You need to Install xRDP in ur ubuntu machine the error GTK is a cross-platform widget toolkit for creating graphical user interface.
Follow these steps install xRDP and open in ur windows Machine Via RDC (Remote Desktop Connection) and use Chromium.
Step 1 – Install xRDP
Open Terminal (Crtl+Alt+T) and execute the following commands:
sudo apt-get update
sudo apt-get install xrdp
Step 2 – Install XFCE4 ( Unity doesn't seem to support xRDP in Ubuntu 14.04; although, in Ubuntu 12.04 it was supported ). That's why we install Xfce4.
sudo apt-get install xfce4
Step 3 – Configure xRDP
In this step, we modify two files to make sure xRDP uses Xfce4. First we need to create, or edit, our .xsession file in our home directory. We can either use nano or simply redirect an echo statement (easier):
echo xfce4-session >~/.xsession
The second file we need to edit is the startup file for xRDP, so it will start Xfce4.
sudo nano /etc/xrdp/startwm.sh
The content should look like this (pay attention to the last line and ignore . /etc/X11/Xsession):
if [ -r /etc/default/locale ]; then
export LANG LANGUAGE
Step 4 – Restart xRDP
To make all these changes effective, restart xRDP as such:
sudo service xrdp restart
Testing your xRDP connection
On the computer that will remotely control your Ubuntu machine, start you RDP client. Windows comes standard with a Remote Desktop client (mstsc.exe – you can start it from a command prompt, or find the shortcut to Remote Desktop under Accessories). Or Search 'remote' in start (Windows 7) Or 'remote' in search box in Windows 8.
