[opensuse] KDE4, dual & multiple monitor support
Does anyone have nvidia specific dual head functionality "twinview" working on KDE _4.3_? This never worked on 4.0, 4.1 or 4.2 and it's with no surprise that I find it doesn't work in 4.3 either. Is dual monitor support in KDE4 still a pipe-dream? I see lots of people on every distro asking questions but nobody supplying any answers. I can _occasionally_ get two working monitors by applying new settings on the fly with nvidia-settings utility, but after saving the config this setup *never* works once you startup a new desktop session. Manual configs have the same issue. The second screen is black... but is receiving an output signal. Can anyone offer some *informed* advice about this or should I suck it up and go back to using KDE 3.5 for the next two years? Cheers the noo, Graham P.S. separate X-screens setup doesn't work either, with or without xinerama. P.P.S No, its not my config, my config works in KDE 3.5 and other desktop systems -- “Experience is the name everyone gives to their mistakes.” ☘ Oscar Wilde -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I believe that is how I have my desktop setup. Admittedly it is not KDE 4.3, but it "just worked" when I moved from KDE 3.5.9/10 to KDE 4.2. When I get to my desktop, I can send you whatever configuration you might find helpful. I am using the "nvidia" driver, but a rather old version of it.

Works here.

I can work with you on it a bit, but I'm not an expert of Xinerama, Twinview, or KDE's support for them and how it works under the covers. I got pretty good resolving issues for a while there under KDE 3.5, but I haven't had anything about Twinview/Xinerama break since installing KDE 4.2.
P.S. separate X-screens setup doesn't work either, with or without xinerama.
I've gotten Xinerama to work. I don't think Twinview is any better for my usage; probably worse.

That doesn't mean it is not your config. "Proof" by analogy: In C, printf("%s\n", MULL) prints "(null)" when using glibc, "" which using the AIX libc, and crashes on other platforms; none of the platforms is at fault -- the code is bad even if it "works" on AIX. -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/

Not true. I have been running twinview on every version of kde4 since 4.0.4 first escaped into the wild ...;-)

I couldn't live without a dual-head display now. I even had the IT department at work install an upgraded video card and monitor on our workshop PC.

Using the nvidia proprietary driver, the following sections from xorg.conf should be a start: Section "ServerLayout" Identifier "Layout[all]" Screen "Screen[0]" 0 0 InputDevice "Keyboard[0]" "CoreKeyboard" InputDevice "Mouse[1]" "CorePointer" Option "Clone" "off" Option "Xinerama" "off" EndSection Section "Modes" Identifier "Modes[0]" ModeLine "1680x1050" 146.0 1680 1784 1960 2240 1050 1053 1059 1089 +hsync -vsync ModeLine "3360x1050" 146.2 3360 1784 1960 2240 1050 1053 1059 1089 EndSection Note: the modelines will be specific to your monitor setup. Section "Screen" Identifier "Screen[0]" Device "Device[0]" Monitor "Monitor[0]" DefaultDepth 24 Option "RenderAccel" Option "SaXDualHead" Option "TwinView" Option "SaXDualMonitorVendor" "SAM" Option "SecondMonitorHorizSync" "31-81" Option "SaXDualVSync" "50-75" Option "MetaModes" "1680x1050,1680x1050;1280x1024,1280x1024;1024x768,1024x768;800x600,800x600" Option "SaXDualOrientation" "RightOf" Option "SaXDualResolution" "1680x1050" Option "TwinViewOrientation" "RightOf" Option "SaXDualMode" "Xinerama" Option "SecondMonitorVertRefresh" "50-75" Option "SaXDualHSync" "31-81" Option "SaXDualMonitorModel" "SAMSUNG" Option "NvAGP" "3" Option "DamageEvents" "True" Option "UseEvents" "True" Option "DisableGLXRootClipping" "True" Option "AllowGLXWithComposite" "True" Option "AddARGBGLXVisuals" "True'" SubSection "Display" Depth 24 Modes "1680x1050" "1280x1024" "1024x768" "800x600" EndSubSection EndSection Note that I originally set it up with Sax2 (hence the Sax... parameter names). As I said, the same basic config file has been working since 3.5.7, with some minor tweaks for hardware upgrades along the way. I just don't let the nvidia setup utility change it when I upgrade drivers. There are instructions on the nvidia web site that I found useful for getting it going (I just don't have the link handy at the moment; if I can find it, I'll post it). -- =================================================== Rodney Baker VK5ZTV rodney.baker@iinet.net.au =================================================== -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
Boyd, Rodney, Thanks for the words of encouragement The nuclear option (rm ~/.kde4/share/config/plasma*) and a couple of manual tweaks to the metamode section proved to be successful, twinview is now apparently ok. I'll save the fight with dual X-screens for another day. I can now go back to venting my frustrations at eclipse!!
