5 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwl4965 driverversion=3.2.0-23-generic-pae firmware=228.61.2.24 ip=192.168.2.103 latency=0 link=yes multicast=yes wireless=IEEE 802.11abgn resources: irq:47 memory:df3fe000-df3fffff jorge@thinky:~$ lsb_release -a No LSB modules are available.

• Good and easy way to share files on local machine

  - by jb

  I would like to have a directory that has following properties: Many users can copy files into it These files can be deleted/changed by these users (user A can delete/modify file that was copied into this directory) it cant be done using normal file permissions (because permissions are retained on copy). Here is what I found on the net: brainstorm idea blueprint Some use cases: Sharing music on local machine Simple git repository sharing (just make a bare repository writeable to many people) --- i know that there are solutions like gitosis Allow many developers to modify test instance of php app without giving them root (i guess they would copy files) --- I'm leading a team of nonprofit junior developers and I need to keep that one simple! EDIT AFAIK setting SGID bit is not enugh, it only affects newly created files --- and basic workflow for these use cases ivnolves copying and other operations (which cleave file's gid unchanged)

• Bash does not remember programs with non 0 exit status in history

  - by Amigable Clark Kant

  I enter a command. It fails. I press arrow up, modify something and enter it again ... hold it right there. It used to work like that. Now it's more like: I enter a command. It fails. I press arrow up, get the last command which didn't fail, likely "ls" or something useless and I type the whole thing again back by hand. What happened? It wasn't always like this. But it's quite some time since this behavior changed, I'll give you that. Some years ago, at least. How do I put some sanity back into my bash prompt?

• Stitch scanned images using CLI

  - by Adam Matan

  I have scanned a newspaper article which was larger than the scanner glass. Each page was scanned twice: the top and the bottom parts, where the middle part appeared in both images. Is there a way to quickly match and stitch these scanned images, preferably using CLI? The panorama stitching tools I know require lengthy configuration, which is mostly irrelevant: lens size, focus, angle etc. Hugin has a solution for this issue, but it isn't practical for batch jobs.

• ubuntu 11.10 foreman error

  - by user1060759

  Like this post I am also trying to complete this heroku tutorial I have installed and used everything (node.js, npm, express) successfully until I got to Foreman. I installed Foreman by first installing Ruby: alex@ubuntu:~$ sudo apt-get install ruby1.9.1 then installing Foreman. I am a newbie to Unix so I "sudo" perhaps unnecessarily here, but I got confirmation in the terminal that it had installed but also some errors: alex@ubuntu:~/NodeHelloWorld$ sudo gem install foreman Invalid gemspec in [/var/lib/gems/1.8/specifications/foreman-0.26.1.gemspec]: invalid date format in specification: "2011-11-10 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/term-ansicolor-1.0.7.gemspec]: invalid date format in specification: "2011-10-13 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/foreman-0.26.1.gemspec]: invalid date format in specification: "2011-11-10 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/term-ansicolor-1.0.7.gemspec]: invalid date format in specification: "2011-10-13 00:00:00.000000000Z" Successfully installed term-ansicolor-1.0.7 Successfully installed foreman-0.26.1 Then when I try to start foreman I get similar: alex@ubuntu:~/NodeHelloWorld$ foreman start Invalid gemspec in [/var/lib/gems/1.8/specifications/foreman-0.26.1.gemspec]: invalid date format in specification: "2011-11-10 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/term-ansicolor-1.0.7.gemspec]: invalid date format in specification: "2011-10-13 00:00:00.000000000Z" /usr/lib/ruby/vendor_ruby/1.8/rubygems.rb:926:in `report_activate_error': Could not find RubyGem foreman (>= 0) (Gem::LoadError) from /usr/lib/ruby/vendor_ruby/1.8/rubygems.rb:244:in `activate_dep' from /usr/lib/ruby/vendor_ruby/1.8/rubygems.rb:236:in `activate' from /usr/lib/ruby/vendor_ruby/1.8/rubygems.rb:1307:in `gem' from /usr/local/bin/foreman:18 Can anyone help me?

