[Pkg-tigervnc-devel] Bug#855350: Bug#855350: tigervnc-xorg-extension: Loading the tigervnc the extension makes the x server practically unusable

[John Tyner]

Yes and yes.

When X is sluggish, it is sluggish from the "get-go", as soon as I see my
log in prompt.

I've attached my working config and the log associated with it. I've also
attached the log associated with the sluggish behavior. In the latter case,
I added the file 99-vnc.conf to the /usr/share/X11/xorg.conf.d directory
with only the following lines:

Section "Module"
        Load "vnc"
EndSection
