If you want to add ignored files in Pastic SCM, there is no --force option like for instance git has. The only way is to:
ignore.conf file so the affected files are not ignored any moreignore.conf changeSource: [WayBack] plasticscm – Plastic SCM: Add ignored file – Stack Overflow

For a keyboard-less Raspberry Pi machine that functions as a read-only screen, I needed:
I already had the E20 ([WayBack] Enlightenment) X11 server running as that’s the first image on [WayBack] HCL:Raspberry Pi3 – openSUSE that as a graphical UI that works.
Basically this is editing /etc/sysconfig/displaymanager and replacing the line
DISPLAYMANAGER_AUTOLOGIN=""
with one like
DISPLAYMANAGER_AUTOLOGIN="username"
After rebooting, the X11 session will automatically logon without asking for a password.
You can do this via yast too, in at least two ways:
Both posts are titled how to disable automatic logon, so apparently people do this the other way around but forgot how to restore.
This is done using x11vnc which exposes the X11 framebuffer over the VNC protocol (more background from the author at[WayBack] x11vnc: a VNC server for real X displays).
Steps to get this working:
sudo zypper install x11vncsudo su username to the user that needs to logonx11vnc -storepasswd (which is a VNC specific password you can choose yourself):
x11vnc -storepasswd
Enter VNC password:
Verify password:
Write password to /home/martijn/.vnc/passwd? [y]/n
Password written to: /home/martijn/.vnc/passwd
x11vnc with the stored password (unlike LXDE where the directory is `x11vnc.desktop, with E20 the directory is ./.local/share/applications):
cd ~/.local
mkdir share
cd share
mkdir applications
cd applications
cat > x11vnc.desktop
-shared option if you want only one VNC client at a time; see[WayBack] xorg – How to setup multiple simultaneous access to x11vnc session – Ask Ubuntu and[WayBack] Set up VNC so that multiple users can use VNC · Issue #1 · acrobotic/Ai_Demos_pcDuino):

[WayBack] macos – El Capitan /private/var/folders cache files consuming 30–40 GB – Ask Different
TL;DR: a reboot will usually clean up most of the chaches and yes you can remove those caches by hand after closing the applications involved.
