Public bug reported:
With the update to the 2.6.27 kernel yesterday, screen refreshes using
the Nvidia 177 driver, (GeForce 8400 on a Dell M1530) are often
incomplete - i.e. when changing webpages inside Firefox, and/or pretty
much any other multi-page window-based app, when navigating to a new
page, will at best get only the line(s) beneath the mouse updated before
having to click inside the window, at which point usually the rest of
the page will refresh, though sometimes have to click multiple times
within.
Also seems to affect screen resolution changes - i.e. still can't get
the computer to hold @ 1280x800, 3D accelerated across sessions, (keeps
falling back to 800x600 at the login screen). Smaller resolution
changes work ok, but with a noticeable lag/refresh, (i.e. 800x600 to
1024x768 & 1024x768 to 1280x800) but larger resolution jumps, (i.e.
800x600 to 1280x800 directly) don't quite, showing only the 800x600
portion of the screen in the upper left, but @ 1280x800 resolution, with
the rest of the screen being black. The menu bars, etc in the black
area do indeed function if you know where they are, but do not restore
display of the rest of the screen.
Will say that I'm not sure if this is a newly-caused bug directly from
yesterday's 2.6.27 release, or simply as a function of the forced
upgrade from nvidia-glx-173, which I was using up through the 2.6.26
kernel, (-177 wasn't working quite right, but when trying to revert back
to -173, an error popped up saying something about no DKMS for -173 with
the 2.6.27 kernel).
