(SOLVED) Screen too bright during installation

Hello, I'm trying to make a fresh Arch installation, never had an issue, but now I'm using a different PC, the brightness level is too high, but my LG monitor settings are normal, the monitor is connected to the hdmi port of my graphics card, I tried with the vga port but it's also too bright.

Re: (SOLVED) Screen too bright during installation

Is that an assertion? or a question?

What video hardware are you using?  Have you tried a different monitor?

I'm using a Radeon R5 230 Xfx and yes I have tried a different monitor.

Re: (SOLVED) Screen too bright during installation

The image you posted seems like it should be perfectly usable even if it's not your ideal.  Once you complete the installation you can tweak your installed system to be more to your liking.

Or is the current brightness really going to prevent you from being able to type commands and/or read output?  If so, have you explored /sys/class/backlight or related paths?  You can generally just write a number to a brightness file there to change it (in my case /sys/class/backlight/intel_backlight/brightness).  You can also try using `setvtrgb` if you want to completely change colors rather than just adjusting the backlight intensity.  For example, here is my preferred vt colorscheme:

setvtrgb - <<EOF
16,221,170,204,170,204,153,204,32,255,68,221,68,221,85,255
16,170,221,204,170,153,204,204,36,68,255,221,68,85,221,255
16,170,170,153,221,204,204,204,40,68,68,85,255,221,221,255
EOF

Though this is relatively low contrast.

I can't see a damn thing, that's what's keeping me from installing Arch, I wasn't aware of the
intel_backlight tip, but how can I change it when I can't see?

Sorry I must have misinterpreted the image.  It looks like there is a visible prompt there (though the photo is a bit blurry).  If there really is nothing visible, it may not be a brightness or color issue at all.

Re: (SOLVED) Screen too bright during installation

You could try booting with nomodeset, maybe it is something strange in the radeon driver.

When can I set the nomodeset? during grub?
