• 12.04 Taking forever for no apparent reason

  - by Sam

  First off, I'd just like to say how much I'm loving Ubuntu so far. It's one of my first steps into Linux, but so far it's blown away Windows in almost every regard. Now, onto my problem. My brothers have some old Dell Dimensions that are barely clinging to life. They were both running XP Home Premium. The 2400 installed just fine, no issues at all. Now, the other computer, the 3000 isn't clearing the screen with the Ubuntu logo and the pulsing dots. I've tried multiple discs, including the exact same one that gave me no issue in the other computer, and I'm at a loss. Does anyone have any suggestions as to where the problem might lay? They're both 32 bit Intel processors, and it's the correct version of Ubuntu. Is it a bad disc drive? Hardware incompatibility? Thanks for any assistance that can be provided.

• Virtualbox crashes quite often in Windows 8

  - by user1776158

  I just installed Windows 8 on my computer. I got the ISO and the product key from my university so the software itself is sound. I use alot of virtual box. And ever since I moved to Windows 8, I have noticed that virtual box crashes more often. In particular, it is very very bad at opening multiple guests. My CPU usage will be at like 20% and I only have 3 guests open and my entire computer just freezes. Cursor and all. In Windows 7, I was able to open like 6 (not that I ever needed to) and really push my CPU. I havent experience any other issues with Windows 8 yet. Has anyone encountered this? Thanks!

• Dell Inspiron 1501 battery no longer "recognized"

  - by mwalling

  My parents were on vacation last weekend and franticly called me saying that they couldn't get their Inspiron 1501 to boot anymore without the BIOS whining about the battery. Before this happened, they said the "battery went dead with negligible pre-warning". On bootup, the computer says: WARNING: The battery cannot be identified. This system will be unable to charge this battery. With options to enter the BIOS or continue booting. I got to look at the machine last night. The battery still holds a charge, and will recharge. Windows detects it as a DellPY9617 battery manufactured by "DynaPack". I didn't get the BIOS revision, but the machine's ship date was 7/21/2007. The recommendations I could find on the internet varied from "discharge the battery completely" to "your computer is too old" to "update the BIOS", and wanted a more specific answer before doing something drastic.

• Should a software developer get a yearly equipment budget?

  - by CrazyDart

  I am looking at a new position with a new company. I have talked to some people in the past (in general, not at this company) that they had been given a yearly budget to buy new computer stuff to keep up to date. Now why I feel this question is worth asking here is that Joel comes right out and says an employer should pay for the best equipment money can buy... within reason of course. From The Joel Test: 12 Steps to Better Code 9. Do you use the best tools money can buy? Writing code in a compiled language is one of the last things that still can't be done instantly on a garden variety home computer... Top notch development teams don't torture their programmers. Even minor frustrations caused by using underpowered tools add up, making programmers grumpy and unhappy. And a grumpy programmer is an unproductive programmer... Does anyone know if the industry has such a standard to offer an allowance or budget? I have never worked for a company like this, but I am thinking I should toss this in the ring for negotiations. Seems reasonable. How do bigger companies like MS, Google, and Apple handle this? If you say yes, give a range... I have been told numbers from $5k to $10k. Seems high to me, but hey I would gladly take it.

• Cannot delete movie on iTunes for iPhone 4?

  - by Jian Lin

  I was on vacation and took some videos, and now the iPhone 4 memory is near full. So I tried to delete other experimental movies I made using Handbrake, so that I can take more video or photos, but if I plug the iPhone 4 into my Notebook computer, I can seem to delete it on iTunes? Maybe because the computer I sync with the iPhone 4 is at home (a desktop), but not with me on vacation. I can't delete it on iTunes, can't delete it on iPhone itself. I am stuck during the vacation, or is there a way to handle it?

• How to set the network profile of Windows 7 via group policy?

