I think the recent addition of the ability to call real-mode BIOS functions should allow the console drivers to re-initialize the graphics card for text mode, shouldn't it? Søren, i'm probably even interested for a common solution for pcvt and syscons here :), albeit i haven't done anything on pcvt for years now. Sure, that's a one-way street, with no chance for the Xserver to regularly continue its work in graphics mode. But in the case of a panic, that's a moot point anyway. It should be possible to kill -9 the process holding the VTY in `process mode' from within kernel context, so that even in the DDB case (where some operator _could_ continue the kernel after fixing the panic condition manually, and walking up the stack ;-) the Xserver would not continue at all. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
