• Laptop in-built Web Cam stopped working HP Probook

  - by Dave A

  My laptop (HP Probook) webcam has always worked. When I upgraded to 13.10 it stopped working. No solution found then so gave up. Recently upgraded to 14.04 still not working so thought I would ask anyone again if a solution had been found. lsusb Bus 001 Device 004: ID 0c45:62c0 Microdia Sonix USB 2.0 Camera dmesg | grep uvcvideo` [ 765.466575] uvcvideo: Found UVC 1.00 device USB 2.0 Camera (0c45:62c0) [ 765.467305] uvcvideo: UVC non compliance - GET_DEF(PROBE) not supported.

• Triggering an action when a specific volume is connected

  - by ereOn

  I have a USB key that contains my keepass2 password database and I'd like to perform some actions when it is plugged into my computer, namely: Auto-mount it to some specific location When the mounting is done properly, launching keepass2 on the password database file Simple tasks I guess, but I can't find how to do that. I'm using Ubuntu 12.10, and it auto-mounts the device as a "media usb-key" and tries to open the images on it (even though there are none). What is the best way to do that and to disable the ubuntu auto-mounting (so it doesn't conflict) ?

• How do I rename a mounted Truecrypt volume?

  - by invert

  When I mount the Truecrypt file on my USB drive it shows up as truecrypt1. The volume is FAT, using mtools to rename a volume label involves e2label /dev/sdbx, however truecrypt1 does not map to a physical partition. fdisk -l does not show the volume partition (only the physical USB device), and df -h lists the volume path as /dev/mapper/truecrypt1. Finally, using the Nautilus 'Rename' context action, gives the error: "Sorry, could not rename "truecrypt1" to "towel": Operation not supported by backend". Apparently this can be done in Win, but how can I rename this volume in Ubuntu? As Nicolas said, specifying the mount point names the partition the same. The truecrypt GUI does not remember the mount point I set, so I specify the mount points in a script which I placed in my main menu. #!/bin/bash gksudo truecrypt /media/usbdrive/encryptedfile /media/securedata/

• Keyboard freezes when xorg crashes

  - by gsedej

  Situation is like that. Many times has happened that Xorg freezes and with it also keyboard. Quite some times because of some Compiz effects or Flash (fullscreen switch). Keyboard becomes totaly unresponsive, while mouse still works (I can move cursor, but can't click since desktop freezes) and music still plays and I can connect trough ssh. This is the only way I know I can try to solve problem - either by killing browser&flash or lastly restarting xorg server. This problem appears on more than one Ubuntu computer. My home dekstop with proprietery nvidia driver, on my work where I use noveau driever (opensource driver for geforce) and sometimes (but rarely) also on laptop with ATI graphics (using r300g driver which is really good!). Can someone explains why mouse still works while I can't input from keyboard? (I can't switch to virtual console or do R-E-I-S-U-B command) I have USB keyboard and USB mouse.

• What does Ubuntu do when I signal undocking to a laptop?

