Bmarkus,
Tiny Core Linux 5.02a has the issue I'm speaking of. There was simply mention of xev, tests event codes for mouse and keyboard thats all, and that is in the Raspbian distro. Tried to compile xev from the sources for TCL but few to many issues to configure, presumably relying on dependencies in the Raspbian distro that don't exist in the TCL.
Seems 5.02a command line works fine but after copying files in the 4.x desktop distro to 5.x distro kills the scrolling in the resultant desktop. Command line for 5.x still works after logging out. 4.x distro when copied to 5.x distro refuses to see key events other than normal ascii characters. Only thing I've got left is "diff" the configuration files between the two distros in case I changed something inadvertently.
Cheers
Stefan
