• What does a media server need?

  - by DeaDSouL

  I want to buy a new PC to be used as a media server that streams HD movies, music to any wireless device on my network (laptop, desktop, TV, etc.). I was wondering about the PC hardware's specifications that I need to have so that it can work just fine? (It will be wireless) Is there any tutorial showing how it could be done? And the security - how can I secure it? As well as I need it to to host my emails. I mean I have many emails. And sometimes I'm using desktop, sometimes laptop.. so is it possible to make the server store a copy of my emails, attachments, all sent items (whether they were from desktop or laptop)?

• How can I have only two specific keyboard layouts in my system without 'us'?

  - by ??O?????

  I want only two keyboard layouts in my system: us altgr-intl (USA International (AltGr dead keys) ) and gr (Greece), so this is what I've selected in System ? Preferences ? Keyboard ? Layouts. However, every time I begin a new Gnome session (reboot, logout/login), the us keyboard layout is automatically inserted at the top of the list. I created a small script called fixlang that ensures the desirable result: layouts='[us altgr-intl,gr]' # tab between us and altgr key=/desktop/gnome/peripherals/keyboard/kbd/layouts active_layouts="$(gconftool -g $key)" if [ "$active_layouts" != "$layouts" -o "$1" == -f ] then gconftool -t l --list-type=str -s $key "$layouts" fi which I run on login. However, this is a kludge. How can I ensure that Gnome does not mess with my keyboard layout selection?

• switch HDD in laptop

  - by jolly

  the internal hard drive that I have right now in my laptop is coming near its death, clicking for life, so I decided to buy a new HDD. However, I don't want to spend two weeks setting up my system to fit me as it does right now, so I thought that I can make just a hard copy of all the contents to the new disk (using dd). My question is: is it going to work? :-) What are the things that need to be changed, except fstab?

• How do I safely use a virus infected USB drive in Ubuntu?

  - by suhridk

  I have an USB drive which I know is virus infected (an anti-virus on my friend's machine detected it). Unfortunately neither of us know the virus name and I don't want to take the risk of plugging it to my Windows box again. Of course, in all probability the virus affects only Windows. (But I'm not sure) I want to know if I can safely plug the USB into my Ubuntu Lucid laptop and copy the stuff I need from the drive. If there are some precautions I need to follow what would they be?

• Multitouch screen needs two touch points

  - by BloodPhilia

  So, I got a netbook (Some weird China brand) and it has a multitouch screen. I got to installing Ubuntu Netbook 10.10 and I used the mouse and keyboard for that. When I wanted to try the touchscreen, at first it didn't seem to work, then I tried to multitouch, and this is what happens: I put my finger on point A I put my finger on point B, while still holding point A. The cursor now jumps to the location on the screen where point A is touched. I can now use point A to drag the cursor ONLY when holding point B. I can use point B for clicking by tapping, but ONLY when holding point A at the place I want to click. What is going on?

• Double launchers and mouse captured between screens in Twinview configuration

  - by Numpty

  Just upgraded to 12.04 and noticed an extremely annoying issue. While using twinview, there now appears to be a launcher on each screen. Moving the mouse between monitors and over the launcher "captures" the mouse for half a second or so, creating the perception of lag. According to some bug reports I've read it appears that a launcher on every screen is a new "feature". Is there any way I can get rid of the 2nd launcher? It's driving my crazy.

• Click buttons on the mouse stopped working in 12.10

  - by Kushal

  everything was great for a couple weeks after the upgrade, and then all of a sudden, the click buttons on my trackpad (as well as any other USB mouse I would hook up) stopped working. The pointer moves fine, but the clicks don't work. Sometimes the left click doesn't work but right click does, and then some times, neither works. I noticed this would begin when I would accidentally drag some text in a web browser (you know how when you try to move your pointer through the trackpad, but you accidentally tap down and it starts to drag whatever text you've selected on the window), and then you're done. The clicks won't work after that. They would work upon rebooting or logging off and back on, but then after a few minutes of usage, things would go back to being broken again. It happened a LOT when I was trying to play Scrabble on Facebook. I've raised a bug for this, but I haven't heard back anything on it. Here's the bug report: https://bugs.launchpad.net/bugs/1077805 Since the system was unusable this way, I had to remove it and install another OS based on 12.04. Has anyone else faced this issue or does someone know what to do to fix it? I'd go back to vanilla Ubuntu in a heartbeat if this issue can be fixed.

