• Finding links among many written and spoken thoughts

  - by Peter Fren

  So... I am using a digital voice recorder to record anything I see important, ranging from business to private, from rants to new business ideas. Every finalized idea is one wma-file. I wrote a program to sort the wma-files into folders. From time to time I listen to the wma-files, convert them to text(manually) and insert them into a mindmap with mindmanager, which I sort hierarchically by area and type in turn. This works very well, no idea is being lost, when I am out of ideas for a special topic, I listen to what I said and can get started again. What could a search system look like that finds links between thoughts(written in the mindmap and in the wma files) or in general gives me good search results even when the keyword I searched for is not present but a synonym of it or related topic(for instance flower should output entries containing orchid aswell, even if they contain orchid but not the very keyword flower). I prefer something ready-made but small adjustments to a given system are fine aswell. How would you approach this task?

• Installing Ubuntu 12.04 on a single GPT SSD which contains Windows 7

  - by Gary

  I recently bought a brand new 64 bit PC with a (ASUS) motherboard that supports UEFI and a GPT formatted 240Gb SSD, which contains Windows 7 in the first of 3 (80Gb) partitions. When the system arrived, it booted into Windows 7 like a dream, with no problems. I did not originally want Windows, but the manufacturer does not work with Linux (of any flavour), so I thought I would install Ubuntu into the second partition and dual boot. I downloaded the 12.04 64bit version and proceeded to install. Having selected to 'install', the screen became corrupted, with multicoloured garbage across the middle third of the screen !! So, I rebooted and --- MISSING OPERATING SYSTEM !!! The only way I can now get into Windows is via Super Grub2. First question - what went wrong ? 2nd - Will Ubuntu install on a GPT disk partition ? 3rd - Will it install alongside Windows 7 without screwing the boot mechanism ? 4th - How do I do it ? I have scoured the internet looking for appropriate answers and found NONE ! Please help.......

• How to retain secondary hard drive mounts at reboot and keep shares?

  - by Tom

  I'm running Ubuntu 12.04. A second hard drive connected to this computer does not mount when the computer boots. Additionally, I have set up the drive to be shared but the share is not retained, the share is lost after each boot. My main system drive and a removable drive mount OK and shares remain between boots. Additional information follows: D2Linux sda1 is the secondary hard drive L-Freeagent sdc1 is the removeable drive Here is the contents of fstab immediately after booting (D2Linux /dev/sda1 not yet mounted): '# /etc/fstab: static file system information. ' '# ' '# Use 'blkid' to print the universally unique identifier for a ' '# device; this may be used with UUID= as a more robust way to name devices ' '# that works even if disks are added and removed.

• DPKG errors after upgrade to 12.10

  - by James Wulfe

  So I was doing fine then i upgraded my system to 12.10 and now i cant get my system to update all of its packages properly. no matter what i do, cleaning apt cache, manual install using dpkg, etc, i just cant get them to install. what is happening here and how do i fix this. if i would have thought 12.10 would be this much of a hassle i would have never upgraded..... here is a sampling of the code that returns from "apt-get -f install" Preparing to replace usb-modeswitch-data 20120120-0ubuntu1 (using .../usb-modeswitch-data_20120815-1_all.deb) ... /var/lib/dpkg/info/usb-modeswitch-data.prerm: 4: /var/lib/dpkg/info/usb-modeswitch-data.prerm: dpkg-maintscript-helper: Input/output error dpkg: warning: subprocess old pre-removal script returned error exit status 2 dpkg: trying script from the new package instead ... /var/lib/dpkg/tmp.ci/prerm: 4: /var/lib/dpkg/tmp.ci/prerm: dpkg-maintscript-helper: Input/output error dpkg: error processing /var/cache/apt/archives/usb-modeswitch-data_20120815-1_all.deb (--unpack): subprocess new pre-removal script returned error exit status 2 /var/lib/dpkg/info/usb-modeswitch-data.postinst: 7: /var/lib/dpkg/info/usb-modeswitch-data.postinst: dpkg-maintscript-helper: Input/output error dpkg: error while cleaning up: subprocess installed post-installation script returned error exit status 2 Errors were encountered while processing: /var/cache/apt/archives/network-manager_0.9.6.0-0ubuntu7_i386.deb /var/cache/apt/archives/pcmciautils_018-8_i386.deb /var/cache/apt/archives/unity-common_6.10.0-0ubuntu2_all.deb /var/cache/apt/archives/whoopsie_0.2.7_i386.deb /var/cache/apt/archives/usb-modeswitch_1.2.3+repack0-1ubuntu3_i386.deb /var/cache/apt/archives/usb-modeswitch-data_20120815-1_all.deb E: Sub-process /usr/bin/dpkg returned an error code (1) It is also just these 6 packages only. no other packages have given me this kind of trouble. well i should say as of now. It was just 5, but them i got an update for unity, and now unity-common is added to the trouble makers. which prevents me from further upgrading the actual unity package as this package is a dependancy.....