  - by Ricket

  We are deploying client computers and in testing noticed that the first time the user logs into the computer, it asks them if the location is a home, work, or public location. We are worried that some users in our workplace might misread it (or not read it at all) and click Public, thus likely denying our access to the computer and messing up security settings and such. Can we set our network to be a "Work Network" location via group policy or some other mechanism of our Windows Domain so that the user is not prompted when connected to our network? Also these are laptops, so we don't want every network they connect to be set as work network, and we have several access points (wired and three wireless) which our users often switch between so I'm not yet sure if it reprompts with each access point but I have the feeling it will, and I would like all of these to be set to the Work profile type.

• How to merge several detached signatures from different people into one?

  - by Petr Pudlák

  A group of people wants to publish a file and they all want to digitally sign the file as different recipients of the file will have different chains of trust. For simplicity, it's desired that there is only one detached signature file with all the signatures, so that the recipients don't need to check them one by one: foo.tar.gz foo.tar.gz.sig However, for security reasons, every person needs to perform the signing on their computer, it's not possible to create the combined signature by having multiple private keys on one computer and performing the operation with one command. Is it possible with GPG to somehow merge detached signatures of a file from multiple participants?

• install clamav from surceforge

  - by maria

  I'm using Ubuntu 10.04. I'm affraid I've installed a virus on my computer (I've clicked a link which was a virus), I'd prefere to check if everything is fine. I've installed clamAV using Synaptic. The installed version was 0.96.5, while the most recent version is 0.97.6. When I was trying to update virus database, I got a warning that the version of clamAV I'm using is outdated. Since I didn't know how to update the software by Synaptic or apt (both show the installed version as the newest) I've uninstalled all and downloaded the recent version from sourceforge. I've unpacked the tar.gz archive, entered the folder but when I type ./configure I'm getting the message: configure: error: Please install zlib and zlib-devel packages When I type sudo aptitude install zlib zlib-devel The terminal output says there is no such packages (there is no package zlib-devel and there is many packages which name contain zlib). I suppose the link contained probably the Windows virus, but I'd prefere to make sure there is nothing in my computer. As well as I'm not sure if the virus, even without harming my system, can send itself to my e-mail contacts or not.

• Upgrading MacBookPro

  - by moray95

  I'm using a Late 2011 13" MacBook Pro with an Intel i5 @ 2.4 GHz and 4 GB 1333 MHz ram. The computer has started to get older. I was going to upgrade the ram but since Mavericks come out, the ram problem just went away and now, it started to get slower and slower. So I was thinking of upgrading my ram to at least 8GB and my CPU. I have two question about that. As I have 1333Mhz rams installed by default, the motherboard should not support 1666Mhz rams. But can I use 1666 Mhz ones and if I can will it make any difference? Also is it possible to upgrade the CPU of my computer? If yes how can I find a CPU compatible with the other components?

• Wake-On-Lan - is it possible to access boot menu?

  - by truthseeker

  Now imagine this situation. I have a computer which has 2 operating systems installed - Windows XP and Windows 7. On booting menu is displayed where I can select which operating system I want to load. When I do nothing, Windows 7 loads (after some delay). This computer is connected to LAN and has Wake-On-Lan function enabled. Is it possible to remotely select which operating system I wish to load? Now it is Windows 7. But sometimes I wish it would be Windows XP.

• Keyboard shortcut / navigation references

  - by jerryjvl

  I use the mouse much too freely, and my wrists are not thanking me for it. I have been meaning to try and use the keyboard more as my sole means of navigating Windows, but I am having trouble sticking with it because when I need to do something and I cannot find the right shortcut, I grab the mouse and forget to let go of it again. Personally, the main software that I need keyboard reference sheets for would be: Firefox Thunderbird Visual Studio Windows itself But I would encourage more general inclusion of shortcut references in the answers in case anyone else tries to make the same transition I am attempting ;) What I am looking for is reference material that is as comprehensive as possible so that over time I can hopefully learn to do everything with the keyboard and spare my wrists. Bonus points for references that can be printed in a reasonable size so I can keep them next to my machine in hardcopy. I know there is an answer for Windows already: Is there a definitive reference for Windows shortcuts keys?, but I am leaving it in my question in case anyone has a better printable alternative.

