  • What are my audio devices?

    - by hellocatfood
    I'm attempting to use easycap to record from my camcorder but I'm having a slight problem. Using their test script I'm able to get audio and video. I've noticed that in the script on line 159 it makes a call to "DEV_ADUIO", which is reported as being "plughw:2,0". Exactly what is this device? Is it located in /dev/ somewhere? I've done "ls /dev/" and I can't find anything that would suggest an audio device

Code is below public class DefaultSearch: SqlReaderBase<Restaurant> { protected override string commandText { get { return "Select Name from vw_Restaurants"; } } protected override CommandType commandType { get { return CommandType.Text; } } protected override Collection<IDataParameter> GetParameters(IDbCommand command) { Collection<IDataParameter> parameters = new Collection<IDataParameter>(); parameters.Clear(); return parameters; } protected override MapperBase<Restaurant> GetMapper() { MapperBase<Restaurant> mapper = new RMapper(); return mapper; } } But whenever I tried to build , I am getting error 'T' must be a non-abstract type with a public parameterless constructor in order to use it as parameter 'T' in the generic type or method. Even T here is Restaurant has a Parameterless Public constructor.

  • Adjust timezone of an AVM Fritz!Box 7390

    It's been a while that I purchased an AVM Fritz!Box 7390 but since I'm using this 'PABX' here in Mauritius, I'm not really happy about the wrong time in the logs or handsets connected. Lately, I had some spare time to address this issue, and the following article describes how to adjust the timezone settings in general. The original idea came from an FAQ found in c't 21/11 (for a 7270 written in German language) but I added a couple of things based on other resources online. The following tutorial may be valid for other models, too. Use your common sense and think before you act. Brief introduction to AVM Fritz!Box devices The Fritz!Box series of AVM has been around for more than a decade and those little 'red boxes' have a high level of versatility for your small office or home. High-speed connections, secure WLAN and convenient telephony make a home network out of any network. Whether it's a computer, tablet or smartphone, any device can be connected to the FRITZ!Box. And best of all, installation is so simple that users will be online in a matter of minutes. If you want to have peace of your mind in your small network then a Fritz!Box is the easiest way to achieve that. I'm using my box primarly as WiFi access point, VoIP gateway and media server but only because it came in second after my Linux system. Limitations in the administrative Web UI Unfortunately, there are no possibilities to adjust the timezone settings in the Web UI at all - even not in Expert mode. I assume that this is part of the 'simplification' provided by AVM's design team. That's okay, as long as you reside in Central Europe, and the implicit time handling is correct for your location. Adjusting the timezone I got my device through an order at Amazon Germany already some time ago, and honestly I wasn't bothered too much about the pre-configured (fixed) timezone setting - CET or CEST depending on daylight saving. But you know, it's that kind of splinter at the back of your head that keeps nagging and bothering you indirectly. So, finally I sat down yesterday evening and did a quick research on how to change the timezone. Even though there are a number of results, I read the FAQ from the c't magazine first, as I consider this as a trusted and safe source of information. Of course, it is most important to avoid to 'brick' your device. You've been warned - No support Tinkering with the configuration of any AVM devices seems to be a violation of their official support channels. So, be warned and continue onlyin case that you're sure about what you are going to do. The following solutions are 'as-is' and they worked for my box flawlessly but may cause an issue in your case. Don't blame me... Solution 1 - Backup, modify and restore That's the way as described in the c't article and a couple of other forum postings I found online, mainly from Australia. Login the administrative Web UI and navigate to 'System => Einstellungen sichern' (System => Backup configuration) and store your current configuration to a local file on your machine. Despite some online postings it is not necessary to specify a password in order to secure or encrypt your backup. IMHO, this only adds another unnecessary layer of complexity to the process. Anyway, next you should create a another copy of your settings and keep it unmodified. That's our safety net to restore the current settings in case that we might have to issue a factory setting reset to the box. Now, open the configuration file with an advanced text editor which is capable to deal with Unix carriage returns properly - Windows Notepad doesn't do the job but Wordpad or Notepad++. Personally, I don't care and simply use geany, gedit or nano on Linux. In total there are 3 modifications that we have to apply to the configuration file - one new line and two adjustments. First, we have to add an instruction near the top of file that overrides the device internal checksum