几周没有时间玩游戏后，今天我无法启动 Steam。
我不记得系统 = Linux Mint 20 中有什么比今天将我的 Mint 从版本 20.2 升级到 20.3 更大的变化了。
这是dmesg片段：
$ \dmesg --human --color=auto --ctime

如果我steam从终端运行，我会得到：
$ steam
steam.sh[7775]: Running Steam on linuxmint 20.3 64-bit
steam.sh[7775]: STEAM_RUNTIME is enabled automatically
setup.sh[7910]: Steam runtime environment up-to-date!
steam.sh[7775]: Steam client's requirements are satisfied
$
我没有更改内核，但我记得通过定期更新来更新它。唯一的红色的线路是：
kernel BUG at drivers/gpu/drm/drm_gem.c:154!
我现在运行的是 495.46 版本的 Nvidia 驱动程序。
PS：在 Windows 10 上，Steam 和游戏可以运行。
答案1
通过恢复到 Nvidia 驱动程序版本 470.86 解决了该问题。
所以，也许 495 驱动程序分支还没有准备好。无论如何，我把这个问题留给其他读者。
