Driver allows to play in Half-Life: Alyx without VR on keyboard and mouse. This method allows to complete the game and try out VR mechanics. Some moments will make sweat, but they are passable in this way.
Detailed setup process can be seen in this video.
After installing SteamVR and TrueOpenVR, need to go to the SteamVR state window -> Setup room -> Small room -> Calibrate-> 170cm.
Also must add launch options.
For Steam, go to the game’s properties, click on the launch options and enter +vr_gg_gesture_pull 0. For a regular shortcut, go to the shortcut properties and add the same "C:\Games\Half-Life Alyx\bin\win64\hlvr.exe" +vr_gg_gesture_pull 0.
In the game settings, you need to select "Movement: Smooth" (for smooth walking as in regular games).
Warning! Select the "Headset Window" or press "F7" for the driver to work.
Also do not forget to set the resolution (1920x1080) for full screen mode. You can see how it is configured in more detail here.

• Chapter 5: North star (power off)
First you need to use rotation ("U", "J", "H", "K"), then reset ("Y"), then raise the lever (left and right mouse button + look up or Insert and Home) and lock the controller ("'").
• Chapter 6: the arms Race (lasers)
For lasers, you must use the separate mode ("L"). Move up, down, right and left with the mouse, and move forward and back with the buttons (up, down). Laser clearance can be seen in this video.
• Chapter 7: Jeff (opening the bunker)
This requires training and patience. First you need to lower the lever (grab the lever in the mode of movement of the left controller (left and right mouse button) and move it down ("}")), then turn 2 cells, first you need to pull it up a little and turn it (use the view and the rotation buttons ("U", "J", "H", "K") or "Backspace"), then you only need to lower the last lever down. Grab the lever in the mode of movement of the left hand (left and right mouse buttons), look down and click the button for moving the controllers down ("}"). The entire process of passing this point can be seen in this video.
• Chapter 10: Breaking and entering (battle with the spider)
We grab the weapon with the right controller and direct it towards the spider, higher. Next, in the mode, grab the reload lever and move it up and down, one at a time (by looking at or using the buttons for moving the controllers up and down "{" ,"}", in the mode for moving the left controller, the left and right mouse buttons). It is extremely important to aim the weapon higher to get into the final ball launched by the spider.
• Not enough health
If you are stuck and can't pass one of the hard moments, then you can use the immortality cheat code. To do this, you need to launch the game from the console. Add the launch parameters to the game -allowdebug -vconport 29000 -vcon-console, enter sv_cheats 1 and then god, after which you will be immortal and easily pass the difficult moments. Do not forget to disable the immortality mode after passing a difficult place by entering the god command again.
Also saves are also available to skip difficult moments of the game.
Red screen - switch the focus to the game, press the left mouse button and then switch again to the "Headset window". Also can change the "DebugMode" parameter to true, in the "default.vrsettings" configuration file.
Please read opened and closing issues and carefully read the description. Perhaps your problem already has a solution.
You can stream game play 3D to smartphone, for example, through the application Moonlight (for Nvidia 600 series +) or Trinus.
