[Bug 439138] Re: [karmic] Xorg 100% CPU utilization -- only after first login

 

Tom Jaeger, did you actually notice switching VT not working?  Could
you get an strace of that happening?

Could people getting the error check /proc/`pidof X`/status?  Here I
have

SigIgn: 0000000010301000

The important part is the 3.  If the 3 is not there it's normal that
tcflush() return EIO for the console: because X starts its own session
alone, it is an orphaned group.

A good fix could be to just re-enable the TIOCNOTTY part from
xserver/hw/xfree86/os-support/linux/lnx_init.c which got dropped for no
apparent good reason, while here we have a good reason to ignore all
the controlling terminal semantic.
