Well the more I think about it, It is possible that ubuntu had both screens working too, but they just weren't right, just like on mint and zorin. I don't remember. that may be why I moved on from ubuntu or it may have been the unity thing. I know they work because they work perfect in windows 10 for sure. I guess I will go to my other pc and make an ubuntu usb again and use it and see what happens. Thank you for helping me. I will let you know what happens in ubutu.

Now what do I check or write down and record so any linux I install I can make work great too?
Thanks for your help.

Good things are working correctly.
With all the different problems you describe without enough info for me. Being here in Texas.

All I can figure is maybe you have been corrupt iso downloads and then installing a file corrupted install. That is my take on this thread.

Anyways. Good that you are running OK now. That is all that matters.
Happy Trailz, Rok

What do you write down? Might I suggest learn how to do a md5sum of a linux iso before running a live linux installer. It will save you from grief if you learn this. Youtube is full of md5sum tutorials and what they mean and describe why I mention this,

I have used md5sum in the past, but kind of lost the habit as it seemed it always showed the right sum. I even often wondered if the sum tool could have a malware in itself, there is so many free tools, but as you suggest I will read up on it again.

I am learning alot and am going to keep learning. I have been reading about video stuff now due to all this frustration. In the past I think I always gave up and went back to windows. So now I am reading about mesa glxinfo grep lspci x org commands et cetera. right now if I type...

Code:

egrep -i " connected|card detect|primary dev|Setting driver" /var/log/Xorg.0.log

I get...

Code:

[ 23.207] (II) intel(0): Using Kernel Mode Setting driver: i915, version 1.6.0 20150522

If you look in the screen shot I attached , you will see my additional drivers shows xorg open source driver used for AMD and also an UNknown: Unknown using microdode firmware for Intel (proprietary) I believe this may have something to do with my past problems. Mabee it's possible that other distro's need that (unknown thing) to make my system work correctly. This is just a hunch.

Anyway I want to find out exactly what is going on in this current install (working wonderful and smoothly!! seems perfect!) because it seems every other time I have tried any other distro they have never actually worked properly. That is mostly why I was jumping around. I thought if this has problems and I broke it trying to correct it, then why reinstall it if I know it isn't working properly on my system. So I might as well try another and see if it will work.

Now that my system seems to be working marvelous (except that it detects "Goldstar" 72inch when I have "LG" 42inch) I want to find out exactly what it is doing that is so correct or different than what every other distro does, so that I can install other distros and then manually set them if I have to so that they work too.

1redto,

Glad to hear that you have solved your problem.

Thanks, but it is not solved until I reinstall debian and get this working under debian as the problem in the title

instructed by "rokytnji" and after checking it with md5sum, I will make a usb and install it. I will update this thread with my progress very soon.

Update: second monitor not working. Debian GNU/Linux 8.2 (jessie) ( Radeon HD 8670 / R7 250 AND Xeon E3-1200 )

My monitors are working great in my current installation of Ubuntu / mate, aside from being detected as "Goldstar" 72inch when I have "LG" 42inch.

I am working on getting debian 8.2 iso and checking md5sum then will create the usb and install along side this ubuntu to see if my original problem can be corrected.

ok I got debian-live-8.2.0-amd64-mate-desktop.iso from http://cdimage.debian.org/debian-cd/...64/iso-hybrid/

here is the md5sum listed at http://cdimage.debian.org/debian-cd/...hybrid/MD5SUMS ...

981a8502d50df86b9cda41e54071e4fc debian-live-8.2.0-amd64-mate-desktop.iso

Code:

pawn57@pawn57-Inspiron-660:~/Desktop$ md5sum debian-live-8.2.0-amd64-mate-desktop.iso

981a8502d50df86b9cda41e54071e4fc  debian-live-8.2.0-amd64-mate-desktop.iso

981a8502d50df86b9cda41e54071e4fc (ran md5sum see above code)
981a8502d50df86b9cda41e54071e4fc (copied from site, link above)

Looks like a good match!

Now I will make the live USB

There it is (makeing of the live USB)...

Code:

root@pawn57-Inspiron-660:/home/pawn57/Desktop# sudo dd if=/home/pawn57/Desktop/debian-live-8.2.0-amd64-mate-desktop.iso of=/dev/sdb oflag=direct bs=1048576

992+0 records in

992+0 records out

1040187392 bytes (1.0 GB) copied, 43.4175 s, 24.0 MB/s

Now I will boot the live USB and install Debian.

OK, Bad News so far....

(This post is from my spare pc) I booted from the live usb and installed debian (I had to disable secure boot to get the live debian usb to boot) I resized the biggest partition to make room and installed on the free space. as per on screen instructions That detected the ubuntu installation, and I did everything like it suggested. after install upon rebooting my pc says no boot device available. I can't get in on ubuntu/mate or debian. the pc is bricked. (thus why I'm posting from my spare pc) soooo what I have decide to to try is ... I will try and reboot from the debian live usb, do a clean install of debian only, then install ubuntu/mate again and see how that goes...

I will report back with my progress soon.

my bad. Disregard my last post.. I set my pc to boot legacy mode in bios and now I got menu for ubuntu/mate and debian!!!!!!!!! I just booted ubuntu, both screens still work perfect!! now I will reboot and select debian (will be my first boot into it) be back soon i hope...

As explained earlier. No surprise that a Debian install is not running a proprietary video driver blob in it's iso.

No matter either if Mate is in Debian. So expect a repeat of earlier results.
Without certain firmware and drivers. I expect failure in yor next post.

rokytnji

Thanks. The first two links don't seem to help me.