• Why doesn't 12.04 recognize my ATI Radeon X300SE graphics card?

  - by Nomad Zero

  So far everything including the BCM4321 card is working, however, the OEM ATI Radeon X300SE (RV370) is not recognized. When I go into system details the card comes up as unknown. When I run lspci the card shows up as: 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV370 5B60 [Radeon X300 (PCIE)] 01:00.1 Display controller: Advanced Micro Devices [AMD] nee ATI RV370 [Radeon X300SE] I have attempted check Additional Drivers but the card does not show up as needing a driver. So far this is causing the system to run warmer as the processor is doing a bit of the work to run Unity and any full screen videos tend to be rather choppy. Is there an available driver that will fix my issue and what is the install method? I am not scared to run a terminal so no worries there, as long as I have instructions, I can find my way. I am running under 12.04 LTS Kernel 3.2.0-25-generic-pae

• Calibre icon missing from system tray

  - by onvas

  After installing Calibre, I immediately changed the preferences particularly by enabling system tray icon. The program restarted, as required, but the icon didn't appear on my sys tray. So I tried restarting my laptop, but still the same negative result. I have already whitelisted all apps after installing my OS so the problem is likely not that. Is there another solution for this? I'm using 12.04 64-bit on my ThinkPad R61i.

• Dual boot problem - Ubuntu windows 7

  - by Benoit Roberge

  I've been using Ubuntu for a while on my laptop. Recently, I decided to install Ubuntu on my main desktop PC (dual boot with windows 7). I downloaded the Ubuntu installer for windows and installed it (it's now showing Ubuntu in the installed software in my W7 control panel). However, when I tried to boot Ubuntu, after the boot loader and the login screen, my screen splitted in half. I was not able to see the icons and the launcher. I was also not able to do anything. I uninstalled Ubuntu and tried again twice. Same thing/results. Then, I created a partition in W7 and installed Ubuntu on it. Unfortunately, it's doing the same thing. I never saw something like this. Any idea??? Thanks for your help and support.

• Which programming language suits a system that must work without user input

  - by Ruud

  I'm building a prototype of a device that will function much alike a digital photoframe. It will display images retrieved from the internet. The device must start up and run the photoframe. It will have no user interface. The device has a minimal ubuntu installation, but I could install Xorg or whatever needed. Question: I have trouble figuring out which programming language will be suitable. I've just started using Python to try out several things and I am able to download and display images. I guess that means Python can do what I'd like, but is it suitable as a language that will be run on boot without any user interference? Related questions: - How do I set up Linux to start that script automatically? - How to setup a second Python script as a server that runs in the background to retrieve images before they are displayed (Because I think I'll need threading of some sort?)

• dpkg returns error 10 when processing package php5-common

  - by Jesse

  I'm having trouble installing php in 13.04. Seems like the package manager can't (re)configure the php package. I already tried purging every php* package, removing the cache files in /var/cache/aptbut and other solutions I've found but nothing seems to work. Here's the error output: $ sudo dpkg --configure -a Setting up php5-common (5.4.9-4ubuntu2.3) ... dpkg: error processing php5-common (--configure): subprocess installed post-installation script returned error exit status 10 Errors were encountered while processing: php5-common sudo apt-get install -f sudo apt-get install php5-common php5 they all return the same error.

• What "file system" is supported by Windows and Linux?

