Thanks. The second approach appealed to me, but trying it was a disaster. First, I took "*.conf" literally (with wild card). When I killed X server, it caused the display to loose all sync. I could only reboot at that point. I believe I should elaborate my prior problems with touchpad. When X started, the desktop is stable (I'm using .fluxbox without a desktop environment). But when I start an X application such as xterm or emacs, the slightest brush of my hand on the trackpad caused X applications to crash. When I closed X server (using CAD), it led to syncronization instability, which I could deal with with C-d or such. After introducing the xorg.d/*.conf stanza and killing X server, I couldn't get a stable command prompt to recover except another CAD to reboot. So I tried the first approach by installing xinput and while root is in X session issuing the command. This indeed killed the touchpad and left Trackpoint working. But when I shut down the X server (I'm not in habit of doing pkill X), I loose syncronization and am left with black screen without prompt. When I reboot and log in as user, I cannot run the command from a user prompt because user can't access X server, but when I do su for root to run it, I get Fatal server error: Server already active for display 0. Strange: I didn't get this error when logged in as root. This suggests a fluxbox hotkey won't work. I don't think I can put the xinit command in ~/.fluxbox/startup because those also are commands issued by user. Likewise for ~/.profile. So maybe I should put the command in /etc/X11/Xsession. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