validation. Without this line, your settings won't be accepted. Caution: The drectives are case-sensitve and your outcome should read something like this: **** FRITZ!Box Fon WLAN 7390 CONFIGURATION EXPORTPassword=$$$$<ignore>FirmwareVersion=84.05.52CONFIG_INSTALL_TYPE=iks_16MB_xilinx_4eth_2ab_isdn_nt_te_pots_wlan_usb_host_dect_64415OEM=avmCountry=049Language=deNoChecks=yes**** CFGFILE:ar7.cfg/* * /var/flash/ar7.cfg * Mon Jul 29 10:49:18 2013 */ar7cfg {... Then search for the expression 'timezone' and you should find a section like this one (~ line 1113): timezone_manual {        enabled = no;        offset = 0;        dst_enabled = no;        TZ_string = "";        name = "";} We would like to manually handle the timezone setting in our device and therefore we have to enable it and set the proper value for Mauritius. The configuration block should like so afterwards: timezone_manual {        enabled = yes;        offset = 0;        dst_enabled = no;        TZ_string = "MUT-4";        name = "";} We specify the designation and the offset in hours of the timezone we would like to have. Caution: The offset indicates the value one has to add to the local time to arrive at UTC. More details are described in the Explanation of TZ strings. Mauritius has GMT+4 which means that we have to substract 4 hours from the local time to have UTC. Finally, we restore the modified configuration file via the administrative Web UI under 'System => Einstellungen sichern => Wiederherstellen' (System => Backup configuration => Restore). This triggers a reboot of the device, so please be patient and wait until the Web UI displays the login dialog again. Good luck! Solution 2 - Telnet A more elegant, read: technically interesting, way to adjust configuration settings in your Fritz!Box is to access it directly through Telnet. By default AVM disables that protocol channel and you have to enable it with a connected telephone. In order to activate the telnet service dial the following combination: #96*7* #96*8* (to disable telnet again after work has been completed) If you're using an AVM handset like the Fritz!Fon then you will receive a confirmation message on the display like so: telnetd ein Next, depending on your favourite operating system, you either launch a Command prompt in Windows or a terminal in Linux, get your Admin password ready, and you connect to your box like so: $ telnet fritz.box Trying 192.168.1.1...Connected to fritz.box.Escape character is '^]'.password: BusyBox v1.19.3 (2012-10-12 14:52:09 CEST) built-in shell (ash)Enter 'help' for a list of built-in commands.ermittle die aktuelle TTYtty is "/dev/pts/0"Console Ausgaben auf dieses Terminal umgelenkt# That's it, you are connected and we can continue to change the configuration manually. In order to adjust the timezone setting we have to open the ar7.cfg file. As we are now operating in a specialised environment, we only have limited capabilities at hand. One of those is a reduced version of vi - nvi. Let's open a second browser window with the fine manual page of nvi and start to edit our configuration file: # nvi /var/flash/ar7.cfg In our configuration file, we have to navigate to the timezone directives. The easiest way is to search for the expression 'timezone' by typing in the following: /timezone    (press Enter/Return) Now, we should see the exact lines of code like in the backed up version: timezone_manual {                                                                            enabled = no;                                                          offset = 0;                                                         dst_enabled = no;                                                   TZ_string = "";                                                     name = "";                                                        } And of course, we apply the same changes as described in the previous section: timezone_manual {                                                                            enabled = yes;                                                          offset = 0;                                                         dst_enabled = no;                                                   TZ_string = "MUT-4";                                                     name = "";                                                        } Finally, we have to write our changes back to the file and apply the new settings. :wq    (press Enter/Return) # ar7cfgchanged That's it! Finally, close the telnet session by pressing Ctrl+] and enter 'quit'. Additional ideas... There are a couple of more possibilities to enhance and to extend the usability of a Fritz!Box. There are lots of resources available on the net, but I'd like to name a few here. Especially for Linux users it is essential to be able to connect to any device remotely in a  safe and secure way. And the installation of a SSH server on the box would be a first step to improve this situation, also to avoid to run telnet after all. Sometimes, there might be problems in your VoIP connections, feel free to adjust the settings of codecs and connection handling, too. I guess, you'll get the idea... The only frontiers are in your mind.

  • Why can’t two programs access my webcam simultaneously?

