Hello,
I'm trying to install my new server with LEAP 15.2 :
- Supermicro H11SSl-I motherboard with AMD EPYC 7402P processor ans 128 GB memory
- Asus RX580 Dual Series 8 GB RAM
- 2x1 TB SSD in RAID 1
- The BIOS is up to date
This MB has an integrated video (AST2500) with VGA output and in the BIOS I defined the primary video output as external card. It's OK : the BIOS is displayed with the RX580.
When I try to install LEAP with network USB Key, I only can see the beginning : grub menu, then only two lines and the display becomes black. I have to switch to the internal VGA port to continue installation.
The RX580 is detected and all seems OK but no display with it. I tested two DVI cables, two monitors and even a DisplayPort connection.
At reboot I can only see grub, then the splash Opensuse screen for a few seconds, then black screen and I must switch to VGA port.
I tested Tumbleweed installation : same problem.
I tested nomodeset or amdgpu.dc=0 parameters for grub, no result.
I tested live CD LEAP and Ubuntu 19.10 : same problem.
i tested the last AMD driver (19.50) : same problem.
I don't see any error in dmesg and Xorg.log.

The driver seems to be loaded.
I can post Xorg.log and dmesg if needed.
Thanks in advance for help, I think I tested all I know !
I'm afraid I have to buy another video card, from NVIDIA this time ! it was my first time with AMD and Linux... The card was OK in Windows.
Best Regards
Nicolas
