I am running a 7770 not a 4890 as indicated in my sig. Since installing the proprietary driver using jockey, I am not longer able to see thumb nails when I hover over Icons on the Icon Only task Manager. This worked fine with the xorg drivers, and no settings have been changed. Any idea how to correct this?

Is OpenGL 2 compositing operating?

As far as I know, yes.

what version of KWin are you using? In case you have at least 4.9, please run:

qdbus org.kde.kwin /KWin supportInformation

I see the taskbar thumbs is turned off here but yet the effect is turned on, and I get no error message about it.

please try starting KWin with KWIN_DIRECT_GL=1, that is from a console:
KWIN_DIRECT_GL=1 kwin --replace &

From a console inside KDE or do I need to switch out to something like TTY1? I tried in KDE and everything flashed for a moment but no changes regarding the thumbnails.

Code: Select all

xplorer4x4@xplorer4x4-MS-7673:~$ KWIN_DIRECT_GL=1 kwin --replace &

from a console inside KDE is fine. Could you do it again and run the qdbus command again when using that version?

Sure here ya go:

Stupid question: is there an empty area that looks like the thumbnail should be in it or is there just a small popup with the caption?
Do you use thumbnails in alt+tab? Do they show up?

Oh, and in case the answer is "small popup" and "yes" - keep kwin compositing and running, then call
kquitapp plasma-desktop; sleep 5; plasma-desktop
(from konsole in KDE)

I see no reason this is a stupid question. It is just the caption. No I do not. I don;t even use ALT+TAB anyways but it shows me sliding windows. Can;t think of the proper description for it atm.

The answer has always been small pop up. I always got a text pop up but not a thumbnail(since switching to the AMD driver).

Here is the output from that command:
http://pastebin.com/aaEUKcSk

Output from compositing only added one line:
QMetaProperty::read: Unable to handle unregistered datatype 'WindowOperation' for property 'KWin::Options::operationTitlebarDblClick'

Putting the plasma-desktop to sleep worked though! I just hope this will stick after a reboot.

No. Won't stick, sorry.
Plasma doesn't notice that there's a compositor, fro vast details on the problem (originally a Qt bug) see https://git.reviewboard.kde.org/r/107983/

Odd I swore it worked last time I rebooted! Oh well thanks for the help! Is there any way to run this in a screen or something until a fix is pushed?
