  • Ubuntu 9.10: switch in KVM, mouse is detected but not usable immediately

    - by CarlF
    I use a KVM switch to jump between my tower and laptop, both placed on my desk. With Ubuntu 9.04 this worked perfectly. In 9.10, when I switch to the tower, then back to the laptop, the mouse is detected (as shown by /var/log/messages) but moving it has no effect. If I use Ctrl-Alt-F1 to switch to the TTY, then Alt-F7 back to Xorg, the mouse starts working. The tower is running Windows 7, but that shouldn't matter. Sometimes, but not other times, the USB keyboard on the KVM switch is also not usable and I have to use the laptop's built-in keyboard to switch to the TTY. The laptop has two monitors, the built-in and an external. It's (obviously) the external panel that is attached via the KVM switch. Any suggestions? Report to Canonical as a bug?

  • How to open a page in Chrome from the command line, in a new tab or an existing tab as appropriate?

    - by MattH
    I'm looking for a way to open a given page in Google Chrome from the command line, with the following behaviour: If the given page is already open in a tab, navigate to that tab If the given page is not already open in a tab, open the page in a new tab and show that tab Currently when I open a URL from the command line (e.g. using "open http://godzillahaiku.tumblr.com" on Mac OS X), Chrome will always open the URL in a new tab. I end up with lots of duplicate tabs as a result, which is a minor annoyance. I'm looking for a solution that works on Mac OS X, but a non-OS specific solution would be preferable. I'd consider writing a Chrome extension for this if there's no existing solution.

  • How to install GNOME desktop from DVD on CentOS 6 using the command line?

    - by alwbtc
    I have installed CentOS 6 in Virtualbox. Although I have chosen to install General Purpose GNOME Desktop, the GNOME desktop does not start. All I get is a black and white text prompt. I would like to know how I can install GNOME Desktop from the CentOS DVD. How do I mount the DVD image? How do I install GNOME desktop from command line? If I already have the GNOME Desktop installed, why doesn't it start? How can I check from command line that I have GNOME installled? This virtual machine does not have internet connection, that's why I want to install the GNOME Desktop from DVD.

  • Windows command line ZIP extraction with checksum or similar ?

    - by Alan B
    What I need to do, at the command line, is: Extract the contents of a a ZIP archive. Change an arbitrary number of the extracted files. Repeat step 1, but because it is a huge archive, only extract the archived copies of the files changed in step 2 which is much faster. Ideally the extraction in step 3 would do something like a checksum on the files on disk and only extract those where the file in the archive has a different checksum. Or maybe compare the date changed stamp on the disk file. At the minute I use pkzipc.exe which is the command-line version of PkZip. I can't see a way to do it with this though. You can extract files from the archive that are newer than the disk files, but what I want is the opposite of that in a sense.

  • Windows 7: how can I add an IP range in the "route" command?

    - by KeyStroke
    Hi, I'm using two network connections, and I tried using the "route" command so that when I access a specific internal IP on my LAN, it would use connection 1, anything else would go normally through connection 2 (which doesn't have access to my LAN). The problem is I have a bunch of internal IP's that I need to access, and the "route" command doesn't seem to allow me to add an IP range instead of specific IP. And connection 1 doesn't have internet access, so I can't use it as my default connection. Any idea how this can be solved? Your help is appreciated

  • Is there an RSM replacement in Windows 7? (to eject USB and Firewire devices from command line)

    - by Jay
    I know Windows XP and previous had an rsm.exe file in the <root>\windows\system32 folder that could be used to manage media. I used this command in batch files and from the command line to eject external disks (iPod, CF cardreader, etc.). This utility appears not to be included in Windows 7, and I wonder if there is some replacement utility that will allow the same thing. I've been unable to find any such thing. I'm aware of the 3rd party utilities; this question is only about what is included with Windows 7.

  • Is A Managed Switch With VLAN Support Required

    - by Justin
    Hello, I am wondering if I need to buy a switch which is managed (VLAN support) for my configuration, or will a cheaper unmanaged switch work? I have servers with two NICS each. The first NIC is public and the second NIC is private. The router will plug into the switch port 1 let's say (public). Then server 1 public plugs into port 2 on the switch, and sever 1 private plugs into port 3 on the switch. The public interface is: 192.168.X.X / 255.255.0.0 and the private interface is 10.0.X.X / 255.255.0.0. So looks like: ** SWITCH ** Port Device Network 1 Router/Firewall 192.168.X.X 2 Server 1 Public 192.168.X.X 3 Server 1 Private 10.0.X.X 4 Server 2 Public 192.168.X.X 5 Server 2 Private 10.0.X.X 6 Server 3 Public 192.168.X.X 7 Server 3 Private 10.0.X.X Thanks.

