• Poor CPU usage under Ubuntu

  - by remek

  Hello, I just upgraded from Ubuntu 9.10 to Ubuntu 10.04 and I am now experiencing a strange problem. My computer has a quad-core processor, and when I am running several processes simultaneously, none of the cores is fully used. Before the upgrade, when I was running 4 processes, each of them was using 100% CPU (I could see that with the 'top' command). But now, CPU usage oscillates and is always pretty low. Has anybody an idea about this problem? Is it due to Ubuntu or to the program I am running? Thank you very much in advance for your help! Best, remek

• How to show what proxies/firewalls are enabled on Windows XP?

  - by Stephen Melrose

  Hi, I'm trying to fix a Windows XP PC that is having a strange problem. The computer can't seem to connect to the internet, even though an internet connection is present. The router and internet is working fine as I've connected a laptop to it via LAN and wireless and both worked fine. The PC in question is connected to the router as it has an IP from the DHCP. The problem is I can't connect to nor ping any internet address from the PC. I can't even connect to the router admin itself. I've tried both LAN ports in the PC, same problem and both. I'm assuming there's a proxy or firewall on the PC stopping the connections, I just don't know how to find them or see which one is causing the issue. So my question is how do I on Windows XP display the system proxy settings and/or any firewalls that are running? Cheers.

• Suggestion of device WiFi range in it's spec. Possible?

  - by SeeR

  I have router Draytek Vigor 2100VG at home almost in the center of it. The farthest point at my home is my balcony, ~12m from it. I have constant wifi signal range problems with some of my devices, but not with others. Notebook Lenovo W510 - no problems Nokia Home Music - always on 10m - no problems Sony PS3 - always on 7m - no problems Sony tablet S - problems around 6m Sony PSP - problems around 8m Sony PS Vita - problems around 8m Nokia E63 - problems around 8m I'm curious why my Notebook don't have any problems even on the balcony? I guess it has better hardware or uses more power for transmission. This information is really important when you want to buy new device/computer, so my real question is: Can device wifi range can somehow be found/suggested from official hardware technical specification? If not Is there some web page with wifi range reviews?

• Blackberry Won't Sync: Says Processing

  - by Noah

  I have a blackberry storm 2 and I have it set up to sync, just like I've done with all the other ones in the company. They pull the address book/contacts from outlook, and aren't synced to an exchange server. I have everything setup and then when I hit synchronize it flashes "processing" the phone shows it trying to sync and then it is done in less than a second. It did warn me that the computer was not supplying enough power to charge the device and it said that I should make sure the drivers are correct. Also, I was warned that the device might not function properly down in the bottom right hand corner. Any ideas? I've uninstalled and reinstalled the blackberry software off the disc.

• How can I make VNC faster?

  - by NickAldwin

  I need to remotely access and use my work computer a few times a week. I want to use VNC because of the price. I've used VNC before, mostly on my own network, where it's fast. However, VNC over the internet is incredibly slow. Even at 256 colors and lower, with Aero turned off, it is unbearably slow. I recently used Ammyy Admin to connect to do something requiring a quick reaction time. Ammyy was really fast, with almost no lag, and it was running in full color with Aero on! How can I make VNC faster, like Ammyy is? I'd use Ammyy, but I would probably run into the 15hr/month limit pretty quickly. Any suggestions? [EDIT] I'm currently using UltraVNC.

• Prevent Chrome from automatically opening downloaded PDF and Image files

  - by Phoenix

  When I download a PDF or image in Google Chrome on my Mac, is it possible to prevent Chrome from automatically opening it in my default application for that file type (e.g., Preview)? I notice that Chrome does not do this for other downloaded files such as audio and ZIP archives. I still want to be able to preview files in Chrome; I just want to prevent it from automatically launching my image/PDF viewer application after I download them. For example: I click on a link in an email to a PDF document or an image file. Chrome displays the contents in the browser. I press Cmd-S and save the file to my computer. When the download finishes, the file opens automatically in Preview.app. It's that last step that I would like to bypass.

