  • In 10.10, USB 3.0 PCI Express card recognized by lspci but not lsusb or dmesg. How to fix?

    - by Paul
    Asus N PC, runs 10.10 x86_64 The Asus N comes with 4 usb 2.0 ports, each labelled 2.0 on the case. Attempting to add two usb 3.0 ports to be provided by a generic usb 3.0 pci express card installed in the pci expres slot. The new card says usb 3.0 and has the blue ports. The card is installed into the laptop unpowered, then the laptop is powered on and boots normally. Nothing happens when a USB 3.0 flash drive is inserted into the usb 3.0 port. uname -a Linux drpaulbrewer-N90SV 2.6.35.8 #1 SMP Fri Jan 14 15:54:11 EST 2011 x86_64 GNU/Linux lspci -v 00:00.0 Host bridge: Silicon Integrated Systems [SiS] 671MX Subsystem: ASUSTeK Computer Inc.

  • Creating a bootable flash without overlayfs

    - by Septagram
    I want to create an USB stick to carry my Ubuntu everywhere around with me. It's not intended to spread Ubuntu by installing it everywhere, but rather for running my configured system on any computer I come across. So far, I went with installing Ubuntu with unetbootin, however, I have some issues with this. When installed with netbootin, the original disk image is kept intact on the flash drive, forever. Also, a file is created for persistent storage and during boot it is accessed together with the image by overlayfs. This, in my opinion, has the following problems: If system is updated regularly, then files from the image are overwritten in persistent storage, doubling their size and wasting precious space. Persistent storage has a fixed size that you have to define from the start, again, wasting precious space. I'm not 100% sure, but maybe using overlayfs makes disk access slower, and more so on the relatively slow devices. So I'd like to find another solution: either to get rid of the original image or to install Ubuntu "normally" on the separate ext2 partition, or maybe even install it in the main vfat partition on the USB stick. Suggestions?

  • Getting file system free space

    - by Fred Riley
    This isn't a problem as such, more a request for information based on ignorance of the Linux filesystem. The very short question is: How do I find out how much free and used space there is on the volume from which Ubuntu is running? More detail: I'm running Ubuntu 12.04 from a 64Gb USB3 stick, created from booting up a year-old Ubuntu 12.04 DVD and running Startup Disk Creator. The reason for this is that the Master Boot Record on my hard disk, holding Windoze 7, has gone belly-up, and whilst awaiting a recovery disk I'm running Ubunto off USB or DVD as a 'trial'. (And will continue to run Ubuntu after restoring Windoze, as I've rediscovered my love of the penguin :o)) After installing Ubuntu on the stick I ran the software update app, which downloaded some 450Mb of updates and took a couple of hours to install to the stick. A couple of times I got a message saying that disk space was short. So I looked in the file manager (or whatever it's called these days) and couldn't see the stick listed, just: SYSTEM hard disk (listed as 479Gb Filesystem) two other partitions that had been created by Windoze "4.3GB Filesystem" which when I try to open gives the error "Could not find /cow", and when I try to unmount it tells me I can't because it's not mounted - D'OH!! Edit: screenshot of file manager Edit: screenshot of low disk space warning What I can't see is the USB stick from which I'm running Ubuntu. Where's it gone, anybody know? This is tangentially related to a previous question of mine about system tools, in that I'm trying to get control and knowledge of the system in the newest incarnation of Ubuntu.

  • Change Keybindings (hardware to software)

