by doing the instructions of https://blogs.oracle.com/fatbloke/entry ... nux_guests
I am able to boot the X server but the Guest Additions of VirtualBox still fails at some point and some of the major features like mouse pointer detection and switching between different resolutions between host and guest are not available.
The error message in the Xorg.0.log is slightly different now.
"VirtualBox(0): Unable to determin whether the virtual machine supports mouse pointer integration ..."
See this screenshot from the log:
The other fixes like patching VirtualBox itself ... I don't know if that will really help me. Where do you get the source code for VirtualBox from?
Also as this is not a "play around" VM I just can't try various code patches and customized binaries.
Is this "patch" an official fix from the Virtual Box developers ?
Are there some instructions on howto install and compile VirtualBox from source?
Is there a version of Virtual Box somewhere that fixes those bugs?
By applying that patched VirtualBox, can I still upgrade it to later version once there is an official fix?
Sorry for the heaps of questions but patching source code is unfortunately a bigger issue on that VM then tweaking some configs.
