• Acer touchpad multitouch not working

  - by Lassi

  I tried to get my Acer laptop's touchpad working properly. I installed driver package (psmouse-alps-dkms_0.10_all) which made the side scrolling working. However, the touchpad supports multitouch (works on Windows), but Synaptiks claims that only 1 finger is detected by the touchpad. Thus 2 finger scrolling, pinch & pan zoom and those are not working. Any ideas how I could get these multi-finger gestures working?

• Creating a bootable flash without overlayfs

  - by Septagram

  I want to create an USB stick to carry my Ubuntu everywhere around with me. It's not intended to spread Ubuntu by installing it everywhere, but rather for running my configured system on any computer I come across. So far, I went with installing Ubuntu with unetbootin, however, I have some issues with this. When installed with netbootin, the original disk image is kept intact on the flash drive, forever. Also, a file is created for persistent storage and during boot it is accessed together with the image by overlayfs. This, in my opinion, has the following problems: If system is updated regularly, then files from the image are overwritten in persistent storage, doubling their size and wasting precious space. Persistent storage has a fixed size that you have to define from the start, again, wasting precious space. I'm not 100% sure, but maybe using overlayfs makes disk access slower, and more so on the relatively slow devices. So I'd like to find another solution: either to get rid of the original image or to install Ubuntu "normally" on the separate ext2 partition, or maybe even install it in the main vfat partition on the USB stick. Suggestions?

• Error while installing Komparator4

  I downloaded Komparator source from this page. The INSTALL file in the source say the following: Unpack komparator4-xxx.tar.bz2, and open a shell inside this directory mkdir build cd build cmake -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix` .. make sudo make install I unpacked the file, make the directory, entered this, but when I have tried to cmake (sentece Nº3) the terminal print the following errors disabling me to make & install: CMake Error at /usr/share/cmake-2.8/Modules/FindKDE4.cmake:98 (MESSAGE): ERROR: cmake/modules/FindKDE4Internal.cmake not found in /home/lucio/.kde/share/apps;/usr/share/kde4/apps Call Stack (most recent call first): CMakeLists.txt:2 (find_package) CMake Warning (dev) in CMakeLists.txt: No cmake_minimum_required command is present.

• How to solve: "Connect to host some_hostname port 22: Connection timed out"

  - by Aufwind

  I have two Ubuntu machines. Both have openssh-client and openssh-server installed on them. ssh-ing from machine G (fresh Ubuntu 11.10 installation) to machine K works great. But ssh-ing from machine K to machine G results always in the Error: Connect to host some_hostname port 22: Connection timed out I went through the troubleshooting section of help.ubuntu.com and I got the following results: ps -A | grep sshd # results in 848 ? 00:00:00 sshd - sudo ss -lnp | grep sshd # results in 0 128 :::22 :::* users:(("sshd",848,4)) 0 128 *:22 *:* users:(("sshd",848,3)) - ssh -v localhost # works! - sudo ufw status verbose # yields: "Status: inactive" I haven't change anything in the config file. What can I do to locate the Problem and solve it? Glad about every hint! Edit: ping was succesful in both directions! I did a telnet <machineK> 22 from machin G which resulted in Trying and then in telnet: Unable to connect to remote host: Connection timed out. But telnet the other way around worked just fine! Edit 2: ssh start/running, process 966 # yields: ssh start/running, process 966 /etc/hostname # contains my hostname, let's call it blubb /etc/hosts # contains the following 127.0.0.1 localhost # 127.0.1.1 blubb 129.26.68.74 blubb # I added this! - sudo service ufw status # yields: ufw start/running I installed Gufw and set it to ON. Then I selected from Incoming the option ALLOW. Then I sshed to another machine from where I sshed back to my machine. Still the same error as above: connect to host blubb port 22: Connection timed out Any more hints, what I can check?

• What does /dev/null mean in the shell?

  - by rishiag

  I've started learning bash scripting by using this guide: http://www.tldp.org/LDP/abs/abs-guide.pdf However I got stuck at the first script: cd /var/log cat /dev/null > messages cat /dev/null > wtmp echo "Log files cleaned up." What do lines 2 and 3 do in Ubuntu (I understand cat)? Is it only for other Linux distributions? After running this script as root, the output I get is Log files cleaned up. But /var/log still contains all the files.

