• Getting the most out of a Mac mini as a media center

  - by celebritarian

  Hello! I own an old Mac mini from 2006 (maybe early 2007). It's got an Intel Core Solo 32-bits CPU and 512 MB RAM. 160 GB HDD. The GPU is an integrated chip… Currently, my Mini is sitting under my LCD TV (720p). It's plugged in via a DVI to HDMI cable. It's currently running Leopard. And unfortunately, Snow Leopard can't be installed on a device with less than 1 GB of RAM… So, my Mac mini isn't exactly powerful. Also, it's slow and Mac OS X is not a pleasant experience on my Mini right now. It feels slow and heavy. I want to use my Mac mini as a media center/player. I want to be able to play video files in 720p (H.264, Matroska/MOV files). So basically, playing high-def videos is all I want to do with my Mini. What OS should I install? Stick to OS X? Optimize for video playback? Or should I install another OS — like Win XP, Ubuntu or any other Linux dist? Then, will my Mini be able to play 720p videos smoothly, even though the CPU and GPU aren't that powerful and with the limit of 512 MB of RAM? Appreciate all help. Thanks in advance!

• Best CPUs for speeding up compiling times of C++ w/ DistGCC

  - by Jay

  I'm putting together a distributed build farm with DistGCC to speed up our teams compile times and just looking for thoughts on which processors to use in the hosts. Are we going to get a noticeable decrease in time using 8 cores vs. 4-hyperthreaded cores? Big difference in time between i7 and Xeon? etc, etc. Just need advice from people who've put together kick-a build clusters. We've got a majority of the normal things to speed up builds in place (pre-compiled headers, ccache, local gigabit connections between them, tons of ram, etc) so please just give advice on the best processor to use. And money is a factor, but anythings doable if the performance increase is noticeable. Thanks. Jay EDIT: Although any advice IS welcome, please refrain from "Do this first" posts as we're not planning on skimping on things like SSD, maxed out RAM, etc. My personal system is a iMac Quad-core i5 with 8GB of RAM. When I build our project locally, my processor floats around 99-100% a majority of the time, which makes me assume it is a bottleneck, even if you made everything else faster. My ram on the other hand doesn't even get close to maxing out. It's also worth noting that I did research this, however every discussion I could find was primarily for gaming machines, which is obviously a different beast in usage. These machines won't even have monitors or anything but integrated graphics since they have one purpose: Build freakin fast. (hopefully)

• New XPC: No video, no ethernet link, but drive spins

  - by Mike Pennington

  I bought a Shuttle XPC SH67H3 with integrated video. I installed: An Intel i5 2450P 16GB DDR3 RAM A SATA hard drive from my old linux server that still is bootable I have both power connectors plugged into the motherboard. I realize that the Intel i5-2450P doesn't have video capabilities; however, the drive spins like it's doing something useful. It seems like I should get an ethernet link light when I fire this up. I plan to run this headless anyway, so it would be really nice if I could figure out how to run this without a video card at all. I know the IP address and login info for the linux install on the disk. I plugged in speakers, but get no bios beeps when I power it up. Shuttle's bios manual has nothing in there that indicates I should have problems in this configuration. My questions: Is there a reason that the missing video card would block usage of the ethernet port? Are there settings on the motherboard / bios I can change to get this working?

• Single Sign On for intranet with Apache and Linux MIT Kerberos

  - by Beerdude26

  Greetings, I am looking for a way to do a single sign on to an intranet in the following manner: A Linux user logs on via a graphical frontend (for example, GNOME). He automatically requests a TGT for his username from the MIT Kerberos KDC. Via some way or another, the Apache server (which we'll assume is on the same server as the KDC), is informed that this user has logged in. When the user accesses the intranet, he is automatically granted access to his web applications. I don't think I've seen this kind of functionality while searching the net. I know the following possibilities exist: Using an authentication module such as mod_auth_kerb, a user is presented with a login prompt to enter his username and password, which are then authenticated against the MIT Kerberos server. (I would like this to be automatic.) IIS supports integrated Windows logon via ASP.Net when the user is part of an Active Directory. (I'm looking for the Linux / Apache equivalent.) Any suggestions, criticism and ideas are highly appreciated. This is for a school project to show a proof-of-concept, so every handy piece of information is more than welcome. :)

• SharePoint Business Connectivity Services (BCS) Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'

