Bug#398067: xserver-xorg-video-vesa segfaults with Cirrus Logic GD 7543 [Viking] since upgrade to X.org 7.1
Subject: xserver-xorg-video-vesa segfaults with Cirrus Logic GD 7543 [Viking] since upgrade to X.org 7.1
Package: xserver-xorg-video-vesa
Version: 1:1.2.1-3
Severity: important
Since upgrading xserver-xorg from 1:7.0.22 -> 1:7.1.0-5 and
xserver-xorg-video-vesa from 1:1.0.1.3-2 to 1:1.2.1-3 in testing, X.org
segfaults on my testing machine, with the previously working config file
as well as with a manually adapted one. Using it with startx and the
following configuration (my original one from 7.0, just with three
modules not supported by the graphics card commented out):

-end---------------------------------------------------------------------------
It even still segfaults if I comment out all "Load" lines in the
"Module" section. Even the memory addresses seem to be the same.
BTW: I haven't used the Cirrus driver, since I experience similar
effects like the ones described in #366513. If I just change the
"Driver" line to "cirrus" instead of "vesa", I get the following error:
-------------------------------------------------------------------------------
(EE) No devices detected.
Fatal server error:
no screens found
-end---------------------------------------------------------------------------
Using the vga driver and setting the DefaultDepth to 8, it works. Well,
as far as you can work with a 52x12 terminal even with font set to
fixed. But setting the DefaultDepth down to 8 with vesa driver doesn't
help. It still segfaults.
I also tried to remove as much as possible from the .xinitrc, leaving
only an xterm to start. Didn't help either, unfortunately.

BTW: I can't understand the "Can't find file "de_CH" for symbols
include" error message, since /etc/X11/xkb/symbols/de_CH clearly exists
and seems to have useful content.
And how can the line
xkb_symbols { include "pc(pc105)+de_CH(nodeadkeys)+ctrl(nocaps$
happen when I configured a 102 keys keyboard? (OTOH xkbcomp errors
shouldn't be the ones which cause X.org to segfault. Will report them
with more detailed information as soon as I got X.org working again.)
