[Intel-gfx] machine lockup if startup xrandr and cmdline video= and display connection is DisplayPort

Thu Sep 10 16:26:32 PDT 2015

If on one multiboot machine:
video=1440x900 at 60 on kernel cmdline
and in startup script
xrandr --dpi 108 --output DP1 --mode 1680x1050 # intel digital
and
default/init level = multi-user.target
and
connection between PC and display is standard DisplayPort cable
and
openSUSE 13.2 i586
then startx blips the screen, then blips it again leaving a text cursor at 0,0,
keyboard fails to respond to anything, and no mouse pointer appears. Hard reset
or power cycle is required for anything more to happen.

openSUSE 13.2 booted without 1440x900 at 60 on kernel cmdline, before upgrading from
standard repos to openSUSE buildservice X11:XOrg repos:

Note the lockup in above case occurs after startx exits and writes various exit messages
on a normal looking vtty screen.

Neither does the lockup occur in the 13.2 installation if the xrandr script has

	s/DP1/VGA1/

and the machine booted after the cable is changed from DisplayPort to standard
15 pin VGA.

In amd64 Debian Jessie (kernel 3.16, server 1.16.4), lockup on exit does not occur,
but there is a startx exit oops/Call Trace preceding the line "(EE) Server terminated
successfully (0). Closing Log file." that does not show up in .xsession-errors or
in Xorg.0.log, starting with a WARNING about check_crtc_state pipe state doesn't match.

Is lockup using DisplayPort cable a known problem? Kernel? Driver? Xorg? Other?
