can I do it via byobu on the local system (so I can reatach the screen in case of crash) or should I do it via ssh from a different machine?
I really do not know how long it would take to actually hit gold here, so think I cannot keep using two systems at once for several days... any ideas? every time I enter gdb and try to attach the runnig Xorg pid, it freezes... if I try to run if with the -keeptty -dumbSched options, it tells me Xorg is already running (of course)... if I kill it, it simply respawns... the guide seems pretty useless cause if you follow the steps there, you cannot get any backtrace whatsoever. How can I ever get X to run inside gdb? (I know I could sudo /etc/init.d/gdm stop, but the only time it is mentioned there, is totally unrelated with the steps to get the backtrace) that said, I did manage to start inside gdb and pretty much as soon as I have loged in, it halted with a SIGUSR1 adn wont resume no matter what I try... I am not sure what I am doing wrong or if that could be related with the issue: (gdb) run -keeptty -dumbSched Starting program: /usr/bin/Xorg -keeptty -dumbSched [Thread debugging using libthread_db enabled] X.Org X Server 1.10.1 Release Date: 2011-04-15 X Protocol Version 11, Revision 0 Build Operating System: Linux 2.6.24-29-server i686 Ubuntu Current Operating System: Linux fpc 2.6.38-996-generic #201103251543 SMP Fri Mar 25 17:11:59 UTC 2011 i686 Kernel command line: BOOT_IMAGE=/boot/vmlinuz-2.6.38-996-generic root=UUID=4b092518-b996-429c-b41e-9bf39183163c ro quiet splash vt.handoff=7 Build Date: 19 April 2011 03:33:17PM xorg-server 2:1.10.1-1ubuntu1 (For technical support please see http://www.ubuntu.com/support) Current version of pixman: 0.20.2 Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.
