Package: xserver-xorg-core
Version: 2:1.16.0-2+b1
Severity: important
Dear Maintainer,
On my laptop with 2 graphics cards (integrated Intel + discrete Radeon 8770M)
X.Org
crashes in the very beginning of KDE startup. I.e I enter my login and password
in KDM
or in lightdm, the KDE splashscreen shows up, and X crashes right after showing
the
first icon on KDE splashscreen.
This is caused by a null-pointer dereference in libpciaccess0, but I'm not sure
if it's libpciaccess or X.org bug... pci_sys is NULL, does that mean
libpciaccess
failed to do something or X.org failed to correctly initialise libpciaccess?
Stack trace:
Program received signal SIGSEGV, Segmentation fault.
