It is impossible to change the theme of libre office. Tools-->Options --> Personalization--> Own Theme. It seems that several themes does not work, and when I found one that works, I could not change it to another. In Windows it works perfectly using the same computer: Acer Aspire 5738ZG Intel Pentium T4300 64-bits. Xubuntu. xfce and KDE Desktop.
Sorry for my poor English!!
Which LibO version are you using?
It works for me on Ubuntu & Unity. Selected the first abstract theme and after applying and checking, changed to the 2nd abstract.
Set to NEEDINFO.
Change back to UNCONFIRMED after you have provided the version information.
Ubuntu 14.10 64-bit

Can you please try with 4.4.2? Here's how you can have multiple versions at the same time: https://wiki.documentfoundation.org/Installing_in_parallel/Linux
Thank you, with the lates version it works, I did not realise there were a newer version of LibreOffice. Now I am going to change the status to Resolved
Thanks for testing! I'll change the status to WORKSFORME, as we don't know the exact details of what caused the problem.
