Ubuntu 18 and Dota 2 error

John D K -

Dota 2 can be installed on Ubuntu 18 or Linux Mint 18 with several mouse clicks. First you need to install steam from the Software Center and then download Dota 2. It is working without problems but sometimes could disconnect you or to hang up. In order to kill current running Dota and start new one you need to:

  • Change the windows by:
    • ALT + TAB
  • Open Linux Terminal by:
    • CTRL + ALT + T
  • Run command
top

the output will be similar to:

  • The you can kill Dota process by executing:
sudo kill <pid>
sudo kill -9 <pid>

Or in this case:

sudo kill 25062

or the more powerful

sudo kill -9 25062

to kill all process that you can with your user do(in case that above commands is not working):

killall -ursa

To detect which is the process running the Dota 2.

This problem is causing the mouse to not be active outside Dota 2. So you are not able to use anything else except your keyboard.
