Video Card / screen configuration


#1

@Thanatermesis

I just bought a new 32 inch Viewsonic curved screen on wich I run elive at 2560 X 1440 (100% of the tim… I installed a 2nd computer to my wife, no need to run her Windows in a VM, on Ubuntu !)

My challenge for you, if it’s simple for you to fix it, is the screen configuration tool

I can’t use my 2nd monitors (whatever the size)

The screen configuration tool you created worked well for :

  • my 2 HP 22er 21 inche monitor
  • one monitor
  • my 32 inch monitor alone

but if I want the 32 inch new curved monitor, I see this

I can’t configure both monitors, I can’t change screen resolution and so on…

If I recall correctly, arandr can set up the screen resolution and orientation on the fly. It is a GUI tool built for xrandr, and there are examples for xrandr on the web, the Thinkwiki pages come to mind. I have gone back to one screen, but there is a spare flat screen, ready to get back to work. One can use either to configure the screens; once that step is done the screen setup in e’s control/settings panel can be used.

Looks like a small and simple bug to fix in the elive tool, there’s 2 things I need to know:

  • does ‘arandr’ tool as @she_dyed suggests make it working correctly ? (which is also used by the Elive configurator)
  • will need the result of your command “xrandr -q” from that computer with that screen connected (just paste it here in a code block)

This is when I connect only the new 32 in alone on the pc ( working fine)

DO you need the same command results , when the 2 screens are connected and only the 22 inch works ?

Here is the xrandr reference on the wiki for Thinkpad folks

http://www.thinkwiki.org/wiki/Xorg_RandR_1.2

There are plenty of examples there; not all your ports should say ‘disconnected’. Your xrandr -q will be helpful, and so will .xsession-errors in case VGA switches off. (.xsession-errors can be put on a pastebin to keep this thread compact) On a Thinkpad there is a BIOS setting to keep the main screen on regardless of external connections (old models did not have HDMI but only had an extra VGA-out as a secondary for projectors)

Well, first of all, in your screenshot there was a wrong result for the resolutions of VGA1, now I updated the tool and it should show “unknown” instead, and this should be correct this way, please confirm and specially that the tool continues to work:

  • apui elive-tools

But then, there’s a different problem that I don’t quite understand, you said that you want to use both screens in your desktop but it doesn’t works, but, the tool shows both screens so it detects it (almost) correctly and apparently you are configuring them correctly

So first of all, will be needed to know if you can make them working with the tool “arandr” alone, so configuring them with only that tool launched alone, makes both displays to work / appear?
