Using the "vga" driver, however ugly the display is, does not panic the kernel. The last time I tried 4.0.2 before this latest attempt, I also tried the "i128" driver, which the website says is a Number Nine driver. It didn't work either, causing a kernel panic/reboot. Elsewhere in the website it clarifies that this driver is intended for Imagine-128 chipsets. More information will follow as I learn more about X 4.0.2, including further bug reports, if they seem necessary. >How-To-Repeat: You'll probably need an IBM Aptiva and/or a Number Nine SR9 video card (which is out of production anyway). Compile X 4.0.2 from ports, create a config file with xf86cfg, and substitute either the "savage" or "vesa" driver in place of the "vga" driver in the file. Try to start X either as root, or with Xwrapper, and it should panic the kernel (at least, it causes the system to reboot, you never actually get to see the kernel messages as the console does not switch back to where the messages are appearing). You may also be able to crash the machine simply by running xf86cfg without the -textmode switch. In my setup, this will crash the machine. If you force text mode with the above mentioned switch, xf86cfg does create a config file which does work, albeit only in 320x240/8-bit and 640x480/4-bit modes. >Fix: No idea. Using the "vga" driver provides a temporary solution, however by the nature of the vga driver, no accelleration or high-quality displays are available in this mode. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ports" in the body of the message
