I guess it is i915 --> "Intel HD Graphics". I found out the Intel software that I should install and did it :
"intel-graphics-update-tool_2.0.5_i386.deb"

But the installation does not end properly giving an error about "NO SIGNATURE" or something.

With these I cannot do something.

Please help, thanks.

Can you give the output of:

sudo dpkg -i ~/Downloads/intel-graphics-update-tool_2.0.5_i386.deb

Thanks

Sure, here what it says :

sudo dpkg -i ~/Downloads/intel-graphics-update-tool_2.0.5_i386.deb
dpkg: error: cannot access archive '/root/Downloads/intel-graphics-update-tool_2.0.5_i386.deb': No such file or directory

By the way, I had manually downloaded 2.0.5 from Intel's website. The .deb file is on my desktop. I can right click and install it but when I run it cannot complete its actions.

It even messed my apt-get update / upgrade results and I cannot even complete them any more.

Are you logging in to the system as root?

Just change the path to the deb file, you can easily change the folder name

I typed your messages as root

But I ran the software over the desktop of my Ubuntu X user which is an administrator but not root.

I tried to run the .deb it over Console:

THEN IT GIVES AN ERROR LIKE THIS (I have typed the message, coz it cannot be copied-pasted) :

W:GPG error:https://download.01.org/gfx/ubuntu/17.04/main zesty InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 611B903CAB97EA77, E:The repository 'http://download.01.org/gfx/ubuntu/17.04/main zesty InRelease' is not signed.

I could install the DEB using :

sudo dpkg -i /root/intel-graphics-update-tool_2.0.5_i386.deb

after copying the DEB file to root.

Then I ran the Intel application from X. I still get the same error as I wrote above.

There is still 1024x768 as resolution

So ?

SOLVED : I have solved the issue MYSELF focusing on "UNKNOWN MONITOR" issue here.

I knew the 3 resolutions below had been perfectly working on the same computer over Windows 10 ( also installed ). So I added them to my list.

See the resolutions and the connected interface name over :

xrandr -q

Then I added these resolutions to be available in the list.

xrandr --newmode $(cvt 1280 1024 60 | grep Mode | sed -e 's/.*"/1280x1024/')
xrandr --newmode $(cvt 1600 1200 60 | grep Mode | sed -e 's/.*"/1600x1200/')
xrandr --newmode $(cvt 1920 1080 60 | grep Mode | sed -e 's/.*"/1920x1080/')

Then I added them to the interface that I am using -- mine was DP2 , your might be VGA, DVI, HDMI, etc...

xrandr --addmode DP2 1280x1024
xrandr --addmode DP2 1600x1200
xrandr --addmode DP2 1920x1080

Then, Voila ! It works...

And, NO need to REBOOT !!!

Note: Please make sure you add WORKING or WORKABLE resolutions to the list !
