Hi i have a problem with Debian 12 after Installation. Every time i try to log in to the Desktop Environment or WM my Screen goes black. The PC completely freezes and i cant switch to another TTY.
I reinstalled Debian 12 a few times via netinstall. Tried different Desktop Environments and WMs. The Installation runs through without any issues. Running Debian without graphical environment (Terminal only TTY) is running fine. Installing packages via apt is also fine. As soon as i install a DE or WM and restart the machine, the screen goes black (after showing the boot screen). I cant log in to any Desktop. I also tried booting the Live ISOs of Debian 12 Gnome and XFCE edition. And Fedora Workstation 38 Live ISO. All of them have the same issues. I found out that Linux runs fine when i took the AMD GPU out of the PC. Running Linux only with internal Intel GPU. As soon as i put the AMD GPU back in its starting to freeze / black out again. Drivers and Firmware are installed following this wiki: https://wiki.debian.org/AtiHowTo The Systems Specs are: Mainboard MSI CSM-Q87M-E43 (MS-7830) Intel i5-4570 Graphics AMD Radeon R9 390 (Powercolor) 16 GB Ram Corsair DDR3-1333 SSD Gigabyte GP-GS 500GB I had no issues with Windows 10 on this machine. 3D games and everything runs fine.
