  • Is it safe to configure "Shutdown" on "When laptop lid is closed" ?

    - by Takkat
    To setup a laptop owned by a complete PC novice any settings that may become hard to tackle remotely need to be avoided. The laptop will be administrated via SSH. One thing in my list are problems arising from improper wake-ups from suspend or hibernate as they may also affect network accessibility. This is why I thought setting up power management to "shutdown" on closing the laptop lid could be a good idea. However I am not sure if this is a safe way to do. What problems in addition to software not closing properly (and thus not saving their data) could I be faced if I proceeded as planned?

  • Xubuntu fails to stay awake when the machine is under load

    - by Alex
    I have the following problem with a fresh install of Xubuntu 12.04: I set up power management options so as to send the machine to sleep after it's been idle for a while. My intention was to have it finish some lengthy numbercrunching and then fall asleep late at night when nobody's present to shut it down. What actually happened, however, is that the machine goes to sleep whenever the desktop session has been idle for the specified amount of time, and it does not seem to care at all about CPU load, and I had to disable sleep altogether. Is there any way to fix this?

  • My Laptop Battery Does Not Charge

    - by Oo Nwoye
    I am using a HP Pavilion and Ubuntu 11.10. I have been using Ubuntu for about a year. Recently (in Nov or there about), I noticed my battery never charges fully no matter how long it has been plugged in. I thought it was a problem with the power pack. However, after changing it, the problem is still persisting. I upgraded to 11.10 form 11.04 at about the same time so I do not know if this is a software or hardware issue. How do I solve this? This problem has been written about in various forms Laptop battery not charging after update?. Please help me or find someone that can.

  • Battery life decreased after upgrade to 11.04

    - by bruno077
    After upgrading from Ubuntu 10.10, my battery life has decreased dramatically. There was a bug in Ubuntu 10.10 where the Load Balancing Tick and Kworker would interrupt and wake-up the cpu too much, and this wasn't normal. I applied a gnome-power-manager fix back then, following this question, which leads to this bug report, and battery life increased to 3.5 hours. I'm getting around two hours of battery-life in Natty, and calling Intel's powertop reveals that this bug is back. Is there a fix for Natty yet? I have a Core 2 Duo ULV, Thinkpad Edge 13

  • suspend error on 14.04 LTS

    - by user1450663
    I've looked around and seems like various problems around suspend are wide spreaded for 14.04 release, nevertheless I haven't seen exactly my problem reported, nor my laptop model mentioned. So, the problem. When I press sleep button system seems to be going into suspend, i.e. screen goes black, it stops responding on the keyboard and wireless LEDs turn off, however the power LED doesn't go into suspend state and CPU fan also keeps spinning. But unlike the other problem described here https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1315435 when I close the lid and reopen it - system wakes up and goes back to normal locked screen state, so reboot is not needed. System details: This is a clean freshly installed Ubuntu 14.04, 32bit Laptop Dell D630 kernel 3.13.0-34-generic

  • Limiting what resumes computer from suspend

    - by user1399195
    I'm having a ton of trouble getting Suspend to work with my laptop. I want to start using Ubuntu but this is a pretty important aspect since I take my laptop with me everywhere. Anyways, I wanted to narrow down the possible problem with my laptop. What happens is that when I suspend my computer, within seconds, it just boots back up. I have changed /proc/acpi/wakeup to where everything is disabled but that did nothing. Is there a way where I can disable every feature from waking up the laptop except the power button?

  • Linksys WAP54G v3.1 no access, power and link LED solid

    - by user142113
    I'm managing the Network of a small enterprise. A Linksys WAP54G v3.1 used to provide the WiFi network. I was called, because the device did not provide a WiFi network anymore. I first of all tried to ping the device via LAN, but there was no reaction. I've frequently reconnected the AP to the mains and always the POWER and the LINK LED keep solid, even if no network cable is connected. What I've done yet: Reset as documented: Pressed the RESET button for 10 seconds. After that I have tried to access the AP with a direct cable connection to my computer, that I've set to a static ip of 192.168.1.240, but i got no ping response on the default IP 192.168.1.245. Furthermore ipconfig reports "media disconnected". More complex reset method as described here http://bruceshankle.blogspot.de/2005/12/how-to-reset-linksys-wap54g.html as well had no effect. also tried to ping 192.168.1.1 without success Tried this method: http://www.daniweb.com/hardware-and-software/networking/threads/142437/linksys-wireless-access-point-problem#post680245 but there was no ping response when powering up. As well the tftp transfer timed out Finally tried to short pin 15 and 16 of the flash chip on the bottom side of the AP mainboard while booting to provoke a Checksum error. This should lead to the possibility to upload a firmware with tftp, as the AP stops booting and waits for a tftp connection on 192.168.1.1. But I've had no success. As well i've put pin 15 and 16 to ground while booting, also without an effect. After all that I still can't ping the AP, ipconfig still tells me "media disconnected". The POWER and LINK LED are solid. I would appreciate your answers