    - by Daniel
    I ran a search for this, but the answers I saw were referring to something altogether different than what I'm asking for. So let me clarify: I'm not asking how to change key-combo shortcuts. I'm asking--how do you actually change what your computer thinks you did when you press a given key? An example of what I mean (and the reason I'm asking). I'm a Chrome user, and I use Windows alongside Ubuntu. I own a Lenovo Thinkpad T61p--it came with my scholarship package, and I would have shopped for a nice computer if I could have. The T61p has two buttons above the left and right arrow keys that relate to browser commands to go back and forth one page. This is extremely frustrating for me, as I use the arrow keys, and a single accidental keystroke will catch me going back a page, losing temporary data, and yelling at my stupid keyboard. At the same time, I'm the type of person who keeps way too many tabs open. Chrome doesn't let me refigure keyboard shortcuts, and the only way it allows you to switch between tabs are ctrl+tab and ctrl+shift+tab, and ctrl+page up/down. I was using Notepad++, and they had finally found the solution to both problems! The page back and forth keys functioned as tab back and forth keys. I went through quite some effort to learn how to change the keybindings in Windows. The page back and page forward keys are now the page up and page down keys, respectively, and if I hit control, they let me switch tabs easily, and rather pleasantly. And if I hit the keys by accident, no harm, no foul. Alas, I'm in Ubuntu now, and I need to go through the process again. And while I couldn't just find the answer online, like I did for Windows, I know Ubuntu has nice, supportive communities like this one, where, hopefully, somebody can tell me how to do either what I did in Windows, or directly make it so that my computer changes tabs when I hit those buttons (removing the ctrl button from the tab-changing command).

  • Why doesn’t windows explorer show my removable / USB drive even though the command prompt does?

    - by Gishu
    I'm running WinXP SP2. Around 50% of the time, when I slot in my USB drive. Windows explorer refuses to show the drive. If I click on the Safely remove hardware icon on the tray, I can see a menu item for the drive - say drive G: (the light on the USB drive is also on) If I type in G: into the address bar of explorer, it says 'Cannot find...' If I type in G: into a command prompt window, it works and I can do a dir to see the list of directories on the drive. To fix this, I've to remove-reinsert the pen-drive. But doing it every day is annoying. Also this happens only on this machine.. I use this drive on my home machine and it works flawlessly each time. Can anyone suggest things that I could try ? Thanks for reading...

  • How to fix corrupted filesystem (shows as RAW) in USB device?

    - by Erico Yan
    I would like to ask if you know how to fix a corrupted USB? I've tried the diskpart command but it didn't work. The media is write protected. Do you have any idea that is much better? I need to fix it because I have important files in my flash drive. I really need to retrieve it. I saw that the file system is seen as RAW and is unaccessible. I tried error checking, but it requires you to format it. I tried data recovery software but all files come out corrupted. My USB is Imation 4GB. Any suggestions?

  • How do you install a USB CD Rom drive?

    - by Matt Allen
    Hello, I recently purchased a USB CD ROM drive, but I don't know how to get it to work with my computer which runs Ubuntu 10.04. http://www.amazon.com/gp/product/B00303H908/ref=oss_product When I issue the lsusb command, it shows up as: Bus 002 Device 016: ID 05e3:0701 Genesys Logic, Inc. USB 2.0 IDE Adapter The computer doesn't recognize it automatically. How can I get this drive to show up as an actual drive on my computer? If this particular drive can't handle Linux, can you recommended one which can and provide a link to it so I can purchase it? Thanks!

  • Microsoft Mouse and Keyboard Center Needed for Keyboard but Doesn't Support Mouse

    - by eljay
    I recently built a new computer (running Win7 Pro 64-bit) that includes the Microsoft Sidewinder X4 Keyboard. To make use of all the extra features of this keyboard I need the Mouse and Keyboard Center. I just ran Windows Update for the first time on this system and the Mouse and Keyboard Center was included in the update. I'm left-handed and before the update I had the mouse set up for lefty use. Now after the update, it's been set to righty use and the original mouse control panel applet no longer allows the assignment of buttons. For that there's a link to the Mouse and Keyboard Center which does not support my oldish mice. (I have an IntelliMouse Optical and a Creative Mouse Lite Pro.) So I need the new utility for my keyboard, but I have to be right-handed to use my mouse? Really! I tried changing HKCU\Control Panel\Mouse\SwapMouseButtons to 1, but a reboot set it back to 0. Is there some way I can change my mouse back to left-handed? Thanx -eljay

  • What is the best keyboard for typing speed (not layouts)

