This bug report identifies a weakness in gnome-core that allows APM problems to cause the gnome panel to crash. PRE-EXISTING ISSUES: Its a known problem that the current APM code conflicts with the BIOS of some laptops. I report here that on these systems, reading /proc/apm can cause seg-faults(rh7.0) or system crashes(rh6.2). I also report that the "battery_applet" of gnome will seg-fault(rh7.0) on these systems. OBSERVED PROBLEM WITH GNOME-CORE: Specifically, under RH7.0. When new user accounts are created, and the user chooses gnome as his default session manager, the gnome panel seg-faults, restarts and seg-faults. This action continues until the user manages to kill it. ("killall -HUP panel" repeated until the respawning process is caught at the right moment.) WHY: New users must rely on the "last stop" hard coded defaults of gnome-core-x.x.x/panel/session.c to define their initial panel. On systems with /proc/apm, session.c forces the inclusion of the battery applet into the panel. APM problems, identified earlier, cause the battery applet to fault. That faults the panel, causing the observed problems. SOLVING THE PROBLEM. (soapbox alert) I really hate the fix a problem in the wrong place. Clearly APM is the root of this problem and needs to be fixed. But! where pre-existing problems are known, ignoring them looks bad. Problems with APM are gnome's problem when ever they are allowed to intrude. I hope that the maintainers of session.c will disable the "last stop" function responsible for including the battery applet in gnome panels. When the APM/bios conflict is resolved (not likely any time soon) it can be re-enabled. Glenn Beer PS. on a user by user basis. Disabling APM in the kernel allows the panel to start normally. If the user then saves his current desktop session, He won't be troubled by this again. This works even if apm is later re-enabled.
