QNativeImage: Unable to attach to shared memory segment on KDE QT application

[baskar007]

Hi All,

Just 1 week before I updated my 14.04 kubuntu to 15.10 (no pure update, clean install)

Everything looks/works good.

It seems like I am facing QT related bug in app KDE+QT based apps.

I am getting following error & grey screen when opening apps like Klog, qBittorrent, kdialog etc...

QNativeImage: Unable to attach to shared memory segment.  
X Error: BadDrawable (invalid Pixmap or Window parameter) 9
  Major opcode: 62 (X_CopyArea)
  Resource id:  0x0

Hi ,

Finally I can fix this issue by disabling MITSHM lib.

This can be done by adding following line to ~/.profile file. (ie: system env var)

QT_X11_NO_MITSHM=1


Thanks.
