Mike, Thanks for the advice to try the HWE updates. Sorry I have been busy and the email that the bug was marked invalid has reminded me to chase this up.
I installed the HWE updates according to the instructions at https://wiki.ubuntu.com/Kernel/LTSEnablementStack That is, I ran sudo apt-get install --install-recommends linux-generic-lts-wily xserver-xorg-core-lts-wily xserver-xorg-lts-wily xserver-xorg-video-all-lts-wily xserver-xorg-input-all-lts-wily libwayland-egl1-mesa-lts-wily And then I re-tested octave-4.0.0-3ubuntu2~octave~trusty3 with the command plot([0 1],[0 1],'ko','MarkerFaceColor','y') ; and the plot appears perfectly without crashing. This confirms that the problem is in the graphics stack, not in octave. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1313952 Title: octave-cli: ../../../../../../../src/mesa/drivers/dri/i965/brw_eu_emit.c:267: validate_reg: Assertion `execsize >= width' failed.
