• Broadcom BCM4313 takes ages to connect

  - by Drazgo

  I'm having issues with my broadcom BCM4313 wireless adapter. Everything works just fine when connected (with additional drivers & Connman), but it takes about 5 minutes to connect to my network when i just started my computer! When resuming from hibernation it goes very quick though, so just when I boot my pc it's taking forever... This is what I found in the dmesg output: [ 16.778057] eth1: Broadcom BCM4727 802.11 Hybrid Wireless Controller 5.60.48.36 [ 16.808768] type=1400 audit(1295859939.727:2): apparmor="STATUS" operation="profile_load" name="/sbin/dhclient3" pid=833 comm="apparmor_parser" [ 16.808815] type=1400 audit(1295859939.727:3): apparmor="STATUS" operation="profile_replace" name="/sbin/dhclient3" pid=799 comm="apparmor_parser" [ 16.808825] type=1400 audit(1295859939.727:4): apparmor="STATUS" operation="profile_replace" name="/sbin/dhclient3" pid=826 comm="apparmor_parser" [ 16.809367] type=1400 audit(1295859939.727:5): apparmor="STATUS" operation="profile_load" name="/usr/lib/NetworkManager/nm-dhcp-client.action" pid=833 comm="apparmor_parser" [ 16.809415] type=1400 audit(1295859939.727:6): apparmor="STATUS" operation="profile_replace" name="/usr/lib/NetworkManager/nm-dhcp-client.action" pid=799 comm="apparmor_parser" [ 16.809435] type=1400 audit(1295859939.727:7): apparmor="STATUS" operation="profile_replace" name="/usr/lib/NetworkManager/nm-dhcp-client.action" pid=826 comm="apparmor_parser" [ 16.809705] type=1400 audit(1295859939.727:8): apparmor="STATUS" operation="profile_load" name="/usr/lib/connman/scripts/dhclient-script" pid=833 comm="apparmor_parser" [ 16.809755] type=1400 audit(1295859939.727:9): apparmor="STATUS" operation="profile_replace" name="/usr/lib/connman/scripts/dhclient-script" pid=799 comm="apparmor_parser" [ 16.809769] type=1400 audit(1295859939.727:10): apparmor="STATUS" operation="profile_replace" name="/usr/lib/connman/scripts/dhclient-script" pid=826 comm="apparmor_parser" [ 16.844083] alloc irq_desc for 22 on node -1 [ 16.844087] alloc kstat_irqs on node -1 Any ideas how come?

• Why doesn't my laptop battery charge while the laptop is in use?

  - by larryb82

  Up until a week ago, my laptop has always been able to charge the battery while I'm using it. Now, it will not charge unless the computer is sleeping, hibernating, or turned off. The icon in the start tray states that the battery is charging but it is not animated (it used to be) and of course the power level does not increase. Otherwise, the battery seems to be fine. The battery life is decent (2h+) and while the laptop is in use and plugged in the battery will maintain a constant charge. Any troubleshooting help would be great (i.e. is this a charger issue, battery issues, software issue, etc...)

• I just recursively chmod'd everything under / to 750. Any tips?

  - by Ouairz

  I won't be the first and I won't be the last, I suppose. While playing around with the find command, I made a whoops and it would appear that instead of changing the permissions of the ~/web directory to 750, it changed the permissions of the entire filesystem (/) to 750, however I'm not certain, but any attempt to investigate is thwarted by Permission denied messages. For everything. This was the offending command: sudo find ~/web . type d -exec chmod 750 {} If I'm not mistaken, the Ubuntu team disabled root logins as a safety precaution so I'm out of ideas. I'm (obviously) a total newbie when it comes to file permissions so I was wondering if anyone had some good or even some bad advice to share. I've mentally prepped myself to losing everything on the computer which is only of mild consequence, since I have backups, but I did do a bit of work on this box over the week and it would be a shame to lose it all due to a boneheaded mistake. If you are reading this message, ask yourself, have you backed up any of your work recently? Thanks in advance for any insights. Feel free to scold me for using sudo carelessly

• Why does the task pictogram flashes instead of opening the program?

