我有一台搭载Ubuntu 22.04的机器，配备了一张旧款AMD显卡（详细信息如下）。背景是，在过去的一年半时间里，它一直运行在Linux Mint上。在硬盘损坏的困扰下，几个月前我将其切换到了Ubuntu。
最后一次正确启动是3或4天前，我记得当时我在玩游戏的同时在后台运行了一个更新。然后我关机并尝试几天后重新启动。现在我无法启动Ubuntu桌面。它只能进入一个有闪烁光标的屏幕，并且我可以通过Ctrl+Alt+F2进入TTY。我也可以通过SSH连接到它。
我查找了一些解决方案并尝试了一些方法。我尝试手动启动Xorg，但没有成功。我还尝试在grub配置中使用nomodeset以使其启动，但出现了错误。我尝试重新安装了ubuntu-desktop。我还尝试以前的内核进行引导，但似乎遇到了相同的问题。我查看了xorg日志，但只找到了上一次进入系统时的日志和我手动尝试启动时的日志。我很难找到类似的情况，而且还要在最新版本的Ubuntu上解决。我一直在尝试运行任何Ubuntu的更新，以查看是否修复了问题。
我觉得这可能是内核和GPU驱动之间的问题，但这只是我从某个地方读到的线索，新版本的内核和amdgpu驱动可能存在问题。
多年来，我一直在使用各种Linux发行版，但并不是专家。就我的知识和搜索能力而言，我已经达到了尽头。所以任何帮助都将不胜感激。我刚刚把这个安装设置成我想要的样子，并且工作得相当好，所以我真的不想重新安装，特别是因为操作系统似乎除了图形界面之外都正常运行。
