This may not be relevant, but I have a functioning SC console and X with
a system that is similar to yours. X will exit cleanly and can be
restarted without issue.
The only video task that can not be performed is cleanly switching
between X and SC. I can switch from X to SC but the system will freeze
when trying to switch back. Consequently when I must work within a
console I exit X. This is not much of an issue as I use xfce4 which, as
you probably know, is rather light weight.
The hardware is a multi-core amd64 CPU with a low-end Nvidia graphics
FreeBSD is 10.3-RELEASE-p21 with a custom kernel. The graphics
driver is nvidia-driver-384.59 installed using the pkg system.
The loader settings related to graphics:
The kernel settings:
# atkbdc0 controls both the keyboard and the PS/2 mouse
#device atkbdc # AT keyboard controller
#device atkbd # AT keyboard
#device psm # PS/2 mouse
#device kbdmux # keyboard multiplexer
device vga # VGA video card driver
options VESA # Add support for VESA BIOS Extensions (VBE)
#device splash # Splash screen and screen saver support
# syscons is the default console driver, resembling an SCO console
options SC_PIXEL_MODE # add support for the raster text mode
# vt is the new video console driver
#device agp # support several AGP chipsets
As the system has a USB mouse and keyboard the AT and PS/2 settings
were commented out. Some time ago I experimented with VT and decided
it was not ready for prime time; essentially for the same reasons you
previously described. Thus vt and agp were also removed.
Vga and VESA were kept as I have an LCD monitor and the video mode can
be set with vidcontrol during user login. The video mode for root is
The rc.conf settings:
I prefer Swiss fonts as they have a clean uncluttered appearance.
And finally .cshrc in my home directory.
vidcontrol -g 100x37 VESA_800x600
X is started with startx.
xorg.conf is a fine tuning of the initial settings provided by
These settings may not be relevant to your situation, but I am passing
them on in case something does. If I misunderstood your original
posting I apologise for this noise.
