Run Dolphin as root (OpenSUSE 12.1)

I know that LINUX users prefer the terminal. However, sometimes you just need (at least I need) a file manager to do the job. So, to run Dolphin as root open a terminal window and type:
     kdesu dbus-launch dolphin

Indy 10, Lazarus 1 (OpenSUSE 12.1)

After hours of attempts to install Indy 10 for Linux on Lazarus 1.0, here's the solution:

1) Download Indy 10.2.0.3 from here

    http://www.indyproject.org/Sockets/fpc/index.EN.aspx

2) Extract from tar.gz file (copy file to Documents>right click>Extract here [...]       autodetect subfolder) This will create a directory Indy-10.2.0.3

3) Open Lazarus>Package>Open package file. 

4) Select Indy-10.2.0.3/lazarus/indylaz.lpk

5) Select Options

6) Go to Compiler options>Paths

7) On the first line (Other unit files ...) add:  ../fpc On Windows it also required to add lib\i386-win32

8) Now select Use>Install. If it's not working, try Compile then Use>Install.

I tried to create a TCP server and more problems appeared. Here we go:

- In order to compile the project I had to add the path to Indy units in Project>Project Options>Compile Options>Paths>Other units file... If  ../fpc does not solve your problem (like in step 7 from above), you must specify the path to the fpc directory from your package

- I received some error about using threads. The solution was to add a new line into project1.lpr, so it should look like this:

uses
  {$DEFINE UseCThreads}
  {$IFDEF UNIX}{$IFDEF UseCThreads}
  cthreads,
  {$ENDIF}{$ENDIF}
  Interfaces, // this includes the LCL widgetset
  Forms, Unit1, lnetvisual 

- The TCP server must be forced to use IPv4, othervise it will say that the port or addres is blocked or in use. Before activating the component I added:
   server1.Bindings.Add.IPVersion := Id_IPv4;
  Now you can do:
   server1.Active:=true;
Of course, now it said that Id_IPv4 is not defined. The solution is to add in the implementation area:
   uses idglobal;

[UPDATE]
Newer versions of Indy are available. See my latest posts for installation of Indy 10.6 

VM Virtual Box (OpenSUSE 12.1/12.2)

OpenSUSE 12.2

    After installing the VM Virtual Box version 4.2.6, it won't start. In  terminal it displayed the following error: "Failed to open the X display"
    The solution was to recompile the VirtualBox kernel. The following packages are needed:
           kernel-devel
         kernel-source
         gcc
     Than VirtualBox kernel can be recompiled:
         sudo /etc/init.d/vboxdrv setup


OpenSUSE 12.1
 
    After installing the VM Virtual Box version 4.2.0, when I tried to add an existing VM, I came across the following error: “Could not start process Cannot talk to klauncher: Not connected to D-Bus server”.

    The solution for now is to downgrade the D-Bus packages to version 1.5.8.2.1.2/3. To do this, step-by-step:

1. Open YaST>Software Management
2. Search for “dbus”
3. On “dbus-1”, “dbus-1-devel”, “d-bus-1-devel-doc” and “dbus-1-x11” select the option to use version 1.5.8.2.1.2/3. To do this, select the package and on the lower part of the screen you will find the tab “Versions”. There you can select the version you want to be used.