  - by Seppo Erviälä

  It seems that Ubuntu runs some script or command when I signal that I want to undock my laptop by pressing the undock button on the dock. Most visible thing that happens is that resolution on external display is changed. After prepearing for undock my laptop is still connected to power, VGA-output and audio jacks through dock but not to any usb devices or optical drive. I'm running 11.04 on a ThinkPad X61s with X6 UltraBase. What happens when I signal undocking? This is what dmesg says after pressing undock button: [81459.990682] ata1.00: disabled [81459.990727] ata1.00: detaching (SCSI 0:0:0:0) [81459.991722] ACPI: \_SB_.GDCK - undocking [81460.009462] ehci_hcd 0000:00:1a.7: power state changed by ACPI to D0 [81460.020252] ehci_hcd 0000:00:1a.7: BAR 0: set to [mem 0xfe226c00-0xfe226fff] (PCI address [0xfe226c00-0xfe226fff]) [81460.020265] ehci_hcd 0000:00:1a.7: power state changed by ACPI to D0 [81460.020281] ehci_hcd 0000:00:1a.7: restoring config space at offset 0xf (was 0x300, writing 0x30b) [81460.020309] ehci_hcd 0000:00:1a.7: restoring config space at offset 0x1 (was 0x2900000, writing 0x2900102) [81460.020338] ehci_hcd 0000:00:1a.7: PME# disabled [81460.020346] ehci_hcd 0000:00:1a.7: power state changed by ACPI to D0 [81460.020352] ehci_hcd 0000:00:1a.7: power state changed by ACPI to D0 [81460.020363] ehci_hcd 0000:00:1a.7: PCI INT C -> GSI 22 (level, low) -> IRQ 22 [81460.020372] ehci_hcd 0000:00:1a.7: setting latency timer to 64 [81460.020432] ehci_hcd 0000:00:1d.7: power state changed by ACPI to D0 [81460.040071] ehci_hcd 0000:00:1d.7: BAR 0: set to [mem 0xfe227000-0xfe2273ff] (PCI address [0xfe227000-0xfe2273ff]) [81460.040085] ehci_hcd 0000:00:1d.7: power state changed by ACPI to D0 [81460.040104] ehci_hcd 0000:00:1d.7: restoring config space at offset 0xf (was 0x400, writing 0x40b) [81460.040133] ehci_hcd 0000:00:1d.7: restoring config space at offset 0x1 (was 0x2900000, writing 0x2900102) [81460.040170] ehci_hcd 0000:00:1d.7: PME# disabled [81460.040178] ehci_hcd 0000:00:1d.7: power state changed by ACPI to D0 [81460.040184] ehci_hcd 0000:00:1d.7: power state changed by ACPI to D0 [81460.040195] ehci_hcd 0000:00:1d.7: PCI INT D -> GSI 19 (level, low) -> IRQ 19 [81460.040204] ehci_hcd 0000:00:1d.7: setting latency timer to 64 [81460.040503] ehci_hcd 0000:00:1d.7: PCI INT D disabled [81460.040552] ehci_hcd 0000:00:1d.7: PME# enabled [81460.061657] ehci_hcd 0000:00:1d.7: power state changed by ACPI to D3 [81460.200414] usb 1-4: USB disconnect, address 14 [81462.220088] ehci_hcd 0000:00:1a.7: PCI INT C disabled [81462.220169] ehci_hcd 0000:00:1a.7: PME# enabled [81462.240115] ehci_hcd 0000:00:1a.7: power state changed by ACPI to D3

• Installing Ubuntu 12.10 on new computer with Windows 8

  - by rft183

  I recently purchased a new HP computer (P6-2330) with Windows 8. I have tried unsuccessfully to install Ubuntu 12.10 64bit alongside Windows 8. The computer is UEFI with Secure Boot enabled. I've tried following the instruction at https://help.ubuntu.com/community/UEFI. I am able to get the GRUB menu to show up. However, as soon as I press Enter on either Try Ubuntu or Install Ubuntu, the screen goes blank. Nothing works at all, not even the Num Lock or Caps Lock keys on the keyboard. I have to use the power button to restart the computer. Does anyone have any suggestions on how to get Ubuntu installed? To clarify, I have actually tried installing using both a USB stick and a DVD. The USB stick gave a blank screen, while the DVD gave the error message "Empty Security Header" after pressing Enter at the GRUB screen.

• Keyboard and touchpad do not work

  - by user289219

  I have an Lenovo IdeaPad S210 Touch and I want to install Ubuntu on it. The problem is that when I try booting the system from a USB drive (starting the so-called Live session) to try to see if the system works on my computer, the system will turn on and everything will work properly except for the keyboard and the touchpad. Neither of them are listed when using this command: xinput --list. I cannot get my laptop keyboard/touchpad to work, but USB keyboards and mice will work and my laptop's touchscreen will also work.