• Can't customize the application switcher

  - by Byron Hawkins

  I'm trying to change the shortcut for switching applications from Alt+Tab to Ctrl+Tab, but changes in the System Settings > Keyboard > Shortcuts > Navigation are being ignored. Even if I disable the Switch applications shortcut entirely, it still maps to Alt+Tab. At one point I had some keys remapped with xmodmap, but since then I have deleted that configuration and rebooted. My keyboard layout settings are all defaults. The OS is Ubuntu 12.04, with all software updated this afternoon. It would also be nice to have the variation of application switching that includes one icon per window, instead of one icon per application, since I am frequently switching between windows of an application and would rather not wait for the switcher to realize I want a different window of the current application. My other Ubuntu 12.04 install has the application switcher that I like, but I'm not sure how to choose between them on this install (which was set up by my university department). Thanks if anyone can help me with this.

• how to start LXDE session automatically after tightvncserver starts to make me able see desktop when connecting to the host via vncclient?

  - by Oleksandr Dudchenko

  I have system which is equipped with Intel Celeron processor 1.1 GHz s370 with 384 Mb of RAM on Intel d815egew motherboard which supports wake-on-lan function. I want to use such a PC for Internet sharing to the local network. Also this PC is a DHCP+DNS server as well as router/gateway. Based on above I decided to install Lubuntu as it is lightweight system. I installed Lubuntu 10.04.4 LTS from alternate ISO. System has no auto login. System boots and has acceptable performance. Host PC has onboard 4 network adapters: eth0 – ethernet controller which is used for Local Network connections. Has static address 10.0.0.1 eth1 – ethernet controller which is not used and not configured so far, I plan to connect printer here later on. eth2 - ethernet controller which is used to connect to Internet, which we plan to share for the local network wlan0 – wireless controller, it is used in role of access poit for local Network and has address 10.0.0.2 We want to control our gateway remotely. So, we need to be able to power it on remotely. To allow this I’ve done the following things: $ cd /etc/init.d/ made a new file with command $ sudo vim wakeonlanconfig Wrote the following lines to the newly created file, saved and closed it #!/bin/bash ethtool -s eth0 wol g ethtool -s eth2 wol g exit Made the abovementioned file executable $ sudo chmod a+x wakeonlanconfig Then included it into autostart sequence during boot. $ sudo update-rc.d -f wakeonlanconfig defaults after system reboot we will be able to poweron system remotely. Than we need to have a possibility to connect remotely to the host via SSH and VNC. So, I installed following packets with the following commands: $ sudo apt-get update $ sudo apt-get install openssh-server tightvncserver Add ssh daemon into autostart sequence during boot. $ sudo update-rc.d -f ssh defaults Power off the host PC $ sudo halt Then I went to remote place, send magic paket and powered the Host up. System started... And I connected to the host via Putty from remote system under Windows. Than logged in and run the command to start vnc server. $ tightvncserver -geometry 800x600 -depth 16 :2 VNC server successfully started and I got message like follows. New 'X' desktop is gateway:2 Starting applications specified in /home/dolv/.vnc/xstartup Log file is /home/dolv/.vnc/gateway:2.log Using UltraVNC Viewer programm under windows I connected to the host's vnc server, enterd the password and.... sow only mouse cursor in form of cross on a grey background of 800x600 dots, no desktop. Here is my .vnc/xstartup file #!/bin/sh xrdb $HOME/.Xresources xsetroot -solid grey #x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" & #x-window-manager & # Fix to make GNOME work export XKL_XMODMAP_DISABLE=1 /etc/X11/Xsession The Question: What I have to change and where to make LXDE session start automatically after tightvncserver starts?

• What emulation mode for an epson printer is best?

  - by deamon

  I'm looking for a color duplex printer for Ubuntu. My favourites are Epson B-310N and Brother HL 4050CDN. The latter should be work with linux, but I'd prefer the first one, because printing costs are cheaper. The epson printer has "Epson ESC/P Raster", "PCL3", and "Epson ESC/P2" emulation. Can I use the printer with one of those emulations under linux? Were there any restrictions (like unusable duplex)?

