Quoting a .sig from an email can result in the part of your messages that
follows the quote to disappear from an attempt to respond. That's what
happened here. Never quote a .sig. It's never relevant to a response.
Anyway the fact that you have this problem using older hardware only in KDE
but not LXDE suggests that your old hardware was not among the hardware
tested as drivers and KDE have continued to evolve. Likely your hardware
requires compositing disabled, but KDE defaults to enabling it. Had the
drivers for your hardware been tested during 11.4 development, probably
compositing would have been disabled by openSUSE's Xorg devs or Xorg's devs
at the driver level.
It's possible saving
Option "Composite" "Disable"
as /etc/X11/xorg.conf.d/70-composite.conf would be all you need. It may be
that you would need to paste it into your xorg.conf file(s) instead. This
constitutes global disabling of compositing, which means it'll be disable
regardless which DTE you run. There will be a KDE specific way to disable it
on a user by user basis without requiring KDE to function first to turn it
off via systemsettings, but I have no idea where that is.
More specific help really isn't possible without knowing which hardware you
have, particularly the Intel and NVidia. Vanta is really old, and probably
got little or no testing. It probably is incompatible with the nouveau driver
reported to be in use by the Xorg.0.log snippet you included. Try following
the instructions to disable nouveau in one of the included URLs for that
machine. For the other machines, go through all of them and try again.
Also, any of *113* or *114* in http://fm.no-ip.com/Tmp/Linux/Xorg/ or
http://fm.no-ip.com/Tmp/SUSE/ may include a matching xorg.conf in its head
that may serve as a template to manually altering older xorg.conf files to
work in 11.4. Most of what older releases' xorg.conf files included should
not be needed in releases newer than 11.2 (the last version that included
SaX2 for creating them). Note that xorg.conf should not be needed, but for
older hardware it's common for at least parts of their content to be needed
to work around untest incompatibilities in old hardware. It's often simpler
to narrow down what's needed by using the (smaller) individual files in
xorg.conf.d/ instead of xorg.conf.
FWIW, I have 11.4/KDE working on a lot of old hardware, but IIRC Vanta is not
in any of them I ever use.
If you can't get this figured out on your own, or find out how to disable
compositing only in KDE via text editor from someone here, you may be better
off looking for a solution in http://lists.opensuse.org/opensuse-xorg or
http://lists.opensuse.org/opensuse or subscribing to those lists and asking
"The wise are known for their understanding, and pleasant
words are persuasive." Proverbs 16:21 (New Living Translation)