  • How to install GRUB command-line tools on OSX?

    - by beakr
    I need access to grub-mkrescue for a project I'm working on. I know that the GRUB command-line tools come builtin to Linux, but how do I get them on OSX? Is there a package? Is it built into the system somewhere? Is there an installer? CLARIFICATION: The question is not about installing GRUB as a bootloader on the Mac. The question is about installing the GRUB command line tools to do things like create bootable disk images of other operating systems.

  • How do I open a program via the command prompt in Windows 8?

    - by Ahmadul Hoq
    Suppose I have a program named any_program.exe and my operating system drive is C:. The location of the program is D:\Any_Folder\any_program.exe How do I start/execute that program via command prompt in Windows 8? I have tried the command line START any_program.exe, but it shows me an error that Windows cannot find 'any_program.exe'. Make sure you typed the name correctly, and then try again. By the way, it worked perfectly in Windows 7. And, if I type START notepad.exe or START firefox.exe (Firefox is not installed in C: drive), it works in Windows 8.

  • Resolution changes when using switch

    - by Edward D
    So, the "real" resolution of my monitor is 1024x768. That's what I'd use on my docked Windows laptop, and what I'd use on my Xubuntu desktop connected directly. When I connect a switch, to switch between the two, however, the ubuntu machine's resolution changes. Everything's still proportional, and it still thinks it's doing 1024x768, but the icons and fonts appear larger. Not 800x600 larger, but still big. When I used Xubuntu Precise, I created an xorg.conf file to set a resolution of 1280x1024 which made it look the way it does without the switch ... as a workaround. When I upgraded to Trusty, I lost this. I tried to re-create it, but doesn't seem to load my file. Ideally, I'd like to correct the original problem, but I'd settle for being able to up the resolution. I searched for a while, and tried to do it, but I'm giving up ... please help me out.

  • Implementing a switch statement based on user input

    - by Dave Voyles
    I'm trying to delay the time it takes for the main menu screen to pop up after a user has won / lost a match. As it stands, the game immediately displays a message stating "you won / lost" and waits for 6 seconds before loading the menu screen. I would also like players to have the ability to press a key to advance to the menu screen immediately but thus far my switch statement doesn't seem to do the trick. I've included the switch statement, along with my (theoretical) inputs. What could I be doing wrong here? if (gamestate == GameStates.End) switch (input.IsMenuDown(ControllingPlayer)) { case true: ScreenManager.AddScreen(new MainMenuScreen(), null); // Draws the MainMenuScreen break; case false: if (screenLoadDelay > 0) { screenLoadDelay -= gameTime.ElapsedGameTime.TotalSeconds; } ScreenManager.AddScreen(new MainMenuScreen(), null); // Draws the MainMenuScreen break; } /// <summary> /// Checks for a "menu down" input action. /// The controllingPlayer parameter specifies which player to read /// input for. If this is null, it will accept input from any player. /// </summary> public bool IsMenuDown(PlayerIndex? controllingPlayer) { PlayerIndex playerIndex; return IsNewKeyPress(Keys.Down, controllingPlayer, out playerIndex) || IsNewButtonPress(Buttons.DPadDown, controllingPlayer, out playerIndex) || IsNewButtonPress(Buttons.LeftThumbstickDown, controllingPlayer, out playerIndex); }

  • How to switch off? [closed]