  - by Skiroid

  I'm setting up a media centre for my living room so that I'm able to watch downloaded films and TV shows on the big screen. The media centre is an old small computer which will have XBMCbuntu 12 installed on it. Right now, the media centre has a 300 GB HDD partitioned into two: 1) Ext4 50 GB (where I'll install the OS) 2) swap 6 GB (swap area) I'm wanting a third partition which I can store all my media on to. This partition will fill the rest of my HDD. Although, I'm stuck on which file system I should set it to. I need the file system to be fully compatible with Windows as I'm going to be removing the HDD from the media centre and plugging it into my main PC, running Windows 8, to transfer the media onto it. I can't transfer over Wi-Fi as the media centre won't be connected to the Internet. My options are: Ext4 journaling, Ext3 journaling, Ext2 journaling, ReiserFS journaling, btrfs journaling, JFS journaling, XFS journaling, FAT16 and FAT32. I know that FAT32 is compatible with Windows but it can only hold files that are 4 GB or less and my films are well over 4 GB. Some more than 10 GB. Is there a file system I can use which is supported by Linux and pops up under Computer in Windows?

• Where can I find a 12.10 DVD image?

  - by NMinker

  While I'm open to buying a DVD from the shop, I'd rather download a DVD image, but I can't find it on the Download page (only the CD images and the option to buying a DVD). I have slow internet where I live, I always relied on the Alternative CD. But now with it gone for 12.10, so I looked for alternatives (DVD Image). So where can I find a DVD image, or is the only way to get one is to buy a DVD from the shop?

• How to configure KDE default settings for a new user of a group?

  - by Adobe

  I'm a sys admin on Kubuntu 11.10 machine. Where do I configure the basic config for a new user (say belonging to group "users")? Edit 1: I want to configure langauages - currently my new users get English and Bulgarian Languages. I want them to get English and Russian - and also to set Alt-CapsLock - to be the input-language-switching-combination. Edit 2: How do I configure things in /usr/share/kde4 When I do kdesudo systemsettings and save configurations - only root settings got changed - not the /usr/share/kde4 ones. Edit 3: New user gets the /etc/skel files controlling bash behaviour-appearence. What about the KDE new user's default files - where are they stored? Edit 4: Oh, I found some hints: kde4-config --path config gives a list of folders (separated by the colon) where KDE looks for configs. My machine responded with: /home/boris/.kde/share/config/ /etc/kde4/ /usr/share/kubuntu-default-settings/kde4-profile/default/share/config/ /usr/share/kde4/config/ /usr/share/desktop-base/profiles/kde-profile/share/config/ It looks like third line is where KDE takes the default options. So I found these zilions of settings - but no GUI way to configure it ((. Edit 5: Finally, I've created a dummy user, configured it, and wrote a script which gives it's settings to a given user(s). The trick - is to chown after one transfered the dot files from one user to another. I've tested it - it works fine.

• I can't click on some things and other problems

  - by Ruben

  I have some issues with my Ubuntu 12.04 . When I open Ubuntu Software Center, the program opens and than just disappears just when it is opened. My Ubuntu 12.04 won't install any updates because of this error in the picture. Worst of all: I can't click on anything except for programs that from Ubuntu: for example I can't browse the internet via Firefox or Chromium... I can't click on folders. I can't click on things in my Thunderbird mail program. But I can click on Update manager for example... It is just clicking that doesn't work, when I try 'clicking' something with using the tab-button and enter I can click on something - in every case. But that's just too annoying to do. Oh sorry guys I had some screenshots that illustrate the problems, but I can't get them off the 'problem pc ubuntu 12.04' about which I am talking... it's so sad

• How do I debug an overheating problem?

