I added environment variable as you said:
# echo "allow_rgb10_configs=false" > /etc/profile.d/gnome-workaround.sh
But it not helps workaround problem.
Maybe we made a mistake in the diagnosis?

Re: LLVM 7.0 + Wayland = broken mouse control

[mikhail]

Can you install Fedora 27  + llvm and mesa from this repo
"https://copr.fedorainfracloud.org/coprs/che/mesa/" + use kernel from here "git clone -b amd-staging-drm-next
git://people.freedesktop.org/~agd5f/linux" and check why not worked
mouse hover + click and crashes Unity games?

At least identify the cause of the two problems.

No, it just means there's an error in the way you're trying to set the
workaround. Maybe it needs to be "export allow_rgb10_configs=false"?

You can also try the method I described in
https://bugs.freedesktop.org/show_bug.cgi?id=104808#c2 , I verified that
to work.

You right, my mistake I forgot add export.
Of cource right variant:
echo "export allow_rgb10_configs=false" > /etc/profile.d/gnome-
workaround.sh

Mouse click now works again with latest llvm and mesa.
It is unfortunate I don't know how apply this variable to the login
screen (gdm).

Anyway, thanks.

I think you can set it by:

echo "allow_rgb10_configs=false" >> /etc/environment

Big thanks, now it works also on the login screen.
And /etc/profile.d/gnome-workaround.sh not needed.
