Demonstration of the problem:
# vidcontrol VGA_90x30 < /dev/ttyv0
Alt-F9 to switch to XFree86
Alt-F1 to switch back
The screen is now in 80x25 mode, but it thinks it's in 90x30, meaning that
each line is offset by 10 characters.
However, after the screen saver has activated and then been deactivated, the
vidcontrol settings are restored.
Looking at the XFree86 source, when switching away it does this:
ioctl(xf86Info.consoleFd, VT_ACTIVATE, key - KEY_F1 + 1);
Looking in src/sys/dev/syscons/syscons.c for this ioctl, we have:
return sc_switch_scr(sc, i);
sc_switch_scr doesn't ever seem to call scrn_update which restores the screen.
Can someone who is a syscons expert have a look at this? I've submitted it as
a bug with id kern/48777.
Thanks,
Phil.
