I cant find anywhere in my distro other than nvidia and native display app.

I do appriciate all your attempts to help me. Its so frustrating.

I guess I could write a script like xrandr --output DVI-D-0 --mode 1920x1080 to run after login if I have to.

Or maybe check some logs but dont know which ones.

Yes my hardware supports 1080p.

I think that if you create a script you'll be ahead of this.

My suggestion would be initially to write the script and execute it and see if it's capable of persistently maintaining the display qualities you're seeking. Then after you are certain it's working, put it in your login (initialization) script - that would be .profile in your home directory for any shell with Bourne Shell conventions: sh, sh5, ksh, bash, zsh. IF you use a C shell variation (csh and tcsh are two I know of), use .cshrc instead of .profile to provide the initial shell configuration details.

bummer, But the good news is that we now know WHY the bloody thing keeps going back to 4k.

The bad news...

I have no other ideas as to how you can force it to use xorg.conf

The way I see it is, you can ether try what masinick has suggested to you (in which case, I'll turn it over to him) or what you yourself have suggested.

I can't say that your current distro will not do the same thing in terms of say for example KDE (or any other DE) but it's a very viable option for ya nevertheless.

Here's some links for ya to look at in that case;

I was hoping that we would have solved this for ya at least 5 - 10 posts ago. Shame we have not been able to actually solve your problem for ya.

The real breakthrough moments for me, were;

This told me that xorg.conf was being looked at and therefore what I was suspecting in terms of your DE changing screen res back was on the right track (and key to the whole problem your having).

I must say that, you helped me as much as I may have helped you and it therefore was a TEAM effort! And I think this is (or at least should be) what LQ is about. So thank YOU as well!

I must also say that I have enjoyed the ride with all the twists and turns along the way (I DO honestly mean that)

I wish you the best of luck which ever way ya go from here!

Hey man, thanks so much, you are a real credit to this forum and a great human being.

Taking your time to help me, try to figure out a way to fix my issues and not stopping at any hurdle.

I have decided to stick with the native resolution and use HiDpi setting which actually looks really good on the 4k screen, for the other 2 1080p screens I will maybe use xrandr to lower the DPi.

Other than that I feel 2 new 4k screens may have to be purchased.

I like linux to much to move back now.

Thanks again. Hopefully we can collaborate again some time. Ill pm you my contact details.

While I would say "I'm glad you have solved your problem", I'm glad you at least found out what was/is causing it and therefore what your options are. And in all honesty, like I said before, I had the same problem myself, we just had to figure it out! I mean, we just had to!

If you really like me, you could maybe add to my Reputation?? Just kidding! But if you want to (and/or send us a friend request) your more than welcome to!
