Step 1 - In the installers boot menu press the E key
Step 2 - In order to get to a tty you need to blacklist your gpu kernel module using the modprobe.blacklist kernel parameter. After doing this, press enter. Example:modprobe.blacklist=amdgpu
Step 3 - Switch to a TTY (CTRL + ALT + F2) and log in with root/root.
Step 4 - Run lspci to get Bus Id of gpu. e.g 09:00.0 VGA compatible controller: Advanced Micro Devices
Step 5 - Use your preferred text editor to create the file /etc/X11/xorg.conf.d/fbdev.conf using the bus ID like this.
Section "Device"
Identifier "card"
Driver "fbdev"
BusID "PCI:9:0:0"
EndSection
Step 6 - Use that same text editor to edit /etc/X11/xinit/xinitrc and replace the last 5 lines with your desktop X11 command of choice. (startplasma-x11, budgie-desktop, etc).
Step 7 - Run startx, and start the installer.
You may have trouble entering the timezone. Instead of clicking the map use the textbox to search.
Step 8 - After installing reboot and hold the S key to pull up the boot loader before the system can boot, and then press the E key.
Step 9 - Repeat step 2
Step 10 - Switch to a tty, and log in with the account info you set in the installer.
Step 11 - Run sudo eopkg up, and reboot.
