Black screen with VBoxLinuxAdditions
To make some tests I have installed a Slackware 14.0 32 bits in Guest in Virtualbox 4.2.12, from a Fedora 18 64 bits.
When I install VBoxLinuxAdditions, modules are OK, everything is "done", the scroll mouse works (doesn't work before), but at the reboot I get a black screen, I have to remove Additions to boot Slackware.
I did not find suspect logs in "messages", nor in "Xorg.0.log".
Some ideas ? Thank you.
