  • 13.04 Temp Save, rt3290, Kernel downgrade

    - by user170534
    It's kind of a multiplying but I didn't wanted to open more than one topics. I'd have a fresh install of Ubuntu with tlp configured and using acpi_call to keep 7670M turned off. I was a short time arch user and with openbox and firefox it was about 60 to 70 degrees; wanted to turn to a stable release just for this reason. acpitz-virtual-0 Adapter: Virtual device temp1: +50.0°C radeon-pci-0100 Adapter: PCI adapter temp1: -128.0°C coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +56.0°C (high = +87.0°C, crit = +105.0°C) Core 0: +54.0°C (high = +87.0°C, crit = +105.0°C) Core 1: +55.0°C (high = +87.0°C, crit = +105.0°C) The temperature is not seriously high yet can be lower. Another issue is my wifi card, rt3290: The rt2800pci module is fine and all that but the download performance is pretty bad alongside of annoying signal range and the prop. driver gives a conf error about some specific rt2860 code and integrales in pci_dev file. If I blank off the error making variables, module loads but the driver is unused. Since the driver is old, I was thinking of downgrading the kernel of raring to 3.7 or may be 3.6. Should &-or can I?

  • Sound not working with Ubuntu 12.10 clean install

    Did a clean install of Ubuntu 12.10 from 12.04 and the sound is not working now. In 12.04 it worked out of the box.

  • Wireless (Broadcom) just stopped working after putting machine to sleep!

    - by tommed
    Had the wireless working on my Dell Studio 15 for months now (Ubuntu 10.04 64bit, now 10.10 64bit). But I shut the lid this morning, which put the machine to sleep; when I openend it again the wireless would no longer connect to anything :'( I rebooted the machine, but that didn't help. I then did ifconfig eth1 {down,up}, but that didn't help, then I did iwconfig eth1 power {down,on}, but that didn't work. So I uninstalled the wireless driver (Broadcom STA) from additional drivers (reboot in the middle), but it still won't work anymore!! This is the trace from daemon.log, looks like it is a driver issue? Nov 28 12:26:39 ulap NetworkManager[1218]: (eth1): supplicant connection state: disconnected - scanning Nov 28 12:26:39 ulap NetworkManager[1218]: (eth1): supplicant connection state: scanning - disconnected Nov 28 12:26:45 ulap NetworkManager[1218]: (eth1): supplicant connection state: disconnected - scanning Nov 28 12:26:50 ulap wpa_supplicant[1295]: Trying to associate with MY_MAC_CODE (SSID='MY_WIRESS_SSID' freq=2417 MHz) Nov 28 12:26:50 ulap wpa_supplicant[1295]: Association request to the driver failed Nov 28 12:26:50 ulap NetworkManager[1218]: (eth1): supplicant connection state: scanning - associating Nov 28 12:26:51 ulap wpa_supplicant[1295]: Associated with MY_MAC_CODE Nov 28 12:26:51 ulap NetworkManager[1218]: (eth1): supplicant connection state: associating - associated Nov 28 12:27:01 ulap wpa_supplicant[1295]: Authentication with MY_MAC_CODE timed out.

It had been working fine up until now?! Even ran update-manager, but there wasn't any changes to the wireless drivers (or any related networking areas). Running the most up-to-date version of 10.10 x64. My android phone and other devices are still working on the wireless.

  • Is my graphics card in use or not?

    - by Lindhe94
    I have a Samsung Series 7 NP730U3E which is running Ubuntu Gnome 13.10. This computer have an Intel Core i5 3337U an AMD Radeon HD 8570M on the inside. Ubuntu 13.10 is said to have driver support for this graphics card, but I am not sure whether or not this is the case.

  • After upgrade to 12.04 wireless keeps dropping on BCM4312

    I know there are plenty of questions very similar to these, but I've tried practically everything and it still isn't working.

