Resolve Proxmox 7.1 "installation aborted" on SuperMicro with AST 2500


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


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)

An attempt to start the X server with startx fails:

he log file at "/var/log/Xorg.1.log" for additional information.(EE) (EE) Server terminated with error (1). Closing lof file.
xinit: giving up
xinit: unable to connect to X server: No such file or directory
xinit: server error

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

Fatal server error:
[1299.174] (EE) Caught signal 11 (Segmentation fault). Server aboring.

or alternatively a Signal 6:

Fatal server error:
[1299.174] (EE) Caught signal 6 (Aborting). Server aboring.


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


Create and edit the xorg.conf file:

Xorg -configure
mv /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.

Many thanks, this solved our Proxmox 7.3 install.
I can confirm it works with the 7.3 iso. After editing the xorg.conf file all X related processes need to be killed before running startx.

Yes!, it works with 7.3, but I only added: Driver "fbdev"
