• How to secure a group of Amazon EC2 instances

  - by ks78

  I have several Amazon EC2 instances running Ubuntu 10.04 and I've recently started using Amazon's Route 53 as my DNS. The purpose of doing that was to allow the instances to refer to each other by name rather than private IP (which can change). I've pointed my domain name (via GoDaddy) to Amazon's name servers, allowing me to access my EC2 webservers. However, I noticed I can now access the EC2 instances which I don't want to be public, such as the dedicated MySQL Server. I was thinking Amazon's Security Groups would still be in effect when using Route 53, but that doesn't seem to be the case. Before I started using Route 53, I was thinking of having one instance run a reverse proxy, which would help protect the web servers behind it. Then IP-restrict all the other instances. I know IP restricting can be done using the firewall within each instance, but should I ever need to access them from another IP address, I'd need a way in. Amazon's control panel made it a breeze to open a port when necessary. Does anyone have any suggestions for keeping EC2 instances secure, but also accessible to their administrator? Also, what's the best topology for a group of EC2 instances, consisting of web servers and a dedicated database server, from a security perspective? Does having a reverse proxy server even make sense?

• How to disable monitor auto detection in Windows 7?

  - by Jay Yother

  I am currently running Windows 7 Ultimate 64-bit with a dual monitor setup with an NVIDIA 7950 GT graphics card. One monitor is dedicated to this machine and the other monitor is connected to a DVI KVM switch. When I switch to my other computer, Windows 7 disables the monitor. However, when I switch back it does not re-enable the monitor. The only circumstance that automatically re-enables the second monitor is when I switch back after Windows has put the monitors into power save mode. I am continually having to bring up the NVIDIA control panel to have it re-enable the monitor. Under Windows XP I would just disable the NVIDIA service to prevent it from auto-detecting the monitor (which doesn't solve the problem under Win7), and in Vista there was a registry hack that would prevent this. It looks as though that has been removed in Windows 7. I have found similar questions posted on this site, but nothing that matches my problem exactly. The following link is the question that comes the closest, but does not provide a solution to the problem. http://superuser.com/questions/96683/how-to-fix-monitor-detection-on-windows-7 Is there a way in Windows 7 to disable monitor auto-detection? Update: I just added a second graphics card to my Windows 7 64-bit machine. I plugged one monitor into each graphics card. Now, when I use the KVM switch to switch back and forth it will re-enable the second monitor like it should. There are however, a few quirks with this. If I have a program maximized on the second monitor and it has focus, when I switch it will move to monitor 1. If I have a program maximized on the second monitor and it does not have focus, when I switch it will behave like it is minimized and when I bring it back up it will show up maximized on monitor 1. Definitely better than it was, but still looking for a way to disable the auto-detection.

• How to perform this Windows 7 permissions change on many files via GUI or command line

  - by hippietrail

  After using my external hard drive on another Windows 7 computer to tweak photos with Windows Live Photo Gallery then upload them to Facebook I found the modified images were now not visible on the original Windows 7 computer. I'm not sure if the things I tried to get it working subsequently changed anything, but I do know this is the sequence of actions that makes the permissions of the modified files match those of the unmodified files: Right click on broken image file, select "Properties" On the "Security" tab press the "Advanced" button In the "Permissions" tab press the "Continue" button with the shield icon on it Tick the box marked "Include inheritable permissions from this object's parent Click the "Remove" button to remove the only current entry "Type: Allow, Name: Administrators (XYZ\Administrators), Permission: Full control, Inherited From: OK on the "Permissions" tab. OK on the "Security" tab. Now this same procedure does not work at the folder level. It results in "access denied" dialogs. I'm looking for some way to perform this exact modification on all the images I edited on the other computer. I'm happy to use the Windows GUI in Explorer or any other included tools. I'm happy to use the Windows command line. I'd prefer not to use a third-party tool since I'd have to be satisfied it's not doing anything else. I'm not looking for a different way to change permissions to other settings to make an external drive full of photos editable on multiple computers. At least not in this question.

• RHEL 5.3 Kickstart - How specify location of individual package in Workstation folder?

