On 4.7R xscreensaver 4.06 and 4.05 have the problem that the xscreensaver-demo
program fails thusly:
<~>$ xscreensaver-demo
X error in xscreensaver-demo: 11:04:58:
X Error of failed request: BadAccess (attempt to access private resource denied)
Major opcode of failed request: 147 (MIT-SHM)
Minor opcode of failed request: 1 (X_ShmAttach)
Serial number of failed request: 65
Current serial number in output stream: 66
I just upgraded from 4.5 to 4.7. I am using the *same* XFree86 installation I
was using *before* the upgrade, built from the port:
<~>$ pkg_info | grep -i xfree

Here is the verbose information from xscreensaver:
<~>$ xscreensaver -verbose
xscreensaver 4.06, copyright (c) 1991-2002 by Jamie Zawinski <jwz@jwz.org>.
xscreensaver: initial effective uid/gid was root/witr (0/1001).
xscreensaver: changed uid/gid to witr/witr (1001/1001).
xscreensaver: in process 425.
xscreensaver: 11:03:38: 0: xscreensaver-gl-helper: GL visual is 0x23 (default).
xscreensaver: 11:03:38: running on display ":0.0" (1 screen).
xscreensaver: 11:03:38: vendor is The XFree86 Project, Inc, 40200000.
xscreensaver: 11:03:38: useful extensions:
xscreensaver: 11:03:38: MIT Screen-Saver
xscreensaver: 11:03:38: Shared Memory
xscreensaver: 11:03:38: Double-Buffering
xscreensaver: 11:03:38: Power Management
xscreensaver: 11:03:38: GLX
xscreensaver: 11:03:38: XF86 Video-Mode
xscreensaver: 11:03:38: screen 0 non-colormapped depths: 24.
xscreensaver: 11:03:38: not using server's lame MIT-SCREEN-SAVER extension.
xscreensaver: 11:03:38: 0: visual 0x23 (TrueColor, depth: 24, cmap: default)
xscreensaver: 11:03:38: 0: saver window is 0x800001.
xscreensaver: 11:03:38: selecting events on extant windows... done.
xscreensaver: 11:03:38: awaiting idleness.
Since the combination of xscreensaver-4.05 and the above XFree86 worked
*before* the upgrade, but don't work *after* the upgrade, it seems reasonable
to be suspicious of 4.7 or the upgrade, doesn't it?
A quick google scan shows other people have had similar problems.
Any suggestions?
