GUI login on Solaris 10 guest fails to successfully start XSession as VBoxClient requires SUNW_1.2 symbol from libX11.so.4. A copy of ~/.dt/startlog is attached.
Partial workaround is to define LD_NOVERSION in ~/.dtprofile to cause runtime linker to not perform version verification.
This workaround however leaves clipboard functionality broken, as the "VBoxClient --clipboard" process dies when an attempt is made to copy text from the guest.
Running "VBoxClient --clipboard -d" shows:
bash-3.00$ /opt/VirtualBoxAdditions/VBoxClient --clipboard -d
ld.so.1: VBoxClient: fatal: relocation error: file /opt/VirtualBoxAdditions/VBoxClient: symbol Xutf8TextPropertyToTextList: referenced symbol not found