  - by Ed

  I keep getting "package does not exist" errors during the install. I made a kickstart ISO to create an unattended install of a RHEL 5.3 build machine for C++ software releases. It pulls the kickstart config file from our internal web server. This is handy; it makes it easy to test and modify without having to make a new ISO. And I plan to check it in to version control if I can get it working. Anyway, the rpm packages are located in two folders on the disk; Client and Workstation. The packages install fine for the ones that are physically located under the Client folder. It cannot find those under the Workstation folder such as as doxygen and subversion complaining that packages do not exist. Is there a way to specify the individual package location? # ----------------------------------------------------------------------------- # P A C K A G E S # ----------------------------------------------------------------------------- %packages @gnome-desktop @core @base @base-x @printing @development-tools emacs kexec-tools fipscheck xorg-x11-server-Xnest xorg-x11-server-Xvfb #Packages Located in Workstation Folder *** Install can not find any of these ?? bison doxygen gcc-c++ subversion zlib-devel freetype-devel libxml2-devel Thanks in advance, -Ed

• OpenSSL force client to use specific protocol

  - by Ex Umbris

  When subversion attempts to connect to an https URL, the underlying protocol library (openssl) attempts to start the secure protocol negotiation at the most basic level, plain SSL. Unfortunately, I have to connect to a server that requires SSL3 or TLS1, and refuses to respond to SSL or SSL2. I’ve done some troubleshooting using s_client and confirmed that if I let s_client start with the default protocol the server never responds to the CLIENT HELLO: $ openssl s_client -connect server.domain.com:443 CONNECTED(00000003) write:errno=104 --- no peer certificate available --- No client certificate CA names sent --- SSL handshake has read 0 bytes and written 320 bytes --- New, (NONE), Cipher is (NONE) Secure Renegotiation IS NOT supported Compression: NONE Expansion: NONE --- Watching this in Wireshark I see: Client Server -------syn----------> <------ack----------- ---CLIENT HELLO-----> <------ack----------- [60 second pause] <------rst----------- If I tell s_client to use ssl2 the server immediately closes the connection. Only ssl3 and tls1 work. Is there any way to configure openssl to skip SSL and SSL2, and start the negotiation with TLS or SSL3? I've found the OpenSSL config file, but that seems to control only certificate generation.

• Finding the current user authenticated by basic auth (Apache)

  - by jtd

  When you log in through a basic auth page, is the username you authenticated as stored anywhere (on the server or client machine), maybe in an environment variable? Background: I have a common web administration page for an e-mail server and I'd like to know who is doing what. When a user successfully logs in via basic auth, I somehow want to be able to identify them and log their actions. So each time a request is submitted, I can write to a log file. The basic format would be: $username ran a $function against $useraccount so if a user changed someone's permissions, eg: Admin-Bob ran a permission change against User-Scott So if errors occur, I can easily trace back in the log file what actions lead to the cause. I tried checking the %ENV hash to no avail, any Ideas? I don't really want to get into PHP-like sessions, because that would mean scrapping my basic auth, which gives me a fine degree of control already. If I have to code something with sessions, I'd need to implement a system to block users after maximum tries and so on, which I don't really want to code. I think this is better geared towards serverfault because it pertains to Apache moreso than the programming language. Sessions can be done in a myriad of languages.

• Mail-Merge on Steroids: Can Word 2003 do this?

  - by richardtallent

  I have a huge report to put together, made up of over 1,000 smaller, nearly-identical reports. Each report includes: General 1:1 information (basic mail-merge stuff) Lots of text, some of which may need to be disabled or have alternate text based on a boolean field. A few embedded images, preferably loaded via HTTP URL, but if they have to be on the a file system thing I can do that. (Filenames will be provided as a field in the data source.) Fortunately, all images are roughly the same size/shape. Several 1:m tables with a few fields apiece. The kicker is the master/child tables. I've seen examples for Word 2000 for doing this by left-joining the master and child table and using some IF/THEN logic to know whether to jump to the next master record. But in my case, I have several of these subtables, so that approach won't really work. So, can Word 2003 handle arbitrary master/child tables? If so, how? If not, I considered InfoPath, but I haven't used it before, and it seems to be made for data entry, not long formatted reports. I'm a software developer, so I could always hack something together with a massive VBA macro, or generating the report in HTML on the web server (where the data is coming from anyway). But I'm hoping Word will work without such gymnastics, since it will give the ultimate users of the report template better control over formatting and making minor changes.

