最近安装了fedora系统，并且继续使用x11+xfce的经典组合，在安装玩nvidia驱动后，窗体各种闪烁、黑屏，甚至xfce的进程莫名卡死，系统如下：

在一篇神奇的贴吧指引下传送门，只需要把xfwm的vblank mode改一下就好了。

已经完美解决了，在xfce的论坛置顶上找到了解决方案
1. 使用 xfwm4 --vblank=MODE --replace 命令后启用合成看效果怎么样，MODE替换成（glx[默认]，xpresent或off）
2. 如果合适的话，使用 xfconf-query -c xfwm4 -p /general/vblank_mode -t string -s "MODE" --create 命令使其永久生效，"MODE"替换成（"glx"，"xpresent"或"off"）
亲测使用xpresent的时候解决了这个问题
ps：glx 适用于英特尔卡和一些nvidia / ati卡，xpresent 适用于较新的ati / amd卡，off 适用于nvidia卡

fedora43默认的模式是auto，只需要改成off就好了

xfwm4 --vblank=off --replace 
xfconf-query -c xfwm4 -p /general/vblank_mode -t string -s "off" --create

解决完闪屏的问题，原本以为万事大吉了，结果刚开steam就跳回lightdm了，通过 journalctl -xeu lightdm 查看日志发现

你的 XFCE 崩溃了，从日志来看核心原因是 Xorg (也就是 X server) 在 NVIDIA 专有驱动里发生了段错误 (Segmentation fault)，导致整个图形界面直接崩掉，然后 LightDM 尝试重启会话。
当前情况判断 (Fedora 43 时代典型问题)

崩溃发生在 nvidia_drv.so 内部（偏移 +0x4dc8b4 这个地址在不同驱动版本里经常出现）
Fedora 43 + 最新的 NVIDIA 驱动（580.105.xx 系列）在 2025 年底 ~ 2026 年初有不少人遇到类似的 Xorg 崩溃/黑屏/随机掉出问题
尤其在使用 Xorg/X11 会话（XFCE 默认就是 X11）的时候特别容易触发
部分人是新内核 (6.17.x) + 新驱动 + 新 xorg-server 的组合拳问题

提出的解决方案是降级x11然后重建nvidia模块

# 降级x11
sudo dnf downgrade xorg-x11-server-Xorg xorg-x11-server-common

# 重建akmod
sudo akmods --rebuild --force
sudo dracut -f --regenerate-all   # 可选，但建议一起做
sudo reboot

最后锁定一下版本

# 装yum插件
yum install -y python3-dnf-plugin-versionlock
# 锁定版本
yum versionlock add xorg-x11-server-Xorg xorg-x11-server-common

这个问题算是比较好解决的，通过google搜索，在reddit和stack overflow也有很多类似的问题，不过归根结底，不用n卡就好了（确信

祝好运～ Fedora 43 这段时间 NVIDIA 的确是地狱模式，很多人都被虐得很惨…… 😓