• Algorithm for grouping friends at the cinema [closed]

  - by Tim Skauge

  I got a brain teaser for you - it's not as simple as it sounds so please read and try to solve the issue. Before you ask if it's homework - it's not! I just wish to see if there's an elegant way of solving this. Here's the issue: X-number of friends want's to go to the cinema and wish to be seated in the best available groups. Best case is that everyone sits together and worst case is that everyone sits alone. Fewer groups are preferred over more groups. Sitting alone is least preferred. Input is the number of people going to the cinema and output should be an array of integer arrays that contains: Ordered combinations (most preferred are first) Number of people in each group Below are some examples of number of people going to the cinema and a list of preferred combinations these people can be seated: 1 person: 1 2 persons: 2, 1+1 3 persons: 3, 2+1, 1+1+1 4 persons: 4, 2+2, 3+1, 2+1+1, 1+1+1+1 5 persons: 5, 3+2, 4+1, 2+2+1, 3+1+1, 2+1+1+1, 1+1+1+1+1 6 persons: 6, 3+3, 4+2, 2+2+2, 5+1, 3+2+1, 2+2+1+1, 2+1+1+1+1, 1+1+1+1+1+1 Example with more than 7 persons explodes in combinations but I think you get the point by now. Question is: What does an algorithm look like that solves this problem? My language by choice is C# so if you could give an answer in C# it would be fantastic!

• Windows 7 strange boot issue

  - by JL

  Recently I installed an SSD drive, its now my primary boot drive (OCZ Vertex Turbo 60GB). I'm running Win 7 (64bit). Now I am not sure exactly where the fault lies, but when I do a restart from within Windows, the computer will boot and enter into the loading windows portion, however won't progress beyond there. My solution is to manually hit the reset switch, and then when it boots it enters into a windows menu that offers a start up repair or start windows normally. I select start windows normally, and then it boots fine. I am not entirely sure why I can't just restart the computer from windows normally though. The SSD drive works perfectly, and not even sure if it is the cause to this problem. Any ideas on this?

• How can I clear the "authentication cache" in Windows 7 to a password protected samba share?

  - by Chris Drumgoole

  I have a Linux samba server and have explicitly listed users that can access the folder. I have successfully congfigured Samba to require a username and password when accessing the share from windows (using the smbpasswd, etc.). But now I want to force clear the auth cache on the windows machine. Such as when I go to a colleague's computer, I use my account to access a file in the protected share, but then before I leave his computer, i'll want to make sure the authorization cache is cleared so he cannot access that folder with my credentials. I found the command to use in the windows command prompt on google a couple of weeks ago but silly me I didn't save it... Hope someone can help, thanks! Oh, Samba is configured as a workgroup and not a domain (if that helps) - so windows users do NOT log into a domain on start up. thanks!

• Ubuntu 12.04 + Bluetooth problems with maintaining connection

  - by ifndefx

  I have an Apple Wireless Mouse, Apple Wireless Keyboard, Apple Wireless Trackpad, and a pair of headphones. All of these connect to the computer via a Bluetooth dongle. After several hours I've managed to get the devices paired (all except the headphones) with the computer. However, I'm facing a problem where a connection can't be maintained even with one device. I first started with the gnome bluetooth applet, this couldn't even pick up devices, so I installed blueman, and this at least detected the devices but it couldn't keep the connection going. Then i read somewhere to get hidd installed and use the command line using the mac address of the device (which I got from blueman) and this worked really well, the connection was stable, but there's still a couple of issues that I need help with: If I am to use hidd I need to execute this via terminal, which means for the keyboard and the mouse I need to have two of each. This doesn't make sense. I need the bluetooth daemon to have started with the devices picked up a lot earlier, and especially at grub bootloader. The mouse and the trackpad both work if i use hidd, however, I cannot get the right mouse to work nor the scroll wheel to work. The headphones don't work period, they don't work with any of the bluetooth applets, and with hidd either. When I use blueman aplet, it attempts to pair and states 'Authentication Rejected". The headphone is Phillips SHB9100. If someone can help me with this, I would be grateful.