  - by g18c

  I am running SharePoint 2010 with SQL 2012, I am trying to get Business Connectivity Services (BCS) running but I am facing a double-hope authentication issue. Everytime I try to connect to the external BCS list created in SharePoint designer, I get the error Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. In the event viewer on the SQL server I see a login failure for an anonymous user from the SP server IP address. Background information below: I have enabled Kerberos under SharePoint Central admin. I have the following AD domain accounts: SP_Farm - main website pool SP_Services - for SharePoint services (including BCS) SQL_Engine - SQL database engine I then created the following with SetSPN: SetSPN -S http/intranet mydomain\SP_Farm SetSPN -S http/intranet.mydomain.local mydomain\SP_Farm SetSPN -S SPSvc/SPS mydomain\SP_Farm SetSPN -S MSSQLSvc/SQL1 mydomain\SQL_DatabaseEngine SetSPN -S MSSQLSvc/SQL1.mydomain.local mydomain\SQL_DatabaseEngine SetSPN -S MSSQLSvc/SQL1:1433 mydomain\SQL_DatabaseEngine SetSPN -S MSSQLSvc/SQL1.mydomain.local:1433 mydomain\SQL_DatabaseEngine I then delegated the AD accounts for any authentication protocol to the following: SP_Farm - SP_Farm (http service type, intranet) SP_Farm - SQL_DatabaseEngine (MSSQLSvc, sql1) SP_Service - SP_Service (SPSvc) SP_Service - SQL_DatabaseEngine (MSSQLSvc, sql1) I have also checked the WFE is being logged on to with Kerberos, with the WFE server event log showing event ID 4624 with Kerberos authentication, this is OK. The SQL is also showing connections authenticated as Kerberos from the WFE with the following query: Select s.session_id, s.login_name, s.host_name, c.auth_scheme from sys.dm_exec_connections c inner join sys.dm_exec_sessions s on c.session_id = s.session_id Despite the above, credentials are not passed from the client through the SharePoint server to the SQL server, only the anonymous account is used. I get the following error in the WFE server for 'BusinessData' ID 8080: Could not open connection using 'data source=sql1.mydomain.local;initial catalog=MSCRM;integrated security=SSPI;pooling=true;persist security info=false' in App Domain '/LM/W3SVC/1848937658/ROOT-1-129922939694071446'. The full exception text is: Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. If I set a username and password with the Secure Store Service and set the external list to use the impersonated credentials, the list works. Any ideas what I have missed and what can be tried next?

• Extract archive here, autodetect subfolder

  - by lorancou

  I use 7-Zip under Windows 7 to extract all kind of archives. The ever-running problem is that there is not a single way to handle subfolders. Some people create their archives like this (let's call it type A): . +-- subfolder ¦   +-- file 1 ¦   +-- file 2 ¦   +-- ... "Extract Here" will extract everything to subfolder/, which is fine; "Extract to <Folder>" will create an extra subfolder level, which is annoying. And other people create them like that (let's call it type B): . +-- file1 +-- file 2 +-- ... "Extract Here" will populate the current folder, which can bring a lot of mess if this folder already contains tons of other files, and which is very annoying; "Extract to <Folder>" will create a subfolder and conveniently stuff it with the archive content, which is fine. So this leaves two options: always choose to "Extract to <Folder>" and live with the extra subfolder for type A archives. Or open the archive before extracting it to check if this is a type A or B, and then appropriately select "Extract Here" or "Extract to <Folder>". I usually do the latter, but I just discovered that KDE is offering a very handy Extract Archive Here, Autodetect Subfolder feature that automates that. It'll "Extract Here" if there's only one subfolder in the archive, otherwise it'll "Extract to <Folder>". I love this idea. Is there a Windows 7 tool offering this option? Preferably integrated in the explorer context menu? Maybe it's hidden somewhere in 7-Zip and I just didn't find it?

• Why does Windows 7 always automatically change the input or keyboard language?

