Fedora 15 (Gnome 3) 上的多显卡

Question

我有 3 个显卡（令人愉快的）不幸。它们是 XFX Radeon 5750。每个驱动器通过 dvi 驱动 2 个显示器。我真的很难让这些在 Fedora 15（gnome 3）上运行。所以我的设置是 3 列，每列 2 个显示器（上部显示器倒置安装在每列中，以减少显示器之间的边框）。

当（图形）登录屏幕出现时，所有 6 个都必须是默认的蓝色条纹背景，但是当我登录时，事情变得有趣了。

在下面的 xorg.conf 中，您将只看到 serverlayout 中的 2 个屏幕，而其他 4 个已被注释掉。仅在 2 个活动屏幕的情况下登录效果很好（它甚至记得顶部是颠倒的，应该考虑在较低的上方，我不确定它存储此信息的位置，但我使用图形“显示”设置）

但是，一旦我取消对第三个屏幕或更多屏幕的注释，它就会在我登录时显示一条错误消息。这是那些友好的、不太有用的消息之一（哦，不！出了点问题。发生了问题，系统无法恢复。请注销并重试）。

如果我不使用 xorg.conf，则“显示”首选项窗格仅显示我的其中一张显卡上的两个显示器

感谢任何可以帮助我前进的人！（xorg.conf 然后是下面的 lspci，还有 xorg 日志）

xorg 日志（发布到 fpaste 由于它有多长。感谢 marcusw 的请求）

http://www.fpaste.org/r5ww/

在 xorg.conf 中启用所有 6 个监视器的 xorg 日志（它们都打开并显示蓝色，但随后会收到上述用户友好的错误消息）。 http://www.fpaste.org/X63H/

Answer 1

那么登录管理器屏幕工作正常吗？

尝试不同的桌面环境。其中一种不太现代的（如icewm）可能会起作用。

运行时xrandr将显示最大可能的屏幕尺寸（我的是 8192x8192）。您的 DE 是否正在尝试设置更大的屏幕尺寸？

您可以尝试在 xorg.conf 中指定屏幕尺寸，这样您就可以尝试像 800x600 这样的小尺寸并进行测试。但由于登录管理器可以工作，这可能无法解决问题。

另外，请检查 $HOME/.xsession-errors 文件。

您还可以尝试停止登录管理器，通过 ssh 连接到计算机，启动 X（没有登录管理器），然后手动启动桌面环境并尝试查看是否给出任何错误消息。