  - by stanleyhunk

  I'm new to Ubuntu, I bought an Asus A45VS laptop recently pre-installed with Windows 8, but I have already uninstalled it and wipef the whole HDD. I plan to install Ubuntu 13.04 64 bit on it. I have tried several times to install and uninstall Ubuntu again and again with boot-able USB, but it still fail to boot. All the installation process go fine, after rebooting my laptop, it just stick to the purple screen. Then I boot it with USB again, tried boot-repair, tried make an EFI partition, still the same. I have searched on the web, and all of them was about dual booting with windows 7 or windows 8, I don't wish to do dual booting as I wish to have single OS which is Ubuntu on this laptop. please help, thanks in advance.

• I'm getting a black screen right after Install Ubuntu option on GRUB menu. Any ideas?

  - by Silight

  I've formatted my USB and remade the live USB twice. I tried editing editing the commands (pressing the 'e' key while the command was highlighted on the GRUB menu) by 1. deleting quiet splash and replacing it with nomodeset 2. adding nomodeset right before quiet splash 3. deleting quiet splash and adding radeon.modeset=0 I saw another solution for a fix by editing GRUB but in command line 'sudo' 'nano' and 'update-grub' all show up as unknown commands. I'm brand new to Ubuntu, in case you couldn't tell. I would appreciate any help you could give me. I want to convince my brother that Ubuntu is a better option than iOS but I can't do that if I can't install it. If you need more information, please ask. I'm not dual booting. I want this to be a full install. Thanks.

• Configuring Dropbox on Ubuntu server

  - by Daniel

  I've got a Ubuntu server running on an old laptop. The OS is on a 4GB USB drive and I use a SATA drive attached for storage. Now I wanted to set up Dropbox on this machine. I've got it running using this guide: http://www.byteindia.com/internet/install-dropbox-on-linux/482/. But I haven't synched yet because there won't be enough room in my home dir. My /home is on my 4GB USB since I never use it and all my data is on the 2TB drive mounted in /media/. What is the best way to set this up? Dropbox doesn't support moving the folder in Linux yet. I found a script to move the folder but it seems outdated. Perhaps I can use symlinks in some clever way? Or maybe move my /home folder to my SATA drive? Thanks in advance

• 12.04 in Virtualbox is keep losing my wireless connection

  - by Derek

  I've Windows 7 as the Host OS, Ubuntu 12.04 as the guest and a Netgear WG111v2 as the USB Wireless device. Its connected to an open Wi-Fi network at work to bypass my works crazy strict filtering, When on the domain. I currently have network eth0 turned off in the virtualbox settings so the only network source would be through the USB device at wlan1. Its odd but the wireless seems extremely temperamental, I constantly have to ifconfig wlan down then ifconfig wlan1 up to get it back online. I know this might be super vague just curious if anyone has tried something like this or run into anything like it to point me in a direction I might not be seeing.

• How do I get my RTL8192ce based wireless device working properly?

  - by JonnyTruelove

  I am using the rtl8192cu chipset (on a Belkin wireless USB adapter N300) combined with 64 bit architecture and the 3.8 kernel. Some of you may know that this doesn't work. I tried this fix - RTL8188CU USB Network Adaptor on ubuntu 13.04 and now my internet is super slow. I am totally new to Ubuntu and I am concerned I do not have the right driver. The "stock" driver was the RTL8192cu, but it didn't connect 99% of the time and if it did the upload speed was higher than the download. Right now I am connecting through my laptop with a crossover cable, so my internet connection is just fine in my apartment. Relevant output from lsusb is here: Bus 002 Device 002: ID 050d:2103 Belkin Components F7D2102 802.11n N300 Micro Wireless Adapter v3000 [Realtek RTL8192CU] (bonus question: is that [050d:2103] the actual physical address straight from the hardware? Or does it change when I put different drivers on it? I am concerned I do not have the right driver)

• Windows Phone 8 detected as mass storage

  - by legends2k

  From version 8 onwards Windows Phone supports MTP (media transfer protocol) to transfer audio and I thought I could use Rhythmbox to upload music onto my device. Thing is Rhythmbox doesn't display the device under Devices pane (there's no Device pane for that matter). I searched other questions here and tried out installing mtp-tools, mtpfs and also tried gMTP, which doesn't seem to detect the device as a portable player. I see that the device's icon looks like a Camera in dash bar and when I see the address location, it shows gphoto2://[usb:002,013]/, which makes me doubt that it's detected as a camera or as a mass storage device. /.gvfs/gphoto2 mount on usb%3A002,003 is where the actual mount is. What do I do to fix this? I tried creating .is_audio_player too.

