Re: PBG3Series and pre-R5: a lot further

[G. Laurès]

Finally, I got it !
XFBDev on PBG3 series, now the TFT screams ! I never though it would be
that good.

So it turns out that it was the lack of valid video mode that prevented
XFBDev to work properly (actually, to display properly). Now I have the
following /etc/XF86Config :

# /etc/XF86Config
# makes XF68_FBDev emulate Xpmac by using the current video mode
# and the mac mouse. be sure to compile macintosh mouse
# support into your kernel and to create /dev/adbmouse.
# major=10 minor=10

Please note that the 3 modes defined for the LCD are taken from a
Toshiba laptop screen... I didn't had enough info to build the right
ones, however they work quite well.
Two are commented because if not, they are taken instead the 1024x768,
which is obviously nicer. I don't know why.

The server is stable now, no more freezes as before. I just lack a
french keyboard and 3 buttons and enlightenment and gnome and java and....

This machine is now really a screamer, I'd like to thank G.U. for his
amazing work, of which I can finally make some use !

The whole process to make this working from a fresh pre-R5 installation
is: (by memory)
make sure the XFree86-FBDev rpm is installed
go to /etc/X11 and there ln -s /usr/X11R6/bin/XF69_FBDev X
copy the enclosed /etc/XF86Config
startx !!!

RE: PBG3Series and pre-R5:a lot further

[Batmensch]

I tried this XF86Config on my PB G3 Series, and although it starts up, it is
still running in Open Firmware (non-accelerated mode).

Did you try running fbset -i while the Xserver is up?

I could be wrong, but it seems to me I remember reading somewhere that you
can't run XF68_FBDev in accelerated mode when the console is running Ofb.

Xpmac is much faster than Ofb; try moving an open window around.

Does the XFBDev out specifies it's using the ATY Rage PRO device, with
acceleration enabled ?

If not, try video=atyfb:vmode:14,cmode:8,mclk:83 as a kernel argument,
with unchecked "no video driver" box.

If you not see atyfb;ATY RageLT PRO in the boot sequence (and later in
/var/log/dmesg) then there is a problem.
If you do see it, then XFBDev should report it's using the ATY chip, in
acccelerated mode and things should go... lightning.

I don't have fbset unfortunately, I think I have to grab it from G.U.
site, yeah ?

Sure.

I wasn't able to make some use of Xpmac

Doesn't work; I get the "psychedelic death screen".  Strangely, if I set the
mclk to 43, the display is still messed up but I can hear the machine continue
to boot.

I don't think I've heard of anyone using atyfb successfully on a 300mhz PB G3
Series.
