19 | # What this script does: X.org 1.5 introduces full hardware autodetection
|
---|
20 | # and no longer requires the user to provide an X.org configuration file.
|
---|
21 | # However, if such a file is provided, it will override autodetection of
|
---|
22 | # the graphics card (not of vboxmouse as far as I can see). Although this
|
---|
23 | # would normally be the user's business, at least Fedora 9 still generates
|
---|
24 | # a configuration file by default, so we have to rewrite it if we want
|
---|
25 | # the additions to work on a default guest installation. So we simply go
|
---|
26 | # through any configuration files we may find on the system and replace
|
---|
27 | # references to VESA or framebuffer drivers (which might be autodetected
|
---|
28 | # for use on a VirtualBox guest) and replace them with vboxvideo.
