• Debian crashed, file system is read-only and cannot backup - How Do I find/mount a USB drive?

  - by Spiros

  We have a Debian server (vm's) here at work and the server crashed after a power failure. I can only boot the system in maintenance mode, and the whole file system is set to read only. I can run fsck though maintenance mode, however I would like to get a backup of some files before I do. Problem: I cannot access the net since there is no network connectivity in maintenance mode, and for some reason I try to add a USB flash drive to the computer but I can't find it through the console. Question: how to you find/mount a usb drive on Debian? I have tried several resources from the internet but nothing worked. Is there any other way I could get a backup of my files? I cannot start networking since the filesystem is set to read only. Any help would be appreciated.

• Windows 7 does not 'wake up' from Sleep mode

  - by the watchmaker

  I'm new to Windows 7, so I don't know if this is normal. When the computer is idle for 30 minutes, the screen goes black and no key pressing or mouse movement will bring the computer out of standby. The computer is still running (fans and hard drive noise) but it will not respond and the screen remains black. The only way to get a response is to press and hold the power button until it goes off, then switch it back on. When it turns on it says "Resuming Windows" and then goes black again. Is this normal? Can the time-out delay be increased? Is there a better workaround than switching the PC on and off?

• oracle virtualbox doesn't work for host Kubuntu since Lucid Lynx 10.04

  - by 13east

  I have a thinkpad edge 14 core i3 2.4 ghz and 4g ram; I have tried kubuntu 10.04, 10.10, 11.10, 12.04 and 12.10 (all x64 architecture); Both oracle and ose virtualbox only works properly to install XP and windows 7 quest system on kubuntu 10.04; For every other kubuntu release since, the guest installation goes as far as formatting the virtual drive, freezes at this step, and doesn't even go as far as copying files to hard-drive to begin installation. But virtualbox has not stopped responding to commands; I can kill that one specific window with the problem installation ("machine" - "close" - "power off the machine") and start over again without having to force-kill virtualbox application. If anyone knows how I can go about addressing this problem, any help you can provide would be very much appreciated. Thank You.

• Little server for a little network: Asus TS Mini + Windows Home Server or other?

  - by microspino

  Hello, I'm building a little network with 4 computer a plotter, 3 printers an a HP Fax/Scan/Copy/Print machine. The network is connected to the web by a D-Link router/firewall. I would like to add little server to have file sharing (reachable via VPN from outside by a single user-road-warrior), automatic backups. I would like to avoid big electrics bills or, to say It in a green way, I would like to avoid useless power consumption made by a big server with hot-plug, Raid, double PSU because I don't need all this stuff. The server must work 24/7 and the budget is between 400€ and 1000€. I'm evaluating the Asus EEE Box (with XP), a TranquilPC (with XP), a FitPC (again with XP), and an Asus TS Mini (with Windows Home Server). I like the latter but since I'm Europe I don't know where I can buy It. Do you have any suggestion/experience to share with me about: which hardware do I have to buy ? which O.S. ?

• Force shutdown a pc stuck in updating via Team Viewer

  - by Martheen Cahya Paulo

  Before I left office, I shutdown my work computer, leaving it in "Please do not power off..." screen. Now, when I log on to my own computer, I saw in Team Viewer that it's on. I thought it restarted instead of shutting down, but when I connect to it, it's still stuck in the previous screen. I've tried sending Ctrl-Alt-Del, but it seems to ignore it. I could still change its resolution via Team Viewer, and the fact that it respond my connection means it's not completely stalled. Is there anyway to shutdown it via Team Viewer?

• Where can I find more information on "Kinds of Information Systems" [on hold]

  - by arielnmz

  Disclaimer: This is not a Power User question, but rather more of the Computer Enthusiasts kind. Also, I don't know the right site to post this kind of question. I'm writing a paper in which I am asked to mention and describe "5 types of information systems" to which my teacher explained: Like Web, Mobile, etc…, for example… He also said that we're not able to mention and describe those mentioned above. So the question is: What is the right topic to research or look into for more information about these different types of "information systems"?

