Hello *,

I've updated my notebook from Kubuntu 8.04 to 9.04 last weekend. Everything works perfectly fine except for one extremely annoying bug: Every time I login, KDE deactivates the desktop effects.

I've remotely connected to my machine via SSH and checked when exactly ~/.kde/share/config/kwinrc changes and I found out that it happens during login:

I open the "System settings" => "Desktop" and toggle the check-box "Enable desktop effects", click "Apply" and the damn cool cube is there

Then I check ~/.kde/share/config/kwinrc and the section [Compositing] says "Enabled=true" (=> no file permission problem).

I logout and check the configuration file again: No change (still compositing enabled).

I login again and now [Compositing] says "Enabled=false" - and of course the cube is not there

Any idea how I can prevent this from happening? Shall I file a bug?

Btw. I'm running Kubuntu 9.04 on a Nexoc E 705 III Extreme notebook with an Nvidia GeForce 8800M GTX (at least that's what lspci says).

Best regards, Marco

P.S.: Kudos to the KDE team! KDE 4.2 is a great piece of work (by far better than 4.1 and especially 4.0) and reached the point of professional usability even with big-desktop on 2 screens (=> on my desktop machine - not my notebook).

It is possible that either:
A) Something other than KWin is reverting your choice
B) KWin is itself reverting the configuration file either due to internal blacklisting, or due to insufficient performance when it is started.

Thanks for the quick reply!

I guess, I'll ask then in the Kubuntu forum, too, but first:

Is this logged anywhere? I've checked ~/.xsession-errors as well as /var/log/kdm.log and /var/log/Xorg.0.log, but didn't see anything suspicious. Maybe I overlooked it, though...

In which log file should I look for what?

And doesn't KDE tell me about this in a dialog? When I enabled ntp on another machine and the time jumped into the future by one day, a dialog popped up telling me that desktop effects were disabled due to performance issues. The behaviour was different, though: When I tried to re-enable desktop-effects in the settings, it failed and I had to logout and re-login (I restarted X, additionally, not knowing if that was really necessary).

Best regards, Marco

...just for reference: I posted to the Kubuntu forum.

I do not believe KWin does any logging, except any you would find in ~/.xsession-errors
KWin should provide you with notification it disabled desktop effects, but sometimes these notifications are not delivered ( or you never get the chance to see them )
