Need help configuring dual monitors
I just did a fresh install of Jessie (8.7.1-amd64-netinst) on a brand new HPE ProLiant ML10 Gen9. I'm still learning my way around GNU/Linux and could use some help setting up dual monitors on this workstation. I'm not entirely sure where the problem lies - both monitors are connected (via display ports) and displaying but I can't figure out how to extend the desktop instead of having the same thing on both screens. I installed Arandr which I have used successfully on another install (on an Acer laptop) but it looks like it only sees one monitor.
Is it possible I need to install non-free HP drivers or some other package in order to get the desktop extended onto both monitors? Any help or guidance would be greatly appreciated. I will gladly provide more information upon request.

Re: Need help configuring dual monitors
I fixed the image link (I think). I hope it is to your satisfaction. A meaningful error message when trying to upload an image might actually prompt people to search for the "proper" way to include an image.GarryRicketson wrote:Attachments, How to post a screen shot and use code boxesApparently the board attachment quota has been reached so I can't upload a screenshot...
Now that the screenshot dilemma is resolved, I still need to know what I'm missing to get my desktop extended...
Re: Need help configuring dual monitors
that's arandr in the screenshot.
try dragging the screen around, maybe the other screen is underneath?

Re: Need help configuring dual monitors
When I try to drag the screen it just snaps right back. I'm fairly certain that the system thinks there is just one display port available. I need to figure out why and correct it. I didn't find much enlightenment in the BIOS Configuration, only more uncertainty. Xrandr and hwinfo both seem to think only one monitor exists:debiman wrote:that's arandr in the screenshot.

It's stoopid, ugly stuff like this that sends people running back to Windoze. I may not be a fan, but it just works.

No it doesn't. That is why I don't use it, but if that is what you prefer, use it.
It gets old hearing all these windows users crying because they think Debian should be the same.

Re: Need help configuring dual monitors
Well if you don't want people to "troll" your precious thread, which is public by the way, then don't de-rail your topic with comments that invite argument. Is this the only reason you came here, to tell us how "windows ,just works" ?clarkleach wrote:

Even though it doesn't , and that Debian is "It's stoopid, ugly stuff like this ", stupid stuff like this ?
It is not the fault of Debian or Linux, that you don't know what you are doing.
Also you should learn, after making one "troll" comment, if you don' want the other troll to respond, the last thing you should do is reply to the other trolls comment.
I would not have responded , nor said any more, but after reading this I couldn't resist , " just keep your pie-hole shut "... your funny , thank you for giving me my laugh for the day.

Re: Need help configuring dual monitors
FWIW, I just booted this machine from a live Kubuntu DVD (16.04) and it came right up with the desktop extended to both monitors.
The screen positions were reversed relative to each other, however. That took a whole 20 seconds to correct.
This, it would seem, rules out any hardware or BIOS issues.
Any idea what is so different between Kubuntu and Debian/KDE?

Re: Need help configuring dual monitors
Glad you found a GNU/Linux that works for you. Subtle differences in setup can cause these differences. Packages in *buntu 16.04 are newer than Debian 8.7 due to the way the release cycles work, and can cause differences in support with some hardware. This can be an issue on Windows as well, which I'm sure you know if you've ever installed Windows and spent hours tracking down drivers. It really depends on your hardware unfortunately, regardless of OS.clarkleach wrote:FWIW, I just booted this machine from a live Kubuntu DVD (16.04) and it came right up with the desktop extended to both monitors.

Re: Need help configuring dual monitors
My remark about "stoopid and ugly" things was not meant to flame Debian specifically. It is my preferred distro, systemd notwithstanding. It was meant more as an observation of the GNU/Linux ecosystem in general. I believe (and I'm not alone) that there has been too little effort in developing and enhancing the overall UX. Also too much chaos and too little consistency. This problem I'm experiencing is just one example of relatively simple glitches that I believe should have been ironed out universally within Linux by now. If Micro$oft can get it right, surely "we" can. Dealing with Windoze drivers - well, that is a nightmare I would not wish on anyone. Generally, I've had good luck with them but when things get ugly things get really ugly Anyways...JLloyd13 wrote: Glad you found a GNU/Linux that works for you.

About finding a GNU/Linux that works for me - the jury is still out on that one. I have yet to install all the stuff I need to run and the first application I installed in Kubuntu has already presented an issue that I must deal with. Specifically, I installed Eclipse CDT (Neon) and it starts up with a blank welcome screen - an issue I thought had been resolved and which did not present itself in Debian 8.7.1 (once I installed JDK 8 so that it would run at all - something I didn't need to do in Kubuntu)... You see where I'm coming from with my frustration regarding inconsistencies? More variety isn't always better when each flavor sucks in its own particular way. In that regard the BSD development philosophy makes a lot of sense.
I would still prefer to run a "pure" Debian if I can resolve the dual monitor issue. Probably because I am most familiar with the Debian way of doing things...
Still looking for answers...

Re: Need help configuring dual monitors
You can't just say that windows work right out-of-the-box and expect to get away with it. What exactly is a clean windows installation (without drivers, firewall and a lot of configuration) capable of doing?

Re: Need help configuring dual monitors
You got me there. I will concede that setting up a new Windoze install is no picnic and their way of handling drivers makes not-so-much sense... However, since most PCs (sadly) come with Winblows pre-installed, most people never have to deal with these problems. The UX is another issue entirely and Linux, in general, has a ways to go.pkladisios wrote:You can't just say that windows work right out-of-the-box and expect to get away with it. What exactly is a clean windows installation (without drivers, firewall and a lot of configuration) capable of doing?
That being said, the question still remains - can anyone help me figure out what's broke and fix it so I can move on? I know just enough about the innards of Linux/Debian to be dangerous and not enough to know where and how to look for the information to resolve this.

Re: Need help configuring dual monitors
You should try a live configuration of your X server, using xrandr. As debiman correctly pointed out, if you have multiple monitors connected, all the monitors should be listed by simply typing:
Assuming that xrandr detects two monitors, DVI-0 and VGA-0, the following command would extend the screen from the DVI-connected monitor to the VGA-connected monitor with VGA being on the right side:
You can reverse the visual output by alternatively typing:
Keep in mind that the xrandr configuration is not permanent (hence the characterization as live configuration) and, therefore, you'll have to do additional steps like creating a bash script that runs at startup. This is just a test to see if you can actually tamper with the screens.
Code: Select all
xrandr
Code: Select all
xrandr --output VGA-0 --right-of DVI-0
Code: Select all
xrandr --output VGA-0 --left-of DVI-0

oh, where have i heard that one before...I believe (and I'm not alone) that there has been too little effort in developing and enhancing the overall UX.
but as with all FOSS projects, the solution to that is right at your fingertips.
yes, the opensource community has been waiting for you to clean things up & be consistent about it!Also too much chaos and too little consistency.
no, you're not. instead, you rant about how things should be (in your opinion) and have no resources left to solve a fairly simple problem.Still looking for answers...
