I recently installed Ubuntu on my computer on a separate (internal) hard drive from Windows, and everything works fine except it will not recognize devices plugged into the rear USB ports on my computer. Only the front ones work. I tried looking into power control, and I disabled auto-suspend for all of the USB ports, but it still does not work. When I run  cat /sys/bus/usb/devices/usb*/power/control   it returns everything as "on." I then tried un-plugging my devices, running  tail -f /var/log/syslog   and plugging them back in to see what the error is, and I saw the following errors for each device:  device not accepting address x, error -32 unable to enumerate USB device on port x   When I boot into Windows, I do not have any of these problems, and the keyboard and mouse I have plugged into the rear ports work in the BIOS and on the purple Ubuntu screen that asks which OS to boot. They only stop working once the login screen appears. Please help! Thank you  Edit here are my hardware specifications:   Mouse and keyboard that are not working are stock Dell devices. Ubuntu is running on a 120GB SSD, and Windows is on a 256 GB SSD. CPU is an AMD FX-6300 Motherboard is a Gigabyte GA-970A-DS3P

I am new to Ubuntu. I first downloaded the Ubuntu ISO file and put it in Rufus. Then booted from it in BIOS (MSI Gaming 970) and everything was fine. I've downloaded Ubuntu before, and this time it looked different. there was no Ubuntu logo nor a maroon colored background. I hit "Install Ubuntu" anyways, and came across this:    I let it sit there while I went to school, and came back and it was still there. I realized I should have installed the Nvidia Linux drivers. And so I downloaded them, and don't know actually how to run it (it's a .run file on Windows)  So how am I supposed to install Nvidia graphic drivers for Ubuntu when Ubuntu won't even install?

I'm on an Acer Aspire E5 and I haven't been able to get my laptop's onboard keyboard and trackpad to work, although the trackpad is detected as a Synaptics, and the keyboard is showing as an AT Translated Set 2 keyboard. External mouse and keyboard works fine, and are what I am currently using. I already checked whether I'm on Synaptics or Libinput, although I was fairly certain that upgrade happened a few years ago, and I am definitely using libinput, which I reinstalled, to no avail. I've made sure that the trackpad is enabled in the system settings, and I've switched it from advanced mode to basic in the BIOS, which for some seemed to have been the solution I'd like to note that the onboard keyboard works fine on boot, and its only when X is loaded (i'm assuming) that it fails. I have just recently installed Kubuntu on this machine after grappling with the same issue on Arch, thinking i had done something wrong in the installation. On Arch, I had no trouble using the keyboard on the TTY and live-USB (Arch and Ubuntu), but when i installed X for a GUI, they both stopped working. What should my next steps be?

I've created a bootable USB of Ubuntu 16.04 64-bit with Rufus, setting the drive to be a GPT for UEFI. Then I booted my tablet PC and I ran the UEFI BIOS, from which I turned secure boot off. I then restarted and went again on the BIOS to boot from my key, but all I got was a black screen that lasted few seconds and then it brought me back to the BIOS. I read about a bootia32.efi file and other procedures that can be followed, but I didn't find a good explanation of what I need to get done. My tablet PC runs an Intel Core Atom Z3735F and has 2 GB of RAM. If you have the answer please let me know.

After installing 11.10 on my Dell Studo 15 (Model 1557) laptop, it started to overheat. Recently it even shutdown twice saying that critical temperature has reached even when I was just idling (not even a single program was open except for Firefox). After learning that it is a problem with 3.0.0 kernel I decided to roll back to 10.04 LTS. I have downloaded the most recent   from ubuntu.com and created a live USB using startup disk creator in 11.10.  But when I am trying to boot from USB I am getting the following error  vesamenu.c32: not a COM32R image   I have installed ubuntu from usb stick a couple of dozen times before this and I think it is not a problem with my hardware. Please tell me what to do.

Here's my problem. I'd like to reinstall Ubuntu. My laptop is an old HP Compaq nx7400. The optical drive went wrong, it can't read discs. I would use a USB port instead but the laptop won't boot from it. (It won't boot even if I set USB the first in the boot order in BIOS settings. Also on start up after pressing F9 to choose boot device USB won't appear in the list, only optical disk, netbook disk and network if I enable it.)  I wanted to resize the boot partiton to make space for the installation but I couldn't do that because it seems that the whole HDD is the boot partiton so it can't be unmounted using Gparted.  My partition system is the following:  Disk /dev/sda: 250.1 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders, total 488397168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000e6661     Device Boot      Start         End      Blocks   Id  System /dev/sda1   *        2048   486318079   243158016   83  Linux /dev/sda2       486320126   488396799     1038337    5  Extended /dev/sda5       486320128   488396799     1038336   82  Linux swap / Solaris   So how can I make a new partition to be able to install a "new" Ubuntu and get rid of the old one. Or any better solution for this problem? I hope it's not a catch 22...

