[SOLVED] NVidia GPU scaling

hi,
maybe i posting into wrong forum but here is my problem.
Coz in new nvidia drivers is no option to set GPU scaling i have few problems in some games
where i cannot set another resolution.
Game running centered on my LCD which sometimes is not very useful.

Re: [SOLVED] NVidia GPU scaling

hi, I found solution for this.
I must configure Screen section in 20-nvidia.conf
and write some Metamodes.

Section "Screen"
     Identifier "Screen0"
     Device    "Device0"
     DefaultDepth 24
     Option    "Metamodes" "DFP-0: nvidia-auto-select; nvidia-auto-select {ViewPortIn=800x600}; nvidia-auto-select {ViewPortIn=640x480}"
EndSection

etc. etc
mark as solved.

Re: [SOLVED] NVidia GPU scaling

From the release highlights:

- Removed Flat Panel Scaling configurability in nvidia-settings. Any desired scaling can be configured through the new "ViewPortIn" and "ViewPortOut" MetaMode attributes.

- Extended the MetaMode X configuration option syntax with the following new attributes:

"Rotation" : specifies the display device's rotation
"Reflection" : specifies the display device's reflection
"Transform" : specifies a 3x3 transformation matrix to be
applied to the display device
"ViewPortOut" : specifies the region of the mode in which to
display pixels
"ViewPortIn" : specifies the size of the region in the X screen
to display in the ViewPortOut

For example, "DFP-0: nvidia-auto-select { Rotation=left }".
See "Configuring Multiple Display Devices on One X Screen" in the
README for details.

IIRC they intend to bring this functionality back to nvidia-settings for the new "ViewPortIn" and "ViewPortOut" context. In the meantime you have to specify your MetaModes in your xorg.conf file.
