? about xrandr 59.98 vs 60

[salix_user]

On Ubuntu, Austrumi (Slack based distro), xrandr shows me the current preffered mode for my notebook (1366x768) at 60.0 Hz:
$ xrandr
Screen 0: minimum 320 x 200, current 1366 x 768, maximum 32767 x 32767
LVDS1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 344mm x 193mm
1366x768 60.0*+
1360x768 59.8 60.0
1024x768 60.0
800x600 60.3 56.2
640x480 59.9
....

But SalixOS XFCE 14.2 shows me
$ xrandr
Screen 0: minimum 8 x 8, current 1366 x 768, maximum 32767 x 32767
LVDS1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 340mm x 190mm
1366x768 59.98*+
1280x720 60.00
1024x768 60.00
1024x576 60.00
960x540 60.00
......
.....
-----------------------
I am wondering why there is such a discrepancy between these outputs 60 vs 59.98 | 344x193 vs 340x190 ?

How to get '1366x768 60.00' 344x193 on SalixOS ?

It seems that the drivers in ubuntu are older. So, I'm inclined to believe that fixes have been made in the meantime and the output in Salix is the correct one.