• What is the cleanest way to upgrade Fedora and also my individual installs while keeping /home?

  - by Don

  I am a professional programmer, using Fedora 10 (and a host of other packages individually installed). I use my system to telecommute. Every year or so, I go through the ritual dance, usually with a second computer and a KVM switch as I don't have office space for two monitors, to build the next version of Fedora and install all my favorite apps. Is there a better way? At least a nice way to keep track of what I need to 'add on' so that I don't have to manually install my app collection? Also, I keep /home on a separate raid-ed drive set so I can also fall prey to 'old-config-file-itis'.

• Samsung TV connected to PC for Powerpoint

  - by Skaughty

  I have a 42" Samsung LCD TV connected to a Dell computer with a PCI Radion 9000 via a 35' VGA cable. It's purpose is to run power point presentations over the TV for our retail store. I have tried every combination of button clicking on the video card options, and everything on the TV, and I still get black bars on the top and bottom of the image. It looks like I am watching a old wide screen movie on a full screen TV. The TV's suggested resolution is 1024x768, and that is what the output is set to. I have tried this with a nVida PCI card as well with the same results.

• Installing Chrome OS on HP Pavilion

  - by Lenny K

  Trying to install Chrome OS on HP Pavillion tx1000. I changed the BIOS to boot from USB before hard drive, and created a bootable USB drive (SanDisk Cruzer 4GB). No matter how many ways I try to make the USB drive, the laptop hangs on the startup screen, and trying to open the Boot Order Options freezes on "Fixed disk 0: ...". On the other hand, without the USB plugged in, the computer continues, and displays "Initialized Mouse", and then onto the Boot Order Options. If you let it boot normally from the beginning, it starts up fine into Windows Vista. I am using Hexxeh's Chrome OS build. Here are the different methods I've tried for making the Bootable USB Drive: Hexxeh's Image Creator (for Mac) Making the USB device bootable (using these directions). I wrote the image using Win32DiskImager. Writing the image using Win32DiskImager (without making it bootable).

• Cannot connect to internet with Clearwire modem.

  - by ide

  I'm currently using a Motorola WiMAX modem (CPEi 25725) and cannot connect to the internet. I can connect to the modem at 192.168.15.1 and check its status. It says that it has good/excellent connectivity to the internet and shows all five signal bars. Additionally it has sent and received some WiMAX packets so I believe it is connected to a tower. I'm at a loss for what the problem is. Unplugging the modem, restarting it from software, and restarting my computer (Windows 7) have not helped. Windows still reports that it is not connected to the internet. Alternatively, could this be an ISP issue? I have heard that Clearwire is a not-so-reputable ISP that blocks VoIP, and I was using Skype recently.

• How to cd into smb://[email protected] from terminal?

  - by John

  I am using ubuntu and gnome on my computer. When I open up File Browser, on the left hand rail, I see conveniently a folder called "Work Server". When I mouse over it, the following caption appears "smb://[email protected]". If I click on that folder, then I can see the contents of that folder. Everything is great. So now when I open up a terminal/shell, I type in cd smb://[email protected] I get an error saying the directory doesn't exist. How do I enter this directory via shell/terminal?

• Extend university wifi network

  - by asfasdoiuh ouhouhouh

  i live in a university campus and i can get wifi signal on the outside of my window but not in the house. The solution i use at the moment is a usb wifi dongle outside connected to my laptop but the lack of an internal antenna make the connection quite unreliable at times. So i was trying to find another solution to improve the reception of my network. One idea is to setup a router on the outside (in a place with stronger signal) and redirect the connection inside the house with an ethernet cable but the problem is that our Uni Wifi is managed by a capitve portal (BlueSocket with DNS redirection to login page) and the authentication has to happen on the mac address that connect to the net (so the client appliance in this case). If I use a router with Mac-Clone capability i will be able to be redirected trough the captive portal on my laptop computer and login from there or i need to setup my router to fill in the login page by itself? There are other hardware/software solutions i can use to get what i want?