    - by qdii
    I first launch cheese and my webcam turns on. I then run vlc to grab the output of /dev/video0 but it fails with: [0x7f3ea40012e8] v4l2 demux error: cannot set input 0: Device or resource busy [0x7f3ea40012e8] v4l2 demux error: cannot set input 0: Device or resource busy [0x7f3ea4002168] v4l2 access error: cannot set input 0: Device or resource busy [0x7f3ea4002168] v4l2 access error: cannot set input 0: Device or resource busy [0x7f3eb4000b78] main input error: open of `v4l2:///dev/video0' failed Whatever pair of video programs I run (skype, cheese, vlc, etc.), the result is always the same: the second program can no longer use the webcam when the first one has already grabbed the output. However I find it curious as video4linux states: In general, V4L2 devices can be opened more than once. When this is supported by the driver, users can for example start a "panel" application to change controls like brightness or audio volume, while another application captures video and audio. My webcam is seen in lspci as 058f:a014 Alcor Micro Corp. Asus Integrated Webcam, but I don’t even know what the underlying driver is, so I can’t check whether my problem is driver-related or not. Any input would be more than welcome!

    I am trying to encrypt an external drive using diskutil CoreStorage on Mac Lion 10.7.4.

  • How to get the permissions right for /dev/raw1394

    - by Mark0978
    I recently upgraded one of my ubuntu machines to Karmic and I'm having trouble getting the permissions of /dev/raw1394 set to 0666. They only thing this machine is used for is recording audio from a firepod which uses /dev/raw1394 via jackd and there are no other FireWire devices connected, so security around this device is not really an issue. If I run as root, everything works as expected, but I have some folks that run the recorder that I don't want to have root access. However, I can't figure out which lines setup the perms I've tied this: /etc/udev/permissions.d/raw1394.rules:raw1394:root:root:0666 And I have this setup (default install) /lib/udev/rules.d/75-persistent-net-generator.rules:SUBSYSTEMS=="ieee1394", ENV{COMMENT}="Firewire device $attr{host_id})" /lib/udev/rules.d/75-cd-aliases-generator.rules:# the "path" of usb/ieee1394 devices changes frequently, use "id" /lib/udev/rules.d/75-cd-aliases-generator.rules:ACTION=="add", SUBSYSTEM=="block", SUBSYSTEMS=="usb|ieee1394", ENV{ID_CDROM}=="?*", ENV{GENERATED}!="?*", \ /lib/udev/rules.d/60-persistent-storage-tape.rules:KERNEL=="st*[0-9]|nst*[0-9]", ATTRS{ieee1394_id}=="?*", ENV{ID_SERIAL}="$attr{ieee1394_id}", ENV{ID_BUS}="ieee1394" /lib/udev/rules.d/50-udev-default.rules:# FireWire (deprecated dv1394 and video1394 drivers) /lib/udev/rules.d/50-udev-default.rules:KERNEL=="dv1394-[0-9]*", NAME="dv1394/%n", GROUP="video" /lib/udev/rules.d/50-udev-default.rules:KERNEL=="video1394-[0-9]*", NAME="video1394/%n", GROUP="video" /lib/udev/rules.d/60-persistent-storage.rules:KERNEL=="sd*[!0-9]|sr*", ATTRS{ieee1394_id}=="?*", SYMLINK+="disk/by-id/ieee1394-$attr{ieee1394_id}" /lib/udev/rules.d/60-persistent-storage.rules:KERNEL=="sd*[0-9]", ATTRS{ieee1394_id}=="?*", SYMLINK+="disk/by-id/ieee1394-$attr{ieee1394_id}-part%n" And I find these lines in /var/log/syslog Apr 30 09:11:30 record kernel: [ 3.284010] ieee1394: Node added: ID:BUS[0-00:1023] GUID[000a9200c7062266] Apr 30 09:11:30 record kernel: [ 3.284195] ieee1394: Host added: ID:BUS[0-01:1023] GUID[00d0035600a97b9f] Apr 30 09:11:30 record kernel: [ 18.372791] ieee1394: raw1394: /dev/raw1394 device initialized What I can't figure out, is which line actually creates that raw1394 device in the first place.

  • Why is mkfs overwriting the LUKS encryption header on LVM on RAID partitions on Ubuntu 12.04?

