They might regarding suspend/resume video, but no, not for this one ..

Sorry, I was mistaken .. I've still got this problem too.  Once I got
suspend/resume going I hadn't quit X in more than a month.  Tonight I
did, to check, and there was the blank screen again. 

So I resorted to my old workaround, which may also work for you; I just
type 'fixme' at the unseen vty prompt: 

t23# cat ~/bin/fixme
# strangely enough, this invalid mode restores vttyX with the error message:
# vidcontrol: cannot activate raster display: Inappropriate ioctl for device
vidcontrol VESA_800x600

Bizarre, but the only way I found worked, by accident.  Valid vidcontrol
commands failed to achieve this for me, but I know very little magic ..

Earlier I'd found that setting one vty with 'vidcontrol VGA_80x30'
before starting X helped if I switched back to that, but only running
'fixme' saved me tonight.  It's evil, but sure beats rebooting ..

If you have access to a windows box to burn the floppies and a USB
floppy drive, or Windows on the T23, you're set.  I have neither yet.

Mailed separately.  At least X hasn't crashed on me yet with that conf.