  - by fredley

  Sometimes, when I select a click a program on the Windows 7 taskbar it won't appear (it doesn't gain focus and remains behind other open windows), and the icon will flash and turn orange. This happens reasonably frequently, and I've had it happen on two separate Windows installs on different machines. It just happened now and the only programs I have with active windows are Chrome, WMP and Explorer (2). It happened when I clicked Explorer. Once this has happened to one window, it affects all windows, and the only way I can switch between programs is by finding the window manually or using Windows+Tab. The only way I've come across to get the computer to snap out of this annoying behaviour is to restart the machine. Is there a way of stopping it? Edit Here's a video of it happening: http://www.youtube.com/watch?v=P12OxKK0kM4

• Laptop runs HOT after 12.10 upgrade!

  - by dinkelk

  I was running 12.04 for 6 months, my laptop ran almost silently and cool enough to hold on my lap. I updated to 12.10 and now my computer gets too hot to hold on my lap and the fan is constantly running on full blast. This is the output of sensors: acpitz-virtual-0 Adapter: Virtual device temp1: +84.0°C (crit = +99.0°C) coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +84.0°C (high = +86.0°C, crit = +100.0°C) Core 0: +74.0°C (high = +86.0°C, crit = +100.0°C) Core 1: +72.0°C (high = +86.0°C, crit = +100.0°C) Core 2: +75.0°C (high = +86.0°C, crit = +100.0°C) Core 3: +84.0°C (high = +86.0°C, crit = +100.0°C) radeon-pci-0100 Adapter: PCI adapter temp1: +76.0°C I have an HP Pavilion dv6, i7, amd radeon graphics. Please let me know if you need additional information. What could be different between the two Ubuntu additions that caused such a drastic change? Edit 1: Per @Paul's suggestion, I ran htop to try to narrow down the problem. Here is the result! This is about 10 minutes after boot-up, htop, yakuake, and a chrome page with 1 tab opened to this question are all that I have manually opened. The most taxing program to the CPU is htop itself. I think that the problem must lie elsewhere; my temps are already up to ~65C for the CPU and ~69C for the GPU, with nearly 0% CPU usage.

• Why does my root filesystem keep becoming read-only?

  - by Scott Severance

  I've lately been having an issue with my root filesystem becoming readonly. It happens some amount of time after boot. I don't know exactly when it happens, as I don't usually notice it until something such as suspending the computer or printing fails. It seems to be fairly random. Since most of my system is on that partition, I can't re-mount it without rebooting. After this happens, the system runs a fsck. Sometimes it prompts to fix problems; other times it apparently finds none. To troubleshoot, I've searched through the logs but found nothing relevant. This might be due in part to not knowing when the actual errors took place. The filesystem is apparently good to begin with, as when fsck runs its fixes it doesn't report any errors. I've scanned the disk with SpinRite. A while ago, SpinRite found and recovered from some bad sectors on the hard drive. I ran a level 4 scan (a thorough scan) after this probem appeared, but SpinRite found nothing. The SMART data reports that the disk is OK with 63 bad sectors. The number of bad sectors hasn't changed recently. I realize that the disk isn't in the best of conditions, and I have complete backups in case of catastrophic failure. Yet the lack of errors in the logs, combined with SpinRite's test results and the unchanged SMART data makes me think that this problem has some cause other than disk failure. Other than disk failure, what could cause my symptoms?

