I have several machines of various ages running 10.04.01 netbook Kubuntu. Until recently, all had working desktop effects using the default install settings. Two of the more recent machines could be a little slow on the display, and have had RAM upgrades which cleared the problem. The oldest, an Advent QC430, has not had a problem, despite having only the original 1GB RAM.
Today, all the machines have disabled desktop effects and compositing, pretty much simultaneously.
Attempting to re-enable effects returns a message that effects could not be enabled with the chosen (default) settings and that I should try reconfiguring or checking my X settings.
No configuration changes make any difference, the same error message is still returned .... with the notable except for changing from OpenGL to Xrender, which puts the machine in molasses mode and you cannot get out of it because attempting to reselect OpenGL fails with the error message and the system returns you to Xrender mode configuration.
2 days ago, updates included xserver-common and xserver-xorg-core. Are these a possible source of this common trans-system glitch?
