Have just finished rebuilding my Octane 2 with a fresh instance of 6.5.0 with the 6.5.29 overlay set on a brand new 15krpm disk - it's all nice and lovely now.

I've also added a few bits and pieces from a just nekosync-ed nekoware repository... this included xscreensaver and rss-glx for thepretty .

Trying to start xscreensaver-command -prefs throws up a whole load of cairo / pango / gdkpixbuf errors in the console and the preference window shows square characters instead of text - clicking on the left preference pane (the one which would list the actual screensavers) causes the application to crash.

Any ideas? I don't have a dump of the error at the moment but will attempt to do so this evening.

Ok, image of the font/image problem here:

The actual output in the terminal is:

Code: Select all


   [Sulfur]:~ $ xscreensaver-command -prefs
   

   Error reading Pango modules file
   

   

   (xscreensaver-demo:2813): Pango-WARNING **: No builtin or dynamically
   

   loaded modules were found. Pango will not work correctly.
   

   This probably means there was an error in the creation of:
   

   '/usr/nekoware/etc/pango/pango.modules'
   

   You should create this file by running pango-querymodules.

   .....
   

   .....
   

   .....

the file /usr/nekoware/etc/pango/pango.modules was indeed blank after the install in swmgr (and I had errors about missing gdkpixbuf modules), but I added a modules line to the file to point to where the pango .so modules are located... now no more gdkpixbuf errors and the xpm images show.

The final issue is that when you click on the left hand pane (which would normally show the list of available screensavers, the program terminates and spits out the following debug info in the terminal:

Code: Select all


   (xscreensaver-demo:2813): Pango-CRITICAL **: file pangocairo-fontmap.c: line 196: assertion `PANGO_IS_CAIRO_FONT_MAP (fontmap)' failed

   Green mask: 0x000ffc00
   

   Blue  mask: 0x3ff00000
   

   Please file an enhacement request (quoting the above) at:

Is this a known issue on VPro hardware? If not, then what have I broken and how do I fix it!

I'd suspect that neko_fontconfig is broken. Downgrade fontconfig and/or verify that fc-cache works.

Tried later versions of cairo, fontconfig, freetype and gtk as in nekoware beta, no luck; got segfaults on launching xscreensaver and fc-cache.

Removed those versions and reinstalled the versions from nekoware current and I now have fonts showing in xscreensaver and the preference pane no longer crashes the program.

Bizarre, but it's working now!

I don't have xscreensaver but fc -cache does this

Code: Select all


   fewel 1% fc-cache
   

   Segmentation fault

Haven't noticed any other problems with the /beta versions of cairo, fontconfig, etc tho ...

Removed those versions and reinstalled the versions from nekoware current and I now have fonts showing in xscreensaver and the preference pane no longer crashes the program.

I just noticed that I have both fontconfig 2.3.2 and 2.8.0 installed. Umm, isn't the newer supposed to supercede the older ? Except in rare weirdass cases ?