    - by Gapton
    So I am a programmer, and I like playing typing speed games. My typing speed is, for common English words, 85 to 90 wpm, max 95. I type on various devices, my laptop, desktop, office pc.... they all have slightly different keyboards. Being a curious programmer, I wonder what types of keyboard is used for the highest possible typing speed. Or let me phrase it in another way, what is the type of keyboards that people use in typing speed contest? Here is something I know that I feel like I can share: It must be a wired keyboard, I can feel the lag as I am typing this on my wireless keyboard, even if it is a slightly more expensive model which claims to have zero lag. I know people prefer a mechanical keyboard, for the hepatic feedback, however I have not tried one. It lasts longer and is noisy, it also does not have the problem of normal keyboards where you press many keys at a time the signals will get all jammed and the computer will only receive one or two keys. I personally prefer those "thin profile" keyboards. I type a lot, and 95 wpm put me in the top 5%, this is of course just on a gaming site. However when I type on the fat keyboards, my fingers have to travel a much longer distance before the keys actually click. This is where I find myself typing much faster with those thin profile keyboards found on my laptop. Because my fingers only hover on the keys and I only need to press a short distance, each stroke takes less force and light rapid strokes is what makes me type fast. When I type on a fat keyboard, I was forced to use heavy strokes, and this slows me down. There must be some people out there who are keyboard scientists, who actually do experiments and user tests with different setups. It would be interesting to understand more about the things we use everyday for not just work but a majority of our communications. P.S. this is about hardware and not about switching keyboard layouts to dvorak

  • Google Chrome mouse wheel takes keyboard focus

    - by Steve Crane
    I recently switched the default browser on all my machines from Firefox to Google Chrome. In general I’m loving Chrome but there is one behaviour that is driving me nuts. Scrolling with the mouse wheel takes keyboard focus away from the document. Here’s what happens. I’ve just opened a page or switched to a new tab and the page has keyboard focus as I can use the keyboard up/down and PgUp/PgDn keys to scroll it; no problem there. But if I then use the wheel on my mouse to scroll the page, it loses the keyboard focus and no longer responds to up/down, PgUp/PgDn, or in fact any other keyboard keys. I have to click on the page background to restore the keyboard focus. This is a minor inconvenience for scrolling but where it really drives me nuts is in Google Reader and Gmail where I use keyboard shortcuts a lot. Here I find that I scroll the article or e-mail I’m reading with the mouse wheel then get no response when I press j/k to move to the next or previous article or e-mail. I am using Windows 7 and the Chrome dev channel (version 4.0.249.43).

  • New keyboard for linux: Adesso Tru-Form or MS Natural Keyboard 4000?

    - by Andrea
    Hi folks! I'm going to buy a new ergonomic keyboard for my laptop. In the following, keep in mind I live in Italy. I considered the following models: Adesso PCK-308UB - Adesso Tru-Form™ Pro - Contoured Ergonomic Keyboard with TouchPad-PS2 Pro: has a built-in touchpad in the same position of my laptop somewhat cheaper than the alternative below Cons: the surface doesn't seem to be bowl-shaped. keys seem to lay on a straight slightly-inclined surface. It seems an idea used extensively in other ergonomic keyboards according to a few comments on the net, new Adesso keyboards seem to lack robustness, they're likely to loose small parts after a few weeks or months. Other users, instead, seem to never had any problem in years and swear by their quality and comfortability. Those who had problems, however, lamented a lack of responsiveness from the manufacturer. I'm not sure whether the keyboard, at least the standard keys, and the touchpad will both be recognized correctly under linux distros (I mostly use FC btw) last time I checked, Adesso didn't have local resellers in my country Microsoft Natural Ergonomic Keyboard Pro: recognized as one of the most comfortable keyboards reliable customer service operating in my country AFAIK there are several documented ways to get extra buttons work with linux Cons: it doesn't have a builtin touchpad and has a numeric keypad wasting space to reach mouse But there could be other keyboards I haven't considered yet, so here follows my ideal keyboard wishlist, ordered by priority linux compatible basic ergonomic design, which entails split tilted keyboard and pads advanced ergonomic design, like true-ergonomic's or kinesis , where special keys (like enter, caps-lock...) are placed symmetrically in the middle to be used by thumbs a builtin touchpad/trackball placed under the keyboard. I just love this on my notebook. I think it's pretty effective, since it allows my hand to rest naturally everytime I use it. Any opinion on this? high-quality switches, like cherry's (unsure about this one) additional programmable keys placed near usual ones, to simplify typing shortcuts TIA Andrea