    - by Starchy
    I'm trying to setup a couple of LUKS-encrypted partitions to be mounted after boot-time on a new Ubuntu server which was installed with LVM on top of software RAID. After running cryptsetup luksFormat, the LUKS header is clearly visible on the volume. After running any flavor of mkfs, the header is overwritten (which does not happen on other systems that were setup without LVM), and cryptsetup will no longer recognize the device as a LUKS device. # cryptsetup -y --cipher aes-cbc-essiv:sha256 --key-size 256 luksFormat /dev/dm-1 WARNING! ======== This will overwrite data on /dev/dm-1 irrevocably.

  • Windows 7 Not Recognizing Camera Nor iPhone as Camera

    - by taudep
    I've been struggling with this one for a few days. I've recently upgraded an older computer to Windows 7 Home Premium. Neither my digital camera (A Canon SD1200IS) nor iPhone are ever detected as cameras, nor ever show up as accessable in Explorer. With the Canon camera, no driver is required. It's supposed to work with the default Windows 7 drivers. However, in the Control Panel's Device Manager, I'm always seeing a yellow icon next to the "Canon Digital Camera" device. I've uninstalled the device and let Windows attempt to reinstall, but it can never find a driver to install. With the iPhone, it's very similar. One big difference, though, is that iTunes can see the iPhone and back it up, etc. However, again when I go to the Device Manager, there's a yellow icon next to the iPhone. I've uninstalled iTunes, reinstalled, rebooted, deleted drivers, and let Window try to reinstall the driver, but it can never find the driver. So there seems to be some correlation that my machine can't detect cameras properly, and that it might be even a lower-level type of driver I'm struggling with. I know that USB however, does work, because I have have an external drive hooked into the machine. I've gone through the web and tried two hours worth of fixes, without success. I feel like if I can get the Canon camera detected, then the iPhone will be on it's way to being fixed too. BTW, I couldn't really find anything of use in the Event viewer. Any and all suggestions welcome.

Any obvious ideas what can go wrong in this case? The most reasonable thing I can imagine is that the SSD is silently dropping some write requests, which eventually leads to an EXT4 filesystem inconsistency (but no disk I/O errors). How can this happen? Is there a relevant configuration option I should ensure to be set correctly? What tools should I use to diagnose the hardware failures? Would it be possible to diagnose the SSD failure without overwriting data?

  • Is it possible to detect nearby Wi-Fi enabled devices, not necessarily on the same network? [closed]

    - by Sky
    first question on StackExchange ever. I hope I got the right board. I'm trying to create a device (either from a standard AP or some other unconventional means) that will be able to detect nearby Wi-Fi enabled devices. For example, if a cellular phone (iPhone for instance) would be carried into the secured area, its MAC address will be logged. A cellular phone is a good example because it's the most common threat that should be detected. Some important points: The detection can be either active or passive, doesn't matter. The detected device might be connected to a different network, or might not be connected to anything at all. I assume most cellular phones are actively probing when not connected, but I'm not sure. It is important to not only identify the breach, but also to identify the device (MAC address). Conventional hardware is only optional. Distance of detection is at least 6 meters (20 feet). Handling one device at a time is good. Speed of detection is important, under 5 seconds is ideal. So my question is, is this even possible? If so, what can I use in order to make this a reality? Thank you for reading!

  • Kerberos service on win2k dc will not start following disk failure

    - by iwilson68
    Hi, I have a win2k (mixed mode domain) with 4 DCS. One of these also acts an exchange 2000 server which uses 2 logical volumes from an MSA 2000 array. AD etc is stored on local drives. We experienced a problem last week when the raid array fell back to a redundant controller and this temporarily meant that the two logical drives were not visible to the server for around 5 minutes and a couple of reboots. The log records these Events as Type: Warning Event Source: Disk Event Category: None Event ID: 51 Date: 06/11/2009 Time: 11:46:23 User: N/A Computer: server1 Description: An error was detected on device \Device\Harddisk1\DR1 during a paging operation. Following these problems, the server “kerberos Key Distribution” service refuses to start with an “error.31 a device attached to the system is not functioning”. All other automatic start services (including net logon) are running and there are no DNS issues etc. All devices are also functioning but the two logical MSA disks are now numbered in the Windows Disk Management MMC as 2 and 4 and I suspect that they may have previously been identified as disks 1 & 2 and perhaps windows still sees this as an ongoing failure?? Replication has not been affected but obviously there are many audit failures in the security log relating to users and workstations presumably linked to the Kerberos issue. Attempting to manually start the kerberos service generates the following in the System Log. Event Type: Error Event Source: Service Control Manager Event Category: None Event ID: 7023 Date: 09/11/2009 Time: 09:46:55 User: N/A Computer: Server1 Description: The Kerberos Key Distribution Center service terminated with the following error: A device attached to the system is not functioning. DCDIAG passes all tests except “Advertising” and “Services” which I believe relate directly to the failure of Kerberos only. Any advice would be appreciated.