• Laptop crashes when connecting to external harddisk

  - by Gnot

  I recently had a problem with my laptop. when I booted up the machine, I would get a SMART failure error message and when I pressed F1 to continue, it would take a very long time to boot and it would come back to the same error message again. Thinking that my hard disk was dying, I bought a new hard disk and installed on my laptop and so now my laptop is alright. However I need to recover data from that old hard disk, so I bought an external hard disk case and placed the old hard disk onto the case and connected to my laptop with USB. The first few times when I connected, I could see the files from the old hard disk and managed to copy some files over although it took extremely long to transfer. But now whenever I connect to the old hard disk, after a few minutes, my laptop will crash and re-boot. Do you think my old hard disk is dead beyond repair? Or you can offer some help here? Any assistance would be appreciated!

• Hostname confusion (Ubuntu Server 10.04)

  - by letseatfood

  I have just setup Ubuntu 10.04 Server Edition. I have been following this tutorial. The DNS information seems to be setup correctly now, but I am confused about the hostname. Currently it is laughingbuddha.home. That is a name I created. Now, I am mainly not sure how to connect from another computer on my network. I basically want to be able to put PHP files on the server box and then test them via a web browser on my other computer. So, I think I digressed from my first question, but would somebody please help me figure out if the hostname is okay for doing what I need to do? Thank-you!

• xl create doesn't bring up console

  - by ineff

  I've tryed to run VM in Xen 4.2 using xl command (for what I get this should be standard toolstack, while xm is deprecated). In this case I've the following configuration file kernel = '/media/home_separata/domU_kernel/boot/vmlinuz-linux' ramdisk = '/media/home_separata/domU_kernel/boot/initramfs-linux.img' name = "domU_Arch_linux" memory = "512" root = '/dev/xvda1 ro' disk = ['file:/media/home_separata/domU_kernel/arch_linux_kernel.img,xvda1,w'] vif = ['mac=aa:::10:11:f1,ip=192.168.0.2,bridge=xenbr0'] when I try to start the virtual machine with xl create it seems it works (it also bring up the vif interfaces) but if I try to connect via xl console it gives an error: xenconsole: Could not read tty from store: No such file or directory the fun fact is that the I've the problem inverse using xend/xm (in that case xend doesn't bring up vif interfaces but activate console). Does anyone have any suggestion?

• how to get wireless to work on my HP Compaq nx6325 Notebook on 12.04

  - by user211487

  When my laptop ran XP, the wireless worked perfectly. Now the only way I get internet is having it wired in my living room - which is MASSIVELY inconvenient for me seeing as my room is outside. I have downloaded the driver from 'Additional Drivers', reset my computer (with difficulty, it also doesn't seem to like turning off, so I have to 'kill' it) and still nothing! I have looked all over the internet trying to find solutions but I just cant seem to get it to work. I have a USB wireless stick but I can't load the driver from the CD. I got this comment on a previous question: "Using either Snaptic Package Manager or Ubuntu's own Software Centre, remove "bcmwl-kernel-source" if it's already installed. Next, search for "firmware-b43-installer” and “b43-fwcutter” and install both. Finally, running Software Sources and checking the Additional Drivers tab you should find Broadcom STA Wireless Driver that you can select, install and on reboot hopefully have wireless working ok..." Which I replied: "Right, so I tried to find/remove "bcmwl-kernel-source" but couldn't find anything. I managed to install both "firmware-b43-installer” and “b43-fwcutter” using terminal, after finding out how it worked. And lastly, I couldn't figure out how to find 'Broadcom STA Wireless Driver' - still no more additional drivers. And my wireless is still not working. My laptop has a button that turns wifi on and off and since I put Ubuntu on it, it hasn't worked. And also, my computer still doesn't seem to restart properly - it just gets stuck on the ubuntu loading screen." - hope that helps, somewhat I am VERY new to Linux, not very technical and in need of help! -Running Ubuntu 12.04 32bit on a HP Compaq nx6325 Notebook Thank you to anyone who replies, its much appreciated

