我新建了一台新 PC，并使用 Ubuntu 20.04 进行双启动。我在使用 ryzen 3950x 时遇到问题，htop 和系统监视器无法识别 cpu（而不是 32 显示 1 个线程）。我必须用 acpi=off 启动它，因为 ubuntu 不会启动。是兼容性的问题吗？我的 BIOS 在构建 pc 时已更新（3 周前，B550 AORUS ELITE AX V2（修订版 1.0））你能帮我解决 htop/系统监视器中错误的线程数吗

我很困惑

我有一个带有 ryzen 4300U CPU 的联想 Ideapad。我读过带有内核 5.4 LTS 的 Ubuntu 20.04.1 LTS 由于 renoir 集成 GPU 与 AMD ryzen 4000 系列不兼容。

使用升级内核或 AMD 专有驱动程序的 Ubuntu 20.04.1，还是使用支持 ryzen 4000 系列的内核 5.8 的 Ubuntu 20.10 更好？

我刚刚在新的 thinkpad 495s 上重新安装了 kubuntu 20.04。

（图形）登录屏幕看起来很正常，只是缺少鼠标指针。但是，登录后，我的屏幕大多是黑色/灰色。启动控制台时（使用ctrl-alt-t），我可以从灰色中猜测它在那里，以便我可以输入sudo shutdown now.

但是，如果我用recovery模式开机，电脑几乎可以用了，只是我无法控制屏幕的背光：按fn-F5一下会弹出背光控制窗口，显示应该减少背光，但实际上没有任何反应。

编辑：显然，如果我在插入电源的情况下启动，显示器和背光都可以工作。

我不知道这两个问题是否相互关联。

我在 Ryzen 3 CPU 上将 Xubuntu 20.04 安装到华硕 X412DA 笔记本电脑上。

我已经正确设置了休眠模式，它确实可以工作，但它并没有关闭笔记本电脑的电源。

如果我从 CLI 或菜单开始休眠，屏幕会熄灭，但笔记本电脑会保持供电。

如果我按住电源按钮并强制关闭电源，一切都很好。当我再次打开它时，它会从休眠中恢复。

如何调试和解决此问题？

我最近购买了华硕 Zenbook 14 Q407IQ。它使用带有 Vega 6 图形的 Ryzen 5 4500U 处理器和 Nvidia MX350 专用 gpu。我已经尝试在笔记本电脑上安装 Ubuntu 20.04，它最初似乎工作正常，但运行起来非常热，并且在尝试显示动画时非常滞后，而且风扇总是非常响亮。

我最终发现它似乎没有正确配置为使用任一 GPU。它预装了专有的 Nvidia 440 驱动程序，所以我尝试将它更新到最新的 450 驱动程序，但它没有做任何事情。我还尝试访问 Nvidia X 服务器设置，但它只是显示为空白并带有退出按钮。然后我尝试使用xrandr --listproviders查看附加的图形驱动程序，但它只显示提供程序编号：0。对于其他人来说似乎也没有太多这种情况发生，但这可能只是因为 Zen 2 APU 是新的并且没有似乎经常与Nvidia GPU配对。我发现的唯一类似实例来自这篇文章来自 ArsTechnica 的也使用 AMD apu 和 Nvidia 设置并在 GPU 测试下，他们遇到了与我所拥有的问题非常相似的问题，并尝试了一些不同的解决方案，但最终放弃了尝试使其工作。我还看到一些人提到禁用其中一个 GPU 应该可以工作，但我的华硕笔记本电脑没有给我这个选项。在对可切换的 Nvidia/AMD apu 图形有更好的支持之前，是否暂时无法在我当前的设置中使用 Ubuntu？任何帮助将不胜感激。

两周前，我在我的 Amd Ryzen 5 1600 / Nvidia Gtx 1070 上安装了 Ubuntu 20.04，但 Ubuntu 不时完全冻结。

键盘和屏幕完全停止工作，鼠标有时能够继续移动。我试过使用神奇的 SysRq 键，但没有用。也尝试过alt+F1但也没有得到系统的任何响应。基本上我只需要按下电源按钮即可重新启动。

我怀疑Nvidia，但我不知道如何验证。

nvidia-smi显示驱动程序版本 440.100。

发现这些日志/var/log/Xorg.1.log.old显示我的计算机崩溃的时间。

我无法改变显示亮度来工作。我有一台配备 AMD Ryzen 4800u CPU 和集成 Vega 显卡的联想 IdeaPad 5。

我尝试了以下解决方案：Grub 属性 acpi_backlight、xbacklight、直接在 /sys/class/backlight/...、xgamma、xrandr、gdbus 和 setpci 中更改背光。

我按照这些答案的说明进行操作，但没有一个有效：

我可以看到，例如 xrandr 或 xgamma 或背光的值已设置，但它们对笔记本电脑的显示没有影响。

我猜它与AMD驱动程序有关，但我不知道......

