Title:
screen flickering and tearing kwin nouveau kubuntu 16.04
Status in xorg package in Ubuntu:
Expired
Bug description:
The bug I see on my Dell D830 (8GB RAM, Nvidia G86M [Quadro NVS 140M]
(rev a1)) with nouveau driver using Kubuntu 16.04.
After login everything seems to work fine for roughly 2 minutes. After
that flickering and tearing starts (when moving windows around with
the mouse) and gets more intense until the screen is full of "color-
blobs" (which means: one cannot see anything anymore). Starting a
flash movie in Firefox provokes immediate tearing and flickering.
Restarting the kwin compositor helps - for another 2 minutes, then the
whole problem starts to catch on momentum again. I tried everything
mentioned here:
http://askubuntu.com/questions/672007/flickering-in-kde-plasma-5-4
the only thing that helps for a longer period of time is turning off
compositing completely.
I am unsure where to further look for the problem: Is it kwin? xorg?
nouveau? All of them? Whatever? The logs I checked (xorg, syslog,
dmesg etc.) contain nothing that I can make sense of.
I'd appreciate any hint to where (and: what) to look (for) and which
more specific information to collect ...
