[Tfug] (return to) grub question

[Joel Howard]

Thanks Stephen, Matt, John for the continued feedback about grub.

The documentation for grub is pretty short and stark -- The 
clarifications on altoptions and kopt are greatly appreciated and will 
go into my master Alzhiemer's notebook. Regarding XFree log file, mine 
looks mostly clean -- no EE errors or WW warnings present, though the 
output is extensive. Something looks fishy about this big long repeated 
discharge at the end of my XFree86.0.log (not all of it shown here). Who 
knew computers could be so indecisive? Is GrabKeyState for mouse? in the 
kernel? BTW I've recompiled this kernel several times if that's what you 
mean by a custom kernel. Other than that it's just kernel 2.6.11.

Here's what might be working -- my syslog and messages have been free of 
"dazed and confused" message for about 24 hours now (yippee) :

#/etc/init.d/gpm stop

The gpm mouse driver for my tty consoles may be interfering with psaux 
driver used in X. Stopping it has stopped the weird message, but of 
course now the consoles have no mouse (no biggy). I think I'm getting 
warmer on this problem!
Thanks again,
JH