• What to use for "localhost" that includes PHP/SQL functionality?

  - by Jack

  I really do not want to install Linux at the moment, I would have to borrow a USB key, move files, format it, flash it, format it again, move files back, give it back... What would you recommend that is lightweight, easily and cleanly uninstallable afterwards (will install Linux when I get a new DVD-ROM, which will be in ~2 weeks), that also supports PHP and SQL? To be precise, I want to install a Wordpress blog, a few plugins, etc, and develop a theme. If there is no such thing for Windows (7, x64 if that matters), let me know too, I will borrow the USB key then (even though it's a pain).

  - by Chris Hoffman

  When burning a CD or DVD with Windows, you’ll be asked whether you want to use a Live File System or a Mastered disc format. Each has its own advantages and disadvantages. Windows 7 refers to this as “Like a USB flash drive” or “With a CD/DVD player.” But how exactly can a non-rewritable disc function like a USB flash drive?

• Mouse cursor lag after lock screen, 64 bit 12.04

  - by Bill Jones

  Recently I have noticed that when I return to my computer after it has been "locked" for a while, the mouse pointer has significant lag. The cursor position appears to only update a few times a second. Moving the mouse results in the pointer "following" the movement in a jerky kind of way, and then continuing for some fraction of a second after I have stopped using the mouse. Replacing the mouse has no effect. (I have two differently branded and constructed usb optical mice). Plugging either mouse into a different usb port has no effect. Once the problem was resolved by "suspending" the system, and then re-starting it with the power switch, but this does not work every time. So far, the only fool-proof fix is to shut the system down and re-start it (re-boot). I have tried this suggested fix. It had no effect.

• Problem with keyboard and trackpad on ubuntu 12.04

  - by Cdub

  Have a really strange issue with my keyboard and trackpad after installing ubuntu 12.04. It picked up both fine with the livecd and in the install, but for quite awhile now, I find when I power my laptop up (Toshiba Satellite L775D-S7132), when I hit the login screen much of the time I won't have any keyboard or touchpad. I can plug in a usb mouse and then at least restart or shut the laptop down and then keep trying until it picks it up correctly, but it's really a pain to have to do that all the time. Are there quite a few bugs related to keyboard and trackpad issues with the new version? I really want to get this issue resolved as it's a major nuisance. Otherwise, my hardware gets picked up fine. Video, audio, wlan, usb work perfectly and I don't ever have any issues with them. What's the best way to figure out the problem? Thanks in advance, C.

• Dual booting windows 8/ubuntu 12.04.2, Grub doesn't appear and machine never boot in ubuntu

  - by black sensei

  i got a new ACER predator AG3620-UR308 which came with windows 8, so i wanted to run ubuntu 12.04.2 on it as a dual booting. To be honest, i've been doing dual booting for a while now so, i did the right thing. the box came with 2TB HDD. so i made 4 partitions with a raw partition just after the windows installation partition I always do manual installation so even if ubuntu didn't detect windows 8, it was ok for me. So i created swap area and finished the installation etc....Grub was install on the only drive there which is sda. After reboot, grub doesn't even come up.So it always boot in windows 8. I did repeat the installation process twice and yield same result. which is weird because this method always works for me so far.Even the laptop am using to write this post is a dual booting windows 7/ mint nadia installed the same way. Is there anything new in windows 8 that i didn't make provision for? Before starting the installation, all i read about was that , windows 8 should be installed first and ubuntu after. I went ahead and disable secure boot from the BIOS and enabled CSM (don't even know what it means) according to Acer custhelp site . I boot from USB and did fdisk -l bellow is the result: ubuntu@ubuntu:~$ sudo fdisk -l WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.
