After trying Manjaro KDE (Lysia) on a virtual machine for a few weeks, I yesterday installed it natively on a Dell Precision M4800, using the free drivers. The installation went well but the display resolution was set to maximum (3200) which made icons and text too small for my eyes. I changed resolution to 1920x1080 and the screen went black. I rebooted but after login the screen went black again.
As I didn’t know what else to do, I reinstalled Manjaro, this time using the non free drivers. This made for larger text but the resolution was still 3200 and I wasn’t able to change it to a lower resolution. Unfortunately, the installation stopped at 82% during “configuring hardware”.
I then installed it a third time, now using the free drivers again. After completion, I didn’t dare touch the resolution settings and only changed the magnification to 150%. This made the text look good but the icons were still too small. I opened System settings, selected Hardware configuration and tried to install the nvidia drivers but the installation failed (saying something about “core” missing).
Please advice! The native resolution for my display is too high and I need to lower it or use magnification that affects the icons too.
If you are running 5.6 kernel you should NOT update right away - it’s not EOL - it’s not supported anymore. First, you need to install a supported kernel (e.g. 5.4 or 5.8) and then boot into it, remove 5.6 and then update.
Thanks for trying to help, btw. If I change the resolution and the screen goes black again, is there something I can do besides starting all over again? Is there someway to revert the display settings?
Honestly … I dont know whether or not to trust pamacs output … especially since you started from an old ISO.
I would do this to be sure:
sudo pacman-mirrors -f && sudo pacman -Syyu
So first … you are currently using the open ‘nouveau’ driver.
Pretty much universally you get better results from using their proprietary drivers.
(assuming your card is supported)
As yours seems to be … you probably want to install whatever is best for you … I guess ‘video-nvidia-418xx’.
Its totally up to you … but heres an example of the install: sudo mhwd -i pci video-nvidia-418xx
From there … I would say you dont want to mess with your resolution.
It should just be set to its automatic/optimum max.
From there you probably want to either set ‘Scaling’ in Display Configuration
Or use a combination of DPI settings.
Start by using the ‘global scale’ setting … if that is not to your liking I will show you the DPI route.
Just by reading this thread I have been learning so much! My past 48h was exactly about this, as a total noob I have came to the exacvt same conclusion regarding kernel use: LTE or the latest non experimental, nothing in between. I Reinstalled my OS and the kernels like 15 times in 48h to learn this and figure this “optimal kernel” versio out on my RTX270+8700K PC by seeing its performance and visual glitches (tearing etc).
Thanks but are you saying I should run your one-liner if my screen goes black? Because I can’t see anything then. In Windows, the system reverts back to previous settings if the user doesn’t accept the new settings. I was looking for something like that. Or perhaps doing something from the boot screen.
I actually had the same problem when trying to boot LiveCD with KDE of Manjaro 20.2 on my 4K laptop.
All elements, icons and text on my monitor are extremely small. And it is not possible to change scale without reboot. And since it’s a LiveCD, as you know, there is no point in rebooting.
