问题[nvidia](ubuntu)

全新安装 Ubuntu 24.04 后，我注意到每当有全屏视频（使用 mpv）或全屏游戏（通过 Steam）时，主显示器总是会流到通过 HDMI 到 HDMI 连接的第二台显示器。

 - Distro : Ubuntu 24.04.2 LTS 
 - Kernel : 6.8.0-53-generic 
 - Nvidia : 550.144.03 (recently upgraded from 535). The same issue happens with 535.
 - Vulkan : 1.3.275 
 - OpenGL : 4.6.0
 - Windowing system : X11

mpv： 使用 mpv 全屏播放的任何内容都会溢出到第二个屏幕的一半。我能够x11-bypass-compositor=yes在 中强制执行mpv.conf，现在全屏 mpv 再也不会溢出到第二个显示器。

[更新 2025 年 2 月 22 日]
此修复显然不适用于 mpv。之前我尝试播放随机视频（我没有检查分辨率），它不再出现渗色，但最近我播放了一些 1080p 视频，它们仍然渗色到第二个屏幕。

steam： 我尝试使用相同的参数运行 steam flatpak run --env=__GL_X11_BYPASS_COMPOSITOR=1 com.valvesoftware.Steam。不幸的是，全屏游戏仍然会渗入到第二台显示器，而 steam 应用程序本身即使在全屏模式下也不会渗入。使用此参数，打开游戏也需要大约 2 分钟，与在我的旧 22.04（同一台机器）上运行相同设置相比，这非常不寻常。除了渗入和打开游戏时延迟很大之外，游戏之后运行良好。

它看起来像这样：

除了暂时修复的全屏视频外，只有全屏游戏会遇到此问题。其他应用程序均未遇到同样的问题。我还能尝试其他什么来阻止此显示器的闪烁吗？我尝试了 2 个 nvidia 版本（535、550），但都没有解决问题。在 24.04 之前也没有发生过这种情况，在 22.04 上，我能够使用双显示器顺利玩游戏。

我最近在 Ubuntu 上玩了很多游戏，但是我的方形显示器帮不上什么忙，因为游戏在上面看起来不太好。我完全不介意使用黑边，但我的问题是，我尝试过的所有更改分辨率的方法都不起作用，因为我无法选择任何非 4:3 的分辨率。我在其他操作系统上都做得很好，在 Ubuntu 上也可以吗？

抱歉，编辑前没有说明，我的电脑是一台旧的 HP Prebuilt（可以称我为老式电脑），具体来说是 HP Prodesk 600 G1 TWR。它有一个第四代英特尔 i5 CPU 和一个 GT 730 GPU。还有 8 GB 的 DDR3 RAM。我使用的是我认为是最新的 Ubuntu 版本（24.04.1 LTS）。另外，我不是 4:3，实际上是 5:4（1280x1024）我尝试使用 Ubuntu 设置，因为终端有时对我来说是个问题，当然这不起作用。我还使用 xrandr 命令尝试为此添加新模式，但在添加时，它似乎不起作用。

我最近将 GPU 从 GTX 1060 更新为 RTX 4060 Ti，但我的桌面图形分辨率总是很低。我尝试了在论坛上找到的几种方法来卸载、清除等驱动程序，但没有任何解决方案。因为 GPU 甚至没有被检测到。