• windows xp cannot access admin share

  - by barlop

  I have 3 systems. A,B,Compx all on xp. but comps A and B have an issue with Compx. Compx has network shares I can access. I can do \\compx and get some. But I cannot access the admin share c$ \\compx\c$ gives a login prompt, and I can't get any user/pass to work. I looked at permissions but don't see an issue. Nevertheless, I will describe what I see in the permissions. In the security tab of C, I have Administrators,creator owner,everyone,bob,system,users (6 things there) "creator owner" has nothing ticked, I can't seem to change that. If I tick so they all get ticked, and click apply, 2.5min and it's completed its opration and they all untick. Though this isn't the root of the problem. Since I get the same in the share I can access. In advanced, I see those 6 things, Administrators,creator owner,everyone,bob,system,users (6 things there) all "full control" all are "this folder, subfolders and files".. except creator owner, which is just subfolders and files only I look at the properties for the share I can see. looks the same, except in security..advanced, double clicking any of them the boxes are all ticked but greyed. That's not the problem though since I can access that share. So, I don't know what the problem is.

• Windows - Decrypt encrypted file when user account is destroyed

  - by dc2

  I have a Virtual Machine running on my Windows Server 2008 computer that originally was received by me encryped, as the builder of the VM did it on a MAC, which decrypts files by default. I never thought to decrypt these files, as they automatically 'decrypt' when you have permission over them, so the VM has been running for over a year despite the encryption. I just upgraded my computer to Domain Controller (dcpromo.exe). Now when I try to access/run the VM, I can't because I don't have permission to decrypt the files as that was on another logon (local administrator) and now I am the domain administrator. Apparently the local admin is totally nuked when you upgrade to domain controller. I have tried EVERYTHING - taking ownership of the files, which works. Doesn't do anything for me. Adding full control to everyone on the files. I go to File Properties Advanced Details (under encryption) Users who can access this file. The only user is administrator@localcomputername, and there is a cert number. I try adding a new cert, I don't have permission. I don't have permission to: Decrypt the file (access is denied). Copy the file (to another computer) - access denied. I am totally stumped and this VM is a production machine and needs to get up right now. Does anyone have any ideas?

• What can prevent a Server 2008 machine accessing its OWN UNC shares?

  - by Simon

  I need to set up a UNC share for my hosted dedicated server to access a share on itself. Unfortunately TFS requires a UNC share. I am on a Windows Server 2008 Standard SP2 64bit dedicated server behind a PIX 501 firewall hosted with GoDaddy. I just cannot get the server to access itself and get this error: Windows cannot access \\SERVER\SHARE Check the spelling of the name.. etc. I've found numerous questions about this but no answer to my problem. Server 2008 Standard x64 SP2 Workgroup - not domain Windows Firewall is off Computer browser service is on I am trying to access \\MYMACHINE\TFS-BUILDS by typing in - or double clicking. Neither works. Machine has single network card Filesharing wizard says share was ok Share was showing under 'Computer management' Permissions are set to 'everyone' full control No obvious errors in eventlog Reboot didn't fix it Unfortunately I cannot try to access other shares in or out of this machine because it is a hosted dedicated server and the only machine behind a hardware firewall. The only thing left i can think of is that the hardware firewall needs to be configured. I don't think it is this because we have a 2003 Server machine behind a different hardware firewall and that one works fine. What on earth is left?!

• Questions about explorer.exe

  - by nmuntz

  Hi, I was given by my company a laptop with Windows XP Professional in Spanish. I would like to translate it to English, since I really DISLIKE to use localized versions of programs. I have read about Windows MUI packs, however you MUST have Windows XP Pro in English in order to translate it to other language, you can't translate it TO English from other language. Since reinstalling the OS using a Win XP CD in english is not an option (don't have the license nor the CD, and don't have domain privileges to rejoin my computer to the domain), I was wondering what are the essential files that contain localized strings of text. I was doing some research, and apparently explorer.exe has many of the Windows Error Messages and other strings. Will replacing my original explorer.exe with one from Windows XP in English be enough (and work) for having a "basic" english version of windows? Im mainly interested in having error messages, start menu, and the control panel in english. Also, does it HAVE to be the same version as the Service Pack im running? Besides explorer.exe are there any other essential files that i should try to get and replace? Do you see any "dangers" in replacing this files with english version ones? Thanks in advance for your help.

• I just got a virus 6 mins ago, how? Situation.

