• Removing BIOS Post Messages

  - by Steve

  I am working on a project where a standard x86 desktop system will boot and run a single program until it is shut down. I would like to remove all the bios post messages so that it looks a little more "finished" and cleaner when it starts up. I was hoping that there might by a standard implementation/terms to know about so I can avoid having to dig through every manual to see if there are options, or get some advice on a standard set of tools I should be using. I was thinking about getting a board that has an image that covers up the post messages until you press a key and trying to customize it to all black, but it's not clear if this is a good direction. I started looking for OEM motherboards but my searches were filled with standard commercial stuff, or seemed to be way to big for my toy project. What is the best way to go about removing all the bios post messages and just having a blank screen or "loading" message until OS loads?

• USB flash drive showing empty but half of the capacity is in Used

  - by tamakisquare

  Not sure if I should post my question in superuser, but it looks like the most appropriate place among all StackExchange sites. I have a 16GB Kingston DataTraveler USB drive. When I tried to use it this morning, it showed up nothing in there but yet its details showed that half of the capacity was in used. I tried it with OS X, Ubuntu, and Windows 7 and the results were the same. I tried to create a new folder and it worked. Apparently, the drive is working but somehow not showing my previously stored data. Note that I was still using the drive last night and there wasn't any problems. Following @rob's suggestion, du -h gave me: 16K ./.Trashes 960K ./.Spotlight-V100/Store-V1/Stores/2620683B-A38B-42F4-A247-45CAF4826ADE 976K ./.Spotlight-V100/Store-V1/Stores 1008K ./.Spotlight-V100/Store-V1 1.0M ./.Spotlight-V100 1.1M And, df -h gave me: /dev/sdb1 15G 7.9G 7.1G 53% /media/KINGSTON Confirming what I reported. Anyone got a clue/answer to this issue? Thanks.

• Game with changing logic

  - by rsprat

  I'm planing to develop a puzzle like mobile game (android/ios) with a different logic for each puzzle. Say, for example one puzzle could be a Rubik's cube and another one a ball maze. Many more new puzzles will appear during the life of the game, and I want the users to be able to play those new puzzles. The standard way for managing this would be through application updates. Each time a new puzzle or bunch of puzzles appear, create a new update for the app that the user can download. However, I would like to do it in a more transparent way. When a new puzzle appears, the basic info of the puzzle would be displayed in the app menu, and the user would be able to play it by just clicking it. What comes to my mind is that the app would automatically download a .dll or .jar and inject it in the application at runtime. Is that even possible? Are there any restrictions from the OS? Is there a better way for solving it? Thanks alot

• Run command on init and restart on errors

  - by chersanya

  I have internet access on my PC through proxy through SSH, so every time I need to execute ssh -L PORT:SERVER:PORT LOGIN@SERVER and then type a password. After each network failure or reconnect this command has to be executed again. I've got bored of it and look for a way to do this automatically: first run this after boot (it doesn't seem to be a problem - put this command in some init file and that's all) and then rerun it (if possible, then type password) on each network failure. Is it possible, and how? OS Linux (Debian)

• What is the procedure to replace a failing hard drive in a RAID array?

  - by slayton

  3 years ago a co-worker setup a software RAID-6 array on Ubuntu 9.04 and I'm getting messages from the OS that the drive has bad sectors and should be replaced. I'd like to remove this drive and replace it with a new drive, however, I have never done this before and I'm terrified that in the process of fixing the array I'm going to end up ruining it. I know the device ID of the array and I know the device IDs of the individual drives in the array. Additionally I physically have the bad drive. What are the steps to replace the bad drive with a new drive and get the array running again?

• Can I sleep one of the displays on a dual-monitor setup? [duplicate]

  - by archedpenguin

  This question already has an answer here: Can I sleep one of the displays on a dual-monitor setup (running Windows 7)? 4 answers I want to be able to 'put the display to sleep' on one of my two monitors when it isn't needed, so it doesn't distract me or use unnecessary power. Ideally, the display would be asleep, but the OS would remain in dual-monitor mode, so I could still have a variety of windows open in the sleeping monitor's display space, which would mean I wouldn't have to keep switching between single- and dual-monitor modes. Its the same as "Can I sleep one of the displays on a dual-monitor setup (running Windows 7)?" I just wasn't sure I could comment on such an old thread. None of the answers there provided a perfect solution and I was wondering if there is now a solution available.

• Logging in over ssh in a different session?

