linux nvidia fonts session

Fonts in desktop environment always change across reboots

On my Archlinux, I installed proprietary nVidia drivers because of the presence of an nVidia card.
Unfortunately, each time I reboot, I have to set the fonts through the desktop environment in order to have the correct font size.

It's a DPI detection problem

According to some community posts, it has to do with DPI detection

Hard seting the DPI

The solution I choosed is to edit "/etc/X11/xorg.conf" and add
  Option "DPI" "96 x 96"
in the "Monitor" section.

The "Monitor" section becomes:
Section "Monitor"
 Identifier "Monitor0"
 VendorName "Unknown"
 ModelName "Unknown"
 HorizSync  28.0 - 33.0
 VertRefresh 43.0 - 72.0
 Option  "DPMS"
 Option "DPI" "96 x 96"
EndSection
Don't touch other sections unless you know what you're doing.
Reboot and enjoy.

npm run build base-href

Using NPM to specify base-href When building an Angular application, people usually use "ng" and pass arguments to that invocation. Typically, when wanting to hard code "base-href" in "index.html", one will issue: ng build --base-href='https://ngx.rktmb.org/foo' I used to build my angular apps through Bamboo or Jenkins and they have a "npm" plugin. I got the habit to build the application with "npm run build" before deploying it. But the development team once asked me to set the "--base-href='https://ngx.rktmb.org/foo'" parameter. npm run build --base-href='https://ngx.rktmb.org/foo did not set the base href in indext.html After looking for a while, I found https://github.com/angular/angular-cli/issues/13560 where it says: You need to use −− to pass arguments to npm scripts. This did the job! The command to issue is then: npm run build -- --base-href='https://ngx.rktmb.org/foo&