• Windows 8 taking 4+ mins to shutdown

  - by arnab321

  I did a fresh installation of Windows 8 64 bit, build 9200 (released on aug 16th). I installed the drivers and some basic softwares like NetBeans, mingw, iis server and php. For the first few times, it was restarting normally. But then at shutdown, it would show the shutdown screen for some seconds and then turn black for about 4 mins (similar to what happens at hibernation). I disabled the "fast startup" option in power options, but the problem still persists. Windows 7 and Ubuntu shut down normally. specs: 4gb ram, 750 gb sata hdd, solved by installing Windows Updates released during October. It was a serious bug in the OS, afaik. Now even hibernate takes upto 30 secs max. Still, win 8 is too buggy for release.

• Are there any 17-20 inch monitors that support displayport?

  - by WildJoe

  I've got dual monitors now (both 20 inch 1600x1200). After seeing the new eyefinity cards out there (and reading the CodingHorror post on three monitors) I've decided to get a third. It's time to upgrade my video card anyway. Since I don't already have a third monitor and will be buying one new, I figure it'd make sense to buy one that already had a DisplayPort interface so as to avoid the adapter issue. However, I can't seem to find any monitors on newegg that support this (it's not even an option in the power search, and a keyword search turned up only adapters and video cards). A quick google showed me several 30 inchers (like Dell's, but that's way too expensive, and I don't have that much room on my desk even if I had that money) and some 22 inch models. Again, I'm looking for a 17-20 inch with a DisplayPort interface built in. Any suggestions?

• Tabbed terminal that connects to a GNU Screen session?

  - by screenuser

  I use the session feature of screen extensively. For example, I'll start a screen session for "project1" as "screen -S project1", and then when I need to reconnect I use "screen -d -r project1". This makes it easy to manage multiple projects, each with their own set of shell sessions. What I would love to do now is that when running on Windows and Linux, to be able to use a tabbed terminal program (such as gnome-terminal) to connect to a screen session and have all of the screen windows split out to separate tabs. This way I get all the usual power of screen, but with the convenience of a richer GUI experience. Is there any such terminal program available on Windows and/or Linux?

• using one disk as cache for others

  - by HugoRune

  Hi Given a PC with several hard drives: Is it possible to use one fast disk as a giant file cache? I.e. automatically copying frequently accessed data to that one disk, and transparently redirecting reads and writes to that disk, so that other drives would only have be accessed occassionally. (writes would have to be forwarded to the other disks after a while of course) Advantages: the other drives could be powered down most of the time; reducing power, heat, noise speed of the other drives would not matter much. cache disk could be solid state. How can I set such a system up? What OS supports these options? Is this possible at all using Windows or Linux?

• Black screen on Windows 7 right after opening Google Sketchup or Minecraft

  - by Aero

  I get a black screen on Windows 7 right after opening Google Sketchup or Minecraft. I presume there are other applications that cause this too - but I have not tried to open them. The window initially stops responding for a few seconds, before I get a black screen and my Skype call ends abruptly. I have tried waiting for a few minutes but nothing happens. I have to power down my computer and then boot it up again. This is becoming an annoyance, and I don't know what's causing it. Here are my specs, if it helps: My graphics card is an ATI RADEON XPRESS 1100. If you need any more info or if I've missed anything please ask. Thanks :-)

• Benefits of a RAID BBU in addition to a double UPS + PS system

  - by Wikser

  Today I roughly measured the benefits of enabling write-back on the RAID controller on a server at work. It got no RAID battery-backup-unit (BBU) so the write-cache is currently disabled. As the server is not used to capacity (by far), the results in most test were spectacular, e.g.: Database CRUD: before 35s, after 4s Saving a 1MB Excel file: before: 20s (!), after: 0.5s Of course having a BBU is always recommended, but what are the main benefits of installing a BBU to a system, which got redundant power supplies and is attached to UPSs? Does this depend on the type of the system (database, file, terminal)? What is a realistic fail scenario which could be prevented by a BBU? Thanks in advance!

