[Bug 1716098] [NEW] Slight delay with wacom CTL-480 and nouveau drivers on external monitor

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Consider the following setup:

- Thinkpad W530 with optimus (discrete gaphics nvidia Quadro K2200M)
- On docking station
- Connected to an external screen (Dell U3014, 30 inch) via DisplayPort
- Using nouveau drivers
- Using wacom CTL-480 in xournal

When writing text with this setup I notice a minimal delay or/and
minimal imprecision of the pen which makes writing annoying. Since the
effect is very small, it is hard to describe, but if you write, you feel
the problem.

If I switch to the laptop screen, everything works smooth. It also works
smooth on the external screen if I use nvidia-340 driver instead of
noveau.

Maybe there are some options I could try to make it feel smoother with
nouveau drivers, maybe this is a bug.