My keyboard stops working for no apparent reason.  After using Ubuntu for 2.5 years as a virtual machine on a Windows host () I finally took the plunge, reformatted my hard disk and built the system with Ubuntu yesterday. This morning I my keyboard stopped working.  I see many posts about Ubuntu and a USB keyboard or mouse ceasing to work randomly. They indicate that it is autosuspend turning off power to USB devices to save power, and when the USB device is not compatible in some, the USB does not 'wake-up' as it should.  I tried the suggestion posted in .  But no luck. I also tried another suggestion which was to boot without the keyboard and then plug it in once Ubuntu had started.  Here are some details:   I used the same Kinesis keyboard with Ubuntu as a virtual machine for the past two years, no problem. The Kinesis has macros and triggering a macro triggers the problem 100% of the time. However, it happens when I am just typing (no macros) as well. I tried the Kinesis on a laptop just now. This is a one-year-old  machine that I put Ubuntu 16.04 on two weeks ago. Using a Kinesis keyboard macro did not reproduce the problem.   Problem Machine   Dell XPS, 6 years old, desktop Installed Ubuntu 16.04 yesterday Using Kinesis Advantage USB keyboard Unplugging/re-plugging the keyboard has worked 9 out of 10 times Rebooting works as well I don't think it is a USB power problem as an LED on the keyboard stays lit and other USB devices keep working. I have both a USB and a Bluetooth mouse attached to the machine. Both keep working even when the Kinesis stops. I normally have a second regular Dell branded keyboard plugged in for non-Kinesis folks who need to use my computer. Earlier today this keyboard stopped working each time the Kinesis stopped working. However now, triggering the problem with a macro, the Dell keyboard keeps working.   The Kinesis, which I have had for 8 year now, has made it possible for me to keep keyboarding. If I can't resolve this I'll have to go back to Windows which would be a real bummer.  Any suggestions on things to try or ways to go about debugging this would be greatly appreciated.  I am digging into USB drivers, which on Linux I know nothing about. However, I have found that the laptop has both USB 2.0 and 3.0 ports. The desktop (with the problem) is USB 2.0 only. Still digging...

My usb mouse sleeps after 5 seconds of inactivity when running on battery power. It wakes uo again when i press any button on the mouse. This is really annoying.  I have made lsusb, and I noticed my mouse is   Bus 001 Device 012: ID 04d9:2083 Holtek Semiconductor, Inc.  I have checked my /sys/bus/usb/devices/usb1/power/autosuspend but it is already set to 0, and the directory usb1 has many subdirectories which also have autosuspend files, and i dont know how to edit them.  Also, I would like a permanent solution, which would work for any mouse, on any of my 3 usb ports. Any ideas?  Using: Ubuntu 12.04 64bit

Hardware:  I've got an SSD (c),an internal HDD (d), an external HDD (e) and a USB flash drive (f).   How this all went down:   I downloaded Ubuntu and used a program to install it on my (F) drive. I reset my computer, ran the (F) drive for boot, and installed Ubuntu. I reset my computer, and it forcibly automatically booted into Windows 10 instead of Ubuntu. I went into Windows 10, and used a program called Easy BCD, by NeoSmart. I followed their guide, but after step 6, it wasn't the same for me. Their guide said that upon rebooting, I should see a grub screen that lets me choose between Windows/Linux and a few other options, however my computer would only boot into Windows 10.  I decided to follow the rest of the guide regardless, however by the end it would let me boot 'windows' or 'linux', but the linux option would always break. It went to a screen with lots of commands, that I thought -may- be a barebones Linux or something, but it definitely wasn't Ubuntu.  I decided to reinstall Ubuntu using the USB flash drive. Upon resetting, no matter what hard drive or format I select for booting (besides the F drive), it says An operating system wasn't found. Try disconnecting any drives that don't contain an operating system. I can boot the F drive and run Ubuntu, but it's a one time version that doesn't save any of my data. When I went into the installation, it still says that I already have Ubuntu installed on the 4TB HDD and that I have Windows 10 installed on the SSD, however I cannot seem to boot into either of them.   TLDR: Windows 10/Ubuntu are both installed, Windows on the internal SSD and Ubuntu on the external HDD. Ubuntu's installation program on the (F) drive recognizes them, however, when I try to boot anything it says An operating system wasn't found.   When I press F11 and force it to boot from the SSD it says:  error: no such device: 83b6c64d-9a2c0467b-a02c-6374ee6ac3dc.  error: unknown filesystem. Entering rescue mode. . .  grub rescue&gt; _   and it will allow me to type some commands.

I try to install Ubuntu 16.04 next to Windows 10. Windows is installed on legacy bios and then upgraded to Windows 10. When I try to install Ubuntu from USB stick, it shows a message titled "Force UEFI installation?". It says that the machine's firmware started the installer in UEFI mode but there is an OS installed using BIOS compatibility mode. If I force installation I won't be able to boot Windows.  How can I start the installer in legacy mode?  BIOS of the machine supports legacy and UEFI modes. Legacy support is enabled. But USB disk is always recognized as EFI. USB disk's name is shown as "EFI USB Disk" in BIOS. I cannot change that. I burned the USB with both startup disk creator on ubuntu 14.04 and pendrive software on Windows. Same result.  Thanks.

