added the new defaults.conf and log out
get black screen with error box but can now read the text
can't open file /usr/share/gdm/themes/VL-seven/VL-seven.xml
Clicking the ok takes me to the flower login screen and it has text now.
Reboot from there brings same error box and clicking the ok takes me to flower login with text, same as logout
Created a folder named VL-Seven in /usr/share/dgm/themes and copy/pasted the content of StarFlash.
Then renamed the .xml VL-Seven. this gave error for /VL-Seven/StarFlash.xml so renamed back to StarFlash.xml
now can logout and StarFlash screen has text.
The remaining issue can likely be attributed to something else, the video card?.
Random lines of text may appear to be missing but gliding the pointer over the area or clicking brings it to view. I have this issue with word processing aswell and in previous B.iso's so attributed the login issue as a more severe version of that. however it remains after this fix.
Ie if I logout and click session, everything looks fine except fluxbox text is missing, click cancel and then session again and all is normal, or rather than click cancel just slide pointer over the area and it appears.
in this case though the box is gray and I can see the text but it is whiteish so in the word processor can not see as it is white on white.
anyway thanks for the fix, I now have text on the login screen.
