Re: X.org 7.4 dying under Geomview

[Lloyd Wood <L dot Wood at surrey dot ac dot uk>]

Installed xorg-server-1.5.3-7 and the other 22 February updates and rebooted. Tested savi and geomview as described below.

Some improvement is seen in full desktop mode, where geomview doesn't crash, and can be used (modulo missing hardware acceleration.)

Crashing easily in multiwindow mode still happens - with the difference that the geomview camera window now never updates after being initialised before crashing.

(I would have expected the full desktop default to be an X desktop filling the single screen. Is there an easy way to disable virtual desktop/large screen behaviour in mwm and fvwm2? The startx fix is handy here; thanks.)
