Solution

fixed by using

sudo -H gedit /etc/default/grub

locate line #GRUB_GFXMODE=640x480

delete the # and replace 640x480 with 1024x480

sudo -H gedit /etc/grub.d/00_header 

find line gfxmode=(grub_GFXMODE) and under that add

set gfx payload=keep

Ran sudo update-grub

then ran xdiagnose from dash checked all debug options

It worked wonderfully! For the record, my graphic card is an integrated VIA chipset CN986/VN896/P4M900 [Chrome 9 HC]

For me line is like set gfxmode=${GRUB_GFXMODE} , so set gfx payload=keep will come under this line ?
