Bug#505379: phosphor segfaults
FWIW, started using phosphor again recently and I'm seeing the same problem. I'm running phosphor from KDE 3.5 with fortune as source for text (had to edit /usr/share/xscreensaver/config/phosphor.xml to be able to use that).

You are using the proprietary nvidia driver, and I guess the screensaver triggers a bug in the driver. Maybe you can file a bug upstream, see http://us.download.nvidia.com/XFree86/Linux-x86/1.0-9755/README/chapter-06.html If you can provide a backtrace that shows xscreensaver is doing something wrong we will of course take a closer look. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Hi, on Tue, Nov 25, 2008 at 01:19:45 +0100, I wrote: Do you run it fullscreen? You can use the -root option in a bare X session (failsafe xterm session), i.e. without desktop backgrounds etc hiding the root window. With gdb I did use the same options as configured in xscreensaver, ie. /usr/lib/xscreensaver/phosphor -root -delay 34000 -scale 3, but within my normal session. I have it running with that commandline in a separate X server via startx for a couple of days now. it still runs fine, whereas I had two or three crashes of the phosphor run by xscreensaver in my usual X session during that time. I'll let it running some longer, but it seems this won't reproduce the crash either. :/ elmar -- .'`./\ | :' : Elmar Hoffmann [EMAIL PROTECTED]ASCII Ribbon Campaign \ / `. `'GPG key available via pgp.netagainst HTML email X `- vCards / \ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Thanks for your bug report. Please attach your /var/log/Xorg.0.log and /etc/X11/xorg.conf. gdb slows down execution a bit, so it sometimes helps against timing issues and races. Can you make phosphor crash standalone without gdb? Do you run it fullscreen? You can use the -root option in a bare X session (failsafe xterm session), i.e. without desktop backgrounds etc hiding the root window. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Done. gdb slows down execution a bit, so it sometimes helps against timing issues and races. [...] Yeah, that would be an explanation. My thinking was along the lines of the environment xscreensaver runs the hacks in being different in some way to running them on their own... [...] Can you make phosphor crash standalone without gdb? I think I ran phosphor without options (ie. in a window) for a bit without it crashing, before I tried gdb. Do you run it fullscreen? You can use the -root option in a bare X session (failsafe xterm session), i.e. without desktop backgrounds etc hiding the root window. With gdb I did use the same options as configured in xscreensaver, ie. /usr/lib/xscreensaver/phosphor -root -delay 34000 -scale 3, but within my normal session. I just now started phosphor with these options inside xnest (though I guess the different nature of xnest compared to the real server will not make it crash...). I'll look into having an additional, real X session running to try it there. Replacing my normal session with a failsafe one is unfortunately not an option on my main workstation. ;) elmar -- .'`./\ | :' : Elmar Hoffmann [EMAIL PROTECTED]ASCII Ribbon Campaign \ / `. `'GPG key available via pgp.netagainst HTML email X `- vCards / \ # /etc/X11/xorg.conf (xorg X Window System server configuration file) # # This file was generated by dexconf, the Debian X Configuration tool, using # values from the debconf database. # # Edit this file with caution, and see the /etc/X11/xorg.conf manual page. # (Type man /etc/X11/xorg.conf at the shell prompt.) # # This file is automatically updated on xserver-xorg package upgrades *only* # if it has not been modified since the last upgrade of the xserver-xorg # package. # # If you have edited this file but would like it to be automatically updated # again, run the following command: # sudo dpkg-reconfigure -phigh xserver-xorg Section Files FontPath/usr/share/fonts/X11/misc FontPath/usr/share/fonts/X11/cyrillic FontPath/usr/share/fonts/X11/100dpi/:unscaled FontPath/usr/share/fonts/X11/75dpi/:unscaled FontPath/usr/share/fonts/X11/Type1 FontPath/usr/share/fonts/X11/100dpi FontPath/usr/share/fonts/X11/75dpi # path to defoma fonts FontPath/var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType EndSection Section Module Loadbitmap Loaddbe Loadddc # Loaddri # nvidia Loadextmod Loadfreetype Loadglx Loadint10 Loadrecord Loadtype1 Loadvbe Loadv4l EndSection Section Extensions # Option Composite enable EndSection Section InputDevice Identifier US Qwerty Keyboard Driver kbd Option CoreKeyboard Option XkbRules xorg Option XkbModel pc104 Option XkbLayout us # Option XkbOptionsctrl:nocaps EndSection Section InputDevice Identifier US Dvorak Keyboard Driver kbd Option CoreKeyboard Option XkbRules xorg Option XkbModel pc104 Option XkbLayout dvorak Option XkbOptionsctrl:nocaps EndSection Section InputDevice Identifier USB Mouse Driver mouse Option CorePointer Option Device/dev/input/mice Option Protocol ImPS/2 Option Emulate3Buttons false Option ZAxisMapping 4 5 EndSection Section Device Identifier NVidia Graphics Card Driver nvidia Option NoLogotrue Option RenderAccel true Option BackingStore true Option AllowGLXWithComposite true EndSection Section Monitor Identifier DDC Monitor Option DPMS EndSection Section Monitor Identifier TV HorizSync 30-50 VertRefresh 50-60 EndSection Section Screen Identifier Default Screen Device NVidia Graphics Card Monitor DDC Monitor DefaultDepth24 # Option ConnectedMonitor CRT SubSection Display Depth 8 Modes 1600x1200 1400x1050 1280x960 1152x864 1024x768 800x600 640x480
