Hello everyone,

Something happened with my centos partition and now i cant enter to settings via gui.

Can someone explain how to go there using the command line?

What i want to do is to change the screen resolution and i dont know how to do it using the console. I read some old threads about it but im a noob and dont get it.

Thanks in advance

There's two separate things here: editing configuration settings from the command line and fixing whatever happened with the partition. The first lets you move on and forget you need to fix things good, so lets start with the second one: please describe in detail what happened, what (error) messages were shown (also see 'journalctl -xn' and /varlog/messages) and what you have tried to fix things yourself?

My bad, there is nothing wrong with the partition, i said that because i have 2 partitions on my drive, one with windows and one with centos.

Before yesterday i started updating centos but the computer start running super slow so i cancel the update. After that, when i restart my pc couldn't enter to centos, apparently some libraries got corrupted. I managed somehow to fix it and could enter to the OS.

Then i wanted to change the resolution of my screen. I went to Applications/System Tools/Settings and nothing happens. I also tried in my username (on the top right hand) and settings and nothing happen either.

This is happening after the corruption of the libraries.

So i need help with the screen resolution and i would like to fix the settings error.

Thanks!

bingo this is the problem
you can not even do that on windows
you end up with a FUBAR'ed system


reinstall cent

if you did that on windows you also would be reinstalling the operating system .

Well that never happened to me on windows, but im sure that if that happen you can recover the system with the cd. But yeah i got your point and i agree! I am a noob !

So you say the only solution is to re install cent?

There's a logical order in which to fix things. You may want to change your screen resolution but you must first fix underlying problems.


Did you run the update via Desktop Environment tools? And how did you cancel that update?


You said you "managed somehow to fix it" but you didn't tell us how. Without knowing that we could offer some suggestions but we may duplicate efforts which is not efficient. So be precise and verbose in what nfo you share.


No. John VV often suffers from taking short cuts. Obviously the first thing would be to diagnose what's actually wrong. (Unless you do not want to learn anything of course, then you'd just re-install the OS on every error in the hope it will make all errors go away automagically.) Troubleshooting starts by providing nfo requested above. Also look for errors in /var/log/messages since you last booted up the machine and run (as root): then look at the contents of "/tmp/verify.txt". An explanation of what you see you will find in 'man rpm' the "Verify options" part.
