mouseconfig segfaults if /dev/mouse points to ttyS0 (1,2,...), X is not configured, and no mouse is present. If the soft link is returned to psaux manually, mouseconfig runs normally again. Reproducible: Always (the 3 times I tested it) Steps to reproduce: 1. Run mouseconfig, and choose a Generic Mouse on ttyS0 (with no mouse present, simulating user confusion over which serial port the mouse is plugged into). 2. Select No when asked to make the XF86Config changes. 3. mouseconfig exits. note the symlink /dev/mouse -> /dev/ttyS0, but /etc/sysconfig/mouse looks like this: MOUSETYPE="Microsoft" XMOUSETYPE="Microsoft" FULLNAME="Generic Mouse (serial)" XEMU3=yes DEVICE=/dev/mouse 4. Running mouseconfig again gives this error (across the top of the screen): mouseconfig: line 5 unexpected in /etc/sysconfig/mouse And the box shows: There was an error reading the file /etc/sysconfig/mouse. Would you like to proceed in creating a new configuration? 5. Hit OK. This presents you with a choice of serial mice. Choosing another mouse again results in the same behavior (probably because of the missing mouse). 6. The problem comes when you try to get back to using a PS/2 mouse. Since mouseconfig no longer gives you the option to choose a PS/2 mouse (or anything else) you delete /etc/sysconfig/mouse and... 7. Run mouseconfig again, which tries to probe for a mouse and then segfaults when it can't find one. Results: This seems to result from mouseconfig checking to see where /dev/mouse is pointing, and then presenting you with options that apply there (apparently all options apply to PS/2 mice). If /dev/mouse is pointed to a serial port without a mouse, mouseconfig cannot handle that situation and either segfaults or presents with the error and won't allow you to switch back to /dev/psaux. Expected behavior: The expected behavior would be for mouseconfig to allow you to choose your mouse, and set up /dev/mouse, /etc/sysconfig/mouse, and the XF86Config file accordingly.
small addendum: If /etc/sysconfig/mouse does not exist, mouseconfig continues to segfault until you touch or otherwise re-create the file.
another small addition: Now my mouseconfig doesn't work at all (/dev/mouse -> /dev/psaux, /etc/sysconfig/mouse exists but is empty). I tried cleaning out everything I could find -- the symlink, the /etc/sysconfig/mouse file, and the XF86Config-4. Still no go. I love test boxes...
This should've been fixed by the 7.1 mouseconfig errata. Closing - Errata.
