I just saw [here](https://bugs.launchpad.net/ubuntu/+source/lyx/+bug/129813) that this might be related to more general NVIDIA related X issues, that are [supposedly solved in the latest X 1.19](https://devtalk.nvidia.com/default/topic/976844/xorg-1-19-support/). I am on a fresh test install of Ubuntu 17.04 using the 340.102 driver now ([which supports X 1.19](https://www.phoronix.com/scan.php?page=news_item&px=NVIDIA- Legacy-6-Fermi-1.19))and confirm that lyx performance is good.

This program used to be my do- everything software, but it has become unusably slow. That is, keystrokes are even delayed in displaying when I type. The rest of the system is fine, and LyX didn't used to have such a problem. I'm not sure where to start in debugging this. apt-cache policy lyx lyx: Installed: 1.6.1-1~intrepid1 Candidate: 1.6.1-1 Version table: 1.6.1-1 0 500 http://ca.archive.ubuntu.com jaunty/universe Packages *** 1.6.1-1~intrepid1 0 100 /var/lib/dpkg/status lsb_release -rd Description: Ubuntu 8.10 Release: 8.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lyx/+bug/353449/+subscriptions -- Mailing list: https://launchpad.net/~ubuntustudio-bugs Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntustudio-bugs More help : https://help.launchpad.net/ListHelp
