Cant add new resolution on VGA monitor

I did a fresh install on my system.
I installed nvidia drivers, xorg and kde from official repo and my system booted perfectly for first time.
After this, i had a problem with my system not booting kdm and stopping to a certain point every time.
I found a solution for this on the forum, i added to

/etc/mkintcpio.conf

MODULES="nvidia"

and i did

mkinitcpio -p linux

but now im with resolution 640x480 while my monitor supports 1920x1080
the monitor is connected with vga cable and adapter to dvi
i tried to use my tv monitor with hdmi cable and everything works fine there

my xrandr

xrandr --addmode DVI-I-0 "1920x1080_60.00"

and i get this

Re: Cant add new resolution on VGA monitor

Hello,

Please post some hardware details, such as: nvidia card model, any integrated card (intel / ADM), laptop or desktop computer.

You can use the following command to configure xorg if not already done:

# nvidia-xconfig

Look at https://wiki.archlinux.org/index.php/NVIDIA#Configuring for further information about Xorg configuration with nvidia. You can also go to the nvidia control panel for advanced settings.

Re: Cant add new resolution on VGA monitor

Searching your GPU in google, I found this: https://teksyndicate.com/forum/linux/li … our/154452
It seems that you'll need to downgrade your kernel to make the nvidia drivers work. You can use the LTS Arch kernel (package linux-lts), which should work. Please post your results.
