 |
|
I am experiencing a blurring effect on my desktop. it fades in and out, affecting different parts of the screen at random intervals. this is a brand new nvidia card and I am using the nvidia driver. this does not happen during the boot process, nor during the kdm login screen. this only happens after the full kde environment is loaded. disabling desktop effects has no impact. how do I troubleshoot this?

1/ check xorg.log for error and warning
2/ switch to another driver: nouveau or vesa and see if problem persist, could also run any livecd/dvd with a DE in it to see result. |

| thank you. the fix for me was to use nvidia-settings to lower my opengl settings. I think I was cooking the card. |

Turning off OpenGL compositing would probably fix it.
I remember having a similar problem on an nvidia card and compiz... when I dumped my GeForce MX for a Radeon 9250 I didn't think they'd still have bad output a decade later  |