  - by B-Ball

  I am wondering why Windows 7 always automatically changes my input or keyboard language. I've a notebook with an integrated QWERTY keyboard English (United States). Traveling, I use that one but, additionally, I've my own as well as a much better keyboard at home which is a QWERTZ keyboard German (Germany). Thus, being at home, I'd like to use my QWERTZ keyboard. Unfortunately, Windows 7 does not play along at this one. Every time, I start up my notebook, it is usually set to English (United States) but that's not the problem. In case, I'd use my notebook QWERTY keyboard English (United States), that's fine. However, if I start up my notebook and I'd like to use my QWERTZ keyboard German (Germany), I usually press ALT + Left Shift in order to switch from English (United States) to German (Germany) and Windows 7 switches the input language but only for the program that is currently open. If my input language is set to German (Germany) and I, e.g., open NotePad, Windows 7 automatically switches my input language to English (United States). This is very annoying since I've to change the input or keyboard language to German (Germany) every time I open up a new program. Why doesn't Windows 7 stay with one input language if I changed it manually by pressing ALT + Left Shift? Why doesn't the manual change of the input or keyboard language apply for the whole Windows 7? Why does it only affect the currently opened program? Since I've two keyboards with two different layouts, I seriously need to have both of the keyboards languages installed. I tried both of the below settings in order to find a solution for my problem. Currently, I am using the first option, two input languages. First option: two input languages: Second option: two keyboard languages:

• Ubuntu: how to get audio to work in both Spotify (under Wine) and Flash (in Firefox)?

  - by Jonik

  I'm running Spotify on Linux using Wine. Sound worked great (even though the sound test in winecfg failed!), until I installed alsa-oss package yesterday to get Flash sound working in Firefox. Now Spotify says: "There is a problem with your sound card. Spotify can't play music." So the question is, how to get the sound in Spotify working again, so that it also keeps working in Flash & Firefox? Tweak some ALSA settings? Spotify settings? Add/remove some packages? By the way, curiously, now that sound doesn't work in Spotify, winecfg's "Test Sound" does work! This is Ubuntu 8.04 (Hardy). Sound card / driver is probably an integrated AC'97. Please mention if any additional information about the system is needed! Update: I have Flash 10 installed (outside the packaging system, using $MOZ_PLUGIN_PATH env variable), but also had Flash 9 from flashplugin-nonfree package - and the earlier version was being used by Firefox! Based on what Mike Arthur said about Flash and alsa-oss, I removed the older Flash (flashplugin-nonfree package) and alsa-oss - and Flash sound still works, which is nice. But for some reason Spotify still doesn't play sound, even though things should now be like they were originally... Update 2: Got it working, all smoothly, finally.

• Authenticated User Impersonation in Classic ASP under IIS7

  - by user52663

  I've recently moved one of our servers from Server 2003 and IIS6 to Server 2008 R2 and IIS7 (technically IIS7.5 I suppose). In doing so I am transitioning a small account management tool written in classic ASP and have run into a problem with user impersonation. Extensive searching hasn't been much help so far. Under IIS6, the site was configured to impersonate the logged-in user. Thus, if a domain admin logged in, he was able to run commands to create user directories, adjust permissions, etc. Using Procmon you can see the processes executing as that user. This worked fine. However, with the same code under IIS7, I am unable to get this behavior. I have enabled Basic Authentication, disabled Anonymous Auth, enabled impersonation and have changed the app pool to classic instead of integrated pipelining. Everything seems to be configured correctly, however, all the processes launched by the classic ASP site continue to run as the default AppPool identity and not the logged-in user. If it matters, programs are being launched with code such as: set Wsh = Server.CreateObject("WScript.Shell") Wsh.Run("cmd.exe /C mkdir D:\users\foo") Monitoring via Procmon shows cmd.exe being run as either "Classic .NET AppPool" or "DefaultAppPool" depending on the pipeline mode. Any suggestions on how to get the classic ASP site to impersonate and execute as the authenticated user would be great. Thanks!

• IIS Windows Authentication not working in Internet Explorer via host name; works via IP

  - by jkohlhepp

  I'm trying to get a new Windows Server 2003 box working to host an ASP.NET application that uses Windows Authentication. Here's some info: IIS Anonymous Access is diabled IIS Integrated Windows Authentication is enabled I've tried it with and without Digest Authentication and it is the same result Both my machine and the server are in same active directory domain on the same intranet I'm using IE 6 My symptoms: In Firefox, via either IP or host name, a login box pops up, and if I enter my NT credentials, it works. In IE, via the server IP address, it works perfectly with no login box. In IE, via the server host name, it pops up a login box but even if I put in the correct credentials, it just pops up the box again. This is the problem. Why won't windows auth work in IE via host name but it will via IP address? Edit: Here's something else interesting. If I go into my Internet Explorer advanced settings and disable Windows Authentication, it seems to work just fine. And by work I mean that my test .NET app sees my NT ID as the current user.