• Step 2 of instructions is not clear to me

  - by Albert Frye

  I want to make a bootable USB stick. I run the UUI. I see the instructions on this site: http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-windows Step 1 says: Select "Ubuntu Desktop Edition" from the dropdown list Okay, so the actual title of the drop down box is: Select a "Linux Distribution" from the dropdown to put on your USB I am pretty new to computers. 67 years old. Live alone. Bought my first computer 3 months ago. So I will have to assume that when the instructions say "Ubuntu Desktop Edition", that means the same thing as "Linux Distribution". Okay, No big leap there. So far, so good . . . . . . . So I pick the very first selection: Ubuntu 13.10 Desktop i386 I'm not sure why there are so many choices, but I'm guessing I'm pretty safe with the first one. It's for a Toshiba Satellite laptop 64 bit Windows 7. Okay, now for step 2: The instructions say: Click 'Browse' and open the downloaded ISO file. The message in the window just before the "Browse" button says: Browse to your ubuntu-13.10*desktop*i386.iso -- Okay, so where's that file? So I click "Browse" and start looking for that file. It is nowhere to be found. So where the heck is it?

• Accessing second hard drive

  - by Jonathan

  So I recently installed Ubuntu 10.10 64-bit on my computer. I installed it on my 60gb SSD hard drive, and in the installation it never acknowledged the existence of my second hard drive. The hard drive that I keep all my files on, and which I want to make my home folder if I can, is a Western Digital Caviar Black 1TB SATA 6Gb/s 64MB cache (WD1002FAEX). I've read the following: https://help.ubuntu.com/community/Mount but honestly cannot work out how to access the hard drive from my Ubuntu installation. I did have Windows 7 64-bit prior to installing Ubuntu. I have backed up all the files on the hard drive, but if I could just access them straight off that would be super cool. Does anyone know how I can use the second hard drive? Thank you for your help EDIT: The following directories are currently in my /dev/ folder: ati/, block/, bsg/, bus/, char/, cpu/, isk/, input/, mapper/, net/, pktcdvd/, pts/, shm/, snd/, and usb/ EDIT: Result from sudo fdisk -l Disk /dev/sda: 60.0 GB, 60022480896 bytes 255 heads, 63 sectors/track, 7297 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000d2dfd Device Boot Start End Blocks Id System /dev/sda1 * 1 6994 56174592 83 Linux /dev/sda2 6994 7298 2438145 5 Extended /dev/sda5 6994 7298 2438144 82 Linux swap / Solaris @djeykib So very close to fixing it.. unfortunately on the last command you gave it says this: $ sudo apt-get install linux-lts-backport-natty Reading package lists...

• Random shut down? Asus N53J Laptopi

  - by Mr.Y

  My Laptop is pretty new and today it random shut down on its own. I was surfing the net and the computer shut down on its own (Like losing power, without any warning). It was the 2nd time, the first time was 3 weeks ago. Btw it happens during cold days. I remember one time I was unable to turn on my laptop at all. So I'm pretty sure it's not related to heat issue... could it be the laptop is too "cold"? My room temperature is around 17=18 degree on average :P edit -I use Windows 7 Professional. -I run memtest86 once and it passed. -I run my laptop WITHOUT battery all the time.

• How can I properly create /dev/dvd?

  - by chazomaticus

  Certain programs look for /dev/dvd by default to find DVDs. When I first boot my computer without a DVD inserted, /dev/dvd exists and points to the correct place (/dev/sr0). However, when I insert a DVD, /dev/dvd disappears. I'd like it to stick around so I don't have to navigate to /dev/sr0 in programs that are looking for DVDs. How do I ensure that the /dev/dvd symlink exists and points to the right place? It looks like I can add something to /etc/udev/rules.d/70-persistent-cd.rules. This site gives a couple of examples, but the 70-persistent-cd.rules file says "add the ENV{GENERATED}=1 flag to your own rules", which isn't part of the examples. The man 7 udev page is impenetrable to me, and I'm not convinced the linked page gives 100% of the information I need. So, what can I do on a modern, Ubuntu 12.04 (or later) system to make /dev/dvd always exist and point to the right device? EDIT: Is it as simple as adding ENV{GENERATED}=1 to the rules in the linked page, something like this: SUBSYSTEM=="block", KERNEL=="sr0", SYMLINK+="dvd", GROUP="cdrom", ENV{GENERATED}=1 Is that the right information for modern Ubuntu? What is ENV{GENERATED} doing there, when it wasn't generated, but hand-written?

