libX11 1.1.5 causes qt apps to freeze
Last modified: 2014-06-18 05:11:10 EDT
Description of problem:
LibX11-1.1.5 causes the Mathematica Front-End to freeze after finishing its boot sequence. Suspect the origin of the problem is Qt.
Version-Release number of selected component (if applicable):
Problem fixed by downgrading to 1.1.4
Steps to Reproduce:
1. Start Mathematica
2. Wait 5 sec until the splash screen pops up
Mathematica freezes, the content of the windows stays blank is another window is carried over it
Mathematica should work!
Only Mathematica (the front-end) freezes, not MathKernel (the back-end).
I noticed the same thing happening once with qt-octave but did not have the opportunity to try again with qt-octave. Hence the suscpicion that qt is involved, Mathematica using also qt (although it embeddes its own version).
