Hi OK I did not search for that V022 bit so believe you.
Now can you explain why you elected to use Vesa in your xorg....so assume you manually editted to force vesa from reading that other link?
2) I don't use Gallium myself but lets confirm you still have the sis driver available pls try this as local user
dpkg -l | grep xserver-xorg-video
You should have a hit for the vesa and hopefully one ending is sis.
Now leaping ahead if you have the *-sis package, hopefully you will have the sis driver already loaded altho IMHO its not used in your xorg
Check it like this pls
lsmod | grep sis
####and
lspci -vvv
see below ####
As I am not a sis expert here is my links but don't try Arch stuff as we are different pls
https://wiki.archlinux.org/index.php/SiShttps://en.wikipedia.org/wiki/Gallium3Dhttps://sites.google.com/site/easylinuxtipsproject/sis^^ last link is only for 671 or 771 cards.
what I plan on suggesting is you manually changing your xorg after making a backup to change from
vesa to sis or someother sis like module
### this is the below
the kernel module loaded may not reflect what is available so I am guessing here OK
lspci -vvv .....copy and paste just your VGA stuff I will show mine to give you a clue
....00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06) (prog-if 00 [VGA controller])
cull the junk
Kernel modules: i915......Yours will be either vesa or a sis type result