• Too much I/O in the morning ?

  - by steveh99999

  Interesting little improvement on a SQL 2005 system I encountered recently….. Some background - this system had a fairly ‘traditional OLTP’ workload ie  heavily used during day – till around 9pm, then had a batch window for several hours, then not much activity in the early hours of the day, until normal workload resumed the following morning. Using perfmon, I noticed that every morning, we would see a big spike in SQL Server I/O when the application started to be used... As it was 2005 I decided to look at what tables were in cache before and after the overnight batch processing ran… ( using DMV equivalent of dbcc memusage that I posted earlier). Here’s what I saw :-     So, contents of data cache split fairly evenly between my 'important/heavily used' tables.   After this:- some application batch processing,backups, DBCC checks and reindexes were run.  A fairly standard batch I'd suggest. Cache contents then looked like this :- Hmmmm – most of cache is now being used by a table I’ve described as ‘unimportant’. Why ? Well, that table was the last to be reindexed…. purely due to luck, as  the reindexing stored procedure performing a loop in alphabetical order through all application tables...  When the application starts to be used again – all this ‘unimportant’ data has to be replaced in cache by data that is heavily used… So, we changed the overnight reindex scripts –  the most heavily accessed tables are now the last to be reindexed. Obvious really, but we did see a significant reduction in early-morning I/O after changing the order of our reindexing.

• Upgrade to 12.04 results to empty Dash, no date & time either on the top panel

  - by Nicolas

  I've upgraded from Ubuntu netbook remix something to 12.04 LTS, and I've got two issues. (Got an Asus eeePc 32bits, Intel 945GME x86/MMX/SSE2 and Intel Atom CPU N270 @ 1.6Ghz x2) Nothing in the Dash. Only the "home" tab, other tabs are missing. No search results whatsoever. Missing elements in the system panel, privacy and date & time. No date & time on the right corner either. I've tried to reset unity with the terminal but the process was a whole mess full of errors. It did show date & time in the system panel (not on the top-right corner) while the process was going on in the terminal. But then it was such a mess (no more icons on the right corner amongst other things), and the process wouldn't complete, so I had to reboot the computer and get Unity as before, still no date & time and privacy.

• A fresh install and clean up?

  - by wdypdx22

  I started with Ubuntu around 3 years ago and have been a dedicated user ever since. During that time I tried out lots of apps, themes, etc. And, I've updated every version as it has come along so now I'm running Lucid. Basically, my system has gotten sort of "messy" and I'm planning a vigorous clean up and a fresh install. My /home is on a separate partition from everything else, so I can preserve that. I want to find and remove unused, unneeded apps (which I pretty much understand how to do). Also, I want to get back to the default desktop theme and build back up from there. And other messes surely exist. So, my question is, What is a good, logical plan to clean up and freshly reinstall my system? (One note is that I have found many links in searches on this issue. There are many links on this topic and many are out of date. So, it's gotten rather confusing to say the least.) Thanks.

• Problems with wired ethernet connection Ubuntu 11.10

  - by Andrew Fielden

  After some partition shuffling, I've got a problem on my 11.10 system. The wired ethernet interface fails to come up, although the wireless interface is working. I'm using NetworkManager. I thought this may be a problem with NetworkManager, so I checked the config files, which look ok. I then tried re-installing the package, but this didn't resolve the issues. I'm not sure at this point if the problem is due to software configuration, or a hardware problem. I've also tried the cable in other router ports, but same problem. The symptoms are:- System settings - Network reports that the cable is unplugged (it isn't) ifconfig reports the following eth0 Link encap:Ethernet HWaddr f0:4d:a2:a2:a7:fe UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:10 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:792 (792.0 B) TX bytes:0 (0.0 B) Interrupt:46 Base address:0xe000 My /etc/network/interfaces file has the following: auto lo iface lo inet loopback My /etc/resolv.conf file has the following: # Generated by NetworkManager The router's red light is on for this port dmesg reports ADDRCONF(NETDEV_UP): eth0: link is not ready