  • Windows 7 x64 RTM USB Port Has Power But Won't Recognize Mouse/Keyboard/Anything

    - by ben
    I have an odd error that doesn't seem to fit in with any of the other odd Windows 7 x64 USB errors that have been kicked up on Google. Here we go: Uninstalled Tortoise SVN and clicked restart computer. My machine had been up for around 28 days On reboot my mouse and keyboard failed to work anymore, couldn't log in. Tried every USB port I have on my Dell 390 and the ports on my Dell 19's, nothing worked. They had power but Windows would not respond when I manipulated the keyboard/mouse. Rebooted my computer and pressed F2 to get into bios, my keyboard is working fine in bios. Keyboard and mouse work fine on other computers when using USB. Found adapters for keyboard and mouse to convert from USB to PS/2 ports, works fine. I'm actually typing this question on the same keyboard, same computer, just using PS/2 ports for my mouse and keyboard. It appears to be a Windows 7 x64 issue. Other things I have tried: Multiple other mice and keyboards, iphone, all with no luck. Each one gets power, but Windows never tries to install drivers or sees that they are connected. Uninstall and reinstall all USB drivers. Drives uninstall and reinstall fine and report no errors in Control Panel. In Power Management I disallow Windows from turning off USB ports to save power Installed the latest nVidia drivers for my graphics card, no change. Anyplace else I can look/try? Thanks!

  • Dell PS/2 Keyboard Stops Working Randomly After Power Disturbance

    - by Kenneth Murphy
    I have a Dell PS/2 keyboard connected to a desktop PC running Slackware 12.2 & Windows XP. After a recent, brief power outage/disturbance at my home, the keyboard has begun to quit working at random times. It has stopped at POST, but not by keyboard error -- I have to press the F1 key to continue booting, and at times the keyboard has already stopped working. Other times, the keyboard will work perfectly for a long time (a day or more) before it finally quits. It has stopped at boot, in Windows XP, and in Slackware. The led lights continue to work regardless. I have tried another PS/2 keyboard and it seems to be immune to this problem. The USB mouse always works. Does anyone have any ideas about how this might have happened? If this is related to the power disturbance that killed the power to the running PC, is it feasible that it would have only fried the keyboard itself (which still works sometimes) and not the PS/2 port nor anything else? I have experienced no other problems since the event.

  • Keyboard doesn't function after Fedora 17 update

    - by mickburkejnr
    I updated my Fedora 16 installation to Fedora 17 on Saturday, and the update worked without reporting any errors. I carried on working on the machine in question and then switched the computer off. Last night I went back on the computer, I switched it on and got to the log in screen. At this point I tried to type in my password but the keyboard wouldn't work. I unplugged it (it's a PS/2 keyboard) and plugged it back in. The lights flashed for a split second but the keyboard still wouldn't work. I then plugged the keybaord in to a USB to PS/2 adapter, and the keyboard still wouldn't work. I restarted the computer and tried to access the BIOS and I was able to do so. So the keyboard doesn't seem to be faulty, it just doesn't work when Fedora boots in to the GUI interface. I did try to boot in to the "recovery mode" of Fedora, and the keyboard works here with no problem. As I still have access to Fedora via a terminal interface, is there anything I can do to fix the keyboard problem via the terminal without having to reinstall Fedora?