    - by Xophmeister
    While I've programmed software for many years, I've only recently started doing so professionally and have noticed a bit of a problematic pattern. I hope this is the best place to pose such a question, as I am interested in others' experiences and solutions... Writing software is, by its nature, a cerebral exercise. When coding for my own sake, I would do so until I was satisfied; even if that meant going all night. Now I'm coding in exchange for goods and services, on projects that are inherently uninteresting to me, I want to 'switch off' when it's time to go home. Maybe you consider that to be a 'bad attitude', but I just don't feel that whatever I'm working on is worth caring about after-hours. Besides, my employer doesn't exactly have the infrastructure required to make out-of-office changes; I can't just clone a repo and even remote login is a PITA. Anyway, the problem I'm experiencing is that, while I'm not particularly overworked or stressed, if I'm faced with a problem, my brain will work on a solution. Generally, it won't give up. Hence I can't switch off and, sometimes, the problem or the solution is significant enough that it disrupts my sleep. While, paradoxically, this doesn't seem to affect my coding ability, it can have a profound impact of the rest of my life. I get increasingly low as I get tired. So far, the best solutions I've found are writing little notes on the matter (and, say, e-mailing them back to my work address) and exercise. Neither of these can switch me off entirely and, as the week progresses, exercise especially becomes untenable due to tiredness. TL;DR How can you stop from being a coding zombie?

  • Concatenating several .mp3 files into one .mp3

    - by Bakhtiyor
    As it was suggested here I am using cat command to concatenate several .mp3 files into one .mp3 file. Imagine, I have following .mp3 files in the current folder: 001001.mp3 001002.mp3 001003.mp3 001004.mp3 001005.mp3 or, like this: 096001.mp3 096002.mp3 096003.mp3 096004.mp3 I need to concatenate these .mp3 files in there ascending sequence, i.e. 001001.mp3+001002.mp3+001003.mp3+etc. In order to join these .mp3 files into one I am executing following command in the current folder: cat *.mp3 > final.mp3 I tested the final .mp3 file and it is what I am expected, but I need to be sure that above command picks files in there ascending sequence. Can I be sure that above command always concatenates files in the ascending sequence? Thank you Sir!

  • chromium-browser --proxy-server debugging

    - by user3678068
    Many places online have pointed out to configure chromium proxy via command can be achieve with the following line chromium-browser --proxy-server=[username]:[password]@[host]:[port] but I got this result on every request. Here's the output in the command line right after executing the previous command. (They do not appear to be relevant. There are no new command line output when I try to visit a page) libGL error: failed to authenticate magic 30 libGL error: failed to load driver: vboxvideo ATTENTION: default value of option force_s3tc_enable overridden by environment. [29551:29551:0606/160459:ERROR:sandbox_linux.cc(268)] InitializeSandbox() called with multiple threads in process gpu-process I have double checked that the proxy credential works with the foxyproxy chrome plugin. What else can I try to figure this out? [Edit] Going to chrome://net-internals/#proxy and reading "Effective proxy settings" if I do chromium-browser with no flags, I get Use DIRECT connections. Source: GSETTINGS if chromium-browser --proxy-server=[host]:[port], I get a message box requesting to login, and under "Effective proxy settings": Proxy server: [host]:[port] if chromium-browser --proxy-server=[user]:[pass]@[host]:[port], "Effective proxy settings" shows: Use DIRECT connections

  • How to check the process is already running or not

    - by TechGuru
    I want to check the particular process in already running or not. I refereed this Q&A. But I didn't get any specific solution. Following is the example that I tried: I have created abc.sh file and run this script on background, like sh abc.sh &. Now this file is running on background and I fire the ps aux | grep "abc" command. Following is the output of this command: prakash 3594 0.0 0.0 4388 820 pts/0 S+ 16:44 0:00 grep --color=auto abc After that I stop the abc.sh running script and fire the same command ps aux | grep "abc" command. But I am getting same output like: prakash 3594 0.0 0.0 4388 820 pts/0 S+ 16:44 0:00 grep --color=auto abc Is there any other way to find the process is running or not?

  • Terminal exits program before able to accept Hashcat EULA

    - by Fluffaduff
    I'm trying to play around with hashcat,just using the examples included with the program, but before the command can run it requires me to accept the EULA. Instead of me being able to enter 'YES', the terminal appears to end the process immediately. Whenever I try to accept the EULA I get the expected 'YES: Command not found.' I don't think I'm using the command wrong, but I also don't know whats happening. http://i.imgur.com/ClloeK6.png

  • How to set MANPATH without overriding defaults?

    - by balki
    I have added extra directories to $PATH by exporting PATH=/my/dirs:$PATH But I am not sure if I should do the same to MANPATH. Because default MANPATH is empty yet man command works. I found a command called manpath and its manual says If $MANPATH is set, manpath will simply display its contents and issue a warning.. Does this mean setting MANPATH is not the right way to add directories for man command to search for manual pages?