• Ubuntu 12.10: Installing proprietary Nvidia driver causes freeze at boot

  - by Greg

  Ok, so I just installed Ubuntu on my laptop, and I immediately encountered an issue: the HDMI audio output won't work. Yes, I know about the sound settings thing where you have to select the HDMI option, but even when it's selected I get no sound out of the TV I'm hooking it up to. This is a dealbreaker for me, because my laptop speakers are terrible, it's one of the big reasons I use my TV monitor. So I decided to work on solving the problem by upgrading my Nvidia drivers. I switched to one of the propriety drivers offered in that software updating utility that comes with the OS, the one option that said (tested). Viola, sound over the HDMI is now working. Unfortunately, this now brings me to my next problem: when I reboot Ubuntu with this or any other proprietary driver installed, it freezes when it tries to load my desktop. As in I can see my wallpaper, but no icons or options of any kind. The system is totally frozen, and gives me one of those "we've experienced an error, do you want to report it messages." So there's my bind. I need HDMI audio out, that's a total dealbreaker for me, but installing the drivers that give me that capability crash the system. Does anyone have any idea what's causing this

• USB mass storage couldn't get mounted

  - by revo

  It's my android phone SD card which was indicated damaged by android yesterday night, out of the blue! I put it directly to a USB port with a USB SD card holder case, so in that way I can recover it with TestDisk, which I had experienced before on a similar situation. I also noticed that there is a change in file system and capacity: File System : RAW Capacity : 0 (unknown capacity) Also TestDisk doesn't show it on its partitions list. A 2 GB SD card is not that important in price but I've a lot of files and medias which I need them. Used a mini card reader, TestDisk displayed it on its list but a quick search and or a deep search doesn't have any results No partition found or selected for recovery and then I should quit the program.

• please help me understand libraries/includes

  - by fiftyeight

  I'm trying to understand how libraries work. for example I downloaded a tarball and extracted it. Now I do "./configure", it searches in pre-defined directories from what I understand for certain library files. What does it do then? it creates a makefile, and the makefile contains the paths to these libraries? than I do "make", it complies the source code and hard-codes the locations of the libraries? am I correct? I do not really understand if libraries are files with pre-defined paths or the OS somehow gives access to the libraries through system calls. another example, I complied something on my computer than moved it to a remote server, the executable needs mysql libraries to work, the server has mysql but for some reason when execute the file it tells me "can't find libmysqlclient.so.16". is there a solution for this? is there a way to know where is tries to locate this file or give it another path? I can't compile it on the server since it has no compiler and I don't have root access to install packages last question is if in the sequence "./configure","make","make install" the "make install" command is the only one that actually puts files outside the directory in which these files reside? if for example the software will be installed in /usr/local/ is the "make install" command the only one that will require "sudo" before it? let me see if I got it correctly: "./configure" creates the Makefile according to the location of various files on your system. "make" compiles the source code according to this makefile. and "make install" moves the files to their appropriate location. I know this has been very long I thank anyone who had the patience to read my question :)

• All files on automounted NTFS partition are marked as executable

  - by MHC

  I have set up an NTFS partition to automount via fstab: # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sda7 during installation UUID=e63fa8a2-432f-4749-b9db-dab328807d04 / ext4 errors=remount-ro 0 1 # /boot was on /dev/sda4 during installation UUID=e9ad1bb4-7c1f-4ea9-a6a5-799dfad71c0a /boot ext4 defaults 0 2 # /home was on /dev/sda8 during installation UUID=eda8c755-5448-4de8-b58c-9cb75823c22d /home ext4 defaults 0 2 # swap was on /dev/sda9 during installation UUID=804ff3a7-e5dd-406a-b63c-e8f3c635fbc5 none swap sw 0 0 #Windows-Partition UUID=368CEBC57807FDCD /media/Share ntfs defaults,uid=1000,gid=1000,noexec 0 0 As you can see I have added the noexec bit to the configuration. Why? Because any file I create on or move to the partition is automatically marked as executable. The problem is that there is no way of changing that through nautilus. I cannot uncheck the "Allow executing file as program" option. The noexec option doesn't help, unfortunately. It only prevents nautilus from displaying the "run" or "read" dialog but doesn't change the executable flag. Is there any way I can fix this?

