Root missing $DISPLAY hacks

Consider following scenario:

> (user) echo $DISPLAY
:1
> (user) echo $XAUTHORITY
/run/user/1000/gdm/Xauthority
> su
> echo $DISPLAY
:1
> echo $XAUTHORITY
/run/user/1000/gdm/Xauthority
> su -
> echo $DISPLAY

> echo $XAUTHORITY

>

I have display :1, yours may vary.

When (user) or su are requesting $DISPLAY and it is set but when not inheriting from (user) $DISPLAY:

• something happened with /root/.Xauthority?

  • su -

  • ln -s /home/(user)/.Xauthority /root/.Xauthority

  • su -

  • add to /root/.profile:

    • export DISPLAY=:1; on a new line

Can be easier to see autocomplete of $DISPLAY/etc. by using fish instead of sh/bash

Make Steam games work

(Overwatch/Apex/etc)

• Steam -> Compatibility -> Enable Proton Edge/Experimental (top) / Hotfix (bottom)

• If game doesn't load (but you have launched it at least once) or if you cannot Alt+Tab

  • https://www.youtube.com/watch?v=Q_xMmWt6sEY&t=2m50s
    • each game on Steam has appId which you can see on a website
  • Install protontricks
    • launch it via GUI: protontricks --gui
      • as a user, not as su because steam is installed for a user
      • select GameName - appId of a game you want to change
        • for a game to appear on this list you have to launch your game at least once via Steam -> right click game -> settings -> Compatibility -> [+] -> Proton
      • choose top launch Select the default wineprefix -> Run winecfg -> Compatibility -> set Resolution to your monitor
        • next time game launches it would go through this wincfg