• How can I have sound output before logging in?

  - by ??O?????

  I have a machine (Ubuntu 11.10) that I would like to have it play audio (typically through an amplifier), but the machine should be headless (where its final placement will be). I will control what is played through ssh. However, there is no sound output until I login to the graphical console. At first I thought it was an issue with pulseaudio, so I promptly removed it to use the default ALSA, but I have the same issues. I ssh to the machine, I run alsamixer and get the typical cannot open mixer: No such file or directory error (while /proc/asound/cards display correctly what I have). If I login on the graphical console, alsamixer works fine in the ssh session, and I have sound output. I logout, and then alsamixer stops working. So something runs (Xsession perhaps?) when I login that enables sound output, and gets disabled when I logout. I remember in older versions of Ubuntu, there was a drum roll when the machine showed the login screen; that is not the case anymore. Perhaps if I somehow can enable that drum roll, I'll have fixed my problem too. In any case, the question I ask is what the title says.

• Extremely poor WiFi reception on new desktop

  - by guy

  I just received a new desktop with a built-in WiFi card (Windows 7 Home Premium x64). However, I am only able to receive any WiFi signal when the computer is within 1-2 meters of a router. Even then, the signal is very weak (Windows 7 says it is "poor"). I have tried this with 2 different routers and see similar results. I have somewhere around a dozen other devices that can connect to both routers with greater signal strength (usually full strength) from much, much further away. When I tried calling support I was instructed to reinstall my drivers and attempt to change the WiFi channel of the router. Neither worked. I was then told that the problem was with my routers and that the computer was functioning normally and that it was certainly not a hardware problem. What would be the cause of this and is there anything I can do to fix it?

• Downclock CPU reaching critical temperature

  - by Draga

  I have an HP tx1250 laptop. It always had serious overheating problems and although usually it runs fine I'm now running a continuous test for my dissertation, this brings the CPU temp close to the critical and from time to time the computer shutdown for reaching it (checked the log). I use to have the same problem on Win XP but I noticed Win Vista and 7 downclock the CPU when is necessary to cool it down so I was thinking if the same is possible on Ubuntu 12. The only program I've found that may do the job is computer temp ( http://computertemp.berlios.de/ ) but it doesn't seems to work under Ubuntu 12. The inside of the laptop is fairly clean, the thermal paste is quite recent, I'm keeping it lifted from the desk and judjung by the sound of the fan that's running fine as well. The pc in now running between 78 and 91 degrees C but about once a day it shut down for reaching 95. I need the results of the test it's running pretty soon so it's important that it runs non-stop. I've though to set the maximum clock of the CPU to slightly less the maximum but then these tests I'm running would take much more time. Thanks! PS: first and last HP laptop for me.

• Force shutdown a pc stuck in updating via Team Viewer

  - by Martheen Cahya Paulo

  Before I left office, I shutdown my work computer, leaving it in "Please do not power off..." screen. Now, when I log on to my own computer, I saw in Team Viewer that it's on. I thought it restarted instead of shutting down, but when I connect to it, it's still stuck in the previous screen. I've tried sending Ctrl-Alt-Del, but it seems to ignore it. I could still change its resolution via Team Viewer, and the fact that it respond my connection means it's not completely stalled. Is there anyway to shutdown it via Team Viewer?