  • Seagate 3TB ST3000DM001 hard drive not recognized by Linux, causes fdisk to hang

    - by MountainX
    I'm running Kubuntu 12.04. I have a brand new, never used Seagate 3TB ST3000DM001 hard drive. It's an internal drive. I installed it in a USB enclosure. When I connect it to my PC, nothing happens automatically. When I run sudo fdisk -l, fdisk hangs (without reporting this drive) until I disconnect this drive from the USB port. blkid won't report it either. I tried connecting it to both USB 2.0 and USB 3.0 ports on my PC. I got the same result either way. I tried two different USB enclosures with the same result. If I take the same drive, same enclosure and connect it to a Windows 7 laptop, it is recognized automatically as a USB mass storage device. I want to format the drive (probably ext4) and copy files to it. I have another drive, also in a USB enclosure, that is connected via USB 3.0 to this PC and it works fine. It's a 2.0 TB Samsung HDD. I plan to copy files from the 2TB to the 3TB drive, once I get this issue resolved. My motherboard is an Asus Asus P8B WS LGA1155/ Intel C206/ Quad CrossFireX/ SATA3&USB3.0/ A&2GbE/ ATX. What is the resolution?

  • How to generate an extended F key press (F13-F20)?

    - by Emilien
    I need to submit an extended function key (like F17 or F17 ) to a program that runs in the terminal (I use the default gnome-terminal but could use another if it works there). Is there a way in Ubuntu 11.04 to generate those key hits? I'm searching for something like Shift+F7 to generate F17 (what I currently use in Reflection under Windows). My keyboard is set to generic 105 keys PC with the US Qwerty layout.

  • Gigabyte GA-970A-UD3 mobo won't boot from USB flash drive

    - by user38586
    I am trying to boot BAMT a Debian flavor via USB on a brand new Gigabyte GA-970A-UD3 motherboard. I tried various flash drive and various OS. I never had this problem with ASUS and MSI. The problem is from Gigabyte hardware. I found that my BIOS is very strict about MBR compatibility. Now I can boot in DOS mode. The flash drive need to be formated as a Win98 Startup disk using HP USB disk storage format tool. Unetbootin menu is booting from USB but won't install BAMT. If I use Windows or Linux diskimager the working MBR is deleted. I tried converting BAMT .img to .iso and it is not booting with Unetbootin. Is it possible to boot BAMT(Debian Linux) from a Win98 DOS command prompt? Maybe there is a way to burn the image and keep the working MBR? If the working MBR is deleted, the flash drive is not recognized at all by the BIOS. This is the info I found that got me booting for the first time in DOS: GB's BIOS will only boot USBs formatted to FAT-32, conforming to normal MBR bootloader. I've seen this before, and surmised that the 'stick-maker' was formatting in ReiserFile, or one of the EXT 'flavors', but no one ever followed up to confirm or deny... Also, if it's putting the bootloader into its own partition - won't work! In the BIOS, on the "Integrated Peripherals" page, the "USB Storage Function" item must be enabled (which should be the default) to allow USB booting... I've put a little work into a 'GB USB booting tutorial', and frankly, I'd just go ahead and finish it up for you, but I really don't want to reboot the several times it will take me to 'firm up' procedural details, and take the BIOS/boot pictures for the post - just noticed VAIL finally went 'public beta', so will be downloading for likely twenty-six hours or so There's likely enough there to test a 'raw DOS boot', just to see if your hardware (especially the USB stick itself) will do it... Some post later: Fixed. Here is a brief summary. Since my ubuntu live usb sticks (2gb kingston and 8gb sandisk sd/usb reader - fat32, created in ubuntu 10.04) would not boot this board even though they would boot my ga-ep45-ud3p, I decided to try bilbat's suggestion with the HP usb boot program. I created the win98 boot disk on the kingston 2gb stick without reformatting. It booted right up. Next, I used windows version of unetbootin to write the ubuntu live cd to the kingston disk. This fired right up and completed the install. Everything seems to be in good order now. Unfortunately I can boot in DOS mode but can't boot BAMT.
