===== STEAM REINSTALL / RESET / CLEAN =====

===== KOMPILACE SOURCE SDK MOD =====
To build the Source SDK 2013 on Linux you will need the Steam runtime. Install it using these instructions:
Download it here
<code bash>
$ tar xvf steam-runtime-sdk_latest.tar.xz
$ cd steam-runtime-sdk_<version> # (replacing <version> with the version you just unpacked.)
$ ./setup.sh # (Pick your architecture and debug/release preferences and then answer Y to everything else.)
$ ./shell.sh --arch=i386
$ make -f game_<gamename>_linux32.mak
</code>

At this point you should have client.so and 
server.so files to load with the Source SDK Base 2013 of your choice. More instructions on 
using the Steam runtime can be found in README.txt in the installed runtime directory.

Lze pouzit pokud v dane hre nefunguji napriklad videa. Uprava je platna vzdy pouze pro konkretni hru / aplikaci. Bohuzel zatim nelze jednoduse cely proton setup obnovit, viz https://github.com/ValveSoftware/steam-for-linux/issues/5687

Jde vlastne pouze o wrapper nad starymi dobrymi [[https://wiki.winehq.org/Winetricks|winetricks]] takze lze pouzit vsechny stejne volby, kuprikladu i stary dobry //--help//. Jak tedy na to:

  - vypneme danou hru / aplikaci
  - zjistime Steam //APPID// dane hry / aplikace<code bash>
$ protontricks -s <jmeno>
</code>napr.:<code bash>
$ protontricks -s TheRoomThree
Found the following games:
The Room Three (456750)

To run Protontricks for the chosen game, run:
$ protontricks APPID COMMAND

NOTE: A game must be launched at least once before Protontricks can find the game.

^parametr^volitelny^popis^
|VKD3D_CONFIG=no_upload_hvv|x|Game freezes periodically on nvidia 525 driver without the VKD3D_CONFIG=no_upload_hvv argument|
|VKD3D_CONFIG=dxr,dxr11|-|Enables DXR, DXR tier 1.1 support if supported by device|
|PROTON_ENABLE_NVAPI=1|-|Enable the latest NVAPI to report proper nVidia GPU driver versions and GPU capabilities to games.|
|PROTON_ENABLE_NGX_UPDATER=1|-|Enables NGX Core updater for wine / proton|
|PROTON_HIDE_NVIDIA_GPU=0|x|PROTON_HIDE_NVIDIA_GPU used to be required to fix a bug where proton would always report an AMD GPU. This bug has been fixed so the variable should no longer be needed but should be tried if you have issues enabling either DLSS or RTX.|
|PROTON_NO_ESYNC=1|x|Disables eventfd-based synchronization for proton|

===== TROUBLESHOOTING =====
==== Zmizela knihovna / Nema exec opravneni ====
http://www.mameau.com/add-existing-steam-library-folders/

Lze vyresit pres GUI Steamu, ale slozka musi byt prazdna pro opetovne vytvoreni knihovny. Pro obejiti zbytecneho kopirovani muzeme ale knihovnu pridat primo do konfigurace.

  * Vypneme steam
  * V textovem editoru otevreme soubor
<code>
~/.local/share/Steam/config/config.vdf
</code>
  * Doplnime do sekce InstallConfigStore > Software > Valve > Steam polozku BaseInstallFolder_x, kde x je cislo ktere stale roste. Viz priklad.
<code>
"InstallConfigStore"
{
	"Software"
	{
		"Valve"
		{
			"Steam"
			{
				"BaseInstallFolder_1"		"/opt/steam-nenimisto"
				"BaseInstallFolder_2"		"/mnt/steam"
</code>
  * Ulozime a steam zase spustime
