我做了两件事:安装了这套新的浅色主题http://www.omgubuntu.co.uk/2017/05/install-improved-ambiance-gnome-theme(适用于 16.10 和 17.04,我使用的是 16.04,我没有注意到它不兼容)并通过添加其 ppa 和运行 dist-upgrade 来更新 mesa 驱动程序。
重启后,时钟指示器消失了,nautilus 的显示类似于 gnome,中央证券(带有 ubuntu 主题的黑角),桌面图标变大,全局菜单中只有“文件”部分,右键菜单不会显示某些部分,留下空白(您可以按它,它可以工作但没有文本)。
运行sudo apt remove light-themes=16.10+17.10.20170515.1-0ubuntu1
和安装后14.04+16.04.20160415-0ubuntu1它只解决了右键菜单问题。有人知道是什么原因导致了这些问题以及如何修复它们吗?

答案1
我不能肯定地说,但由于与系统不兼容,而且本身就有 bug,升级 Mesa 可能会导致这些问题。我之前升级 Mesa 和我的图形驱动程序时,它给我的机器带来了极大的麻烦,因为 Ubuntu 的设计只适用于某些版本,而不是最新版本,所以在很多情况下,它会把一切都搞乱。
有一个名为的实用程序ppa-purge
,您可以使用它来降级(到官方存储库版本)并卸载来自特定 PPA 的所有软件包,可以使用以下命令安装:
sudo apt-get install ppa-purge
跑步:
sudo ppa-purge ppa:ubuntu-x-swat/updates
应该可以解决您的问题,请确保在完成后重新启动。
