SiS Graphic Card Support (771/671 PCIE VGA)

[lidiaz]

Hi!

It's my first time using linux and I know nothing about driver installing.

I have an issue with the display resolution (it gives me no video options) and just found out there's actually an incompatibility between some Ubuntu-based distros and the SiS Graphic Cards, specially the 771/671 version.

For some versions of Ubuntu I found the support, but simply couldn't understand it!!!

Does anyone knows if Linux Lite 2.0 has any kind of bug fix, update or anything that could be done to install this SiS graphic card driver?
And, if so, would anyone please try to explain it in a way that a linux begginer completely dummy could understand? =D

Thanks a lot!
Sorry for the bad english..

Go to Menu > Settings > Install drivers and check if there are any proprietary drivers to install.

What resolution do you want?

Hi I'm attempting to install LL2.2 on an Advent K1301 which has the SiS chipset in and have same problem low resolution.
Going to give 2.0 a try to see if that will work.

Just tried 2.0 and same.  Live works with a high resolution but when installed goes to 640x480 and no alternatives.
Could I ask why it seems to be okay in live but then not when installed?

Yep it's  SiS Graphic Card Support (771/671 PCIE VGA)

Still don't understand why it works on live but fails to when installed. 

I understand from other sources that 12.04 should work so which LL is based on this.  is it 1.8?
Thanks

Linux Lite 1.0.8 is Ubuntu 12.04 LTS based.
However, before installing LL 1.0.8, you can try creating xorg.conf file as suggested in the link I've posted.
Open a Terminal and create a xorg.conf file

Code:

sudo leafpad /etc/X11/xorg.conf

It will open a text editor with elevated user privileges.
Now copy and paste this configuration in it

Misko thanks for the info, especially the simple way to do it.  People sometimes forget that novices sometimes need to be spoon fed a little early on. 
Thanks again.

Happy Holidays.
