我在 ubuntu 18.04 上遇到了gnuplot(版本 5.2 补丁级别 2) 问题。尝试使用右键单击按钮缩放时，窗口消失。
我将其删除并重新安装，但问题并未得到解决。
崩溃时我的journal输入如下

我不太擅长解释段错误，因此非常欢迎任何帮助！
另外，在绘图时，在画布弹出之前，我在终端上收到以下内容：

答案1
我建议通过以下方式从官方存储库重新安装 GNUPlot 和库：
sudo apt-get install --reinstall gnuplot libwxgtk3.0-0v5 libpango-1.0-0
并检查其功能。
要修复视频驱动程序可能存在的问题，vainfo请安装sudo apt-get install vainfo并检查其输出。要获得 Nvidia 的视频加速，请安装以下软件包，它提供nvidia_drv_video.so图书馆：
sudo apt-get install vdpau-va-driver
重新启动并重试启动 GNU Plot。
