How can I get the log files?
I'm trying to install Ubuntu 10.04 on an LG R450 laptop with sis671/771
thank you.

The log is located at /var/log/Xorg.0.log, use a live disc or the minimal graphics recover system thing if it works to copy and paste the log...
BTW: Which resolution do you want to use?

So, your xorg.conf is wrong, check this post to get a full explaination of how to set it up right: http://ubuntuforums.org/showpost.php...&postcount=371

I'm sorry, I do not know a clue... I think you have to manually define modlines as the default modlines were not excepted by Xorg for unknow reason...
I don't know how to fix this

Hi, Jonas

Tried yuor mod, in my system it should be paired with the previous fix:

as root (su)

#echo blacklist vga16fb > /etc/modprobe.d/blacklist-vga16fb.conf

and then

#update-initramfs -u

the terminals look good.

Just to make it a little easier for all of us;
btw:Thx @purct and @ajoliveira

Hey, should add thanx @gh1234, he pointed me to a stupid mistake I was making when trying to compile the new driver and was the first to get it on Lucid 32-bit

If you use sis 2d linux driver with panel size 1366x768.
You MUST enable the option UseTiming1366 like bellow:

Section "Device"
Identifier "Configured Video Device"
Driver "sis"
Option "UseTiming1366" "yes"
EndSection
