Dear Stefan, hi list,

after returning from vacation, I upgraded a tumbleweed installation (zypper
dup), but X doesn't start anymore. It boiled down to:

[ 30.576] (EE)

Fatal server error:

Deviation from a standard installation:

libvnc is enabled with default parameters (in /etc/X11/xorg.conf.d/10-
libvnc.conf),
display manager is kdm of course, (since sddm doesn't support XDMCP).

System is using an AMD A6-6400K APU with Radeon(tm) HD Graphics

Reverting to Tumbleweed as of 2 weeks ago (last dup: 10180719 00:48) fixes
this problem and makes the system usable again. Disabling VNC makes X work as
well, but it is *primary* used via VNC.

Does anything changed with randr (protocol) lately, that tigervnc depends on?

Any other ideas? bugzilla?

While at it:
Identifier "Screen0" in /etc/X11/xorg.conf.d/10-libvnc.conf is missing a
closing ". SR?

I attempted to build a tigervnc 1.9.0, based on our 1.8.0, but failed so far.
Most patches apply with manual fixes only, some are upstream, but are missing
hunks, the cert and autoconf patches aren't applicable easily, and in the end,
it failed to compile :-(. Postponed it..

Cheers,
Pete