• Reasons for Wi-Fi to be slower on Ubuntu compared to Windows?

  - by den-javamaniac

  I'm using 64-bit Ubuntu 12.04 and Windows 7 64 bit – dual boot on the same computer. Connecting to the same wireless network. And it turns out that on Windows I get a more stable and stronger signal than on Ubuntu. To my knowledge there's a router which serves as a gateway and then there's a cable connected to the router which goes further to ISP, so the results for both OS should be the same. I've tested the issue on both OSs at various times and it gave me the same result. The question is why? Why Ubuntu networking is worse than that of Windows?

• Failover NIC with Windows 7 running Apache Server

  - by Benjamin Jones

  I have a Apache Server running on a Windows 7 Desktop for a internal website (Intranet). I am trying to figure out how I can make this system as failover safe as possible. One thing I want to do is use the 2nd NIC card that is currently disable. I only have one gateway address to my router. I do not have any computer running a Server O/S. If NIC1 crashes by chance(just humor me!), how could NIC2's IP take on the host name (I have mapped in host file) . I don't really care if the static IP of NIC2 changes seeing that the host name is the only thing I need. Could I add two IP's to the host file, with same host email and maybe create some script that will run IF NIC 1 fails? OR is there any failover software that will do this for me?

• sata2 hdd not reported correctly on gigabyte mobo

  - by hyperboreean

  hey guys, I have a gigabyte ga-k8nmf-9 mobo which has both sata 1 and sata 2 support. Until a few hours ago I had a samsung 160gb sata 1 hdd which worked ok until it failed. I bought a wd se16 caviar, 500 gb, 7200 rpm, 16 mb cache, but it seems that it's not properly detected by my computer - it's only showing 137 GB out of 500. I tried a BIOS update (to F10e) and it's still doing the same thing. I've altered BIOS settings to use only sata (no ide) and many other settings, but nothing worked. Any help will be greatly appreciated Update on this one: it seems that the previous hdd was doing the same thing, though I didn't notice because it was approximately the same size

• Mouse Hang with voltage fluctuation

  - by user265495

  I bought a new assembled PC about a month ago, but for the past 7 or 8 days I found my mouse cursor hangs every time there is a voltage fluctuation on my UPS (I guess it as when sound comes from ups then mouse hang for 2 or 3 sec. and them it goes normal again). My PC also seems to shut down while I'm working and it refuses to boot again - I end up needing to switch off my UPS and press and hold the power button for 30 seconds. It will then boot as per normal. Could the trouble be with my PSU? Am I potentially damaging my computer by pressing and holding the power button? I have : Motheboard : intel Chipset Model - DH61WWAAG23116-303 Processor : Intel Core i3 3.20 Ghz RAM : Zion 4 gb DDR3 HDD : 1 tb GRAPHICS : 2 gb NVIDIA GeForce GT-610 CABINET : Frontech Rock OS : Win 7 32 Bit

• Start Menu freezes when highlighting 'All Programs'

  - by gergesi

  Hey all, A friends machine is lagging for about 30 seconds when they highlight 'All Programs'. A gray box popus up where the program menu would be, but it doesnt populate for nearly 30 seconds. This seems to happen if he hasn't open the start menu for a bit.. but if he get's it working once, doing it immediatly afterwards will usually not have the same lag. Assuming computer hardware isn't an issue, any ideas what the problem may be? Sidenote: He mentioned making desktop shortcuts is taking long as well, does that give any clues?

