requested an impossible situation or if you are using the unstable

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against

Если верить sisyphus.ru, xorg-drv-synaptics собирается из иксов, а
xorg-x11-drv-synaptics - из пакета synaptics (и у него меньше версия и в
сизифе его нет). Багу на qsynaptics, чтоб не просил, видимо. А то и на
xorg-x11-drv-synaptics, чтоб убрали.
