Sigh, with kernel 4.1.0.1.1~rc2 I just had the cursor disappear, so it is not fixed as I had hoped. :\
That said, arround the time this happened I noticed this in syslog: Jul 16 10:37:33 jamie-XPS-13-9343 kernel: [11297.284147] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1467595 Title: cursor sometimes disappears on XPS 13 9343 and external monitor To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1467595/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
