we need more info and we need to know whether only opensuse is affected. *** Bug 281715 has been marked as a duplicate of this bug. *** What info? I cannot test other distros. From the dupe ("like opera and FBReader remain visible") i'd say it /could/[1] be related to the widget style - try replacing oxygen with eg. plastique or cleanlooks
[1] could be a Qt related bug either
Tried cleanlooks and even different plasma and windeco styles, same result, firefox et al stay visible everything else becomes black. Qt is 4.7.4 btw Xorg 7.6 Kernel 2.6.37 and also tried 3.0.3. changing the widget style, or other styles or themes, doesn't help. couldn't find any one effect responsible, and changing rendering or OpenGL options doesn't help either. turning off desktop effects globally does. 2nd shot: graphicssystem try: random_qt_app -graphicssystem native & random_qt_app -graphicssystem raster & random_qt_app -graphicssystem opengl & does any of it "work"? this looks very much like a non-kwin issue. Please report to openSUSE at it seems that Qt is broken. If some windows work correctly with effects enabled it cannot be a KWin issue. Setting to invalid unless new evidence emerges. I have to confirm this bug. Graphiccard is: NVIDIA Quadro NVS 110M/GeForce Go 7300 Driver: NVIDIA-Linux-x86-280.13 KDE 4.7.1 is installed from: http://download.opensuse.org/repositories/KDE:/Distro:/Factory/openSUSE_11.4/ But inspite of other reports here in my case Firefox or/and Chromebrowser will crash when I enable desktop effects. These applications will not remain visible and operable. Disabling desktop effects again shows only KDE-applications like dolphin or kontact having survived. Created attachment 63543 [details]
.xsession-errors
my .xsession-errors file with desktop effects enabled directly at startup
only the firefox window shows and when I hit ALT+TAB, I see the normal switcher tiling the windows in a 4x4 fashion - 3 windows are open but I only see the firefox window thumbnail
turning off desktop effects shows all 3 windows as normally
one side-effect though: whenever I turn off desktop effects, plasma-netbook uses the whole CPU and its memory usage grows (I eventually killed it consuming 700MB and restarted afterwards) - this part is not in the file anymore though...
*** Bug 281735 has been marked as a duplicate of this bug. *** Here is the openSUSE bug report: https://bugzilla.novell.com/show_bug.cgi?id=717127 I can confirm that this seems to be Qt/openSUSE related. In openSUSE 11.4 I switched to a separate Qt repository: http://download.opensuse.org/repositories/KDE:/Qt48/openSUSE_11.4/ All is working fine after that. Changing resolution. Opensuse added this patch to the libqt4 package https://build.opensuse.org/package/view_file?file=plastik-default.diff&package=libqt4&project=KDE%3AQt I have the same issue. Addionally, when I create a new user and try to login, the following error message is displayed: (translated from german) "It is not possible to save the bookmarks in /home/jjj/.local/share//user-places.xbell. The error message is: not enough rights in target directory. The reason should be corrected as fast as possible. Possibly there is not enough disk space." There is enough disk space and the user has the needed rights. *** Bug 281748 has been marked as a duplicate of this bug. *** |
