Thanks for the info; I already tried that way on my search for X; as mentioned it may be my BIOS Release (8.4) which I need to get my SSD recognized/bootet. The Toshiba Tech told me 2005 it was never released and will be; with this upgrade I was limited to 1,5MB VGA RAM (1024*768*15Bit Virt Desktop), so there might be the link to my problems. Under FBSD the patched X client works, so I guess I get it working with gcc at my side.
Sound is more important: I'll try the next days to use your mods.
next issue will be started soon for my low RAM, as the RAMloopbacks leaves nothing after ALSA was installed. So I guess the local=switch will be needed
P.S.: the nvram is a small NiCd Akku and will recharge somehow; a better replacement is a small Goldcap 5V, which lasts for about 1 week offline and don't leak out as deep discharged NiCd do.
