Description Davide Bolcioni 2001-12-30 15:46:04 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv: Gecko/20010901

Description of problem:
Picking "penetrate" for a demo in xscreensaver-demo freezes X solid on the
picture showing the "score" (text is badly garbled). The same
freezes occur when random selection of screen savers stumbles over the
penetrate module.

Version-Release number of selected component (if applicable): 3.33-4

How reproducible:

Steps to Reproduce:
1. startx -- -dpi 100x100
2. run xscreensaver-demo from a terminal window
3. pick "Penetrate"
4. click "Demo"

Actual Results:  The demo runs until castles are destroyed, displays the
closing screen with garbled "high score" and freezes X solid. No VC
switching, no
Ctrl-Alt-Backspace. Could not try telnet, not on a LAN. Did not try SysRq,
not enabled.

Expected Results:  Should close and return to the desktop.

Additional info:

Note that startx is launched at 100x100 dpi; I have not tested if this
makes a difference. The host is a Athlon 700 with a Matrox G400 32MB.

If the X server hangs, that indicates an X server bug.
Comment 2 Davide Bolcioni 2002-01-25 15:54:17 EST
Hmmm ... does the above imply that I should close this bug and open a new one ?

In any case, I can provide some extra information:
- booting with "mem=nopentium" (my system is Athlon + AGP) makes no difference;
- at 75x75 dpi "penetrate" runs flawlessly;
- at 100x100 dpi "penetrate" does not *always* hang ... only when I have some
  "castle" left (at 75 dpi, this writes "Level 1 Cleared" ... at 100 dpi, the
  letters are garbage) - if all castles are destroyed, I see "Game Over" at
  both resolutions.

The upgrade to RedHat 7.3 apparently fixed this (XFree86-4.2.0-8,
xscreensaver-3.33-4). Works fine at 100 dpi now.

Thanks very much for the update.  Closing bug as fixed in CURRENTRELEASE
of Red Hat Linux 7.3.

Take care.