• minecraft wont take keyboard input

  - by Drew S

  After upgrading to 13.10 FTB(minecraft) wont take keyboard input after login in. I can click the buttons but it will not let me type in a address on multiplayer, or copy/paste with mouse. Since upgrading I cannot run the other mod packs either, only the one I had installed from 13.04. I get this when running a new modpack: 2013-10-28 15:14:52 [INFO] [STDERR] Exception in thread "Minecraft main thread" java.lang.ExceptionInInitializerError 2013-10-28 15:14:52 [INFO] [STDERR] at net.minecraft.client.Minecraft.func_71384_a(Minecraft.java:355) 2013-10-28 15:14:52 [INFO] [STDERR] at net.minecraft.client.MinecraftAppletImpl.func_71384_a(SourceFile:56) 2013-10-28 15:14:52 [INFO] [STDERR] at net.minecraft.client.Minecraft.run(Minecraft.java:733) 2013-10-28 15:14:52 [INFO] [STDERR] at java.lang.Thread.run(Thread.java:724) 2013-10-28 15:14:52 [INFO] [STDERR] Caused by: java.lang.ArrayIndexOutOfBoundsException: 0 2013-10-28 15:14:52 [INFO] [STDERR] at org.lwjgl.opengl.XRandR$Screen.<init>(XRandR.java:234) 2013-10-28 15:14:52 [INFO] [STDERR] at org.lwjgl.opengl.XRandR$Screen.<init>(XRandR.java:196) 2013-10-28 15:14:52 [INFO] [STDERR] at org.lwjgl.opengl.XRandR.populate(XRandR.java:87) 2013-10-28 15:14:52 [INFO] [STDERR] at org.lwjgl.opengl.XRandR.access$100(XRandR.java:52) 2013-10-28 15:14:52 [INFO] [STDERR] at org.lwjgl.opengl.XRandR$1.run(XRandR.java:110) 2013-10-28 15:14:52 [INFO] [STDERR] at java.security.AccessController.doPrivileged(Native Method) 2013-10-28 15:14:52 [INFO] [STDERR] at org.lwjgl.opengl.XRandR.getConfiguration(XRandR.java:108) 2013-10-28 15:14:52 [INFO] [STDERR] at org.lwjgl.opengl.LinuxDisplay.init(LinuxDisplay.java:618) 2013-10-28 15:14:52 [INFO] [STDERR] at org.lwjgl.opengl.Display.<clinit>(Display.java:135) 2013-10-28 15:14:52 [INFO] [STDERR] ... 4 more

• Absolutely Nothing Apearing in "Additional Drivers"

  - by Joshua Arroyo

  OK so I just got Ubuntu the other month or so. I'm running the 11.04 version currently and trying to install drivers for a Nvidia graphics card (it's my brother's computer and he currently cannot find the number of the card right now). I read that, to install the proper drivers for gaming, I would need to go into "Additional Drivers" and choose them myself. I clicked to go into "Additional Drivers" and it searched "for available drivers", then opened the additional drivers list. Lo and Behold, there was nothing, simply the message "No proprietary drivers are in use on this system" and the Help and Close buttons. Sorry if there's some silly simple answer to all of this, I'm new to this sort of thing (used to Windows simplicity, lol) and I really don't know what to do. Help would be much appreciated. Also, I should mention that the graphics card was installed and ran fine before switching from Windows XP to Ubuntu.

