Sorry, I added earlier the drm.debug parameter during the boot in the
grub menu hitting 'e' but probably I did it a wrong way.

Now I attach the new dmesg.txt with drm.debug=0x04.

I can confirm that the monitor is connected on the VGA port (there is no
other possibility to connect it to the graphics card).

Unfortunately, I can not provide the output of xrandr because I get the error: Can't open display (because I have no any running X I can get only a text console (see below)).
If I run xrandr remotely (without setting the display) I obtain the followings:
 SZ:    Pixels          Physical       Refresh
 0   1024 x 768    ( 347mm x 260mm )   60  
 1    160 x 120    (  54mm x  41mm )   60  
 2    320 x 240    ( 108mm x  81mm )   60  
 3    640 x 480    ( 217mm x 163mm )   60  
 4    800 x 600    ( 271mm x 203mm )   60  
 5   1680 x 1050   ( 569mm x 356mm )   60  
*6   1670 x 971    ( 566mm x 329mm )  *60  
Current rotation - normal
Current reflection - none
Rotations possible - normal 
Reflections possible - none
Setting size to 6, rotation to normal
Setting reflection on neither axis

Some other information:
If I hit esc when grub starts and I check the boot parameters with the key 'e' and 'ctrl+x' to continue the boot process I will obtain the possibility to log in on a text console which I can exploit maximally. During the boot I can see the boot messages and finally gpm (mouse in a text terminal) works as well. Logging in and trying to start gdm I get the warning along with similar warnings:
GdmLocalDisplayFactory: maximum number of X display failures reached: check X server log for errors

If I do not touch the computer during the boot (or hit esc to see the
grub menu but continue booting with enter) I will get a black screen
with a blinking cursor in the upper left corner and suddenly I can see
the Ubuntu splash screen for a second and finally I get a totally black
screen. (No any boot message was seen.) In this final state I can not
switch to a virtual terminal by hitting Ctrl+Alt+F1 or F2 etc. I can
reach the machine only by ssh (ssh-server is installed) or through a
graphical application like nx-client from a remote machine. If I login
by ssh and issue the command 'sudo reboot' or 'sudo poweroff' the ubuntu
splash screen appears immediately and reboots or shutdowns the computer.
