Ubuntu 18.04 cannot run FULL HD monitor connected with VGA on its full resolution [closed]

I have a problem with Ubuntu 18.04. I have a laptop and 2 external monitors connected to it. The first one is with resolution 2560x1440 and it is connected via HDMI cable. The second one is 1920x1080 and it is connected via VGA cable (because the laptop has 1 VGA port and 1 HDMI port). So when I open Displays in Ubuntu it shows me the right resolution for the monitor with resolution, but is shows me 1024x768 for the second monitor (which is connected via VGA cable). I had the same problem with mint 17.3. I solved it in Mint with this approach (of course for FULL HD resolution) and after that I executed
sudo xrandr --output VGA-1 --mode "1920x1080_60.00" --verbose
So I execute
sudo xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
sudo xrandr --addmode VGA-1 "1920x1080_60.00"
sudo xrandr --output VGA-1 --mode "1920x1080_60.00" --verbose
everything was fine. But on Ubuntu 18.04 the last command failed with the following message:
crtc 2: 1920x1080_60.00 59.96 +342+0 "VGA-1"
xrandr: Configure crtc 2 failed
crtc 0: disable
crtc 1: disable
crtc 2: disable
crtc 3: disable
crtc 4: disable
screen 0: revert
crtc 0: revert
crtc 1: revert
crtc 2: revert
crtc 3: revert
crtc 4: revert
So my FULL HD monitor can run in at most 1024x768 now which is not cool.
So does someone have an idea what's going on? How can I resolve this? I didn't install any drivers manually so if you want some information about the drivers you can tell me how to check them and I will provide you the output.

This is on Intel video, I presume? You didn't mition which GPU your system is using. However, this sounds like a driver bug.

@dobey, when I executelspci -vnnn | perl -lne 'print if /^d+:.+([S+:S+])/' | grep VGAthe output is00:02.0 VGA compatible controller [0300]: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06) (prog-if 00 [VGA controller]) 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Mars [Radeon HD 8670A/8670M/8750M] [1002:6600] (prog-if 00 [VGA controller])so I think that both of the GPUs are used.
