Ubuntu 终端启动Qt时，报错
ss@ss-R458:~$ sudo qtcreator
Qt at-spi: error getting the accessibility dbus address: "Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."
Accessibility DBus not found. Falling back to session bus.
然后 虽然Qt打开了，但是特别卡，打开的项目根本运行不了。
请问是怎么回事啊？