  • NetApp NDMP backup with BE 2010 R2 works, restore fails

    - by uuwe
    Hi, I'm having some issues with a new Backup Exec 2010 R2 installation. I configured a NetApp FAS2020 as an NDMP device and want to backup files from the NAS to a tape drive connected to my backup server. I set up ndmpd according to this document (http://www.symantec.com/business/support/index?page=content&id=TECH48957) and created a separate backup user (http://filers.blogspot.com/2006/09/setting-veritas-netbackup-with-non.html). Backup works perfectly, but restoring any file gives me an authentication failed error. The NDMP device has a "global" ndmp user configured in the device tab (tried this with the newly created ndmpd backup user and the netapp root) and I can also configure separate resource credentials in the BE restore job. I have tried setting the same accounts for the "global" ndmp device and the restore credentials and have also tried setting different accounts for them. NDMP debug level is at 5 and this is what shows up in /etc/messages. The session is closed immediately after it has been granted. 16:12:07 PST [Java_Thread:info]: ndmpdserver: ndmpd.access allowed for version = 4, sessionId = 51, from src ip = 192.168.11.17, dst ip = FAS2020-1/192.168.11.75, src port = 50857, dst port = 10000 16:12:07 PST [Java_Thread:info]: Ndmpd51: ndmpd session closed successfully for version = 4, sessionId = 51, from src ip = 192.168.11.17, dst ip = FAS2020-1/192.168.11.75, src port = 50857, dst port = 10000 Running wireshark on the backup server doesn't produce much. It shows a SYN - SYN/ACK - NDMP CONNECT_CLOSE Request from the backup server. The Resource Credentials for the restore job behave very oddly. If I enter NDMP credentials and do "Test All" it fails. If I use my regular domain backup account, it is successful. There are no failed or succeeded logons in the NetApp ndmp log and tracing this check shows that it doesn't even connect to the NAS. This makes me think that this is more likely flaky BE behaviour rather than misconfiguration of the NAS. Here is the options ndmp output: FAS2020-1 options ndmp ndmpd.access all ndmpd.authtype challenge ndmpd.connectlog.enabled on ndmpd.enable on ndmpd.ignore_ctime.enabled off ndmpd.offset_map.enable on ndmpd.password_length 16 ndmpd.preferred_interface disable ndmpd.tcpnodelay.enable off

  • How to disable auto insert notification in Windows 7?

    - by White Phoenix
    Alright, here's the problem. My hard drive activity light on my custom built PC is blinking exactly once every second. Microsoft has this to say on the issue: http://support.microsoft.com/kb/138598 There has been discussion on this issue several months ago: Why does my hard drive LED light blink every second? The problem seems to stem from primarily Windows 7 polling the CD-ROM/DVD drive every second to see if something is inserted. The Windows 7 users in the thread that was linked in the superuser question, https://social.technet.microsoft.com/Forums/fi-FI/w7itprohardware/thread/4f6f63b3-4b58-4154-9298-1566100f9d00, have confirmed that this IS a known issue with Windows 7. Some people point at the motherboard circuitry causing the CD-ROM and SATA activity to both be linked to that hard drive activity, but whatever the case, the temporary solution seems to be to disable the CD/DVD-ROM drive in Device Manager. In fact, disabling the CD/DVD-ROM does stop the blinking, but of course this solution is counterproductive, because I shouldn't have to entirely disable a device to fix this problem. I've done the following suggestions in that thread: Change the autorun registry entry to 0 Completely disable autoplay in the autoplay control panel Disable autoplay in the Local Group Policy Editor. None of these stop the blinking from happening - apparently these solutions work for both XP and Vista, but it seems to be different in Windows 7. So I'm wondering if anyone has found out how to completely disable the polling in Windows 7, or if this will just have to be an issue we will have to deal with. There's no option to disable the auto insert notification when you go to the device within device manager (there was in XP), so I got no idea where this option is hidden, or if there's a registry key entry I could change to stop the polling. Anyone have any idea?