• How do I use an API?

  - by GRardB

  Background I have no idea how to use an API. I know that all APIs are different, but I've been doing research and I don't fully understand the documentation that comes along with them. There's a programming competition at my university in a month and a half that I want to compete in (revolved around APIs) but nobody on my team has ever used one. We're computer science majors, so we have experience programming, but we've just never been exposed to an API. I tried looking at Twitter's documentation, but I'm lost. Would anyone be able to give me some tips on how to get started? Maybe a very easy API with examples, or explaining essential things about common elements of different APIs? I don't need a full-blown tutorial on Stack Overflow; I just need to be pointed in the right direction. Update The programming languages that I'm most fluent in are C (simple text editor usually) and Java (Eclipse). In an attempt to be more specific with my question: I understand that APIs (and yes, external libraries are what I was referring to) are simply sets of functions. Question I guess what I'm trying to ask is how I would go about accessing those functions. Do I need to download specific files and include them in my programs, or do they need to be accessed remotely, etc.?

• does any sync software find files that have moved paths within a folder?

  - by kpierce8

  Say I have a pictures folder which I reorganized on one computer. I'd like to use that directory as the base and compare it with another version on a backup drive. Will any sync/compare program find that a file in one folder has moved locations within a compare folder. For instance say I reorganized my pictures from trips into folders by year with the trips folders inside each year folder. If I use a regular compare utility I wind up with two copies of everything that's moved in different locations.

• IPSec on Domain Controllers and Trusted Domains

  I am looking at configuring IPSec as follows: Isolation Request authentication for inbound and outbound connections Computer and user (Kerberos V5) I am looking to do a blanket deployment across all servers and domain controllers. Workstations I will leave as not set. What impact in terms of the domain controllers with the 2-way forest trust do think I would see? Should I exclude the IP addresses of the trusted domain controllers? I don't want to stop communication between the current and trusted forest, however I do want IPsec to be used within the current forest on all servers. The trusted forest is running 2008 R2 and the current forest is 2012 R2.

• Saving Photoshop workspace doesn't remember docked panel state

  - by johnh

  A friend of mine has recently setup his computer with a fresh install of Windows 7 and Photoshop CS5. He's having a strange issue with saved workspaces not remembering the state of docked panels. As an example, he's docked several panels on the right of the screen. The Layers panel is docked but is open, showing all layers in the document. If he saves this as a workspace, closes and reopens Photoshop and loads the workspace, the Layers panel is docked but is closed. It's not the only panel this is happening with. It's not a big problem but he's having to open 4 panels and drag them to the appropriate height each time he starts Photoshop. Does anyone know of a possible fix for this? Any insight would be great.

• Windows 7 x64: 3900mb of 4gb RAM usage, even when (almost) nothing running.

  - by user34630

  As the title suggests, I am having a problem with memory usage. I have had my computer (Vaio AW11Z/B laptop) for over a year now, and it was running perfectly until I guess a day or two ago. Now programs randomly crash, the mouse lags around the screen and the memory usage is going through the roof for no apparent reason. I am having exactly the same problem as this guy: http://social.answers.microsoft.com/Forums/en-US/w7performance/thread/1f716693-0a46-473e-9dc0-8c2b1a058443/. I think he explains it better. Anyone had a similar issue? What's going on? I don't think it's a virus/adware thing. Thanks very much for any help.

• Map a drive to root of a server (\\sever) in Vista

  - by Andy T

  Hi, In Win XP, I can very easily map a network drive to the root of my NAS server. I browse to it in Explorer (\192.168.1.70), choose "Map Network Drive", choose the drive letter, done. In Vista, this does not seem possible. I have to go "Map Network Drive" from 'Computer', then enter the address, but it will only let me map to specific shares (sub-folders off of the server root) and NOT to the server root share. Since my NAS has built-in shares (music, photo, video, etc.) then I would have to have drive letters for all of these, which I absolutely don't want. Can anyone tell me - how come I can easily map to the server root from XP, but not in Vista? Is there something fundamentally different in the networking across the two OS's? Or do I just need to do things a different way? Hope someone can help. Thanks, AT

• How useful is PXE booting?

