display resolution - XRandR cannot add the mode - Ask Ubuntu 


root@localhost:~# xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync x error of failed request:  badname (named color or font not exist)   major opcode of failed request:  140 (randr)   minor opcode of failed request:  16 (rrcreatemode)   serial number of failed request:  33   current serial number in output stream:  33

it working fine previous kernel broken.

edit 1: think possibly reason behind problem required resolution has somehow got transferred new display name virtual1. below screenshot of xrandr -qenter image description here

so if tell me how delete virtual1 display unable to, think do.
