From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux 2.2.17-14 i686; en-US; 0.8) Gecko/20010215 The installer does not use the scrollwheel. It wouyld be nice if it did when the user selects a mousetype with scrollwheel. Reproducible: Always Steps to Reproduce: 1. boot into installer 2. select Microsoft intellimouse (IMPS/2) Actual Results: scrollwheel is ignored in installer Expected Results: scrollwheel should scroll if the focus is on a scrollable window
Cannot detect presence of mouse wheel at this time.
I was not expecting detection of a mouse wheel, I was expecting usage of the mouse wheel when the selected mouse type is such that there is a wheel (Intellimouse, Logitech MouseMan Wheel, ...)
If we can't detect it, we don't know that it's there. If we don't know it's there, we can't set it up when the installer first starts the X server. Once the X server is started, there is currently no way in X to load a new mouse protocol without stopping and restarting the X server. This is really an X Windows problem. If you start X Windows with a generic (non-wheel) mouse specified in the configuration file, open a text editor and change the generic mouse to something like Intellimouse, the change does not take effect until X is restarted.
Does assuming the mouse has a wheel cause problems when it doesn't? AFAIK the wheel just acts like an extra set of buttons, which would just be ignored if no such button events ever occur.
Yes, it can cause problems with X. I don't really know why that happens, but I have seen X crash when I selected the wrong mouse in the installer. It seems to have something to do with the hardware, though, because I can use the same mouse on a different motherboard, and I don't have this problem.
