#6 0x00007fd010115ff7 in TaskManager::VirtualDesktopInfo::XWindowPrivate::requestActivate (this=<optimized out>, desktop=...) at /usr/src/debug/plasma5-workspace-5.19.5-3.1.x86_64/libtaskmanager/virtualdesktopinfo.cpp:172 #7 0x00007fd01016b7f6 in SwitchDesktop::performNextAction (this=0x56173c914ae0) at /usr/include/qt5/QtCore/qlist.h:570 #8 0x00007fd0105e0ec6 in ContainmentInterface::wheelEvent (this=0x56173c662a80, event=0x7ffe86a0b3f0) at /usr/src/debug/plasma-framework-5.74.0-1.1.x86_64 Which tool bar? Were you rolling your mouse wheel over the pager or the desktop? Opening the tool/task bar at bottom of the screen. Using Yast to install missing libraries. Some applications would not open from the menus, using konsole showed libraries missing. Scrolling mouse wheel on screen background also crashes. Virtual desktop widget is not showing on the taskbar. Same issue happens if I use NoMachine to have desktop shown on remote machine. PC has NVidia GT1030 card and using NVidia drivers - work fine on 15.1 - dual boot machine. Thanks for the info. >Virtual desktop widget is not showing on the taskbar.
That says alot. We think has no virtual desktops
```
void SwitchDesktop::performNextAction() calls
m_virtualDesktopInfo->requestActivate(desktopIds.at(nextDesktopIndex));
```
is run but desktopIds will be empty, so this array access is out of bounds.
I'll add a guard. It'll fix the crash, but that doesn't explain the broken setup.