  - by acidzombie24

  -Edit- for the people who say it isn't a virus. Norton does detect it as a virus, an icon was placed on my system tray and rkpg.exe is in my C: which was placed 6 min ago around the time my computer rebooted on its own causing me to lose data :@. Situation I on Windows XP, behind a Linksys router, I don't have DMZ on so nothing should be connecting to me. I had Firefox, MSN and Visual Studio opened. With C# I programmed a quick application to scan some pages with Internet Explorer. The site it was scanning was deviantART (which is pretty trustworthy), I doubt any banners there would hold a virus. I went to a suspicious site called freetxt.com but that was on Firefox and it didn't load the site. With an extra check I ping it and got this message "Ping request could not find host freetxt.com." The virus seems to be called braviax. Right now it brought up a message saying my computer may be infected? How on earth did it get in? I don't have uTorrent installed or any torrent or p2p applications. Nothing is installed on my computer that I haven't installed before and I know the exact time it installed because I see rkpg.exe on my C drive and my computer restarted on its own around the same time. For the previous 30 minutes actually the previous hour all I did was talk on MSN, not click any links (I went to freetxt on my own) and had that Internet Explorer thing running (which I programmed). How did it get in? I really doubt it came from a banner on deviantART and installed when I loaded the page with the webbrowser-control so something else may have happened? Is there any system defaults I should turn off? I have remote assistance off but even if it was on I shouldn't be infected due to the router not forwarding any ports?

• "Error 5: Access denied" when installing programs with UAC turned off

  - by Aero

  I'm having some trouble installing msysgit 1.7.3.1preview on Windows 7 Home Premium. I downloaded the setup file from the Google Code and then ran it. Upon running, I got the following error: I have tried downloading and running different older versions of msysgit with no luck. For the record, I have administrative privileges and there are no other user accounts on this Windows machine. Any help would be greatly appreciated. Thanks. UPDATE: I have managed to semi-fix this problem. I turned on User Account Control back to the default setting and and then ran the setup file as an administrator. I successfully managed to install Git. However, this means I have to keep UAC turned on whenever I want to install a new program (I realised that it persists over all programs; not just Git). So it's quite a nuisance. If anybody knows how I could keep UAC disabled whilst still being able to install programs without running their setup files as an administrator, I would be eternally grateful. UPDATE: I have changed the question title to better suit the new situation.

• Application that will identify percentage of your system disk bandwidth used on a user-application by user-application basis?

  - by Warren P

  I always (subjectively) feel my computer is far too slow (however fast it is), and so I'm always looking for ways to measure and understand what my computer is actually doing, that is making it seem "slow" to me. It has been my observation that my software-developer workload is most often disk-bound (I am waiting for Disk I/O) more than CPU bound. What has made it worse, is that I am using a corporate PC that has in-memory active-scanning anti-virus software that I do not have control over, and also some IT department mandated services that seem to suck up a lot of available hard-disk bandwidth. The best tool I have seen (in Windows 7) is the Resource Monitor which I usually acess from the button in the task Manager. The disk IO page, however, seems to label Disk Activity at a very low level (for example, showing the Volume Shadow Storage, which is flushing information obviously written by something ELSE other than VSS itself, and then writes to Pagefile.sys, which are obviously due to Virtual Memory faults in some application). What I would like to know is if a utility exists that can add up all direct disk input and output by user-level process, or find the process or service that caused VM or VSS activity. In that way, I hope, you could establish a real idea of how much of your computer's precious disk subsystem bandwidth is attributable to a particular application. here's a scenario: MyApp.exe writes 100k/s and reads 100k/s directly. VSS ends up writing another 100k/s. pagefaults caused inside MyApp.exe cause another 100k/s of writes. So the total "cost" of MyApp.exe running, during a period of time (let's say 1 second) is 400k/s, whereas you can only directly observe half of that, in Resource Monitor. Is there a smarter disk-IO watching piece of software I can use?

• Extend Linux Desktop to another X Windows Display

  - by unknown (google)

  Hello, I am a long time Linux user of the Xinerama and other technologies for extending a desktop to multiple monitors. However when I travel with my laptop I miss the multi-monitor support I enjoy at home. Recently I acquired a second laptop for a low price. Both laptops are running Fedora (versions 10 and 11 respectively). I use Gnome as my primary desktop environment. I know about synergy. I use synergy all the time to control the screen of other Windows / Linux systems I use. I would like to know, can I sit both my primary and secondary laptops together and achieve a Xinerama-like extended desktop environment? Ideally I would like to start a GNOME session on my primary laptop. And then start a X-Windows Desktop on my secondary laptop and extend my primary laptop's desktop onto it. I would like to be able to move Windows from the primary desktop to the secondary laptop desktop. Would I need to use synergy to do this with some other bit of X-Windows technology? Or is there X-Windows technology that will do all this for me? I am familiar with X Windows ability to display applications remotely. I am also familiar with Nomachine's NoX.

