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 computer works. Reproducible: Always Steps to Reproduce: 1. Use the latest stable packages for xorg-x11, gentoo-sources, nvidia-kernel and nvidia-glx 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). Actual Results: Complete lockup of system. Only a hard reset makes it usable again. Expected Results: 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?
(In reply to comment #3) > 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.
