    Ubuntu 19.04 DD low resolution

    Hi, I've recently installed Ubuntu 19.04 Disco Dingo. The maximal resolution that I can set is 1600x900, while I can set 1920x1080 in Windows on the same pc. My graphics card is GTX 660, I am using official NVIDIA drivers. The display is plugged in through the VGA-DVI adapter. I've tried adding new mode in the xorg.conf file. In addition, when I was installing it, i had to use the safe graphics mode as in the normal one there was nothing but a black screen. What can I do with that? Not only that, using noveau drivers resulted in the same.

    OK so you did the xrandr steps in the tutorial...

    question: in step 5 of the tutorial did you enter the values generated by step 4....or did you enter the values
    shown in step 5 of the tutorial ??? the values shown in step 5 may not be the same for your PC....

    the xrandr values you listed shows the display is capable of 1600 x 900 resolution, but is currently at 1024 x 768...

    BTW...when listing a set of values in your reply, please use code tags to make the response more readable...use the ADV Reply
    button, select the # character and paste the values between the # characters...

    Yes, as I mentioned in the previous post I pasted my own values for 1920x1080x60. The actual resolution that is set in the settings and in the driver as well is 1600x900. Thanks for advice concerning listing values

    can you post the results of

    Code:
    inxi -G
    it might look something like mine

    Code:
    [tommy@tommy ~]$ inxi -G
    Graphics:
      Device-1: NVIDIA C61 [GeForce 6150SE nForce 430] driver: nouveau v: kernel

    Re: Ubuntu 19.04 DD low resolution

    your list of the output of xrandr looks suspicious....

    you say that you followed the steps in the post you referenced to get the resolution to 1920 x 1080.....
    but your list of xrandr output does not show any 1920 x 1080 mode...there is no mention of the screen ID,
    min/max resolution, and it shows your monitor size as 0mm x 0mm.....how could it possibly be seen...

    see my output of xrandr below

    Code:
    [tommy@tommy ~]$ xrandr
    Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 4096 x 4096
    VGA-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 1600mm x 900mm
       1920x1080     60.00*+
       1366x768      59.79  
       1280x800      59.81  
       1280x720      60.00  
       1024x768      75.03    70.07    60.00  
       800x600       72.19    75.00    60.32  
       640x480       75.00    72.81    59.94  
       720x400       70.08
    you may need to redo the procedure & tell xrandr to enable the new mode

    I would redo everything starting with

    Code:
    cvt 1920  1080
    and then do

    Code:
    sudo xrandr --newmode "1920x1080_60" then the rest of the values generated by the cvt
    then do

    Code:
    sudo xrandr --addmode DVI-I-0 "1920x1080_60"
    finally do

    Code:
    xrandr --output DVI-I-0 --mode 1920x1080
    if everything went correctly, you should see the resolution change

    good luck

      Major opcode of failed request:  140 (RANDR)
      Minor opcode of failed request:  16 (RRCreateMode)
      Serial number of failed request:  54
      Current serial number in output stream:  54
    when I entered text in the step 2 like that

    Code:
    sudo xrandr --newmode "1920x1080_60" 173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