  • QNAP NAS 509 (LINUX) - how to unmout busy volume and find physical disk?

    - by Horst Walter
    On my NAS QNAP TS 509 I do have a technical issue. I need to run e2fsck. This works fine for me on md0 (see below), but how can I unmount the busy devices md9 and sda4 in order to do the same. Whenever I try, I fail because the device is busy. [This part is solved, see below] In order to further track down the issue, I'd need to sort out the physical disk to device relationship. How can I find out this, e.g. md0 is a stripped volume on 2 disk (but I need to find out on what physical disk). Remark: As you can easily derive from my questions, I am not a Linux expert, but manage to get along. /dev/ram0 124.0M 94.1M 29.8M 76% / tmpfs 32.0M 80.0k 31.9M 0% /tmp /dev/sda4 310.0M 103.9M 206.1M 34% /mnt/ext /dev/md9 509.5M 39.2M 470.2M 8% /mnt/HDA_ROOT /dev/md0 1.8T 1.4T 444.7G 76% /share/MD0_DATA tmpfs 32.0M 0 32.0M 0% /.eaccelerator.tmp -- Added -- QNAP seems to be based on Busybox. I do not find something like init / telinit / runlevel. At busybox docs it says that I need to run the below. But in /var/service sv is not available. I want to go to single user mode to unmount the devices. # cd /var/service # sv d * # sv u getty* -- Added, thanks A4L -- This QNAP Box runs a special flavor of Linux, so not all SOPs do apply. In my particular case I found a services.sh script, stopping all services. After that the drive could be unmounted. The information passed by A4L is valid and worth reading it, maybe I'll profit from it next time. Links: http://unix.stackexchange.com/questions/19918/umount-device-is-busy and http://unix.stackexchange.com/questions/15024/umount-device-is-busy-why So the unmount issue is solved, still looking for the best option to find the physical to volume mapping.

  • ASUS EAH5450 Graphics Card (ATI Radeon HD5450 - 1 GB DDR3) on Windows 2003? Anybody got it to work?

    - by JJarava
    Hi all! I've just bought an ASUS EAH5450 Graphics Card (ATI Radeon HD5450, 1 GB DDR3) for my main system, but I haven't been able to make it work under Windows 2003 (my OS in that system). When I plugged the card, I got a couple of "installing drivers" prompt for things such as "ATI High Definition Audio Device" that got themselves sorted out of the Internet, and then a "Standard VGA Graphics Adapter". The CD that came with the card installs something called "ATI Catalyst Install Manager" and .net 2.0, but no drivers. I've downloaded the latest (WinXP 32bits) drivers from ATI, and the experience is the same: I don't get any drivers installed. My Motherboard is an ASUS A8N-SLI with nVidia nForce 4 chipset (for an Athlon 64X2, somewhat old), but my previous card was an ATi Radeon X700, so it's been working with ATI cards before. On POST, during boot I see a "Display Card" Device (Vendor ID 1002-68F9-0300) and a "Multimedia Device" (1002-AA68-0403), and when viewing the properties of the "Standard VGA", they match the device ID. Any hints? I'd really hate having to get rid of the card, and I'm sure it's not that strange what I'm trying to do...

