I tried to get Kmid to work ( Timidity command line software works ). I get the message "unable to open /dev/sequencer" . On checking there is NO /dev/sequencer. Somewhere ( cannot get back to it ) I also found "midi not enabled in config" or equivalent . I dont even know where to start looking.

try to load alsa sequencer module (preferaby at boot)
modprobe snd-seq-oss
modprobe snd-seq-midi

Kmid can't play midi files unless it has a midi sequencer
to play them through. This could be a hardware sequencer
on a soundcard or a software sequencer playing through a
soundchip that doesn't have its own built in hardware
sequencer. Sounds like you need to install a software
sequencer.

While trying to get this to work the system crashed . I could not boot in.
However I tried unsuccessfully to install Fedora core 4 . The graphic install just does not come up . However I went ahead with the text install . No luck . It gets stuck on something called the Welcome . after saying Xserver started successfully . Now any suggestions for this would be welcome. Is there a way to setup display from the console?

If you are using Xorg for X, then there will be a file at /etc/X11/xorg.conf which you can edit with your favorite text editor.

nano -w /etc/X11/xorg.conf

If you are using Xfree, there should be a similarly named file in the same location. You can also look at the log file for X to see if it gives you any good ideas.

cat /var/log/Xorg.0.log
--or--
less /var/log/Xorg.0.log
--or--
cat /var/log/Xorg.0.log | grep EE
--or--
cat /var/log/Xorg.0.log | grep WW

less will let you browse through the entire log. it will probably be quite long. using grep EE will just display the lines with errors. Using grep WW will just display the lines with warnings. Note that if you are using Xfree, the file will have a different name.

Thank you I will try this since I do want to upgrade to Fedora 4 . I have got FC3 running fine , but it is a locally manipulated (PCQuest.com India) version and many things fail without reason. Like complete help does not come up ...

Thank you for this . Hope to try it out . I still have a partition ( crashed one ) where I could put a new FC4 version .
