Today I played a bit with Vortex86sx based device again. This time I wanted to get X11 working on it.

In short: it “works”. Default driver should be “sis” but it fails with messages which shows that libpciaccess has a problem on that device:

(EE) SIS(0): Unable to map IO aperture. Invalid argument (22)

I switched to “vesa” driver — it works, gives 1280×1024 resolution. But it is so sluggish… Even my few years old Zaurus c760 is faster (I checked how Vortex86sx works with VGA resolution).

Tried also “fbdev” driver — same slowness. All was done with full X.org server not “kdrive” one.

    I am using vortex86sx with debian lenny, and here SIS driver is working smoothly since I was using kernel 2.6.26

    I suggest to look at http://www.dmp.com.tw/tech/vortex86sx/.

    Please note, ethernet driver provided don’t work with recent kernel, but it’s not a real problem. Starting from 2.6.27.13 r6040 stock driver works just fine.

    I hope it help
