Dear Christopher, thank you very much for you reply! I beg pardon for responding so late - I could not try your suggestion until now. I updated the BIOS: now - from what I could see - LibreOffice seems not freezing the system anymore, but 'simply' crash Compiz.
Giving in a terminal the command sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date I obtained the following output: 220 06/23/2010 Trying to play around with LibreOffice options, I could however observe that my problem seems related to the use of the sidebar: after deactivating the latter, crashes and freezes seems to be disappeared... Well, until now. >From what I could see, I'm induced to think the bug is actually related to >Compiz - likely, to its management ot the Nvidia graphic card. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1261237 Title: 10de:0653 [Asus K70IO] System crashes (freezes) while LibreOffice is running To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1261237/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
