Hello. I burned a CD with the 5.2 netinstall iso, and installed it onto a laptop (Acer Aspire 3680). Note that I'm *totally* new to laptops. The install went fine. But, when I boot it, it errors at the user login. A screen comes up, stating that X11 cannot start, and that it's probably the mouse. A bit of investigating revealed that there is no Synaptics module installed. It will boot into runlevel=3. I tried the 'upgrade' option of the netinstall disk; it saw that 5.2 is installed, and quit. |:( The X wiki suggested that I try adding this to /etc/X11/xorg.conf: Section "ServerFlags" Option "AllowMouseOpenFail" "1" EndSection Using "cat xorg.conf", I see Section "InputDevice" , which refers to the Synaptics module. Being new-ish to linux, I can't figure out the text-based editor (vi) to modify the file. I have "System Rescue CD" and "Ultimate Boot CD", but (apparently) they don't mount the installed system. I have some Fedora install disks (if they'd be of any help) - but not a rescue CD. It seems like CentOS doesn't have a rescue CD - would Fedora's help? I need to modify xorg.conf, or figure out how to install the Synaptics module. How can I do that?
