newbie installation problem

[Bill Evans]

I'm a newbie trying to get Redhat 7.3 up and running. The computer is a 15 month old TasTech Duron 800 with a Genius Netscroll mouse. MS Windows  recognises it as PS/2 compatible and names the port as mouse port. The monitor is a Viewsonic E651 The graphics card a 32MB GeForce2 MX AGP   I cannot get the GUI running. Within the CLI the mouse does not function in Midnight Commander. Following startx, the error messages seem to indicate that the problem with the mouse is also the cause of the GUI failure. (I tried a couple of serial mouse drivers and these allowed the GUI to open but the mouse pointer was frozen.)   Copied from the XFree86log the error messages for all drivers are:   (EE) xf86OpenSerial: Cannot open device /dev/mouse Device or resource busy. (EE) Mouse0: cannot open input device (EE) PreInit failed for input device "Mouse0" ... Fatal server error: failed to initialize core devices   I have tried various settings within XF86Config-4 including those recommended on the Genius website. There it suggested Section:  "Pointer" Protocol: "IMPS/2" Device: "/dev/psaux" SampleRate: 60 BaudRate: 1200 ZAxisMapping: 4 5 Buttons: 3   My XF86Config-4 doesn't use this exact format, but I am sure I got it all set out properly.   I have an identical mouse running on another computer (Pentium 166) with Redhat 7.0 It works ok within mc. (There once again I have problems with the GUI but that's another story.)   The settings there are: Section "Input Device"     Identifier   "Mouse0"     Driver       "mouse"     Option      "Device"   "/dev/mouse"     Option      "Protocol"  "Microsoft"     Option      "Emulate3Buttons"   "on"     Option      "ZAxisMapping"    "4  5" EndSection   I have tried this setting on the Duron without success.   During installation at the point Xwindows is checked, everything seemed ok.  I think I actually clicked on that button where it asks you to click it if you see it (although I might just have hit Enter.)   I would be grateful for suggestions as to a trouble shooting sequence I should follow at this stage.   Bill
