## Installing KDE |
|
|
`sudo apt update` |
|
|
|
|
|
`sudo apt install kubuntu-desktop` |
|
|
|
|
|
Select SDDM as display manager during setup |
|
|
|
|
|
`sudo apt install lightdm` |
|
|
|
|
|
During installation, select lightdm as default display manager using arrow keys |
|
|
|
|
|
Edit the lightdm configuration as follows: |
|
|
|
|
|
`sudo nano /etc/lightdm/lightdm.conf` |
|
|
|
|
|
Add the following text |
|
|
``` |
|
|
[Seat:*] |
|
|
user-session=plasma |
|
|
|
|
|
[LightDM] |
|
|
start-default-seat=false |
|
|
|
|
|
[XDMCPServer] |
|
|
enabled=true |
|
|
port=177 |
|
|
``` |
|
|
Save and exit by pressing ctrl + o and then ctrl + x |
|
|
|
|
|
## Setting up x server |
|
|
Download and install this software for windows: |
|
|
|
|
|
https://sourceforge.net/projects/vcxsrv/ |
|
|
|
|
|
## Launch Desktop |
|
|
- From windows open the **XLaunch** program |
|
|
- Select the `One window without titlebar` option and click `Next` |
|
|
- Selct `Open session via XDMCP` and click next |
|
|
- In your ubuntu terminal you need to get the ip address of the wsl2 instance: |
|
|
- Run: `sudo apt install net-tools` |
|
|
- Run: `ifconfig eth0 | grep inet` |
|
|
- The ip address will be listed after the `inet` item and usually looks like 172.xxx.xxx.xxx |
|
|
- Copy the ip address above and paste into the text box next to `Connect to host` in the XLaunch window and click `next` |
|
|
- Modify the default settings to uncheck `Native opengl` and check `Disable access control` |
|
|
- Click `Next` |
|
|
- Click `Save configuration` and save the file to your desktop and name the file whatever you want |
|
|
- **VITALLY IMPORTANT: When you first run VcXSrv (or XLaunch) you’ll get a Windows Firewall popup. You will need to allow it to accept connections on both the PRIVATE and PUBLIC networks. If you don’t allow PUBLIC networks you will not get a connection as the WSL Virtual Network is considered to be PUBLIC** |
|
|
- Click `Finish` |
|
|
