Bug#444190: OpenGL screensaver malfunctions from upgrade

[David <david.maillists@gmail.com>]

Do you know this proverb "the best way to find something is to look for another thing"? :-) Today it happened.

I wanted to enable composition, so I added to /etc/X11/xorg.conf:

Section "Extensions"
        Option "Composite" "enable"
EndSection

and

Option "AccelMethod" "XAA"
Option "XAANoOffscreenPixmaps" "true"

Compiz did not work, but the KDE translucencies did work.

Finally, I deactivated the composition effect in KDE because switching from one desktop to another one was taking at least 5 seconds (is it normal with this old card, or shall I submit another bug?).

After deactivating the composition effects, I saw many improvements, though (the days before I was working without composition as well), so I think they just came from the modifications I made to /etc/X11/xorg.conf:

* I was allowed to select in KDE the refresh rate of 75 Hz. 
* Working with KDE was faster in general.
* The problem this bug is about was fixed.

Note, however, that this bug used not to exist *without enabling composition in /etc/X11/xorg.conf *, so I do not know if the bug can be closed yet. At least, you should configure the package to do these modifications to /etc/X11/xorg.conf before closing the bug.

Please, answer as well whether taking so long for switching from one desktop to another in KDE with composition enabled is a bug or is normal for this card.

Thank you,

Unless I am mistaken, we haven't seen your config and log yet. Could
your xorg.conf and Xorg.0.log from 6.7.197 ?

Thanks,
