Faketty 0.03 blanks screens!

[Daniel W. <dan...@te...>]

Hi folks,

We have been using multiuser desktops for more than a year here at the=20
University. We actually use multiuser X Terminals (diskless) and soon=20
they will be installed in more than 2,000 public schools (about 11,000=20
four-heads).

We use the SiS video cards, since it has been the most stable (NVidia=20
crashes after some X reinitializations or after half hour of xscreensaver=
).

I'm trying faketty now, with kernel 2.6.13.2, and had a strange problem.=20
After some minutes, all screens got black, and the only way to recover=20
was to restart the X server. But the X was running normally, just that=20
the video signal was lost.
Then I=B4ve put one X running uppon vt07, and the others at vt5[1-3] and=20
the problem was gone. System is up and running.

So I thought it might be that the kernel is sending a VGA DPMS signal to=20
my video cards, since nobody is using any of the initial tty. Am I correc=
t?

And how does the vt07 get the right keyboard, since it is assigned by=20
faketty to vt50 (that is not used by any X)

Would it help if I use faketty on vt07-vt10?

Thanks,
Daniel

Yes. Kernel blank text console, because TTY layer stay in text mode.

That vt50 is for X only. X understand only /dev/ttyXX numbers

Use on X via normal /dev/tty7, as You note above.
