Description Matt Z. 2016-11-12 22:08:02 UTC
loaded fresh install of Kubuntu 16.10 on HP Pavilion dv6000 Notebook

Discover crashes every time with a segmentation fault. Sorry, but the "file report" window says debug info is useless.

KDE Plasma: 5.7.5
KDE Frameworks: 5.26.0
Qt Version: 5.6.1
Kernel: 4.8.0-27-generic
OS Type: 64-bit
AMD processor with 2.8 GiB RAM

Graphics Card: NVIDIA C67 (GeForce 7150M / nForce 630M)
Display Driver: nouveau -- resolution 1280x800

Notes:
-- using the nvidia driver causes blank screen at boot (presumably at the login screen)
-- if booting with 'nomodeset', graphics is default vga, and discover does not crash
-- previous version Kubuntu 15.10 worked ok (wish I still had the iso so I could reinstall that)
-- tried reinstalling 16.10, no difference

Doesn't it happen with any other application?
We need more information than that...
Comment 2 Matt Z. 2016-11-14 21:15:52 UTC
well... plasma crashes once in a while too (same thing with the debug report, says it's useless for you). Otherwise, so far other apps seem to work ok, though I haven't used the system that heavily after reloading kubuntu... and I've managed to install updates & other apps ok.

Sorry about lack of info... but if you guide me through what I can do to get more specifics, I'll be happy to work at it.

Can you check if the kirigamigallery application also crashes?

cannot find kirigamigallery (or kirigami) app to download/install... ?

As I use this setup (fresh install of Kubuntu 16.10), plasma keeps crashing every so often (in addition to above reported unusable Discover).
Comment 6 Matt Z. 2016-11-23 00:06:32 UTC
a little more info (in addition to above)...

a fresh install
- nothing added
- compositor turned off

with 'nomodeset' xrand shows vga display at 1024x768 -- discover works fine
without nomodeset xrand shows LVDS1 at 1280x800 -- discover will not run

@ Matt Z.

You could add this ppa to get newest Nvidia graphis-driver:

https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa

Beforehand it might be interesting what you have installed:

dpkg-query -l *nvidia*

Seems like it's a problem with the graphics driver, not much we can do here.
