Apps: Freezing & multiple windows when dragging mouse across screen - m654321 - 02-04-2018
From time to time, while using setup[1] (in signature below), I'll open an app such as LibreOffice Writer or say the Catfish file search tool and they freeze. At such times, when I drag the mouse across the screen, a trail of windows is left, a bit like the contrail of a jet aircraft - instead of a trail of exhaust, a trail of windows!
This morning the Firefox window froze (though I didn't get the contrail effect when moving the mouse), and the cross in the upper right hand corner was greyed out and wouldn't respond when I tried to close the window. So, I just opened a second Firefox window to allow me to continue working...
When the above has happened, I open HTOP to check what's going on, and usually find RAM and CPU activities are normal, i.e. they haven't gone up significantly, so I guess this excludes the possibility of an unwelcome malware visitor ..!?
Has anyone else experienced this, and why does it happen?

Hello m654321,
I have not experienced this and don't know the answer, but try by having a look around for you to help reducing the amount of time to search many results -
http://blog.csdn.net/zhangrelay/article/details/71909191
then through to https://code.google.com/archive/p/i7z/
and to release site -
https://01.org/powertop/downloads/powertop-v2.9
and finally to here - https://www.linuxexpres.cz/praxe/nastroje-top-atop-htop
english version - https://translate.google.co.uk/translate?hl=en&sl=cs&u=https://www.linuxexpres.cz/praxe/nastroje-top-atop-htop&prev=search
then checked in terminal it says -
"The program 'powertop' is currently not installed. You can install it by typing:"
Code:
sudo apt install powertopHere you will be able to see the C and P states , and know what causes the stops/froze windows/why does it happen, or gain more info towards this, to try and find solutions. If you put the results people can help with searching to reduce times for finding the info/any solutions to it.

Hi,
This is somewhat similar to what I was experiencing when I first started using LL. I was getting an error message in the syslog (Start / System / System Log - I suggest copying it to a text window, as it updates often), which suggested a kernel bug relating to the X window manager (X.org). Since about kernel 4.4.109 I had system freezes instead. These may have been unrelated, but it meant I didn't pursue the problem further, as curing the system freezes seems to have cured this issue also.
The system freezes were triggered by something Task Manager was doing, which I was running continually.
May I suggest keeping a record of every time this happens? Note down things like:-
- The exact data and time (to the second), so that you can check the system logs for any error messages,
- Note what app(s) you have running at the time, even if they appear unaffected,
- Note the app(s) which appear to be affected,
- Note what you were doing at the time.
Eventually, it may be that some pattern appears.
Hope that helps.

Many thanks Ian. What you said seems very useful. I had a look at the System Log file - there's a huge amount of information there though a bit unsure if I'll be able to make sense of it.
When the problem arises in future, I'll do as you mentioned and record the times when the problem starts & stops and copy/paste the output on System log. If I'm unable to interpret
the Sys log data I'll post it on this thread for others to comment on...
Many thanks again for your reply - much appreciated.
Mike