  • Windows XP - Power surge on hub port

    - by Swift-Tuttle
    Since last few weeks I constantly get this error, as status bar balloon: Power Surge on Hub Port - A USB device has exceeded the power limits of its hub port. Due to this now I am unable to access any USB devices properly, they get disconnected intermittently. I did quite a few things to resolve this problem, firstly obviously through the Windows help. I even tried all the things told on the Microsoft website(which essentially says is to check and update the driver) but in vain. One suggestion, I found when I google'd was to disable the USB2 controller through the Device Manager and since at every startup the System configuration comes up complaining that it has been changed etc.(On that same site it is mentioned to ignore this message.) But after everything I still cant solve this problem. Any help is much appreciated. The system is installed with Windows XP service Pack 3 and all the updates till last month. Please let me know if any other hardware info is required. **UPDATE** My laptop is about 5 years old now, its an HP with Celeron 1.4G processor. Windows XP SP3 installed. All latest windows updates installed. 2 USB ports available. BIOS is HP 68DTD ver F.0A Do I need to update my BIOS from somewhere ? or is this a hardware problem altogether?

    Hi everybody, i was planning to buy a SAS system made of two 15k RPM disks in Raid 0 configuration to give a boost to my s.o. and my apps... but after i saw that article on Coding Horror, i've started to thinking if a new 2nd generation SSD could do the same job, or even better... Does anybody have any information to help me decide?

  • The Most Common and Least Used 4-Digit PIN Numbers [Security Analysis Report]

    - by Asian Angel
    How ‘secure’ is your 4-digit PIN number? Is your PIN number a far too common one or is it a bit more unique in comparison to others? The folks over at the Data Genetics blog have put together an interesting analysis report that looks at the most common and least used 4-digit PIN numbers chosen by people. Numerically based (0-9) 4-digit PIN numbers only allow for a total of 10,000 possible combinations, so it stands to reason that some combinations are going to be far more common than others. The question is whether or not your personal PIN number choices are among the commonly used ones or ‘stand out’ as being more unique. Note 1: Data Genetics used data condensed from released, exposed, & discovered password tables and security breaches to generate the analysis report. Note 2: The updates section at the bottom has some interesting tidbits concerning peoples’ use of dates and certain words for PIN number generation. The analysis makes for very interesting reading, so browse on over to get an idea of where you stand with regards to your personal PIN number choices. 8 Deadly Commands You Should Never Run on Linux 14 Special Google Searches That Show Instant Answers How To Create a Customized Windows 7 Installation Disc With Integrated Updates

  • Caching strategies for entities and collections

    - by Rob West
    We currently have an application framework in which we automatically cache both entities and collections of entities at the business layer (using .NET cache). So the method GetWidget(int id) checks the cache using a key GetWidget_Id_{0} before hitting the database, and the method GetWidgetsByStatusId(int statusId) checks the cache using GetWidgets_Collections_ByStatusId_{0}. If the objects are not in the cache they are retrieved from the database and added to the cache. This approach is obviously quick for read scenarios, and as a blanket approach is quick for us to implement, but requires large numbers of cache keys to be purged when CRUD operations are carried out on entities. Obviously as additional methods are added this impacts performance and the benefits of caching diminish. I'm interested in alternative approaches to handling caching of collections. I know that NHibernate caches a list of the identifiers in the collection rather than the actual entities. Is this an approach other people have tried - what are the pros and cons? In particular I am looking for options that optimise performance and can be implemented automatically through boilerplate generated code (we have our own code generation tool). I know some people will say that caching needs to be done by hand each time to meet the needs of the specific situation but I am looking for something that will get us most of the way automatically.

  • Can I run into legal issues with random names?

    - by Nathan Sabruka
    I'm currently building a game whose NPC's are going to be assigned a random gender and a random name for the right gender. To do this I will be using a "database" of names (actually a text file with tuples). There would also be a list of last names, which will be added to the first name also randomly. My question is the following. Suppose one such random name is "George Bush", and this person has been randomly assigned the job of president. As you can see, this could easily be seen as having been "copied" from a real-life person. The main issue is this. Names will be randomly-generated, yes, but the seed for random-number generation will be constant. In other words, the name of an NPC would be randomly-generated, i.e. I wouldn't choose it, but it would be the same for every player. Could this get me in trouble? We cannot verify all possible names, since the generated number of NPC's could be potentially limitless (new NPC's are being created whenever needed).

