sisfb: two more little problems

sisfb: two more little problems

[Torrey Hoffman]

Besides the problems with mode switching with fbcon, I have two other
problems with sisfb:

1. My gpm mouse cursor on the framebuffer console is a cyan rectangle
with a bright orange "G" in it.  Actually the G has a "^" accent over
it.  That's just when it's over a blank spot.  When I move it over other
characters, the character in the pointer changes.  However, it does work
for selecting text.

2. I can't seem to set the default video mode from the kernel command
line.  I have tried:

video=sis:1024x768-24@75
video=sisfb:1024x768-24@75

and neither one works.  What is the expected command line?

Thanks,

Try my latest patch. It should fix this.

Let me know how it works out for you.

It is video=sisfb:...

Hm. It should work.

The sisfb parameter syntax is a bit tricky, it's explained at the
maintainer's website:

Well, not quite.  The problem is still there.  I have checked it a
little more closely though, and noticed that it isn't always there. 
Some virtual consoles have the problem and some don't.  It seems like
before I log in on a console, there's no problem.  And sometimes even
after logging in it is OK, but usually after I log in the green and
orange framebuffer mousepointer starts.

This is Red Hat 8.0, by the way.  I think it does something to the
console when I log in, the screen usually blanks for a second after I
enter the login password and before the bash prompt appears.

I found the sisfb web page and it is:
video=sisfb:mode:1024x768x24

and that works, but only at 60 HZ.  I haven't tried putting a "@75" on
the end yet...

Thanks again!
