I think I loaded all the mesa libs for :
gl, glx, dri, mesa common and mesa utils
You just have to wait a minute (or 2 ) , then X will get running in vesa mode, .. so you can install.
Ater that; read my step-by-step guide..;
and all should be working out for you.
Edit; @jodlajodla.. Seems you've found my guide yourself.. and you got it running..nice.
I just found out the driver I compiled (but not the previous one) does not load properly when acpi is on and I am investigating why...
http://download.dekoderek.net/sis-on...purct/make.log (it's too long to put it here). There are also some warning during compilation. I added some other -dev libs I thought might be useful but that didn't help.
Also running ./autogen.sh --prefix=/usr broke the sources. I had an error: http://download.dekoderek.net/sis-on...ct/autogen.log and since then I couldn't run make again. Even after make clean and configure. I had to remove and unpack sources again.
sudo apt-get install xserver-xorg-core x11proto-core-dev x11proto-dmx-dev x11proto-xf86dga-dev xserver-xorg-dev x11proto-xinerama-dev libdrm-dev x11proto-xf86dri-dev libgl1-mesa-dev autoconf libtool install x11proto-gl-dev libxxf86misc-dev x11proto-xf86misc-dev
cd to src/.libs
cp sis671_drv.* /usr/lib/xorg/modules/drivers
then create a /etc/X11/xorg.conf (I have a sample one on the blog)
if you are going to create your own make sure you set Option "SpecialTimings" "ASUSX5DC"
It's 1360x768 though and I have six rows of pixels on the right unused but it's much much better than before and the notebook is usable now.
Thanks again to all of you and you can post this drivers as working on (at least one :) Asus K50c with Ubuntu 10.04.