• Boot ubuntu 12.04 in 3D - nomodeset quiet splash install

  - by rahi

  I would like to enable 3D in Ubuntu 12.04. I recently tried to install ubuntu on a new computer. When the installation was complete and I rebooted the machine, I could only see a blank screen. After some searching, I followed this tutorial which instructed me to boot with "nomodeset" enabled. I choose this on the USB I was installing ubuntu 12.04 from. Fortunately, the ubuntu installation on the new computer was successful. When I tried to change the size of the unity launcher icons, I did not see that option (as I see on my other computer running ubuntu 12.04). I tried installing MyUnity and it told me that the computer I had just installed 12.04 to was running in 2D. To my knowledge. all the software is up to date (as I ran the Software Updater). In addition, when I look for Additional Drivers, I see a message that says "No proprietary drivers are in use on this system". When I look under System Details Graphics, I see the Driver as "VESA:Intel Sandybridge/Ivybridge Graphics. When I hold the shift key on when my machine boots up, and type "e" on the Grub menu, I see the following towards the end, "nomodeset quiet splash $vt_handoff". Does this have anything to do with the plain 2D ubuntu 12.04 experience? Again, what I'd like to do now is get the 3D experience on my new machine running 12.04. Please let me know if you need more information.

• ASP.NET: Serializing and deserializing JSON objects

  - by DigiMortal

  ASP.NET offers very easy way to serialize objects to JSON format. Also it is easy to deserialize JSON objects using same library. In this posting I will show you how to serialize and deserialize JSON objects in ASP.NET. All required classes are located in System.Servicemodel.Web assembly. There is namespace called System.Runtime.Serialization.Json for JSON serializer. To serialize object to stream we can use the following code. var serializer = new DataContractJsonSerializer(typeof(MyClass)); serializer.WriteObject(myStream, myObject); To deserialize object from stream we can use the following code. CopyStream() is practically same as my Stream.CopyTo() extension method. var serializer = new DataContractJsonSerializer(typeof(MyClass));   using(var stream = response.GetResponseStream()) using (var ms = new MemoryStream()) {     CopyStream(stream, ms);     results = serializer.ReadObject(ms) as MyClass; } Why I copied data from response stream to memory stream? Point is simple – serializer uses some stream features that are not supported by response stream. Using memory stream we can deserialize object that came from web.

• 12.0.4.3 - Missing Battery Icon, auto Suspend not working, Keyboard shortcuts volume up/down no longer working

  - by Navraj

  Problems I am experiencing: Battery Icon not showing up unity bar (top right corner). Volume Up/Down/Mute not working. Bluetooth hot keys described above also not working.Brightness up/down keys on this keyboard no longer working (apple wireless keyboard) Laptop no longer suspends when lid is shut. I have to go to 'power' button on top right corner and click on 'Suspend' All was working flawlessly until I did the following: I have recently upgraded to Nvidia propriety driver version 319 {version recommended}. Installed Xscreensaver and then removed it and went back to default screensaver. Done a system update (1st since installing) and now currently running: Linux 3.8.0-32-generic #47~precise1-Ubuntu SMP Wed Oct 2 16:19:35 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux NOTE: Base system was ubuntu 12.04.3 installed from ISO however lsb_release reports "No LSB modules are available" 4.installed psensor. I have check power setting (via Settings) and power setting via dconf-editor and set to recommended settings as described in posts detailing solution to this problem. - I have disabled 1) Nvdia settings at startup and 2) psensor at startup but this does not help. I am using an HP DV7 with 2GB Nvidia card. Not using any fancy graphics features. Recommendations? Thanks.

• Microsoft Access as a Weapon of War

  - by Damon

  A while ago (probably a decade ago, actually) I saw a report on a tracking system maintained by a U.S. Army artillery control unit.  This system was capable of maintaining a bearing on various units in the field to help avoid friendly fire.  I consider the U.S. Army to be the most technologically advanced fighting force on Earth, but to my terror I saw something on the title bar of an application displayed on a laptop behind one of the soldiers they were interviewing: Tracking.mdb Oh yes.  Microsoft Office Suite had made it onto the battlefield.  My hope is that it was just running as a front-end for a more proficient database (no offense Access people), or that the soldier was tracking something else like KP duty or fantasy football scores.  But I could also see the corporate equivalent of a pointy-haired boss walking into a cube and asking someone who had piddled with Access to build a database for HR forms.  Except this pointy-haired boss would have been a general, the cube would have been a tank, and the HR forms would have been targets that, if something went amiss, would have been hit by a 500lb artillery round. Hope that solider could write a good query :)

• Removed Java replaced with newest "Sun Java", disc won't boot, and won't let me re-install grub using boot repair disc