也许一些旧配置阻止我正确升级 GPU？还是我遗漏了一些步骤？所以我的问题是：如何在不重新安装操作系统的情况下将旧图形配置重置为新 GPU 的全新安装？有办法吗？

如果需要任何额外的信息，请随时询问。

提前感谢您的回答。

命令之后

sudo apt-get update
sudo apt-get upgrade

我尝试使用命令刷新我的 nvidia 驱动程序，但出现错误：

我尝试了所有能找到的解决方法，但都无济于事。所以我终于破解了，并创建了一个帐户，试图找到答案。

我更新了我的视频驱动程序，但突然我的 pipewire 在重启时停止了工作。

输出

请帮忙！

我使用 Ubuntu 24.04 和 4k 显示器。在 X11 上，我设置了 60 Hz，使用UFO Test网站进行测试时，我得到了 60 FPS。

当我尝试 Wayland 时，设置显示它也设置为 60 Hz，但它绝对不是 60 Hz，而且当我使用 UFO Test 进行测试时，它仅显示 30 FPS。

我已经nvidia-driver-550。我用驱动程序测试了 PPA nvidia-driver-560，但仍然遇到同样的问题。

可能是什么原因呢？

屏幕撕裂出现在屏幕下方约三分之二处的特定水平线上（见下图）。

如果我将分辨率从 4K 改为2K，然后再改回 4K，问题就会消失，因此分辨率更改期间发生的任何情况似乎都会产生积极影响。但是，重启系统后，屏幕撕裂再次出现。

我附上了一张用手机拍摄的照片，因为我无法使用内置软件捕捉视频或屏幕截图。

• 我在 Ubuntu 24.04.1 上进行了全新安装
• Nvidia 专有驱动程序 550
• Nvidia RTX 4070
• 华硕 PB287Q 显示器，分辨率为 4k（3840*2160）。

我在此过程中没有遇到任何错误。最后我的背景变黑了，但我放弃了……我查看了其他带有 Oh No 屏幕的答案，但我的情况似乎不同，因为我无法通过 ctl alt f3 或其他按键变化进入登录屏幕。

我从 gdm3 改成了 lightdm，现在我可以进入启动登录屏幕了。不幸的是，当我登录时，它又回到了 Oh No 屏幕。我的触摸板可以移动鼠标，但不能点击。

我插入了一个外接鼠标，现在可以尝试不同的桌面选项了。选择 Wayland 后屏幕变黑，但 OpenBox 确实可以工作。所以我不再认为这是 nvidia 驱动程序的问题。也许这与我的触控板有关？？

此时还有什么提示吗？

Ubuntu 24.10
Wayland
Nvidia MX330
Nvidia 560.35.03

我被告知，运行 Nvidia 卡的先前问题已在 Ubuntu 24.10 中的 Wayland 下得到修复。

因此我从 24.04 升级到 24.10 并在 Xorg 下运行，解决了一些升级问题，并且它似乎运行良好。

然后我启用了 Wayland。虽然出现了一些小问题，但运行良好。我决定将 Nvidia 置于“性能模式”，一切似乎都很好，直到我检查nvidia-smi并注意到只有 Nvidiagnome-shell正在加速。

在这里我通过 CLI 显示选择了 Nvidia 性能模式...

这里显示了 Xorg 下的性能模式的 GUI……

这是nvidia-smi在 Xorg 下运行的...请注意加速的全部进程...而在 Wayland 下它只显示gnome-shell...

所以我的问题是...这是 Wayland 还是 Nvidia 的问题？我可以采取哪些步骤来进一步排除故障并修复它？

更新：所以我从 24.04 升级到 24.10 并在 Xorg 下运行，解决了一些升级问题，并且它似乎运行良好。

我发现在“性能模式”下，我无法在 Xorg 中打开桌面上的文件夹。“按需”模式则工作正常。

启动或重启后，许多应用程序启动非常慢。

• Firefox：正常
• Android Studio（手动安装，不是 snap）：正常
• GIMP：正常
• Nautilus：速度很慢，改用白色主题（顺便说一下，我使用深色主题）
• LibreOffice：缓慢
• Inkscape：慢
• Gnome 终端：根本无法打开

然而经过很长时间后，可能 10 分钟或几个小时后，一切就都正常了，所有应用程序都可以正常启动，即使 Nautilus 使用了深色主题。

我发现了另一个问题，但解决方案与我的无关，可能是因为它是 Ubuntu 19.10 而不是 24.04。

如何解决这个问题？或者至少，如何调试这个问题，这样我才知道如何报告这个错误。
