    LibreOffice Greying out as Ubuntu used one core 100% and the other 7 remain idle

    I am not sure if this is hardware or Ubuntu problem or LibreOffice problem.

    There are 8 cores in my machine. I am on Ubuntu 15.10 and LibreOffice 5.0.2.2. LO frequently greys out on me and when I check the system monitor, I find that one of the cores is 100% occupied and the rest are practically idle. When I look under processes, LO can be using 400+ Mib...which should not be a problem as I have 2.5G of memory. Nonetheless, LO stays frozen in grey for ages. I am on the default memory allocation as given by LO in Tools/Options/Memory and changing that allocation seems to make little difference as far as I can see.....though I have not tried on Ubuntu 15.10...as it made little difference on previous Ubuntus. I have tried overclocking but that does not help either.

    Any suggestions would be greatly appreciated.

    Have you tried another office suite?

    Trying another office suite does not solve the issue with LibreOffice. That's avoidance, not a solution. Let's help the OP with LibreOffice, not go on a tangent.

    Thanks.

    It is a peculiarity of Libreoffice 5. I am getting it on xenial xerus (16.04 development branch) on a machine with a 2 core CPU, 1GB RAM and an Nvidia GT220 with 1GB video memory. It is far away from being a high spec machine. But I never saw this effect with Liberoffice 4.

    I have system load indicator installed and I can see in the app indicator what is happening to my system resources and this happens with very little CPU activity or disk activity and with only 500MB or there abouts of RAM being used. It happens with large documents of about 100 pages or more.

    The Find function is a lot slower than it was with Libreoffice 4.

    Regards.

    It is a machine. It is more stupid than we are. It will not stop us from doing stupid things.

    I've been running L.O. 5 since it was released on several installs, installed via PPA and part of 16.04. I've not seen that behavior, I wonder what triggers it.

    Can you correlate the greying out with anything? Size of file? Calc, Writer, Impress, etc? Whether it's reproducible by a particular action?

    I don't know what "overclocking" does, but doesn't that set your experience apart from the "average" user?

    @kurt18947,

    Whats's the oldest hardware you feel that can run LO5 decently?
