在fedora10下启动两个超级玛丽(smc, supertux)出现的问题

大家好：
这两个游戏我是从yum安装的
启动后的问题，分别是：
[eorland@localhost ~]$ smc
ALSA lib pulse.c:266pulse_connect) PulseAudio: Unable to connect: Connection refused

Error : Screen mode creation failed
Reason : Could not create GL context
---------------------------------------------------------------------------------------------------------------------
[eorland@localhost ~]$ supertux
[/home/eorland/.supertux] is in the search path
[/usr/share/supertux] is in the search path
Invalid button '0' in buttonmap
Invalid button '1' in buttonmap
Invalid axis '-2' in axismap
Invalid axis '-1' in axismap
Invalid axis '1' in axismap
Invalid axis '2' in axismap
ALSA lib pulse.c:266pulse_connect) PulseAudio: Unable to connect: Connection refused

ALSA lib pulse.c:266pulse_connect) PulseAudio: Unable to connect: Connection refused

Fatal: Unexpected exception: Couldn't set video mode (800x600-0bpp): Could not create GL context

这两个问题，该怎么解决？
谢谢大家！！　　　　　　

将音频设备的权限改一下,或者以root身份玩游戏