• Just installed 13.04 and everything is fine except I cannot connect to the internet. Any thoughts?

  - by razorccatu

  I just installed Ubuntu 13.04 on my HP G62 laptop and the install went smoothly. I did the install off of a USB drive after trying ubuntu. While I was testing it, I connected to my Wireless with out issue and surfed a little. After the install, no wireless. I can still connect to my wireless network (at least it tells me I'm connected at full strength) but No servers can be found. I attempted to ping Google to no avail and I attempted to ping my router to no avail. I tried to then hard wire the machine and once again it told me that I was connected but I was not. When I ran dmesg, I got the following message: Warning: nss-myhostname is not installed. Changing the local hostname might make it unresolvabe. Please install nss-hostname! Is the hostname the issue? if so, how do I resolve it with out internet connection? If it's not the issue, how do I move forward? Thanks for any help. EDIT. I forgot to attach the image of my ifconfig if that might help.

• Unity Dashboard won't find local files, rearrange icons on two computers

  - by Stanton.Sculpture

  Suddenly I can't move icons around my unity launcher and the Dash won't search for my local files and folders. Was working when I first installed 13.10, but now it won't search for local files, and it won't let me rearrange the icons in any way. I've tried turning on and off all the scopes (lenses?) in multiple combinations, but it won't find any files unless I use nautilus to find them its mostly unresponsive. I can't see my recently used files, or files and folders scope at all. Dragging and dropping the icons on the side dock doesn't work, they only stick to my mouse until I put them back where they were. I cannot unlock any icons from the launcher, it just doesn't do anything when I click it. I tried rebooting both of my computers and its still won't function normally. I used ubuntu-bug -w to report a bug, no one has gotten back to me. Is there some option that I changed to cause this? This is a problem on both my laptop and Desktop. Please Help, Alex

• problem with task switcher and ccsm

  - by user2427

  I'm trying to make a simpler task switcher work, instead of the default with unity. I installed ccsm, and then the extras to be able to access to static task switcher. The problem right now is that I can enable static task switcher but only if I run ccsm as sudo. When I try to enable running ccsm without sudo it doesn't let me enable anything. All the checkboxes are disabled. And enabling as sudo doesn't make the task switcher work. Does anyone know how to make this work?

• custom libindicator icon is not displayed

  - by Christoph Sterz

  Hi there, I want to change the statusicon of my own little reminder program. Currently I am using GTK.StatusIcon but I want to use a ApplicationIndicator. Therefore I created an own Icon and moved it to: /usr/share/icons/ubuntu-mono-dark/status/22 It is named indicator-notify.svg Heres the code for the icon. ind = appindicator.Indicator ("notify", "indicator-notify", appindicator.CATEGORY_APPLICATION_STATUS) ind.set_status (appindicator.STATUS_ACTIVE) This Icon is not displayed. Although every other icon from this folder is. What did I miss? Is there maybe the need to "register" the icon in GTK ?

• Bash command history not working

  - by creepylol

  The command history between sessions is not getting saved. I'm using guake and the history for the session is working fine. I noticed that .bash_history had some commands I executed in "sudo -s" mode and tried the same again and all the commands while in the session got saved so I tried "chmod 777 .bash_history" Now the old commands appear at the start of a session but no new commands are getting saved Thanx in advance

  I am starting to think I simply need to accept a small loss and sell my new ASUS K73E. Because I really don't enjoy computing when I have to deal with Windough$ and this windows 7 64 bit on my new ASUS is even worse than the old machines with XP. I have written to ASUS and they simply say "We don't support Linux" and while Ralink's website says they do support Linux I can't get anyone to tell me what model Ralink card might be in my machine.

• How can I modify the knetworkmanager icon in my kde taskbar?

  - by Joe

  I am using kubuntu 12.04 Precise 64 on my notebook. Almost everything works fine. I would like to modify the colors of the icon(s) used by knetworkmanager to indicate wifi online. Right now, I am using the (default?) Oxygen theme. What I want is to make the online icons some color other than gray - probably black, so the contrast is greater and they're easier for me to see (I use reading glasses.) I found an old article on how to do this, but when I added the icons it mentioned, they were ignored. Where are these icons stored? Can I just edit them with something like gimp to change the colors, etc.? TIA

They do not show up in the additional drivers dialog, and I cannot install any other drivers till these are removed.

