Public bug reported:
Using Xubuntu 16.04, including light-locker, whenever the screen has
been locked the X server will SIGABRT crash as soon as the user has
entered their credentials. This happens 100% of the time.
The only related information I can find is a Debian bug report:
https://bugs.deb
The NULL device bubbles up from
xserver-xorg-input-
libinput-0.18.0/src/xf86libinput.c::xf86libinput_pre_init()
where it does
is_subdevice = xf86libinput_is_subdevice(pInfo);
if (!is_subdevice) {
...
} else {
InputInfoPtr parent;
struct xf86libinput *parent_dri
The log file shows the input device(s) being removed upon system idle
and the attempt to re-attach it failing.

That bug affects the "Fix released" status of this bug since this work-

Discussion with Adam Conrad on IRC #ubuntu-devel:
A recent change to the nvidia DKMS drivers package has broken another
package such that it won't conceivably ever work again. What's the procedure in
such cases?
TJ-: That might need to be slightly less vague.
infinity: bug #103991
A ray of hope for the alternative. After fixing a bug in the nvidiabl
kernel module[1] I can use the standard OS brightness controls to
control the backlight. More work needs to be done on that, and it needs
to be brought into Ubuntu, but it is the proper solution and it does
work for many devices.
I've been experiencing this recently with the Bluetooth mouse. It occurs
after multiple suspend/resume cycles - I'd guess 4 or 5 cycles before it
hits. The mouse associates but the cursor is no longer controlled, and

Having just patched glib to fix bug #290935 "dual screen all panels end
up on one screen at startup" I'm using dual screens again and hit this
bug whilst using compiz cube and nvidia drivers.

I neglected to install the libgtk ebug symbols for the previous back-
trace. Here's a summary of the key parts that I'm focusing on:
#19 0x7fd66d49a588 in gdk_window_x11_set_cursor (window=0x148f960,

#20 0x7fd66d
Looking at the libx11-dev package source code I see that the 'Display'
value is optimized out into a register variable, which is a pain since
that is likely key to the bug and doesn't show up in gdb output.
libx11/src/DefCursor.c:
int
XDefineCursor (
register Display *dpy,
Window w,
C
I believe I've managed to identify the issue here. It is dependent on my
having correctly navigated the register variable identification. Gdb is
supposed to report which register the variable is stored in using "info
address dpy" but this reports "Symbol "dpy" is a variable with multiple
locations"
