求助：全新Acer Swift X SFX14-42G-R607安装Ubuntu时LiveUSB启动后卡住无法进入安装环境

大家好，我最近在给全新的Acer Swift X SFX14-42G-R607安装Ubuntu时遇到了棘手的问题，折腾好几天都没进展，想求助社区的大佬们！

问题详情 #

我分别用ubuntu-22.10-live-server-amd64.iso和ubuntu-22.10-desktop-amd64.iso制作了LiveUSB，启动时去掉了quiet参数并添加了nosplash，启动过程会输出一系列AMD GPU初始化日志，然后卡在Begin: Mounting root file system ...这一步彻底不动——拔掉USB会提示设备断开，但系统依旧没有响应。

启动时的完整日志（手动记录）如下：

已尝试的解决方法 #

• 禁用了BIOS中的Secure Boot
• 添加了nomodeset内核参数，没有任何效果
• 尝试了Ubuntu Mini版，但系统识别不到无线网卡，无法下载安装包
• 测试了其他发行版的LiveUSB，同样启动失败，还看到提示nouveau 0000:01:00.0: unknown chipset (b77000a1)

现在我哪怕能装一个纯终端的系统都满足了，有没有大佬遇到过类似的问题，或者有其他可行的解决思路？麻烦指点一下！