• How can I fix the "TERM environment variable not set" warning in eclipse

  - by Robert

  I'm running ubuntu 12.04 LTS and working with eclipse (juno) on a c++ project. I keep getting "TERM environment variable not set" in the console while trying to run the program. I realize this means the variable needs to get set. My question is what should it be set to and how do I set it? I've read that it should be 'xterm' in a few places. So I added export TERM=xterm in my .profile and while eclipse stopped giving me the warning, instead it would output unreadable garbage everynow and then (not a side effect of the program). It did display the program output but intermixed were weird characters. This leads me to believe it's not 'xterm' I should be setting TERM to. Or I'm setting it in an incorrect way. Any help is appreciated. Sample output: **TERM environment variable not set.** Please make a selection ----------------------- 1. Create a budget 2. Edit a budget 3. Display a budget 4. Save a budget 5. Load a budget 6. Exit What is your selection: 1 **TERM environment variable not set.** Enter the name of your budget: etc The program continues to execute as expected but the message is highly annoying As someone has commented, I do use system("clear") which is likely the source of the warning? Either way, is this likely just an eclipse issue or something I can fix in ubuntu/linux

• unity, seeing all instances of same open application windows on all virtual desktop

  - by Nasser M. Abbasi

  I noticed this strange issue with unity. I am using 12.04. The desktop has 4 virtual desktops, which I can switch between using the 'workspace switcher' which is very nice. But I noticed the following: When I have 2 instances of the same app (say 2 different firefox windows, or 2 different terminal windows), in 2 different virtual desktops, then I click on the icon for that application located on the launcher panel (the left long strip with icons on it), then I see the application comes into focus. Then when I click again right away (on the same icon on the launcher), then now all instances of this application that are open come into ONE view (may be on was on desktop 1, and the other was on desktop 3 for example) and then I can now click on the one instance window that I want to select to use. This is all very nice actually. But this does NOT work for all applications! I just tried it, and it worked for firefox, and for gedit and for the gnome terminal. I have one firefox window open in virtual desktop 1, and another window open in virtual desktop 2. I clicked once on the firefox icon, then again, and both windows came into the main desktop and I was able to select which one to use. When I tried the same thing on dolphin file manager, which I also had 2 windows (instances) of it open in 2 different virtual desktops, this behavior did not happen. I clicked again, and nothing happened. Only one remained in focus. So I had to fo look for the second dolphin window the hard way. It looks like some apps are supported by this feature and some are not. How does one make it so that all applications are supported like this? This is a very handy feature. Is it a configuration item somewhere? thanks

• 12.04 How do I disable the long press Super key from showing the shortcuts window?

  - by pt123

  Note this is the long press and not the one for the short press as mentioned here How do I disable the Super key? The super key has been a modifier long before Unity came, and I have used it on Compiz Zoom feature. So holding super down and moving the mouse scroll would zoom in and out the screen. But now in 12.04 the shortcut list screen pops up and it is irritating. I have also tried changing the keys to control +super + mouse scroll and a similar thing happens. Is there anyway to disable or change the long press super key for this, I have searched Compiz Unity plugin, the Systems Preferences - Keyboard shortcuts settings and haven't been able to find this.

• Accessing host LVM partition from Windows XP through Virt.manager 0.8.5 / Qemu / KVM

  - by Nico de Smidt

  Hi, requested use case is having a Windows XP SP3 guest running in 64bit Ubuntu. (Linux pcs 2.6.35-22-server #35-Ubuntu SMP Sat Oct 16 22:02:33 UTC 2010 x86_64 GNU/Linux) I want this guest to access an LVM LV on the Ubuntu disk. I've setup the following LVM config: --- Logical volume --- LV Name /dev/storage/sdc1 VG Name storage LV UUID Zg5IMC-OlqB-prL5-fgg4-3A9A-OgKP-oZ0QkJ LV Write Access read/write LV Status available # open 0 LV Size 1.01 GiB Current LE 259 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 251:3 -- 1) I've setup a storage pool for /dev/storage 2) I've mkfs.vfat /dev/storage/sdc1 3) and made a virtual IDE disk in the virt-manager setup for the guest. Target device: IDE Disk 2 Source path: /dev/storage/sdc1 -- Now when running XP (guest) Windows sees a new disk in Disk Manager and want's to install a partition on it, since it believes the drive is empty. After formatting from within Windows I can put data on the new disk volume. -- Back in Ubuntu however I cannot access this this any more since it created a partition within an LVM Logical Volume. Running fdisk -l shows the following: root@pcs:/media# fdisk -l /dev/storage/sdc1 Disk /dev/storage/sdc1: 1086 MB, 1086324736 bytes 32 heads, 63 sectors/track, 1052 cylinders Units = cylinders of 2016 * 512 = 1032192 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x8d72e4f4 Device Boot Start End Blocks Id System /dev/storage/sdc1p1 1 1050 1058368+ c W95 FAT32 (LBA) -- which seems fine to me, but when trying to mount /dev/storage/sdc1p1 I get the following error: mount /dev/storage/sdc1p1 /media/xp mount: special device /dev/storage/sdc1p1 does not exist which makes sense since in lvdisplay sdc1p1 does not exist Main question: I want to mount the vfat partition in both Ubuntu and XP What am I missing here????? regards, and thanks for your consideration.

