GTX 1050TI Unknown Display

Post by lucasgvarela » 2019/11/02 14:59:13

Hello,

So, after a newly and fresh install, I'm can't change my resolution.
I never used CentOS as Workstation before, so my knowledge to displays/graphical cards are almost 0...

My resolution is setted as 800 x 600 using Displays I can see a message: Unknown Display and I don't have any other resolutions options.

My computer is an Avell A52-5 BS using a GTX 1050TI.

[root@localhost ~]# lshw -numeric -C display

What's the output from lspci -nn | grep -i vga.
Check /var/log/messages for mentions on 'nouveau'.
What is the output from uname -a - if the kernel version is less than 3.10.0-1062.4.1.el7 then you need to run yum update and reboot to get up to date.
What is the contents of /proc/cmdline
CentOS 5 died in March 2017 - migrate NOW!
CentOS 6 goes EOL sooner rather than later, get upgrading!

nomodeset rhgb quiet
Remove all of those from the grub kernel command line. Both nouveau and intel drivers require modesetting and the rhgb quiet parameters just hide useful debugging information.

Since you have two graphics cards, you may also need to code an xorg.conf file to tell it which one to use. You may also need to look at using bumblebee though I have no idea if that works on el8.

Based on https://wiki.centos.org/HowTos/Grub2 I have done:

Changed the /etc/default/grub GRUB_CMDLINE_LINUX option to (removed the nomodeset rhgb quiet):
GRUB_CMDLINE_LINUX="crashkernel=auto resume=/dev/mapper/cl-swap rd.lvm.lv=cl/root rd.lvm.lv=cl/swap"

Regenerated the grub.cfg file
# grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg
Generating grub configuration file ...
Adding boot menu entry for EFI firmware configuration
done

1 - Should I restart the machine right now or do you think I need to create the xorg.conf first?
2 - About the xorg.conf, how should I create this file (there is a template for that?), do you have an official documentation so I can follow?
3 - And sorry about that question, what is bumblebee?

And thank you for all the help until now :D