  - by Jordan Reiter

  I don't know exactly what the correct term is, but I notice if I log in to a remote SSH server, then close the window, open a new one, and log into that server again, my bash history and user processes appear to be different. For instance, if I started a background process I can't get back into it, or something I typed won't show up in my bash history. The problem is for some reason occasionally something happens to my remote session and instead of being disconnected the session just hangs; I have to close the window and open a new one to reconnect. As a result sometimes it means a long running process basically is "lost" since I can't get back into it. Is there any way to set it up so that when I log back in I log back in to the same "session"? This is using OS X Terminal.

• Install Windows XP without disk

  - by Pearsonartphoto

  So, my kid's computer has Windows XP, with no disks. I'm pretty sure it has some viruses on the computer, of the type that don't seem to come out despite trying multiple anti-viral programs on it. I'm ready to just format it and start over again. I have a license sticker on the box, but no media to install it. I strongly suspect the license is OEM, but I don't have any proof. What suggestions would you have? I should say, the computer originally belonged to a business, is probably 6 years old, and I am willing to pay a small charge if required. I don't want to change the OS installed either.

• Logitech SetPoint update seems to be hanging

  - by Rod

  I've just gotten a new Logitech Wireless Wave Combo MK550 mouse and keyboard. I pulled it in, and have installed the software that came on the CD, which is SetPoint 6.15. After installing it, it said that it had an update, so I started the installation for that. Now it's at a point where it says, "Approximately 30 second remaining...". It has been that way for 30 minutes, not 30 seconds. So, what's going on? I'm installing this on a Windows 7 Home Premium system, 64-bit OS.

• Recommended laptops for system admins?

  - by 80skeys

  Hey all - I'm in the market for a new laptop and wanted to get some recommendations. I'm a Linux sysadmin and this laptop is primarily for work related use, working from home, after hours, occasional trips to the data center, etc. We all know the drill. My typical setup includes various utilities and tools plus multiple partitions for booting different OS's including VMware. Need serial port of course, DVD-RW, and all the usual stuff we use in our daily routine. I'm kinda thinking a Thinkpad T510 but open to other suggestions! Brief explanation of why you suggest some particular brand and configuration is appreciated.

• Windows 7 very slow after restart, but fine after complete shutdown?

  - by lkm

  I have a Dell pc running Windows 7 with the Intel i3 processor. Whenever I restart the computer, the os crawls. For example, I move the mouse and then I see it move on the screen 10 seconds later... Everything runs slowly. This happens only on a restart (it's fine when I turn it on after it has been shut down). Any ideas what is causing this (I haven't installed any new software since buying it). Does it sound like a hardware or software issue?

• TV Card Problem

  - by MladenB

  I have DVB-T card (CE9500B1) and it doesn't work. I've tried everything I knew (but I don't know much). It doesn't show any problem, but shows "No Signal". I used another TV card USB, found channels, put mine card again, and again nothing. I don't think it's broken, when I put USB in my laptop, it recognizes it. Also, these little lights on USB are never turned on. OS is Win 7. Help, please.

• Vista Startup - Cannot Find the File Specified

  - by Redmastif

  Yesterday I restarted my laptop because my Wi-Fi catcher wasn't working correctly, and when the computer reached the login screen, instead of showing my user account it said "Cannot find the file specified". I rebooted and ran the Startup Repair and Memory Diagnostics but nothing showed up. I also took the battery out for a minute and tried again but still no luck. The weird thing is that I cannot even boot into safe mode, it still shows the same error. I don't remember downloading or opening anything suspicious recently, and I have 3 different cleaners/anti-malware programs as well that I usually run about once a week. I did go into the registry recently but I didn't modify or delete anything as I was only checking to see if I had a certain key in it. I have a Dell laptop running Vista Home Basic SP2. If I have to I can reinstall the OS with the CD or even take it to Best Buy but I'd rather try and fix it first. Thanks.

• Debian Based Server not booting, soon after GRUB screen it restarts?

  - by Krauser

  I have tried running memtest, it start get about half way then abruptly restarts. I assume this is not a problem with the OS itself but rather a hardware issue, I have checked various logs when after about 10 reboots it starts ok, /var/log/kern.log /var/log/syslog /var/log/dmesg All I get is: EXT4-fs(sdc1): re-mounted. Opts: errors=remount-ro restart So I ran fcsk on the drive, to check if the fs was failing and it was fine. Really don't know how to find why the server is continuosly restarting andif I get lucky it will boot up.

