Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: Jens S. Benecke (jensb) Assigned to: Nobody/Anonymous (nobody) Summary: segfault crash with rdesk 1.4.1, 16-bit and win2k3 Initial Comment: Hello, we use rdesktop (shipped with SuSE 10.0, v1.4.1) to connect to Windows terminal servers. This is to avoid having Windows locally on each PC. However, rdesktop seems to be very unstable. The same problem is with 1.3.2. One Windows 2003 Terminal server has a particular problem: rdesktop just crashes / quits: ~> rdesktop -r sound:local -a 16 -B -k de -g 1274x970 xxx.xxx.xxx.xx WARNING: External BackingStore not available, using internal ERROR: recv: Bad address Speicherzugriffsfehler This happens often when starting a program, exactly when the application startup logo appears (e.g. FEKO). It also happens when trying to save a file in any application, when the File/save dialog appears. The problem only appears when using 16-bit color depth, which is however a requirement for many of our applications. ~> gdb /usr/X11/bin/rdesktop 15717 GNU gdb 6.3 Copyright 2004 Free Software Foundation, Inc.

I'm really quite desperate now, because the alternative would be to install Windows locally on hundreds of machines again, which we all would like to avoid. Thanks! :) ---------------------------------------------------------------------- Comment By: Jens S.