• Difference between “system-on-chip” and “CPU”

  - by Tim

  Very confused, in some websites, they have this line: iPhone 5s CPU: Apple A7 other websites saying that: iPhone 5s System-on-chip: Apple 7 CPU: 1.3 GHz 64bit dual core other sources saying that iPhone 5s System-on-chip: Apple 7 CPU: 1.3 GHz 64bit dual core Apple 7 In Wikipedia, it said: The Apple A7 is a 64-bit system on a chip (SoC) designed by Apple Inc. It first appeared in the iPhone 5S, which was introduced on September 10, 2013. Apple states that it is up to twice as fast and has up to twice the graphics power compared to its predecessor, the Apple A6. While not the first 64-bit ARM CPU, it is the first to ship in a consumer smartphone or tablet computer. There are 2 sentences: The Apple A7 is a 64-bit system on a chip (SoC) and While not the first 64-bit ARM CPU Wikipedia also said “The A7 features an Apple-designed 64-bit 1.3–1.4 GHz ARMv8-A dual-core CPU, called Cyclone”. So System on chip is also CPU? very confused

• Windows: Should I install Server or stick with regular?

  - by stalker92

  I hope somebody can help me solve my dilemma. I have my home PC (using Windows 7) which I use for both work and leisure (gaming, surfing, movies etc.) I tend to never turn it off, only when I must reboot because some installation requires me to or when the power gets lost. But, sometimes Windows starts acting weird (usually after the long period of system uptime), per example eats up randomly all the space on my system partition etc. which is solved after the reset by itself. I was thinking to switch to Windows Server, I guess that it is more optimized for long uptime, well, obviously it is meant for use on servers. Can somebody with more experience with this help me decide is it worth it, will it solve these issues connected with long uptime periods? Thanks in advance.

• View changelog of all packages to be upgraded before upgrading

  - by Stein G. Strindhaug

  When using synaptic on my Ubuntu desktop computer i can review all changelog of all the packages to be upgraded, and unselect a package for upgrade if I want. On my desktop I usually install everything, but I like to at least review what the changes are so that I can delay the upgrade if I suspect it could cause problems with the development tools I use. On a server (Ubuntu Server) with no x-server how can I do the same thing on the console: list all packages that will be updated (apt-get --dry-run upgrade does this along with a lot of noisy simulated install messages), view the changelog (if any) from last upgrade to the version it will be upgraded to. select which packages I want to ignore, or which I want to upgrade I've searched a lot for this but I haven't found anything, possibly I'm not using the correct terminology; but surely this must be possible. Synaptic must get it's info from some some low-level tool I assume? Complicated shellscripts are welcome too, if this is not already easily done with the existing tools.

• When I plug an HDMI cable into my MacBook Pro with Retina Display, the resolution of the retina display changes

  - by Tyler Crompton

  I had an HDMI cable plugged in for a while that connected to a TV with no power. The retina display randomly flashed blue after a while and then changed to a different resolution (possibly 1080p). I unplugged the HDMI cable and nothing happened. So I restarted the computer to no avail. I was still having issues. So I fiddle with some settings after plugging in the HDMI cable again. Now, the retina display appears fine when no HDMI cable is plugged in, but when there is one plugged in, the resolution changes. I have mirroring turned off (which is what I want). The resolution of the retina display when an HDMI cable is plugged in is 3,360px x 2,100px (according to the size of a screenshot) and the external display is 1,600px is 900px. How can I fix the retina display to show with the correct resolution.

• Why is my wireless so slow compared to my wired download speed?

