To do this you have to create a directory "mkdir /etc/ld.so.conf.d/" then add this line to your /etc/ld.so.conf file...

Code:

include /etc/ld.so.conf.d/*.conf

reboot and everything now works.

Thank you!!

Worked. Finally.
When I added

Code:

include /etc/ld.so.conf.d/*.conf

at the end of the file GUI was still broken, but if I entered the line as first then I got GUI back.

p.s.
I knew that without VB Additions Slackware would work in VM. Did not think that may be considered as working system also because of resolution constrains without VB Additions.
I have old laptop with 32GB RAM and screen in VM at 1900x1020. I assumed that for VM this is more or less normal for laptop so running without guest additions was kind of waste (for me).

64-bit: Blank screen

bare system installed from -current with same packages selected:
Same as above.
But everything is fine after revert mesa to 18.0.x

some details:
When run xorg directly, it receive sigsegv and leave console blank
check with strace/gdb/valgrind, only got a callstrack list,
no idea how to dig more info...
Already rebuild mesa with debug info, but nothing changed/found.
Any suggestion is welcome

btw: Arch x86_64 is ok...