  - by J. T.

  Hi All, How fast is booting over PXE?. Is it conceivable to boot a linux installation? Does it take a long time? I have never really looked into it at all, but I was considering setting up a compiler farm and thought this might be interesting to try. Does one have a main computer that the PXE answers to to get its image? Can you have multiple PXE images to pick from? Thanks!

• How do I fix broken installation?

  - by Daniel

  Let me start off by saying I'm dual booting 11.04 and Windows 7 on a Thinkpad T61p. The problem may have arisen when I hit the power button during normal startup. I'm fully aware how stupid this is. I don't know why I did it. I did it. Now, I can't get in to Ubuntu. Windows works fine. But when I try to start Ubuntu normally, it seems to run some checks, and does not start up. Sometimes, I see a black screen, and it tells me that it's running certain checks, and then, [ok]. Like... Battery Check Somethingorother [ok] It'll give me 1-5 of these. And then it just does nothing, and I have to turn it off. When I try to start in safe mode... I tried low graphics mode, and after going through a couple of dialogue boxes, I'm brought right back to the safe mode dialogue box. And if I hit 'resume,' a shell pushes up (still that grey on black "your computer is broken" type shell) and asks me to log in. I do, and try to run unity. It tells me something along the lines of: WARNING no DISPLAY variable set and then sets it to " :0" , which doesn't work. And then I can't do anything, really, and I have to restart. (I don't know how to do this from the command line, so I just hard reset. That command would be helpful). Does anybody have any idea how I can get Ubuntu working right again? FTP is less pleasant in Explorer than it is in Nautilus or w/e it is now.

• How to prevent HP Photosmart Essential from launching on removal drive insertion

  - by David Boike

  My in-laws bought an HP computer loaded with HP junk, and it's giving me a headache. When they insert a camera memory card into their printer, the Auto-Play dialog comes up, but it also launches the HP Photosmart Essential application, which is a piece of trash. It will NOT launch properly just normally from the taskbar, so that makes it pretty useless. I tried uninstalling it, but then when you insert a memory card, a Microsoft Help window comes up saying how to reinstall HP Photosmart Essential!! Is there any way to find the registry key (I assume) that allows a program to be launched when a memory card is inserted?

• The most efficent ways for drawing lines all day long with OpenGL

  - by nkint

  I'd like to put a computer screen that is running an OpenGL programs in a room. It has to run all day long (not in the night). I'd like to draw lines that are slowly fading in the background. The setting is simple: a uniform color background (say, black) and colored lines (say, white) that are slowly fading out. With slowly I mean.. hours. Say that the first line I draw is with alpha 255 (fully visible), after one hours is 240. After 10 hours is 105. One line could have 250 points and there will be like 300 line in one day. For now I have done a prototype with very rudimentary method like: glBegin( GL_LINE_STRIP ); iterator = point_list.begin(); for (++iterator, end = point_list.end(); iterator != end; ++iterator) { const Vec3D &v = *iterator; glVertex2f(v.x(), v.y()); } glEnd(); More efficient method?

• Printer offline until spooler service is restarted multiple times

  - by Zian Choy

  When I try to print from my ThinkPad to a printer shared through a Windows 7 Homegroup hosted by a desktop computer, I often have to restart the Print Spooler service several times before the job will go through. In particular, this problem occurs when the desktop is in sleep mode when the print job is started and then brought out of sleep mode after the print job has been kicked off. Both computers are running Windows 7 32-bit edition with the latest patches. I have tried the following with no improvement: SNMP registry hack (see MS KB for details) Following the instructions in a blog post entitled "Sharing Printers on Vista 64-bit" Looking at Printer offline until spooler service is restarted
