cant left clic on nodes and in Viewer

[willDTF]

everything work well except that i can't select a node with left clic and move the node or link it to an other node.
it draw immediatly a selection box in the node editor (the only way to select a node actually for me) and nothing happened in the viewer
middle and right click work as espected
no error in the terminal

i use gaffer 0.48.0.0 and 0.49.0.0, binary from gaffer release page, on fedora 28

hi, it's on a laptop so it's a 6gig gtx 1060 coupled with intel one
drivers are provided by negativo17, it's nvidia graphic driver 3.396.54-2

It's probably not the same problem I get on Intel, where I can only box select nodes. Also on Intel I can't connect nodes by dragging a nodule from one node to another.

I have to switch to my nvidia card to use gaffer.

How do you switch between nv and Intel? It it dynamic like windows or do you have to restart?

that's look similar,
i use bumblebee to normally switch gpu without rebooting but i have no garanty that i really run gaffer on nvidia gpu, i will try to look closer on it then let you know
thanks

ok so i can tell that gaffer wasn't launch on nvidia GPU so i'm in the same boat as you with intel GPU problems. i try to find a way to launch it on nvidia then let you know

This Intel problem has been bugging me for a while. I thought it was a driver problem but upraded recently and the problem persists. Given it's not just me who has this problem, I'll take a go at fixing it.

That would be great …
I struggled with this from the beginning.

Not being able to resolve, I gave up gaffer.

I had the issue on Ubuntu 18.04.

Solve
Logging within Gnome or Unity instead of Wayland solved the issue for me.

Elantech
Having Elantech Touchpad as device input fixes the left click behavior.
Whereas it's not listed with wayland protocol activated.

Within Gnome:

alex@laptop:~$ xinput list
⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ ETPS/2 Elantech Touchpad                	id=12	[slave  pointer  (2)]

I have just experienced this same issue with the latest gaffer 0.58.1.0
also on a laptop.... (had no issues on my workstation).

not sure i understand what the fix is....

Closing as an Intel graphics fix has been released in Gaffer 1.4.0.0b6. Please reopen if the issues persist.
