Shiqi's questions

我的笔记本电脑是hp spectre x360 13，我的操作系统是Ubuntu 18.04.4 LTS. 我想使用一个名为paraprof(here)的基于 Java 的应用程序。抱歉，我不使用 Java，所以我将它的部分描述放在下面（不知道它是否有帮助）：

ParaProf requires Oracle / Sun's Java 1.5 Runtime Environment for basic functionality.
Java JOGL (included) is required for 3d visualization and image export. Additionally,
OpenGL is required for 3d visualization.

问题是当我启动它时，字体太小而无法阅读：

我认为这是高 DPI 显示器上的缩放问题？我的笔记本电脑的内置显示器是3840 * 2160，在setting - screen display部分我将Scale选项设置为300%。

我之前也遇到过类似的缩放问题，字体大小spotify也确实很小。我通过添加alias spotify="/snap/bin/spotify --force-device-scale-factor=3.5"我的bashrc文件解决了这个问题。我想知道是否有类似的解决方案。

我看到有人建议在-Dsun.java2d.uiScale=2.0 这里使用，但我不确定如何使用它。

这发生在我在我的Ubuntu 18.04.4 LTS. 我发现Skype没有声音，所以我搜索了解决方案。有人建议安装pavucontrol

sudo apt install pavucontrol

之后，它并没有解决我的 Skype 问题，并导致我的笔记本电脑丢失音频输出。

我在网上尝试了一堆解决方案，但没有一个有效。这是我已经尝试过的解决方案。

# solution 1
pulseaudio -k && sudo alsa force-reload

# then I did
pacmd list-cards

# which gives me
0 card(s) available.

# I also tried
aplay -l
aplay: device_list:270: no soundcards found...

#solution 2
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get autoremove

sudo killall pulseaudio
rm -rf ~/.config/pulse
pulseaudio -k

我尝试了这些并重新启动了我的笔记本电脑。但它们都不起作用。我的笔记本电脑是hp spectre x360. 有什么建议么？非常感谢！

更新

我从这里运行了 alsa-info 脚本。这就是我得到的：
