Hi,
The messages that KDE applications try to send are unreadable (maybe because it's black text on black background). For example such a message appears when KWin cannot enable some effects. I'll attach a picture too, as I cannot see how to do it directly from here.

Image from ImageShack, I know it gets deleted at some point, but not in a matter of days.

what plasma theme are you using? try oxygen

Hi, I'm generally using Atelier, but now that you suggested I tried a lot of different themes, including Oxygen, and there's no difference, I get the same appearance of the pop-up, it doesn't seem to be related to the theme, somehow.

1) try as different user

2) try with desktop effects off

Also, try removing /var/tmp/kdecache-$USER/ outside KDE.

Which colour theme do you use? (As selected in System Settings > Application Appearance > Colours)

With another user I don't have these problems, and that indicator pop-up does seem to resemble the Plasma theme.

After I changed the colour in the settings, I started having the notifications in the Atelier style, with readable colours, but after I deleted kdecache it came back to the black one in the screenshot.

What minimal set of configuration files do you think I should delete in order to fix this? I also have other problems that don't appear for the other user:
-I can't activate OpenGL compositing
-I don't see any desktop effects in the "all effects" list
-unmaximising windows will actually leave the maximised on the vertical.

you probably should do this outside of KDE - I would rename/move/erase all files in ~/.kde/share/config that are named kwin* (note: depending on the distro these files may be in ~/.kde4)

Code: Select all

 rm ~/.kde/share/config/kwin*

and if the above didn't work try resetting plasma* and this will wipe out all your plasma setting and reset them to default values, the code is written to run within KDE

Code: Select all

kquitapp plasma-desktop
 sleep 20s
 mkdir -p $HOME/plasma-config/
 mv $(kde4-config --localprefix)/share/config/plasma-desktop* $HOME/plasma-config/
 plasma-desktop &

Thank you,

I played with kwinrc and kwin --replace and it worked. I had to deleted some strange rules about video cards and OpenGL to get back the list of effects.

To get back the pop-up, I deleted some more stuff, among which the problem seemed to be some references to BeShadowed which I compiled for an older version of KDE 4.