  - by Al Rowe

  Had a minor problem with my Stock market platform. Set-up screen would freeze program. Called their tech support, got their "Linux guy", who advised remove all Java and replace, not with synaptic version, but newest Sun Java. After removing, computer auto rebooted, and went to blue mem-test screen. Showed no errors, but couldn't get back in. Tried two versions of boot repair disc from iso (checked md5sum, showed good.), but fix aborted, giving apt-error detected. Opened a terminal and typed (or copy/paste): sudo chroot "/mnt/boot-sav/sda1" apt-get -f install. My system is Ubuntu 12.04. Had a few very minor issues from install, all fixed. Also added some of my favorite gnome tricks just to make life easier, but none that could have caused this. Added script to add shortcuts to desktop, open terminal in any menu from inside it, access root terminal, etc. System was firewalled and using avast antivirus (o.k., I'm paranoid. Used to do Windows sys-op and security.) But relative newbie to Linux.

• Copying photos from camera stalls - how to track down issue?

  - by Hamish Downer

  When I copy files from my camera (connected via USB) to the SSD in my laptop a few files get copied and then the copy stalls. I'm not sure why, any ideas or things to investigate appreciated, or bug reports to go and look at. I have read this answer - the camera (Canon 40D in case that matters) mounts fine using gvfs. I can see the photos in Nautilus, or in the terminal (in /run/user/username/gvfs/... ) and I can copy a few photos, but not many. Using the terminal or Nautilus the process hangs until the camera goes to sleep. Digikam fails to copy any at all, as does Rapid Photo Downloader. Shotwell did manage it in the end, but that is very much a work around for me. I have disabled thumbnail generation by nautilus. Load average stays about 1 while this is happening, while CPU usage is half idle, half wait (and a little user/sys for other programs). None of the programs at the top of the cpu list in top are related to copying photos. There is not much in the logs - from /var/log/syslog Dec 2 16:20:52 mishtop dbus[945]: [system] Activating service name='org.freedesktop.UDisks' (using servicehelper) Dec 2 16:20:52 mishtop dbus[945]: [system] Successfully activated service 'org.freedesktop.UDisks' Dec 2 16:21:24 mishtop kernel: [ 2297.180130] usb 2-2: new high-speed USB device number 4 using ehci_hcd Dec 2 16:21:24 mishtop kernel: [ 2297.314272] usb 2-2: New USB device found, idVendor=04a9, idProduct=3146 Dec 2 16:21:24 mishtop kernel: [ 2297.314278] usb 2-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 Dec 2 16:21:24 mishtop kernel: [ 2297.314283] usb 2-2: Product: Canon Digital Camera Dec 2 16:21:24 mishtop kernel: [ 2297.314287] usb 2-2: Manufacturer: Canon Inc.

• JavaScript 3D space ship rotation

  - by user36202

  I am working with a fairly low-level JavaScript 3D API (not Three.js) which uses euler angles for rotation. In most cases, euler angles work quite well for doing things like aligning buildings, operating a hovercraft, or looking around in the first-person. However, in space there is no up or down. I want to control the ship's roll, pitch, and yaw. To do that, some people would use a local coordinate system or a permenant matrix or quaternion or whatever to represent the ship's angle. However, since I am not most people and am using a library that deals exclusively in euler angles, I will be using relative angles to represent how to rotate the ship in space and getting the resulting non-relative euler angles. For you math nerds, that means I need to convert 3 euler angles (with Y being the vertical axis, X representing the pitch, and Z representing a roll which is unaffected by the other angles, left-handed system) into a 3x3 orientation matrix, do something fancy with the matrix, and convert it back into the 3 euler angles. Euler to matrix to euler. Somebody has posted something similar to this on SO (http://stackoverflow.com/questions/1217775/rotating-a-spaceship-model-for-a-space-simulator-game) but he ended up just working with a matrix. This will not do for me. Also, I am using JavaScript, not C++. What I want essentially are the functions do_roll, do_pitch, and do_yaw which only take in and put out euler angles. Many thanks.

• Radeon HD 6850 VMware 3D Support?

