• A specific user is unable to log in to vsftpd

  - by HackToHell

  I am setting up a new user let his name be ftpguy. He has access to only one directory /var/www/xxx. I have already chowned the directory so that he has write and read privileges. The user is also unable to login via ssh as I have disabled that by changing his shell to /sbin/nologin. Also, in vsftpd config, I have enabled the chroot_local_user. Now whenever I log in from ftp, i get an auth error. Connect socket #1008 to xxxxxxxx, port 21... 220 Welcome to blah FTP service. USER ftpguy 331 Please specify the password. PASS **** 530 Login incorrect. I changed the password to something different several times, using the passwd command, nothing happens, i still the above error. However I am able to log in with my ssh creditals to my ftp server without any problems.(I do not use a key).

  - by balg

  I have installed banshee, but during the installation something went wrong and now i am experiencing this: balg@scorpion:~$ banshee Unhandled Exception: System.TypeLoadException: Could not load type 'Banshee.ServiceStack.DBusServiceManager' from assembly 'Banshee.Services, Version=2.4.0.0, Culture=neutral, PublicKeyToken=null'.

• Glade: How can I set the value of a spin button?

  - by espectalll123

  I've done some spin buttons with Glade for my Python/GTK3 app, but I don't know how to set things like default, lower or higher value. How can I do it?

I can't understand it :P

• How add cpu frequency that should be available?

  - by Andrew Redd

  I have a system with an Intel Core i7 970 that should be able to run at 3.2 GHz. I'm running ubuntu 12.04 and installed the cpufreq indicator to be able to change the governor and noticed that I only had frequencies up to 2.0 GHz available to me. I set to performance and checked with cpufreq-info cpufreq-info -c 0 cpufrequtils 007: cpufreq-info (C) Dominik Brodowski 2004-2009 Report errors and bugs to [email protected], please. analyzing CPU 0: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 0 1 2 3 4 5 6 7 8 9 10 11 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 10.0 us. hardware limits: 1.60 GHz - 2.00 GHz available frequency steps: 2.00 GHz, 1.86 GHz, 1.73 GHz, 1.60 GHz available cpufreq governors: conservative, ondemand, userspace, powersave, performance current policy: frequency should be within 1.60 GHz and 2.00 GHz.

• .wine-pipelight folder not present

  - by DaimyoKirby

  Following the instructions on the pipelight installation page, I installed pipelight on Ubuntu 14.04. However, upon opening firefox the .wine-pipelight folder isn't present in my home folder, and I get the following errors: [PIPELIGHT:LIN:unknown] attached to process. [PIPELIGHT:LIN:unknown] checking environment variable PIPELIGHT_SILVERLIGHT5_1_CONFIG. [PIPELIGHT:LIN:unknown] searching for config file pipelight-silverlight5.1.

I've reinstalled quite a few times and ran through many of the common fixes offered on the pipelight Launchpad pages and here on AskUbunta and still it fails to run. Is there a reason why this folder isn't present, or why I'm getting these errors? Edit: Oddly enough, the .wine-pipelight folder is created wtih I open Nitro, although this still doesn't fix the issue.

• How do I align my partition table properly?

  I am in the process of building my first RAID5 array.

• Send arbitrary commands to modem for info

  - by mydoghasworms

  I have a USB 3G data card and modem. According to the supplier, to check the data balance on the account, I must dial a number like *89# (or whatever) from the handset. The device appears as a ppp0 interface in my network devices. How does one go about issuing commands to the modem to send the commands and receive back the information? UPDATE: OK, I found some help here: http://www.linuxquestions.org/questions/linux-hardware-18/sending-at-commands-to-a-sms-modem-372445/, but firstly, there are 3 ttyUSB devices on my system, and I assume that one of them is the 3G modem, but how can I tell? Secondly, trying to echo something to two of them says that the device is busy, which stands to reason, because I am using it to connect to the internet. Some help, please?

• Why Clonezilla needs to reinstall grub?

  - by Pablo

  By default CloneZilla Live will reinstall grub after restore. In my particular case I am restoring a disk image to same phisical disk without any partitioning/size change. I am expecting to have exact same state as I had right after backup. However, reinstalling grub will render my system to unbootable. If I remove that option [-g] then everything is fine. My question is in what cases and why CloneZilla ever need to re-install grub when restoring disk image?

• Hash Sum Mismatch using preseed (Ubuntu Server 12.04)

  - by xorma

  My install through Preseed fails at around 80% on Select and Install Software. In VT-4, I can see Hash Sum mismatch errors. This may be because I am going through a firewall which is caching files. There is no-cache option for apt but I can't seem to get it to work with Preseed. Have tried: d-i debian-installer/no-cache string true d-i apt-setup/no-cache boolean true d-i preseed/early_command string mkdir -p /target/etc/apt/apt.conf.d; echo "Acquire::http {No-Cache=True;};" > /target/etc/apt/apt.conf.d/no-cache but none of these are working. It appears that the early_command occurs too early so is over written once install starts. I'm not sure if the other commands are even correct. Anyone know what is the correct way of disabling achieving this through Preseed?

• Prevent SyncTeX from opening new instance Evince?

  - by Kris

  I'm using the SyncTeX plugin in gedit and it seems that ctrl-clicking in gedit (forward-searching) opens up a new instance of Evince even if there was already an instance open. Is there a way to prevent this from happening? The SyncTeX forward search clearly calls evince in a way that is not the same as e.g. nautilus would. By the way, I compile my tex files with a script using the "external tools" plugin. The line that opens the pdf file uses xdg-open.