• Boot failure on Ubuntu 11.04

  - by B Seven

  I was using my laptop with Ubuntu without problem for a few months. I did not update any software or install any OS updates. This morning when it started, I got error: no such device:.... error: no such disk error: you need to load the kernel first. Press any key to continue... Then takes me back to GRUB menu. Both Ubuntu option and recovery mode option show the same thing (above). What does this mean? How do I fix it? Since I did not install anything new, does it mean the SSD is dying (again)? How to check the SSD to and fix any file system errors? Ubuntu 11.04 EDIT: Just remembered something: when the system was shutting down, it did not turn off. There were a bunch of weird output statements, and I assumed the system had shut down so I turned it off with the power button. Perhaps something got corrupted because of that.

• Extended display - nightmare

  - by user206343

  I have been struggling for quite a while, and I hope one of you can shed some lights on my issue. I am using Xubuntu 13.10 (Ubuntu 12.04LTS behaves the same way, higher version wouldn't install, LinuxMint didn't install, Fedora didn't install). I am trying to set extend display for two dell monitors 1900x1200. It works great when in mirror mode, but I just cannot extend the display. Either one monitor goes to sleep and the other is unresponsive, or both work but are unusable. This is a link to the picture of my monitors in mirror mode This is link showing what happens after I try to extend the desktop I get the same results if I use aRandr or the built in configuration utility. I have an ATI Radeon X300 card. I cannot use proprietary Catalyst drivers (I would have to use the legacy ones, which would force me into using much older version of the OS). Extension is possible with Windows. I am hoping someone can come up with tweaks that would allow me to run an extended desktop. I truly love Xubuntu (and Ubuntu, unfortunately, Unity is a bit too heavy for my old PC, and I have to run in 2D mode, so 12.04 is as high as I can go). I have tried everything I could find online, but nothing worked thus far. I believe some configuration or something I am missing might work. Please, if you have any idea, do not hesitate. Thanks guys.

• Just installed Ubuntu 12.04. When booting, all I get is a black screen with cursor

  - by user66378

  Installation appears to go fine. After rebooting, I get my motherboard loading screens, but when it comes time for Ubuntu to boot, I just get a black screen with a blinking white underscore in the top-left - same as I got when waiting for the install CD to load, except it lasts forever. The only keypress it seems to recognize is ctrl+alt+del, which reboots. Letters don't register, function keys w/ or w/o modifiers do nothing. I've installed Ubuntu 12.04 twice and got the same error. The first time, I installed it as the only OS, and had it take up the whole disk. The second time, I installed Windows 7 first, then Ubuntu by specifying custom partitions. After this install, it would boot straight to Windows without showing grub. I used EasyBCD to add the Ubuntu installation to grub, and this got grub to show, and let me select it, but it led back to the same error described up top. I've had Linux Mint 11 and 12 installed on this PC, but was unable to get previous versions of Ubuntu to install (always had errors while installing, not after). Hardware: Intel Core i7-2600K Sandy Bridge 3.4GHz (3.8GHz Turbo Boost) LGA 1155 ASUS SABERTOOTH P67 (REV 3.0) LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 ATX Intel Motherboard EVGA 01G-P3-1371-TR GeForce GTX 460 (Fermi) CORSAIR Vengeance 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Western Digital RE4 WD5003ABYX 500GB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive

• cron+pam heavily spamming my logs

Btw, I've found questions on google but no answers

• RAID 1 in ubuntu 12.04

  - by Bavly Hanna

  Right now I have a small file server to which I have loaded ubuntu 12.04 desktop on a small 160gb harddrive. This harddrive is the primary drive from which the OS boots. I want to move all my data to my file server so it can be shared on the network (contain in 2x2TB harddrives in my desktop. The 2TB drivers are in raid 1 (hardware). I simply want to move them to the file server and set it up so that they are in software raid 1. If at all possible I'd like to be able to do this without losing any info on the drives. I've searched around and the guides i find describe raiding drives for boot driver, but these wouldn't be boot drives just regular storage drives. If someone could tell me how to perform this or point me in the right direction it would be much appreciated.

• How can I run fsck on a disk image via Mac Terminal?

  - by mvizual

  I want to run fsck on a disk image before I use it to restore (replace) a corrupted volume. Using Terminal, what would be the proper command, syntax, and options for this operation? I've just recently become acquainted with Terminal and line commands, so syntax and specific options aren't part of my computing vocabulary. I'm using Terminal 2.1.2, bash, OS 10.6.8. Ultimately, I'm trying to restore an image to a secondary startup volume (external drive). The image is mounted on my desktop and I want to check it for errors before I use it. Disk Utility runs "repair disk" successfully but the integrity of the image is suspect.