  • Broken fonts in Konsole KDE 4.3.4

    - by depesz
    I have a strange situation - after some upgrades a couple of days ago fonts in KDE Konsole broke. To make it more specific - standard fonts look more or less OK, but when I use my national characters (like acelnsózz) they all look broken - like from another font, or badly scaled. The same problem doesn't exist in GNOME Terminal. I usually use the Terminus font, so I used this for demonstration, but it shows in other fonts as well - if that will be necessary I will provide list. Konsole shot: GNOME Terminal shot: As for my settings: =$ cat /etc/X11/xorg.conf Section "Device" Identifier "Builtin Default intel Device 0" Driver "intel" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Monitor Vendor" ModelName "Monitor Model" EndSection Section "Screen" Identifier "Builtin Default intel Screen 0" Device "Builtin Default intel Device 0" Monitor "Monitor0" EndSection Section "InputDevice" Identifier "touchpad" Driver "synaptics" Option "CorePointer" EndSection Section "ServerLayout" Identifier "Builtin Default Layout" Screen "Builtin Default intel Screen 0" InputDevice "touchpad" EndSection =$ xdpyinfo | grep -E resolution\|dimensions dimensions: 1680x1050 pixels (444x277 millimeters) resolution: 96x96 dots per inch I tried forcing DPI in system settings (to 120), or adding monitor size to xorg.conf - so far nothing helped. Any idea on what should I do to make it work sanely again?

  • Recover LVM2 volume group after one HDD failed

    - by Bernd
    I had two HDDs, each one containing a LVM partition which formed a volume group. Then I had two LVs, one for my / directory and one for my /home/ directory. Yesterday where I had my / dir failed. I'm trying to recover at least my /home/ dir. What I've done so far: Boot a live system Extract LVM2 metadata from the working HDD using dd Copy metadata to /etc/lvm/backup/vg0 Now I'm trying to do this: pvcreate --restore /etc/lvm/backup/vg0 --uuid "[uuid of my working hdd]" /dev/sdb2 But I always get: Couldn't find device with uuid '[uuid of broken hdd]'. Couldn't find device with uuid '[uuid of working hdd]'. Device /dev/sdb2 not found (or ignored by filtering). I confirmed that /dev/sdb2 exists and I've commented out all filtering settings from /etc/lvm/lvm.conf so I don't know what might be causing pvcreate not to find the device. So: What might be the problem? Is it even possible to restore this partition? (As I'm writing this I'm starting to think it's impossible D:) Edit: Okay, looks like I've got it figured out. I was using a Ubuntu 8.10 CD (yeah, I know it's not supported anymore) and it seems that was the problem. When I started from a Ubuntu 10.04 CD everything worked 'fine', I could mount my LVM partitions partially without problems. (Will answer the question in 4 hours. But if anyone has still got some hints/tips, please share! :)

  • How to manage mounted partitions (fstab + mount points) from puppet

    - by Cristian Ciupitu
    I want to manage the mounted partitions from puppet which includes both modifying /etc/fstab and creating the directories used as mount points. The mount resource type updates fstab just fine, but using file for creating the mount points is bit tricky. For example, by default the owner of the directory is root and if the root (/) of the mounted partition has another owner, puppet will try to change it and I don't want this. I know that I can set the owner of that directory, but why should I care what's on the mounted partition? All I want to do is mount it. Is there a way to make puppet not to care about the permissions of the directory used as the mount point? This is what I'm using right now: define extra_mount_point( $device, $location = "/mnt", $fstype = "xfs", $owner = "root", $group = "root", $mode = 0755, $seltype = "public_content_t" $options = "ro,relatime,nosuid,nodev,noexec", ) { file { "${location}/${name}": ensure => directory, owner => "${owner}", group => "${group}", mode => $mode, seltype => "${seltype}", } mount { "${location}/${name}": atboot => true, ensure => mounted, device => "${device}", fstype => "${fstype}", options => "${options}", dump => 0, pass => 2, require => File["${location}/${name}"], } } extra_mount_point { "sda3": device => "/dev/sda3", fstype => "xfs", owner => "ciupicri", group => "ciupicri", $options = "relatime,nosuid,nodev,noexec", } In case it matters, I'm using puppet-0.25.4-1.fc13.noarch.rpm and puppet-server-0.25.4-1.fc13.noarch.rpm.

  • Use Alladin eToken with ThunderBird and other tool

    - by Yurij73
    I'm looking for an example on how to setup the eToken PRO Java device to work with Mozilla Thunderbird and with other Linux tool such as PAM logon. I installed distributed pkiclient-5.00.28-0.i386.RPM from the official product page eToken Pro but that tool only handles importing/exporting certificates on the device. I read a glance an old HOWTO from eToken on Linux, but I couldn't install pkcs11-lib for this device as recommended for Thunderbird use this crypto device.
