Read before posting - Information to PCSX2 on GNU/Linux

[XXXBold]

This thread contains some hints and troubleshooting how you should proceed whenever you have problems with PCSX2 on GNU/Linux.

Others might point you to this thread because your post is lacking necessary information in order to give you further assistance. Please read through this Text carefully, and modify your original post then.

Some of this points will not apply to all problems, however: Try to provide as much information as you can. This will increase your chance on getting faster/better responses.
 
Basic troubleshooting

• Try to launch PCSX2 from Terminal directly (Don't use shortcuts/Start menu entries etc.) to avoid possible problems with these.
  
• Try to restart with a new PCSX2-configuration (Close PCSX2 when running, backup & delete config in $HOME/.config/PCSX2, re-run First-time wizard)
  
• Verify your Hard- and Software meets the minimum requirements, see here: https://github.com/PCSX2/pcsx2#system-requirements
  

Graphics/Video Troubleshooting

• Can you run other 3D-OpenGL Applications (Games) on your system? If no, it's most likely not an issue with PCSX2.
  

Sound Troubleshooting

• No Sound: Verify your configuration works: Are you able to play other sources like Music, Movies...? If not, solve that first.
  

If troubleshooting doesn't help, and you cannot find a thread already covering your problem, feel free to create a new topic. Include as much as possible from the following.
Make sure to embbed logs/console outputs etc. using the code-format to keep your text better readable.
