Bug Description

System: kubuntu natty 11.04, kde-4.7, all latest updates applied

This began yesterday (03 Aug 2011) after the kernel/nvidia updates were applied. There are two problems:

1. The fonts have become so light, that the screen is unreadable. The problem appears to be that the characters are being rendered too thin. I have to set the fonts to bold to make the screen useable at all. I have tried changing font settings in systemsettings > application appearance > fonts, both size and font style. I have also tried changing fonts -- the fonts do change, but the rendering problem remains. I have also tried forcing the dpi setting, does not solve the problem. The problem also exists in gtk applications like firefox, and changing the settings in systemsettings does not fix it.

2. The fonts shrink in size. All steps mentioned in (1) tried.

Restarting X server, rebooting, etc, don't solve the problem.

Apport done.

Screenshot attached. They don't look so bad in the screenshots, but when looking at the screen, especially black text against a light background, the text is nearly impossible to read. It is as though the width of the black pixels has been reduced.

Further experiments:

Tried booting with older kernel and nouveau driver -- same problem.
Tried unloading nvidia-current module and loading nouveau module -- same problem (I did not remove anything from initramfs).

Tried booting a backup of the system made on 7/30/2011 - works properly.