  • Slight stuttering when moving windows in fresh 12.04 install

    - by Konsolkongen
    Installed Ubuntu 12.04 today and my problem is that when I'm moving the windows around my screen it doesn't feel smooth at all. Usually I can fix this by changing the refresh rate to 60Hz, but this time it doesn't help. My graphics card is a Nvidia GTX 560Ti and I've tried both the 295.40, 295.45 and 304.43 (which I'm currently using) but neither has resolved my problem. I searched around a bit and tried changing the refresh-rate using compizconfig-settings-manager and xrandr. No change using CCSM, but when I tried xrandr I got this reply: konsolkongen@konsolkongen-desktop:~$ xrandr -r 60Rate 60.0 Hz not available for this size - which is nonsense of course. This is what my xorg.conf file looks like: # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 295.33 (buildd@allspice) Fri Mar 30 15:25:24 UTC 2012 Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" Option "Xinerama" "0" EndSection Section "Files" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" # HorizSync source: edid, VertRefresh source: edid Identifier "Monitor0" VendorName "Unknown" ModelName "Samsung SyncMaster" HorizSync 30.0 - 81.0 VertRefresh 56.0 - 75.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce GTX 560 Ti" EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 Option "TwinView" "0" Option "TwinViewXineramaInfoOrder" "DFP-0" Option "metamodes" "DFP-0: 1680x1050_60 +0+0" SubSection "Display" Depth 24 EndSubSection EndSection Any help would be greatly appreciated, my obsession with video quality can't stand stuttering like this.

  • Ubuntu 13.10. After login, no desktop displayed. Two Nvidia Graphics Cards, Four Monitors

    - by jmerkow
    I am working on an issue with my Ubuntu 13.10 installation. I am attempting to get 4 monitors up and running but I am having some trouble. So far, I installed and updated to the latest NVIDIA drivers (331.20). Initially X would not start (after installation) so I replaced my xorg.conf with xorg.conf.failsafe. This fixed that problem, but then I tried to enable the other 2 monitors (other video card) and xorg fails to start once again (after I login there is no desktop). I am fairly new to linux but I am not a complete beginner, but I'm not comfortable poking around too much on my own to troubleshoot yet.... lspci -nn | grep VGA: 03:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF110 [GeForce GTX 570 Rev. 2] [10de:1086] (rev a1) 05:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF110 [GeForce GTX 580] [10de:1080] (rev a1) It seems that the nvidia-settings tool does not result in a good xorg.conf file.

  • Ubuntu 12.10 and nVidia drivers don't like each other?

    - by mingos
    I decided to upgrade both my computers from Precise to Quantal. What a mistake that was. My laptop has a nVidia GT 330M card, while the desktop has an nVidia 9600 GT. In both cases everything goes great as long as I use the Nouveau driver (ugh!). Can't really play games (Amnesia... and hoping for Steam Beta participation...), even though it's OK for work. Now, ever since 9.04 or so, I just installed nvidia-current and all just worked. Since 12.10, after installing nVidia drivers, Unity won't start at all (hangs with only the wallpaper displayed, no cursor or widgets), Gnome Shell is permanently in fallback mode. Now, I have tried on both computers, with multiple clean installs on Ubuntu (two separate downloads, just in case), one from Ubuntu Gnome Remix. And additionally, Fedora 17, which seems to suffer from the same issue. Tried all nVidia driver suggestions available in Software Sources, and even compiled the drivers myself. I tried several versions of the driver to exclude an issue with the newest one. In my frustration, I have switched to Windows (which, ironically, "just works" with my hardware), but still hold a twin OS configuration on the desktop and would like to use Ubuntu again. So, can anyone point me to where the issue might lie?

