I'm connecting my board to a 55" 4k screen but when i start the desktop environment everything is small and hard to distinguish
<Darkmatter66>
what's the best way to get the DE recognise the big screen and adjust it's sizing
<Darkmatter66>
there are all kinds of trick like using a patched xrandr and increasing the font sizing but they all seem like hacks and don't normally result in a very good looking desktop

Darkmatter66: which desktop ?

narmstrong, xfce4, I think I've tried lxde before and it had the same problem
<narmstrong>
xfce doesnt handle hidpi displays
<Darkmatter66>
narmstrong, right now I test cinnamon and set the scale to hidpi
<Darkmatter66>
narmstrong, what desktops do ?

gnome3
<Darkmatter66>
narmstrong, but why do we need to set the scale factor anyway? doesn't the drm driver advertise the screen size and resolution ? can't that be used by desktop environment to calculate the scaling ?
<Darkmatter66>
narmstrong, gnome3 works out of the box or require scale setting ?
<narmstrong>
yes drm adversises, but the feature to scale is hidpi
<narmstrong>
gnome, kde & co does it because the frameworks (gtk, qt) handles it
<Darkmatter66>
narmstrong, yes I mean the desktop environment should scale down or up based on what the driver advertise without the need for the user to manually set it to scale
<narmstrong>
yes
<Darkmatter66>
kinda like responsive design in websites
<Darkmatter66>
narmstrong, yes I've read this article, it says that xfce support hidpi but I can't get it to work
<Darkmatter66>
narmstrong, cinnamon warns me that it's running in software mode and i should check the gpu drivers, how can i check if the lima driver is being used or not ?
<Darkmatter66>
narmstrong, does lima support x11 at this point ?
<narmstrong>
Darkmatter66: it does if you take mesa from the master branch
<Darkmatter66>
narmstrong, hmm ok I will try it tonight, but how can i test if Xorg is using the gpu ?
<Darkmatter66>
narmstrong, I'm using this xorg.conf https://0x0.st/zlm4.txt would that be sufficent ?
<narmstrong>
you may need to specify the dri card, card1 would be the display, and card0 would be the gpu, but you must give the display card to X11, not the gpu card
<narmstrong>
but it may be ok with the config you showed me

narmstrong, how to detect if I'm using HW acceleration or not ? google tells me that glxinfo is the right way, but right now it tells me that hardware acceleration is enabled while cinnamon complains about video drivers
<Darkmatter66>
narmstrong, I'm still not using mesa from master branch I thought i give the already compiled version a go first, Xorg works but I'm not sure if I'm using the gpu