• Internet Connection not working - USB LAN connection - from particular modem

  - by Paul

  I am trying to fix Internet connection on a friends Dell inspiron 1720 with XP service pack 3. It has an integrated network card that stopped working, after powering down/up the modem still didnt work I brought it back to my place to try a few things ie check cable, update driver etc... still didnt work. So I bought a USB LAN connector. It didnt work straight away but I went to configure the properties and changed the ConnectionType from AutoSense to 100 BaseT 10BaseT Full_Duplex, I basically just tried them all. From my place when connected to my desktop - 10 BaseT and 10BaseT Full_Duplex worked. From my place When connected to their laptop - 10 BaseT and 10BaseT Full_Duplex worked. Happy I went back to my friends house confident it would all work, and it didnt. Brought it back to mine and it did. While there, in Network Connections the connection is there recognized, enabled, 'working properly' it just says not connected. Also there is no led on the USB connector While at mine as above except there is an led on the USB connector and it says connected. Other difference I can think of is they have a cable modem, I'm plugged into the back of a Belkin wireless router - would this make a difference? Any other ideas what to try? (Would getting the model of the cable modem help anyone?) The USB connector is "DM9601 USB to Fast Ethernet"

• Where is the TFS database?

  - by Blanthor

  I've been using TFS 2010 with no problems. I tried adding a user and I got the following error message. "TF30063: You are not authorized to access <serverName>\DefaultCollection. -The remote server returned an error: (401) Unauthorized." I remoted into the server, <serverName>, and opened the TFS Console. The logs mentioned a connection string: ConnectionString: Data Source=<serverName>\SS2008;Initial Catalog=Tfs_DefaultCollection;Integrated Security=True While remoted in I open SQL Server 2008 Management Studio opening the (local) server with Windows Authentication. It shows the connection to be (local)(SQL Server 9.04.03 - <serverName>\Admin), and there is no Tfs_DefaultCollection database. Can someone tell me what is going on? Was I wrong in connecting to this instance of the database (i.e. Is the log file the wrong place to find the connection string)? Is the database so corrupted that SQL Manager Studio cannot see it anymore, although TFS could? Should I be logging into Management Studio as user SS2008? btw I don't know of any such credentials.

• After update to Windows 8.1 brigthness isn't working (changing)

  - by Bibo

  I just update my Windows 8 to Windows 8.1 by Windows Store and I have some problems. My notebook is Acer Aspire Timelinex 3820TG and I know it's little old for Windows 8 but I install them and works fine (I updated my HDD to SSD). Now I just updated Windows and I have problem with changing brightness on my dedicated graphic card (Ati HD 5650). First I can changing brigthness with fn + keys but It just changing level in OS. No change in real. I tried reinstall drivers, install drivers for my card from Acer with compatibility to Windows 7 and without change. When I switch to integrated card changing brightness works. I think the problem is with drivers but I don't know how to get it working. Thanks for help Bonus question: I have another problem (but this one is not so important). Does anyone knows what msietxghh.exe is doing? Everytime when my system runs (after update) I get message that this program stops working but I just cancel and looks everything works fine.

• How to run the CPU at something like 75%?

  - by Tobias Kienzler

  My notebook is too old for me to invest into a new fan (it will simply be replaced by a new one when the final heat death occurs), but when it runs on full speed I feel like sitting in front of a vacuum cleaner with integrated cooking... I'm currently using NHC, the Max Battery mode of which let's the CPU run at 50% (~800 MHz). That's fine for most applications, and both temperature and noise remain low. However, on some occasions I need a bit more speed, more around 75% maybe. Can I set the power saving settings somehow so that the CPU won't surpass 75% of it's capability so that an acceptable compromise between power and noise is achieved? I can't set the CPU frequency in the BIOS and since on rare occasions I'd like to be able to switch to 100% without much hassling, hardware solutions like setting jumpers are no option. This answer to a similar (linux!) question mentions NHC should be able to offer these options, but for me they are all greyed out: The notebook is an Asus Z9200K, I guess NHC doesn't support its chipset enough for these advanced options.

• IIS6: How to troubleshoot a 404 error in an ASP.NET application?

