Hello Artiom,

thank you for bringing this up, but you have entered unfortunally the wrong section. This here is the question section for presenting questions from community to community people for answering. All on good will.

What you need is bugreporting.

For short:

1.Press ALT and F2



direct followed by the software name(exactly please)

Alternativly you can use

ubuntu-bug -w

and click on the open program that makes trouble.

3.See apport starting

4.Please describe your problem in a exact way, that makes it a developer which is not familiar with the softeware you use to reproduce the bug(thing of explanation to a beginner - step by step).

Please do this procedure for every software separated. One error one bugreport.

For the long story how to report a bug(recommend to read):


After this please close this here as solved(recommend) or when you think it makes sense than link this here with the option on this side to the bugreport.

Thank you in advance

Not a hardware issue but a software issue
