[Solved] Old Thinkpad Laptop with HPA LCD + SM712

I have some problem configuring X on an old laptop (IBM Thinkpad 1161-237 i series 1200 with an HPA LCD 12.1" 800x600 max resolution) ... I tried everything.
I can start X, but I have a mess on the screen ... you can see the windows, but there are lines and pixel with randon colours everywhere. In other words a mess.

I have a backtrack live cd, so I tried to see if the same problem come up with it: absolutely not, everything was fine. So, I checked up how backtrack configured X ... and I saw that it generated a xorg.conf file on the fly .... well, here we go I said. I copied that file on a usb stick and I putted it in the /etc/X11/ directory of arch .... startx ... and ..... same mess.

The video driver is siliconmotion ... and everything is up to date.

                             Thanks in advance

PS: Obviosly I tried to use the various configurator ... the results was X up with black scree during the configuration but the file was generated ... using this one, same mess I told you above.
Last thing. I also use hal (it starts from rc.conf at start up).

Which driver are you using?

As I said siliconmotion ... the card had a chip LynxEM4+ from silicon motion

Still no ideas?

How could it be that the autogenerate backtrack's xorg.conf doesn't work correctly in arch?

It's the exactly same machine, same configuration ..... I'm absolutely confused.

It doesn't make sense to me.

It starts X on arch with that xorg.conf, but the screen is completely messy ...

meanwhile I've tried also hwd and other tools .... there is no way ... :-(

I wanna try to downgrade x server.

Where can I find old arch repositories (extra in particular)?

I see that backtrack run a 1.3.x version of X, arch 1.6.x ...

Re: [Solved] Old Thinkpad Laptop with HPA LCD + SM712

I found out that the video card run at MCLK 157.000 in arch vs 85.909 in backtrack ...

I tried to use SetMClk option in xorg.cong but it was ignored ...

how come?

[Problem Solved]

The option to use is:

Option "mclk" "85.000MHz"

Silicon Motion driver 1.7.3-1 put mclk at 157MHz as default value, memory can't support this frequency

signal that as a bug please.