  - by Matt

  I'm a new Ubuntu user (new to all of linux actually). I've installed Ubuntu 11.10 x64 and have been enjoying it, but I wanted to see how it would perform using VMware for small time gaming since I find dual booting too much of a nuisance to even bother using Ubuntu at all (sorry!). I have an Asus EAH6850 DirectCU Radeon HD 6850 graphics card and I've installed the additional ATI/AMD proprietary FGLRX graphics driver, but when I open a Windows XP 32bit machine I installed through VMware, I get this message: "The GPU driver currently installed on this host may cause issues with VMware products. If you notice any issues please disable the 3D support in the affected virtual machines." I still have 3D capabilities in the VM but they are very very choppy even running the DX tests (the spinning cube). I've seen people on youtube and other forums saying that since the new 3D acceleration in VMware 8 gaming is very possible through VMs (and I've seen them running the DX tests with the spinning cube very smoothly). I'm wondering if my graphics card isn't fully supported or if I have installed it wrong. Also when I check system info (on the host Ubuntu machine) it says "Graphics VESA:BARTS" Should my Radeon HD 6850 be showing up there? The rest of my basic system info i5 2500k 8GB 1600MHz memory Guest is running with access to all 4 cores of processor and 3gb memory assigned.

• Setting up Cluster Configuration using an existing web server as a Primary Node?

  - by RapidWebs

  Thanks in advance for any help which is issued! I am having a slight issue, and need help with the decision making process when it comes to setting up my Cluster Configuration, consisting on a line of Ubuntu Servers (12.04). We currently have a Primary node, which resides in the US within a Datacenter, but we are going to be using this for all serious bandwidth and resource intensive websites, and through a configuration of Virtualmin + Webmin, will be setup as a sort of pseudo-cluster, using Virtualmins Cluster Modules. Anyways, on to the issue: We also have a business line setup locally, with three servers. here are their specs: Intel P4 2.4 ghz, 1GB Ram, 110 gb sata, Ubuntu 12.04* AMD 1.3 ghz, 512MB Ram, 20 GB IDE P3 Xeon 800mhz (dual physical processors), 1GB Ram, 3 * 25 GB Raid Configuration (one in use for host operating system). The first machine is currently IN USE and is serving virtual hosts off a sub-domain. My question is this: How can I integrate the Secondary node (which will be the Primary node per say, in this smaller configuration...) which is currently in use, into the cluster configuration w/ the other two servers for: Sharing Resources Redundancy (HA?) NFS /w the two Raid Disks without having the FORMAT the secondary node, and start fresh moving all my services in to a DRBD network drive or something similar, and than restoring all active virtualmin's Virtual hosts. the idea is that I want minimal downtime to people currently being served from server2.mywebsite.com, and from what I understand, all services need to be on a NFS so that they can be mounted on demand and accessed from the other machine taking over (i.e. Heartbeat + DRBD Config.) but my issue is that i already have all these services installed to their default directory structure: how can i most easily setup this NFS and HA system, move all my desires services to this new drive, and do it with minimal down time, and without breaking Virtualmin and everything else on my server? even just some pointers, a thread i could read, or a step by step check list or run down of commands i could issue to get started would be great! thanks!

• How do I get Graphics drivers / bluetooth / card reader working on an Acer Aspire V3-571G?

  - by Adam

  A couple of days ago I bought an Acer Aspire V3-571G laptop without a system installed on it. The only thing that was there was Linux Linpus. I created a bootable CD with Ubuntu 12.04 64-bit - I read that my processor was 64 bit and that it might be a good configuration for my gear (I'm not especially fluent with all the computer stuff, still trying to learn) and replaced Linpus with Ubuntu. Everything seemed to work fine, but there're few exceptions to that which came pass my way. My bluetooth doesn't work. It seems to be switched on, but when I check my system settings the button is actually off, and I can't drag it 'perminently' to the 'on' position. Tried a couple of commands I found on the net, none of them helped and there was no word whatsoever in my BIOS settings about enabling bluetooth. My card reader has some serious problems with copying more than one file at a time. I tried to put some music on my phone through a MicroSD card adapter (because my bluetooth doesn't work) and it got stuck every single time I copied an album on it. I'm not sure if all my drivers were properly installed, so I checked in the terminal if it could tell me sth about my graphics. typed: sudo lshw -c display and what i got was: *-display UNCLAIMED description: VGA compatible controller product: NVIDIA Corporation vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller cap_list configuration: latency=0 resources: memory:b2000000-b2ffffff memory:a0000000-afffffff memory:b0000000-b1ffffff ioport:2000(size=128) *-display description: VGA compatible controller product: Ivy Bridge Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:44 memory:b3000000-b33fffff memory:c0000000-cfffffff ioport:3000(size=64) As I said I'm no expert and not english-speaking generally, but it doesn't seem to be right.
