Asus 1201K (Sis chipset)
« on: February 08, 2016, 06:28:39 am »
Maybe I should have kept my big mouth shut, but now I got an Asus eeePC model 1201K in my hands. The owner wants Peppermint 6 on it. The  Athlon XP processor (32-bit) doesn't pose a threat, but the motherboard is based on the infamous SiS chipset / video.  Peppermint installs OK, but video is lousy and 'stretched'. The right resolution (1366 x 768) can't be selected.

I tried a few things already. Most documents on the WWW give the advice to go back to distros based on 12.04 LTS, after which a few teaks should get it to work. So far no luck with that. This time I'm going to try again with peppermint 6, and follow the steps in this document: http://zatherz.cba.pl/sis/.

If anyone ran into this before: advice will be appreciated.

I have nothing with an SiS chipset so can't really help here (no way of testing) .. but if you manage to get it working, we'd certainly appreciate a "how to" ;)

First of all I'm not smart enough to help you with this problem... but anyway...

On another forum I found a topic about this "same" SiS chipset/video problem.
Some links in that topic could be interesting for you? Click and Click!

Please treat this as extra info and not as advise!  ;)

OK, the Asus 1201K netbook works with Peppermint 6.

- I tried every solution I could find on the WWW. None of them worked with distros based on Ubuntu 14.04. Some did work with earlier versions.
- What did work in the end was using the VESA driver and make my own xorg.conf.

After a few days off 'trial and error', I've got the Asus 1201K running at a decent resolution: 1280x768@60Hz. The resolution *I thought* should be possible (1366x768) isn't. Normally if you deviate from the optimum resolution you will notice some degradation of sharpness. This is not the case, which led me to believe that 1280x768 is indeed the resolution you should aim for on this netbook.

While xorg.conf isn't used anymore these days, it is still supported. These are the contents of my xorg.conf:

Copy this into your editor and save it as xorg.conf. Copy the file to /etc/X11 and reboot the system.

I hope this helps other people with computers using the SiS chipset. Although I didn't test it, I'm convinced that it will work with other 14.04-based distros as well.

Nice, thanks for the solution Capivara .. we've had a few people ask about SiS chipsets and so far we've been unable to help, so this will come in VERY handy :)