• Revamping an old and unstable office IT-solution using Windows Server and OpenVPN

  - by cmbrnt

  I've been given the cumbersome task to totally redo the IT-infrastructure for a customer's office. They are currently running Windows XP all over, with one computer acting as a file server with no control over which users have access to which files, and so on. To top it off, this file server also functions as a workstation, which means it gets rebooted every time the user notices some sluggish behavior or experiences problems with flash games. To say the least, this isn't working for them. Now - I've got a very slim budget, but I need to set up a new server, and I wish to run Windows Server 2008 on it. I also need the ability to access the network remotely via VPN. Would it be a good idea to install VMware ESXi 4.1 onto the new server, and then run Windows Server 2008 as well as a separate Debian install for openvpn on it? I don't like the Domain Controller for the future AD to also run a VPN-server, because of stability issues when something goes to hell with either of them. There will be no redundancy though. However, I'm not sure if there is something to gain by installing a VPN solution on the Windows Server itself, when it comes to accessing file shares on the network via VPN. I don't know how to enable users logging in via the VPN to access the remote files, since they will be accessing the network from their own home computers (which is indeed a really bad idea, but this is what I've got to work with). They won't be logged in to the windows Domain, but rather their home workgroups. I need to be able to grant access to files in certain directories based on the logged in AD-user, but every computer won't necessarily be configured to log into the domain. I'm not sure how to explain this in a good way, but I'd be happy to clarify if somethings not clear. Any help would be great, because I've got a feeling that I can't do this without introducing a bunch of costly new rules when it comes to their IT-solution. I'd rather leave that untouched and go on my merry way to the next assignment.

• glassfish timeout

  - by Stefano

  Environment: Windows 2008 Server Edition Netbeans 6.7.1 Glassfish 2.1 Apache 2.2.15 for win32 Original problem (almost fixed): The HTTP/1.1 GET method to send data fails if I wait for more than 30 seconds. What I did: I added to the http.conf file of Apache these lines: # # Timeout: The number of seconds before receives and sends time out. # Timeout 9000 # # KeepAlive: Whether or not to allow persistent connections (more than # one request per connection). Set to "Off" to deactivate. # KeepAlive On I went to the Glassfish panel (localhost:4848) and in Configuration HTTP services and I put: Timeout request: 9000 seconds (it was 30) Standby time: -1 (it was 30 seconds) Problem: I am not able to put for glassfish a timeout bigger than 2 minutes to send a GET method. I found this article about glassfish settings, but i'm not able to find WHERE I should put those parameters, and if they could work. Can anybody help try to set this timeout to a higher limit? Maybe it's even a different setting? New tried solution: I went to the glassfish panel control, and to Configuration Subprocesses "Thread-pool-name" and changed the idle timeout from 120 seconds to 1200 seconds. Then I restarted the glassfish service (both from the administrative tools and from asadmin), but still it waits 120 seconds to go idle. I even tried restarting the whole server, still no results. Maybe some setting in postgres? Or the connection of netbeans to postgres through glassfish?

• 2012 R2 services will not start after promotion to Domain Controller

  - by Cybersylum

  Having a peculiar issue promoting a Windows 2012 R2 server in a domain at 2003 domain/forest functional level. Built a new 2012 R2 server, added the following software (labtech, appassure, eset A/V, & Teamviewer). It activated and appeared to be working fine. I added the Active Directory Domain Services role, and completed the configuration (Domain/Forest Prep, and DC promotion). All appeared to go well. I rebooted the server, and that's where the peculiar stuff began. I noticed the server indicated it needed activated again; but would not accept the key. I verified the key was good. That's when I noticed the Software Protection service (as well as many other core services - Base Filtering engine, DHCP client, firewall, etc) would not start. The error message for all of them was "Access Denied". I called MS, and they wanted to troubleshoot at a service level. Their fix was to use procmon and identify the resource that needed permissions (registry key, file or folder) and add "everyone" with full control). That got the services to start; but the problem re-appeared after a reboot. Thinking the issue might have been with the anti-virus package during the promotion process, I rebuilt the DCs from scratch and removed the metadata from AD (as I could not demote the machines "rpc server unavailble"). I tried to promote the newly built machines again. The only changes to the brand new machines being critical updates. Again the promotion appeared to work fine; but upon reboot (and a long wait to allow replication to occur) similar problems began to re-appear. I have verified that the schema updates are correct (schema version is 69 - for Windows 2012 R2). I am not finding much about this issue through my own searches, so I thought I would post this to see if anyone else has seen anything similar...

