[9fans] intel chipset graphics controller

[Yoshi Rokuko]

Hey folks,

yesterday I installed Plan 9 to my ThinkPad (X30) and the graphical
installer worked fine (with 1024x768x8 and xga). And now if I first login
with user glenda the display gets fading green into purple - looks scary.

I had this once with a wrong or old/buggy intel driver under linux also ...

Can't I just use the driver like in the installer?

Regards, y0shi


Here is what linux tells me with lspci:

setting "monitor=vesa" would probablly do the trick.

than I have a probably easy question: how can I get into the system and
edit plan9.ini in order to add monitor=vesa?

I know this (see down below), but how do I get there?

9fat:
sam /n/9fat/plan9.ini

Thanks again, regards,

i'm not sure what the problem is here.  can you not view the screen?
assuming that's the problem, you could
* enter a bogus monitor & resolution if prompted
* boot from livecd.  if /dev/sdC0/9fat doesn't appear
   you may need to run
	cd /dev/sdC0
	disk/fdisk -p data>ctl ; disk/prep -p plan9>ctl
  first
