[求助] X11VNC无显示器模式连接后卡顿的问题

2019-4-9 12:40:07 | 显示全部楼层 |阅读模式
本帖最后由 weicx 于 2019-4-9 12:44 编辑

硬件:Raspberry Pi 3 B+
操作系统:Ubuntu MATE 18.04.2 (Bionic) 32Bit
镜像名称:ubuntu-mate-18.04.2-beta1-desktop-armhf+raspi-ext4.img

目前问题:
  新安装的系统,第一次安装使用HDMI显示器后安装了X11VNC和SSH,raspi-config只进行分辨率的更改以及
  目前X11VNC存在以下问题,通过VNC Viewer访问Ubuntu,X下画面很卡,偶而连接断开(排除网络连接不稳定的情况),正常接入显示器后一切正常,初步看日志应该是驱动加载问题看到有无法启用硬件鼠标和3D加速的信息,但是本人多方查阅无法修复,在此寻求各路大佬解决,万分感谢。

顺求各位使用Raspbian系统的大佬们默认VNC下xorg.conf配置信息。

附两个/var/log/Xorg.0.log文件,分别为默认和创建/etc/X11/xorg.conf后的log。

不创建/etc/X11/xorg.conf,默认V11VNC进行连接时的Xorg.0.log文件内容:

根据Ubuntu MATE官方网站的说明
Enable and Disable X11
You can disable/enable the desktop environment using raspi-config.

If you only intended to run as a headless server then the official Ubuntu Server 18.04.2 images mightt be of interest:
•https://wiki.ubuntu.com/ARM/RaspberryPi

官方Wiki摘录以下内容
Accelerated X driver
An accelerated x.org video driver is available (fbturbo), though this is limited to hardware accelerated window moving/scrolling on the Raspberry Pi. Install the optional PPA above, then:
$ sudo apt-get install xserver-xorg-video-fbturbo

Then add this to /etc/X11/xorg.conf (create if it doesn't already exist):
Section "Device"
    Identifier "Raspberry Pi FBDEV"
    Driver "fbturbo"
    Option "fbdev" "/dev/fb0"
    Option "SwapbuffersWait" "true"
EndSection

根据官方说明创建/etc/X11/xorg.conf,V11VNC进行连接时的Xorg.0.log文件内容:
