• FlasCC requirements and limitations?

  - by Arthur Wulf White

  It is now available for download. It says you need twice* as many bits as I have. Why would you need more bits to compile code? Does that mean you need more bits to run flash games writtes with flasCC Did anyone try it out and happens to know the answers? http://gaming.adobe.com/technologies/flascc/ Minimum system requirements Flash Player 11 or higher Flex SDK 4.6 or higher Java Virtual Machine (64-bit) Windows Microsoft® Windows® 7 (64-bit edition) Cygwin (included) *This is meant as a joke. however I do own a 32-bit laptop and I am wondering why you need 64-bit. Afaik - You only need 64-bit if you want to run a system that has more than 4gigs of memory. Why would any flash game require more than 4 gigs of memory. The only system that is 64-bits and does not have 4gigs of memory that I can quickly recall is that hilarious Nintendo that came ages ago with a Motorola CPU.

• Recovering an Ubuntu installation - Ubuntu eats itself after 'sudo apt-get install -f'

  - by Tony Martin

  Updater (I assume) put a no entry style alert icon on the panel which informed me that certain package dependencies were not up to snuff. Upgrades were thereafter only partial. The dialogue advised that I sudo apt-get install -f. I did this hoping that app-get would fulfil dependencies and replace corrupted files and watched it systematically remove every component of linux, both the stuff I had installed and the core ubuntu packages. I could only assume at this stage that this was in preparation for a fresh install but, of course, I know better now - if you find yourself with apt-get warning you that you are about to remove several hundred packages and asking you to type an involved confirmation string seek advice before proceeding. I digress. This was a 64 bit install of 12.04. All that is left is grub pointing to a couple of windows recovery partitions on the hard drive. Thankfully the Ext4 partition is reachable from a stick boot. EDIT: I've logged onto the machine with a 64 bit stick and can see the file structure left behind by apt-get after {ahem} fixing. My first instinct was to run install from the stick but it seemed to want to do another install rather than a repair. My question then: is there a way to recover the current installation so that if I reinstall the packages I had they will pick up the original settings? I'm particularly worried about losing email from evolution - the rest I could probably lash back together. As for the use of PPA I'm not sure what you're driving at. I generally use Ubuntu Software Centre to install software, though I have used terminal scripts to add new repositories and software successfully following guidance on various websites. The most recent change I made was a downgrade of Wine in an attempt to install and run excel2007 (a necessity, I think, as I have VBA work to do). The installer had stalled and had to be killed. I wonder if that corrupted whatever database holds a model of the package installation structure. I would also be interested to know how this disaster came about. I see people in the know recommending the sudo apt-get install -f as a fairly innocuous cure in similar circumstances. Thanks for your attention, Tony Martin p.s. Do please forgive the rant aspects of the original post. It's hard to write rationally with a large hole in the pit of your stomach.

• combo microphone does not work on Natty.

  - by Senthil Kumaran

  I have a Internal Audio Hardware card and my Laptop (Lenevo IdeaPad) presents a single slot as a combo Microphone and headphone jack. On Windows, I attach my ipod headphone to jack and speak directly to my computer. I assume there is a microphone which is listening to my voice and I can communicate two-way. On Ubuntu, the microphone always seem to be listening to random noise. So any input by speaking to the computer is not possible. What could be the reason and how do I troubleshoot this?

• Can't connect to WIFI after sleep Ubuntu 14.04

• Maximized Office 2007 gets cut off on multi-monitor setup with different resolutions

  - by Adam M-W

  I've got an external monitor plugged into my laptop that I like to use for typing up documents, but I've noticed that when Word is maximized it gets cut off at where the primary monitor's bounds are. Is this a bug in Wine (i'm using version 1.3.32), or with my Window Manager (metacity with compositing enabled, version 2.34.1), with my graphics drivers (nouveau) or something else? I know that I can fix it by unmaximizing (it doesn't get cut off and I can resize to the entirety of the second monitor), but it keeps on maximizing itself as it (rightly so) knows that it should be taking up the entire screen. I don't really want to use the "Emulate a virtual desktop feature", I would prefer to find the source of this issue.

• Can't Enter Password in Recovery Mode

  - by Mike Lentini

  When I go into recovery mode to get to the command line, I enter "telinit 3" to drop out of root. This works on my desktop, but on my laptop it asks for my username and password, then I hit enter and the first letter of my password appears and it doesn't log me in. It then proceeds to ask me for my username and password again, and the issue continues. Am I doing something wrong? Is this a known issue with a solution? EDIT: Worked around this by going into /etc/default/grub and setting it to boot in text mode. Still would like a solution for this though.

