It's probably prudent to fix that /dev/null issue system-wide, rather than just
via one of your login environments. You _could_ put the chmod command into a
system startup file under /etc/rc* : but in your case it's probably less hacky
if you try to correct it via udev.
I don't use udev (& instead just use static device files), so the following may
be better addressed by someone on-list who does use it.
For the command:
grep -r null /etc/udev /lib/udev/[a-ce-z]*
, do you get any lines like:
/lib/udev/rules.d/50-udev-default.rules:KERNEL=="null|zero|full|random|urandom",
MODE="0666"
or:
/etc/udev/rules.d/40-fix-permissions-rules:SUBSYSTEM=="mem",
KERNEL=="null|zero|full|random|urandom", MODE="0666"
? If not, then you might want to create something like
'/etc/udev/rules.d/40-fix-permissions-rules' ( 0644 root root ) with the
contents
as shown in the above example grep output.
You also might want to double-check the permissions &c on
/dev/{zero,full,random,urandom} too (ref. the lists in the above example grep
output).
As for the X11 stuff: not sure what's caused that - would need to know more
about what you've been installing/configuring/&c. It can be useful to profile
the sytem before and after making changes (e.g. installing software), to help
see what's actually being change don the system. Even a crude 'ls -latrRF /' or
'find / -ls' pre-/post-, saved to logfiles and diffed, can be useful; and you
can refine it from there.

Will break that printing stuff out into a separate thread.
