I ended up giving the laptop away (I was also given it), I should have tried again to center the display using the complicated xrandr scale system but none of the vga= possibilities worked and the SiS/VESA performance was just so bad.
Fedora 25 LXDE, SiS 671/771 GPU
Fedora doesn't have the "sisimedia" driver needed, people have been requesting it for the past 9 years. (Link below.)
PCLinuxOS has a new RPM but it doesn't work on Fedora 25.
By adding nomodeset
as kernel parameters I get 1280x768 on my 1280x800 display but that vertical stretch makes the display look pretty bad.
xrandr --output default --set "scaling mode" "Center"
command does not work as I don't think it supports the VESA driver? Is that correct? But there's alternative way using xrandr and the scale
From what I understand VESA can't do certain resolutions so actually getting 1280x800 is out of the question? Is that correct?
This official Ubuntu wiki page:
claims this simple xorg entry
makes all resolutions available to VESA but I haven't seen anyone in a forum claim it works and it didn't work for me.