  • Problem video nvidia ubuntu 12.04

    - by dragonov7
    I just did a fresh install of ubuntu 12.04 on my PC (Dell precision 370) but the video is not working as it should. Problems: When I log in to unity 3D I get a transparent bar (where the firefox, libre office, etc icons are) but I can see the tooltips when I put my mouse over where the icons are, I can see the top toolbar with no problem and I see just white on the rest of the desktop! When I log in using unity 2D I see the left bar cut in half (so I can't see the trash icon that is at the botton), the toolbar at the top shows OK and the desktop show OK but with some apps. For example, if I open a terminal and maximize it, it will only show just where the left toolbar "cuts". But if I open firefox it will open fine. Config: My PC comes with a nvidia quadro nvs 280 and I see that by default ubuntu is using the nouveau driver. Workarounds tried: I tried uninstalling the nouveau driver and the desktop works fine but I can use only unity 2D. I tried installing the nvidia-173 drivers using synaptic but I get "Could not apply changes! Fix broken packages first". I go to "Edit - Fix Broken packages" and I get the error: "E: Unable to correct problem, you have held broken packages.E: Error, PkgProblemResolver::Resolve generated breakes, this may be caused by held packages.E:Unable to correct dependencies" Output of lspci: 01:00.0 VGA compatible controller: NVIDIA Corporation NV37GL [Quadro PCI-E Series] (rev a2) Any idea so as to what I should do? Thanks in advance for any help. PS: Ah, the nvidia-173 driver was working fine on ubuntu 10.04.

  • Can't open DDMS

    - by Emerald214

  • Localization in ASP.NET MVC 2 using ModelMetadata

    - by rajbk
    This post uses an MVC 2 RTM application inside VS 2010 that is targeting the .NET Framework 4. .NET 4 DataAnnotations comes with a new Display attribute that has several properties including specifying the value that is used for display in the UI and a ResourceType. Unfortunately, this attribute is new and is not supported in MVC 2 RTM. The good news is it will be supported and is currently available in the MVC Futures release. The steps to get this working are shown below: Download the MVC futures library   Add a reference to the Microsoft.Web.MVC.AspNet4 dll.   Add a folder in your MVC project where you will store the resx files   Open the resx file and change “Access Modifier” to “Public”. This allows the resources to accessible from other assemblies. Internaly, it changes the “Custom Tool” used to generate the code behind from  ResXFileCodeGenerator to “PublicResXFileCodeGenerator”    Add your localized strings in the resx.   Register the new ModelMetadataProvider protected void Application_Start() { AreaRegistration.RegisterAllAreas();   RegisterRoutes(RouteTable.Routes);   //Add this ModelMetadataProviders.Current = new DataAnnotations4ModelMetadataProvider(); DataAnnotations4ModelValidatorProvider.RegisterProvider(); }   Use the Display attribute in your Model public class Employee { [Display(Name="ID")] public int ID { get; set; }   [Display(ResourceType = typeof(Common), Name="Name")] public string Name { get; set; } } Use the new HTML UI Helpers in your strongly typed view: <%: Html.EditorForModel() %> <%: Html.EditorFor(m => m) %> <%: Html.LabelFor(m => m.Name) %> ..and you are good to go. Adventure is out there!

  • Configure 27" 2560x1440 for a monitor with corrupt EDID

    - by Aras
    I am trying to get a monitor work with my Ubuntu laptop. The monitor is this cheap 27" Korean monitors which has a 2560x1440 resolution -- and nothing else. Here are some specifications of this monitor: 2560x1440 @60Hz Only one dual link DVI-D input -- no other input port (no HDMI or display port) no OSD no scalar reports corrupt EDID does 2560x1440 @60Hz, did I say that already? Anyways, the monitor works beautifully with my Ubuntu desktop which has an nVidia card with DVI output. However, I am having problem using this monitor with my laptop. After some searching around I found a few posts suggesting to use an active adaptor for mini display port, so I went and bought a mini display to dual link DVI-D adaptor.. When using this adaptor the monitor is recognized by nvidia-settings tool but with incorrect resolution information. As you can see the monitor is incorrectly recognized and there are no other resolution available to set. This post on ubuntu forums and this other post on overclock both suggest that the monitor is reporting corrupt EDID file. I have tried following their instructions, but so far I have not been able to display any image on the monitor from my laptop. The laptop I am using is an ASUS G75VW with a 1920x1080 screen. It has a VGA, an HDMI 1.4a, and a mini display port. The graphic card is an nvidia gforce gtx 660M with 2GB dedicated memory. I am running Ubuntu 12.10 on here which I upgrade from 12.04 a few weeks ago. As I said I have tried several suggestions, including specifying Modeline in xorg.conf and also linking to EDID files I found from those forum posts above. However, I am not sure if the EDID files I found are suitable for my monitor. I think the solution to my problem consist of obtaining the EDID file of my monitor and then fixing it and modifying xorg.conf to force nvidia driver to load the correct resolution. However, I am not sure what steps I need to take to do this. Here is the part of sudo xrandr --prop output that is related to this monitor: DP-1 connected 800x600+1920+0 (normal left inverted right x axis y axis) 0mm x 0mm SignalFormat: DisplayPort supported: DisplayPort ConnectorType: DisplayPort ConnectorNumber: 3 (0x00000003) _ConnectorLocation: 3 (0x00000003) 800x600 60.3*+ I was expecting to see the EDID file in this output as was mentioned in this post, but it is not there. After several hours of tweaking X configurations, I decided it was time to ask for help here. I would really appreciate if someone with experience regarding EDID and X configuration could give me a hand to solve this issue.