  • Alternative to | more to display error results page by page

    - by Lane
    The command psql -d template_postgis2 -f /usr/share/postgresql/9.1/contrib/postgis-2.1/postgis.sql returns a list of errors that is too long to be displayed by scrolling up to the beginning of the error. I tried the same command with "| more" and "| less" added up at the end of the command but it does not display the message page by page as it should. I also tried to put the output in a file with "> file.txt" but I do not get in this new file what is displayed on the screen!! I don't understand why. I guess i can't do this with a psql command?? Is there any other way to get all the error message? Thanks for your help!

  • Weird execution of ruby/git executables in Windows [migrated]

    - by Frexuz
    Something strange has happened. I can't run some command line executables in Windows anymore. Steps: Open cmd Run an executable, such as ruby -v or git -h When I do that, a new command prompt opens, running that command (I think, it's too fast to see), and instantly closes again. I've managed to print screen the new command prompt, and it shows that it's running inside this path: C:\Documents and Settings\Administrator\Local Settings\Temp\3582-490 Inside this folder, is the executable I'm tring to run. If I run ruby, then ruby.exe is in there. If I run git, then git.exe is in there. And it's always emptying the folder in between, so there is always just one .exe file

  • How to wire 20 computers and 20 phones and 1 server into LAN?

    - by John Smith
    I have currently 3 switches Two Netgear JFS524 with 24 slots, One Belkin with 16 slots. Server DSL Internet Router. Main question is how to connect switches together, two Netgear's are next to each other, yet one is about 100 feet away and holds about 5 computer and 5 phones. If i connect them with only 1 wire will that limit bandwidth? e.g. all 23 computers will be limited to speed of one CAT5e cable? If i connect switches with 2 cables will this give speed boost? What's the ideal scenario should i just move the third switch next to other two? Will the speed of computer connected to white switch be same as computer connected to top switch? Will moving white switch right next top switch and having 16 wires comming 100 feet instead of 1 wire comming 100 feet make it faster? EDIT 1: I actually have NETGEAR ProSafe GS105 Gigabit switch its only has 4 ports in it though, you think i can have use of it in current setup? Like connect all 3 switches and server into it and keep internet router and phone server on one of the slower switches EDIT 2: Everyone mention gigabit switches, but will they do any difference with 10/100 network cards? I then have to use gigabit cards in every computer too? I could in server perhaps, but users will be 10/100

  • will heavy network traffic affect other connections on HP ProCurve V1810-48G?

    - by nn4l
    I have a HP ProCurve V1810-48G switch with a few servers connected to it (everything in one rack). The switch is practically in its default configuration. During copying of a few hundred GByte of data from server_a to server_b (using tar cf - data | ssh server_b 'cd myhome; tar xf -'), essentially saturating the network capacity between those two servers, I noticed network related error messages on the console of server_c - as if server_c is no longer able to send/receive traffic to server_d. After canceling the copy command everything was normal again. I would understand this if the network connection would use a shared resource, for example if server_a and server_c are in one datacenter, server_b and server_d are in another datacenter and both datacenters are connected with a 100 MBit line. But all of the mentioned servers are connected to the same switch and are located in the same IP network. I always thought that a connection between two servers on one switch will not affect any other server connected to the switch. It is also possible that the network related error messages are caused by something else - but I can't risk a network problem for any other system on this switch. Please advise.

  • WPF Calling a custom command on a custom control (from a viewmodel?)

    - by user190615
    I want to take a snap of the visual tree of a custom wpf control when the user clicks a button in a toolbar. The control is bound to a viewmodel. I have a BitmapSource dp in the custom control holding the snapped image which is bound to a property on my VM. The BitmapSource dp on the control is updated via a custom command on the control. I've tied the toolbar button's command to call the controls command which updates the BitmapSource. Now the problem is the end result I want is when the user clicks the button, the control updates its image and then the vm offers to save this image. I cant wrap my mind around an mvvm way of doing this. One inelegant solution is that control fires an event after the image is updated which is routed to the viewmodel as a command(command behavior) but then if i want to do something else with the image on some other button click, all the commands bound to the events will fire. All thoughts appreciated. EDIT The command on the control is a RoutedCommand and the commands in my vm are Prism delegate commands.