• Installing windows after ubuntu is installed (need to create ntfs partition too)

  - by Brent Roose

  I prefer Ubuntu to work on, but for some applications for school, I need windows. I've done some research and have a few problems: I only have one hard drive which is formatted as ext4, not ntfs. Many people say I have to use Gparted to create an ntfs partition to install windows on, the only problem is that I need to unmount my drive to do this, which isn't possible I think because I only have one. I thought about mounting my HDD as a slave on a windows laptop but I don't manage to partition it with windows partition manager, so I think I need some kind of tool. which one? next problem I'll probably have is that I won't be able to boot ubuntu after installing windows because grub will be removed from my MBR. are there any good guides around here? I've used some kind of tool before, but it crashed my whole HDD so I had to fully format it.

• Keyboard freezes when xorg crashes.

  - by gsedej

  Situation is like that. Many times has happened that Xorg freezes and with it also keyboard. Quite some times because of some Compiz effects or Flash (fullscreen switch). Keyboard becomes totaly unresponsive, while mouse still works (I can move cursor, but can't click since desktop freezes) and music still plays and I can connect trough ssh. This is the only way I know I can try to solve problem - either by killing browser&flash or lastly restarting xorg server. This problem appears on more than one Ubuntu computer. My home dekstop with proprietery nvidia driver, on my work where I use noveau driever (opensource driver for geforce) and sometimes (but rarely) also on laptop with ATI graphics (using r300g driver which is really good!). Can someone explains why mouse still works while I can't input from keyboard? (I can't switch to virtual console or do R-E-I-S-U-B command) I have USB keyboard and USB mouse.

• What to do?! Upgrading from 12.10 to 13.04 failed :(

  - by Jon Ramirez

  I got an update reminder to go from 12.10 to 13.04. I followed the instructions, was able to download the package, and started installing. Up to a point where my computer (seemed to) restart and there was just a black screen (with the backlight on) for more than an hour. Then I decided that this was too long for an installation and forced my laptop to shut down. I think that messed it up. Now I'm stuck in what seems to be 13.04 with bits of 12.10 in it. I tried to upgrade again through software updater but it goes to Partial Upgrade. But when I try that, I get this error message: "An upgrade from 'raring' to 'quantal' is not supported by this tool." Help! What should I do! I'm running my Ubuntu on my Dell Inspiron.

• why would Remmina stop working?

  - by Chris Curvey

  Until sometime last night, I had remmina working fine. I could run RDP through an SSH tunnel and all was well. Then it stopped working. I can get as far as the password dialog for my work machine, but then it just says "Cannot connect to RDP server localhost". I can't even find any logs that look interesting. I've re-installed remmina, cleared my .remmina directory, restarted my machine, and even restarted my gateway. Just to make it really weird, my laptop (which has the same setup -- latest Ubuntu and Remmina) can make the connection just fine. It is even going through the same router, albeit wirelessly. Any thoughts?

• Ubuntu - Black Screen After Suspend

  - by EssAm

  I used Ubuntu with no problems and I upgraded to 11.10 and everything was fine. But when I did my first suspend I was not able to boot again, all I got was a black screen no bios screen, nothing just blank, I tried doing hard reset but when I power on again same happens. I tried ctrl+alt+delete F1-F12 but i think the keyboard is not working, also tried booting from CD but all I got was blank screen, the hard disk light is not blinking at all so i'm assuming it's not trying to boot. My laptop is Toshiba satellite with ATI Radeon graphics. Hibernate was working fine though. I searched the net for solutions but with no luck. Any ideas?

  - by Hitesh Bhatt

  I have a Sony laptop (VPCEH25EN) and i am trying to install Ubuntu 12.04 LTS. I downloaded the iso named "ubuntu-12.04-desktop-amd64.iso". For installing i created a bootable USB using UltraISO. When i booted the USB it hangs and shows " Booting from USB ", I even left it for hours and it didn't moved a bit. When I booted the ISO in Virtual Box, it ran well. I even used other tools to make a bootable USB, then it says " BOOTMNGR missing ". Please help, I am new to Ubuntu and my optical drive is fried. Thanks in advance..

  My Laptop is Acer 5742G with "Npilfy 802.11 wireless". I have both windows 7 and Ubuntu 12.10 Earlier when I had Ubuntu 12.04, the wireless was working fine, but after installing 12.10 wireless is not working at all, although it is still working in windows. I am not able to see "Wireless Networks" in the Network Manager nor in the Network Settings. This was the output I got for rfkill 0: acer-wireless: Wireless LAN Soft blocked: no Hard blocked: no 1: acer-bluetooth: Bluetooth Soft blocked: no Hard blocked: no 2: hci0: Bluetooth Soft blocked: no Hard blocked: no This is a snapshot of my Additional Drivers settings.

