我无法弄清楚我得到的这个错误:
X Error: BadMatch (invalid parameter attributes) 8
Major opcode: 62 (X_CopyArea)
Resource id: 0x4e00004
我想在一个应用程序的两个监视器上显示两个小部件。 我使用以下屏幕配置(单个桌面,多个监视器)配置了我的目标: Screenshot
奇怪的是它适用于Suse下的旧X-Server。在Ubuntu下它没有。
以下是源代码和X-Versions
顺便说一下:
我必须使用这个配置(两个屏幕上必须没有虚拟桌面),我只是想了解它为什么不起作用。
- 相同的dirver
- 所以qt-bug?
