Allow xserver_restricted_role domains to call/start Xorg (using startx), fixes 15-second lag/timeout (needs siginh permission as provided by xserver_domtrans). Apparently, the 15-second lag (or some other behavior) was already detected in the past, giving rise to the SIGINH permission in the xserver_domtrans() interface. However, domains that are given the xserver_(restricted_)role do not call the xserver_domtrans but rather the "standard" domtrans_pattern. The new patch suggests to use xserver_domtrans in the xserver_restricted_role, which automatically includes the siginh permission then. Signed-off-by: Sven Vermeulen <sven.vermeulen@siphos.be>