  - by Tab

  Hello guys. I have a problem with my Laptop (Dell Inspiron 1564 Core i5 4GB Ram VGA ATI Mobility Radeon HD 4300 running Ubuntu 10.10 32bit). It shuts down abruptly without even a lag in the application I am working with before shutdown. I think it's overheating problem. Actually the laptop is hot all the time when I am running Ubuntu. When I switch back to windows, even with intense load it won't shutdown or show any problem as long as I keep proper ventilation (when the air openings are blocked it does the same). Actually on Ubuntu i don't usually do things that need much CPU power, usually surfing internet, coding web pages and sometimes playing with python and ruby. I am not enabling desktop effects so no GPU load except the normal GNOME gui. Now as I am writing the Processor load in the panel monitor applet is 0%, Memory 11% by programs, 22% by cache. And i have CPU Frequency monitor for each of the 4 cores set to 1.20 Ghz (the lowest possible value, i am not sure if this applet does really limit CPU usage). Running sensors in terminal gave me temp1: +26.8°C (crit = +100.0°C) temp2: +0.0°C (crit = +100.0°C) hddtemp /dev/sda at the terminal gave me /dev/sda: WDC WD3200BEVT-75ZCT2: 46°C All that fine but the laptop is Really hot i can feel it in the keyboard, mouse pad is painful to touch, and the fan is always spinning. I am also placing 2 small fans running on USB under the laptop right now and the laptop is lifted over the fans so it's well ventilated. When I am running windows it doesn't get that hot except when there is a really big load on the CPU and this is keeping me away from using Linux for everyday tasks. Actually I don't care much for speed as I can deal with low speed it's not going to shutdown abruptly. So please if you can help me and tell me what are the possible causes, where should I start ?

• Clock drift even though NTPD running

  - by droffo

  I'm having a problem with the clock drifting on my PC. I'M running Ubuntu 10.10 on an somewhat crusty IBM e-server (1.5GB RAM, 2.4GHz CPU) ntpd is running (started at run level 2) servers are defined: server 1.us.pool.ntp.org server 2.us.pool.ntp.org server 3.us.pool.ntp.org server time.nrc.ca server ntp1.cmc.ec.gc.ca server ntp2.cmc.ec.gc.ca server wuarchive.wustl.edu server clock.psu.edu Looking at the log file, it would seem that the ntp daemon is running, but the system clock never seems to be set, however. If I manually set the time from a Casio "atomic" watch, the date/time displayed by the Clock applet drifts out of sync over time. Looking at the log file (below) it would seem the ntp daemon started ok and is running. So I am totally flummoxed right now :-( Here's a copy of my ntp.log file.

• "Unable to install GRUB in /dev/sda" when installing GRUB

  - by vicban3d

  I recently bought a shiny new Lenovo Yoga 2 Pro and I want to dual boot it with Ubuntu for studying purposes. Its built-in OS is Windows 8.1 and it has a 256GB SSD. I've made a separate 90GB partition just for Ubuntu and a live USB to install it. The first time everything seemed to work great, I solved the wifi issued by blacklisting ideapad_laptop, the installation went flawlessly and Ubuntu worked fine. When I got up the next morning and turned on my laptop it booted into Windows right away without ever showing the GRUB menu. So I tried to reset, and checked my partitions with the Disk Manager and everything looked fine. Since I couldn't find a solution online I went ahead and formatted the partition to try and install again. This time and every time since, the installation was aborted and I got a fatal error saying: Unable to install GRUB in /dev/sda Executing `grub-install /dev/sda` failed. This is a fatal error. Can anyone please suggest a solution to this problem? If any further information is needed I would be happy to provide it. Thanks. When installing I get the following in details: ubuntu kernel: [ 1946.372741] FAT-fs (sda2): error, fat_get_cluster: invalid cluster chain (i_pos 0). ubuntu grub-installer: error: Running 'grub-install --force failed.

• No enable mobile broadband option

  - by noboot

  I just migrated from Wubi to actual dual booting Ubuntu and Windows 7 my machine is an Aspire 4750G. When I had (Wubi) Ubuntu 12.04 LTS 64-bit the network applet included the "enable mobile broadband" option. Now, I am using Ubuntu 12.04 LTS (32-bit) actual install as the 64-bit does not work. And my problem is that it does not show the "enable mobile broadband" option. This is so weird considering that I did not encounter the same problem in Wubi based installation.. Kindly help.. I have managed to connect to the internet via Sakis3G Script, still I find the previous method a lot more convenient..
