Bug Description
The previous kernel 6.5.0-17 worked fine. With -26, the gdm login screen is only 640x480. I inspected the changelog from -17 to -26 and found '- Revert "drm/ast: report connection status on Display Port."' in the list. I found the reverted patch at https:/
I then built the 6.5.0-26 package with the "report connection" patch added and the resulting kernel has the correct resolution now.
Why was the "report connection" patch reverted? Can it please be put back in?
Hardware tested - Supermicro SYS-241E-TNRTTP. lspci shows this info for the ASPEED video controller:
02:00.0 VGA compatible controller: ASPEED Technology, Inc. ASPEED Graphics Family (rev 52)
02:00.0 0300: 1a03:2000 (rev 52)
