black screen if sna & TearFree

black screen if sna & TearFree

[Grant]

I'm using a Dell XPS 13 laptop on Gentoo and if I use:

Option "AccelMethod" "sna"
Option "TearFree" "true"

my video tearing problem disappears, but if I close my laptop lid for
a few minutes, it comes back up with a black screen, although I can
get my session back if I switch to VT1 and then back to VT7.  I can't
find anything in the logs.  I've tried xf86-video-intel-2.20.3 as well
as the latest from git.  The problem doesn't occur without the above
two directives.

Does anyone know how to diagnose or fix this?

I can prevent this if I issue 'xset -dpms' before closing the laptop
lid, but xlockmore automatically re-enables dpms unfortunately.  BTW,
this does not prevent the problem:

DPMS (Energy Star):
  Standby: 0    Suspend: 0    Off: 0
  DPMS is Enabled
  Monitor is On

It has to be this:

DPMS (Energy Star):
  Standby: 0    Suspend: 0    Off: 0
  DPMS is Disabled

I've tried different kernel versions as well as different versions of
xf86-video-intel and xorg-server with the same result.

The implication would seem to be that an action during dpms is going
wrong. Does a simple 'xset dpms force off; sleep 1; xset dpms force on'
trigger the error? If so can you please attach your Xorg.0.log and if
you could compile with --enable-debug=full and send me the log
reproducing the error that would be very helpful.

Thanks,

'xset dpms force off; sleep 1; xset dpms force on' does indeed trigger
the error.  I've attached my Xorg.0.log.old which includes the
segfault backtrace.  I'm like a newborn baby when it comes to
compiling and Gentoo doesn't have a debug USE flag for
xf86-video-intel or xorg-server so I can't help there.  Is there a
different package I should check for a debug USE flag?

P.S. Sorry for the multiple sends.

It looks like I also need to do 'xset s 0' because X also crashes if
the screensaver comes on for more than a few seconds.

Screen Saver:
  prefer blanking:  yes    allow exposures:  yes
  timeout:  0    cycle:  600

Maybe it has something to do with turning off the backlight?

In the Xorg.log, the first error appears to be a failed modeset after
resume:

[  5131.319] (II) AIGLX: Resuming AIGLX clients after VT switch
[  5131.319] (II) intel(0): switch to mode 1366x768 on crtc 3 (pipe 0)
[  5131.319] (EE) intel(0): failed to set mode: Invalid argument
[  5131.319] (WW) intel(0): failed to restore desired modes on VT switch

That is going to leave the screens blank. And the subsequent segfault
suggests that I don't have sufficient safeguards to handle that failure.
Can you please run 'addr2line -e
/usr/lib64/xorg/modules/drivers/intel_drv.so 0xb9ed7 0x68517 0x5aa2e' ?
To solve what happened to prevent the modeswitch we need to have the
dmesg, preferrably with drm.debug=6 (echo 6 >
/sys/modules/drm/parameters/debug).

Compiling a debug driver is pretty straightforward.
$ git clone git://anongit.freedesktop.org/xorg/driver/xf86-video-intel
$ cd xf86-video-intel
$ ./autogen.sh --prefix=/usr --enable-debug=full
$ make && sudo make install

This will overwrite the system driver and so not need any modification
to config files. (It is possible to install into local and change
/etc/X11/xorg.conf to load the driver from there.) So just reinstall
your distro package to revert.

I reproduced the segfault on my other (identical) laptop and got:

[ 10865.673] 3: /usr/lib64/xorg/modules/drivers/intel_drv.so
(0x7f5cf32f5000+0x39ba5) [0x7f5cf332eba5]
[ 10865.673] 4: /usr/lib64/xorg/modules/drivers/intel_drv.so
(0x7f5cf32f5000+0x47015) [0x7f5cf333c015]
[ 10865.673] 5: /usr/lib64/xorg/modules/drivers/intel_drv.so
(0x7f5cf32f5000+0x4bc29) [0x7f5cf3340c29]
[ 10865.673] 6: /usr/lib64/xorg/modules/drivers/intel_drv.so
(0x7f5cf32f5000+0x57708) [0x7f5cf334c708]

so I changed the command:

# addr2line -e /usr/lib64/xorg/modules/drivers/intel_drv.so 0x39ba5
0x47015 0x4bc29 0x57708
??:0

??:0

I've attached kern.log since the segfault.  It looks like there's some
good stuff in there.

If it's still necessary for me to do so, please tell me how to install
into a folder (/usr/local ?) that I can delete later to completely
wipe out the install.
