Low resolution: 800x600 by default #211

Closed derkling closed 11 years ago

derkling commented 12 years ago

Hi all!

Optirun is working find on my Dell XPS15z, I've just one small issue related to resolution. If a run:

optirun nvidia-settings -c :8

I could verify that the only one supported resolution for monitor DFP-0 is 800x600. No other resolutions, even if this laptop supports up to 1920x1080.

The xorg.conf.nvidia configuration file is the default one which I got with Ubuntu 12.04:

Section "ServerLayout"
    Identifier "Layout0"
    Option "AutoAddDevices" "false"
EndSection

Section "Device"
    Identifier "Device1"
    Driver "nvidia"
    VendorName "NVIDIA Corporation"
    Option "NoLogo" "true"
    Option "UseEDID" "false"
    Option "ConnectedMonitor" "DFP"
EndSection

How I could get a bigger resolution? Thanks, Patrick

Are you currently running in 800x600 or is it only the nVidia Settings Panel which is showing that ? In the second case, you have to know that this panel can't set anything for display, as it doesn't handle the screen.

I use Bublebee to stat X-Plane... and it start at 800x600... it is not possible to switch to an higher resolution when the program is running without corrupting "the rendering". Thus I suppose that if the X server is able to start using an higher resolution everything should be fine. Isn't that possible? Thanks.

ArchangeGabriel commented 12 years ago

You may specify a resolution in you xorg.conf.nvidia. I dunno remember however how to set it correctly. But I think this information could be found elsewhere.

If you still need it, you may take a look at this : https://github.com/Bumblebee-Project/Bumblebee-old/issues/67#issuecomment-1917728

Already tested this solution, unfortunately without success... In my case I've configured just a couple of modelines based on the output of "xrandr --verbose" on my laptop, but still the xorg server discard the modeline I defined and use the default one.

That's an example of the xorg I've tested:

The issue seem related to modelines specifications... but as I told before these comes from xrandr.

That's normal, modes are firstly grabbed from this line: Modes "1280x1024" "1024x768"

Also, you should use modes supported by your monitor, which is probably not the case of all the 4:3 format resolutions you gave. Could you paste the xrandr --verbose output ?

That's quite similar to one I've already tested. Anyway, by just adding an "Identifier" string into "Monitor" section, and referring this identifier as "Monitor" within "Screen" section, still I've not success. In this case the problem is related to the "ConnectedMonitor" option, CRT-0 seem to be not valid for my system, this is the error reported into Xorg.8.log:

Hum indeed sorry for CRT instead of DFP, the file was based on mine. Dunno why it can't find a valid modes, could you try adding some modes, like 1440x900 ?

Whatever mode I add, selecting among the modelines defined in Monitor section, the result is always the same: all modes are considered not valid:

The problem seem to be related to the definition of modelines in monitor section, for same reason these definitions are ignored or not seen by xorg... Maybe there is a specific syntax to associate the a certain Monitor section (e.g. Monitor0) to a specific display (e.g. DFP-0)?

Are you still facing this issue ?

bosim commented 11 years ago

I am facing this issue also.. all other opengl apps works fine in higher resolutions but not X-Plane.. If i open optirun nvidia-settings -c :8 it shows 800x600 as well.

I've solved only recently basically by:

  1. using the xorg-edgers PPA, to get the latest and greatest XOrg and drivers for Ubuntu: http://www.ubuntuupdates.org/ppa/xorg-edgers
  2. using primusrun, instead of optirun, to start X-Plane: https://github.com/amonakov/primus

Primusrun provides to me not only window scalability, i.e. it is possible to start X-Plane at 800x600 and than resize the window by simply dragging it, but it also provides better "performances" since it loads less the CPU to "interact" with the external GPU.

Hope this could help you to take off more confortably! Ciao Patrick