• XFCE session with GNOME in background

  - by 100rabh

  Hi askUbuntu I recently installed XFCE on my Ubuntu 10.04 and it runs finely but with an issue. Everytime I login into my XFCE session I see the background image of GNOME session and after few seconds it disappears which gives me the impression that XFCE session is running over an already running GNOME session. If that is really the case then it might also be eating into my system's RAM which could be a bug. All helps and suggestions are welcome.

• Installation Problems & Antivirus

  - by Sagar Walvekar

  We have just migrated our systems from Windows to Ubuntu. We have more than 50 systems previously running Windows XP & Windows 7. After the release of 12.04 we decided to switch to Ubuntu. While we were installing Ubuntu 12.04 on Pentium 4 systems we have faced some issues. We tried it with a USB flash driver & CD. The typical configuration of the system is as follows: Pentium 4 with HT & 512 MB RAM, 40/80 GB IDE / SATA HDD. In windows there were several partitions and data on all the drives in all the systems. We have addressed this by taking backup of the C: drive on other drives & while installing Ubuntu we have just deleted & the C drive & recreated Linux partitions as follows - /root , /Boot, /Home & Swap.(in 10 GB) The problem is that the Linux gets installed without any error. However when I restart the system after the installation the system hangs in while detecting the HDD in BIOS and the system fails to start until I remove the HDD. When I installed the previous Ubuntu version it worked fine, without any hassle. Also if we install Ubuntu 12.04 on same HDD on any other higher capacity system & reconnected to old system it works fine. How can I fix this problem? Also, is there is any Antivirus which will give me real time protection on ubuntu 11 & higher versions with both 32 & 64 Bits?

• How to stop programs on starting from returning to log in screen?

  - by Bruce McKean

  I'm not a computer nerd but have been able to fix Ubuntu/Linux problems in the pass two years with a Google search but this on has me stumped. I upgraded to 12.04 about thirty days ago and all was well except that every time I tried to load KeePassX it would go to the login screen. I installed KeePass2 and all seemed to work. Last week I tried to load Bibble5 (Raw photo editor) and it would try to load and then back to the login screen. After a few days I gave up and downloaded Corel After Shot Pro (Corel's now owns Bibble5) and it has the same problem. Could someone please head me into the steps I need to follow to find out what is the cause. I'm interested in learning more about the Linux system how to correct any future problems thanks in advance – Bruce -Computer- Processor : 8x Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz Memory : 8155MB (1092MB used) Operating System : Ubuntu 12.04 LTS OpenGL Renderer : GeForce GT 520/PCIe/SSE2

  I'm running the latest version of firefox 17.0.1 on ubuntu 12.10 on a Acer Aspire One 722 Netbook. It has an amd dual core C60 processor and 2GB RAM. As you can see, firefox is absolutely killing my system, it responds really slowly and opening tabs is a royal pain. I have on an average 4-5 open tabs at a given time. Is there something that I can do to make my browsing experience more zippy? Additionally I run the following addons Firebug HTTPS Everywhere Ad block plus
