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.

Re: PBG3Series and pre-R5: a little bit further

[G. Laurès]

Hello *,

Batmensch : to be continued on the list

This afternoon I discovered the XF86Config.controlfb of Mr T. Oe I believe.
I tried it on my 8600, thinking it would accelerate somethings...(may be
later with the controlfb.c took at the same archive) but instead I took
some time to better use the "Monitor" statement of the XF86Config.
I set the good values for my monitor (Hitachi CM751ET) and now XFBDev
behaves slightly better to my taste.
For example I now get rid of the strange 1280x1024 real over 1280x16XX
virtual resolution of the very generic XF86Config.pmac.

Wich leaded me to this : what about if XFBDev tryied the same weird
resolutions on the poor LCD of my PBG3 ? (I use XF86Config.pmac on the
PBG3). Since the beginning I though it would be an error in the
resolution , this strange behavior of two small X screens in two
quarters etc..

I tried to include in my 8600's XF86Config the LCD settings, but I lack
some info (how to set 1024x768@60Hz)
Well, I hooked up the hitachi on the PBG3, with the SAME config as the
8600 (works here in 1280x1024@75Hz) and it didn't work.
I got basically the same error than here (no valid modes found, after
having eliminated all modes), using my half definition for the PBG3 14,1
LCD :

My question is : is it necessary to tune things to this end to get this
[snip] of XFBdev working ?
Has it already be done ? If yes where ?

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

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 !!!