  • Seeking solution for printing-reporting .NET

    - by Parhs
    I am developing an application that prints in separate threads in extreme cases about 20-25 pages per minute to various thermal printers. Currently templates for these are XAML xps documents. All printers have graphics drivers that support EMF/GDI printing. So GDI-EMF is done by operating system resulting in slower performance. Sending raw text for printing is another good solution but doesnt work always , because some clients have old chinese thermal printer that nobody support thus impossible to change codepage / emulation. So it doesnt work always. Also most computers running my software are low end ATOM CPU. So I am thinking to return to GDI, EMF printing and have both Text-Only reports and EMF reports. Another reason i want EMF is because here receipts are signed by Electronic Fiscal Memory device.Most of these dont do good job extracting text from XPS as they dont follow the standard but how windows convert GDI to XPS.Even with text-only mode some of them dont support all character encodings and are impossible to send paper cut command after the sign. I know that using a reporting engine would solve rendering problem but I dont want to buy one. All I want is to be able to show tabular data and insert an image and replaced text.I know there is StringTemplate that could do the generation of template but the problem is i should parse somehow the template and render it using GDI commands. Is there any other solution/approach for this ? Or is there anything ready ?

  • 3D Vector "End Point" Calculation for procedural Vector Graphics

    - by FrostFlame64
    Alright, So I need some help with some Vector Math. I've developing some game Engines that have Procedural Fractal Generation for Some Graphics, such as using Lindenmayer Systems for generating Trees and Plants. L-Systems, are drawn by using Turtle Graphics, which is a form of Vector graphics. I first created a system to draw in 2D Graphics, which works perfectly fine. But now I want to make a 3D equivalent, and I’ve run into an issue. For my 2D Version, I created a Method for quickly determining the “End Point” of a Vector-like movement. Given a starting point (X, Y), a direction (between 0 and 360 degrees), and a distance, the end point is calculated by these formulas: newX = startX + distance * Sin((PI * direction) / 180) newY = startY + distance * Cos((PI * direction) / 180) Now I need something Similarly Equivalent for performing this Calculation in 3D, But I haven’t been able to Google anything that could show me how to do this. I'm flexible enough to get whatever required information is needed for this method calculation, in any reasonable form (Vector3, Quaternion, ect). To summarize: Given a starting point/vector position in 3D space (X, Y, Z), a Direction in 3D space (Vector3, Quaternion, ect), and a Distance, I need to find the “End Point” in 3D Space. Thank you for your time and help.

  • Basic procedural generated content works, but how could I do the same in reverse?

    - by andrew
    My 2D world is made up of blocks. At the moment, I create a block and assign it a number between 1 and 4. The number assigned to the nth block is always the same (i.e if the player walks backwards or restarts the game.) and is generated in the function below. As shown here by this animation, the colours represent the number. function generate_data(n) math.randomseed(n) -- resets the random so that the 'random' number for n is always the same math.random() -- fixes lua random bug local no = math.random(4) --print(no, n) return no end Now I want to limit the next block's number - a block of 1 will always have a block 2 after it, while block 2 will either have a block 1,2 or 3 after it, etc. Before, all the blocks data was randomly generated, initially, and then saved. This data was then loaded and used instead of being randomly called. While working this way, I could specify what the next block would be easily and it would be saved for consistency. I have now removed this saving/loading in favour of procedural generation as I realised that save whiles would get very big after travelling. Back to the present. While travelling forward (to the right), it is easy to limit what the next blocks number will be. I can generate it at the same time as the other data. The problem is when travelling backwards (to the left) I can not think of a way to load the previous block so that it is always the same. Does anyone have any ideas on how I could sort this out?

  • Generated 3d tree meshes

    - by Jari Komppa
    I did not find a question on these lines yet, correct me if I'm wrong. Trees (and fauna in general) are common in games. Due to their nature, they are a good candidate for procedural generation. There's SpeedTree, of course, if you can afford it; as far as I can tell, it doesn't provide the possibility of generating your tree meshes at runtime. Then there's SnappyTree, an online webgl based tree generator based on the proctree.js which is some ~500 lines of javascript. One could use either of above (or some other tree generator I haven't stumbled upon) to create a few dozen tree meshes beforehand - or model them from scratch in a 3d modeller - and then randomly mirror/scale them for a few more variants.. But I'd rather have a free, linkable tree mesh generator. Possible solutions: Port proctree.js to c++ and deal with the open source license (doesn't seem to be gpl, so could be doable; the author may also be willing to co-operate to make the license even more free). Roll my own based on L-systems. Don't bother, just use offline generated trees. Use some other method I haven't found yet.