• Live CD boot/installation problem, blank screen - 12.04

  - by traubi

  I'm trying to install ubuntu-12.04-desktop-amd64 from my usb stick. When booting from usb I instantly get a blank screen (with a grey box at the left bottom) I checked the live system with my laptop.works well except it also starts of with a black screen and a grey box at the bottom. I figure the Problem is my geforce gtx 570 since older versions of Ubuntu where only able to boot with xforcevesa and nomodeset. Unfortunately I can't change the boot parameters. I tried the alternate version for a text based install, but it has the same problem. If I press Esc in the alternate I get a message box with two buttons but no text. I would be happy for any advice on this matter

• Video capture Performance

  - by volting

  I have noticed high CPU utilization in a number of applications (except mplayer) which read from the embedded webcam on my laptop. Bizarrely CPU utilization varies proportionately to the level of illumination present. I know that that high CPU usage has nothing to do with rendering the video, as I have written a simple app using the OpenCV library to simply grab frames from the webcam, and cpu usage is still high. I think that mplayer might be using my GPU (and the other apps aren't), but since its not an issue with rendering, I dont think this explains anything. Cheese Low light --- ~12% CPU Bright Light ---- ~63% CPU Camorama Low light --- ~7% CPU Bright Light ---- ~30% CPU Opencv C++ library, (display in a single highgui window) Low light --- ~13% CPU Bright Light ---- ~40% CPU (same test on windows 7, 4-9%) Mplayer No problem, 1-2% regardless of light levels Note: If all I want't to do is capture a feed from my webcam I would use mplayer and forget about it, but I'm developing an application which uses the OpenCV to capture a video feed among other things, performance is important.

• Investing in Servers by Intel

  - by Koushal Deshpande

  Originally posted on: http://geekswithblogs.net/BizTalkAndOtherTechs/archive/2013/10/31/investing-in-servers-by-intel.aspxA nice article reference from Intel, refer here. Referees to cloud as well. Choose correctly what you need. 1 Do determine right server for your company. There is no use getting a server that has redundant services but still add to the costs. 2 Do get servers that can be upgraded. A server with limited memory and storage may not be able to keep up with your business growth. The basic memory and storage options might not be sufficient. Consider at least 8GB of RAM and 1 terabyte of hard disk space. 3 Do check the server has at least one Gigabit Ethernet port. This allows high speed transferring of files and increases productivity for your employees. USB and Firewire ports may not be enough as their transfer speed is too low and will affect the productivity of your company. Infinite Technologies is ready to help perform this upgrade. Contact Infinite Technologies now View our other resellers » 4 Do verify that the server comes with documentation. Documentation allows you to make a claim when your server breaks down and is supported by a warranty. 6 Do check the support options for the server from the manufacturer. Different manufacturer has different support options such as maintenance plans and software upgrades. 5 Do always look into the warranty. Get an enhanced warranty that guarantees response and repair time to avoid disruption. 7 Do get server management tools that can be used on any computer. Server management tools should be cross compatible across different operating systems to take into account future PC replacements. 8 Do check the power usage of the servers. Get the right power supply to avoid damaging server hardware and consider the Intel® Xeon® E3 processor to help save on your electricity bills. 9 Do check what built-in security packages are available. Ensure that your server is protected. Built-in security1 helps you save on getting add on security packages.

• Problems after installing Ubuntu 11.10

  - by Andrew Orr

  I'm having trouble with Ubuntu 11.10. It has to do with nomodeset. After I boot into Ubuntu, it goes to a purple screen for about 10 seconds and then goes blank. After that nothing happens. I've read other people's questions about this and I know it has to do with enabling nomodeset. This worked for me when I was using the LiveCD mode, but now Ubuntu is permanently installed as a dual-boot system. Going into recovery mode doesn't work, pressing "e" in the boot loader and writing nomodeset after quiet splash doesn't work either. Holding shift any time it's booting doesn't work. I don't know what to do anymore. I have an HP Pavilion dv6 laptop with an AMD A6-3400M CPU, and my GPU is an AMD Radeon HD 6520G. I've never worked with Linux before so taking me through this step-by-step would be great. Thanks!

• Build a LEGO Creation without Leaving Your Cube

  - by Jason Fitzpatrick

  Just because you’re stuck at your desk doesn’t mean you can’t sneak in a little fun. At BuildWithChrome you can slap together virtual LEGO bricks with ease. The site, a collaboration between Google and LEGO, shows you a massive map of Australia and New Zealand covered in thousands of LEGO base plates. Zoom in, select a base plate, and get building. The block selection is fairly limited (you can work with the kind of blocks you’d find in a generic LEGO brick pack) but it’s still quite a bit of fun. When I took it for a test drive, I started simple by building a house-like structure: With the addition of a few more pieces it would be possible to pull off the wizard shop my wife and daughter just built: How to Banish Duplicate Photos with VisiPic How to Make Your Laptop Choose a Wired Connection Instead of Wireless HTG Explains: What Is Two-Factor Authentication and Should I Be Using It?
