Description Roland Mainz 2004-10-31 21:23:48 UTC 
xdbedizzy does not work working on the Solaris/Xsun server (Solaris 8 with m64
framebuffer in 8+24bit mode in an Ultra5). It just hangs at 100% CPU load with a
black window, nothing gets rendered.

Trying the same with double buffering turned off (% xdbedizzy -nodb #) works
normal.

An attempt due figure out what's going wrong resulted in a scary truss log. It
seems that xdbedizzy is looping in libX11 until the hell freezes (I'll attach
the log in a few secs) ...

Make sure you've installed 108652-80 or later on Solaris 8, to get the fix in
Xsun for:
4985837  XdbeGetVisualInfo causes Xlib threads to hang

(Which is actually a server side bug, since Xsun is sending the wrong reply length
 for the DBEGetVisualInfo request and Xlib gets stuck waiting for more data from
 the Xserver which never arrives.)
Comment 6 Adam Jackson 2005-06-19 19:36:15 UTC 
bug in a demo app with a closed server != critical.
Comment 7 Alan Coopersmith 2005-09-12 20:55:36 UTC 
So did installing those patches fix the problem?

BTW, bug 4985837 in Xsun was the same as this fix which went into XFree86 in 2001,
so Xorg should already have the fix:

Marking broken (status null/blank) bugs in xorg with no activity in a long time as fixed. Please reopen if you think it's necessary, but first do a search if a similar bug report is already filed and in a NEW/ASSIGNED state. These bugs do not currently show in most search results as they do not have any status.
