garbled screen inside KDE
I have this kind of screen output in KDE...
 I have NVIDIA 7600gs and I tried latest 190.53 and beta 195.30 with same results. Thing that confuse me most is that I don't have these troubles when I log into Enlightenment or LXDE environment.  Anyone have the same problem or solution?  |

OK, I didn't wrote but, things are the same with composite disabled.
Maybe not the same amount but still have these glitches on screen. |

Re: garbled screen inside KDE
Looks to me like there is something wrong with your card. KDE in 2d mode also uses some xrender acceleration.

Re: garbled screen inside KDE
Well, here is what I tried...
I started Openbox as GUI (or Enlightenment or LXDE) and start glxgears and also Google earth (which I would say is pretty demanding) rotating half a globe and open browser and few other windows and I never have these noise on screen. Maybe it's the card, but I wonder... is there any Graphic card test app or Video memory test for Linux? |

Re: garbled screen inside KDE
I believe it's something regarding linux driver...
because, when I try this card in windows with latest drivers I have no troubles... I can start GoogleEarth... I can play games, lets say, FarCry in full resolution of my monitor 1680x1050 with maximum settings and have nothing like I have in Linux, specially KDE If card is defective, shouldn't I have some troubles in the Windows also...  |

Re: garbled screen inside KDE
Check the frequencies if they are ok. Enable coolbits if they aren't already and try lowering clock.

Re: garbled screen inside KDE
Coolbits enabled. I try lowering but also raising GPU/MEM freqs but no change in behavior.
I even installed gnome and compiz to try out with their composite effects and I have no glitches on the screen... I tried 180.60 driver and then I have less noise on screen than with 190.53 or beta 195.30 (but I still have it)  |

Re: garbled screen inside KDE
I think I have a similar problem: http://www.nvnews.net/vbulletin/showthread.php?t=143909
It only appears as soon as opengl is used. (KDE seems to use opengl) If I use X in failsafe xterm mode, everything works fine but as soon as I run glxinfo from this terminal, the screen is garbled. |
