Solved Steam does not start correctly

[Voltaire]

I installed linux-steam-utils and everything seems to be configured correctly.
I'm using a gtx 650 and have the correct drivers and libs installed.
Steam won't start and gives the following output.

To me it seems that Warning: failed to set thread priority is the problem. The steam GUI I see is incomplete. This image shows how it looks.

Any help is welcome.

I managed to solve it myself. I had a closer look at the warnings and error messages and tried to find a solution. I couldn't find a solution anywhere that had an effect on this problem.

Then I found the following topic

Steamuxulation redux

I used to play Project Zomboid Build 41 during its development around June-July with linux-steam-utils. With the final release of Build 41, it is no longer playable with the following output (Java-related though it includes the java runtime needed?)...

forums.freebsd.org

The following things were said here
1. For a few weeks now, after some upgrade of Steam itself probably, the steam browser appears all black again, so I cannot even view my library of installed games anymore.
2. Just tried this, and after steam updated, I was getting a blank login screen. I've pulled the latest changes from git, compiled and updated, and now it works. I don't use the linux-steam-utils port, but I assume it's just a matter for time before port and pkg are updated with the latest changes from git, which appear to fix this issue; the store and library are rendering like they normally do.
Hope this helps

I then uninstalled the linux-steam-utils package and I did autoremove. Then I installed it via git and I solved the problems I encountered and now it works.
