I have a SIS 771/671 graphical card on my laptop, and till now I've just got the conviction that it just does not works very well on Debian 7.0, Linux Mint 16, 17 and some old Ubuntu versions. From that post we see that I'm not alone and it does not works well on Lubuntu. It's easy to deduce that Debian based system does not works good with that graphical card. So, have someone a suggestion for some distro that may be more efficient with SIS 771/671?
I recently refurbished a Fujitsu-Siemens Esprimo Mobile v5535 laptop (specs here: https://www.notebookcheck.net/Fujitsu-Siemens-Esprimo-Mobile-V5535.9149.0.html) which sports a SiS Mirage 3+ 672MX graphics chip.
The goal was to install some lightweight Ubuntu 18.04 variant (32-bit or 64-bit, Lubuntu or Xubuntu to be exact).
After trial and error for 2 days and lots of expired/non-working URLs in various forums, I found the correct driver for SiS 671/672 graphics.
The actual working driver is located here: https://github.com/rasdark/xf86-video-sis671
And I have created a bash script to help others on quickly installing the driver here: https://gist.github.com/fevangelou/46a2885233c45011ad5c8752f18eac73
Installed successfully with Lubuntu 18.04 32-bit and Xubuntu 18.04 64-bit (kept this one in the end).
Mageia has working drivers for this card. You can even get them from there to use it a distribution which still uses X.org 1.15.
See the (Portuguese) blog post http://www.vivaolinux.com.br/dica/Configurando-SIS-67172-no-Ubuntu-1404.
I was also struggling with same issue on friends laptop Fujitsu-Siemens Esprimo Mobile v5535 .
Install xubuntu 18.04.1:
Download & unzip driver from Portuguese page :
it comes from https://www.vivaolinux.com.br/artigo/Como-instalar-o-driver-da-placa-de-video-SiS-771671-no-Ubuntu-1804?pagina=2 ( it is similar to what @Jodka pointed out but bit newer for ubuntu 18 04, this page had important hint for me to test solution from person "hmslima" +thank you "hmslima" and google translator ! oh and also thank you to "TheSawage" who send this page in the comment from the @fevangelou script )
- as admin run file manager $>sudo thunar (or other file manager)
and copy and paste the xorg.conf file from the unziped dir to the /etc/X11/ and copy sisimedia_drv.la, sisimedia_drv.so to /usr/lib/xorg/modules/drivers/ and restart laptop
So Core finding for me is that you have to stick with 18.04.1 Ubuntu/Xubunut/Lubuntu versions if using above ZIP. If using newer > 18.04.1 the script made by @fevangelou will not work , also Portuguese blog posts will not work. At least i could not get it working under Ubuntus 20.04 & 18.04.4 , also i raised the issue for driver developer(s) that @fevangelou uses in the script
all the best,