  • What is wrong with those crontabs?

    - by Guillaume Boudreau
    I want my projectors to Power On before the mall opens, and Power Off when the mall closes. So I created crontab entries (that I placed in /etc/cron.d/mall), but today (Thu Nov 22 18:58:29 EST 2012 is the current date on that server), the power-off.sh script got executed at 17:20 (see syslog excerpt below). Being Thu, Nov. 22, I would have expected the power-off.sh script to be executed at 21:20, per the 4th crontab line below. Why did power-off.sh execute at 17:20? What is wrong with my crontab entries?

  • How to disable Power off/Power on sound on Android phone? [closed]

    - by yvolk
    My Android phone (Android v.2.1) produces loud sound both before Power off and after Power on (boot) is being completed. I don't want to turn the sound off before reboot/powering it off and to turn sound on after reboot every time I'm restarting my phone. I just want to get rid of these sounds forever :-) How can I do this (maybe executing some script, changing some properties... preferably without rooting my phone)? Update: Thank you Christopher Orr! I've also found some information that partially allows to achieve what I'm looking for (on androidforums.com): "if you are going into SettingsSound & displayNotification ringtone that sets your notification tone for app updates, power on (rebooting) etc. If you want to change notification for messages you would have to go into messaging and then hit the menu key for notification option. You can do the same for email accounts as well." So I disabled Power on/off sounds (plus something else... but I didn't notice undesired side effect yet...) with built-in settings.

  • Laptop Charger Not Recognised Properly on Samsung NP900X3F

    - by user193732
    Firstly thanks for your time. Secondly, having an issue with my power charger on my Samsung Series 9 NP900X3F. When I boot into Ubuntu with the charger plugged in it recognises it as charging. When I unplug the charger after this it is still says it is charging. If I suspend in Ubuntu then plug/unplug during this suspended state it recognises it, but not during normal running. If I knew a little more I'm sure I could grab logs and find out what the difference between wake on suspend and normal running is, but alas I need help! I also am having issues with my keyboard backlight via the fn keys, but that I care about far less. Thank you very much. Linux mikey-900X3F 3.12.0-031200rc1-generic #201309161735 SMP Mon Sep 16 21:38:21 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux (I upgraded my kernel version to remove heinous horizontal artefacts I was getting) Happy to list more info about my system, ima bit of a noob. I did try searching however I can't find any questions at all about my system or related models with the same issue.

  • screen does not wake up after suspend/ brightness will not adjust

    - by Nathan
    My computer is one of these: http://www.newegg.com/Product/Product.aspx?Item=N82E16834230467 Asus Zenbook UX32A-DB51 Just bought it yesterday. Set to "suspend" when I close the lid, but when I open it up again I just get a black screen. Pressing the power button doesn't work, not does clicking the mouse or any key combination. The same is true if I leave the computer until it suspends. Black screen, no response, have to reboot. I also can't seem to adjust the brightness. I put "brightness up" and "brightness down" function keys in, and when I push them it shows the brightness level as going up and down on the meter, but the screen does not actually become more or less bright. I am totally new to all of this. Please tell me what additional information you need to help me and where I can find it. Thanks! Edit: Tried the following: sudo gedit /etc/default/grub Change the line GRUB_CMDLINE_LINUX="" into GRUB_CMDLINE_LINUX="acpi_osi=Linux" sudo update-grub Restart your linux And "acpi_backlight=vendor" both to no avail.

  • Why does 12.04 try but fail to hibernate, even after I enabled hibernation?

    - by Roger Davis
    Regarding the below (-----) info from another post, my system will try (as is said below) to hibernate, but it won't get all the way there. Hard drive activity stops, but it does not shut down. If I turn the power off, then back on, it will start, but I have to "restore previous session" in the browser and other open apps don't restart, with the accompanying hassle. So because it tries, will the suggested fix then cause it to work correctly, or is the literal "try" not really what he means?!? PLEASE NOTE - this is a desktop system, not a laptop. Before enabling hibernation, please try to test whether it works correctly by running pm-hibernate in a terminal. The system will try to hibernate. If you are able to start the system again then you are more or less safe to add an override. To do so, start editing sudo nano /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla Fill it with this [Re-enable hibernate by default] Identity=unix-user:* Action=org.freedesktop.upower.hibernate ResultActive=yes Save by pressing Ctrl-O and exit nano by pressing Ctrl-X Restart and hibernation is back!