• Nautilus will not launch after update to 12.10

  - by dereksalerno

  I updated to Ubuntu 12.10 today from 12.04 using the graphical update tool. Everything seemed to be fine until I went to open Nautilus, and it would not open. Bizarrely, I am able to open a file that I happen to have on my desktop, but when I click on the launcher, it never opens. When I enter 'nautilus' in the terminal, I get this: (nautilus:8557): Gdk-CRITICAL **: gdk_x11_display_get_xdisplay: assertion `GDK_IS_DISPLAY (display)' failed zsh: segmentation fault (core dumped) nautilus I am not a total novice with ubuntu or linux, but all I can tell is that there is some problem with X. Can someone please point me in the right direction as far as fixing this? I really don't want to have to do a fresh install. Thank you very much.

• Bumblebee - Poor performance with games

  - by user106880

  I have an Alienware M14x (GeForce 650m with Optimus) and got Bumblebee working correctly (trying to get ready for steam for linux :)). Also I'm running Ubuntu 12.10 with Unity. I get great framerates with glxgears and sauerbraten (a game on the repositories), but when I run games like Bastion and Splice, I get pretty terrible framerate, in fact worse than my integrated intel gpu. I have nvidia-current installed under ubuntu-x-swat/x-updates so it's driver version 310.xx. Also I forgot to add that I haven't been able to test other drivers because they seem to break glx (x can't load the glx module). I've been troubleshooting this for days now, and I'm very nearly out of ideas. Any hints on why only some games are running so poorly with bumblebee?

• Ubuntu 12.04-2 does not install with UEFI

  I'm in trouble to instal Ubuntu in Insipiron 14z. I've already created this question (that was wrongly marked as duplicated): First question But, the error seems to be with UEFI. If I disable UEFI on BIOS Setup, I can get into installation process of Ubuntu normally. But, I didn't finish the installation process because I think that will screw Windows 8 installation. So my questions is: Ubuntu installation should work with UEFI. So, why it didn't? Knowing that the error is with UEFI. I can forget the errors listed here?

• Problem installing ubuntu touch on galaxy nexus

  - by Francesco

  I've installed ubuntu touch on my galaxy nexus following the tutorial on the official site. However the latter is not so clear.. In particular, during the installation, user action on the phone is requested and not documented on the tutorial: 1) The phone asked me whether rebooting, wiping the cache or something else (i did nothing and the phone rebooted) 2) The phone asked me whether replacing or not cmw (or something similar). I asked no.. After the installation all seemed to work correctly. However after shutting down the phone can't power on anymore... When I push the power button the battery icon appears, showing that the battery is completely charged. What am I supposed to do?

• alsHigh CPU load - Ubuntu 14.04

  - by watt

  I noticed that sometimes when browsing (with other processes in the background), I get very high CPU load for the browser process (over 100%) and the computer becomes really slow. I tried switching from Firefox (with just a few extensions) to Chromium, but same thing happens without me visiting graphics-intense sites, flash sites or anything like that. I also noticed python or node (when running "make") produce the same high CPU load from time to time so this is not necessarily browser-related. When I only have a browser open, it doesn't seem to happen and everything is fine in Windows 7. I switched from unity to gnome3 with no effect. Specs: lenovo w510 (4gb RAM, i7 q820 @ 1.73) + up to date Ubuntu 14.04 64bit. Printscreen: http://imgur.com/8MZJNKC Do you guys have any idea why this might happen? Please let me know if there's other info you need. Thanks!

• How can I build the best Cyber Cafe possible using Ubuntu (Desktop or the Server Edition)?

  - by Osman Hassan

  My question has to do with my plan/dream of opening a Cyber Cafe in Mogadishu, Somalia, my birth place. I plan to use 5 to 15 computers (all laptops) running Ubuntu. Now that you have the background to my question, I need your help, advice and expertise. What type of computer (laptop) should I use for this project? What type of operating system (Ubuntu Desktop/Ubuntu Server Edition) should I use? How can I setup a file and printer sharing server? What program should I use to manage the client computers? If you have done this before and can point me to the best and easiest way to build this Cyber Cafe, I would appreciate it tremendously. Also, if you can point me to any books, articles, or blogs which I should read, I would appreciate it too.

• Linux installation on Acer Aspire One D270

  - by ronnie

  I was planning to buy Acer Aspire One D270 within a few days and as everybody installs linux on their netbook I was also planning to do that. Now, my question is how is Acer's hardware compatibility with linux and specifically in respect to the new Acer Aspire One D270. Has anybody tried installing linux on these new netbooks. It will be a great help if a D270 user can share his/her experience with linux usage. I read on some forums that there is some linux driver issue with Intel GMA 3600 and that people are not able to adjust their brightness. So, as I am a linux noob is this a major issue or not. Specs: RAM : 2Gb DDR3 Processor: Intel N2600(Cedar Trail) Graphics: Intel GMA 3600 HardDisk: 320Gb 5400 rpm

• What are the legal consequences of customizing the LiveCD?

  - by Voulnet

  Hello everyone, the organization I work at wants to create a custom Ubuntu LiveCD, the customizations are: Pre-installed programs, plugins, some device drivers, and aesthetics such as icons and backgrounds, as well as changing Firefox's homepage and removing unneeded packages. Not big changes, obviously, and we wish to distribute this custom image for clients to use as a bootable CD or USB stick in order to have a quick environment where all our tools are available instantly. What are the licensing and legal consequences of this? What if some of the programs or plugins that are to be pre-packaged are not GPL'd? I should finally note that we are not changing any code in the kernel or any other distro component. Thank you for your time!
