Problems with running X on NEC Versa P/75

Problems with running X on NEC Versa P/75

Post by Chuck Matter » Fri, 27 Mar 1998 04:00:00



I'm setting up X on a NEC Versa P/75 with a ct65545 video controller.
I found the references to setting it up on the Linux Laptop home page
and the result is very nice except that the right fourth of the screen
is blank.  xvidtune does nothing for me.  Can anyone share a working
config file with me or point me in a direction on how to get this
working?

Regards,
Chuck

Following up on myself here I've set up a supposedly identical Versa
P/75 with the same XF86Config file and the blank section is not
present.  Both units worked fine in their previous configuration with
Win95.  The only difference I can find is with the output of
X -probeonly:

$ diff foo.good foo.bad    
65d64
< (--) SVGA: oak: OTI-57 unsupported.
72c71
< (--) SVGA: CHIPS: Display Size: x=640; y=480
---

Quote:> (--) SVGA: CHIPS: Display Size: x=712; y=600

76d74
< (--) SVGA: CHIPS: Internal DAC disabled.

So it would seem to me that the issue is the Display Size setting,
although 712x600 is a bity odd could kind soul tutor me on a modeline
that would do the trick there?

I attempted to alter the 640x480 line that works but when I do so this
mode fails with a message indicating that it needs a hsync freq of
30.55.  Any suggestions?


Modeline "640x480"     25.175 640  664  760  800   480  491  493  525

Modeline "712x600"     25.175 712  736  784  824   600  611  613  645

Chuck -
I've got XFree3.3.1 running at 16-bit colour depth on an NEC Versa 4050H -
it's at 800x600 since this is the highest resolution my TFT screen supports.
I don't know whether or not the hardware is exactly the same as your model,
the video chipset in mine is CT65545 based.
In any case, I've taken the liberty of attaching my complete XConfig file so
that you can look it over. Good luck with it - I hope you get it up and
running because it works superbly. The only thing I've not bothered with is
getting the source and looking at making the tapping on the glide-pad
implement a left-button push.

Cheers,
Steve

I am looking for what PCMCIA CD Rom drive to buy for a NEC Versa P/75
that has drivers that will let me load linux from a CD Rom onto
my laptop.   Or is there a way of hooking a CD Rom drive up to a laptop
that will let me install linux.

Thanks for any help on this.
