Are you guys able to reproduce the xrdb crash constantly? Do you have a '/etc/X11/Xsession.d/30xorg-common_xresources' file?

[Ken Phillis Jr (kphillisjr)]

Timo, yes i have that file, i hadn't rebooted yet, i'll try rebooting probobly tommorow... and i think it might be constant.

[Ken Phillis Jr (kphillisjr)]

fresh reboot and i got yet another crash of xrdb, and i am also attaching the dump that it generated... to be precise the file, /var/crash/_usr_bin_xrdb.1001.crash

[Timo Aaltonen (tjaalton)]

Ok, thanks. Do you get the crash if you move '/etc/X11/Xsession.d/30xorg-common_xresources' to another place? You don't need to reboot, logout/login should do fine.

it seems that for some reason xrdb crashes if -nocpp is used for xrdb.

I can't reproduce it but from a strings CoreDump
...
-DEXT_SHAPE -DSCREEN_NUM=0 -DWIDTH=1024 -DHEIGHT=768
...

vs killing -4 a working xrdb
...
-DSCREEN_NUM=0 -DWIDTH=1152 -DHEIGHT=864 -DX_RESOLUTION=4299
...

It looks like screen->mwidth is not set by Xorg or libxcb; cf. xrdb.c:DoScreenDefines()

What does xdyinfo return?

[Ken Phillis Jr (kphillisjr)]

actually, this is a fairly similar but to what happened with QT-X11-Free, so I'll go ahead and paste the results of mine... i actually have a TV as one of my monitors and i didn't bother to fix my xorg because i don't know the mm size of my screen...

xdpyinfo | grep -a2 dimen

screen #0:
  dimensions: 1280x1024 pixels (370x280 millimeters)
  resolution: 88x93 dots per inch
  depths (7): 24, 1, 4, 8, 15, 16, 32
--

screen #1:
  dimensions: 800x600 pixels (0x0 millimeters)
  resolution: -2147483648x-2147483648 dots per inch
  depths (7): 24, 1, 4, 8, 15, 16, 32

i can reproduce this almost at will.
this machine can become a nuclear penguin as it is of low importance.
i'll be around on irc.freenode.net in #ubuntu-bugs.

[DarkMageZ (darkmagez)]

sorry, i forgot about comment 8 when i read this 8 hours ago. yes moving that file seems to resolve the issue.

[DarkMageZ (darkmagez)]

i take back my last comment... it has no/unmeasurable effect. the "almost at will" part took effect while i was testing.

i've got a THEORY of replication, and it is probably only one of the ways to do it.

set xorg.conf up with a bunch of resolutions. gdm will use the preferred one.

set desktop to a lower resolution.

open gnome font properties and click details

(repeat till replicate)

you will notice that the font sizes in gdm for your logon details vary from restart to restart.

Crashing on startup after Gutsy install.

[Timo Aaltonen (tjaalton)]

pretty sure this is fixed by now. If it still happens in lucid or newer, please open a new bug.
