Yesterday I had a rather uncommon situation I can't wrap my head
around. I run Slackware 13.37 x64, start my system inside tty. I
logged in and run startx as usual. Flubxox, my WM of choice started
correctly. Then, I tried to use ristretto to open on image stored on
SAMBA share that is added to /etc/fstab and has been mounted
automatically during bootup. My LAN connection is handled by USB-RJ45
adapter which is pretty unstable sometimes. During opening an image,
ristretto froze. I already knew that this means network problems with
accessing remote share so I re-run inet script which reconfigures
networking on Slackware. Then, I found ristretto process with `ps aux'
and killed it. It didn't stop immediately and was still present in `ps
aux' output but it was enclosed within square brackets. I don't
remember if I tried to kill it again with -9 or it closed by
itself. However, after this incident, I wasn't able to start any X
programs. When I tried to start ristretto, xeyes, wmctrl I got this:
can't open display
Error: Can't open display: :0.0
At the same time I had Emacs, firefox and uxterm running inside
fluxbox. It seems like some program wiped all entries in xhost and
forbid me from accessing local X server. I realize that situation is
pretty strange. There are no related information in Xorg log or in
dmesg. Have you ever encountered a similar situation? My version of
both Slackware and Xorg are pretty old, maybe there are similar bugs
reported?
