The Subject says it; you can delete the 284965 ticket. However, I wish to relate my experiences with this problem, as it may help the Debian team help others avoid similar problems in the future.
[ It is probably useful to mention that I have been running Linux exclusively at home and at work since 1993, and I have had my problems with the X11 systems of that time: I have had to adjust the huge mode lines of those days and edit e.g. the clock speeds till fuzzy lines of ill-sychronized horizontal refreshes gradually settled down into a semblance of order(this on all manner of monitors, including at first ancient Hercules displays) ] Here is the sequence of difficulties I experienced, all, as events showed, with the /etc/X11/XF86Config-4 file: 1. The Woody installer didn't put any "Modes" in any of the Display SubSections of the Screen section. Fortunately I had saved my Red Hat XF86Config file, and since my errors had to do with no screens found, I decided it wouldn't hurt to put Modes in. But that didn't help. 2. As I reported in my immediately previous message, I was able to find out, through googling with lynx, that the option "UseFBDev" was causing, for whatever reason, the X11 to fail completely. After that Option, in the Video Card section, was commented out, I got at least some part of the X display.(Tnank goodness I left the Mode lines in!). 3. The mouse was, however, still flakey. At the suggestion of a friend, who has been doing Debian for several years, I got rid of the Generic Mouse stanza, with its /dev/input/mice and its ImPS/2 Protocol. Only after this grappling and groping, which involved many many reruns of dpkg-reconfigure, plus several tries with the various tools for making XF86Config files that exist, was I -- with afore-mentioned help -- able finally to achieve a rock-solid X11 display. I don't have to recapitulate what needs to be fixed -- the inadequacies are apparent from the numbers 1, 2, and 3 above. I hope that attention will be paid and efforts will be made to make a standard tool for making -- at least on a vanilla system, which mine is -- a workable XF86Config file.
