With new Mageia8 have decided to tweak my video settings in both X11 and tty's to better suit my display (LCD Sanyo TV).
Supported mode for display 1360x768 was off to the left of screen by 15mm, both X11 & tty's
Fixed that by in X by using xrandr to add newmode line to the /etc/X11/xorg.conf with adjusted Hsync values (found using xvidtune)
X11/KDE screen is now correctly displayed, not off to the left.
Now I need to fix the TTY's to use the adjusted values or change to use 1024x768, as the TTY screens are still set to 1360x768 with Hsync values that display screen 15mm offscreen to the left, when I login to a tty...
In Mageia7 (32bit) when switching to the tty's (CtlAltF2), they were in 1360x768 mode offset to the left.
In Mageia8 the tty's first are in lower resolution 80chrx25line (640x480? offset to the left), and change to 1360x760 offset to left after login.
Have tried to set different Grub2 value, GRUB_GRFXPAYLOAD_LINUX=text changed to GRUB_GFXPAYLOAD_LINUX=1024x768x32
But that does not change the TTY settings after boot and using CtlAltF2 to call a tty.
So how can I get the TTY's to use the new Hsync values for VGA 1360x768 that work for X11/KDE ?
or
Change the TTY video mode to native 1024x768 that may not need adjustments to centre the display.
Suggestions welcome.
Settings that centre the display in X

xrandr --addmode VGA1 "1360x768_60_1"
xrandr --output VGA1 --mode "1360x768_60_1"
I added the new Modeline to /etc/X11/xorg.conf, along with adjustments to the Monitor section...
