SuperTuxKart blocks keyboard input when running SuperTuxKart on a TTY

[searinminecraft]

Description

When running SuperTuxKart (like starting a server) on a TTY, SuperTuxKart completely blocks keyboard input. Which means I can't switch to another tty (like tty7, where the desktop is), or even type server commands in the network console. Not even CTRL+ALT+DELETE and the magic SysRq key combinations work and I'm forced to reboot my system by pressing the power button or triggering an ACPI shutdown. The only workaround is to switch to another tty immediately while SuperTuxKart is loading, then switching back to that tty.

Steps to reproduce

1. When on a desktop environment, switch to another tty by pressing CTRL + ALT + F6 and log in with any user.
2. Run a SuperTuxKart server (it doesn't have to be a WAN server). For example: supertuxkart --lan-server=Test --no-graphics --network-console. (Or you can just run SuperTuxKart with no graphics with supertuxkart --no-graphics)

Configuration

STK release version: Compiled from source

STK Source (PPA, distribution package, official binary, etc.): Arch Linux

Try remove the --network-console

[searinminecraft]

Try remove the --network-console

No change. It still blocks keyboard input

[Benau]

try rebuild supertuxkart with cmake .. -DSERVER_ONLY=ON

[Benau]

I don't think it's possible to make it working with (or worth the effort) ordinary supertuxkart binary (probably some libraries it uses misbehave in console)

[searinminecraft]

try rebuild supertuxkart with cmake .. -DSERVER_ONLY=ON

ok i will try that..

[searinminecraft]

ok. i compiled the latest git with that argument and it seems that it no longer blocks keyboard input. (i made sure i did a git pull so it would have the latest code). but i need to make sure it really doesnt block input anymore.

[Benau]

assuming it's working for you