  • Using DisplayTag library, I want to have the currently selected row have a unique custom class using

    - by Mary
    I have been trying to figure out how to highlight the selected row in a table. In my jsp I have jsp scriplet that can get access to the id of the row the displaytag library is creating. I want to compare it to the the id of the current row selected by the user ${currentNoteId}. Right now if the row id = 849 (hardcoded) the class "currentClass" is added to just that row of the table. I need to change the 849 for the {$currentNoteId} and I don't know how to do it. I am using java, Spring MVC. The jsp: ... <% request.setAttribute("dyndecorator", new org.displaytag.decorator.TableDecorator() { public String addRowClass() { edu.ilstu.ais.advisorApps.business.Note row = (edu.ilstu.ais.advisorApps.business.Note)getCurrentRowObject(); String rowId = row.getId(); if ( rowId.equals("849") ) { return "currentClass"; } return null; } }); %> <c:set var="currentNoteId" value="${studentNotes.currentNote.id}"/> ... <display:table id="noteTable" name="${ studentNotes.studentList }" pagesize="20" requestURI="notesView.form.html" decorator="dyndecorator"> <display:column title="Select" class="yui-button-match" href="/notesView.form.html" paramId="note.id" paramProperty="id"> <input type="button" class="yui-button-match2" name="select" value="Select"/> </display:column> <display:column property="userName" title="Created By" sortable="true"/> <display:column property="createDate" title="Created On" sortable="true" format="{0,date,MM/dd/yy hh:mm:ss a}"/> <display:column property="detail" title="Detail" sortable="true"/> </display:table> ... This could also get done using javascript and that might be best, but the documentation suggested this so I thought I would try it. I cannot find an example anywhere using the addRowClass() unless the comparison is to a field already in the row (a dollar amount is used in the documentation example) or hardcoded in like the "849" id. Thanks for any help you can provide.

  • Selenium Webdriver (FirefoxDriver)

    - by Samareri
    Hey all, I'm using Selenium Webdriver to do some robottesting. Since some functions appear to only work in Firefox, I'm obligated to use Firefoxdriver. Now and then, something weird happens. Starting up te driver driver = new FirefoxDriver(); driver.get(URL); gets firefox to startup but not to go to the specified url. The strange thing is that it works on another computer with the same preferences set in Firefox. I solved this problem once by changing to another version of firefox, but this time this doesn't do the trick for me, it did however worked for the other developers. Yes, the error started for all developers on the same time, same day... My first question is: is it a firefox problem or Webdriver problem. Second question: how is it possible that it works on other pc's? Any help would be very appreciated Thanks Error: org.openqa.selenium.WebDriverException: Could not parse "".

