从几个月前开始,我开始在 Firefox 中遇到与“r300_dri.so”相关的问题。我在 Firefox 的“about:config”页面上禁用了 Webgl,这样就停止了崩溃。然而,大约 2 周前(禁用 WebGL 后),每当我登录 Ubuntu 时,我都只能看到我的桌面背景,带有闪烁的图标、Unity 启动器和顶部栏。我可以右键单击以进入终端。我认为 Compiz 崩溃了(日志发布在下面)。Firefox 问题和桌面问题可能完全不相关,但我预感它们有一个共同的原因。
系统
- Ubuntu 16.04 64 位
- AMD Turion 64
- 4 GB 内存
- PATA IDE 硬盘
- 显卡:VGA 兼容控制器:Advanced Micro Devices, Inc. [AMD/ATI] RS482M [Mobility Radeon Xpress 200]
我尝试过的事情
- 将所有软件包升级到最新版本
- “2018 年 4 月更新”和“2018 年 3 月更新”中描述的过程如下:https://askubuntu.com/questions/9925...mpiz-segfaults
- 重新安装 libglib2.0-0
以上任何一种方法都不能解决问题。
我读过很多关于这个问题的帖子,但很多帖子听起来和我遇到的情况不一样。不过,如果我在寻求帮助之前错过了一条显而易见的途径,我深表歉意!

该报告以类似的方式延续:大量相同的错误。
我目前正在从 16.04 版的实时 USB(Unetbootin)启动,它似乎运行得非常好。不过,Ubuntu .iso 映像是几个月前下载的,那时我还没有遇到这些问题。
