How to Disable or Uninstall Synology Universal Search

Starting with DSM version 6.1 Synology has removed File Station from the core and swapped the Search functionality from File Station with its own package called “Universal Search“. I’ve noticed some users, myself included, don’t use this package and don’t even want it in their Synology; however, it cannot be disabled or uninstalled via Package Center.

[Howto] Use wayland with propietary nvidia drivers

Wayland does not play well with proprietary drivers. Currently the biggest issue is that nvidia does currently not support Xwayland properly, so apps that require it get software rendering. This includes most games, which are the most common use case for proprietary nvidia drivers. This is why gnome automatically disables Wayland if you have nvidia.

However, if this does not deter you, you can use Wayland with nvidia drivers. Here is how to do it:

  1. Edit the /etc/gdm/custom.conf file and comment out the line WaylandEnable=false. The correct file will then look something like this:
    
    
    # GDM configuration storage
    daemon]
    # Uncomment the line below to force the login screen to use Xorg
    #WaylandEnable=false
    
    [security]
    
    [xdmcp]
    
    [chooser]
    
    [debug]
    # Uncomment the line below to turn on debugging
    #Enable=true
    
  2. Now for the nvidia specific part: edit the file /usr/lib/udev/rules.d/61-gdm.rules and comment out the lines that disable wayland for nvidia. Note that this file gets overwritten by updates. The correct file looks something like this:
    
    # disable Wayland on Hi1710 chipsets
    ATTR{vendor}=="0x19e5", ATTR{device}=="0x1711", RUN+="/usr/lib/gdm-disable-wayland"
    # disable Wayland when using the proprietary nvidia driver
    #DRIVER=="nvidia", RUN+="/usr/lib/gdm-disable-wayland"
    # disable Wayland if modesetting is disabled
    #IMPORT{cmdline}="nomodeset", RUN+="/usr/lib/gdm-disable-wayland"
    
  3. Enable modesetting for nvdia drivers. Follow the instructions in the Arch wiki 5:
    • Add the modules nvidia , nvidia_modeset , nvidia_uvm and nvidia_drm to /etc/mkinitcpio.conf and run the command sudo mkinitcpio -P
    • Add the kernel parameter nvidia-drm.modeset=1 to /etc/default/grub and run the command sudo update-grub
  4. Reboot
  5. Profit. Congratulations, you should now be running gnome with wayland despite propietary nvidia drivers!

为Debian 10升级Linux Kernel 5.x

目前 Debian 10 自带的内核版本为 4.19,可能由于种种原因…比如不升级手痒,十分希望体验一下新版内核,这篇文章可以指导你如何正确的查询并安装新版内核。
以下方法同时也适用于未来以及先前的 Debian 版本,步骤一致,唯一的区别是将文中的 buster-backports 中的代号更换为你正在使用的系统的代号。

win10 WSL2: docker, systemd, etc

背景

由于新款Mac性价比走低,近期转为使用Windows作为主力开发系统。但是在开发过程中需要上Linux测试,或者说部署一些服务,例如MySQL,Nexus OSS等。本人又是一个Docker重度依赖者。之前一直是长期在Windows下启动一个Linux虚拟机辅助开发操作。占用大量磁盘内存资源不说,操作和维护也极为繁琐。

直到近期了解到Win10 2004正式版版本支持WSL2,问题得到了完美的解决。WSL2相比WSL1来说可以完美支持Docker。与WSL1的模拟Linux API不同的是,WSL2采用在Hyper-V虚拟机中运行的方案。可以说WSL2和原汁原味的Linux已经十分接近。本人实验了一番,安装部署成功,将整个步骤分享给大家。