• windows xp cannot access admin share

  - by barlop

  I have 3 systems. A,B,Compx all on xp. but comps A and B have an issue with Compx. Compx has network shares I can access. I can do \\compx and get some. But I cannot access the admin share c$ \\compx\c$ gives a login prompt, and I can't get any user/pass to work. I looked at permissions but don't see an issue. Nevertheless, I will describe what I see in the permissions. In the security tab of C, I have Administrators,creator owner,everyone,bob,system,users (6 things there) "creator owner" has nothing ticked, I can't seem to change that. If I tick so they all get ticked, and click apply, 2.5min and it's completed its opration and they all untick. Though this isn't the root of the problem. Since I get the same in the share I can access. In advanced, I see those 6 things, Administrators,creator owner,everyone,bob,system,users (6 things there) all "full control" all are "this folder, subfolders and files".. except creator owner, which is just subfolders and files only I look at the properties for the share I can see. looks the same, except in security..advanced, double clicking any of them the boxes are all ticked but greyed. That's not the problem though since I can access that share. So, I don't know what the problem is.

• Desktop appliciations are unable to launch my browser in Windows 8 [migrated]

  - by Alex Ford

  I have a fresh copy of Windows 8 Pro installed from MSDN. I have Google Chrome installed (stable channel) and it is set as my default browser. I even went into Control Panel Default Programs to ensure that Chrome had all its defaults. When other desktop applications try to launch my browser they always fail. For example, while trying to install the Android SDK for Windows the installer accurately detected that I did not have the JDK installed. It provides a friendly button to visit java.oracle.com. When pressing this button, nothing happens at all. You can see that here: http://youtu.be/XXL8GhuWWg0 If it were only that application that was having issues I wouldn't think anything of it but I have been encountering similar issues all over the place. Probably the most irritating one is when visual studio has updates; clicking the update button does nothing. http://www.youtube.com/watch?v=zwd1mn3TId0 You can see in that screencast that Visual Studio is not able to launch the browser no matter what I click. The update button doesn't do anything and neither do the two links in the update's description. Any suggestions? I'm assuming it's a Windows issue since it is happening in multiple applications.

• Single application through OpenVPN tunnel (Debian Lenny)

  - by user14124

  I'm using Debian Lenny and I want to tunnel rtorrent only through a OpenVPN tunnel. I have a tunnel running, the config file looks like this: client dev tun proto udp remote openvpn.xxx.com 1194 resolv-retry infinite nobind persist-key persist-tun ca /etc/openvpn/xxx/keys/ca.crt cert /etc/openvpn/xxx/keys/client.crt key /etc/openvpn/xxx/keys/client.key tls-auth /etc/openvpn/xxx/keys/tls.key 1 ns-cert-type server comp-lzo verb 3 auth-user-pass script-security 3 reneg-sec 0 My idea is that I could run a sockd proxy internally that redirects traffic to the openvpn tunnel. I could use the *nix "proxifier" application "tsocks" to make it possible for rtorrent to connect through that proxy (as rtorrent doesn't support proxies). I have trouble configuring sockd as my IP inside the VPN changes every time I connect. This is a config file someone said would help: http://ircpimps.org/sockd.conf As my IP changes at each connect I don't know what to put in that config file. I have no control over the host side config file. Any help wanted. Any other method is very welcome.

• 3 Monitor PCI-e Graphics card on Linux (without tremendous pain)?

  - by N Rahl

  As we are all painfully aware, the only way to get multiple monitors AND compositing (Compiz) on Linux is to use a single graphics card that can drive both (or in my case all three) screens. I bought a Radeon 5750 specifically because it claims to able to drive 3 monitors. I can plug in 3 monitors (2 DVI, 1 HDMI) and the Catalyst Control Center shows all 3, but only 2 can be enabled at a time. The exact message is: The current settings cannot be applied. Possible issues may include: - Display(s) cannot be enabled. - Setting(s) cannot be applied due to insufficient video memory. So I'm going to assume that either the 5750 doesn't support 3 monitors, OR, more likely, ATI couldn't be bothered to add that support to their Linux drivers. So this is a multipart question: First, can anyone suggest a PCI Express Graphics card that can run 3 screens on linux without tremendous pain? I'm looking for something where you install the driver and all three screens "just work". Does such a card exist? Second, if you have a 5750, have you been able to get it to do 3 monitors? I'm running Ubuntu 10.04 at the moment.
