get full HD resolution

[jdd at dodin.org]

Hello,
I use openSUSE and have already asked on openSUSE forum with no result 
so far.

The problem details are here, I can copy then on the list if asked to :-):

https://forums.opensuse.org/showthread.php/528183-Get-a-HD-resolution-on-reluctant-hardware

summary is I expect my hardware LCD to be full HD 1080, because I got 
full HD working during a week or so, but an update killed the process 
and I then can't get more than 1366x768 :-(.

the computer is an ASUS N550JK, optimus, graphics:

NVIDIA® GeForce® GTX850M 4 Go DDR3
INTEL i810 HD graphics 4600

nothing in the bios to activate/deactivate any one. Bumblebee seems to 
works.

I *can* have full hd on external TV that needs tweeking with xrandr, but 
on internal I get

xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 
1083 1088 1120 -hsync +vsync
xrandr --addmode eDP1 1920x1080_60.00 

X Error of failed request:  BadMatch (invalid parameter attributes) 
 

   Major opcode of failed request:  140 (RANDR) 
 

   Minor opcode of failed request:  18 (RRAddOutputMode) 
 

   Serial number of failed request:  39

thanks
