I think I have a work around. Boot up 2.4.3 with the framebuffer enabled as normal. Log in as root and use the fbset program to change the settings for all the framebuffers. eg.
fbset -a 1024x768-70
or whatever works for you. fbset has its own man page.
This makes everything hunky-dory for me, in that after running fbset I can go in and out of X without ever losing the video signal.
Petr, I had a look at the drivers/video/matrox subdir and there's no difference between 2.4.2 and 2.4.3, however there are differences in the drivers/video dir to do with framebuffers. The files that have been changed in drivers/video/ are: creatorfb.c fbmem.c fonts.c modedb.c sbus.c
I know nothing about the nature of the changes that have been made though!
It does seem to be a kernel problem rather than a X4.0.3 problem seeing as how 4.0.3 works fine under 2.4.2, and that using fbset on the framebuffer console in 2.4.3 solves the problem.