I am trying to install Ubuntu 14.04 / 15.10 on my Dell XPS 13 9350 (November 2015).  I created a bootable USB disk which boots fine but the installer and the file manager do not detect the hard drive.  What is the problem? How can I solve it?

I'm having a rough time getting Ubuntu to run from a 250 GB USB hard drive.  I booted Ubuntu 9.10 from a CD and ran the regular "install" to the attached USB drive. I used the "advanced" option on the drive partition question to put the boot loader on /dev/sdb (the USB disk) but when I boot the machine it doesn't recognize there's a boot loader on the USB drive (it offers to boot from 2 other devices but not the USB disk).  I also tried booting from the Ubuntu CD and using usb-creator-gtk to set up the USB drive. Seems to me this is meant to work with flash drives. I got a bootable USB disk but it looked and worked like the CD, i.e. it gave me options of "live CD" operation, installing, memtest, etc. That's not the way I want to run the system.  Some help in installing Ubuntu, bootable into a "full" running system on my USB drive would be appreciated.

I got two laptops which share keyboard, mouse and monitor using a kvm-switch. One laptop runs Windows XP and works perfectly. The other one running Windows 7, however does not recognize keyboard and mouse.  I made the hidden devices visible and deleted the unused ones. After the reboot the keyboard and the mouse work. Windows 7 tries to find the 'missing' drivers and upon failing deactivates the devices which renders them unusable again.  Has anybody had the same problem and can help me with it?  Cheers, AC  Edit:  The KVM-Switch is an ATEN Petite CS692 2-Port USB HDMI KVM Switch  The keyboard a standard 102-key Logitech USB  The mouse a Logitech M705 Marathon Mouse with an unify[sic?] connector.  No adapters for the keyboard or mouse but one for dvi to hdmi on the Windows XP machine.

I have a laptop with Ubuntu installed as the only OS. I also have a USB stick with a Windows 7 installation on it. I want to install Windows from the USB stick on my laptop but when I try to restart the laptop to get access to BIOS, I can't seem to find the command for it, its like it skips everything and just says Ubuntu and then takes me to the login screen.  How do I change the boot priority to USB in Ubuntu?

I'm looking to download and install the latest version of Ubuntu to replace the current version of Windows I had pre-installed on my machine when bought it.   I have some really neat features on the machine that I really am hoping will still work when I move over to Ubuntu.  Can someone please confirm if the below will still work and, if not, how I can get them to work:   The USB ports on my machine The ethernet or Network work port on the machine The HDMI output on the machine and finally, the built in webcam   Thanks Sam

I have an Ubuntu 12.04 / Windows 7 dual boot. After installing Ubuntu my computer reboots straight to Windows. There is no option to boot Ubuntu.  Specs:   OS: Windows 7 Home Premium     CPU: Intel i5 2500k     mobo: ASUS P8Z68-V Pro     GPU: GeForce GTX 570      SSD: Corsair 120GB (Windows 7)     HDD: WD 1TB      I select the USB drive in the BIOS and boot to it and choose install. I select to manually configure partitions, partition the 200 GB of unallocated space on my 1 TB HDD into 16 GB swap file, 30 GB / ext4, and 154 GB /home ext4.   I made sure that the bootloader is installed on the Corsair 120GB SSD (where the Windows boot is) and the installation goes smoothly.  When I reboot after the install it runs through the BIOS straight into Windows. I have tried upwards of a dozen times and I have also tried with Linux Mint. I have also redownloaded the ISO and used two different programs to create the live USB.   The installation seems to have gone well, as after the installation I can see the partitions I have created in Windows Device Manager.       I currently run Lubuntu on my laptop, but it is not a dual boot. I'm assuming this is a bootloader issue and I am assuming that inside those partitioned files in my screenshot there is a working Ubuntu 12.04. I just have no way of getting to it.    Update: (copied from comment)  I booted using my Ubuntu live USB and used the Boot-Repair tool suggested in .   Upon opening the tool I saw that it was recognizing my SSD as a removable drive and defaulting to install on the HDD. Once I realized that I was able to force install onto the SSD. My computer can now boot Ubuntu.

I've had the Logitech Wave MK550 for about two years now, and it has acted up twice on me now.  Now being the second time, anyways. What is happening is the mouse and keyboard simply stop working on my computer, however, they work on the same computer on Arch linux, Ubuntu, on my laptop running Windows 7, Arch and Ubuntu as well.   I talked to Logitech tech support today, but that didn't go anywhere. We determined that Windows is finding the devices and installing the drivers appropriately, because they show up in the Device Manager. My PS/2 Keyboard works fine, along with another USB mouse that I am using in the meantime, so she really had no idea where to direct me.  Anyone have an idea as to where to go from here? I miss my keyboard