• Unable to install ubuntu on a AMD 64 bit system with a AMD Radeon HD 6670 graphics card

  - by Tom Wingrove

  I’ve been running a dual boot system (Ubuntu/Windows7) for two years or so with no problems. I recently built an AMD 64 Bit System, re-installed Windows but when I went to load Ubuntu inside Windows, hit a snag. The screen view during installation became small square blocks of colour, which obviously is a graphics drive problem. I tried various live disks both 32 & 64 bit for, Ubuntu 12.04, 11.10 & 10.10, all but Ubuntu 10.10 had the same problem. Ubuntu 10.10 loaded ok, installed the presented ATI graphics driver as usual but was left with the AMD Unsupported watermark at the bottom right of the screen. The graphics card installed in the computer is an MSI ATI Radeon HD 6670 (in effect an AMD Radeon HD 6670). I am fairly new to linux and while I can install and tweak the OS, I am rather baffled as to what to do. So my question is will an up to date ATI Driver be released in the near future for installation/live disks? Or am I going to have to downgrade my graphics card to use linux? Yours Tom Wingrove

• Is it a bad idea to run SELinux and AppArmor at the same time?

  - by jgbelacqua

  My corporate policy says that Linux boxes must be secured with SELinux (so that a security auditor can check the 'yes, we're extremely secure!' checkbox for each server). I had hoped to take advantage of Ubuntu's awesome default AppArmor security. Is it unwise to run both Apparmor and SELinux? (If so, can this bad idea be mitigated with some apparmor and/or selinux tweaks?) Update 1/28 -- Kees Cook has pointed out in his answer the dead simple reason why it's a bad idea to run both -- the Linux kernel says you can't1. [ 1 More precisely, the Linux Security Modules interface framework is designed for a single running implementation, and does not support more than a single running implementation. ] Update 1/27 -- I've accepted the answer from kenny.r , though I would be happier with some more technical reasons of why this would fail, or examples of actual conflicts that this would cause.

• Cannot activate num pad at all

  - by ubuntico

  I have two accounts on the same machine. Num pad on one account it working normally e.g. I can turn it ON/OFF via NumLock button. The num pad on the other account on this machine stopped working. I cannot turn it on and the buttons work as the NumLock is turned off. This happened without me touching any setting or all. It just happened and now I cannot turn them on no matter what I try. I tried via console command numlockx on - did not help. Tried via UI setting - did not help either. Updated the system from 11.10 to 12.04, did not help either. I really do not know what to do except I make a clean reinstallation of the system which would take 2 days away from me. It's obviously the problem in this account only, as num pad works in the other account. Anyone with a good suggestion?

• How to fix "Disk drive for /boot/efi is not ready or not present"?

  - by N.N.

  After I updated BIOS/UEFI version to 1101 on an Asus P8Z68-V PRO motherboard Ubuntu (11.10) did not boot. After POST all I saw was a black screen with a blinking cursor in the top left corner. I booted an Ubuntu 11.10 live-CD and set the flag for the 20 MB partition before my boot partition to "bios_grub". Then I was able to boot and login. But now every time I boot and Ubuntu loads I get the following message: Disk drive for /boot/efi is not ready or not present. Continue waiting or press s to skip or m for manual recovery. I am able to login if I choose to ignore it by pressing s, but what does this message mean? How can I fix what the message warns about? After logging in I have noticed that /boot/efi is empty. The following forum post speaks of the same issue ubuntuforums.org/showthread.php?t=1893030. Updating to the latest BIOS/UEFI - version 3203, did not have any effect on this issue.

• Will a Wubi install of Ubuntu effect my Windows installation in anyway? [closed]

  Possible Duplicate: What are the benefits of a disk install vs. Wubi? And can I migrate my settings easily? Having never tried a Linux OS before, I want to dabble and take a look at one. Ubuntu seems like a good distro to go with (due to how popular it is) and I want to use Wubi to try it out. I just wanted to know if anything I do while trying out Ubuntu will effect my Windows Installation or the files pertaining to it in anyway? If so, is it potentially Windows breaking?
