[Bug 1509556] Re: Kubuntu Wily upgrade screen glitch with 4.2 kernel

 

I'm also experiencing Intel Graphics issues on two different systems
running Kubuntu Wily.  One is a Baytrail Chromebook, and the other is a
desktop system with a Haswell Pentium processor.  In both systems, using
the OpenGL Kwin compositors results in all manners of graphical glitches
and system instabilities.  The only solution so far has been to revert
to XRender. Note that the desktop system was upgraded from Kubuntu
Vivid, which ran fine.

Title:
  Kubuntu Wily upgrade screen glitch with  4.2 kernel

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  On  recent  update   from  15.04   to  15.10, the new  4.2  kernel  is  associated   with    graphics  instability after  a  few  seconds of   GUI  use   with  mouse   and   keyboard making  the  GUI  unusable.  See  another  person's  same  experience   with  intel   graphics   here:  
  askubuntu.com/questions/688649/kubuntu-wily-upgrade-screen-glitch

  Downgrading  to the  last   15.04    kernel   solves  my  issue.
   
  See  result  of   ubuntu-bug linux   from  the  terminal attached.