• Outlook 2010 : "An error occurred when setting schedule permissions"

  - by francisswest

  Computer: Windows 7 x64 Enterprise. Office 2010 with Outlook 2010. Exchange account and a couple of IMAP accounts connected to the Outlook profile. Error: When attempting to share the calendar with anyone (selected from the address book) by click on "Calendar Permissions" seen here You can add or remove people without issue, except that no matter what, even if nothing is done, just opening the sharing window and closing it, you get an error message that says "An error occurred when setting schedule permissions" Verified that the issue doesnt actually effect the sharing, or the general setting of permissions. The error however is disconcerting to my user, and I would like to alleviate the problem if possible. Thanks!

• Long wait until POST...

  - by Wesley

  Here are the specs to put things into context: ECS P4VXASD2+ (V5.0) motherboard Intel Pentium 4 Northwood 2.8 GHz (512 KB L2, 533 MHz FSB) 2x 512 MB PC2100 DDR266 RAM 128 MB NVIDIA GeForce FX 5200 AGP WD Caviar SE 80 GB IDE HDD Gigabyte CD-RW drive OKIA 300W ATX PSU So, everytime I try to boot up this computer, it takes at least 10-15 seconds before it will POST. All my other machines will post within 1-2 seconds, but this one takes a particularly long time. I've read suggestions from a Google search to swap the CMOS battery, check BIOS settings, and double check CMOS jumper. Still after follow those, it takes a while to POST. What else could be causing a long delay before POSTing?

• How can I use my laptop's monitor as my PC's ONLY monitor? (please vote to reopen) [closed]

  - by Randell

  Please vote to reopen. This is different from Can I use my laptop as a second monitor for my desk computer?, because that question is asking how to use the laptop screen as the secondary display, not as the only display. My PC's monitor just died and I'm not looking at buying a new monitor anytime soon. So I'm thinking of using my laptop's monitor for it. Both machines are running on Fedora linux. Edit: Both machines are connected to the same wireless network. PC needs to log in before it can connect to the network if I'm not mistaken.

• Win 8 start screen resolution

  - by Abhijith

  My screen resolution is 1280x1024 running Win 8 RP I formatted my computer and reinstalled Win 8 CP because I had too many BSODs. When I installed Win 8 CP and created a local account. I had 5(or 6) tiles per column. But once I switched to the Microsoft account to get my synced wallpaper and lock-screen, the Start screen resolution changed and I got a max 3 tiles per column. The size of all metro apps including the Settings app changed and became awkwardly bigger. Is there a way to get back 5 tiles per column? Essentially changing the resolution of the start screen?

• Multiple workstation setups using virtualization - best solution

  - by Vazgen

  I'm looking to set up a server for my small startup. I have a few employees and would like to use my computer at home to provide them all with workstations. Each workstation should have the same collection of software installed but each user's workstation should be completely separate from the others. I need each user to be able to remotely log in to their workstation (using TeamViewer or something like it) and I want to be able to monitor their workflow from my screen. I suppose I need a virtualization solution. Can anybody recommend one with easy set up, I'm not a server administrator.

• HFS partition mounting read-only

  - by Sid

  Hey, I have an external Western Digital Hard drive with two HFS partitions with journaling disabled. When I connect it to a computer running Linux (Debian or Ubuntu), frequently both partitions are mounted read-only. In the past, mounting them on my Macbook and executing the command to disable the journaling often worked (even though it would tell me that journaling was already disabled) but I would love to have a solution which works every time. Thanks! Edit: In light of Chris Johnsen's comment below - my question is how to mount the filesystem read+write on Linux since it is not automatically doing so itself

• Apple Wireless (aluminium) Keyboard on Windows

  - by Dave Arkell

  I have an apple wireless keyboard which I am using with my windows pc and it works excellently, and looks superb. It all connects fine (particularly with a flashed dbt-120). However, I haven't had great success with getting all those useful keys to work with the 'fn' key. I've been using uawks as a way to get it working, but it doesn't always work. Has anyone had success with any other tools to get the fn key working (and therefore creating shortcuts to 'End', 'Home', 'Break', 'Pgup', etc? I should point out that this is not a mac computer, it is a plain old pc.
