The installer prompts the user for mouse type. In my case this is a PS2 mouse and it is autodetected. The installer uses this information to configure - X windows - gpm However there is a third place that needs configuring that the installer forgets, - SVGAlib (/etc/vga/libvga.config) Without this fix a user has to know how to manually fix svgalib by editing the textual config file. Messy. And the user is deprived of quake :-)
Thank you for the suggestion. It has been noted and we will consider this for upcoming releases.