  - by Shawn

  I just used speedtest.net (using Firefox) to compare my wired connection speed with my wireless connection speed. With my current contract (with Videotron), I'm supposed to get Download speed: 8Mbps Upload speed: 1Mbps Here are the results of the speedtest.net test: Wired Ping: 14ms Download speed: 8.41Mbps Upload speed: 1.04Mbps Wireless Ping: 16ms Download speed: 0.18Mbps Upload speed: 0.98Mbps The difference in download speeds seems staggering to me since I did the test 1 meter aways from my router. Any clue as to why my wireless download speed is so low compared to my wired download speed? using Ubuntu 11.04 on an Acer Aspire 5536-5519 Oh and it might be worth mentioning that my girlfriend has no trouble at all with her wireless connection. No slowness at all. (She uses Firefox on Windows 7 on a Dell) Here's the results for the same test on her system: Ping: 22ms Download speed; 8.44Mbps Upload speed: 1.02Mbps

• Video has become blurred and smoothed out?!

  - by benwebdev

  Hi, Since yesterday video and graphics on my Windows 7 desktop seem to have become smoothed out and blurred slightly and I'm not sure why. The last thing I did on the machine was play Fallout New Vegas for the first time. An example can be seen in the picture here screenshot - note how smoothed out the character on the right seems, lots of definition looks lost. It's really annoying and happening regardless of what I watch.

• video card for only watching videos

  - by Nothing 2 Lose

  I recently quit gaming so I took out my (GeForce GTX 550 Ti) video card and switched back to the (cheap) integrated card because I don't want the dedicated card using up power & making unnecessary heat/noise. But now I get lag when I watch high-res movies, or when I open several videos at the same time, but I don't want to go back to my (big/expensive) video card because that seems like overkill. What is the smallest/cheapest card which will only be good enough for watching videos without lagging ? (but not for gaming) PS. My CPU is: AMD Phenom 9850 Quad-Core Processor

• Configuring bridged network connection --- Windows 7 host, Ubuntu 10.04 guest --- VMWare Workstation 8

  - by H3br3wHamm3r81

  Here is my IPCONFIG /ALL from the host (Windows 7 64-bit): Here is my IFCONFIG from the guest (Ubuntu 10.04): To be honest, I don't have experience configuring a network between a host and a guest in VMWare (a virtual machine). I've searched high and low on the internet, but I haven't seen anything that can help. Perhaps I'm just not using the right keywords when I search. Nevertheless, does anyone here have any experience with establishing a network connection? Edit: One important note. I don't use DHCP to provide private addresses to the hosts on my LAN. I use "static" IP addresses on my internal network by configuring each IP address manually in the host's network configuration utility (I have TV's, XBOX 360, and a few PC's). I would like to configure the IP on the virtual machine guest manually as well. The reason is because my XBOX 360 only works properly using a static IP address. It will kick me off XBOX Live if it has one given by the router (via DHCP).

• Network card dies when trying to wake up laptop from sleep

  - by Bugmaster

  I have a Dell XPS 1640 laptop (aka Dell Studio XPS 16), running Vista. Whenever the laptop wakes up from sleep, my Broadcomm LAN card immediately dies. Any attempt to access it completely locks up whichever program I use to access it. There appears to be no way to re-awaken the card, other than rebooting; note that Vista does not even shut down properly if some program is waiting for the card. So far, I have tried the following: Disabled the "allow your computer to shut down this device to save power" in the device properties. This had no effect. Attempted to disable and then enable the card in the device properties. No effect. Tried ipconfig /renew: this locks up ipconfig to the point where I can't even kill its process. Force-install updated drivers from broadcomm: no effect. Does anyone have any other ideas ?

• EXT4 external hard drive for use with multiple systems

  - by EXTdumb

  I recently bought a external hard drive to store some data on. I use Linux but I am not a power user. If I format the drive to EXT4, is it possible for the permissions to ever screw up and I lost access to my data? I will be plugging the drive into several different linux based computers at work and I frequently hop distros on my main home machine. I need to make sure I don't lose any data because I overlooked something. I am not familiar with EXT 3 or 4. So far I have done this : Formatted drive to EXT4 ran gksudo thunar and changed the permissions to my user account and all settings to read/write Wrote all the files I need to the drive I really appreciate any help.
