Two times Dual screen, not everything ok.

Hi all !

I’m [Moviuro], and I just switched from mandriva to OpenSUSE 11.4. I have got a Acer 8942G laptop (Intel Core i3), using it for LaTeX edition, Math (though i miss sagemath), virtualisation, SSH server, a bit of gaming platform, OCaml programming…
I have got OpenSUSE 11.4, Kde 4.6.00 (i’d gladly upgrade to 4.6.5 but can’t find how !!)

At home and at school, I have got a dual screen display : Laptop is 1920x1080 and second screen is 1280x1024. And as usual, with KDE, the second monitor i got home is not recognized as being capable of 1280x1024 but only 1024x768, which is hurting my poor little eyes ! (LOL). I’d like to :

  • have my second monitor display 1280x1024 when plugged
  • have only my laptop screen display something when no other display is found (with mandriva, my resolution was the good one, but X went crazy if it didn’t find the second display…)

That’s it !
Thanks to the one who will help :slight_smile:

PS: OpenSUSE is great :slight_smile:

I haven’t tried it on a laptop with a second screen plugged in, but Ati’s Catalyst Control Center which should appear under System > Configuration in Kde after installing the proprietary Ati driver works well enough for configuring multiple displays

You don’t mention whether you’ve installed the Ati driver or not, if you haven’t that might be a good place to start

This might be a silly question: it it’s an Intel i3 laptop, why does it have an ATI Radeon driver? The Intel video built into the i3 cpu is well capable of driving a dual display…

SO, my problem has been solved : I installed fglrx and setup the dual screen, everything’s fine now :slight_smile:

Still, when booting without the second screen (which happens in the bus/train), there are some unusable screen place, because of display errors. But not so awfull like in Mandriva :slight_smile:

BTW, installing fglrx reduced by 15°C my proc temperature !! It is the coolest temperature (< 50°C) i ever had with a linux distro !!! I’ll stick with the gecko for a while, I assume :smiley:

Given that installing the Ati driver appeared to have fixed the OP’s issue it probably didn’t have a radeon driver, but if you look at this line from his lspci output:

01:00.0 VGA compatible controller: ATI Technologies Inc Broadway PRO [Mobility Radeon HD 5800 Series]

As shown there, it does have a radeon graphics card
