If I go to text mode and back to x11, kwin crashes. In some conditions, this happens every time.

Reproducible: Always
Comment 1 Thomas Lübking 2014-07-03 17:59:23 UTC 
crashes in nvidia blob.

-> dmesg | grep NVRM
does it say sth. about unsupported usage of framebuffer console?
Comment 2 Luiz Angelo De Luca 2014-07-03 18:10:16 UTC 
You mean this?

[   13.429210] NVRM: loading NVIDIA UNIX x86_64 Kernel Module  331.79  Sun May 18 03:55:59 PDT 2014

[   34.760233] NVRM: on the primary VGA device. The NVIDIA Linux graphics driver

I'll search how I can disable it. Thanks.
