Alexander,
My system uses a Raedon 9000 card in dual-head mode, FreeBSD 5.2.1-RELEASE-p3
and a recent ports tree. Xscreensaver-demo was working fine then
xscreensaver-gnome version was updated and the breakage occurred. I did
not change my basic config, just portupgraded to the latest.
Here is the exact error message I was getting:
------------------------------------------------------------
hilton>$ xscreensaver-demo
xscreensaver-demo: 12:32:45: error closing "/usr/home/stephenh/.xscreensav
er": Bad file descriptor
xscreensaver-demo: too early for dialog?
Fatal error 'Unable to read from thread kernel pipe' at line 1100 in file
/usr/src/lib/libc_r/uthread/uthread_kern.c (errno = 0)
Abort trap (core dumped)
hilton>$
------------------------------------------------------------
Deleteing /usr/home/stephenh/.xscreensaver had no effect.
Around a week ago I totally rebuilt this system from scratch, all s.w.
installed via ports, and still the xscreensaver-demo crash. The
${PTHREAD_LIBS} hack did fix the problem. All other applications seemed
to be working well, the screensaver appeared as the only borked item.
I do use a /etc/libmap.conf like this:
----------------------------------------------------------
libpthread.so.1 libc_r.so.5

Should I have this in my /etc/make.conf:
COMPAT4X= yes
Or is this unneeded or a source of problems ?
Any insight or ideas as to what may be "misconfigured" etc... ?
The only app that misbehaves is xscreensaver-demo, and the fix of adding
${PTHREAD_LIBS} to the LDCONFIG line in the Makefile does solve the
xscreensaver-demo crash.
Is there some aspect to the Raedon drivers that is tickled by dual-head
mode?
