当我尝试使用 x2goclient 服务时,我收到此错误:
我该如何解决?
更新:两台计算机都在同一个本地网络上,没有防火墙,它们之间的 ssh 连接运行良好。两台电脑都运行 Ubuntu 18.04,软件版本:x2goserver 4.1.0.0-3和x2goclient 4.1.1.1-2。
我需要在 Zotac XBOX 上设置更高的分辨率。这是我在下拉框中看到的分辨率列表:
我需要选择这个 1680x1080 的分辨率。目前,如果我选择它,它不起作用并返回到当前选择的 1280x800。此分辨率由同一台 PC 上的 Windows 支持,而且我清楚地看到它在安装后首次登录 Ubuntu 时工作。但不知何故,后来它降级到了 1280x800。这是我的 xrandr 的输出:
我从 cvt 添加了最后一行,但正如我之前所说,它不起作用:
看来我需要更改视频驱动程序中的某些内容,但 ZOTAC 网站上没有 Linux 驱动程序。这里也没有驱动程序:
我还能尝试做什么?我清楚地记得,这个分辨率在这个 Ubuntu 18 上用这个硬件成功地工作了。
更新:设置不同的 crtc 也失败:
可能是显卡驱动的问题,这就是windows根据GPUZ使用这个设备的方式:
UPDATE2:有趣的观察:初始系统登录对话框有时具有很好的分辨率。而且,如果我安装 xorg intel 驱动程序,那么我得到了很好的分辨率,但是鼠标和键盘都死了。
更新3:我发现如果我断开PC与220V的连接,关闭显示器,然后重新启动一切,那么分辨率就很好。如果在我的工作期间屏幕保护程序启动或电缆重新连接,那么它会进入这个 1280x800 模式并且除了这个硬重启之外没有其他办法。(此设备在 Windows 上也有类似的问题,但不是因为那里的模式设置有限,而是在重新连接电缆后显示器有时根本无法恢复)。同样根据要求,这里是dpkg -l bolt的输出:
UPDATE4正如我所注意到的,屏幕保护程序会导致分辨率下降,所以我不得不以这种奇特的方式将其关闭:
我已经在 Ubuntu 18.04 上安装了 mate 和 xrdp。现在我尝试使用 Remmina 从另一个 Ubuntu 连接到这台 PC:
我按确定,登录窗口消失背景相同,没有任何反应。我的~/.xsession包含mate-session。
xrdp.log 包含如下内容:

如何修复或诊断这款出色的软件?
我没有对 jetson nano 机器的物理访问权限,但我想安装 DeepStream。由于依赖关系而失败:

如何在没有sdkmanager的情况下安装这些依赖项,这需要通过 USB 直接访问设备?我试图找到 arm64 的 cuda,但在 nvidia 网站上没有办法下载它们,只有 amd64。是否有带有cuda-cudart-10-0、libnvinfer5和其余部分的公共存储库。
我尝试下载 https://cmake.org/files/v3.11/cmake-3.11.0.tar.gz 并构建它,但是构建后 ./bin 子文件夹中没有 cmake-gui 。cmake-gui 是否在另一个源存档中提供?
