When using a dual-head or twinview configuration on a single GeForce 4 Ti4200
board, X11 starts up properly and no error messages are given; both the main CRT
and TV function properly as independent displays. However, VT-Switching, manual
restart of X (CTRL+ALT+BS), or ending a GNOME session always result in a blank
screen on both displays, complete lockup of all input. Only a hard reset on the
Steps to Reproduce:
1. Use the latest stable packages for xorg-x11, gentoo-sources, nvidia-kernel
2. Configure Xorg to use either a TwinView configuration or two separate
displays, one of which uses TV-Out.
3. Once X has successfully displayed a login screen, change to virtual console,
use CTRL+ALT+Backspace or exit a GNOME session (after logging in).
Complete lockup of system. Only a hard reset makes it usable again.
Either shut down properly, display the proper virtual console or exit cleanly of
the current gnome environment.
Using the following ebuild versions: xorg-x11-6.8.2-r4,
gentoo-sources-2.6.13-r5, nvidia-kernel-1.0.6629-r6, nvidia-glx-1.0.6629-r4.
Also happens with latest unstable nvidia-kernel and nvidia-glx versions.
Disabling any framebuffer support, switching from kernel AGPGART to internal
NV-AGP have also been tried to no avail. This issue only seems to appear on
GeForce 4 Ti4200 boards, though some other GeForce 4 variants may be affected.
From information found online, this may be a new issue related to newer linux
kernels and/or nvidia modules. Board is ASUS make, not sure exact name. Uses
GeForce 4 Ti4200 chipset, 128 Mb RAM.

Has this ever worked for you?

Well, I've installed Gentoo only recently, so I've had the problem since day
one, yes. The only thing I can say is that I used SuSE 8.0 Professional a few
years ago and never had X crash using TwinView. Then again, it was under XFree86
and a 2.4 kernel, but I *was* using the official closed nVidia drivers. Which is
to say, the card isn't defective, and TV-Out works perfectly under Windows 2000
with the nVidia drivers.
xorg-x11-7.1 is the oldest in the tree atm.