  • Connection Error using NHibernate 3.0 with Oracle

    - by Olu Lawrence
    I'm new to NHibernate. My first attempt is to configure and establish connection to Oracle 11.1g using ODP. For this test, I use a test fixture, but I get the following error: Inner exception: "Object reference not set to an instance of an object." Outer exception: Could not create the driver from NHibernate.Driver.OracleDataClientDriver. The test script is shown below: using IBCService.Models; using NHibernate.Cfg; using NHibernate.Tool.hbm2ddl; using NUnit.Framework; namespace IBCService.Tests { [TestFixture] public class GenerateSchema_Fixture { [Test] public void Can_generate_schema() { var cfg = new Configuration(); cfg.Configure(); cfg.AddAssembly(typeof(Product).Assembly); var fac = new SchemaExport(cfg); fac.Execute(false, true, false); } } } The exception occurs at the last line: fac.Execute(false, true, false); The NHibernate config is shown: <?xml version="1.0" encoding="utf-8"?> <!-- This config use Oracle Data Provider (ODP.NET) --> <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2" > <session-factory name="IBCService.Tests"> <property name="connection.driver_class"> NHibernate.Driver.OracleDataClientDriver </property> <property name="connection.connection_string"> User ID=TEST;Password=test;Data Source=//RAND23:1521/RAND.PREVALENT.COM </property> <property name="connection.provider"> NHibernate.Connection.DriverConnectionProvider </property> <property name="show_sql">false</property> <property name="dialect">NHibernate.Dialect.Oracle10gDialect</property> <property name="query.substitutions"> true 1, false 0, yes 'Y', no 'N' </property> <property name="proxyfactory.factory_class"> NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu </property> </session-factory> </hibernate-configuration> Now, if I change the NHibernate.Driver.OracleDataClientDriver to NHibernate.Driver.OracleClientDriver (Microsoft provider for Oracle), the test succeed. Once switched back to Oracle provider, whichever version, the test fails with the error stated earlier. I've spent 3 days already trying to figure out what is not in order without success. I hope someone out there could provide useful info on what I am doing wrong.

  • Have problems designing input and output for a calculator app

    - by zoul
    Hello! I am writing a button calculator. I have the code split into model, view and a controller. The model knows nothing about formatting, it is only concerned with numbers. All formatting is done in the view. The model gets its input as keypresses, each keypress is a part of an enum: typedef enum { kButtonUnknown = 0, kButtonMemoryClear = 100, kButtonMemoryPlus = 112, kButtonMemoryMinus = 109, kButtonMemoryRecall = 114, kButtonClear = 99, … }; When the user presses a button (say 1), the model receives a button code (kButtonNum1), adds the corresponding number to a string input buffer ("1") and updates the numeric output value (1.0). The controller then passes the numeric output value to the view that formats it (1). This is all plain, simple and clean, but does not really work. The problem is that when user enters a part of a number (say 0.00, going to enter 0.001), the input does not survive the way through model to view and the display says 0 instead of 0.00. I know why this happens ("0.00"::string parses to 0::double and that gets formatted as 0). What I don’t know is how to design the calculator so that the code stays clean and simple and the numbers will show up on screen exactly as the user types them. I’ve already come with some kind of solution, but that’s essentially a hack and breaks the beautiful and simple flow from the calculator model to the display. Ideas? Current solution keeps track of the calculator state. If the calculator is building a number, I take the calculator input buffer (a string) and directly set the display contents (also a string). Otherwise I take the proper path, ie. take the numeric calculator output, pass it to the view as a double and the view uses its internal formatter to create a string for the display. Example input: input | display | mode ------+---------+------------ 0 | 0 | from string 0. | 0. | from string 0.0 | 0.0 | from string 0.0+ | 0 | from number This is ugly. (1) The calculator has to expose its input buffer and state. (2) The view has to expose its display and allow setting its contents directly using a string. (3) I have to duplicate some of the formatting code to format the string I got from the calculator input buffer. If user enters 12345.000, I have to display 12,345.000 and therefore I’ve got to have a commification code for strings. Yuck.

