    Issue

On SuperMicro AS-4124GS-TNR server with ASPEED AST2500 BMC, Proxmox 7.1 installation does not start with "installation aborted" message.
Details

After setting up DHCP and Chrony, Proxmox fails to start the graphical installer and drops into the shell:
...
Starting Chrony for opportunistic time-sync... Starting a root shell on tty3.

Installation aborted - unable to continue (type exit or CTRL-D to reboot)
root@proxmox:/#

An attempt to start the X server with startx fails:
...

The X log file (/var/log/Xorg.N.log) shows a Segmentation fault:
Fatal server error:

or alternatively a Signal 6:

Solution

Using xorg.conf file, disable modules glx and glamoregl, also change modesetting driver to fbdev.
Details

Create and edit the xorg.conf file:
Xorg -configure
mv xorg.conf.new /etc/X11/xorg.conf
nano /etc/X11/xorg.conf

Make the following changes:

Find the line: Load "glx" and replace with Disable "glx".
After that line, add Disable "glamoregl".
Find the line: Driver "modesetting" and replace with Driver "fbdev".
Start the X server with startx which will automatically start the graphical installer.
