Xconfigurator hangs probing monitor info
Last modified: 2007-04-18 12:29:48 EDT
Frequently, when I run Xconfigurator --preferxf4, it freezes the machine
solid while trying to scan for monitor parameters. It doesn't seem to
matter whether I have X running on another console or not. It has never
done this the first time I've run it after boot.
What card type?
My video accelerator is a Matrox mgag200 AGP, 8mb
I got it to crash again, this time with a strace. It seems to go into an
infinite loop calling vm86 and recieving 'function not implemented' from the
kernel. after a few seconds of this scrolling by, the system locks with no
sysrq, as mentioned before.
some combinations of hardware do not like to be DDC probed. This will probably
not get fixed (You can choose not to probe) until a rewrite of Xconfigurator