现在我不知道进一步搜索的方向。也许它是一个驱动程序或内核的东西。

那么，有人可以帮忙吗？:)

精简版

在 Ubuntu 20.04 上，内部和外部显示器无法同时工作。只能在内部使用默认驱动程序，或者只能在外部使用手动安装的 NVIDIA 驱动程序。帮助！

我的系统是华硕 TUF A15 游戏笔记本电脑 (FA506)。它具有带集成显卡的 AMD® Ryzen™ 7 4800H 处理器和 NVIDIA RTX 2060。

  • 全新 Ubuntu 20.04 安装
  • 需要nouveau.modeset=0在 grub 条目中设置以使图形工作
  • 未检测到外部显示器
  • Ubuntu 20.04 在 Additional Drivers 对话框中不显示任何内容
  • 安装nvidia-driver-440和运行nvidia-xconfig使 nvidia 卡工作，但仅检测到外部显示器（usbc 端口上的 displayport），内部显示器不工作
  • 只能通过删除/etc/X11/xorg.conf并重新启动来切换回内部显示器，但随后会丢失外部显示器和未使用的 NVIDIA 驱动程序
  • nvidia-xconfig可以通过再次运行并重新启动切换回 NVIDIA

长版

在全新的 Ubuntu 20.04 安装（启用安装专有软件）后，笔记本电脑启动到带有文本的背景屏幕

[    7.779369] ucsi_acpi USBC000:00: PPM init failed (-110)

其次是

在此之后，我可以访问终端。根据互联网建议，我可以通过更改以下行来修改 linux grub 条目/etc/default/grub：

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

至

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nouveau.modeset=0"

并运行

sudo update-grub

重新启动后，我得到 gdm 登录屏幕并可以登录到图形会话，但如果我连接外部，则不会检测到它。xrandr通过 DisplayPort-USBC 和 HDMI 连接或不连接外部显示器的输出是

xrandr: Failed to get size of gamma for output default

default connected primary 1920x1080+0+0 0mm x 0mm
   1920x1080     77.00*

Nvidia 驱动程序尚未安装，因此我首先使用 和 更新系统sudo apt update并sudo apt dist-upgrade重新启动。我检查了软件和更新的附加驱动程序选项卡，但它显示“没有可用的附加驱动程序”。跑步ubuntu-drivers devices什么都没有。

下一个最佳建议是通过 apt 安装 nvidia 驱动程序

sudo apt install nvidia-driver-440

重新启动后，监视器情况没有改变，仍然只有内部监视器。xrandr输出相同，但现在安装了 Nvidia 驱动程序。nvidia-smi显示：

nvidia-settings显示一个小的空窗口。启动来自终端打印：

ERROR: Unable to load info from any available system

** Message: 09:45:58.789: PRIME: No offloading required. Abort
** Message: 09:45:58.789: PRIME: is it supported? no

现在我运行sudo nvidia-xconfig生成/etc/X11/xorg.conf. 重新启动后，外部监视器正在工作，我在外部（显示端口）监视器上看到了正常的 gdm 登录屏幕，并且可以登录到图形会话。遗憾的是，内部显示器不再被检测到，只显示华硕标志。nvidia-settings对话框现在具有我期望的所有选项（从终端启动会提供与以前相同的输出）

根据kanehekili输出的要求，xrandr -q现在是：

请帮我解决这个问题

从我的互联网搜索来看，我并不是唯一一个与这种 AMD/NVIDIA 混合图形配置作斗争的人。圣杯将是两个显卡的无缝集成，以尽可能节省电池，并在需要时使用独立显卡，但我很乐意在两台显示器都工作的情况下满足永久耗电的英伟达！

根据我的研究，问题的核心是 nvidia 卡硬连线到显示端口，集成显卡连接到内部显示器。理想情况下，nvidia 可以渲染到可以复制到集成显卡的缓冲区，但我不知道具体细节，也不知道如何配置它。

注意：一些互联网建议建议在安装 nvidia 驱动程序之前添加 nvidia ppa：

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update

我过去曾尝试过，但没有区别，该 ppa 和 ubuntu 存储库中的 nvidia-driver-440 包是相同的版本440.82+really.440.64-0ubuntu6，并且“附加驱动程序”选项卡没有变化。

另请注意：我已禁用安全启动

编辑：这篇文章Ubuntu 20.04 无法识别第二台显示器

建议安装nvidia-driver-435，但在我的情况下，这并不能解决问题。

我对自己的问题有部分答案，但仍然需要帮助。

在阅读了这篇 reddit 帖子后，我开始怀疑 Ubuntu 20.04 中的内核版本 5.4 对最新的 AMD APU 没有很好的支持。为了测试这一点，我使用此处的说明安装了最新的内核 5.6.15 。安装了较新的内核后，我现在可以在集成显卡上运行时将 HDMI 端口用于外接显示器。那就是删除 xorg.confsudo rm /etc/X11/xorg.conf并重新启动。但是当使用 nvidia 卡时，我仍然只能使用 displayport（在 usbc 上）。我仍然希望能够在内部显示器上使用 NVIDIA。

我的带有 Ubuntu18.04 的 Thinkpad E495 在关机/重启时停止/冻结在黑屏中。尽管如此，即使我需要通过电源按钮硬关机，它也能正常启动。在 grub 中禁用quiet splash，但在关闭时它不显示任何日志。我尝试用sudo reboot -dor重启，sudo reboot -f但它仍然以黑屏结束。

系统规格：AMD Ryzen 5 3500U 集成 AMD Radeon vega Graphics
