Re: Default nice value setting
Hi, Incidentially, you may have found this bug useful once upon a time: https://bugs.maemo.org/show_bug.cgi?id=374 *grin* But, anyway, the line you want to search in that bug is setpriority() which'll allow you to override the nice value from your app. Regards, Faheem On Wed, Jun 17, 2009 at 5:28 AM, Nick Nobody m...@nikosapi.org wrote: Hi, Is there a way to specify a default nice value for an application on maemo? I noticed that if an application is launched by the menu directly from an executable (using the Exec variable in the .desktop file) it gets a nice value of -1. But, if the application is started over D-Bus (using the X-Osso-Service variable in the .desktop file) it gets a nice value of 0. The application I'm working on needs at least a nice value of -1 or else it becomes unusable. Is there a way to make this happen while still being able to start the application over D-Bus?

Can you reopen that bug Faheem linked with details about your OS version if you see it on current OS version? Oh wait, maybe just forget it, it'll be WONTFIXed anyway for any current system :-) Sadly I think that you cannot raise the priority from 0 to -1 unless being root, you can just lower it so that setpriority call may not help you. The scummvm problem in the bug was different, scummvm didn't like higher priority (or better said - system audio daemon didn't like scummvm having higher priority) so the solution was to lower the priority from -1 to 0 which worked for ordinary user.

If it is really crucial for the application to have higher priority, maybe it could be installed as setuid root. In that way, it could first set priority from 0 to -1, and then drop the privileges.

Or postinstall script could add some helper to sudoers which could raise priority when started from inside the application. I think Vagalume uses this trick. ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers

Thanks guys for all the clever solutions to the problem. @Frantisek I'm using OS2008 version 5.2008.43-7 but like you said that bug probably won't get fixed. And for applications that need to go from -1 to 0 that's very easy, it's probably not even worth fixing...
