Title: Ubuntu with userland
Post by: LinuxGuy on January 03, 2020, 07:47:58 am

Hi folks,
I am pretty new here, with only a little Linux knowledge. I use it as main OS at home and backed the cosmo to have a tiny Linux Laptop on the go. As we are still waiitng for the promised nativ linux -support, I played aroudn with userland-app. I finallygot lxde running, but:
- all desktop elements are so tiny, that the system is unusable (forwordprocessing p.e.)
- changing configuration files to correct this fail, as the keyboard doesnt really match. Having a german keyboard, i choose plain german in the installation process (from 10 variants).
- external mouse (via usb-c) does not work

Any help would be appreciated.

Have you tried adjusting the DPI in X?  Most applications (using Qt, GTK, etc.) will respect it.

This article has useful information: https://wiki.archlinux.org/index.php/Xorg#D...ay_size_and_DPI (https://wiki.archlinux.org/index.php/Xorg#Display_size_and_DPI)
Try for example:
xrandr --dpi 192

Note you will need to restart applications so that they notice the change.  
Also note the bit about the optional Xresource Xft.dpi  
You may need to explicitly set this to the same value (e.g. 192)

Hi NormMonkey


thanks for your help.

Try for example:
xrandr --dpi 192

This doesnt work: "RandR extension missing" Also in reading the arch-wiki entry, I couldnt find a solution.
Any ideas?

Hmmm, if tweaking the Xresource Xft.dpi doesn't work either, then I don't have anything else off the top of my head.
I think you can tweak Xft.dpi using xrdb temporarily, and set it permanently in .XResources once you have something that works, but I'm just going by old memory so don't quote me on that

Discovered an  easy  fix:
in the linux--filesystem, just edit screen-resolution to your liking in ~/.vncrc - works like charm! Userland, once set up makes for a good Linux Option without need for reboot!
I use 1140x560
