Hi. This is indeed a setting in xorg.conf, however, this part in the dmesg is
new:

[    2.073595] [drm:drm_mode_debug_printmodeline [drm]] Modeline 63:"2560x1440"
60 241500 2560 2608 2640 2720 1440 1443 1448 1481 0x48 0x9
[    2.073600] [drm:drm_mode_prune_invalid [drm]] Not using 2560x1440 mode:
CLOCK_HIGH

It seems to try and validate my modeline but discard it as invalid. 

I will try and use xrandr right away.
