Hi users and devs,
My Geforce 6200 is never worked properly in my box.
I have found there are three problem (don't know if they are related?)
* Screen corupption (see the screen cap below)
* glxinfo looks properly, but glxgears report 20 ~ 60fps and slow down the system radically.
* random lockup (recoverable with ssh and killall -9 X)
I'm not using compiz / xgl stuff.
Distro: Gentoo 2.6.18-gentoo-r6 / 2.6.20-gentoo-r8
nvidia-drivers-1.0.8776 / 9755
I've tried turn on / off FastWrite / SBA
Switch AGP rate betwen 2x / 4x.
I've also swtich between agpgart / NvAGP
But the situation does not get better.
I found one interesting thing, the corruption never appears within
the gnome-terminal window. but on the desktop / other gtk apps / OOo / Acrobat reader
And screen captures showing the problem.
Usually the screen corruption will be cleared when I switch desktop.
But appear again after a short period.
In some apps, the behavior appears more serious. (eg: OpenOffice.org or Acrobat Read)
