- Let me preface ALL my comments with the fact that I'm running vmunix.709,
- with patches supplied by the porters of X11R5. (I believe their regsize
- patch is in error, but I use it anyway). I've rebuilt 709 by hand to
- add support for my tape drive, but otherwise it's stock (+ X11R5 patches)
- I have an ECS A2000/GVP Series II/8M 32bit.

- xterm -C successfully traps console messages for me, but xconsole fails
- for non-root users. Even if I _don't_ run `xterm -C' from non-priv'ed
- accounts, I don't get any panics. (of course, I only get the console
- messages in /var/log/messages...)

-
- I wish I had figured this one out (finals are _OVER_ after Monday, so
- I should be able to look at this a little more). My experience with
- `xdm' is identical to yours.

-
-
- I don't experience this display munging at all. (ECS A2000)

- ---------
-
- Have you gotten xload to work? According to docs, it needs to be
- in group kmem, and sgid in order to read /dev/kmem, and it is indeed.
- /dev/kmem is read for owner (root)/group (kmem)...