  - by Tomalak

  I have an ASP.NET application on a Windows Server 2003/IIS6 that refuses to run for some reason (it's the Xerox Centre, if that info helps). It has been working flawlessly before though on this server. Now, all I get if I try to open the app homepage (http://some.intranet.server/XeroxCentreWareWeb/) is a "404 - File or directory not found" error. The app is configured to run in it's own app pool, which runs as Network Service. The Network Service account has read access to the configured directory. If I stop the app pool, I get the expected "Service Unavailable" message, meaning the app and its pool are wired correctly I tried to track down any file permission issues with procmon - nothing to be seen. There isn't even an access to the web app directory happening when the page loads. Interestingly, according to procmon, the web server accesses the 401-2 custom error file (Logon failed due to server configuration) first, but then decides to send the 404 down to the client. EDIT: The app runs with Windows-integrated authentication. Regular users have access to the app directory as well (I would have noticed file system "ACCESS DENIED" messages in procmon, if there had been any.) This makes me think that there is some kind of weird permission problem that occurs even before the application files are being accessed. I just have no idea where to look. I've tried to run the app pool as Local System for a test, but to no avail. What else could I check in this case?

• Fully FOSS EMail solution

  - by Ravi

  I am looking at various FOSS options to build a robust EMail solution for a government funded university. Commercial options are to be chosen only in the worst case scenario. Here are the requirements: Approx 1000-1500 users - Postfix or Exim? (Sendmail is out;-)) Mailing lists for different groups/Need web based archive - Mailman? Sympa? Centralised identity store - OpenLDAP? Fedora 389DS? Secure IMAP only - no POP3 required - Courier? Dovecot? Cyrus?? Anti Spam - SpamAssasin? what else? Calendaring - ?? webmail - good to have, not mandatory - needs to be very secure...so squirrelmail is out;-)? Other questions: What mailbox storage format to use? where to store? database/file system? Simple and effective HA options? Is there a web proxy equivalent to squid in the mail server world? software load balancers?CARP? Monitoring and alert? Backup? The govt wants to stimulate the local economy by buying hardware locally from whitebox vendors. Also local consultants and university students will do the integration. We looked at out-of-the-box integrated solutions like Axigen, Zimbra and GMail but each was ruled out in favour of a DIY approach in the hopes of full control over the data and avoiding vendor lockin - which i though was a smart thing to do. I wish more provincial governments in the developing world think of these sort of initiatives As for OS - Debian, FreeBSD would be first preference. Commercial OS's need not apply. CentOS as second tier option...

SQL Server Configuration Manager shows that Shared Memory, TCP/IP, and Named Pipes are enabled for SQL Native Client 10.0 Configuration, SQL Native Client 10.0 Configuration (32bit), and SQL Server Network Configuration (SQLEXPRESS). The SQL Server (SQLEXPRESS) and SQL Server Reporting Services (SQLEXPRESS) services are running. When I create a system DSN, my driver choices are SQL server (sqlsrv32.dll 4-10-09), which gives a generic wizard, and SQL Server Native Client 10.0 (sqlncli10.dll 7-10-08), which gives the SQL Server 2008 wizard. I choose the latter. I enter name, description, and have tried both MyPCName and 127.0.0.1 for the server name (browsing turns up nothing). After clicking Next, I leave it at Integrated Windows authentication, and leave Connect to server for additional options checked. After clicking Next, I get the error above. I know it's probably a simple answer, (permission issue?) and I'm a SQL noob, so I appreciate anything that would point me in the right direction. Thanks!

• How to choose which network connection provides the default gateway in Windows XP

  - by Cathy

  I have a laptop with an integrated NIC and a WiFi connection. Both the wired and wireless networks I am using can access the Internet. Win XP is routing all traffic through the wireless network. I want to force it to route everything through the wired network when it is available (i.e. when I am sitting at my desk with the laptop docked) and through the wireless when that is the only option (i.e. when I have undocked my laptop and carried it to a conference room, or if I am out of the office working on a different WiFi network). The wireless connection cannot be established until after I am logged into Windows, so it's always the second network to become available to the OS. I have manually overridden the metric values in the TCP/IP configurations so that the NIC has metric 10 and the WiFi has metric 20. However, Windows is still picking the WiFi adapter's address as the Default Gateway, so this isn't helping. If I manually disable and re-enable the WiFi adapter, then it will switch the default gateway to the wired network and stay that way until I shutdown Windows. How can I tell Windows XP not to replace the default gateway when the WiFi connection is first enabled?

