ubuntu下jupiter报错问题

 由于ubuntu的电源管理有问题，导致笔记本风扇老转，又吵又耗电。搜了一通，发现安装jupiter可以解决。

我的系统是12.04，jupiter是0.1.9，不过有点小小的问题：

01	~$ jupiter

02	Exception in thread Thread-4:

03	Traceback (most recent call last):

04	File "/usr/lib/python2.7/threading.py", line 551, in __bootstrap_inner

05	self.run()

06	File "/usr/lib/python2.7/threading.py", line 504, in run

07	self.__target(*self.__args, **self.__kwargs)

08	File "/usr/bin/jupiter", line 414, in update_screen_resolutions

09	res = self.jupiter.get_available_resolutions(display)

10	File "/usr/bin/jupiter", line 181, in get_available_resolutions

11	return self.get_device('/available_resolutions_' + args,'resolutions','modes ' + args).split(' ')

12	AttributeError: 'bool' object has no attribute 'split'

14	Exception in thread Thread-5:

15	Traceback (most recent call last):

16	File "/usr/lib/python2.7/threading.py", line 551, in __bootstrap_inner

20	File "/usr/bin/jupiter", line 380, in update_screen_orientations

21	rotation = self.jupiter.current_rotation(display)

22	File "/usr/bin/jupiter", line 166, in current_rotation

23	return self.get_device('/rotation_saved_'+args, 'rotate', ['normal',args]).split(' ')[0]

24	AttributeError: 'bool' object has no attribute 'split'

再搜了一通误解过，只好调试了一通，发现176行的函数def get_displays(self)返回的值有问题，包含空的元素，然后

update_screen_resolutions、get_available_resolutions、current_rotation等函数就会出错

就把错误的函数：

1	def get_displays(self):

2	return self.get_device('/displays','vga-out','mon').split(' ')

改成了：

1	def get_displays(self):

2	return filter(None, self.get_device('/displays','vga-out','mon').split(' '))

至于那个filter为什么可以去空元素，别问！还是搜索来的，其实我只是半个伸手党。具体自己看python文档，build-in函数里。