    hi m very new to java and Linux i have a code which is taken from examples of jcuda.the code is following import jcuda.CUDA; import jcuda.driver.CUdevprop; import jcuda.driver.types.CUdevice; public class EnumDevices { public static void main(String args[]) { //Init CUDA Driver CUDA cuda = new CUDA(true); int count = cuda.getDeviceCount(); System.out.println("Total number of devices: " + count); for (int i = 0; i < count; i++) { CUdevice dev = cuda.getDevice(i); String name = cuda.getDeviceName(dev); System.out.println("Name: " + name); int version[] = cuda.getDeviceComputeCapability(dev); System.out.println("Version: " + String.format("%d.%d", version[0], version[1])); CUdevprop prop = cuda.getDeviceProperties(dev); System.out.println("Clock rate: " + prop.clockRate + " MHz"); System.out.println("Threads per block: " + prop.maxThreadsPerBlock); } } } I'm using Ubuntu as my operating system i compiled it with following command 1:-javac -cp /home/manish.yadav/Desktop/JCuda-All-0.3.2-bin-linux-x86_64 EnumDevices i got following error error: Class names, 'EnumDevices', are only accepted if annotation processing is explicitly requested 1 error i don't know what is the meaning of this error.what should i do to compile the program than i changed the compiling option which is javac -cp /home/manish.yadav/Desktop/JCuda-All-0.3.2-bin-linux-x86_64 EnumDevices.java than i got following error EnumDevices.java:36: clockRate is not public in jcuda.driver.CUdevprop; cannot be accessed from outside package System.out.println("Clock rate: " + prop.clockRate + " MHz"); ^ EnumDevices.java:37: maxThreadsPerBlock is not public in jcuda.driver.CUdevprop; cannot be accessed from outside package System.out.println("Threads per block: " + prop.maxThreadsPerBlock); ^ 2 errors Now I'm completely confused i don't know what to do? how to compile this program ? how to install the jcuda package or how to use it ? how to use package which have only jar files and .so files and the jar files don't having manifest file ? please help me

  • show/hide html table columns using css

    - by Art Peterson
    I want to display a basic html table with controls to toggle showing/hiding of additional columns: <table id="mytable"> <tr> <th>Column 1</th> <th class="col1">1a</th> <th class="col1">1b</th> <th>Column 2</th> <th class="col2">2a</th> <th class="col2">2b</th> </tr> <tr> <td>100</td> <td class="col1">40</td> <td class="col1">60</td> <td>200</td> <td class="col2">110</td> <td class="col2">90</td> </tr> </table> So Column 1 and Column 2 will be the only columns displayed by default - but when you click on the Column 1 I want 1a and 1b to toggle, and same with Column 2 with 2a and 2b. I may end up with more columns and lots of rows - so any javascript looping approaches have been too slow to work with when I tested. The only approach that seems to be fast enough is to set up some css like this: table.hide1 .col1 { display: none; } table.hide2 .col2 { display: none; } table.hide3 .col3 { display: none; } table.show1 .col1 { display: table-cell; } table.show2 .col2 { display: table-cell; } table.show3 .col3 { display: table-cell; } And then set up onClick function calls on the table header cells that will trigger a toggle - and determine which css class to set "mytable" to that will create the toggle effect that I'm looking for. Is there an easy way to set this up so that the code can work for n # of columns?

  • What is the best way to create related types at runtime?

    - by SniperSmiley
    How do I determine the type of a class that is related to another class at runtime? I have figured out a solution, the only problem is that I ended up having to use a define that has to be used in all of the derived classes. Is there a simpler way to do this that doesn't need the define or a copy paste? Things to note: both the class and the related class will always have their respective base class, the different classes can share a related class, and as in the example I would like the control class to own the view. #include <iostream> #include <string> class model; class view { public: view( model *m ) {} virtual std::string display() { return "view"; } }; #define RELATED_CLASS(RELATED)\ typedef RELATED relatedType;\ virtual relatedType*createRelated(){\ return new relatedType(this);} class model { public: RELATED_CLASS(view) model() {} }; class otherView : public view { public: otherView( model *m ) : view(m) {} std::string display() { return "otherView"; } }; class otherModel : public model { public: RELATED_CLASS(otherView) otherModel() {} }; class control { public: control( model *m ) : m_(m), v_( m->createRelated() ) {} ~control() { delete v_; } std::string display() { return v_->display(); } model *m_; view *v_; }; int main( void ) { model m; otherModel om; model *pm = &om; control c1( &m ); control c2( &om ); control c3( pm ); std::cout << c1.display() << std::endl; std::cout << c2.display() << std::endl; std::cout << c3.display() << std::endl; }