• How to get a higher resolution on Ubuntu 11.04 using an intel chipset

  - by Saif Bechan

  I have a bit slow PC here, so I decided to put Ubuntu 11.04 on it. It use to run Windows Vista on a resolution of 1280x1024, so both my hardware and monitor support it. Now I'm on Ubuntu, but can only run 1024x768, and the screen is not that bright. Its like when you don't have the right drivers on a Windows machine. Now i'm new to linux, so I do not know what do do. I have an onboard Intel chipset i965. Maybe this is some useful information, I read something about it on a forum: lspci 00:00.0 Host bridge: Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller (rev 02) 00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 02) 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 01) 00:1c.0 PCI bridge: Intel Corporation N10/ICH 7 Family PCI Express Port 1 (rev 01) 00:1c.1 PCI bridge: Intel Corporation N10/ICH 7 Family PCI Express Port 2 (rev 01) 00:1d.0 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #1 (rev 01) 00:1d.1 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #2 (rev 01) 00:1d.2 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #3 (rev 01) 00:1d.3 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #4 (rev 01) 00:1d.7 USB Controller: Intel Corporation N10/ICH 7 Family USB2 EHCI Controller (rev 01) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1) 00:1f.0 ISA bridge: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge (rev 01) 00:1f.1 IDE interface: Intel Corporation 82801G (ICH7 Family) IDE Controller (rev 01) 00:1f.2 IDE interface: Intel Corporation N10/ICH7 Family SATA IDE Controller (rev 01) 00:1f.3 SMBus: Intel Corporation N10/ICH 7 Family SMBus Controller (rev 01) 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

• Can Xen be configured to dedicate only one port of a dual-port NIC to a domU?

  - by jamieb

  I'm using CentOS 5.4 on my dom0 with a stock Xen kernel. I'm attempting to use the pciback module to hide some of the Ethernet ports from the host and reserve them for a domU I intend to use for a firewall (process described here). However, when I launch the domU, I get the following error message: Using config file "/etc/xen/firewall". Error: pci: improper device assignment specified: pci: 0000:01:04.0 must be co-assigned to the same guest with 0000:01:06.0, but it is not owned by pciback. lspci gives me the following output: 00:00.0 Host bridge: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub (rev 02) 00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02) 00:1d.0 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #1 (rev 01) 00:1d.1 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #2 (rev 01) 00:1d.2 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #3 (rev 01) 00:1d.3 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 (rev 01) 00:1d.7 USB Controller: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller (rev 01) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1) 00:1f.0 ISA bridge: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge (rev 01) 00:1f.2 IDE interface: Intel Corporation 82801GB/GR/GH (ICH7 Family) SATA IDE Controller (rev 01) 00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 01) 01:04.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

• /dev/input/uinput Device appears to be 'broken'

  - by Adam Luchjenbroers

  I'm trying to setup Pystromo so that I can remap the keys on my Belkin N52TE gamepad. Pystromo basically captures the key strokes and then outputs the remapped keystrokes to the uinput device. However, at the moment it simply swallows the input and outputs absolutely nothing. I've tracked the issue to something being wrong with my uinput device, with the smoking gun being: # ls -l /dev/input/uinput crw-rw---- 1 root plugdev 10, 223 Dec 31 2009 /dev/input/uinput # cat /dev/input/uinput cat: /dev/input/uinput: No such device The uinput module is loaded, and can be clearly seen via lsmod. Anyone seen this before, or can think of something worth attempting? Current Setup Gentoo Linux Kernel 2.6.32 (Gentoo Sources 2.6.32-r1) HP DV7 Laptop Output dmesg dmesg | grep uinput does nothing, and no new lines appear if I run modprobe -r uinput && modprobe uinput. Yet the uinput module can clearly be seen when running lsmod: # lsmod | grep uinput uinput 6200 0 lsusb # lsusb Bus 005 Device 003: ID 050d:0200 Belkin Components Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 002: ID 1532:0101 Razer USA, Ltd Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 002: ID 5986:0143 Acer, Inc Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 007 Device 002: ID 03f0:171d Hewlett-Packard Wireless (Bluetooth + WLAN) Interface [Integrated Module] Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub lsusb -v PasteBin Update Hmm, updating evdev and hal seems to have partially fixed it. /dev/input/uinput still can't be accessed but Pystromo is now remapping keys successfully. I'm a little bit mystified about what's going on here, but it seems that my understanding of how all this works is flawed. Since I've posted a bounty, I'll leave this here for someone to post an explanation for how user-space input devices work under the hood.
