Default Fullscreen problem.

Hi folks,

My env:
- distro: Fedora Core 6
- kernel: 2.6.19-1.2895.fc6
- driver: NVIDIA-Linux-x86-1.0-9631-pkg1.run
- card: nVidia Corporation NV28 [GeForce4 Ti 4200 AGP 8x] (rev a1)

My problem:
after a kernel update the fullscreen is shrunken. That is when i start a application in fullscreen (i.e. 'mplayer -fs', or stepmania (a game), etc) the whole screen is black and the application screen is a little central quad only 10x10cm.

Mplayer (a video player) have an option "-zoom", so i can zoom the shrunken fullscreen to proper fullscreen, but another applications does not have such a option.

Any idea, what happened? How to resolve this?
TIA
S.

If the apps and games are changing screen resolution the refresh rate can change, which then can cause display "shrinkage" shall I say.

Another thing is that if your xorg.conf has only one resolution, 1280x1024 or whatever, changing to a lower resolution puts the display in a smaller area down the bottom left. Adding modes to xorg.conf will fix that.

Hi whig,

> If the apps and games are changing screen resolution the refresh rate can change, which then can cause display "shrinkage" shall I say.

and, how to avoid this?

Ok, my modes (xorg 7.1 ):

Modes "1600x1200" "1600x1024" "1440x900" "1400x1050" "1280x1024" "1280x960" "1280x800" "1152x864" "1152x768" "1024x768" "800x600" "640x480"

but still all fullscreen applications shrink the display :-(

Any idea how to fix this issue?
TIA

Refresh rates can be specified individually for each resolution in xorg.conf, but make them all the same. I forget how this is done now, because I always keep the same resolution and have no need to go lower... eg it was "1024x768_85" for me.

The lower modes may not be enabled, even if you specify them. My laptop only likes 1680x1050 for example. See if you can get a lower mode like 1280x1024 manually by pressing ctrl-alt-plus (plus on num keypad). The X log will report whether or not specific resolutions are possible.

It actually sounds like you are using -vo x11. There is no scaler with x11. Try vo=xv in your config.
