Retrieving useful infos on running Plasmashell

[Germano Massullo]

Today I have found out that plasma-desktop-5.5.1-1.fc23.x86_64 was using
1,9 GiB of RAM.
I would like to know if running
$ gdb
(gdb) attach "plasmashell's_pid"
can help to retrieve useful infos (for a bugreport) while the process is
running.
If you have any other suggestion, feel free to reply.
Thank you

Yes, that should be helpful. The process is well documented in Techbase [1] 
and Fedora wiki[2]. I have also been asked to submit valgrind log on 
occasions.

Folks in #kde-devel are quite helpful when filing kde bug reports.

Is there any way of saving the data that appears on screen
after a crash during booting?
No data appears to be written to /var/log/* (or journalctl).

Eg  CentOS-7-x86_64-LiveKDE-1511 crashes on my AMD/ATI Radeon server.
I know how I can solve this problem, ie install CentOS-7.2,
but I don't know how I could save the screen-data.

I am looking at [1] to attach GDB to an already running Plasma process.
But everytime I run a command like
$ gdb plasmashell 1865
Plasma shell freezes until I exit from gdb. A freezed Plasma, prevents
me from reproducing the crash. Any suggestion?
