I'm sorry for this big delay, but I've finally taken the time to test
this out.

I can confirm that the visual glitches and crashes are still present in
the latest version of the package, 2:1.19.0-2.

Also, when using the above-mentioned technique for forcing the driver to
"intel" (I've confirmed that it loaded by looking at
~/.local/share/xorg/Xorg.log.0), I don't see visual flashes anymore.

Bug#845981: xserver-xorg: Desktop freezes

2016-11-27 Thread Michael Rasmussen 
Package: xserver-xorg
Version: 1:7.7+18
Severity: important

Dear Maintainer,

After latest xserver-xorg upgrade the desktop constantly freezes. It was 
working with 1:7.7+17. Symptom seems to be related to the lock file 
(/tmp/.X0-lock) which in some way confuses the X server so it thinks another x 
server is already running. I have downgraded to the version in stretch so the 
log file below is replaced with Xorg.0.log provided by 1:7.7+18.

My question is, why is __USE_POSIX not defined?

Not sure if this would be the xserver's fault for not defining _XOPEN_SOURCE or
__need_sigset_t, or virtualbox. I'm thinking the latter as in a simple test
case, including signal.h without doing anything else gives me sigset_t.

Cheers,
Emilio

Bug#830523: Easy workaround found

2016-11-27 Thread Shai Berger 
Hello,

I was able to find an easy workaround for this problem:

0) Make sure xserver-xorg-input-evdev (or some other input driver to handle 
the keyboard and mouse) is installed. If your system is not brand-new, they 
are probably installed anyway

1) Disable the configuration that causes libinput to be used:

sudo mv /usr/share/X11/xorg.conf.d/40-libinput.conf{,.disabled}

2) Restart X

Maintainers: Do you know if this has been reported upstream? Conversely, do 
you know of a reason to suspect that this is a Debian-only problem?

Thanks for your good work,

Shai.
